First, the excavation pit body: according to the actual need to choose different specifications and models of products, the pit body is larger than the well body more than 50 centimeters, the depth is greater than the well height of 8 centimeters, for the installation of surface load-bearing well cover.

Second, the well body opening: well wall opening is based on the outer diameter of the inlet and outlet pipes to determine the size and height of the opening. Use the hand drill to install the corresponding hole opener.
Third, the water pipe through the well wall, our company only provides self-developed rubber sealing ring, rubber ring installation if the pipeline from the well to the well outside the rubber ring convex surface facing outward, when the pipeline from the well to the well outside the rubber ring convex surface facing inward, first fixed rubber ring in the well wall opening, in order to reduce the resistance to penetration, please apply a little detergent or soapy water and other lubricants on the head of the pipeline from the outside to penetrate.
Fourth, the well water meter or valve can be installed before the well body into the pit, or after the pit, after installing the water meter or valve in the well body connection groove into the structural sealant, and then the well body up and down the two together, in the well body around the reserved hole installed on the screw and tighten, you can backfill, well with enough space for workers to operate.
Five, deeper permafrost areas, if the well height is not high enough, can be used to deepen the well barrel specially developed by our company to increase the height, this deep well barrel comes with O-ring seal, waterproof insulation effect is not affected.
Six, backfill: well installation, cover the well mouth sub-cover, to prevent foreign objects into the well, with 2:8 gray soil backfill around the well, layer by layer ramming, each layer 200mm. ramming backfill to the well neck. Pay attention to the protection of the well body and pipeline, do not use sharp hard objects and other irregular garbage. Support the surface well cover, measure the center and the height of the perimeter, the surface is covered with concrete pouring, the outer edge is larger than the well body, so as not to directly bear the weight of the underground well body, and the ground will be smoothed solid, and slightly higher than the perimeter, to prevent rainwater into the well. Before the well body is put into the well pit, the pit base should be treated and compacted with 3:7 gray soil or poured with plain concrete, with a thickness of not less than 100mm, or covered with cement cover.
Seven, recommendations: heavy roadway wellhead pouring reinforcement mesh .
key word:
according,greater,specifications
