摘要
本次深基坑止水,尝试采用了高压旋喷桩与基坑支护桩结合形成止水帷幕的方法,使高压旋喷桩数由210根减至78根,不权大大减少了施工工作量,而且缩短了工期。经过充分论证和反复试验,以所取得的有效参数进行施工,最终取得成功。
A method for anti-seep in deep foundation pit combine high pressure rotary-jet pile with retaining pile of foundation pit become anti-seep curtain has been tried. It able to reduced high pressure rotary-jet piles from 210 to 78, and also reduce amount of construction and time. Through fully demonstration and repeatedly testing, obtained effective parameters and put to use in construction make issue to final success.
