在全国水利化大跃进中,差不多到处可以遇到有在流沙的软地基上修建中、小型水工建筑物的情况,挖基时,常有坑壁坍塌的现象。为了防止坍塌,采用木椿铅丝笼片石固坡法来代替木板椿及钢板椿壁,我们认为是符合多快好省的水利建设方针的。大家知道,在有流沙的软地基上修建中、小型水工建筑物,如水闸、船闸及桥涵等,其唯一困难就是挖基坑的问题,如不采取有效措施,势必造成随挖基 In the great leap forward for water conservancy in China, the construction of medium- and small-scale hydraulic structures on soft foundations of quicksand can be encountered almost everywhere. When the foundation is dug, the pit wall often collapses. In order to prevent collapse, the use of cedar lead wire cage stone solid slope method instead of plywood and steel plate Chun wall, we believe that is in line with the principle of more water conservancy and water conservancy construction. As we all know, the only difficulty in building small and medium-sized hydraulic structures such as sluices, locks and bridges and culverts on soft foundation with quicksand is the problem of digging the foundation pit. If no effective measures are taken,
