Device and method for collecting, treating and saving building water resources

Abstract

The invention relates to the field of building construction, in particular to a device and method for collecting, treating and saving building water resources. The device comprises a foundation pit body, a filter tank, a main water storage tank and an auxiliary water storage tank, wherein at least one circle of water collecting ditches is arranged at the edge of the foundation pit body, the watercollecting ditches are arranged in a hollow-square shape, and the plurality of circles of water collecting ditches are coaxially arranged at the outer edge of the foundation pit body; the filter tankis arranged on the side of the foundation pit body, and a first water pump is arranged between the filter tank and the foundation pit body; the first water pump pumps out water accumulated in the foundation pit body, and sand and gravel are filtered at the filter tank; the main water storage tank communicates with the filter tank for water storage and backfilling and water injection of the foundation pit body; and the auxiliary water storage tank communicates with the main water storage tank to provide water for construction facilities and municipal fire fighting systems. Rainwater is collected by the water collecting ditches, and the collected rainwater is filtered and then is recharged to surrounding strata to maintain balance of water system supply, so that the purpose of water recycling is achieved.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a device and method for collecting and processing building water resources and saving water. Background technique [0002] In order to ensure the safety and stability of the underground space formed by the excavation of the ground during the construction of the underground structure, the retaining structure, groundwater control, environmental protection and other measures are called foundation pit engineering. Foundation pit engineering is a system engineering integrating geological engineering, geotechnical engineering, structural engineering and geotechnical testing technology. Its main content: engineering survey, support structure design and construction, earthwork excavation and backfill, groundwater control, information construction and surrounding environmental protection, etc. The simplest and most economical way to construct a foundation pit is to excavate on a larg...
