Abstract
The utility model discloses a steel sheet pile and tubular pile combined foundation pit supporting structure, and relates to the technical field of geotechnical engineering, in particular to the technical field of steel sheet pile and tubular pile combined foundation pit supporting structures. The supporting structure comprises steel sheet piles which are used for water retainment of a foundation pit, and tubular piles which are used for improving the stiffness of the supporting structure, wherein a U-shaped fastener is arranged at each independent tail end of the steel sheet piles; a plurality of steel sheet piles are mutually connected through the U-shaped fasteners; and the tubular piles are arranged in the steel sheet piles. The utility model aims to provide a steel sheet pile and tubular pile combined foundation pit supporting structure which has a simple structure, is high in structural stiffness, has the functions of retaining soil and water, can be recycled, and is applicable to relatively large excavation depth.
Description
Technical field
The utility model relates to the technical field of geotechnical engineering, relates in particular to the technical field of a kind of steel sheet pile and pile tube combined foundation ditch support structure.
Background technology
Steel sheet pile has quick construction, and steel sheet pile can be pulled out after foundation pit construction finished, and is recycling, the characteristics such as better economy.But because the anti-side rigidity of steel sheet pile less is out of shape larger.Having relatively high expectations and dig in surrounding enviroment should be less in the dark larger base pit engineering.
Refer generally to Pretensioned spun concrete piles, several types is arranged, PC, PHC etc. is at aspects such as industrial and civilian construction, harbour, municipal administration, bridge, road and rail, hydraulic engineerings, in order to do foundation material, generally can use pile tube, pile tube has construction soon, and is good to geological adaptability, the characteristics such as economy.The shape of pile tube mainly is circular hollow pipe of cement, and it is wider that pile tube is used.The shortcoming of pile tube is that bending resistance is not high, generally uses less in base pit engineering.
Summary of the invention
The utility model purpose provides a kind of simple in structure, and the rigidity of structure is large, has gear native water stopping function, reusable edible concurrently, is applicable to the darker steel sheet pile of cutting depth and pile tube combined foundation ditch support structure.
A kind of steel sheet pile and pile tube combined foundation ditch support structure, comprise steel sheet pile for the foundation ditch dash, be used for improving the pile tube of supporting and protection structure rigidity, the independent end of each of described steel sheet pile arranges respectively the U-shaped fastener, interconnect by the U-shaped fastener between several steel sheet piles, pile tube is arranged in the inside of steel sheet pile.
U-shaped opening between adjacent two steel sheet piles of the utility model is towards the opposite; Pile tube can be high-strength prestressed concrete pipe pile (PHC pile tube), prefabricated high-strength concrete thin steel pipe pile (TSC pile tube) or steel pipe pile.
The utility model adopts technique scheme, and compared with prior art have following advantage: the present invention adopts steel sheet pile and pile tube combined foundation ditch support structure, can give full play to both advantages.Have the rigidity of structure large, stagnant water effect is good, flexible operation, the advantages such as convenient recovery.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the technical solution of the utility model is elaborated:
As shown in Figure 1, a kind of steel sheet pile and pile tube combined foundation ditch support structure, comprise steel sheet pile 1 for the foundation ditch dash, be used for improving the pile tube 2 of supporting and protection structure rigidity, the independent end of each of described steel sheet pile 1 arranges respectively U-shaped fastener 3, interconnect by U-shaped fastener 3 between several steel pipe piles 1, pile tube 2 is arranged in the inside of steel pipe pile 1.
As shown in Figure 1, the U-shaped opening between adjacent two steel pipe piles 1 of the utility model is towards the opposite.Pile tube of the present utility model can be high-strength prestressed concrete pipe pile (PHC pile tube), prefabricated high-strength concrete thin steel pipe pile (TSC pile tube) or steel pipe pile.
Job practices based on steel sheet pile of the present utility model and pile tube combined foundation ditch support structure may further comprise the steps:
The first step: according to site condition and computational analysis, determine steel sheet pile 1 model, the stake long, determine pile tube 2 model, the stake long, pile spacing;
Second step: construction pile tube 2;
The 3rd step: construction steel sheet pile 1;
The 4th step: excavation pit, Construction Support system;
The 5th step: to clearing up at the bottom of the Foundation Pit, flattening, build bed course, construction base plate and agent structure;
The 6th step: backfill, extract according to circumstances steel sheet pile 1.
That steel sheet pile in the utility model can adopt is U-shaped, Z-type, emit shaped steel plate pile or with the combination form patterns such as H shaped steel, steel pipe, pile tube can be the patterns such as high-strength prestressed concrete pipe pile (PHC pile tube), prefabricated high-strength concrete thin steel pipe pile (TSC pile tube) or steel pipe pile.
Claims (2)
1. a steel sheet pile and pile tube combined foundation ditch support structure, it is characterized in that comprising steel sheet pile (1) for the foundation ditch dash, be used for improving the pile tube (2) of supporting and protection structure rigidity, each independent end of described steel sheet pile (1) arranges respectively U-shaped fastener (3), interconnect by U-shaped fastener (3) between several steel pipe piles (1), pile tube (2) is arranged in the inside of steel sheet pile (1).
2. steel sheet pile according to claim 1 and pile tube combined foundation ditch support structure is characterized in that the U-shaped opening between above-mentioned adjacent two steel sheet piles (1) is towards the opposite.
