Wellhead protection device for automatic underground water monitoring well and installation and use methods

Abstract

The invention discloses a wellhead protection device for an automatic underground water monitoring well. The wellhead protection device comprises a barrel body, a cover body and a semi-buried concrete base; the barrel body comprises an outer barrel body and an inner barrel body; the outer barrel body is fixedly connected to the concrete base; the inner barrel body is fixed in the outer barrel body and is provided with a measuring scale; the bottom end of the measuring scale is connected with a floating ball; a hinged rotating shaft hinged to the top end of the outer barrel is arranged at one end of the cover body; and a fixed supporting system is arranged in the concrete base. The wellhead protection device has the advantages that installation and data transmission of an automatic underground water monitoring device are supported; the underground water level can be automatically measured at any time without being influenced by seasonal change of the water level, data comparison and rechecking are facilitated, and the accuracy of monitoring data is ensured; the fixed supporting system in the base is convenient to construct, firm and reliable, and differential settlement of a foundation can be effectively prevented; and the wellhead protection device is suitable for underground water monitoring work in an artificial fill stratum or a coastal soft soil foundation area.

Description

technical field [0001] The application belongs to the technical field of groundwater monitoring well protection, and in particular relates to a wellhead protection device for automatic groundwater monitoring wells. Background technique [0002] Groundwater monitoring is an important basic work for geological environment change monitoring, analysis and management, and groundwater exploitation control. Most groundwater monitoring work is purely manual. Manual measurement of water volume, water temperature, water level and other data, as well as manual sampling and laboratory analysis, not only have low work efficiency and poor accuracy, but also low monitoring frequency, which cannot meet the real-time data collection and automation requirements for management. . With the help of advanced sensor technology, communication technology and data analysis and processing technology, the application of the groundwater real-time dynamic monitoring system that can realize the automatic...

Problems solved by technology

[0003] Compared with groundwater monitoring wells that use manual observation techniques, the protection devices of automated monitoring wells need to be designed and installed simultaneously with the data acquisition and transmission devices, and have stricter requirements: First, the monitoring equipment is expensive and placed in outdoor monitoring wells , requires strict protection and solid and reliable design to prevent man-made sabotage or theft accidents; secondly, the water pressure sensing and data acquisition and transmission systems of monitoring equipment have high environmental requirements and need to be placed in a stable environment. When built in artificial fill, coastal soft soil layer or other soft ground areas, the foundation base of the monitoring well needs to prevent uneven settlement to ensure the accuracy of monitoring work and data accuracy; three, long-term continuous operation of monitoring instruments Sensitivity may decrease, and the design of the protection device should provide convenient conditions for on-site review of the accuracy of monitoring data; four, it must meet the requirements of monitoring instruments, cable installation, and remote transmission and communication of monitoring data, and the transmission signal cannot be shielded
