Sand-based brick and sand-based water filter well

Abstract

The invention provides a sand-based brick, which comprises an inside brick body, an outside brick body and at least one supporting beam which is located between the inside brick body and the outside brick body and is used for fixedly connecting the inside brick body and the outside brick body, wherein the inside brick body, the outside brick body and the supporting beam are of an integrated structure, the sand-based brick is obtained by molding a sand-based composition containing silicon sand and binders and curing the binders, and the porosity of the inside brick body and the outside brick body is 10-50%. The sand-based brick is obtained by pressing and molding the sand-based composition containing the silicon sand and the binders, the porosity of the sand-based brick is controlled to be 10-50%, thus, the sand-based brick has the properties of permeating water and filtering and has the water permeability coefficient capable of reaching 1-6cm / s. The invention further provides a water filter well, which comprises a well wall, a well bottom and a space defined by the well wall and the well bottom, and at least one part of the well wall is formed by assembling the sand-based bricks disclosed by the invention.

Description

technical field [0001] The invention relates to a sand-based brick, a preparation method thereof and a sand-based water filter well assembled from the sand-based bricks. Background technique [0002] At present, the global water resources are scarce, and there are many places lacking water all over the world. In many water-scarce areas, people's drinking water, domestic and production water are in short supply. Especially in recent years, due to climatic reasons, precipitation in many areas has been irregular, resulting in long-term drought in these areas. In order to solve the water shortage problem in these areas, water wells are drilled in many areas, but because the groundwater in these areas is also in short supply, the wells drilled often rely on rainwater, river water, etc. to maintain the water volume, and the water is not filtered and is not suitable for drinking; although The water can become clearer after a long period of precipitation, but after a long time, th...

Problems solved by technology

However, in the prior art, there are many kinds of wells, for example, sewage wells for sewers, safety wells for underground water delivery systems, etc., but the well walls of such wells are mostly constructed of reinforced concrete, which do not have water permeability. and filtering, it cannot be used as a well in the above-mentioned water purification storage system
