The sub-pier main body 110 forms a truss shape by connecting a plurality of pipes 111, 112, 113, and 114 to each other, and a plurality of accommodation spaces 110a are formed by the plurality of pipes 111, 112, 113, and 114 do. The pipes 111, 112, 113, and 114 are made of SUS material to prevent corrosion, and are preferably manufactured with an appropriate thickness in consideration of manufacturing cost and weight. In this embodiment, the pipes 111, 112, 113, and 114 have a circular cross section, but are not limited thereto and may have various shapes.

The sub-bridge body 110 may include a plurality of upper pipes 111, a plurality of lower pipes 112, a plurality of first connection pipes 113, and a plurality of second connection pipes 114. The upper pipe 111 and the lower pipe 112 are located spaced apart from each other. The first connection pipe 113 is vertically coupled to the upper pipe 111 and the lower pipe 112. In the present embodiment, the sub-piers body 110 has a hexahedral shape by the plurality of upper pipes 111, the plurality of lower pipes 112, and the plurality of first connection pipes 113, but is not limited thereto. The plurality of second connection pipes 114 are diagonally coupled to the plurality of upper pipes 111 and the plurality of lower pipes 112. Since the sub pier body 110 includes the second connection pipe 114, the strength of the sub pier main body 110 having a truss shape can be reinforced. The sub-pierce body 110 may have a form in which a rectangular parallelepiped is stacked.

In this embodiment, when the sub-pier 100 is installed on the water surface, the lower pipe 112 is located below the water surface L and the upper pipe 111 is located above the water surface L. When the sub-bridge body 110 has a rectangular parallelepiped stacked form, only some of the lower pipes 112 may be located under the water surface L.

In this embodiment, a plurality of pipes 111, 112, 113, and 114 are joined by welding a portion where the pipes 111, 112, 113, and 114 are in contact. At this time, as shown in Fig. 4, in order to allow the pipes coupled to the side surfaces of the cylindrical pipes 111, 112, 113, and 114 to be joined without gap, the ends of the pipes to be joined are rounded inward. 4 is a view showing that the pipes of the sub-piers body of FIG. 1 are coupled to each other.

A railing 121 may be installed at the edge of the upper pier 120.

5 is an exploded view showing the buoyancy body of FIG. 1, and FIG. 6 is a conceptual view showing the buoyancy body is coupled to the accommodation space of the sub-pier body of FIG. 1.

As shown, the buoyancy body 130 may be installed in a plurality of accommodation spaces 110a formed in the sub-pier body 110. The buoyancy body 130 may be plural. When the plurality of buoyancy bodies 130 are installed in all the receiving spaces 110a formed in the sub-piers body 110, the influence of the fluid (wave and wind) on the sub-piers 100 increases. Accordingly, as shown in FIG. 3, it is preferable that the buoyancy body 130 is installed in a part of the accommodation space 110a to secure a space through which the fluid passes. However, the buoyancy body 130 may be densely disposed at a portion of the sub-pier body 110 to which the footbridge is connected to reinforce buoyancy. That is, in the present invention, the buoyancy body 130 is concentrated and arranged in a portion requiring buoyancy, and the number of buoyant bodies 130 is reduced in a portion affected by an external force, so that the auxiliary pier 100 can be efficiently manufactured.

The buoyancy body 130 may include a foam member 131 formed to be floatable and a plurality of metal covers 132 surrounding the outer surface of the foam member 131, as shown in FIG. 5.

In the present embodiment, the foam member 131 is formed of expanded polystyrene (EPS), but is not limited thereto, and various materials capable of generating buoyancy may be used. In this embodiment, the foam member 131 has a hexahedral shape according to the shape of the accommodation space 110a. The plurality of metal covers 132 surround the six surfaces of the foam member 131 to conceal the foam member 131 therein. The metal cover 132 may be made of SUS. By the metal cover 132, the buoyancy body 130 can be safely protected from external shocks (wave, wind, etc.) or collision (ship).

The buoyancy body 130 described in this embodiment is only one example, and of course, it can be replaced with various configurations. For example, there may be a pillar structure having a square or circular structure in which the inside can be sealed by forming a single buoyancy space inside by replacing the foam member 131.

