Abstract
The invention particularly relates to an underwater concrete-spraying wall-solidifying drill bit. The drill bit solves the problems that hole walls of an existing underwater foundation easily collapse, phenomena of mud mixing and pile breaking are caused, and accordingly pile-forming quality and safety performance of cast-in-place piles are influenced. The drill bit comprises a hollow drill rod and a drill bit body communicated with the hollow drill rod and located at the lower end of the hollow drill rod, wherein the drill bit body comprises two hollow rods which are vertically crossed and communicated with each other, the lower end face of each hollow rod is fixedly provided with a triangular rotating blade, the two ends of the upper end face of each hollow rod are respectively provided with a spray head communicated with the hollow rod, and spraying baffles are fixed on the upper end faces, on the inner sides of the spray heads, of the hollow rods. The drill bit is reasonable and reliable in structural design, pile hole liquefied soil walls can be solidified, the hole collapse phenomenon is reduced to the maximum degree, furthermore, the phenomena of mud mixing and pile breaking are eliminated, construction quality and security of cast-in-situ bored piles are guaranteed, and the drill bit has the advantages of being simple in structure, convenient to machine and capable of achieving concrete-spraying and wall-solidifying forming in a one-shot mode.
Description
Technical field
The present invention relates to building operations breast wall apparatus, be specially the solid wall drill bit of the foundation drilling filling pile constructions such as a kind of groundwater table is high, soil property Degree of Liquefaction is high silty clay, sand, silt whitewashing under water.
Background technology
Bored pile is in the time running into the wetland such as abandoned channel, beach ground now; disturbance hole wall surrounding soil in boring procedure; because its mud balance does not have reliable retaining wall effect; often can there is the phenomenon of landslide in hole; when fluid concrete; usually can cause because of the landslide of hole wall soil the problem of folder mud and pile breaking phenomenon generation, affect the pile quality of castinplace pile, and the security performance of filling pile construction can not get effectively ensureing.
Summary of the invention
The present invention for solve existing underwater hole wall easily landslide cause the problem of make a difference bored pile piling quality and the security performance of pressing from both sides mud and pile breaking phenomenon, the one solid wall drill bit of whitewashing is under water provided.
The present invention adopts following technical scheme to realize: the solid wall drill bit of whitewashing under water, comprise hollow drill pipe and communicate with it and be positioned at the drill body of its lower end, drill body comprises two square crossings and the hollow stem communicating, the lower surface of hollow stem is all fixed with triangular shape rotating vane, the both ends of hollow stem upper surface are provided with the shower nozzle being communicated with it, and the hollow stem upper surface of shower nozzle inner side is fixed with gear spray plate.
When operation, the rotation of driven by motor hollow drill pipe, and then drive drill body extremely stake end design elevation of rotary cutting soil in stake hole; The solid wall operation of whitewashing subsequently, when drill body rotation is risen, slurries are through hollow drill pipe, hollow stem, nozzle high-voltage ejection, gear spray plate ensures that cement paste does not spray into the soil body at pile body position substantially, only limit sprays into the soil body within the scope of solid wall, form the cylindric cement-soil mixture that has in addition some strength and thickness along pile body, make a hole liquefying soil wall be cured to reduce the phenomenons such as hole of collapsing, overcome the problem that the easy landslide of existing underwater hole wall causes make a difference bored pile piling quality and the security performance of pressing from both sides mud and pile breaking phenomenon.
Reasonable in design of the present invention is reliable, a hole liquefying soil wall is cured, reduce to greatest extent the generation of the hole phenomenon of collapsing, and then the generation of having stopped folder mud and pile breaking phenomenon, guarantee construction quality and the safety of bored pile, there is simple in structure, the easy to process and solid one-time formed advantage of wall of whitewashing.
