Description
Technical field
The utility model is related to urban construction technical fields more particularly to a kind of pattern foundation pit supporting structure steel-pipe pile diaphragm wall to dock
Joint structure.
Background technology
It is deep with reference to different excavation of foundation pit in Base hole supporting technology field with the continuous progress of construction technology level
Degree, different surrounding enviroment conditions, alternative foundation pit support plan is more and more, and construction technology level is also advanced by leaps and bounds.
On the other hand, with the continuous propulsion of Process of Urbanization Construction process, more and more excavation of foundation pit are needed under overpass, high-voltage electricity
The inferior headroom of cable is restricted larger region and implements, such headroom confined condition, is selected to the scheme of zone similarity pattern foundation pit supporting structure
Type causes difficulty.
At present, in the Support of Foundation Pit Excavation scheme of clear height confined area, using it is more be cast-in-situ bored pile supporting, it is additional
High-pressure rotary-spray pile water stopping curtain.The program is permanent abandoned project, and overall cost is higher, easily causes the relatively billow of national economy
Take.Therefore, start to promote steel-pipe pile diaphragm wall foundation pit support plan in recent years, the program has both steel sheet pile foundation pit support plan and makes
Valency is relatively low, possesses the advantages that function of self waterproofing, while has the advantages that cast-in-situ bored pile rigidity is larger again, in addition, steel-pipe pile
The advantages of merogenesis is set, merogenesis splices is also equipped with, greatly improves its applicability to environmental condition.But steel-pipe pile pair
The mode of splicing is connect, will significantly influence overall stiffness, the deep pit monitor of steel-pipe pile diaphragm wall supporting construction.
The intensity for the steel pipe piling wall for ensureing splicing is designed, while there is the connector of comparable tensile capacity and shear resistance
Structure is a realistic problem in the field.
Those skilled in the art are directed to solving above-mentioned technical barrier.
Utility model content
In view of the drawbacks described above of the prior art, the technical purpose of the utility model is to provide a kind of pattern foundation pit supporting structure steel
Pile pile diaphragm wall banjo fixing butt jointing structure can be realized and steel-pipe pile diaphragm wall pattern foundation pit supporting structure is applicable under conditions of construction net height is limited
Scheme, and can ensure that the overall stiffness of steel-pipe pile diaphragm wall supporting construction, so as to ensure the safety of foundation pit.
To realize above-mentioned technical purpose, the utility model provides a kind of pattern foundation pit supporting structure steel-pipe pile diaphragm wall banjo fixing butt jointing
Structure, including steel-pipe pile diaphragm wall, the steel-pipe pile diaphragm wall includes several steel-pipe pile segments and steel sleeve, several steel pipes
It is welded between pile section section, the steel sleeve is sheathed on the connector between the steel-pipe pile segment Wai and is welded with the steel-pipe pile segment
It connects.
Further, several seamless steel pipes, institute are equipped on the steel-pipe pile segment tube wall of the upper and lower of the steel sleeve
It states and is arranged in pairs on steel-pipe pile segment of the seamless steel pipe above the steel sleeve and the steel-pipe pile segment below the steel sleeve,
It is connected between the seamless steel pipe arranged in pairs by split bolt.
Further, the seamless steel pipe is set close to the steel sleeve.
The beneficial effects of the utility model：
The utility model can make steel-pipe pile diaphragm wall determine merogenesis length according to construction net height environmental condition to adapt to not
Same construction net height condition, and the shear resistance of stitching portion supporting construction can be ensured by steel sleeve, and splicing can be passed through
Seamless steel pipe and split bolt at node ensure the tensile capacity of stitching portion supporting construction, improve steel under clear height confined condition
The overall stiffness of pile pile diaphragm wall supporting construction, it is ensured that the safety of steel-pipe pile diaphragm wall pattern foundation pit supporting structure has very strong practicality
Property.
