Description
Technical field
The utility model is related to the steel-tube construction at tunnel connection channel construction.
Background technology
Metro Connection Passage is normally at the centre position of running tunnel, at this often provided with catchmenting, drainage pumping plant, play
The effects such as two tunnels are connected, catchmented, draining and fire prevention, there is the title of " passway for escaping ".Metro Connected Passage-way Construction is general in tunnel
Carried out again after the completion of agent structure, first make the peripheral freezing soil of service channel with freezing mostly in Practical Project, form intensity
Then height, the good Frozen Soil Cylinder of closure carries out the excavation construction of service channel, Freezing stratum as rapid and excavation using Mining Method
Construction is carried 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 security, can effectively completely cut off underground water；Any loose Rock And Soil containing certain water is applicable, 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, if necessary
Underground obstacle can be bypassed to be freezed, the consolidation by freezing soil body is uniform, complete.
The external force that different processes can cause to act on the section of jurisdiction closed on during construction freezing method is distributed different degrees of
Change, cause uncertain segment deformation, influence the safety of tunnel structure.Therefore, it is necessary to be directed to service channel freezing process
The corresponding structure of detail design, influence of the Freezing Method for Cross-passage Construction to tunnel agent structure is reduced with this, reduces construction risk.
Utility model content
The utility model for weaken in Freezing Method for Cross-passage Construction construction freezing method to the adverse effect of tunnel agent structure there is provided
A kind of detachable steel pipeline section suitable for construction freezing method at tunnel connection channel.
The technical scheme that the utility model is used is：
A kind of detachable steel pipeline section suitable for construction freezing method at tunnel connection channel, including ordinary crossing section of jurisdiction part
3rd, non-disconnectable part 1 and free section 2, it is characterised in that free section 2 is disposed with tunnel connection channel, in removable portion
2 peripheries are divided to be disposed with non-disconnectable part 1, free section 2 is connected with ordinary crossing section of jurisdiction part 3 by non-disconnectable part 1, so that
Constitute complete detachable steel pipeline section；Non-disconnectable part 1 therein sets gradually outer layer sheet metal, flexible transition base from outside to inside
With three layers of internal layer steel construction section of jurisdiction.
Preferably, described flexible transition base is that the mesh for penetrating rubber spacer is distributed with rubber spacer, rubber spacer.
Mesh sectional area is less than the 20% of rubber spacer correspondence sectional area.
Freezing hole, relief hole and thermometer hole are equipped with non-disconnectable part 1 and free section 2, in freezing hole and pressure release
Check valve is fixed with hole.
Special pipeline section is applied to construction freezing method at the utility model tunnel connection channel, is improved by above-mentioned technical proposal
The durability of section of jurisdiction, adverse effect of the soil body to tunnel structure is freezed in tunnel periphery when reducing construction freezing method, improve
The security of structure.Non-disconnectable part is by cleverly setting flexible transition base to form Frozen Soil Cylinder when reducing construction freezing method
The stress concentration effect caused to section of jurisdiction, improves the security and durability of structure.
Design of the present utility model is described further with concrete structure below with reference to accompanying drawing, to throw a flood of light on this reality
With new feature.
