Description

Continuous construction method of box channel and formwork

The present invention relates to a continuous construction method of the box-type waterway and formwork thereof to allow agricultural water, domestic sewage and sewage to flow in the ground. Conventionally, concrete pipes have been purchased underground to make waterways in the ground.

In order to purchase concrete pipes in the underground, the trench was first drilled at the site where the waterway was constructed, and the bottom of the trench was firmly solidified.

Therefore, when purchasing a channel into the ground with concrete pipes, there were the following problems.

First, it was expensive because the concrete pipe itself was relatively expensive, and because it was heavy, the concrete pipe was transported to the waterway construction site by vehicle, and it was very difficult and difficult to transport the concrete pipe where the vehicle could not travel. .

Second, it was very cumbersome to put down the concrete pipe to the dig and to make the pipe joint so as not to leak from the connected area.

Third, there was a high risk of leaking pipe joints easily due to the load applied when the vehicle passes over the channel where the ground has subsided or covered after construction, and if the water flowing through the channel is sewage, it has contaminated the environment.

Fourth, the construction cost was long because the construction period was long and many manpower was required.

The present invention is to solve the above problems of the prior art, an object of the present invention to provide a method and a continuous formwork for the continuous construction of the seamless box-shaped canal immediately in the field to be constructed.

Between the flanges 16 and 16 'and the inner wall and the ceiling members 12 and 12', the space part 32 by the said protrusions 20 and 30 exists.

Therefore, as illustrated in FIGS. 3B and 4, the screw rod is locked between the grooved steels 10 and 10 'of the inner formwork A and the grooved steels 56 and 56' of the outer formwork B. (62) and a screw rod locked between the inner wall of the inner formwork (A) and the ceiling members (12), (12 ') and the outer wall forming members (58), (58') of the outer formwork (B). 76), the threaded rod (40) fixing the inner wall of the inner formwork (A) and the members 12 and 12 'for ceiling construction, and the grooved steel (10), (10) of the inner formwork (A). ') And the grooves (10) and (10') can be easily removed from the inside when the mold is dismantled by releasing the bolt (34) fixing the inner wall and the ceiling members (12, 12). The inner formwork (A) can be easily dismantled while moving.

The present invention can reduce the construction cost and manpower because the box-type waterway 100 can be continuously and seamlessly while repeating the assembly and disassembly of the internal formwork (A) and the external formwork (B) at the construction site, The construction period can be shortened, and the structural strength is large, so even if the vehicle passes on the completed waterway 100, there is no fear of being damaged or leaked, and the anchor 110 is fixed to the hole 104 on the side wall to purchase a communication table or wire. There is an advantage such as to support the underground buried material 112, such as a pipe or gas pipe.