In order to couple the buoyancy body 130 to the sub-bridge body 110, as shown in FIG. 6, a pipe connection pipe 115 is attached to the first connection pipe 113 of the sub-bridge body 110. A flange 115-1 is formed at the end of the pipe fitting pipe 115. A buoyancy body fitting pipe 135 is attached to the metal cover 132 of the buoyancy body 130. A flange 135-1 is also formed at the end of the buoyancy body fitting pipe 135. When the buoyancy body 130 is located in the accommodation space 110a of the sub-bridge body 110, the flange 115-1 of the pipe fitting pipe 115 and the flange 135-1 of the buoyancy body fitting pipe 135 are They come into contact with each other. At this time, each of the flanges 115-1 and 135-1 is coupled by bolting or the like. In FIG. 6, one flange 115-1 and 135-1 is provided on all sides to couple the buoyancy body 130 to the sub-pier body 110, but is not limited thereto. That is, by forming a plurality of each of the flanges 115-1 and 135-1 up and down, the buoyancy body 130 can be more firmly coupled to the sub-bridge body 110.

The buoyancy body fitting pipe 135 may be attached to the flat surface of the metal cover 132, but it is preferable to be attached to the corner of the metal cover 132 for stable support of the buoyancy body 130. To this end, the coupled end of the buoyancy body fitting pipe 135 may be processed to have an angle corresponding to the corner of the buoyancy body 130 inward.

FIG. 7 is a diagram conceptually illustrating an example in which a pipe reinforcement material is coupled to a pipe in the sub pier of FIG. 1, and FIG. 8 is a view conceptually illustrating another example in which a pipe reinforcement material is coupled to a pipe in the sub pier of FIG. 1, and FIG. 9 Is a view showing that a plurality of pipe reinforcements are installed in the pipe in the sub-pier of FIG. 1, FIG. 10 is a view showing that a plurality of pipe reinforcements are inserted into the pipe at three angles in the sub-pier of FIG. 1, and FIG. 11 is It is a view showing that a plurality of pipe reinforcements are inserted into the pipe so as to form different first angles and second angles in the sub-piers of

The pipe reinforcement 140 is inserted into and fixed to the pipes 111, 112, 113, and 114 constituting the body 110. By inserting the pipe reinforcement material 140 into the pipes 111, 112, 113 and 114, the rigidity of the pipes 111, 112, 113, and 114 increases. In particular, when the main body 110 of the sub-pier 100 has a truss shape as in the present invention, it is important to increase the rigidity of the pipes 111, 112, 113, and 114. The pipe reinforcement 140 may have various shapes such as a cylindrical shape, a prism shape, and a plate shape. Considering that the strength of the main body 110 is to be reinforced, it is preferable that the pipe reinforcement 140 has a plate shape. This is because the plate-shaped pipe reinforcement 140 has a greater resistance to a load (bending moment) acting in the radial direction of the pipes 111, 112, 113, and 114.

As an example, the pipe reinforcement 140 is inserted through the side of the pipe 111 as shown in (a) and (b) of FIG. 7. To this end, slot holes may be formed at the first position P1 and the second position P2 on the side of the pipe 111, respectively. The pipe reinforcement member 140 is inserted into the slot hole at the first position P1 to reach the slot hole at the second position P2. When the insertion of the pipe reinforcement 140 is completed, the pipe reinforcement 140 and the pipe 111 are welded (W) in each slot hole. The pipe reinforcement 140 is fixed through welding (W), and water can be prevented from entering the pipe 111.

In another embodiment, as shown in FIGS. 8A and 8B, a slot hole is formed in the first position P1 of the side of the pipe 111, and the pipe reinforcement 140 is formed in the second position P2. A perforated hole is formed through which) cannot pass. A plurality of perforated holes may be formed. The pipe reinforcement member 140 is inserted into the slot hole of the first position P1 to reach the second position P2. At this time, since the pipe reinforcement 140 cannot pass through the perforated hole, the pipe reinforcement 140 comes into contact with the inner wall of the pipe 111. In this state, the pipe reinforcement 140 and the pipe 111 are welded (W) in the slot hole and the perforated hole. When the pipe reinforcement 140 is fixed by forming the perforated hole in the second position P2 as described above, the working time can be shortened compared to forming the slot hole, and construction cost can be reduced.

The pipe reinforcement 140 may be plural. A plurality of pipe reinforcements 140 are inserted into one pipe 111 and fixed while being disposed to cross each other in the longitudinal direction of the pipe 111.

In this case, the pipe reinforcement 140 may have different angles inserted into the side of the pipe 111 and the pipe reinforcement 140 adjacent to each other. In one embodiment, as shown in FIG. 9, a plurality of pipe reinforcements 140 are inserted to form a right angle to each other. In another embodiment, as shown in FIG. 10, a plurality of pipe reinforcements 140a, 140b, 140b may be inserted at three or more angles.

In another embodiment, as shown in FIG. 11, the first pipe reinforcement 140a and the second pipe reinforcement 140b adjacent to each other may achieve different first angles θ1 and second angles θ2. have. The second angle θ2 is smaller than the first angle θ1. In order to have a stronger rigidity against the external force (F) applied to the pipe 111, it is preferable that the second angle (θ2) faces the external force (F). As such, the main body 110 may determine the insertion direction of the pipe reinforcement 140 in consideration of the direction of the external force F applied to the pipe 111.

