Underground water monitoring well and mounting method thereof

Abstract

The invention relates to an underground water monitoring well and a mounting method thereof. A well body is arranged to be in the form of an inner pipe and an outer pipe which are coaxial, the top ofthe outer pipe is protected and sealed through a pipe cap, air tightness is guaranteed, a water pump acts on the top of the inner pipe, and underground water is extracted for well washing and samplingthrough a water area of the underground water, the outer pipe and the inner pipe which are sequentially communicated in space; and fastening units are arranged between the inner pipe and the outer pipe and between the outer pipe and a water area of underground water, and stability and smooth operation of the monitoring well are guaranteed. In the installation process, configuration and position adjustment between a water area of underground water and the outer pipe and between the outer pipe and the inner pipe are conducted in a layer-by-layer fixing mode, and the purpose of proper installation is achieved. The water pump can be directly connected with the inner pipe, operation is easy, convenient and fast, flexibility is high, cross contamination caused in the water taking process can beeffectively avoided, suspended particles in pumped underground water are reduced, original functions of a traditional underground water monitoring well are not affected, extra protection is not needed, and damage is not likely to happen.

Description

technical field [0001] The invention relates to the technical field of testing or analyzing materials by means of measuring their chemical or physical properties, in particular to a groundwater monitoring well and an installation method thereof. Background technique [0002] With the continuous development of social economy and population growth, the demand for water resources in society is also increasing rapidly. Due to the over-exploitation of groundwater resources, the groundwater level has dropped, leading to the depletion of water sources, and the increasingly serious environmental pollution on the surface has further aggravated the pollution of groundwater resources. According to the "2017 China Ecological Environment Status Bulletin", in 2017, 5100 Among the water quality monitoring points, the proportion of poor and extremely poor groundwater accounts for 2 / 3 of the total. [0003] In response to the increasingly serious groundwater pollution, my country has promul...

AI Technical Summary

Problems solved by technology

[0005] The invention solves the problem that in the prior art, the traditional groundwater monitoring wells are relatively simple in structure, and the efficiency of well washing and sampling by means of water intake such as Baylor pipes is extremely low, and it takes more than 12 hours to wash a single well, which often cannot meet the needs of on-site well washing. and sampling requirements, there are also risks such as blockage of the well pipe caused by the damage of the Baylor pipe. An optimized groundwater monitoring well and its installation method are provided, which are mainly suitable for the collection of groundwater samples in polluted sites.
