一、前言地下防渗墙作为水工建筑物防渗措施之一,已被我国广泛应用。我国现有防渗墙造孔开槽的设备型式繁多,但大多数设备结构复杂,操作技术要求较高。一九八四年省水管局在漳州召开三大江堤基防渗技术座谈会,研究了建造堤基防渗 I. Introduction Underground impervious wall as one of the hydraulic structures anti-seepage measures has been widely used in our country. There are many types of equipment for making holes and grooving in existing impermeable walls in China, but most of the equipment has complicated structures and requires high operation techniques. In 1984, the Bureau of Water Resources held a symposium on seepage control technology of the three major river embankment basins in Zhangzhou to study the effect of seepage control
