Description
Technical field
The invention belongs to city underground engineering technical fields, and in particular to a kind of city Shallow tunnel with large cross-section using pre-
The inverse-T-shaped excavation method in system support section of jurisdiction and temporary support structure.
Background technique
With the development of the city, surface road is no longer satisfied growing vehicular traffic, has only and builds tube
Road is alleviated.How big in traffic pressure, ground space is narrow, the Downtown of surrounding enviroment complexity, safe and efficient to repair
Shallow tunnel with large cross-section is built, selects suitable excavation method particularly critical.There are benching tunnelling method, CD at present for excavating large cross-section tunnel
The excavation methods such as method, CRD method, two side-wall pilot tunnel, they respectively have an advantage and disadvantage, for example the construction of benching tunnelling method, CD method is more quick, still
In city, there are security risks in shallow embedding and stratum poor location；And CRD method and two side-wall pilot tunnel divide face is excavated
Portion is more, and construction space is smaller, and gib is constructed, and dismounting amount is larger, and construction efficiency reduces very much；Two side-wall pilot tunnel construction
Safety, but speed is slower, higher cost.In addition to this, above-mentioned existing engineering method especially will when building large cross-section tunnel
The interim vertical median septum of construction or interim inverted arch, when excavation supporting, shaped steel arch is installed in gib, hangs steel mesh, and injection is mixed
Solidifying soil is constructed, and also temporary support is all removed before later-stage secondary lining construction, not only construction efficiency is low, while causing tunnel
Road hole environment pollution, lot of materials waste, is not suitable for green construction section material, energy-efficient theory.
Summary of the invention
The present invention to solve the deficiencies in the prior art, in conjunction with city Shallow tunnel with large cross-section construction characteristic, is different from existing
Excavation method, innovation propose a kind of city Shallow tunnel with large cross-section use the inverse-T-shaped excavation method in precast support section of jurisdiction with
And temporary support structure.
The present invention is achieved by the following technical solutions: a kind of inverse-T-shaped excavation of city Shallow tunnel with large cross-section faces
When support construction, including prefabricated interim vertical supporting section of jurisdiction and interim cross-brace section of jurisdiction, the median septum of upper left step is by facing
When vertical supporting pipe sheet assembling set up, the inverted arch of upper left step is set up by interim cross-brace pipe sheet assembling；Upper right
The inverted arch of step is set up by interim cross-brace pipe sheet assembling；Interim vertical supporting section of jurisdiction is equipped with injected hole.
Assembly is bolted in the assembly of the interim vertical supporting section of jurisdiction and interim cross-brace section of jurisdiction.
2 injected holes are equipped between the interim vertical supporting section of jurisdiction connection bolt, injected hole is at a distance from bolt
30cm。
The width of the interim vertical supporting section of jurisdiction and interim cross-brace section of jurisdiction is 1.5m, with a thickness of 20cm.
The invention also includes a kind of city Shallow tunnel with large cross-section to use the inverse-T-shaped excavation method in precast support section of jurisdiction, packet
Include following steps:
(1) upper left bench excavation: first carrying out advance support, then excavate, and carries out preliminary bracing construction, and assembling is prefabricated
Interim vertical supporting section of jurisdiction and interim cross-brace section of jurisdiction are set up into interval wall construction with interim vertical supporting pipe sheet assembling, are used
Interim cross-brace pipe sheet assembling is set up into inverted arch structure；
(2) upper right bench excavation: first carrying out advance support, then excavate, and carries out preliminary bracing construction, and assembling is prefabricated
Interim cross-brace section of jurisdiction, is set up with interim cross-brace pipe sheet assembling into inverted arch structure；
(3) get out of a predicament or an embarrassing situation excavation: excavation of getting out of a predicament or an embarrassing situation, tunnel landing, construction tunnel inverted arch preliminary bracing form loopful closure；
(4) secondary lining inverted arch is constructed: after the completion of getting out of a predicament or an embarrassing situation construction, in the inverted arch that interim cross-brace pipe sheet assembling is set up
It constructs in time under structure secondary lining inverted arch；
(5) secondary lining side and roof arch is constructed: after the completion of the construction of Tunnel Second Lining inverted arch, removing the interim vertical of above-mentioned steps
Section of jurisdiction and interim cross-brace section of jurisdiction are supported, the lining construction of secondary lining side and roof arch two is carried out；
(6) circulation is excavated: utilizing the interim vertical supporting section of jurisdiction removed and interim cross-brace section of jurisdiction into next excavation branch
Shield circulation.
Beneficial effects of the present invention:
One, it takes interim vertical supporting not bottomed, is closed with interim cross-brace, forms the inverse-T-shaped excavation method of innovation,
Top bar is divided into upper left step and two step of upper right step is excavated, is reduced to the disposable perturbation area of the face soil body.This hair
Bright engineering method step is simple, and strong operability is saved the area, and economic benefit and social benefit are significant.
Two, a close ring is just formed after the completion of top bar is excavated, the inverted arch that interim cross-brace section of jurisdiction splicing is set up subtracts
The clearance convergence in tunnel is lacked, the median septum that interim vertical supporting section of jurisdiction splicing is set up reduces tunnel vault sedimentation, leaves office
Rank does not set up interim perpendicular support, not only increases efficiency while guaranteeing safe, has also speeded up tunnel landing and loopful closure
Time, while the construction speed of Tunnel Second Lining inverted arch can be accelerated, reduce tunnel safety hidden danger.
Three, interim cross-brace section of jurisdiction and interim vertical supporting section of jurisdiction can be recycled, and have saved a large amount of raw material, reached
Safe and efficient, green, factorial construction purpose is arrived.
Four, the present invention increases in the case where guarantee preliminary bracing safe stress and excavates space, reduce gib
Construction and the workload removed, had not only improved working efficiency but also had saved construction cost.Compared with the temporary support of existing site operation
Compared with, reduce construction time and concrete strength curing time, it is i.e. force-applied after prefabricated temporary support installation, reduce injection
Curing time needed for concrete strength is up to standard avoids the problem of sedimentation is with convergent deformation after tunnel excavation, especially interim cross
It to support (inverted arch), can pass through immediately after having set up, as construction road, machinery can pass through immediately, and existing conventional branch
Shield, can pass after waiting the concrete curing time to meet intensity requirement.The present invention reduces on-site construction times, reduce
Construction pollution in tunnel.
