Description
Technical field
The utility model relates to the support systems in a kind of foundation pit, are that a kind of active control foundation pit is displaced specifically
Support system belongs to base pit engineering technical field.
Background technique
Excavation of foundation pit can cause the sedimentation and displacement of surrounding formations, to influence the safety of adjacent subway tunnel, building.
The type of existing support system and there are the problem of it is as follows：
1, concrete support system, the high stability of this system, but can not be carried out using measure after being subjected to displacement
Remedy, thus it can not active control building enclosure displacement；In addition, concrete support system is mostly statically indeterminate structure, coagulation
For native component by power that is curved, pressing, cut, turn round, stress condition is extremely complex, and jack is added such as in the component of internal system and applies
Axle power can generate secondary stress to whole system, and member stress and the value for easily leading to concrete are different, it is difficult to meet degree of safety
Requirement.
2, servo-type bracing members system, this system connect the mode of a bracing members using a jack, are
A kind of structure of strip can not be applicable in the foundation pit of complicated shape though can control the displacement of building enclosure.This
Outside, the case where the case where large-scale excavation excavates, the span of bracing members is larger, is easy to appear unstability, once unstability, it may appear that even
Lock failure reaction, increases the risk of foundation pit.
3, bracing members and concrete support combined system, common form are that servo-type bracing members combine concrete purlin,
But this still can not be solved the disadvantage that described in the 2nd article；Another common form is by the inside structure in concrete support
Part is substituted for servo-type bracing members, but concrete system statically indeterminate structure can be to body when servo-type bracing members apply axle power
System generates secondary stress, and the degree of safety of system weakens, and foundation pit risk increases.
In addition, when the prior art copes with large-scale excavation, it also can be using the method for foundation pit point hole construction, by big face in construction
Product foundation pit be divided into multiple small foundation pits carry out excavate and supporting, this scheme need to construct multiple points hole between dividing wall, greatly
Construction period and cost are increased greatly.
In conclusion the prior art cannot be considered in terms of the advantage of active control displacement and stable system, the construction period is long, cost
It is high.
