Problems solved by technology

[0004] First, because the tunnel excavation is carried out first, and then the erection process is carried out, the erection process needs to be carried out many times, which is very cumbersome and has certain safety hazards
[0005] Second, in order to carry out the erection process, a plurality of scaffolds 1 will be connected with a plurality of screws to be laid after tunnel excavation, which not only increases the difficulty of work, but also requires a lot of manpower, long construction period and uneconomical. construction progress is slow
[0006] Third, when excavating, if the excavation is too deep, when the foundation is weak, needless to say, the excavation process has a high risk of foundation or rock plate collapse or subsidence during the erection process after the excavation work. security incident
[0010] First, all the very long small-diameter pipelines 2 must be forcibly pressed into the steel pipes 10 for laying. When the length is relatively long, since there is no pipeline transmission pipe and adjustment device, it is difficult to control the directionality, and there are defects in the linear progress. , so it is difficult to lay
When the gaps between the steel pipes 10 are large, the small-diameter pipes 2 cannot prevent landslides, and a lot of equipment and construction costs will be consumed
When there are stones or the soil layer moves up, the direction changes, which makes the linear progress uncertain. When there are huge stones, the construction will be very difficult. When the filling work is carried out inside the steel pipe at the same time, the steel pipe will be corroded and become deformed. Fragile, difficult to prevent groundwater and soil loss, very uneconomical when filling the

Embodiment approach 1

[0062] refer to image 3 Process diagrams involved, to Figure 4 , Figure 5a , Figure 5b based on Figure 6a , Figure 6b , the first embodiment of the present invention will be described in detail.

[0063] Steel pipe pressing position measurement and transmission pipe laying process A:

[0064] Before the steel pipe 10 is pressed in, an accurate measurement is made at the appropriate position according to the planned tunnel construction face, and the input port 21 for preventing the collapse plate is formed at the front end of the steel pipe 10. Combined with the transmission pipe 20 with the press-in direction adjustment device 30, the steel pipe is pressed into the steel pipe. 10 preparations.

[0065] Steel pipe press-in process B:

[0066] The steel pipe 10 is placed at the exact propulsion position, and the hydraulic jack and propulsion auxiliary pipe are used to press in step by step, and the position measurement is carried out every 1M, and the press-in direc...

Abstract

The present invention relates to a method for laying structures of forming underground tunnel and its structure. It is different from before, the invention will not press the long distance small diameter pipeline that can not be constructed between the steel pipes, lays a wood made collapse proof plate by the collapse proof plate input port on the transmission pipe, so the construction is simple and the material cost is low, and because the lay of the transmission, the big stone and other obstacles can be removed quickly, thereby the lay is more simple and having good beeline degree.

Description

【Technical field】 [0001] The present invention relates to a method and structure for laying a structure for forming an underground tunnel, and is the technical content of Korean Patent Registration No. 217845 and No. 442712 to which I am the owner of the patent, that is, the soil and sand of the excavated part of the tunnel are not excavated, and The method of laying the tunnel-forming structure in the middle, allowing it to fully withstand the stress in advance, and then excavating the inner side of the structure to form an underground tunnel can be improved, and the construction of a strong and waterproof tunnel structure can be completed in a short period of time. 【Background technique】 [0002] Generally, in order to form a tunnel, it is necessary to lay a tunnel structure capable of withstanding the stress generated from the outside of the tunnel, and the conventional method of laying a tunnel structure will be described below. [0003] First, as figure 1 As shown in t...
