Description
Technical field
The present invention relates to bored tunnel technical field of construction, more particularly to a kind of subway tunnel high strength support structure and
Its construction method, it is mainly used in its support reinforcement of metro tunnel excavation under weak broken formation condition.
Background technology
Recent year infrastructure construction is increasingly flourishing, and increasing city starts construction subway and gathered around with alleviating city
Stifled problem.Many subway lines have no alternative but pass through the bad stratum of the geological conditions such as backfill, weak soil, broken rock.This kind ofly
Layer bearing capacity and shearing strength are all very low, and larger, the progress subway construction pole on this kind of stratum is deformed after excavation disturbance
Easily cause larger differential settlement.In addition, creep or rheology can be produced after lining cutting is under confined pressure effect after constructing metro tunnel
Large deformation easily occurs for deformation, the support system such as lining cutting and unstability.At present, the serious deformation under weak broken formation condition is asked
Topic, it is the crucial problem during subway tunnel is built, brings great challenge to underground engineering construction, seriously constrain city rail
The safety of road transportation industry, high speed development.
Before making the present invention, the Invention Announce of Patent No. 201510101208.7 it is a kind of have never remove lining cutting wheel
The tunnel lining structure and its construction installation method of tire.Its main body is lining cutting tire and steel arch-shelf, determines lining cutting tire installation position
Put and tire shape after, pressure caused by surrouding rock deformation is uniformly passed to steel arch using the suppleness of air and rubber
Frame, the requirement of sectional shape area and intensity is reduced to a certain extent, avoid the local failure of steel arch-shelf.But the lining
The cardinal principle for building structure is to play itself support capacity using country rock, by the elastomeric property of the lining cutting tire contacted with country rock
Appropriate deformation occurs for power to discharge confined pressure, when using this method under the conditions of the weak broken formation of dead-soft, still easily deforms and is difficult to
Control and cause the possibility of supporting construction overall collapse.
A kind of shield tunnel liner glass fibre reinforced concrete pipe of Application No. 201710603754.X Invention Announce
Piece and preparation method.It includes concrete and glass fiber-reinforced polymer cage, and concrete, concrete surface have been poured in glass fiber-reinforced polymer cage
Connecting hole and hole for hoist are provided with, intensity of the present invention is high, in light weight, cost is low, antioxygen is corrosion-resistant, improves pipe to a certain extent
Piece service life, accelerate the construction speed in tunnel.But the liner structure has its specificity, is only applicable to shield tunnel
Precast assembly, the problems such as difficulty of construction is big, transport is inconvenient is had when constructing and use for bored tunnel, and manual operation is constructed
Precision does not reach requirement.
