Description
Technical field
A kind of bearing diagonal foundation pit enclosure structure is the utility model is related to, is a kind of combined type shaped steel, concrete specifically
Square pile bearing diagonal foundation pit enclosure structure, belongs to construction engineering technical field.
Background technology
In soft clay area, excavation pit need to carry out pattern foundation pit supporting structure, and soft clay area tradition foundation pit supporting method mainly has perfusion
Stake, SMW engineering methods, cement-soil wall etc..At present, for needed in bored concrete pile, SMW engineering methods set horizontal support caused by
The shortcomings of shoveling is inconvenient, the duration is longer, cost increase, has developed slip casting steel pipe diagonal brace combining structure.Specific method is using note
Slurry steel pipe bearing diagonal replaces horizontal support, can avoid using horizontal support, facility of cutting the earth, reduces the duration, reduces cost.
But this structure with oblique member, it is higher to the intensity requirement of steel pipe, when bearing diagonal length reach to a certain degree it
Afterwards, the intensity requirement of steel pipe often more difficult satisfaction, cost rise is also resulted in while the intensity of steel pipe is improved, while in soil
When hydrodynamic properties are poor, do not stop grouting and also form waste, result in the rise of cost.
The content of the invention
The utility model technical issues that need to address are：Existing bearing diagonal foundation pit enclosure structure, when bearing diagonal length
After reaching to a certain degree, the intensity requirement of steel pipe often more difficult satisfaction, also resulted in into while the intensity of steel pipe is improved
This rise, while when soil body mechanical property is poor, does not stop grouting and also form waste, result in the rise of cost.
The utility model takes following technical scheme：
A kind of combined type shaped steel, concrete square pile bearing diagonal foundation pit enclosure structure, including it is three-dimensional shaped steel, junction steel plate 2, mixed
Solidifying earthwork stake 3；It is coaxially connected with concrete square pile that the three-dimensional shaped steel passes through junction steel plate 2；The three-dimensional shaped steel
Upper end is fixedly connected with the capping beam 5 at the top of foundation pit enclosure stake 6.
Further, the height of junction steel plate 2 is located at the lower section of the bed course of proposed underground structure.
Further, the three-dimensional shaped steel is the H-shaped H profile steel 1 in cross section.
Further, the H profile steel 1 is provided with sealing piece 4.
Further, the sealing piece 4 is horizontally disposed.
Further, the outer profile size of the H profile steel 1 is equal with the length of side of the concrete square pile 3.
The beneficial effects of the utility model are：
1) foundation pit enclosure stake, H profile steel, concrete square pile is made to together form bearing diagonal supporting construction, more than foundation ditch bottom surface
H profile steel there is good resistance to compression, bending resistance and resistance to compression tropism energy, the concrete square pile below foundation ditch bottom surface can provide larger side
Frictional resistance and end resistance, make the utility model that there is preferable stability.
2) inclined support structure of two-part is cleverly used, while without slip casting, this design, which has, takes into account cost and strong
Degree considers of both requiring.
3) it is greatly reduced than the steel pipe inclined support structure of equality strength, cost；
4) situation when soil body mechanical property that is particularly suitable for use in is poor, without grouting, cost reduces, easy for construction.

Embodiment
The utility model is further illustrated with specific embodiment below in conjunction with the accompanying drawings.
Referring to Fig. 1-4, a kind of combined type shaped steel, concrete square pile bearing diagonal foundation pit enclosure structure, including three-dimensional shaped steel, company
Connect steel plate 2, concrete square pile 3；It is coaxially connected with concrete square pile that the three-dimensional shaped steel passes through junction steel plate 2；Institute
The capping beam 5 that three-dimensional shaped steel upper end is stated with the top of foundation pit enclosure stake 6 is fixedly connected, and plate size is according to concrete square pile and shaped steel
Model determines.
In this embodiment, it is located at the lower section of the bed course of proposed underground structure referring to Fig. 1, the height of junction steel plate 2.
In this embodiment, referring to Fig. 1, the three-dimensional shaped steel is the H-shaped H profile steel 1 in cross section.
In this embodiment, it is provided with sealing piece 4 referring to Fig. 1, the H profile steel 1.
In this embodiment, it is horizontally disposed referring to Fig. 1, the sealing piece 4.
In this embodiment, referring to Fig. 1, the length of side phase of the outer profile size of the H profile steel 1 and the concrete square pile 3
Deng.
During Specific construction, referring to Fig. 4, constructed according to following process：Construction foundation pit fender post, tilt press-in concrete
Square pile 3, the top of square pile 3 are welded to connect steel plate 2, and referring to Fig. 1, excavation of foundation pit forms shaped steel, concrete square pile tiltedly props up to after cheating bottom
Support foundation pit enclosure structure.
The fabricated structure makes foundation pit enclosure stake, H profile steel, concrete square pile together form bearing diagonal supporting construction, base
