Experimental device and experimental method of researching and removing blocking suspended solids surrounding seepage well

Abstract

The invention discloses an experimental device of researching and removing blocking suspended solids surrounding a seepage well. The experimental device of researching and removing blocking suspendedsolids surrounding a seepage well includes a sand box and a water tank, wherein a first pipe and a second pipe are arranged in the sand box longitudinally and vertically; the sand box outside the first pipe and the second pipe is used for filling gravel; a plurality of first through holes are formed in the side wall of the first pipe; a plurality of second through holes are formed in the side wall, approaching the first pipe, of the second pipe; the diameter of the first pipe is greater than the diameter of the second pipe; a water pump is arranged in the water tank; and the water pump is communicated with the second pipe through a first conduit. The invention also discloses an experimental method of researching and removing blocking suspended solids surrounding a seepage well. The experimental device and experimental method of researching and removing blocking suspended solids surrounding a seepage well have the advantages of simple experimental device and the experimental process, easy operation, low research cost, high efficiency, convenience, and relatively higher research value.

Description

Technical field [0001] The invention belongs to the technical field of groundwater artificial recharge, and specifically relates to an experimental device and an experimental method for studying the removal of blocked suspended solids around a seepage well. Background technique [0002] Water is the source of life, and water conservation has become an urgent focus of mankind. Due to the massive exploitation of groundwater, the amount of groundwater storage in some cities has drastically decreased, and the groundwater level has been decreasing year by year. In addition, the hardening of the urban ground destroys the natural water circulation channel. Rainwater falls on the building area or hardened ground and can no longer be recycled in a natural way. Changes in soil moisture content greatly reduce the amount of groundwater formed by natural circulation. For general cities, except for the rainy season, most of the rainfall is moderate rain and light rain. At this time, when the ...

Problems solved by technology

However, the seepage layer of the infiltration well is underground, buried deep, and there is no water to lift it back. Once clogging occurs, it is difficult to remove the clogged suspended matter around the infiltration well, and it is difficult to restore the seepage capacity

[0004] At present, existing infiltration wells often face the problem of difficulty in removing suspended solids. Since there is no water source for lifting, current research is mostly carried out from the prevention and slowing down of suspended solids clogging. The experimental device for removing clogged suspended solids around infiltration wells Therefore, it is of great research value to conduct in-depth research on experimental devices and experimental methods for removing clogged suspended matter around seepage wells
