Method.
Background technique
In recent years, the features such as shield method is good with its construction quality, safe and small to surrounding environment influence is in engineering construction
It is widely applied.There are the construction situation of tunnel lateral opening in shield-tunneling construction, including two single track line tunnels it
Between Freezing Method for Cross-passage Construction and ventilating shaft construct situations such as, cut and cover method, soil stabilization subsurface excavation method, pipe shed method can be used in construction method
With small-sized shield method etc..Its middle-size and small-size shield method is excavated using mechanical, has not only solved small space originating issue, but also can be compared with
Easily Freezing Method for Cross-passage Construction axis is controlled.But in digging process, shield machine can apply pressure to tunnel, especially
It is the undefined structure of lateral openings shape, is easy to generate tunnel duct piece additional deformation, therefore in order to ensure excavating the pipe at position
Piece safety, it usually needs excavating position local setting temporary support protective stent.
The way of existing conventional support protective stent is at the construction field (site), by the length that design needs, to be connect by flange
Long splicing is set up, and two jack of pressurizer are put at segmented head pressurization after meeting the requirements with gantry crane and are positioned by inspection
Pressurization stops pressurization after reaching the estimated axle power of design, then gad is squeezed into segmented head preformed hole, and then decompression is laid down very heavy
Top, needs sequentially to carry out dismounting work to bracing members after construction.Conventional support protective stent has the disadvantage that (1)
Dismounting is inconvenient in tunnel small space, and especially the gad of segmented head bolt portion is not easy to remove under pressurized condition；(2) in distich
Network channel can not provide recoil well when laterally being constructed for shield machine, and section of jurisdiction unbalance stress easily causes deformation；(3) nothing
Method is recycled；(4) adjustment of work progress axial force of the supports is difficult.
