Description

Ultra-large amplitude variable pile frame type pile driving ship

Technical Field

The utility model relates to an ultra-large becomes width of cloth pile frame formula pile driving ship.

Background

Piling modes of the overwater pile foundation engineering are mainly three, namely variable amplitude pile frame type piling ship piling, platform or crane ship piling and vibrating hammer hanging piling. The second pile driving form is generally suitable for vertical pile foundation construction, is used for construction of large steel pipe piles of offshore wind power plants and offshore oil projects, and cannot be suitable for construction of wharf pile foundations and offshore wind power high-rise pile cap inclined piles; the third pile driving form construction generally uses small pile foundation construction such as steel sheet pile on water and offshore wind power platform fixing pile. The construction of the pile foundation of the projects such as the present harbor construction, ocean engineering, cross-sea bridge, offshore wind power high pile cap and the like basically adopts the first piling form.

The development of the variable-amplitude pile frame type pile driving ship is divided into four stages: the 40 m pile frame is in the middle of the 70 th generation, the 70 m pile frame is in the 90 th generation, and the 90 m pile frame is in the new century and the pile frame with the length of more than 100 m is in the present stage. However, in the last decade, new energy construction is vigorously advocated in China, offshore wind power is produced at the same time, the development speed is high, construction equipment cannot meet the market demand, the installed capacity is increased to 12MW from the initial 4MW, the water depth is increased gradually, the water depth of a wind field sea area of the offshore wind power reaches 40 meters, the longest length of a single inclined pile is 133 meters, the pile weight is over 340t, the wind field hydrological condition is severe, the wave length of surge is long, and the existing variable-amplitude pile frame type pile driving ship cannot complete the construction task. In addition, the engineering piles of the sea-crossing bridge are basically 80 meters long and more than 1.5 meters in pile diameter, and even larger piles are needed. Therefore, a novel ultra-large variable-amplitude pile frame type pile driving ship is urgently needed to be developed to meet the requirement of engineering construction.

The existing luffing pile frame type pile driving ship mainly has the following problems:

1) when the piling ship is used for piling, along with the increase of piling depth, the pile hammer moves closer to the lower end of the dragon mouth, the hammering force is larger and larger, and because the dead weight of the pile hammer is larger, the cantilever section at the lower part of the dragon mouth of the box-shaped structure can bear large radial load, the cantilever section at the lower part of the dragon mouth is supported by the backrest of the box-shaped structure at present, so that the weight of the whole pile frame can be increased, the section modulus of the pile frame is lower, the manufacturing cost is increased, the ship performance is influenced, and the type selection of the variable amplitude oil cylinder is restricted. At present, both a pile hanging platform and a hammer hanging platform are of box-shaped structures, forward cantilevers are long, and bending section modulus of box girders is large. Because the self weight of the pile frame and the gravity height greatly influence the stress of the variable-amplitude oil cylinder, the moment generated by the pile frame under the pile driving working condition accounts for about 35-40% of the total moment of the variable-amplitude oil cylinder, and the thrust of the variable-amplitude oil cylinder is determined by the weight of the pile frame and the gravity position under the inverted frame working condition. Therefore, on the premise of meeting the requirements of structural strength and rigidity, the pile frame structure is optimized, the weight of the pile frame is reduced as much as possible, the height of the center of gravity is reduced, and the method is one of the main means for reducing the cost and improving the use safety of the variable amplitude oil cylinder.

2) At present, when a pile frame of a pile driving barge is placed on a bracket, an upper fulcrum of a rear main pipe of a main pile frame is generally placed in a placing groove in which a hardwood is padded at the head of the bracket, and the bottom surface of the placing groove is an inclined surface matched with the inclination of the rear main pipe; the whole pile frame is supported by the support and the bracket on the bridge of the nose of a subject at three points. When the pile frame adopts the rear main pipe to support, the stability of the pile frame in a shelving state is poor, the swing of the pile frame in the towing process is more obvious, and in addition, because the inclination of the contact surface of the top surface of the bracket and the rear main pipe is consistent, the head of the bracket can bear horizontal force and generate great bending moment to the root of the bracket, so that the load of the bracket is increased.

3) The pile frame type pile driving ship generally adopts a diesel hammer hung on a dragon mouth to drive the pile. The striking energy of the diesel hammer is 200-300 kj, so that the energy efficiency is low, the pile sinking requirement of the offshore wind power large pile cannot be met, and particularly the pile foundation bearing platform foundation with the pile diameter of 1-3 m cannot be met. Because the energy efficiency of the hydraulic hammer acting on the pile top reaches 80 percent, the striking force and the energy efficiency are far greater than those of a diesel hammer, the multi-pile bearing platform of offshore wind power adopts the hydraulic hammer to sink the pile. At present, large-scale hydraulic hammers are used for hoisting and beating of crane ships. If the pile frame type pile driving ship is adopted to carry out pile sinking construction of offshore wind power, a large hydraulic hammer is required to replace a diesel hammer to be applied to the pile frame type pile driving ship. The hydraulic hammer is different and the diesel hammer, and the hammer block surface of hydraulic hammer does not have the longkou foot, can't directly carry out reasonable linking with the longkou of pile driving ship, and the hydraulic hammer is higher than the diesel hammer to the eccentricity requirement of stake.

4) The pile diameter range that very large pile driving ship can be executed is 1.6 meters-5 meters, the pile length is 80 meters-140 meters, therefore the sliding platform that can adjust the hammering center is equipped with on the drop hammer platform at the top of the pile frame. Under the circumstances at pile frame top adjustment hammering center, if adopt traditional pile gripper of fixed hammering center, then can't satisfy the construction requirement of stake position accurate positioning, and cause the damage of pile gripper, pile frame structure and accessory component easily.

5) The pile cap of the pile hammer is connected with a dragon mouth fixed in the middle of the front of the pile frame through a dragon mouth foot on the back of the pile hammer and can move up and down along the dragon mouth, the pile cap and the pile frame are relatively fixed and belong to static connection, and the steel pipe pile is tied and fixed with the main lifting hook through a pile hanging steel wire rope and is flexibly connected with the pile frame and belongs to dynamic connection. Along with the construction of the pile foundation, the sea area is more and more distant offshore, the water depth of the sea area is more and more deep, the natural conditions of the sea area are worse, the wind wave and the surge are larger, the pile frame height and other performances of the pile driving ship in site construction can be further improved, particularly, the pile length of the pile sinking is longer, the influence range of the wind wave of the sea area on the pile top is larger, after the pile erecting is completed in the construction process, the work that the pile cap of the pile driving hammer is required to be sleeved with the pile top at the top of the pile frame is more difficult, and the safety risk during construction is larger.
