Underground water nest bundle type layered monitoring well system

Abstract

The invention relates to the technical field of underground water monitoring, and particularly relates to an underground water nest bundle type layered monitoring well system. The ends of a plurality of monitoring pipes are located on the same surface, the lengths of the plurality of monitoring pipes are different, and the bottom of each monitoring pipe corresponds to a corresponding water-bearing layer; and a plurality of sunken parts are arranged in the circumferential direction of a positioning pipe, the number of the sunken parts corresponds to the number of the monitoring pipes, and the sunken parts are suitable for embedding of the monitoring pipes. The monitoring pipes and the positioning pipe are tightly connected into a bundle type well pipe, the overall strength of the monitoring pipes and the positioning pipe is guaranteed, then the water stopping effect between the monitoring pipes and the positioning pipe is guaranteed, the overall strength of a monitoring well is improved, and the service life of the monitoring well is prolonged. Due to the fact that the monitoring well only needs to be drilled once, each monitoring pipe and the positioning pipe can be monitored corresponding to the multiple water-bearing layers, the process is simple, the construction efficiency and the well forming quality are improved, the number of drilling construction is reduced, the construction and management cost is saved, and large-scale application and popularization are facilitated.

Description

technical field

[0001] The invention relates to the technical field of groundwater monitoring, in particular to a nest-bundle layered monitoring well system for groundwater. Background technique

[0002] Groundwater monitoring well technology is the foundation of groundwater pollution investigation and protection. At present, one-hole multi-layer monitoring well technology has been widely used in developed countries such as Europe and the United States. The developed single-hole multi-layer monitoring well technologies include nested monitoring wells, continuous multi-layer Channel monitoring well, Waterloo monitoring well and Westbay monitoring well, etc. However, in my country, the monitoring of a single well or a group of wells with different depths is still the main method, and the technology of multi-layer monitoring wells is still in the stage of application and development, and has not yet been widely promoted.

[0003] Nested monitoring well refers to the installati...
