Description
Technical field
The present invention relates to both wired jacking bridge and culvert technical field of construction, in particular to a kind of both wired jacking construction of prevention work side
Method.
Background technology
The frame construction of existing railway jacking at present method (as shown in figures 1-4) is on the premise of ground is firm, pre-
Frame culvert 23 in place, in the case where not cutting off traffic, is pushed into both by the pushing tow of frame culvert 23 made with high-power jack group
Have under railway line 22.However, suitable for the relatively small bridges and culverts in across footpath, aperture when technology origin, and under Modern Traffic
Road width is more and more wider, and the aperture of frame culvert 23 the more is done the more big, continue to continue to use prior art can cause project scale, difficulty of construction,
Construction risk etc. is increasing.Particularly construction temporary project amount is big, in the case of complex procedures, can bring bigger construction
Difficulty and construction risk.
The content of the invention
Present invention aim to provide one kind to reduce project scale, and can reduces difficulty of construction, construction risk
Both wired jacking protection construction method.
To achieve the above object, a kind of both wired jacking protection construction method designed by the present invention, comprises the following steps：

Embodiment
The present invention is described in further detail with specific embodiment below in conjunction with the accompanying drawings.
As shown in Fig. 5~12, a kind of both wired jacking protection construction method of the present embodiment, comprise the following steps：
1) according to the physical dimension of bridges and culverts, place is selected to distinguish prefabricated abutment wall 1 and vault 2 beyond circuit safe distance；
2) abutment wall cutting shoe device 3, vault cutting shoe device 4 are combined into using steel plate welding, in the front end of abutment wall 1 and vault 2
Abutment wall cutting shoe device 3, vault cutting shoe device 4 are installed respectively；
3) the jacking order to abutment wall 1, vault 2 is selected according to actual conditions, is divided into two kinds of situations：
In the ban to the jacking operation of abutment wall 1, after to 2 jacking operation of vault when, specific method is：According to the embedded depth of abutment wall 1
Soil box is excavated on the outside of bridges and culverts, slideway is laid in bottom land, and incremental launching device is set in one end away from bridges and culverts of slideway, then by abutment wall
1 lifting is put into slideway, and the one end of abutment wall 1 with abutment wall cutting shoe device 3 adjusts the placement location of abutment wall 1 to protect towards bridges and culverts
Card pushing tow is traveling on desired trajectory, then applies jacking active force to the one end of abutment wall 1 away from bridges and culverts by incremental launching device, no
Disconnected jacking, spoir move in circles until pushing tow is to setting position, and that the soil body caves in such as be present can use mud off or other
Feasible method is protected, while existing trajectory, roadbed etc. are monitored by design detection requirement, holds be advanced in time
Situation in journey, the especially bad symptom of a trend, tackled by the early warning scheme pre-established, one of abutment wall 1 is carried out down after the completion of pushing tow
Jacking operation, until completing the jacking operation of all abutment walls 1；After the completion of the jacking of abutment wall 1, to the jacking operation of vault 2
Specially：Supporting apparatus 5 is set in the both sides of vault 2, and incremental launching device, arch are set in the one end of vault 2 away from bridges and culverts

Apply jacking active force, one side jacking forms the unearthed passage 24 of vault while digging, and the channel width is much smaller than vault width, constantly
Jacking, spoir move in circles up to pushing tow to setting position；
In the ban to the jacking operation of vault 2, after to 1 jacking operation of abutment wall when, specific method is：According to the height of bridges and culverts,
Soil box is excavated in corresponding height position on the outside of bridges and culverts, lays slideway in bottom land, and set pushing tow to set in the one end of slideway away from bridges and culverts
It is standby, then the lifting of vault 2 is put into slideway, the one end of vault 2 with vault cutting shoe device 4 then passes through pushing tow towards bridges and culverts
Equipment applies jacking active force to the one end of vault 2 away from bridges and culverts, and continuous jacking, spoir move in circles up to pushing tow to setting position
Put；After the completion of the jacking of vault 2, it is specially to the jacking operation of abutment wall 1：Opened according to the embedded depth of abutment wall 1 on the outside of bridges and culverts
Shoveling groove, slideway is laid in bottom land, and incremental launching device is set in the one end of slideway away from bridges and culverts, then the lifting of abutment wall 1 is put into cunning
In road, for the top end face of abutment wall 1 with the bottom face of vault 2 on same horizontal plane, abutment wall 1 carries the one of abutment wall cutting shoe device 3
End then applies jacking active force, continuous jacking, spoir by incremental launching device towards bridges and culverts to the one end of abutment wall 1 away from bridges and culverts
Move in circles until pushing tow arrives setting position, use after the completion of pushing tow identical push construction method to carry out down one abutment wall 1
Jacking operation, until completing the jacking operation of all abutment walls 1.
4) after the completion of jacking operation, abutment wall cutting shoe device 3 and vault cutting shoe device 4 are dismantled respectively, complete both wired jackings
Construction of prevention work.
In implementation process, the sequencing of abutment wall 1 and the progress jacking construction of vault 2 can be exchanged, you can first to carry out
The jacking operation of abutment wall 1, it is rear to carry out the jacking operation of vault 2；The jacking operation of vault 2 can also be first carried out, it is rear to carry out the jacking of abutment wall 1 work
Industry.Abutment wall 1 and vault 2 are constantly unearthed, constantly advanced, in order to ensure not disturbing existing subgrade soils during jacking moves ahead
Body, it can push up more, can not dig more.When ground carrier strip part is preferable, can using abutment wall 1 now and vault 2 as permanent structure,
As long as then cut out soil body construction road or the circuit below top plate；In abutment wall 1, vault if also other permanent structures
If continuing construction further part engineering ratio under 2 protection has the problem of underground water, a U groove structure can be done.
As shown in Figs. 13 and 14, abutment wall cutting shoe device 3 include be bonded with the jacking end face of abutment wall 1 end plate 3.1, be arranged on end
