The non-removable track crossing underground factory is largely divided into aisle (1), excavation visor (2), excavation blade (3), and indentation device (4) for aisle passage.

In Fig. 1, the passageway 1 promotes the safety of perforation when opening the underground passage in a non-adhesive way under the track, and after opening the underground passage, the floor, wall and ceiling integrated passage wall of the underground passage are opened. It is made of reinforced concrete or PC, corrosion-resistant thick steel plate with sufficient strength, and reinforced steel on the inside and outside of the thick steel plate and hardened by shotcrete. Such a passage 1 is also possible for pedestrians, farm equipment, as well as vehicle traffic depending on the size. Arched and square tubes are preferred, and their lengths are designed and manufactured to match the width of the existing track.

A nut 5 is planted at the top and both sides of the passageway 1 at equal intervals so that the rear end of the excavation visor 2 is fixed with a bowl, and a cushioning rubber plate 6 is attached to the corner of the rear end. When pushing back with the push indenter to move in the digging direction, it is protected from being damaged even if it comes into contact with the hydraulic system, and also prevents the tip of the hydraulic system from slipping.

The excavation visor (2) is mounted on the tip of the aisle (1) to support the excavation work on the underground passage area and the ground (1) By securing the floor safely and supporting the drilling blade, the excavation work on the side of the Raya passage hole is easy because the drilling blades mounted on the ends of the ceiling 22 and the lower 11 are excavated. To form a slanted surface 23 that is inclined from the tip of the ceiling 22 toward the bottom of the tip of the passageway 1. At this time, the inclined surface 23 has the same inclination angle as the repose angle of the soil.

The outer periphery of the excavation visor (2) is the same as the outer periphery of the aisle (1) by using the excavation visor (2) and the excavation blade (3) to make it easy to press the aisle (1) while drilling the passage hole In addition, after the passageway (1) is installed, there is no gap between the passage hole and the passageway (1) to reduce the possibility of settlement of the roadbed after opening the underground passage.

In order to dig up roadbed soil that is out of reach when digging holes, a separate device such as a ladder is required. The use of ladders in the excavation visor 2 can be an obstacle and cumbersome to subsequent work going on to install the aisle 1. In view of this point, by installing the answer plate 24 in the excavation visor (2), the worker can go up easily to proceed with the excavation work for the roadbed. The answer plate 24 tilts the front slightly higher than the rear so that the excavated soil is easily pushed back. In addition, the vertical partition plate 12 for dividing the inside of the excavation visor 2 into a plurality of parts is installed at right angles to the answer plate 24 to prevent the soil from collapse. At this time, the number of partitions for dividing the stationary visor is determined according to the type of soil to be excavated and the size of the excavated visor.

In the rear end of the excavation visor (2) perforation of the attachment hole 25 in the same position as the nut (5) to be easily fixed to the nut (5) with a bowl against the tip of the passageway (1). A chute (not shown) is attached to the rear end of the answer plate 24 so that the excavated soil is easily loaded on the transport vehicle.

The excavation blade (3) is to dig the ceiling side of the aisle through which the aisle (1) will enter first to facilitate the excavation work of the roadbed and the aisle (1), the ceiling of the excavation visor (2) (22) hingedly attached to the tip of the lower part (11), the angle of excavation (2) to adjust the angle of the excavation blade (3) in the excavation visor (2) with the excavation angle adjuster (7) Adjust the height of excavation. Both threaded rods 71 and 72 of the excavation angle adjusting mechanism 7 are hinged to the bevel 23 of the excavation visor 2 and the claws 27 and 31 attached to the bottom surfaces of both ends of the excavation blade 3. Install. Angle adjustment of the excavation blade 3 is performed when the excavation angle or the height of the passageway shifts.

In FIG. 3, the passage girder indentation apparatus 4 is a hydraulic apparatus using hydraulic pressure as the passage girder 1 coupled with the excavation visor 2 is pushed backward in the excavation direction of the passage hole.

Next, an underground passage construction method using the non-adhesive track crossing underground passage construction device will be described.

In Fig. 3, the ground on the line extending in the transverse direction is arranged outside the place where the underground passage crossing the existing tracks such as roads, railways, etc., is wider than the bottom width of the passageway passage 1, and the passageway passage 1 And hydraulic passageway press-fitting device (4) to the foundation to put the length of the concrete (a) to the length and then arrange the bottom smoothly to cure.

The rolled sheet 8 (e.g., P. F. Film, etc.) is laid several times so that it may be released to the excavation direction on the foundation concrete (a), and the channel | channel 1 is correctly mounted on the sheet 8. The sheet 8 is a synthetic resin film having a smooth and thin surface, which is easy to move by reducing frictional resistance when pushing the passageway 1 in the excavation direction from the upper surface of the foundation concrete a and the bottom of the excavated passage hole. .

Place the rear end of the excavation visor 2 on the tip of the passageway 1, align the center of the attachment hole 25 with the center of the nut 5, and then tighten the bolt 9 from the attachment hole 25. Fix it.

And by installing the passage indentation device 4 in the rear of the passageway (1) and fixed so as not to slip backwards, the front end of the hydraulic device 43 is adjusted to reach the rubber plate (6) of the passageway (1).

In FIG. 4, hydraulic pressure is applied to the hydraulic device 43 to push the passageway 1. The pusher passage 1 pushes and slides while the front end of the bottom 11 releases the multiple sheets 8. At this time, the excavation blade (3) cuts into the ceiling and the bottom of the passage hole. This operation proceeds until the tip of the bottom 11 of the passageway 1 reaches the bottom of the side surface of the roadbed b. Then the excavation visor (2) is also embedded in the roadbed (b).

The excavation worker enters through the rear end of the aisle 1 to excavate the roadbed b in the excavation visor 2, and the excavated soil is discharged toward the rear end of the aisle 1. The excavation on the roadbed (b) is such that the excavated passage hole (c) has the same height as the top surface of the foundation concrete (a) so that the passageway (1) can be easily pushed in, and the bottom is adjusted evenly. . And it drills deep so that the subsequent press-fit of the passageway 1 is possible. During excavation of the roadbed (b), a vertical partition plate (12) which divides the excavation visor (2) and the inside of the excavation visor (2) into a plurality of parts at right angles with the answer plate (24) is installed. It prevents it from falling down. At this time, the number of partitions for dividing the stationary visor is determined according to the type of soil to be excavated and the size of the excavated visor.

In FIG. 5, the second hydraulic pressure is applied to the hydraulic device 43 to press-fit until the tip of the bottom 11 reaches the bottom d end of the excavated passage hole c. At this time, the front end of the bottom 11 pushes and releases the multiple sheets 8, and the passageway 1 slides and press-fits the sheet 8. At the position, the roadbed b is again excavated in the same manner as described above. This operation is repeated until the passage hole c is fully opened. If the excavation angle and the height of the aisle shifts, operate the excavation angle adjusting mechanism (7) to correct it.

In Fig. 6, after the passage girder 1 is completely press-fitted into the opened passage hole c to stabilize the passage girder 1, the excavation visor 2 is removed from the passage girder 1, and the foundation concrete After disassembling the passage indenter 4 of (a), the surroundings are cleared up. As a result, underground passages crossing the route are constructed like a persimmon without having to open the track.

As described above, when the underground passage crossing the track is opened using the non-removable track crossing underground passage construction device of the present invention, the construction work is very quick and simple, and economical construction is possible.
