Underground rainwater filter tank facilitating collection and storage

Abstract

The invention discloses an underground rainwater filter tank facilitating collection and storage. The underground rainwater filter tank comprises a reservoir, waterproof walls are arranged on two sides of the reservoir, a cover plate is mounted at the tops of the two waterproof walls, a water pump is mounted at the top of the cover plate, the bottom of the water pump is connected with a water pipe, a waterproof layer is arranged at the bottom of the reservoir, pack-up blocks are arranged on two sides of the top of the waterproof layer, a supporting plate is mounted at the tops of the two pack-up blocks, a medium sand layer is arranged at the top of the supporting plate, a coarse sand layer is arranged at the top of the medium sand layer, a pebble layer is arranged at the top of the coarsesand layer, the water pipe penetrates the middles of the medium sand layer, the coarse sand layer, the pebble layer and the supporting plate, and a concrete layer is arranged at the bottom of the waterproof layer and fixedly connected with the waterproof layer. Rainwater on the ground surface can be effectively collected and stored into the reservoir through a permeation pipe, water can be effectively purified, and the underground rainwater filter tank is simple in structure and convenient to implement.

Description

technical field [0001] The invention relates to the technical field of rainwater filtration, in particular to an underground rainwater filtration tank convenient for storage. Background technique [0002] Rainwater collection, in a complete sense, should be called "rainwater collection and utilization system". Channel storage and rainwater collection provide rainwater replenishment for greening, landscape water bodies, washing and groundwater sources, so as to achieve the purpose of comprehensive utilization of rainwater resources and water conservation. It has extensive significance in slowing down urban rainwater floods and groundwater level decline, controlling rainwater runoff pollution, and improving urban ecological environment. Rainwater harvesting uses buildings, roads, lakes, etc. to collect rainwater for green space irrigation and landscape water, or build permeable pavements and pave with permeable materials to directly increase the amount of rainwater infiltrati...
