防渗墙高卤海水护壁泥浆技术研究

Study on Slurry Technology of High Brine Seawater Wall Protection for Cutoff Wall

中东地区淡水资源稀缺,地域辽阔,交通运输困难,淡水供应难度较大,且市场上淡水价格较高,沙特萨拉曼国王国际港项目防渗墙施工工程量大,淡水需求量大,合同工期紧,地下水位高(约1.8 m)地质条件差,致使防渗墙造槽时极易发生塌漏与孔洞,工程质量、安全与工期得不到保证。因此,防渗墙护壁泥浆质量的优劣成为该工程成败的关键。若采用海水制浆,将有效解决施工淡水资源匮乏的问题,为施工提供便利条件,同时也能降低施工成本。

In the Middle East, the fresh water resources are scarce, the territory is vast, the transportation is difficult, the fresh water supply is difficult, and the price of fresh water is high in the market. The impervious wall construction of King Salaman international port project in Saudi Arabia has a large amount of work, a large demand for fresh water, a tight contract period, a high groundwater level(about1.8 m) and poor geological conditions, resulting in the collapse and leakage of the impervious wall and the hole, so the project is difficult quality, safety and construction period are not guaranteed. Therefore, the quality of slurry is the key to the success of the project. If seawater pulping is used, it will effectively solve the problem of shortage of fresh water resources for construction, provide convenient conditions for construction, and reduce the construction cost.
