The utility model discloses beneficial effect is: after the shield constructed entrance to a cave rubber wipes gas distribution bag installation, it kept certain pressure to pressurization messenger in the gasbag, can obviously improve the shield and construct the sealed effect in the entrance to a cave, had greatly improved the shield and had constructed the security of starting.
Description
Technical field
The utility model relates to a kind of shield launching and receives hole hermetically-sealed construction, may extend to the application of shield crossing air channel, manhole and subway station.
Background technology
Current shield tunnel is domestic and international application the most a kind of tunnel piercing method, and shield construction is generally divided into three phases, i.e. shield launching, normal driving, reception.
When shield tunnel buried depth is darker, usual rich groundwater, the sealing problem at shield launching and reception hole place must draw attention, solid rubber cord plate is all adopted to seal in current engineering, but sealing effectiveness is not very remarkable, when particularly shield structure receives, because rubber curtain fabric swatch bending direction is consistent with shield driving direction, and and water, the shove flow direction of thing such as sand is consistent, therefore its sealing effectiveness is undesirable, often occur leaking, sand and mortar situation, even may occur that the hole soil body runs off in a large number and caves in, there is very large potential safety hazard.For this reason, shield structure hole must adopt more effective seal approach, hole water burst when reducing as far as possible and avoid starting and receiving, gushes the generation of husky phenomenon.
Summary of the invention
The purpose of this utility model is to provide a kind of shield launching and receives hole hermetically-sealed construction, to solve the not good problem of existing shield structure hole sealing device sealing effectiveness.
The technical solution of the utility model is: a kind of shield launching and reception hole hermetically-sealed construction, it is characterized in that, comprise annular pressing plate, annular connecting plate and annular air-pocket, be provided with the annular connecting plate with its integrative-structure in the periphery of annular air-pocket, be provided with the annular pressing plate be mated in the side of this annular connecting plate; This annular connecting plate and annular pressing plate are provided with the multiple installing holes for passing long bolt be uniformly distributed along the circumference.
Be provided with annular backing plate at the opposite side of described annular connecting plate, this annular backing plate is provided with the through hole corresponding with described installing hole.
Between described annular connecting plate and annular backing plate, be provided with annular steel collar, this annular steel collar is provided with the through hole corresponding with described installing hole.
The radial width of described annular connecting plate is 300 ~ 500mm, and thickness is 10 ~ 20mm; Described annular air-pocket diameter is 150 ~ 300mm, and thickness is 5 ~ 10mm; The spacing of the installing hole on described annular connecting plate and annular pressing plate is 50 ~ 100mm.
Described annular pressing plate employing thickness is that the steel of 10 ~ 15mm are made, and the radial width of this annular pressing plate is identical with the radial width of annular connecting plate.
Described annular connecting plate and annular air-pocket are made up of rubber curtain cloth.
Beneficial effect of the present invention is: after shield structure hole rubber curtain cloth air bag is installed, and in air bag, pressurization makes it keep certain pressure, obviously can improve shield structure hole sealing effectiveness, greatly improve the safety of shield launching.
