A kind of underground underground pipe type submersible replenishment system

Abstract

The invention discloses an underground closed conduit type phreatic water replenishing system. The system comprises a head junction, a closed conduit infiltration system and an operation monitoring system, wherein the head junction and the closed conduit infiltration system are sequentially connected, and the operation monitoring system is used for monitoring the operation condition of the phreatic water replenishing system; the head junction is arranged on the ground surface and used for providing water for replenishment; the closed conduit infiltration system is embedded in a sand gravel vadose zone and used for replenishing the water for replenishment to a water-bearing layer in a leakage mode through an inside and outside water head difference so as to increase groundwater reserves; the operation monitoring system is used for monitoring hydrological and meteorological data of a replenished zone. According to the underground closed conduit type phreatic water replenishing system, the defects of a tube well injection method and a ground infiltration method which are widely applied at the present stage can be compensated, exertion of the groundwater regulation and storage function can be promoted, regional water resources can be reasonably regulated, ground surface runoff is not caused, the evaporation loss is reduced, and the water content of vegetation root layer soil can be effectively controlled; the maintenance difficulty can be reduced, blocking of the water-bearing layer of the replenished zone can be prevented, and the occupied area is reduced.

Description

technical field [0001] The invention relates to a diving replenishment system, in particular to an underground hidden pipe type diving replenishment system, which belongs to the field of artificial replenishment diving devices in underground reservoir engineering. Background technique [0002] Subsurface drip irrigation technology is a high-tech agricultural irrigation technology and one of the typical application forms of micro-irrigation technology. Irrigation water slowly flows out into the nearby soil through the irrigator on the buried capillary, and spreads to the entire root layer by gravity or soil capillary action for crop absorption and utilization. [0003] Subsurface drip irrigation technology does not produce surface runoff during the entire irrigation process, which can minimize the water content of the surface soil and ground evaporation loss, and is convenient for management and control. This provides an important reference for the innovation of diving artif...

Problems solved by technology

The tube well injection method is not limited by terrain conditions, aquitard distribution, and groundwater depth. It occupies a small area, has little water waste, and is not easily affected by factors such as surface climate changes. Larger, the well pipe and aquifer are easy to be blocked, and the requirements for water quality are high, and maintenance is difficult
