Description
Technical field
The present invention relates to building support technology field, in particular to the support system for Metro station excavation end
System and method for supporting.
Background technology
At present in city track traffic engineering, Open Cut Method (or half cover and cut method) station pit widely uses branch
The supporting type of fender pile (diaphragm wall)+inner support.Metro station excavation is generally thin-and-long, and Central Standard section typically uses allotment
Support typically uses diagonal brace to support supporting, two ends end shield well scope.At present, the setting of end diagonal brace mainly has two kinds of sides
Formula, one kind is that, using cast-in-situ steel reinforced concrete waist rail+armored concrete bearing diagonal combination, second is to use cast in place reinforced bar coagulation
Native waist rail+steel pipe bearing diagonal combination.The common feature of both the above method for supporting is provided with preferable globality and larger
The deformation produced in support rigidity, the stabilization and control Excavation Process beneficial to foundation ditch, protection foundation ditch periphery construction of structures etc.,
But it is simultaneously there is also protruding very much the drawbacks of, main as follows：
(1) reinforced concrete support structure is employed, waist rail and inner support belong to temporary structure, using reinforced concrete structure
It is uneconomical.
(2) mould needs to apply ground mould before building reinforced concrete waist rail or support, and need to install reinforcing bar and vertical side form, phase of constructing
To cumbersome.
(3) mould builds reinforced concrete waist rail or the support duration is longer, and need to conserve that reach can be further after design strength
Excavation pit；And the later stage removes waist rail and supports also troublesome and spend time, the progress of integrated engineering is often restricted.This is on ground
That is embodied in iron construction is particularly evident：In the construction of whole subway line, the interval construction of shield often builds work to whole
Control action from phase, and the construction that originates and receive of shield is typically chosen end progress AT STATION, therefore the construction of station end
Often become the key node of duration control.
Above-mentioned discussion shows that the traditional support form of current foundation ditch corner (particularly subway station shield well position) is present
The construction series of problems such as cumbersome, long in time limit, less economical.
The content of the invention
In order to overcome the deficiencies in the prior art, the invention provides the support system and branch for Metro station excavation end
Support method.Specifically, its technical scheme is as follows：
A kind of support system for Metro station excavation end, including waist rail, bracket and support member, the one of the waist rail
Side is removably secured or is resisted against the medial surface of support pile or diaphram wall, and the bracket is arranged on the another of the waist rail
Between side and the support member, the bracket is obliquely installed relative to the waist rail, and fixation connects respectively at the two ends of the bracket
Connect the waist rail and the support member.
As the improvement to technical scheme, the waist rail includes several backbars for splicing setting side by side, the supporting
Two edges of a wing of beam are each provided with a panel, and each backbar is fixed together by the panel.
As the improvement to technical scheme, backbar is I-shape construction.
As the improvement to technical scheme, in the waist rail, the quantity of the backbar is two.
As the improvement to technical scheme, the waist rail, the bracket, backbar and the panel are steel material.
As the improvement to technical scheme, the support member is tubular structure.
As the improvement to technical scheme, the bracket is by the first connecting plate, the second connecting plate, the 3rd connecting plate, the
The hollow structure that four connecting plates, the 5th connecting plate, the 6th connecting plate are combined, the horizontal profile of the bracket is triangle knot
Structure, the vertical cross section of the bracket is " day " font structure.
As the improvement to technical scheme, the waist rail is axially spaced to be provided with several stiffeners.
As the improvement to technical scheme, the support member is coaxially disposed with the bracket.
A kind of method for supporting for Metro station excavation end, it is used for subway using described in foregoing either a program
Stand the support system of foundation ditch end, operate according to the following steps：
S1：Construction foundation pit support pile or diaphram wall；
S2：The side of waist rail is removably secured or is resisted against the inner side of the support pile or the diaphram wall
Face；
S3：The side of bracket and the opposite side of the waist rail are fixed, and the bracket is tilted relative to the waist rail
Set；
S4：Support member is fixedly attached to the opposite side of the bracket, and applies pre-applied force.
The present invention at least has the advantages that：
According to the support system and method for supporting provided by the present invention for Metro station excavation end, including waist rail, ox
Leg and support member, the side of waist rail are removably secured or are resisted against the medial surface of support pile or diaphram wall, and bracket is set
Between the opposite side and support member of waist rail, bracket is obliquely installed relative to waist rail, and the two ends of bracket are respectively fixedly connected with waist
Beam and support member.
This support system and method for supporting use reusable structural elements, waist rail, bracket and support member
Lifted in being transported to scene after factory process, it is easy with quick construction, and the advantages of recovery is used is repeated, both it can ensure that
Deep pit monitor, can save resource again, while install convenient, can greatly save the duration, advantage is notable.
