Technical Field
The invention relates to the technical field of grouting, in particular to an environment-friendly grouting drilling tool and retainer combined structure.
Background
The retainer is a tool used in connection with drilling tools for drilling holes, boring holes and the like, and plays a role in keeping more than two drilling tools relatively stable. When the drilling machine works, the retainer descends along with the drilling of the drilling tool, ensures that equipment is smoothly stirred into piles to achieve the expected effect during working, is an indispensable important component for keeping the stability of the machine, can be matched with multi-shaft drilling machine equipment such as two, three, four shafts and the like for piling machinery, and is widely applied to large-scale foundation improvement engineering projects such as land, ocean and the like.
The holder on the slip casting rig that uses in the existing market comprises simple steel sheet, and the rig passes through the drilling rod and carries thick liquid to the drill bit in the use, therefore the drilling rod must all contain thick liquid pipe and the leakproofness requirement of butt joint is high, and the structure is complicated, the operation is inconvenient, makes impurity dust get into the slip casting mouth easily when lengthening and dismantling the drilling rod, influences final equipment performance and piling effect, secondly can make the residual thick liquid flow out and pollute the quality of water, can not satisfy the requirement of environmental protection. In addition, as the construction depth increases, the length of the drill rod needs to be increased, and the stability of the multi-axis drill rod in construction cannot be ensured. In order to ensure the stability of drill rods of the multi-shaft drilling machine and ensure the relative positions among the drill rods and the guiding function of the drill rods, only one retainer is adopted, so that the ultra-deep foundation underground construction requirement cannot be met.

Further, 2-5 drill rods and 2-5 drill bits are arranged, and the first retainer and the second retainer are horizontally arranged.
When the drilling tool is in operation, the part, connected with the drilling tool, of the bearing rotates along with the drilling tool, and the other parts of the retainer do not rotate and are lifted and lowered along with the lifting and lowering of the drilling tool.
The concrete working principle of the invention is that the drill rod and the drill bit are fixedly connected through the retainer, the retainer and the drill bit are internally provided with communicated grouting channels, the retainer is provided with a retainer grouting opening, and the drill bit and the retainer are arranged in a sliding connection manner. The drill bit rotates along with the drill rod, slurry is input from the grouting opening of the retainer, sequentially passes through the straight grouting channel and the annular grouting channel arranged around the drill bit, enters the drill bit grouting channel of the drill bit through the drill bit grouting inlet, and finally is sprayed out from the grouting opening to realize grouting. When the drill bit is required to be disassembled and lengthened, the drill bit is separated from the drill rod, and the drill bit is connected with other drill rods, so that only the grouting hose is required to be lengthened. Through this kind of mode transport thick liquid, but not carry thick liquid through traditional drilling rod, can prevent to lengthening and dismantle the drill bit in-process mud leakage and arouse water pollution, work easy operation increases the drill bit practicality, and the energy saving improves the operating efficiency greatly, and the operation security obtains guaranteeing.
Compared with the prior art, 1) the retainer is respectively arranged on the drill rod and the drill bit, so that the problems that the stability of the drill rod cannot be ensured along with the increase of the construction depth and the requirement of ultra-deep foundation underground construction is met are avoided; 2) The problem that the drilling machine can only convey slurry through the drill rod, has high design requirements on the drill rod, is easy to invade dust impurities to affect the equipment performance and the piling effect when the drill bit is disassembled, and has high requirements on the tightness of the drill bit joint because the drill bit can only convey the slurry through the connecting drill rod due to the water pollution problem caused by lengthening and disassembling the drill rod is solved. This structure can ensure the stability of drill bit in the course of the work, can carry thick liquid with the drill bit cooperation again, avoids carrying thick liquid from the drilling rod, and mud leakage causes water pollution when preventing extension and dismantling the drill bit, can prolong the life of drill bit, and the operation security also obtains guaranteeing simultaneously.
