Kinetic energy improves the structural strength of vault to reduce the vibration frequency at tunnel vault.
The further setting of the present invention is that the tunnel parietal layer is equipped with the sluice being connected with water collection chamber at road
Switch, and be provided in the water collection chamber and switch the suction pump being connected with sluice.
By using above-mentioned technical proposal, sluice switch and suction pump are set, so that the water in water collection chamber is discharged, improve collection
The multifunctionality of water in water cavity, can be used for putting out a fire or cooling down sprinkling, it is ensured that the safety at where tunnel.
The further setting of the present invention is, the water proof pocket of connection water injection hole and suction pump is equipped in the water collection chamber
Bag, and the water proof pocket is made of two rubber membrane sweat solderings.
By using above-mentioned technical proposal, water proof pocket is set, damage of the moisture to structure at vault, while water proof are prevented
Pocket can deformation rubber membrane can be made to squeeze and absorbed in acoustical cotton then when suction pump carries out vacuumize process to water proof pocket
Moisture, to squeeze out remaining moisture, consequently facilitating dry water proof pocket.
The second object of the present invention is to provide a kind of method for tunnel construction, for above-mentioned tunnel, convenient construction and the letter of constructing
It is single.
The second purpose of above-mentioned technology of the invention has the technical scheme that a kind of constructing tunnel side
Method, application and construction include the following steps in a kind of above-described tunnel, S1, excavate logical Tunnel；S2, it is built using steel plate
For pouring the space of retaining wall layer, and the space of reserved water collection chamber and one end of pre-buried connecting column；S3, successively installation fitting shield
The rubber membrane of parietal layer, the corrugated steel for being enclosed with acoustical cotton and be bonded tunnel parietal layer rubber membrane, and after sweat soldering formed every
Water pocket installs the suction pump being connected with water proof pocket；S4, the space for pouring tunnel parietal layer is built using steel plate, and buried
The other end of connecting column, and the through-hole at reserved sluice switch place；S5, connection suction pump and sluice switch.
