目前,一些公共建筑如科研楼、办公楼、教学楼的室内楼地面大多设计为现制水磨石,这是因为现制水磨石地面具有美观、整体性好及适用性强的优点。但它由于需现场湿作业,施工难度比较大,尤其是污水排放,往往不被重视,弄得污水满地流淌,既污染了环境,又不利于场容管理。因此,我单位在北京水利电力经济管理学院综合教学楼的现制水磨石施工中,采取了有组织地排放污水方法,即在需现制水磨石楼层的走道内,沿一侧砌一单砖墙,四皮砖高,用25号 At present, most public buildings, such as research buildings, office buildings, and teaching buildings, are mostly designed as existing terrazzo floor. This is because the existing terrazzo floor has the advantages of beautiful appearance, good integrity, and strong applicability. However, due to the need for on-site wet operations, the construction is relatively difficult, and in particular, the discharge of sewage is often not valued, which causes the sewage to flow into the ground, polluting the environment and detrimental to the management of the capacity of the site. Therefore, in the current terrazzo construction of the integrated teaching building of the Beijing Institute of Water Resources and Electric Power Management, our organization has adopted an organized method of discharging sewage, that is, building a single brick wall along one side in the walkway where the existing terrazzo floor is required. Four-brick high, with 25
