Description
Technical field
The present invention relates to support construction technical fields, more specifically to based on coercion underground continuous wall structure
Assembled support construction technique.
Background technique
Assembled supporting construction is to be assembled at the scene based on molding prefabricated components by various technological means
Supporting construction.Compared with conventional supporting means, which has the characteristics that low cost, short time limit, quality are easily controllable, from
And greatly reduce energy consumption, reduce building waste, have higher social and economic benefits and environmental-protection function, currently, in the market compared with
Have for mature assembled supporting construction: prefabricated pile, coercion underground continuous wall structure, prestressing force fish belly sill support construction, tool
Formula combines inner support etc., and prefabricated pile is as foundation pit supporting construction in use, mainly using conventional construction of prefabricated piles method, such as
Static pressure or hammer-impact construction, can also use borrowing cement mixing method, and TRD stirs wall or the stirring of CSM Double-wheel milling shape within the walls
At continuous soil cement composite supporting construction.When prestressing force prefabricated pile is used for supporting construction, it should be noted that prevent prestressing force prefabricated pile
Brittle break occurs and ensures the construction quality of connector.
Existing supporting construction is drawn using the support of short column diaphragm plate, the support of interim retaining wall, batter post support, anchor mostly
Method for protecting support, the scope of application very littles of these supporting construction such as support only can be suitably used for cutting depth less than seven meters, and without special
It is required that foundation pit, and ten meters are greater than for cutting depth, and the foundation pit one of Nearby Structure, critical facility within cutting depth
As using part supporting construction and foundation structure unification form of construction work, mostly using diaphram wall as supporting construction
The construction work of main body, but this construction work using diaphram wall as supporting construction main body is in some special geology items
Under part, such as very soft muck soil, the alluvium containing erratic boulder and superhard rock, difficulty of construction is very big, is not available, and easily go out
Existing adjacent wall section cannot be aligned and the problem of leak.
1. technical problems to be solved
Aiming at the problems existing in the prior art, the purpose of the present invention is to provide based on coercion underground continuous wall structure
Assembled support construction technique, coercion underground continuous wall plate may be implemented in it, is supported, is convenient for using assembled supporting construction
The form of construction work for using diaphram wall to engage as supporting construction and foundation structure, while by special circulating mud, it supports
The anti-soil lateral pressure and water pressure acted on cell wall, prevents cell wall from collapsing and peeling off, while preventing Groundwater infiltration, recycles
Mud forms one layer of very low mudcake of water penetration on cell wall, can prevent cell wall from peeling off, after the completion of the side slip casting of toe of wall wall, circulation
Under the pressure of mud after forming, at solid state, the junction gap of underground continuous wall plate is filled up, while in forming pressure
Under, the moisture of silicon substrate growth bead consumption gap fixes circulating mud adhesion.
