Abstract
The invention relates to a stirring drill bit with multiple layers of blades and a plurality of spouting holes. The stirring drill bit comprises a drill rod and a drill tip arranged at the end part of the drill rod, wherein the blades are fixedly connected onto the drill rod and the spouting holes are formed in part of the blades. The stirring drill bit has the benefits as follows: the structure is simple; the soil body stirring and cutting frequency can be increased by configuring the blades, so that soil bodies do not need to be repeatedly stirred; and meanwhile, a curing agent such as cement paste or the like is sprayed by the spouting holes, so that the soil bodies are fully reacted with the curing agent for solidification, thereby improving the pile forming quality and efficiency.
Description
Technical field
The present invention relates to building lot and handle the facility of construction, drill bit is stirred in the multilayer blade multiple spot whitewashing that is particularly useful for the reinforcement of soft soil agitation pile.
Background technology
Extensively adopted the processing method of cement mixing method in building Soft Ground field, its way is by curing compound such as mechanical blade rotation stirring original position soil body while gunites, make curing compound and soil carry out a series of chemical reaction, generation has certain structural and intensity to be higher than the solid that adds of weak soil far away, has improved the supporting capacity of weak soil.
Yet in the practice of construction process, because the blade of cutting soil is few, need repeatedly repeats stirring and could guarantee that the soil body is cut fully, pulverizes; Simultaneously because shotcrete pipe is fixed a hole, curing compound can not uniform distribution in the pile body that forms, and in drilling rod high speed rotary course, cement paste concentrates on the pile body external surface, thereby causes various construction quality problems.
Summary of the invention
The technical problem to be solved in the present invention, provide a kind of simple in structure, and can significantly improve efficiency of construction, improve cement paste and curing compound etc. and pulverize evenly with the soil body that stirring is isolated, and fully stir, guarantee that drill bit is stirred in the multilayer blade multiple spot whitewashing of pile quality.
The technical scheme that adopts is:
Drill bit is stirred in multilayer blade multiple spot whitewashing, comprises drilling rod, is located at the apex point of drill rod end.Be fixedly connected with the multilayer blade on the described drilling rod, wherein be laid with the multiple spot gunniting hole on the partial blade.
Above-mentioned multilayer blade is three to four layers, and every layer of three blade are also evenly fixedlyed connected with drilling rod by 120 degree.
Every layer of above-mentioned three blade are not or not a plane, and it is between the upper and lower every 30-50mm.
Above-mentioned blade becomes 90 degree with drilling rod.
Above-mentioned multiple spot gunniting hole is laid on the intermediate layer blade of multilayer blade, and the intermediate layer blade of laying the multiple spot gunniting hole compares other blades and shortens 50mm.
Above-mentioned multiple spot gunniting hole is four to five gunniting holes and uniform on blade, and its diameter is the circular hole of 3-5mm, and the direction of gunniting hole is level.
The invention has the beneficial effects as follows: simple in structure, by being set, the multilayer blade can increase the stirring of the each several part soil body, cutting number of times, need not to repeat to stir, curing compound such as the cement paste of multi-point injection simultaneously make the each several part soil body fully and the curing compound reaction is solidified, and improve pile quality and efficient.
