Karst underground mud and sand monitoring and receiving device

Abstract

The invention discloses a Karst underground mud and sand monitoring and receiving device, which consists of a flow collecting system (1), a filtering and collecting system (2), a support frame (3) and a flow monitor (4), wherein the flow collecting system (1) is a cylindrical or rectangular flow collecting pipeline; the filtering and collecting system (2) consists of three parts including a nylon net at the upper layer, a spongy layer at the middle layer and a nylon ring at the bottom layer; the flow collecting system (1) is connected with the filtering and collecting system (2); the filtering and collecting system (2) is arranged on the support frame (3); the flow monitor (4) is connected with the bottom of the filtering and collecting system (2) through a pipeline (5). The Karst underground mud and sand monitoring and receiving device has the characteristics that the cost is low; the mud and sand receiving effect is good; the water flow rate metering density is high; the stability is high; the use is convenient. The requirements of Karst regions on the underground soil loss sample collection can be met.

Description

technical field [0001] The invention relates to an underground sediment monitoring and receiving device, in particular to a karst underground sediment monitoring and receiving device for soil erosion caused by underground fissures and karst caves. Background technique [0002] Water and land resources are precious resources on the earth. The destruction and loss of water and soil resources and land productivity under the action of external forces such as water, gravity, and wind, including land surface erosion and loss of water and soil, is called soil erosion. The erosion of soil and water leads to the evolution of rocky desertification. In order to further study the mechanism process of underground soil loss, researchers at home and abroad need to collect soil loss samples. At present, the technical devices for collecting underground soil loss samples are not perfect. Basically, buckets or simple containers are placed under underground fissures to collect lost soil sampl...

AI Technical Summary

Problems solved by technology

At present, the technical devices for collecting underground soil loss samples are not perfect. Basically, buckets or simple containers are placed under underground fissures to collect lost soil samples. In the case of complex underground environments, the receiving effect of these sediment receiving devices is not good. Not very good, for example, in karst caves, the rising water level of the underground river or the erosion of the water flow during the rainy season will wash away the receiving device, the uneven or steep ground below the underground fissure makes it impossible to install, and the receiving device also receives the lost water body, Difficulty in extracting lost soil samples, etc. Lost water and lost soil cannot be separated and received
