当用干垒混凝土砌块垒砌较高挡土墙时,通常需要将墙后方挖开,以便在挡墙施工时铺设土工格栅(或称为:土工布),开挖量和宽度取决于墙高等因素。因此,混凝土砌块干垒挡土墙应用时,其土方开挖量和回填量大,是该种挡土墙结构的一大问题。如何在那些场地受限或无法选择开挖加铺土工格栅的地方,通过选择特殊的施工方法来实现混凝土砌块干垒挡墙的应用呢?填充无砂大孔混凝土不但可以提高干垒挡墙的抗侧向力的能力,还有助于提升干垒挡墙特有的透水生态化功能。
When building a higher retaining wall with a dry-wall concrete block, it is usually necessary to dig the rear of the wall so that a geogrid (or geotextile) is laid during construction of the retaining wall, the amount of excavation and the width depend on Wall high factors. Therefore, the application of dry block retaining wall of concrete block, the earth excavation volume and backfill volume, is a major problem of the retaining wall structure. How to apply the special construction method to realize the application of dry block retaining wall of concrete block where those sites are limited or unable to choose to excavate and populate the geogrid? The filling of the non-sand macroporous concrete can not only improve the dry block The ability of the wall to resist lateral forces also helps to enhance the water-permeable ecological function unique to the drywall.
