Vacuum combined surcharge preloading reinforced soft foundation system
The invention discloses a vacuum combined preloading reinforced soft foundation system, and relates to the field of building foundations, the vacuum combined preloading reinforced soft foundation system comprises a soft soil foundation, a medium-coarse sand cushion layer, a vacuum sealing layer, a preloading earthwork layer and a drainage device which are sequentially arranged from bottom to top, and a sealing gap is formed between the vacuum sealing layer and the medium-coarse sand cushion layer; the drainage device comprises a drainage filter pipe, a plastic drainage belt and a vacuum pump, the drainage filter pipe is laid on the inner side of the sealing gap, and the vacuum pump is located outside the sealing gap and connected with the drainage filter pipe; the main body part of the plastic drainage belt is inserted into the soft soil foundation, and the upper end of the plastic drainage belt extends out of the soft soil foundation and is connected with the drainage filter pipe; the drainage filter pipe is sleeved with a spiral steel wire framework, the spiral distance of the spiral steel wire framework is larger than the width of the plastic drainage belt, and the outer end of the plastic drainage belt wraps the peripheral face of the drainage filter pipe and is located between spiral coils of the spiral steel wire framework. According to the vacuum pumping device, the water filtering holes of the drainage filtering pipe can fully play a role in ventilation in the vacuum pumping process.
本申请公开了真空联合堆载预压加固的软基系统，涉及建筑地基的领域，其包括从下往上依次设置的软土地基、中粗砂垫层、真空密封层、堆载预压土方层和排水装置，真空密封层与中粗砂垫层之间形成密封间隙；排水装置包括排水滤管、塑料排水带和真空泵，排水滤管铺设于密封间隙内侧，真空泵位于密封间隙外，且与排水滤管连接；塑料排水带的主体部位插设于软土地基，塑料排水带的上端伸出软土地基，且与排水滤管连接；排水滤管套设有螺旋钢丝骨架，螺旋钢丝骨架的螺旋间距大于塑料排水带的宽度，塑料排水带的外端包覆排水滤管的外周面，且位于螺旋钢丝骨架的螺旋线圈之间。本申请能够使排水滤管的滤水孔能够在抽真空的过程中充分发挥通气的作用。