FIG. 12 is a view showing that an anchor chain is coupled to a lower pipe of a main body of an auxiliary pier of FIG. 1.

As shown in FIG. 12, in the sub-bridge 100 according to an embodiment of the present invention, an anchor chain 150 may be coupled to the lower pipe 112. The auxiliary pier 100 needs an anchor for fixing, and the anchor needs to move up and down between the auxiliary pier 100 and the underwater bottom surface. These anchor chains corrode quickly when exposed to water frequently. The present invention is coupled to the lower pipe 112 so that the anchor chain 150 can move only under the water surface to solve this problem. The anchor chain 150 and the lower pipe 112 may be joined by welding.

When the anchor chain 150 is coupled to the lower pipe 112, a large load is applied to the lower pipe 112. In order to solve this, a pipe reinforcement member 140 is installed on the lower pipe 112. Even if the anchor chain 150 is coupled to the lower pipe 112 having the pipe reinforcement 140, the lower pipe 112 is not bent or broken by a load (bending moment). That is, the pipe reinforcement member 140 has a slot hole formed in the first position P1 on the side of the lower pipe 112 in the longitudinal direction of the lower pipe 112, as shown in the enlarged portion of FIG. In the second position P2, a plurality of perforated holes through which the pipe reinforcement 140 cannot pass is formed. The pipe reinforcement member 140 is inserted into the slot hole of the first position P1 to reach the second position P2. At this time, since the pipe reinforcement 140 cannot pass through the plurality of perforated holes, the pipe reinforcement 140 comes into contact with the inner wall of the pipe 111. In this state, the pipe reinforcement member 140 and the lower pipe 112 are welded in the slot hole and the plurality of perforated holes. When the pipe reinforcement 140 is fixed by forming a plurality of perforated holes in the second position P2 as described above, the working time can be shortened compared to forming the slot hole, and construction cost can be reduced. The pipe reinforcement 140 may be plural. The plurality of pipe reinforcements 140 are inserted and fixed while being disposed to cross each other in the longitudinal direction of the lower pipe 112.

In another embodiment, concrete may be poured into an empty space inside the lower pipe 112. When concrete is poured into the lower pipe 112 and cured, the rigidity of the lower pipe 112 increases. In addition, since the weight of the lower pipe 112 located at the lower side of the main body 110 increases, the center of gravity of the sub-pier 100 is stably formed, and overall stability is increased, such as a decrease in vibration due to external force.

13 is a view showing that a pipe reinforcement is installed in the mooring column of the sub-pier of FIG. 1.

As shown in FIG. 13, in the sub-pier 100 according to an embodiment of the present invention, at least one mooring post 170 to which a rope is connected may be coupled to the upper pipe 111 of the edge. The mooring column 170 includes a vertical pipe 171 that is coupled by welding a portion in contact with any one of the upper pipes 111, and at least one that extends horizontally to a predetermined height of the vertical pipe 171 to prevent separation of the connected rope. It includes a horizontal pipe 172. At this time, the vertical pipe 171 is processed to be rounded inward at the end to be joined to be joined to the upper pipe 111 without gap. The horizontal pipe 172 is processed to be rounded inward at the end to be coupled to be joined to the vertical pipe 171 without gap.

Since external force in the horizontal direction is concentrated in the vertical pipe 171 of the mooring column 170 by the shaking of the sub-pier 100 due to wind and waves, a pipe reinforcement 140 is inserted therein to reinforce the rigidity against external force. To this end, slot holes may be formed at the first position P1 and the second position P2 on the side of the vertical pipe 171, respectively. The pipe reinforcement member 140 is inserted into the slot hole at the first position P1 to reach the slot hole at the second position P2. When the insertion of the pipe reinforcement 140 is completed, the pipe reinforcement 140 and the vertical pipe 171 are welded in each slot hole. The pipe reinforcement 140 is fixed through welding, and water can be prevented from entering the vertical pipe 171. The plurality of pipe reinforcements 140 may be plural. A plurality of pipe reinforcement members 140 are inserted and fixed while being disposed to cross each other in the longitudinal direction of the vertical pipe 171.

In addition, various methods described in FIGS. 8 to 11 may be used as a form of reinforcing the rigidity of the mooring column 170 by inserting a plurality of pipe reinforcements 140.

FIG. 14 is a view showing that the sub pier of FIG. 1 is coupled to another sub pier, and FIG. 15 is a view showing that the first connecting pipes of two adjacent sub piers are coupled to each other in FIG. 14, and FIG. It is a diagram showing the combined cross section of the combined sub-pier.

