Abstract
The invention is a bored pouring pile hole-bottom grouting pile forming method. In the existing building foundation engineering construction, full play can not be effectively given to the pile body intensity and pile end bearing capacity, having defects of high manufacturing cost and so on. And the invention can solve the above problem, firstly boring by spiral borer to the designed level and then grouting the borehole, drawing out drill rod and inserting reinforcement cage, and finally pouring concrete to form pile. And the invention is applied to the building foundation engineering construction.
Description
Technical field:
The present invention relates to a kind of construction that pours into reinforced concrete pile in the building foundation engineering construction field.
Background technology:
In existing building foundation engineering construction, generally adopt bored pile to handle the building that shallow foundation can not meet the demands, common bearing capacity of borehole bored concrete pile is lower, and stake end loosened soil is difficult to handle, can not effectively bring into play the bearing capacity of pile shaft concrete strength and stake end, have drawbacks such as economical cost height.The inventive method can solve above problem effectively.
Summary of the invention:
The purpose of this invention is to provide loosened soil at the bottom of a kind of consolidation pile effectively and improve the drilling poured-pile hole-bottom slurry-injection pile-forming method of the bearing capacity of stake.
Above-mentioned purpose realizes by following technical scheme:
A kind of piling method of bored pile hole-bottom slurry-injection at first with spiral drilling machine boring, is holed and inject cement paste in boring to design elevation, proposes drilling rod after the slip casting and inserts reinforcing cage, last concrete perfusion pile.
The piling method of above-mentioned bored pile hole-bottom slurry-injection, described cement injection are to inject cement paste by auger stem.
This technical scheme has following beneficial effect:
1. utilizing the inventive method institute pile is cast-in-situ concrete poured stake, and piling method is simple.
2. noiselessness pollution, friction public hazards when piling method of the present invention is constructed, job practices is easy.
3. piling method of the present invention has promptly satisfied the feature of traditional castinplace pile, and bull stick is unearthed outward, and slip casting in the bull stick has overcome the unmanageable problem of loosened soil at the bottom of traditional priming concrete pile hole, has improved the bearing capacity of stake end simultaneously again.
4. utilize piling method of the present invention, the cost that has reduced traditional castinplace pile can create very high economic benefit more than 10%, so the prospect of piling method of the present invention is very extensive.
5. utilize piling method of the present invention that the supporting capacity of stake is improved, and handle pile for remaining loosened soil at the bottom of the stake by cement paste, the inventive method can effectively be brought into play the intensity of pile concrete and the supporting capacity of stake end.

Accompanying drawing 2 is the construction schematic diagrames that carry out slip casting according to method of the present invention;
Accompanying drawing 3 is construction schematic diagrames of carrying brill according to method of the present invention;
Accompanying drawing 4 is construction schematic diagrames of laying reinforcing cage according to method of the present invention;
Accompanying drawing 5 is the construction schematic diagrames that carry out fluid concrete according to method of the present invention.
The specific embodiment of the present invention:
Embodiment 1:
A kind of piling method of bored pile hole-bottom slurry-injection at first with spiral drilling machine boring, is holed and inject cement paste in boring to design elevation, proposes drilling rod after the slip casting and inserts reinforcing cage, last concrete perfusion pile.
The concrete steps of the inventive method are:
1, uses auger stem in foundation soil, to hole, form the stake hole;
2, this is bored into the predetermined degree of depth, carries out slip casting according to the situation of stake end soil layer, by the degree of depth and drawing situation control grouting amount (amount of injecting cement paste is determined according to the stratum) and the grouting pressure that enters stake end soil layer;
3, carry brill and remove surflaes, pile hole;
4, lay pile cages to design elevation;
5, build the pile concrete pile that vibrates.
Embodiment 2:
The piling method of embodiment 1 described bored pile hole-bottom slurry-injection, described cement injection are to inject cement paste by auger stem inside in the stake hole.
Claims (2)
1. the piling method of a bored pile hole-bottom slurry-injection is characterized in that: at first with spiral drilling machine boring, hole and inject cement paste in boring to design elevation, propose drilling rod after the slip casting and insert reinforcing cage, last concrete perfusion pile.
2. the piling method of bored pile hole-bottom slurry-injection according to claim 1 is characterized in that: described cement injection is for injecting cement paste by auger stem.
