Abstract

The invention provides a slurry direct cyclic rotation drilling punching and slurry return device of a ground source heat pump. The drilling punching and slurry return device comprises a drilling punching part and a slurry return part. The drilling punching part comprises a drill bit body and a drill bit substrate. The slurry return part comprises an injecting mechanism and a discharging mechanism. The injecting mechanism comprises an injecting pipe and an injecting spray hole. The discharging mechanism comprises a discharging hole and a discharging pipe. The drilling punching and slurry return device is a combination of the drilling punching and slurry return functions, injection of clean water and slurry discharging are ensured while the drilling punching quality is ensured, slurry generated during drilling punching is effectively utilized, the drilling punching cost is effectively reduced, and the drilling punching and slurry return device is suitable for being applied and popularized.

Description

technical field [0001] The invention belongs to the technical field of ground source heat pump engineering, and in particular relates to a ground source heat pump mud positive circulation rotary drilling drilling and return slurry device. Background technique [0002] In the ground source heat pump project, it is necessary to drill holes down the surface to facilitate the normal progress of other process steps. At present, when drilling and drilling, in order to prevent the dust generated by drilling and drilling from pouring out of the surface to pollute the environment, and at the same time to facilitate the discharge of the generated soil, it is generally chosen to fill the drilling hole with water, settle the dust together with the soil, stir and suck it out. However, when the diameter of the drilling hole is large, uniform irrigation cannot be achieved, resulting in incomplete dust settlement or incomplete suction of the soil, which has a certain impact on the construct...
