For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: provide a kind of construction refuse regenerated draining CFG pile foundation, comprise bearing stratum and the soil body, described bearing stratum is positioned at the below of the soil body, circular sand drain is squeezed in the described soil body, in the annulus of described sand drain, penetration concrete forms pile body, and described sand drain is positioned at same straight line with the axle center of described pile body and the degree of depth of the two is identical, and the depth H 3 that described sand drain and pile body enter bearing stratum is not less than 0.5 meter.
Preferably, the material of described pile body adopts the concrete made of construction refuse regenerated aggregate.
Preferably, one deck mattress layer is covered at the top of described sand drain and pile body.
Preferably, the material of described mattress layer adopts construction refuse regenerated aggregate.
Preferably, construction refuse regenerated sand is filled with in described sand drain.
For solving the problems of the technologies described above, another technical scheme that the utility model adopts is: the construction method providing a kind of construction refuse regenerated draining CFG pile foundation, comprises the steps:
One, flatten construction plant, the true fixed pile of unwrapping wire, stake machine moves into place, and casing adjustment is vertical;
Two, sink tube method construction in, pore-forming utilizes discarded sandstone aggregate to stir according to match ratio simultaneously and makes concrete;
Three, after pore-forming, put into bellows, then outside bellows, pour into reclaimed sand, be filled to about hole depth half position time, in bellows, then pour into the concrete stirred, pour into the degree of depth about 1/3rd hole depth;
Four, promote casing to three/mono-hole depth place, then to stake top, then extract casing to lateral irrigation sand outside bellows;
Five, after extracting casing, the concrete stirred is poured into bellows to stake top, form CFG pile body, then telephone-moving is constructed next pile;
Six, after draining CFG pile driving construction completes, leveling stake top mark is high, builds the mattress layer that transmission coefficient is higher, then maintenance;
Seven, after maintenance expires, carry out banketing precompressed, the water in the soil body is introduced sand drain, then overflow earth's surface along mattress layer, thus by the foundation soil shared bearing capacity after CFG pile body and discharging consolidation.
The beneficial effects of the utility model are: 1, sand drain concretion method and CFG stake method are united and applied in basement process, water in Soft Soil Layer is introduced in sand drain by precompressed of banketing by soft foundation, then earth's surface is overflowed by the mattress layer that transmission coefficient is higher, accelerate Soft Soil Layer discharging consolidation, improve bearing capacity, bear vertical load additionally by CFG pile body, the two synergy, improve soft foundation bearing capacity further; 2, construction refuse regenerated aggregate be used as sand drain material and make regeneration CFG stake, the recycling of building waste can be realized, save natural resources, reduce environment pollution, reducing the construction costs.
Accompanying drawing explanation
Fig. 1 is the perspective view of a kind of construction refuse regenerated draining CFG pile foundation one of the utility model preferred embodiment;
In accompanying drawing, the mark of each parts is as follows: 1, the soil body, and 2, pile body, 3, sand drain, 4, mattress layer, 5, bearing stratum.
Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, to make advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus more explicit defining is made to protection domain of the present utility model.
Refer to Fig. 1, the utility model embodiment comprises:
A kind of construction refuse regenerated draining CFG pile foundation, comprise bearing stratum 5 and the soil body 1, described bearing stratum 5 is positioned at the below of the soil body 1, circular sand drain 3 is squeezed in the described soil body 1, in the annulus of described sand drain 3, penetration concrete forms CFG pile body 2, described sand drain 3 is positioned at same straight line with the axle center of described pile body 2 and the degree of depth of the two is identical, and the depth H 3 that described sand drain 3 and pile body 2 enter bearing stratum 5 is 0.5 meter, the concrete that the material of described pile body 2 adopts construction refuse regenerated aggregate to make.
One deck mattress layer 4 is covered with the top of pile body 2 at described sand drain 3, the material of described mattress layer 4 adopts construction refuse regenerated aggregate, water in the soil body 1 is introduced in sand drain 3 by precompressed of banketing by soft foundation, then earth's surface is overflowed by the mattress layer 4 that transmission coefficient is higher, accelerate Soft Soil Layer discharging consolidation, improve bearing capacity.
