Abstract

A multi-tiered-blade multi-point-spouting stirring drill bit comprises a drill stem and a drill tip at the end of the drill stem. A plurality of tiers of blades are fixedly connected to the drill stem, and each of part of the blades is provided with multi-point spouts. The multi-tiered-blade multi-point-spouting stirring drill bit has the advantages that the multi-tiered-blade multi-point-spouting stirring drill bit is simple in structure, stirring and cutting times for soil at all positions can be increased by the aid of the plurality of tiers of blades, no repeated stirring is required, the soil at all positions is fully solidified to firming agents by multi-point spouting of the firming agents such as grout, and piling quality and efficiency are improved.

Description

Drill bit is stirred in the whitewashing of multilayer blade multiple spot
Technical field
The utility model relates to the facility that building lot is handled construction, and 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 through 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,, need repeatedly repeat stirring and could guarantee that the soil body is cut fully, pulverizes because the blade of cutting soil is few; Simultaneously because the fixing hole of shotcrete pipe, 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.
The utility model content
The technical problem that the utility model will solve; 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 also evenly are fixedly 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 at a distance from 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 on blade, is uniformly distributed with that its diameter is the circular hole of 3-5mm, and the direction of gunniting hole is a level.
The beneficial effect of the utility model is: simple in structure; Through 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 and the abundant and curing compound reaction curing of the each several part soil body improve pile quality and efficient.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the vertical view of Fig. 1.
The specific embodiment
Drill bit is stirred in multilayer blade multiple spot whitewashing, comprises drilling rod 1, is located at the apex point 2 of drill rod end.Be fixedly connected with three layers of blade 3 on the described drilling rod 1, every layer of three blade are not or not a plane, between the upper and lower at a distance from 50mm; Three blades are evenly fixed with drilling rod by 120 degree, and the blade after fixing becomes 90 to spend with drilling rod, and the intermediate blade of three layers of blade 3 is promptly than the second layer blade of first and the 3rd layer of blade weak point 50mm; Its each blade is evenly equipped with 4 gunniting holes 4; Gunniting hole 4 diameters are the circular hole of 5mm, and the direction of spray-hole is a level, and drill bit is stirred in said formation multilayer blade multiple spot whitewashing.
