Embodiment Construction

[0018] The present invention is described in further detail below in conjunction with accompanying drawing, see accompanying drawing.

[0019] A layered sampling and repairing device for ground water, the device is composed of a well body, a sampling and repairing unit and a rotary lifting device. The well body is composed of a well pipe 1 , a filter cloth 2 , a filler 3 , a connecting seat 4 , a sealing well cover 5 and a base 6 . The well pipe 1 is a cylindrical pipe, and on the wall of the well pipe 1, there are four rows of slotted areas symmetrically distributed along the axial direction of the well pipe 1. The direction of the slotting is horizontal, the width of the slotting area is 40° arc length, and the distance between the edges of every two lines of slotting area is 50° arc length. A filter cloth 2 is wrapped on the outer wall of the well pipe 1 . The filter cloth 2 is wrapped with filler 3 . The filler 3 can be the backfill of soil excavated for well constructi...

Abstract

The invention relates to a stratified sampling and stratified repair device for groundwater, and belongs to the technical field of environmental science and engineering. The stratified sampling and stratified repair device for groundwater comprises a well body, a sampling and repair unit and a rotary lifting device. A sampling and repair silo arranged in a well pipe can move up and down along the axial direction of the well pipe to any location in the well pipe, and stratified sampling and stratified repair of the groundwater at any depth to be achieved by controlling of the sampling and repair silo to a location to be sampled or repaired. The stratified sampling and stratified repair device integrates the sampling and in situ repair of the groundwater, and by connecting of ground water pumping equipment, air pumping equipment, gas injection equipment or drug injection equipment, groundwater sampling and monitoring, groundwater multi phase extraction repair, extraction processing repair, aeration repair, drug injection repair and other functions can be realized. The stratified sampling and stratified repair device for groundwater has the advantages of reasonable structure, simple operation and convenient operation, and has the multifunction of groundwater sampling and various technical repair.

Description

technical field [0001] The invention relates to a layered sampling and repairing device for groundwater, which is mainly used for sampling and in-situ repairing of groundwater samples at a specified depth, and belongs to the field of environmental science and engineering technology. Background technique [0002] According to the 2013 Bulletin on the State of the Environment in China, among the 4,778 groundwater environmental quality monitoring points across the country, 43.91% and 15.7% of the monitoring points had poor water quality and extremely poor water quality, respectively. The deterioration of groundwater quality has made the relatively scarce groundwater resources less and less available. With the acceleration of urbanization and industrialization in our country, the problem of groundwater pollution in some areas has become increasingly prominent, which has seriously affected the production and life of the people. The protection of groundwater environment has been h...
