Abstract
The utility model relates to a building foundation, in particular to a precast pile composite foundation which comprises precast pile units evenly distributed in a matrix, a cushion layer and a hardened foundation face, wherein the cushion layer is evenly laid on the precast pile units. Each precast pile unit comprises a plurality of reinforcing bodies and precast pile bearing tables arranged on the tops of the reinforcing bodies, wherein the reinforcing bodies are vertically arranged in a soil layer in a matrix, and each reinforcing body comprises a reinforcing main body and load distribution ribs surrounding the reinforcing main body. The precast pile composite foundation is reasonable in structure design, high in overall bearing ability and compact in soil layer structure, and acting force between the precast piles is strong.
Description
Technical field
The utility model relates to a kind of building lot, is specifically related to a kind of preformed pile composite foundation.
Background technology
Composite foundation originates from the sixties in 20th century, owing to significantly improving the bearing capacity of ground, reduce foundation settlement, and effectively suppress this feature of foundation soil body lateral deformation and become a kind of more satisfactory Soft Ground mode, be worldwide all used widely.Along with the deep and scientific and technical development of people to its theory analysis, the kind of composite foundation and construction machinery are more and more.
What is composite foundation for, has different views in academia and engineering circles.A kind of suggestion is thought, is exactly composite foundation as long as pile body is not connected with basis, and being just connected is not composite foundation, is that flexible pile or rigid pile are unimportant as for stake; The view was also expressed, the rigidity size of pile body, that whether pile body is connected with basis is all nothing serious, and can key be under duty, ensure stake and the inter-pile soil load whether shared is transmitted by basis.From developed recently trend, the concept of composite foundation is constantly being opened up extensively, and the Generalized composite foundation concept that stresses load transfer mechanism is taken seriously and develops because having disclosed the essence of composite foundation.
But, due to construction technology, the soil taking hole forming stakes such as similar CFG, construction be can not ignore the impact of surrounding enviroment.Ubiquity periphery place land subsidence, road surface or building masonry wall problems of crack in this kind of stake type work progress.Simultaneously, should be taking soft ground treatment as object, be difficult to ensure card because soil property weakness makes pile quality on the contrary, especially, to existing in the ground of the poor silty clay layer of liquefaction layer of sand or engineering properties, silt soil strata, often occur the construction quality problem such as broken pile, necking down.
Utility model content
The purpose of this utility model is the problem and shortage for above-mentioned existence, and a kind of construction that can effectively improve preformed pile is provided, and greatly improves the preformed pile composite foundation of the supporting capacity of ground simultaneously.
For achieving the above object, the technical scheme of taking is:
A kind of preformed pile composite foundation, comprise and be the preformed pile unit of the uniform setting of matrix, the mattress layer that is arranged on even tiling on preformed pile unit and sclerosis ground basal plane, described preformed pile unit comprises multiple be that matrix arranges are vertically arranged on reinforcement in soil layer and are arranged on the preformed pile cushion cap at each reinforcement top, and described reinforcement comprises reinforcement body and is arranged on the load distribution bar of reinforcement body surrounding.
Described load distribution bar is the helical blade that is spiral and is arranged on reinforcement body surrounding.
Described sclerosis ground face comprises and is arranged on the layer of concrete of mattress layer upside and is arranged on reinforced concrete plinth corresponding with preformed pile unit on layer of concrete.
Described reinforcement body is reinforced concrete pile.
Described mattress layer is rubble, and mattress layer thickness is 200mm ~ 450mm.
Described coagulate layer thickness is 75mm ~ 120mm.
Adopt technique scheme, obtained beneficial effect is:
The utility model is by improvements over the prior art and design, make the preformed pile of composite foundation in work progress, can not destroy original geology soil layer construction, can effectively improve greatly the bearing capacity of whole ground, the utility model reasonable in design, integrated carrying ability is strong, and soil layer construction is tight, and active force is strong each other.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Sequence number in figure: 1 is that reinforcement body, helical blade, 3 are that preformed pile cushion cap, 4 is that soil layer, 5 is that mattress layer, 6 is that layer of concrete, 7 is reinforced concrete plinth.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is elaborated.
Referring to Fig. 1, a kind of preformed pile composite foundation of the utility model, comprise and be the uniform preformed pile unit being arranged in soil layer 4 of matrix, be arranged on mattress layer 5 and the sclerosis ground basal plane of evenly tiling on preformed pile unit, described preformed pile unit comprises multiple be that matrix arranges are vertically arranged on reinforcement in soil layer and are arranged on the preformed pile cushion cap 3 at each reinforcement top, described reinforcement comprises reinforcement body 1 and is arranged on the load distribution bar of reinforcement body 1 surrounding, described load distribution bar is the helical blade 2 that is spiral and is arranged on reinforcement body 1 surrounding, described sclerosis ground face comprises and is arranged on the layer of concrete 6 of mattress layer 5 upsides and is arranged on reinforced concrete plinth corresponding with preformed pile unit on layer of concrete 67, described reinforcement body 1 is reinforced concrete pile, described mattress layer 5 is rubble, mattress layer thickness is 200mm ~ 450mm, described layer of concrete 6 thickness are 75mm ~ 120mm.
Claims (6)
1. a preformed pile composite foundation, it is characterized in that, comprise and be the preformed pile unit of the uniform setting of matrix, the mattress layer that is arranged on even tiling on preformed pile unit and sclerosis ground basal plane, described preformed pile unit comprises multiple be that matrix arranges are vertically arranged on reinforcement in soil layer and are arranged on the preformed pile cushion cap at each reinforcement top, and described reinforcement comprises reinforcement body and is arranged on the load distribution bar of reinforcement body surrounding.
2. preformed pile composite foundation according to claim 1, is characterized in that, described load distribution bar is the helical blade that is spiral and is arranged on reinforcement body surrounding.
