Description
Technical field
The present invention relates to a kind of sand base brick and preparation method thereof and by the assembled sand Ji Lvshuijing of sand base brick.
Background technology
At present, the water resources shortage in the whole world, lack of water is local a lot of all over the world.In the area of a lot of lacks of water, all there are shortage problem in people's drinking water, life industrial water.Especially in the last few years, because climate reasons, the precipitation in a lot of areas was lack of standardization, caused the long-time arid in these areas.In order to solve these regional water shortage problems, a lot of regional sink wells, but because the also very shortage of these regional underground water, the well of therefore beating often leans on rainwater, river to wait and keep the water yield, and these water are not suitable for drinking not through filtration; Although water can become limpider at long-time post precipitation, after the time was long, the water capacity is prone to foul, and was rotten; And the water in the well permeates the ground soon, or evaporates, and can not utilize rainwater well like this.
In order effectively to utilize water resources such as rainwater or river; Usually adopt the water purification water storage system to utilize once more with rainwater or river collection and after purifying; And for rainwater or river etc. is collected in the tank; And will from tank, take out through the water after purifying, need in the water purification water storage system, build well, and the borehole wall of such well all need have effect permeable and filtration.Yet; In the prior art, well has a variety of, for example; Sewer with sink hole, underground water-carriage system with escape pit etc.; But the borehole wall of this well all is to utilize steel concrete to build to form mostly, does not all have effect permeable and filtration, can not use as the well in the above-mentioned water purification water storage system.
Therefore, how to obtain to realize that the permeable drainage well of filtration of realizing again remains a technical problem that needs to be resolved hurrily.
Summary of the invention
The objective of the invention is to address the above problem, provide a kind of and can realize the permeable sand base brick that can realize filtration again.
Another object of the present invention is to provide a kind of preparation method of sand base brick.
A further object of the present invention is to provide a kind of sand Ji Lvshuijing.
Inventor of the present invention is through discovering; Through the sand based composition and use thereof in packaging compression moulding that will contain silica sand and cementing agent is the sand base brick of void content in the 10-50% scope; Again through this sand base brick is assembled into sand Ji Lvshuijing; Can address the above problem well, realize performance permeable and filtration, and have good intensity.
The invention provides a kind of sand base brick; At least one brace summer that this sand base brick comprises inboard brick body, outside brick body and between inboard brick body and outside brick body, is used for inboard brick body is fixedly connected with outside brick body; It is characterized in that inboard brick body, outside brick body and brace summer are structure as a whole, through containing the sand based composition and use thereof in packaging moulding of silica sand and cementing agent; Adhesive cures is obtained, and the porosity of said inboard brick body and outside brick body is 10-50%.
The present invention also provides a kind of drainage well, it is characterized in that, the drainage well comprises the borehole wall, shaft bottom and the space that is surrounded by the borehole wall and shaft bottom, and at least a portion of the borehole wall is assembled by above-mentioned sand base brick.
Sand base brick of the present invention obtains through the sand based composition and use thereof in packaging compression moulding that will contain silica sand and cementing agent, and makes the void content of sand base brick be controlled at 10-50%, has realized that sand base brick has performance permeable and filtration, and its coefficient of permeability can be reached for 1-6cm/s.And; The shape of at least one brace summer that sand base brick is shaped to comprise inboard brick body, outside brick body and between inboard brick body and outside brick body, is used for inboard brick body is fixedly connected with outside brick body; Reduced the weight of sand base brick greatly, simultaneously, when being assembled into sand base well by this sand base brick; Can between inboard brick body and outside brick body, form cavity, be used to fill the material that other has filtration.In addition, sand base brick of the present invention obtains through the sand based mixtures compression moulding that will contain silica sand and cementing agent, has significantly improved the compressive strength of sand base brick, and its compressive strength can reach 10-50MPa.
