混凝土地下连续墙常用于要求防渗的结构物。结构类型不同,防渗要求不同。本文旨在讨论混凝土地下连续墙的渗水性问题。墙体的渗水性混凝土是在膨润土泥浆护壁的情况下用导管浇灌的。这个浇灌方法要求混凝土的流动性要大,其稠度以塌落度表示应为150～200毫米。混凝土的浇灌与灌浆类似:混凝土不经夯实和振捣,完全靠自重达到密实。 Concrete diaphragm walls are often used for structures that require anti-seepage. Different types of structures, different requirements for seepage. The purpose of this paper is to discuss the seepage problem of concrete diaphragm walls. The seepage concrete of the wall is watered with a conduit in the case of bentonite mud wall protection. This method of watering requires the concrete to have a large mobility, and its consistency should be 150 to 200 mm in terms of slump. The pouring of concrete is similar to that of grouting: concrete is compacted and vibrated, and it is completely densified by its own weight.
