Cement soil diaphragm wall and construction method thereof
The invention provides a cement soil diaphragm wall and a construction method thereof, and relates to the technical field of water conservancy projects. The cement soil diaphragm wall comprises a wall body, the wall body comprises first cement columns and second cement columns, the number of the second cement columns is two times that of the first cement columns, the sections between the adjacent first cement columns and second cement columns are cut, and the sections between the second cement columns are cut. Each of the first cement column and the second cement column is prepared by mixing cement paste, original soil, a preservative and a water reducing agent, the cement paste is prepared by mixing and stirring Portland cement and water, the preservative is one of fly ash or mineral powder, and the diameter of the first cement column is larger than that of the second cement column. According to the cement soil diaphragm wall and the construction method thereof, the preservative is added to the cement paste, such that the corrosion resistance of cement can be easily improved so as to prolong the service life of the diaphragm wall, and the industrial waste fly ash is comprehensively utilized so as to provide the green environmental protection significance.
本发明提供一种水泥土防渗墙及其施工方法，涉及水利工程技术领域。该水泥土防渗墙，包括墙体，所述墙体包括第一水泥柱和第二水泥柱，所述第二水泥柱的数量是第一水泥柱数量的两倍，并且相邻第一水泥柱与第二水泥柱之间、第二水泥柱与第二水泥柱之间的截面均为相割，所述第一水泥柱、第二水泥柱均由水泥浆、原土、防腐剂和减水剂混合制成，所述水泥浆由硅酸盐水泥和水混合搅拌制成，所述防腐剂为粉煤灰或矿粉中的一种，所述第一水泥柱的直径大于第二水泥柱的直径。通过在水泥浆料中添加防腐剂，有利于提高水泥的防腐性能，从而提高防渗墙的使用寿命，同时这种防腐方法还综合利用了工业废料—粉煤灰，具有绿色环保的意义。
