Collecting device of different levels of underground water

Abstract

The invention discloses a collecting device of different levels of underground water. The collecting device comprises a plurality of collecting pipes capable of being spliced mutually, wherein a plurality of slits which are communicated with inner parts and outer parts of the collecting pipes are engraved on the outer walls of the collecting pipes; the collecting pipe positioned on the lowermost end is provided with a hollow conical drill head; the inner parts of the collecting pipes are provided with a plurality of moisture collecting funnels by an embedded connection mode; small holes are formed in the side walls of the moisture collecting funnels; the lower end of each moisture collecting funnel is connected with a water guide pipe and a gas pipe. The collecting device of different levels of underground water has the following characteristics that underground water samples at different levels are collected by the moisture collecting funnels installed on different collecting pipes, are guided out of the ground surface by corresponding water guide pipes, and are collected; the collecting device is convenient to carry, can be spliced to the required length, is simple and convenient to install, is low in construction quantity, can be used continuously by installation once, is small in occupied space, and damages few sampling sites; the gas pipes and the water guide pipes can be replaced to be used mutually, and can be filled with clean water to be cleaned; the problem of sampling and collecting difficulty of shallow layers of underground water at different levels is solved.

Description

technical field [0001] The invention relates to a collection device for groundwater at different levels. Background technique [0002] With the rapid development of industry and unreasonable agricultural investment, the quality of groundwater is seriously threatened. Chemical fertilizers, pesticide inputs, industrial wastewater, organic compounds and other harmful substances in agricultural production migrate to the deep soil layer with surface water after rainfall, causing groundwater to be polluted and causing environmental hazards. [0003] At present, the collection and collection of groundwater are mostly collected by excavation profiles, seepage trays, etc., the equipment installation and collection efficiency are not ideal, the soil is disturbed during collection, and the long time since the start of collection cannot really reflect the time situation of groundwater. The water in the upper layer of the profile is likely to interfere with the lower layer, resulting...
