Description
Technical field
The present invention relates to the steel pipe sheet construction methods at tunnel connection channel construction.
Technical background
Metro Connection Passage is normally at the centre position of running tunnel, be often equipped at this catchment, drainage pumping plant, play
The effects that two tunnels connect, catchment, drain and prevent fires has the title of " escape route ".Metro Connected Passage-way Construction is generally in tunnel
It is carried out again after the completion of agent structure, first makes service channel periphery freezing soil with freezing mostly in Practical Project, form intensity
Then height, the good Frozen Soil Cylinder of closure use Mining Method to carry out the excavation construction of service channel, Freezing stratum as rapid and excavation
Construction carries out in running tunnel.
The freezing consolidation soil body has nearly semicentennial engineering experience in China, mainly has the advantage that：Have compared with
High safety can effectively completely cut off underground water；It is applicable in any loose Rock And Soil containing certain water, in complex hydrologic geology
Under the conditions of freezing technology it is effective, feasible；Construction is flexible, can artificially control freezing body shape and spreading range, when necessary
It can be freezed around underground obstacle, the consolidation by freezing soil body is uniformly, completely.
Different processes can lead to act on the external force on the section of jurisdiction closed on and be distributed in various degree during construction freezing method
Change, causes uncertain segment deformation, influence the safety of tunnel structure.Therefore, it is necessary to be directed to service channel freezing process
Construction is designed, and is reduced influence of the Freezing Method for Cross-passage Construction to tunnel agent structure with this, is reduced construction risk.
Invention content
It is an object of the invention to weaken the adverse effect of construction freezing method in Freezing Method for Cross-passage Construction to tunnel agent structure,
A kind of detachable steel tube section constructing method suitable for construction freezing method at tunnel connection channel is provided.
The technical solution adopted in the present invention is：
A kind of detachable steel tube section constructing method for construction freezing method at tunnel connection channel, this method is for tunnel
At road service channel in the detachable steel pipeline section of construction freezing method, in addition to using ordinary crossing section of jurisdiction part 3, also use non-disconnectable
Part 1 and free section 2 arrange free section 2 at tunnel connection channel, and non-disconnectable part is arranged on 2 periphery of free section
1, free section 2 is connected with ordinary crossing section of jurisdiction part 3 by non-disconnectable part 1, to constitute complete detachable steel pipeline section；
Non-disconnectable part 1 therein sets gradually three layers of outer layer sheet metal, flexible transition base and internal layer steel construction section of jurisdiction from outside to inside；
It is respectively provided with freezing hole, relief hole and thermometer hole on non-disconnectable part 1 and free section, list is fixed at freezing hole and relief hole
To valve；Construction method is：
1) detachable steel pipeline section is installed as described above；
2) freezing hole and relief hole construction；
3) construction freezing method forms freezing curtain；
4) free section 2 is removed, and then carries out Mining Method Freezing Method for Cross-passage Construction.
The flexible transition base is rubber spacer, and the mesh for penetrating rubber spacer is distributed on rubber spacer.Mesh is cut
Area corresponds to the 20% of sectional area less than rubber spacer.
Special pipeline section is suitable for construction freezing method at the tunnel connection channel that the present invention uses, and Pass through above-mentioned technical proposal carries
The high durability of section of jurisdiction, adverse effect of the soil body to tunnel structure is freezed in tunnel periphery when reducing construction freezing method, improves
The safety of structure.Non-disconnectable part forms frozen soil curtain when reducing construction freezing method by the way that flexible transition base is cleverly arranged
Curtain stress concentration effect caused by section of jurisdiction, improves safety and the durability of structure.
The design of the present invention is described further with concrete structure below with reference to attached drawing, to fully state the present invention's
Feature.
