Abstract
The utility model relates to the field of buildings, in particular to a composite pile foundation used for a soft soil building foundation. The composite pile foundation used for the soft soil building foundation comprises an upper-portion foundation body, a bearing layer, reinforced concrete piles and graphite piles. The length of the reinforced concrete piles is equal to the length of the graphite piles, one end of each reinforced concrete pile and one end of each graphite pile are both inserted into the bearing layer, the length by which the end of each reinforced concrete pile is inserted and the length by which the end of each graphite pile is inserted are equal, and the upper-portion foundation body is arranged on the other ends of the reinforced concrete piles and the other ends of the graphite piles. According to the composite pile foundation for the soft soil building foundation, the reinforced concrete piles and the graphite piles are arranged, the length of the reinforced concrete piles is the same as the length of the graphite piles, one end of each reinforced concrete pile and one end of each graphite pile are together inserted into the bearing layer and the upper-portion foundation body is arranged on the other ends of the reinforced concrete piles and the other ends of the graphite piles. Due to the fact that the reinforced concrete piles, the graphite piles and soil below the upper-portion foundation body can together bear the load of a building, the composite pile foundation has good load capacity. Compared with an existing pile foundation, the composite pile foundation used for the soft soil building foundation is reduced in manufacturing cost, and therefore the building cost is lowered.
Description
Technical field
The utility model relates to building field, in particular to a kind of for weak soil building foundation composite pile foundation.
Background technology
At present, the base form that China's building foundation field adopts has three kinds of natural ground, composite foundation and pile foundations.In correlation technique, be directed to Soft Clay, conventionally adopting pile foundation is base form, though adopt the good load of bearing building of this base form energy, pile foundation cost is too high, causes the rising of building costs.Therefore develop and a kind ofly can well bear built-loading, can reduce again the composite pile foundation of building costs, be people's problem demanding prompt solutions.
Utility model content
It is a kind of for weak soil building foundation composite pile foundation, to solve the above problems that the purpose of this utility model is to provide.
In embodiment of the present utility model, provide a kind of for weak soil building foundation composite pile foundation, comprise basis, top, bearing stratum, reinforced concrete pile and graphite stake, reinforced concrete pile and graphite stake equal in length, all insert in bearing stratum one end of one end of reinforced concrete pile and graphite stake, and insertion is equal in length; State on the other end of reinforced concrete pile and the other end of graphite stake and be provided with basis, top.
The utility model above-described embodiment a kind of for weak soil building foundation composite pile foundation, by by the reinforced concrete pile of equal length and graphite stake, and inserts bearing stratum jointly by its one end, its other end be provided with basis, top above.Due to the soil under reinforced concrete pile and graphite stake and basis, top can shared the load of building, therefore composite pile foundation has good weight bearing power.Through a large amount of architectural experiments, prove, be directed to the building foundation of soft clay area, adopt the common composite pile foundation forming of reinforced concrete pile and graphite stake to compare with existing pile foundation, can reduce by 20%～30% pile foundation cost, thereby reduce building costs; And can effectively prevent the sedimentation of building, can be by settlement Control between 1 centimetre～4 centimetres.
Accompanying drawing explanation
Fig. 1 shows a kind of structural representation for weak soil building foundation composite pile foundation that the utility model provides.
The specific embodiment
Below by specific embodiment, also by reference to the accompanying drawings the utility model is described in further detail.
As shown in Figure 1, what the present embodiment provided is a kind of for weak soil building foundation composite pile foundation, comprises basis, top, bearing stratum 6, reinforced concrete pile 4 and graphite stake 5.Reinforced concrete pile 4 is equal in length with graphite stake 5.All insert in bearing stratum 6 one end of one end of reinforced concrete pile 4 and graphite stake 5, and insertion is equal in length.Above the other end of the other end of reinforced concrete pile 4 and graphite stake 5, be provided with basis, top.What the present embodiment provided is a kind of for weak soil building foundation composite pile foundation, by by the reinforced concrete pile of equal length 4 and graphite stake 5, and its one end is inserted to bearing stratum 6 jointly, its other end be provided with basis, top above.Due to the soil under reinforced concrete pile 4 and graphite stake 5 and basis, top can shared building load, therefore composite pile foundation has good weight bearing power.Through a large amount of architectural experiments, prove, be directed to the building foundation of soft clay area, adopt reinforced concrete pile 4 to compare with existing pile foundation with the common composite pile foundation forming of graphite stake 5, can reduce by 20%～30% pile foundation cost, thereby reduce building costs; And can effectively prevent the sedimentation of building, can be by settlement Control between 1 centimetre～4 centimetres.In addition, in the present embodiment, reinforced concrete pile 4 arranges with graphite stake 5 intervals, between two adjacent reinforced concrete piles 4, is provided with a graphite stake 5, and design like this can further can effectively increase the weight bearing power of the composite pile foundation that the present embodiment provides.
As shown in Figure 1, the present embodiment provides a kind ofly can also comprise mattress layer 3 for weak soil building foundation composite pile foundation, mattress layer 3 be arranged on basis, top below, be arranged on reinforced concrete pile 4 and graphite stake 5 above, mattress layer is arranged between top basis and reinforced concrete pile 4 and graphite stake 5.The material of mattress layer 3 can be selected according to the actual needs of building, and its thickness also can need according to actual building to select.In the present embodiment, mattress layer 3 is preferably comprised of rubble and sand, and the thickness of mattress layer 3 is 10 centimetres～25 centimetres.By be provided with mattress layer 3 between reinforced concrete pile 4, graphite stake 5 and basis, top, between the composite pile foundation that can make building and the present embodiment provide, there is good buffering, make this composite pile foundation there is stronger shock resistance.Through seismic resistance calculation, the composite pile foundation seismic resistance calculation that the present embodiment provides reaches 8 degree requirementss for fortification against earthquake.Furthermore, what the present embodiment provided is a kind of for weak soil building foundation composite pile foundation, and basis, top comprises C10 element concrete bed course 2 and raft plate 1, and C10 element concrete bed course 2 is arranged on mattress layer 3, and raft plate 1 is arranged on C10 element concrete bed course 2.Further, in the present embodiment, bearing stratum 6 is boulder bed.Provide in the present embodiment a kind of for weak soil building foundation composite pile foundation is provided, at mattress layer 3, away from a side of C10 element concrete bed course 2, be provided with a slabstone 7, and a stake slabstone 7 is arranged between reinforced concrete pile 4 and graphite stake 5.By being provided with a slabstone 7, can make reinforced concrete pile 4, graphite stake 5 and the basis, top link together closely, further improved the load-carrying ability of the composite pile foundation that the present embodiment provides.
As shown in Figure 1, what the present embodiment provided is a kind of for weak soil building foundation composite pile foundation, first with pile press, graphite stake 5 and reinforced concrete pile 4 is passed to soil layer 8, is pressed into bearing stratum 6.Between graphite stake 5 and reinforced concrete pile 4, a slabstone 7 is set, then graphite stake 5 with reinforced concrete pile 4 above, spread mattress layer 3, finally on mattress layer, spread successively the plain concrete bed course 2 of C10 and raft plate 1.
