Fabricated underground water taking device applicable to civil air defence space and construction method

Abstract

The invention discloses a fabricated underground water taking device applicable to a civil air defence space and a construction method. The fabricated underground water taking device comprises a tubewell passing through an underground clay stratum and a water-containing layer; the tube well is provided with filtering holes on the tube wall of the water-containing layer; a pump room is arranged above the tube well; a water manifold is arranged in the tube well; a head part of the water manifold is positioned in the tube well on the water-containing layer section; a tail part of the water manifold is positioned in the pump room, and is connected with a water taking pump; underground water pumped by the water taking pump flows into an inner pool via the water manifold; a valve is mounted atthe water outlet end of the water manifold; an outer pool is arranged on the periphery of the inner pool; a purification wall is arranged between the inner pool and the outer pool; and purification bins are arranged at intervals in the purification wall. According to the invention, water taking, water purification and storage are integrated, a case of no available water when an external water source is cut off in an emergency is avoided, and meanwhile, a purification device can effectively ensure water quality safety of underground water. The fabricated underground water taking device is applicable to a civil air defence underground structure of which site hydrogeological conditions accord with wartime water use requirements.

Description

technical field [0001] The invention relates to the fields of civil engineering and underground engineering, in particular to an integrated device for extracting, storing and purifying groundwater in an underground air defense space. Background technique [0002] Under the current construction system of civil air defense projects in our country, most of the civil air defense projects use water storage tanks to be built before the battle, and use municipal tap water (urban water source) to fill water for wartime equipment, personnel drinking, living and decontamination water, which is commonly referred to as There is no reliable internal water source and no protected external water source. The main advantage of this water supply method is that the water quality and quantity of municipal tap water can be easily guaranteed, and the safety and economy are relatively good. However, the drinking water quality standards and water quotas implemented during the war were lower than u...

Problems solved by technology

[0004] The present invention aims at the problems existing in the supply of water sources outside the existing civil air defense projects, and proposes an assembled underground water intake device suitable for civil air defense spaces, so as to solve the technical problem that the emergency water supply outside the existing civil air defense projects cannot ensure water safety.
