透水砖的制造与施工技术研究

Study on Manufacturing and Construction Technology of Permeable Bricks

透水砖作为一种新兴的建筑材料,具有透水功能,可以减少城市内地表径流量,缓解城市内涝,受到越来越多的关注。透水砖的种类不同,其制造工艺也有所差异。透水砖的透水性能与抗压强度相互制约,对其应用造成了一定影响。透水砖的施工工艺要求其基层具有透水性,使得透水砖铺装层整体具有透水功能。透水砖也在不断发展,砂基透水砖作为一种新型的透水砖,孔隙不易被阻塞,透水效果坚持时效长。

As a new building material,permeable bricks have the function of water permeability,which can reduce the surface runoff in urban areas and ease the urban hustle and it get more and more attention. Different kinds of permeable bricks,their manufacturing process is also different. The pervious performance and compressive strength of the permeable bricks are mutually restricted,which has a certain impact on their application. The construction process of the permeable brick requires that the base layer has water permeability,so that the permeable brick paving layer has a water-permeable function as a whole. Permeable bricks also have been continuously developed. As a new type of pervious brick,sand-based permeable bricks are not easy to be blocked,and the permeation effect persists for a long time.
