我局二处一队利用单头潜水电钻加防扭架比较成功地成型了一条长6.3米、宽60厘米、深13米的地下连续墙槽。成槽20余天,槽壁未发现塌孔。此工艺的特点是利用现有设备,工艺简单,提供了单头潜水电钻成槽的经验。问题是单钻头进度较慢。 A team of two teams using the single-head submersible drill and anti-twisting frame successfully formed a continuous underground wall groove with a length of 6.3 meters, a width of 60 centimeters, and a depth of 13 meters. Into the groove more than 20 days, the wall did not find collapse. This process is characterized by the use of existing equipment, the process is simple, and provides the experience of single-head submersible drilling into the groove. The problem is that single-bit progress is slower.
