Pouring and injection integrated indoor testing device and method for monitoring underground water seepage and precipitation

Abstract

The invention provides a pouring and injection integrated indoor testing device and method for monitoring underground water seepage and precipitation. The pouring and injection integrated indoor testing device comprises a visualized round model barrel; a plurality of water penetrating plates are inserted into the visualized round model barrel; a rectangular soil sample box is formed between the water penetrating plates; a soil sample is stored in the rectangular soil sample box; a recharge well and a water precipitation well, which are connected with a water supply device, are inserted into the soil sample, and can be used for pumping and injecting water layer by layer; a pore water osmotic pressure sensor, a soil pressure sensor, a displacement sensor and a water pressure metering instrument, which are connected with an information analysis system, are buried in the soil sample; a water level variable water tank chamber is formed between the water penetrating plates and the round model barrel; and the water level variable water tank chamber is used for simulating a real working condition by controlling the height of a water level through flow control valves mounted on the recharge well and the water precipitation well.

Description

technical field [0001] The invention relates to a new type of indoor test device integrated with perfusion for monitoring groundwater seepage and settlement and an operation method. Background technique [0002] Groundwater is a very precious resource. With the acceleration of China's urbanization process, in terms of groundwater exploitation, my country's groundwater exploitation has increased at an average rate of 2.5 billion cubic meters. The urban scale and the utilization rate of underground space resources have continued to increase, causing a large amount of groundwater loss. The development of artificial groundwater recharge can greatly alleviate this problem, reduce the large-scale and uneven ground subsidence caused by precipitation, and play an important role in protecting groundwater resources. Due to the complexity of the construction site, in many cases it is necessary to conduct indoor tests to simulate recharge and determine key parameters in order to guide ...

AI Technical Summary

Problems solved by technology

However, recharge tests in actual projects often take a long time and are expensive, and only a single recharge test is performed, lacking comprehensive measurement and processing of various variables, and lack of comprehensive consideration of precipitation and recharge
