Weifang Diyuan Air Conditioning

The construction technology of ground-source air-conditioning water wells is divided into: drilling, drilling, porous detection wells, punching, replacing slurry well pipes, installing backfill filter materials, clay sealing well cleaning, and pumping and reinjection test tube well acceptance. The following is a detailed introduction for you: Drilling wellbore
The diameter of the borehole should be determined according to the outer diameter of the well pipe and the type of the main aquifer: in the hard rock and coarse sand layers, the hole diameter should be larger than the outer diameter of the well pipe. Larger in medium, fine, and silt sand layers, it should be greater than.
, Physical detection well
After the well hole is drilled, it is necessary to carry out physical detection well immediately to find out the stratigraphic structure, the depth and thickness of the water-bearing well and the aquifer, the quality of the groundwater, etc., so as to install the well pipe. , gravel filling and clay sealing provide reliable information.
, Punching and slurry replacement
In order to discharge the mud and sediment in the well hole out of the well hole before installing the well pipe, punching and slurry replacement should be performed. That is, use a drilling rig to put the drill pipe without a drill bit into the bottom of the well, use a mud pump to suck clean water into the well, and replace the mud until the well hole is filled with clean water.
, Well pipe installation
After the slurry replacement is completed, the well pipe installation (referred to as pipe running) should be carried out immediately. The order of running pipes is generally sedimentation pipe, filter pipe, and well wall pipe. Note during installation: The length and installation position of the filter should be determined based on the well drilling data.
