Abstract

The invention discloses an underground cascade reservoir and a method for constructing the same, wherein, the underground cascade reservoir comprises at least two grooves, impermeable geomembranes paved at the bottoms of the grooves; a cutting undercurrent filter pipe arranged along the top of the impermeable geomembranes of the grooves, control valve inlet wells arranged at the downstream ends of the cutting undercurrent filter pipes; an impervious wall arranged at the downstream ends of the grooves, wherein, the control valve inlet wells are orderly connected by conduits being connected orderly. The construction method comprises the following steps that: (1) the grooves are dug; (2) impermeable parts are prepared; (3) the cutting undercurrent filters are paved; (4) the control valve inlet wells are arranged; (5) the conduits are paved. The invention has the advantages that: the underground cascade reservoir is constructed under the condition of the natural gradient of the natural hypsography of the river, and is positioned in the seasonal mountains and rivers and utilizes the natural gradient of the mountains and rivers to collect the natural water resources maximumly.

Description

technical field [0001] The invention relates to a reservoir and a construction method thereof, in particular to an underground cascade reservoir and a construction method thereof. Background technique [0002] With the development of society and the increasing population, people's demand for water is increasing day by day, and the contradiction between water demand and water supply capacity is increasing year by year. As an important strategy and means to optimize the allocation of water resources and improve the carrying capacity of water resources, underground reservoirs It is one of the current research hotspots in the field of water conservancy at home and abroad. [0003] Judging from the existing groundwater reservoirs, most of them use the water balance method to regulate and store groundwater. The biggest defect of this method is that it cannot guarantee the continuous supply of groundwater. Patent CN1116261A discloses a method of storing water for agricultural irri...
