Interactive rainfall vacuum combined surcharge preloading reinforcement deep soft foundation system and method thereof
The invention discloses an interactive rainfall vacuum combined surcharge preloading reinforcement deep soft foundation system and a method thereof. According to the method, a dewatering well is arranged in vacuum preloading, and an interactive dewatering effect is formed between the dewatering well and a drainage plate by periodically opening and closing a vacuum pump of the dewatering well and communicating the vacuum pump with the atmosphere. In the process that the dewatering well is communicated with the atmosphere, a vacuum pressure gradient is formed for a soil body between the dewatering well and the drainage plate, so that a hydraulic gradient is formed between the dewatering well and the drainage plate, the clogging effect of the drainage plate is greatly improved, and the dewatering effect of the dewatering well is improved. According to the treatment method, the foundation reinforcement of the deep soft soil is greatly improved, the construction period can be shortened, and the construction and maintenance cost is reduced. The method is simple in process and convenient to implement, and can be used for practical engineering.
本发明采用一种交互式降水真空联合堆载预压加固深厚软基系统及其方法。该方法在真空预压中布设降水井，通过周期性开关降水井的真空泵和联通大气，让降水井和排水板之间形成交互式降水的效果。在降水井联通大气的过程中，对降水井和排水板之间的土体形成真空压力梯度，从而在降水井和排水板之间形成水力梯度，较大的改善排水板的淤堵效应，提升降水井的降水效果。该处理方法对深厚软土的地基加固有着较大的改进，可以缩短工期，降低施工维护成本。且该方法工艺简单，实施方便，可用于实际工程。
