Local dynamic balance dewatering and drainage construction method for deep foundation pit
The invention discloses a deep foundation pit local dynamic balance dewatering and drainage construction method which is mainly used for solving the problems that the water level of a local deep foundation pit descending plate area is high, and dewatering is needed in foundation pit operation. The dewatering and drainage construction method is arranged at the bottom of a foundation pit, a concrete sealing layer is arranged on the upper portion of the foundation pit to form an independent dewatering and drainage system, water on the lower portion of the sealing layer is drained out of the foundation pit through the dewatering and drainage construction method, dynamic balance of the water level on the lower portion of the foundation pit is achieved, and a waterless operation environment is provided for the upper portion of the sealing layer. The problem of dewatering in a local deep foundation pit descending plate area can be effectively and rapidly solved, a waterproof curtain does not need to be arranged, dynamic balance of the water level at the bottom of a foundation pit is achieved through effective combination of equipment such as a seepage and drainage blind pipe, a drainage pipe, a booster pump and a sealing layer, and compared with a traditional dewatering mode, the construction steps are reduced, the construction period is shortened, and the foundation construction quality is improved; and the benefits of reducing cost and increasing efficiency are achieved.
本发明公开了一种深基坑局部动态平衡降排水施工方法主要是针对局部深基坑降板区域水位较高，基坑作业需要降水时使用；降排水施工方法设置在基坑底部，上部设置混凝土封闭层，形成独立的降排水体系，封闭层下部的水通过降排水施工方法降排至基坑外，实现基坑下部水位动态平衡，给封闭层上部提供无水的作业环境；能够有效快速解决局部深基坑降板区域降水的问题，无需设置止水帷幕，通过渗排水盲管、排水管、增压泵、封闭层等设备的有效结合，实现基坑底部水位的动态平衡，和传统的降水方式比较，减少了施工步骤、缩短了工期、提升了基础施工质量，实现降本增效的效益。
