Description
Technical field
The utility model belongs to tunnel construction technical field.More specifically, it the utility model is related to a kind of shield machine
Reception device with pressure.
Background technology
Shield machine completes driving section and enters the critical process that received well process is shield method tunnel construction, and the process is applied
Work risk is the principal risk of shield-tunneling construction, directly affects the success or failure of engineering construction.Conventional shield machine receives work progress：
Termination stratum consolidation → shield machine cuts to stake → portal stake → sealing cord installation → shield machine appears → shield machine on receive
Pedestal → hole slip casting.The work progress has the following disadvantages and risk：
（1）Termination stratum consolidation cost is high, long construction period, consolidation effect can not accurate judgement, and by ground environment bar
Part limits；
（2）It is larger by formation condition restriction when portal is cut, greater risk be present；
（3）Shield machine is larger to stratum interference during appearing, and easily causes larger sedimentation, or even segment deformation, fragmentation；
（4）The construction can not or stratum larger in underground water it is unstable under conditions of carry out, special construction method need to be taken.
Shield machine is carried out in good ground using conventional method and receives basic feasible solution, but due to native in shield receive process
Pressure is gradually lowered to zero so that the accident such as easily occur caving in when receiving, the easy bigger thing of appearance if with the presence of underground water
Therefore.
In addition, increasing with the buried depth of underground engineering, underground water is extremely complex and the bad engineering such as drift sand easily occur
Matter phenomenon, traditional shield receive mode, can not meet that shield when buried depth is big receives, safety problem is more prominent.
For there is the construction environment of underground water, shield machine receive process are very risky, easily occur cave in, seep water, metalling run out
Equivalent risk, conventional method of reseptance of directly appearing can not meet that safety in production requires, before patent（CN200920058408 is a kind of
For shield machine closed origin and the device of arrival；A kind of casings of CN201210278021 and water rich strata shield casing receive
Method）Band ballasting method of reseptance, equipment is excessively heavy, it is necessary to larger receipt area, for lifting condition restricted clearance, it is difficult to
Implement.Above-identified patent technology meets that reducing leak leaks husky risk requirement, but huge structure, and work is assembled and disassembled for the vertical shaft of the confined space
Bring difficulty, invention is a kind of simple in construction, is easy to assemble and disassemble, while have very much must for the reception device with pressure that can reduce construction risk
Will.
