Description
Technical field
The utility model relates to a kind of pile foundation pore-forming secondary pile hole cleaning constructions.
Background technique
Pile foundation pore-forming needs to carry out secondary pile hole cleaning, but existing borehole cleaning configurations effect is undesirable, needs further to add
To improve.
Summary of the invention
The purpose of this utility model is to provide a kind of pile foundation pore-forming secondary pile hole cleaning constructions easy for construction, effect is good.
The technical solution of the utility model is:
A kind of pile foundation pore-forming secondary pile hole cleaning construction, it is characterized in that: including the steel pile casting that pile foundation pore-forming top is arranged in, conduit
Across steel pile casting and the lower part of pile foundation pore-forming is protruded into, conduit upper end is equipped with the slag notch being located above ground handling platform, slag notch
Slag basket is arranged in lower section；The upper end of air hose is connect with air compressor machine, and the lower end of conduit is protruded into the lower end of air hose.
Air hose lower end is away from conduit base opening 200mm；Air hose use Φ 25mm plastic water pipe, bottom duct 1m range internal drilling,
Bore dia is Φ 8mm, and quantity is 20-25, and point 4 arrangements are set.
The utility model is easy for construction, effect is good.
Detailed description of the invention
The utility model is described in further detail with reference to the accompanying drawings and examples.
Fig. 1 is the structural schematic diagram of the utility model one embodiment.
Specific embodiment
A kind of pile foundation pore-forming secondary pile hole cleaning construction, the steel pile casting 2 including 1 top of pile foundation pore-forming is arranged in, conduit 3 pass through steel
Casing and the lower part for protruding into pile foundation pore-forming, conduit upper end are equipped with the slag notch 5 for being located at 4 top of ground handling platform, slag notch lower section
Slag basket 6 is set；The upper end of air hose 7 is connect with air compressor machine, and the lower end of conduit is protruded into the lower end of air hose.
Air hose lower end is away from conduit base opening 200mm；Air hose use Φ 25mm plastic water pipe, bottom duct 1m range internal drilling,
Bore dia is Φ 8mm, and quantity is 20-25, and point 4 arrangements are set.
Gas-liquid mixture is formed along conduit displacement pile bottom through air hose using compressed air.Bottom hole sediment is spraying gas
Percussion under suspend, due to the density contrast of the inside and outside liquid of pipe, the three-phase flow of mud, air, sediment is along conduit in hole
It runs up and is discharged aperture and enters slag basket.After filtering out the sediment in mud, mud after filter is again in access aperture, instead
Multiple circulation is until bottom hole sediment thickness reaches code requirement.
