Description

Pipe pile composite foundation
Technical field
The utility model relates to build composite foundation, especially a kind of pipe pile composite foundation.
Background technique
At present generally there is foundation treatment mode in specification: CFG pile composite foundation, cement mixing pile composite foundation, rigid pile Composite foundation.These foundation treatment modes all have the shortcomings that one it is common: time-consuming too long, cost of labor accounting is too big, is difficult to Guarantee pile quality.Present cost of labor proportion in entire project cost alreadys exceed 30%, but also on continuing Rise.
Wherein, CFG, every stake machine can only make a call to 6 ~ 8 daily for cement mixing pile etc., and CFG, cement mixing pile beats Foundation trench could be excavated after at least waiting 28 days after complete stake, time-consuming, greatly improves building cost.
Utility model content
The purpose of this utility model is to provide a kind of short construction period, reliable in quality, easy for construction, the economic effect of raising Benefit effectively improves the pipe pile composite foundation of foundation bearing capacity, and to overcome, common composite foundation time-consuming is too long, cost of labor accounting Too greatly, it is difficult to ensure the disadvantages of pile quality.
Purpose of the utility model is realized as follows:
A kind of pipe pile composite foundation, including lower layer and upper layer, it is characterised in that: the lower layer is prefabricated tubular pile layer, upper layer For mattress layer, it is spaced from each other between adjacent prefabricated tubular pile in prefabricated tubular pile layer;The prefabricated tubular pile top closure, the mattress Layer is mixed by sandstone, and for mattress layer place mat on ground and prefabricated tubular pile top surface, mattress layer area coverage is greater than prefabricated tubular pile Location.When design, stake top absolute altitude it is 300 ~ 400mm(lower than sole plate bottom absolute altitude because mattress layer with a thickness of 200 ~ 300mm, plain concrete cushion layer is with a thickness of 100mm).
The purpose of this utility model can also be solved using following technical measures:
As more specific scheme, distance is the 3.5 to 4.5 of prefabricated tubular pile diameter between the adjacent prefabricated tubular pile Times.Same building monomer ground can squeeze into more prefabricated tubular piles, use weldering between two prefabricated tubular piles up and down of same position It connects in succession.Specific stake is long, stake diameter, stake spacing can carry out appropriately configured according to the calculated result of disparity items, and stake top absolute altitude compares base Plinth bottom plate bottom absolute altitude low 300 to 400mm.
As further embodiment, the prefabricated tubular pile top is equipped with sealing plate, and sealing plate closes prefabricated tubular pile top nozzle. The top of prefabricated tubular pile carries steel ring, and sealing plate uses the steel plate equal with prefabricated tubular pile diameter, the steel ring of steel plate and prefabricated tubular pile Firm welding.
Alternatively, the prefabricated tubular pile top is by filling sandwich layer closing.When stake top needs to cut stake, this side is taken Formula is by prefabricated tubular pile top closure.
The corresponding sandwich layer that fills in the prefabricated tubular pile inner cavity is equipped with sealing plate, and sealing plate seals the position of certain altitude in prefabricated tubular pile It closes.
The filling sandwich layer is C30 microdilatancy pea gravel concreten layer, with a thickness of 500mm.
As further embodiment, the mattress layer with a thickness of 200mm to 300mm.
The mattress layer is coarse sand, middle sand, macadam gradating sandstone, and the partial size of rubble is less than or equal to 30mm, and mattress layer rams Degree of filling out (ratio of mattress layer thickness and virtual resurfacing thickness after compacting) is less than or equal to 0.9.Rubble cannot use cobble.
Plain concrete cushion layer and sole plate are successively arranged on the mattress layer, plain concrete cushion layer is located at mattress layer area Within the scope of.
The mattress layer periphery has more 400mm or more than plain concrete cushion layer.
The beneficial effects of the utility model are as follows:
(1) such pipe pile composite foundation uses prefabricated tubular pile instead of CFG or cement mixing pile, also, to prefabricated pipe The top of stake is closed, and saving duration, pile quality are guaranteed, meanwhile, and it is more more economical than common pipe pile foundation, more square Just it constructs, is more more economical than common pipe pile foundation, can speed up the work, save a large amount of durations, to generate great economy Benefit;
(2) prefabricated tubular pile pile quality used by such pipe pile composite foundation is secure, because tubular pole is finished peg, Factory is directly prefabricated;
(3) prefabricated tubular pile used by such pipe pile composite foundation is more more economical than common pipe pile foundation, because than general Logical pile foundation, which eliminates, to be anchored into cushion cap or sole plate reinforcing bar, eliminates core grouted concrete;
(4) such pipe pile composite foundation can once excavate in place, not need brick mold, facilitate construction;
(5) such pipe pile composite foundation is suitable for the basement process of various types of multilayers or skyscraper (as long as suitable The soil property for closing pile foundation construction is all right).
Detailed description of the invention
Fig. 1 is an embodiment of the present invention schematic cross-sectional view.
Fig. 2 is to connect enlarged structure schematic diagram in Fig. 1 at the top of tubular pole.
Fig. 3 is to connect enlarged structure schematic diagram in the utility model at the top of another embodiment tubular pole.
Specific embodiment
The utility model is further described with reference to the accompanying drawings and embodiments.
Embodiment one, referring to figure 1 and figure 2, a kind of pipe pile composite foundation, including lower layer and upper layer, the lower layer be Prefabricated tubular pile layer, upper layer are mattress layer 4, are spaced from each other in prefabricated tubular pile layer between adjacent prefabricated tubular pile 1;The prefabricated tubular pile 1 top closure, the mattress layer 4 are mixed by sandstone, and 4 place mat of mattress layer is on 1 top surface of ground 3 and prefabricated tubular pile, mattress 4 area coverage of layer are greater than 1 location of prefabricated tubular pile.
Distance is 3.5 to 4.5 times of 1 diameter d of prefabricated tubular pile between the adjacent prefabricated tubular pile 1.
