Abstract
The invention provides a supporting structure for controlling the stability of a foundation ditch. The supporting structure is characterized in that vertical supporting piles with the different lengths are arranged according to the conditions of a peripheral environment, a shape, a floor layer and the like of the foundation ditch; and the long and short supporting piles are distributed at intervals according to requirements to control the deformation of the foundation ditch, so that the stability and the safety of the foundation ditch are improved, materials are saved and the engineering construction cost is reduced.
Description
Technical field
The present invention relates to the ground foundation engineering technical field, the concrete support system structure that relates in a kind of base pit engineering.
Background technology
At present, draw in the base pit engineering of support system at the anchor that adopts, general construction sequence is the retaining wall of constructing first, then excavation pit carries out cable bolting again, and this work progress is fit in little foundation ditch, in large-scale deep foundation ditch, excavation pit occurs easily and cave in, enclosed structure distortion, the problems such as perhaps leak in the anchor cable construction process.
If the general soldier pile that adopts carries out supporting, in order to reach preferably supporting effect, then need soldier pile is squeezed into soil body deep layer, form long soldier pile, if but all soldier piles are long stake, then increase construction costs, bring very large cost burden.If but stake is long very short, then security performance is undesirable again.Can save the again supporting and protection structure of security performance composite demand of cost so the needs searching is a kind of.
Summary of the invention
Technical problem to be solved by this invention is, overcomes the problem that has pattern foundation pit supporting structure stability in the prior art, and a kind of supporting and protection structure of controlling base pit stability is provided.
Such in order to address the above problem technical scheme of the present invention:
A kind of supporting and protection structure of controlling base pit stability is provided with vertical soldier pile in the foundation pit supporting construction, vertical soldier pile is concrete pile or piling bar, it is characterized in that, vertical soldier pile is comprised of the length stake, and length stake interval arranges that long stake is longer more than 1 meter than stub.
Described length stake, in same support wall, length stake space is arranged.
Described length stake, stub are in same support wall, and the support wall outside or inboard arrange long stake.
Described length bottom is positioned at than hardpan, and the stub bottom is positioned at than Soft Soil Layer.
Described length stake diameter is identical or different.
Foundation pit side-wall is provided with the oblique stiffening pile that stretches into the soil body, and stiffening pile connects vertical soldier pile by waist rail.
Vertical soldier pile is bored pile or multi-shaft cement agitation pile interpolation shaped steel.
Foundation pit side-wall is provided with inner support and stiffening pile combining structure, and stiffening pile connects vertical soldier pile by waist rail, and inner supporting structure connects vertical soldier pile by enclosing purlin.
Foundation pit side-wall is provided with the oblique stiffening pile that stretches into the soil body, and stiffening pile connects vertical soldier pile by waist rail.
Beneficial effect: supporting and protection structure of the present invention, can carry out the large-scale foundation pit construction, supporting and protection structure is safe and reliable.Can greatly improve the safety that anchor draws support system integral body, reduce construction costs.
