Description
Technical field
The utility model relates to pile foundation, is specifically related to a kind of intersecting parallels campshed basis.
Background technology
Campshed basis is the building pile basis structure of arranging composition with certain type by queue-type, and it is large with bearing capacity, good stability, sedimentation value are little, can adapt to the features such as various geological conditionss and load situation and be widely applied in building, the hydraulic engineerings such as highrise building, large-sized workshop, water conservancy and hydropower hinge, railway engineering, highway engineering, bridge engineering, offshore production platform, nuclear power station.
Campshed basis is specifically made up of jointly some foundation piles and the cushion cap that is connected in stake top, is used to the building on it that enough bearing capacities are provided; The load of building passes to ground by its below pile foundation, the frictional resistance that wherein vertical load is generally produced by the resistance of stake substratum and pile body side and the soil body supports, and that is to say that pile foundation is broadly divided into two kinds of end bearing pile and friction piles by Force principle.
As shown in Figure 1, it is hard soil layer or rock stratum that end bearing pile 1 reaches hard formation 3(through Soft Soil Layer 2), the superstructure load of end bearing pile 1 is mainly born by hard formation 3 resistances; When construction, taking pile penetration as main, pile top enters bearing stratum depth or pile top absolute altitude can be for referencial use.
As shown in Figure 2,4 of friction piles are arranged in Soft Soil Layer 2 completely, by its pile body by compacted Soft Soil Layer 2 reality, to improve native compactness and supporting capacity, the load of its superstructure is born jointly by the frictional resistance between end-resistance and pile body side and Soft Soil Layer 2, when construction, to control pile top design elevation as main, pile penetration can be for referencial use.
The current existing problem in campshed basis is: 1. can provide enough bearing capacities in order to ensure it to upper building, very big for the length requirement of pile body, the pressure that this has not only increased construction cost aspect, has also improved the difficulty of construction; 2. at adjacent foundation pile top, coupling beam is set conventionally and interconnects, to increase the resistance to overturning on campshed basis, but its effect is very limited, and cost is higher, affects the construction of upper building.
Summary of the invention
The purpose of this utility model is according to above-mentioned the deficiencies in the prior art part, a kind of intersecting parallels campshed basis is provided, this campshed basis by each adjacent single pile bottom and middle part twice stake crossbeam is set realizes and be interconnected to constitute one, to provide much larger than the pressure-bearing cross section on conventional campshed basis, improve its overall stress-bearing capability.
The utility model object realizes and being completed by following technical scheme:
A kind of intersecting parallels campshed basis, this campshed basis is rearranged by some single piles that vertically go deep in the soil body, it is characterized in that being positioned between described single pile adjacent in described campshed basis pile body bottom and medium position interconnects by twice stake crossbeam respectively, described stake crossbeam and described single pile are structure as a whole, and make described campshed basis be intersecting parallels stake shape.
Described stake crossbeam diameter is identical with described single pile diameter.
Described single pile pile body and described stake crossbeam intersection location place have footing, and described footing and described crossbeam are perpendicular, and described footing and described single pile axis perpendicular.
The length of described footing is at least the twice of described single pile diameter.
Described footing is strip.
Described footing semicircular in shape shape.
Described semicircular radius is at least the twice of described single pile diameter.
The utility model has the advantages that, intersecting parallels campshed foundation structure is simple, a stake crossbeam that connects adjacent single pile by setting up at campshed foundation bottom and middle part makes it to form stable overall structure, and by set up footing on each single pile, to increase the overall pressure-bearing cross section on campshed basis, effectively improve overall bearing capacity and the resistance to capsizing of pile group, in addition, compared with having the conventional campshed basis of equal bearing capacity, its single pile length can shorten greatly.