As shown in FIG. 14, a sub-pier according to an embodiment of the present invention may be connected to another adjacent sub-pier. To this end, joint pipes 160 are installed horizontally at adjacent portions of each sub-pier, that is, the first connection pipe 113 of each sub-pier. The joint pipe 160 is processed to be rounded inward at the end of the joint pipe to be joined to the first connection pipe 113 without gap. Flanges 161 are respectively installed at ends of the joint pipes 160 adjacent to each other to be coupled to each other.

Since the load (bending moment) is concentrated at the joint portion of the flange 161 of the joint pipes 160 by waves and wind at sea, the connection structure between the sub-piers 100 may become weak. To solve this, a joint pipe reinforcement material 165 is installed inside the neighboring joint pipes 160.

That is, as shown in Figs. 15 and 16, after inserting and fixing the joint pipe reinforcement material 165 into the joint pipes 160 communicated with each other adjacent to each other, the ends of the joint pipe 160 are flanged to each other. ) By combining, it is possible to safely maintain the connection between the sub-piers 100 by improving the rigidity of the connecting portion of the sub-piers.

The joint pipe reinforcement 165 includes a first plate 165-1 of a certain length and a second plate 165-2 of a certain length that is orthogonally coupled to the first plate 165-1. The joint pipe reinforcement 165 is preferably formed in a symmetrical cross-section considering that external force is applied to the flange 161 in various directions. However, in the present embodiment, the cross section of the joint pipe reinforcement 165 is cross-shaped, but is not limited thereto and may be formed in various shapes having a symmetrical structure. In addition, in the present embodiment, the number of plates of the joint pipe reinforcement 165 is two, but it is formed in a coupling structure of three or more to further improve the rigidity of the sub-bridge connection portion.

In order to fix the joint pipe reinforcement material 165 inside the joint pipes 160, a first plate 165-1 and a second plate 165-2 are connected to each other and communicate with each other. A plurality of guide holes 160a into which both ends of the width direction can be slidingly inserted are formed. In this case, the plurality of guide holes 160a are formed to have a predetermined length along the length direction of the joint pipe 160 at the end of the joint pipe 160. The length of the guide hole 160a is formed smaller than the length of the joint pipe reinforcement 165.

When the joint pipe reinforcement 165 is inserted into any one of the joint pipes 160 through the plurality of guide holes 160a, the joint pipe reinforcement 165 and the joint pipe 160 in each guide hole 160a Weld (W). Thereafter, the flange 161 is coupled to the end of any one of the joint pipes 160 by welding (W) while a part of the joint pipe reinforcement 165 protrudes to the outside of any one of the joint pipes 160.

Each guide hole 160a may be formed of a plurality of welding holes spaced at predetermined intervals in the longitudinal direction of the joint pipe 160. In this case, it is preferable that a plurality of guide grooves (not shown) formed in a predetermined length to communicate with the plurality of welding holes and guide the joint pipe reinforcement 165 are formed inside the joint pipe 160.

Welding is limited in water. In this embodiment, a part of the joint pipe reinforcement 165 protruding to the outside of one (right) joint pipe 160 for connection between the sub-piers 100 on the water surface is the other (left) joint pipe 160 Insert sliding inside.

At this time, a part of the protruding joint pipe reinforcement 165 is in contact with the inner wall of the joint pipe 160 of the other (left). To this end, as shown in FIG. 16, the width of the portion inserted into the inside of the other (left) joint pipe 160 is inserted into the inside of any one (right) joint pipe 160 and welded (W) It may be formed to be smaller than the width of the portion. However, the invention is not limited thereto. For example, the entire width of the joint pipe reinforcement 165 is formed the same, and the inner diameter of the other (left) among the joint pipes 160 coupled to each other is relatively larger than the inner diameter of any one (right). Can be formed.

Another flange 161 is coupled to the joint pipe 160 of the other (left side), so that the two sub-bridges are connected to each other by being bolted to the flange 161 of the neighboring joint pipe 160.

17 is a view showing a cross-section of another example in which the sub pier of FIG. 1 is coupled to another sub pier.

As shown in FIG. 17, a third plate 166 fixed through the joint pipe 160 of any one (right side) may be further installed in the sub-pier according to another embodiment of the present invention. To this end, a pair of through holes 160b facing in the radial direction are formed in any one of the joint pipes 160. After the third plate 166 is inserted through the through hole 160b, it is fixed to any one of the joint pipes 160 by welding (W).

Each of the joint pipes 160 is coupled to each other by welding the flanges 161 so that the two sub-piers are connected to each other by bolting the flanges 161 of the joint pipe 160 and the third plate 166 in the water.
