Abstract
The rotary digging drilling hole bored concrete pile that steel reinforcement cage band covers in a kind of Soft Soil Layer, pile foundation engineering field, including steel reinforcement cage are the utility model is related to, wraps up geotextiles on the outside of steel reinforcement cage, geotextiles are fixed on steel reinforcement cage by horizontal location muscle and circular orientation muscle.The utility model solve conventional rotary digging drilling hole bored concrete pile technique in cumulosol, strawberry is native, when being constructed in soft creeping modeling shape silt soil strata, concrete spreads to the periphery soil body and causes pile quality to be difficult to the technical barrier excessive with fullness coefficient that be guaranteed.And can saves a large amount of concrete while pile quality is guaranteed.
Description
Technical field
It the utility model is related to rotary digging drilling hole bored concrete pile, the rotary digging drilling hole that steel reinforcement cage band covers in especially a kind of Soft Soil Layer fills
Stake is noted, belongs to pile foundation engineering field.
Background technology
Such as in the gyittja soil layer of Kunming, Yunnan Dian Chi section, thicker strawberry soil, peat are distributed with duricrust clay layer
Matter is native and soft modeling~current-formed silt matter soil, these soil layers have the characteristics that moisture content is high, void ratio is big, natural density is low.
Problems be present when applying construction technology using conventional rotary digging drilling hole bored concrete pile in the section：(1) stream modeling shape cumulosol and high hole
Gap using common rotary digging drilling hole bored concrete pile technique than in strawberry soil (unit weight is up to more than 2.5 slightly larger than water, void ratio), being applied
Man-hour, institute's placing concrete easily to the periphery soil body spread and cause fullness coefficient excessive, corresponding fullness coefficient up to 3.0 with
On.(2) concrete to the periphery soil body spread when, stake top concrete liquid level constantly declines, can be new if now teeming concrete
Old concrete intersection is mingled with mud and causes broken pile.(3) after concrete spreads to the periphery soil body, periphery Spiral digging machine pore-forming is caused
Difficulty even can not pore-forming.
The content of the invention
The utility model provides the rotary digging drilling hole bored concrete pile that steel reinforcement cage band covers in a kind of Soft Soil Layer, and concrete scheme is as follows：
The rotary digging drilling hole bored concrete pile that steel reinforcement cage band covers in a kind of Soft Soil Layer, including steel reinforcement cage, it is characterised in that：Also include soil
Work cloth, geotextiles are wrapped on the outside of steel reinforcement cage, and geotextiles are fixed on steel reinforcement cage by horizontal location muscle and circular orientation muscle.
Further, horizontal location muscle is symmetrically welded in the cage bar of steel reinforcement cage.
Further, horizontal location muscle width is equal to filling pile cage of reinforcement thickness of concrete cover.
Further, circular orientation muscle is welded on the outside of horizontal location muscle.
Further, geotextiles are fixed on circular orientation muscle by tied silk or cord.
Compared with prior art, the beneficial effects of the utility model are：
Geotextiles are wrapped on the outside of steel reinforcement cage by circular orientation muscle and horizontal location muscle, institute's placing concrete is installed in
In geotextiles.Solve conventional rotary digging drilling hole bored concrete pile technique in cumulosol, strawberry is native, soft modeling~current-formed silt matter soil layer
During middle construction, concrete spreads to the periphery soil body and causes pile quality to be difficult to the technology hardly possible for being guaranteed excessive with fullness coefficient
Topic.And can saves a large amount of concrete while pile quality is guaranteed.

Horizontal location muscle 03 and spacing of the circular orientation muscle 02 along the length direction of steel reinforcement cage 01 be 1000mm~2000mm it
Between.As shown in figure 3, the construction technology process 10 of the present embodiment starts from step S11, wherein prepare before carrying out every construction, such as
Construction machinery, material, personnel, confide a technological secret, levelling of the land, machine-walking road bedding compacting etc. preparation.
Step S12 be mechanical package, debugging, test running, mud pit excavate, surveying setting-out go out a site.
Enter step S13 after the completion of step S12, prepare mud, mud match ratio determines according to field test.
After the completion of step S13, technique enters step S14, and measurement, unwrapping wire orient stake position, stake position made with albarium
Mark.
Step S14 enters step S15 immediately when completing, steel reinforcement cage processing, during steel reinforcement cage processing in cage bar weld horizontal
Positioning bar 03, horizontal location muscle 03 should be carried out symmetrically when welding, and horizontal location muscle 03 is remote in horizontal location muscle after the completion of welding
Annular positioning bar 02 is welded in one end of steel reinforcement cage, and horizontal location muscle 03 and circular orientation muscle 02 are along between the length direction of steel reinforcement cage 01
Away between 1500mm~2000mm.Circular orientation muscle 02 is consolidated after the completion of constructing on circular orientation muscle 02 using tied silk or cord
Determine the overcoat of geotextiles 04.
When step S15 is carried out, step S16 is carried out simultaneously, and using rotary drilling rig pore-forming, pore-forming is qualified up to verifying.Step
After the completion of S16, into step S17, telephone-moving to next position is constructed after pore-forming and acceptance(check).When step S17 is completed, enter
Enter step S18, hung in the band processed set steel reinforcement cage in hole and up to acceptance(check) using crane or other Special cranes.Step
