Underground water monitoring well used for refuse landfill and construction method of underground water monitoring well

Abstract

The invention relates to an underground water monitoring well used for a refuse landfill and a construction method of the underground water monitoring well. The underground water monitoring well usedfor the refuse landfill comprises a well pipe, the well pipe is vertically arranged and sequentially comprises a solid wall pipe and a perforated pipe from top to bottom, and the solid wall pipe is fixedly connected with the perforated pipe. A top end cap and a bottom end cap are arranged at the upper and lower ends of the well pipe correspondingly, the top end cap is movably connected with the top of the solid wall pipe, and the bottom end cap is fixedly connected with the perforated pipe. The well pipe is buried underground except for the rest of the top end of the well pipe exposed at the ground, and the underground part of the well pipe is covered with a bentonite clay section, a security clay section, a clay closed section and a graded crushed stone section correspondingly from top tobottom. A concrete wellhead sleeves thebentonite clay section, a protective shell is fixedly arranged at the top of the concrete wellhead, the top end of the well pipe is located in the protective shell, and a cover plate is hinged to the top of the protective shell. The underground water monitoring well used for the refuse landfill and the construction method thereof can provide groundwater sampling monitoring to the periphery of the refuse landfill, surface water entering into the well through shallow soil aeration zone, causing the groundwater quality to change, and seriously affecting themonitoring result of the groundwater quality are avoided.

Description

technical field [0001] The invention relates to the field of landfills, in particular to a groundwater monitoring well for landfills and a construction method thereof. Background technique [0002] At present, in the groundwater monitoring wells around the landfill, surface water enters the groundwater monitoring wells through the soil aerated zone through infiltration, which will lead to the fact that the samples taken in the groundwater monitoring wells are not enough to represent the actual groundwater quality. It greatly affects the judgment of technicians on whether the groundwater is polluted or not and the extent of the pollution. Contents of the invention [0003] The invention aims to solve the deficiencies of the prior art, and provides a groundwater monitoring well for landfills and a construction method thereof. [0004] In order to achieve the above object, the present invention adopts the following technical solutions: [0005] A groundwater monitoring well...
