High-halogen seawater wall protection slurry for diaphragm wall and preparation method of high-halogen seawater wall protection slurry
The invention discloses high-halogen seawater wall protection slurry for a diaphragm wall and a preparation method of the high-halogen seawater wall protection slurry. The high-halogen seawater wall protection slurry comprises seawater, bentonite, a thickening agent and a dispersing agent, wherein the seawater is high-halogen seawater, and the bentonite is calcium bentonite; the thickening agent is sodium carboxymethyl cellulose; and the dispersing agent is sodium carbonate Na2CO3. The wall protection slurry further comprises a plugging agent, wherein the plugging agent is Portland cement. Themass ratio of the seawater to the calcium bentonite to the thickening agent to the dispersing agent to the plugging agent is (840-880): (125-155): (2.0-4.5): (2.5-4.5): (0-25); and the salinity of seawater is greater than or equal to 40 per mill. The beneficial effects are that high-halogen seawater is adopted for preparing the wall protection slurry for the diaphragm wall, high-quality soil materials are selected, various mud treatment agents are added, and the construction requirements of the diaphragm wall under the conditions of high underground (high-halogen seawater) water level and loose stratum are met; the problem of difficult pulping of the diaphragm wall due to lack of fresh water resources is solved, the cost is saved, and the work efficiency is improved; and the constructionquality is ensured.
一种防渗墙高卤海水护壁泥浆及其配制方法。本发明包括海水、膨润土、增稠剂、分散剂，海水为高卤海水，膨润土为钙基膨润土；增稠剂为羧甲基纤维素钠；分散剂为纯碱Na2CO3；护壁泥浆还包括堵漏剂，堵漏剂为硅酸盐水泥；海水、钙基膨润土、增稠剂、分散剂、堵漏剂的质量比为（840～880）∶（125～155）∶（2.0～4.5）∶（2.5～4.5）∶（0～25）；其中，海水盐度≥40‰。其有益效果是，采用高卤海水制备防渗墙护壁泥浆，选用优质土料和添加多种泥浆处理剂，满足在高地下（高卤海水）水位且松散地层条件下防渗墙的施工要求；解决了防渗墙因淡水资源匮乏导致的制浆难问题，节约成本，提高工效；确保工程质量。
