水冲法施工技术是一种高效率的地下造孔新工艺,运用本法可以高速建造各种断面(如圆形、方形、长方形等)的地下孔、槽.水冲法造孔是利用高速密集的水流束,通过一种特制的水力造孔机械——“带罩的高压水冲枪”去完成,而不是利用机械去冲击、切削、挖掘地下孔槽,因而使造孔速度成倍增长,提高了工效,缩短了工期,降低了造价,从而获得较好的经济效果. 一、水冲法施工技术的创造与应用 水冲法施工技术是我局1965年在山西汾河二坝工程施工中,根据基础防渗工程的需
The water-blasting construction technique is a new efficient underground hole-making technology, which can be used to build underground holes and troughs of various sections (circular, square, rectangle, etc.) Dense jet streams are made through a special hydraulic hole-forming machine, a “high-pressure water gun with a hood,” instead of mechanically striking, cutting and digging underground slots, thereby doubling the rate of pore formation , Improve the work efficiency, shorten the construction period, reduce the cost, so as to obtain better economic results.First, the water hammer construction technology to create and apply water scouring construction technology is our bureau in 1965 in Shanxi Fen River dam construction In accordance with the needs of the basic seepage control project
