Problems solved by technology

[0003] Platforms are often used in the excavation and construction of flat holes. The use of platforms can greatly facilitate transportation. However, the existing platforms rely on manual control to move, which is time-consuming and laborious. The degree of automation is not high and the operating space is small.
At the same time, the existing flat hole construction has an unsatisfactory effect on the platform, and it is difficult to clean up the waste residue in the hole

Embodiment Construction

[0084] Such as Figure 1 to Figure 8 As shown, a platform for tunnel excavation includes a flat hole 1 and a platform 4. The platform 4 can accommodate equipment, construction personnel and waste residue, has a certain transportation function, saves time and effort, and significantly speeds up the construction progress. The upper end of the flat hole 1 is fixed with a straight rod, and the lower end of the straight rod is connected with a mobile support 2, and a cable 22 is installed in the mobile support 2, and the cable 22 runs through the mobile support 2. Mobile support 2 comprises first mobile support 23 and second mobile support 24, and first mobile support 23 and second mobile support 24 can be connected by flange 6, can be connected by flange 6 between the second mobile support 24, when construction When the personnel need to change the length of the mobile support 2, they only need to connect an appropriate number of second mobile supports 24 on the first mobile suppo...

Abstract

The invention discloses a rack for tunnel excavation and an adit construction method applying the rack. The rack is automatically controlled through a cable, construction accuracy can be improved, the moving range of the rack can be adjusted, and the rack is very suitable for adit construction. In addition, a device fixing apparatus is added on the rack, movement of a part of machines and tools is facilitated, the machines and tools can be used in the construction process at any time anywhere, and the working efficiency of the adit construction and construction effect can be remarkably improved. The adit construction method applying the rack is characterized by comprising the following steps of (a) construction preparation, (b) opening plane arrangement, (c) spoil area site selection, (d) protection and greening of a spoil area site, (e) opening excavation, (f) main tunnel first-stage construction, (g) rack assembly and (h) main tunnel second-stage construction. The main tunnel construction is performed in a two-stage mode, mutual reference can be achieved in the construction process, and project quality can be improved.

Description

technical field [0001] The invention relates to a platform for tunnel excavation and a flat tunnel construction method using the platform Background technique [0002] Construction benches are also called lining trolleys, which are mainly used for tunnels, water diversion tunnels, and secondary lining (secondary lining) concrete pouring. The trolleys are divided into two structures, one is a walk-through type and the other is a needle beam type. The trolley is mainly composed of a gantry frame and a formwork. The gantry frame is mainly load-bearing, and the formwork is designed according to the shape of the tunnel. It has the advantages of automatic walking, hydraulic automatic positioning and demoulding (up, down, left and right movement can be realized). [0003] Benches are often used in the excavation and construction of flat tunnels. The use of benches can greatly facilitate transportation. However, the existing benches are moved by manual control, which is time-consum...
