Vibration rod and vacuum preloading combined soft soil foundation reinforcing structure and method
The invention discloses a vibration rod and vacuum preloading combined soft soil foundation reinforcing structure and method, and belongs to the technical field of civil engineering, and the vibration rod and vacuum preloading combined soft soil foundation reinforcing structure comprises a drainage channel built in a soft soil foundation; the drainage channel comprises a drainage belt inserted in the soft soil foundation; a sand cushion layer is laid on the upper surface of the soft soil foundation; the upper end part of the drainage belt is positioned in the sand cushion layer; a sealing film is laid on the upper surface of the sand cushion layer, and the laying area of the sealing film is larger than the area of the soft soil foundation. Sealing ditches are formed in the periphery of the soft soil foundation, the sealing film extends downwards into the sealing ditches, and the positions, above the sealing film, in the sealing ditches are filled with clay; the vacuum preloading discharge system comprises a filter pipe embedded in the sand cushion layer and a main drainage pipe connected with the filter pipe, and the main drainage pipe is connected with a vacuum pump; the vibration rod system comprises a vibration rod which is connected with the vibrator. According to the method, the vacuum preloading efficiency can be improved, dissipation of ultra-static pore pressure is accelerated, discharge of pore water in the soil body and soil body solidification are accelerated, and the vacuum preloading reinforcement time is shortened.
本发明公开了一种振动杆联合真空预压的软土地基加固结构及方法，属于土木工程技术领域，包括建立在软土地基中的排水通道；排水通道包括插装在软土地基内的排水带；在软土地基的上表面铺设有砂垫层；排水带的上端部位于砂垫层内；砂垫层的上表面铺设有密封膜，密封膜的铺设面积大于软土地基的面积；在软土地基的四周开设有密封沟，密封膜下延至密封沟内，在密封沟内，密封膜的上方填充有粘土；真空预压排放系统包括埋设在砂垫层内的滤管、与滤管连接排水总管，排水总管连接真空泵；振动杆系统包括振动杆，振动杆与振动器连接。本发明能够提高真空预压的效率，加速超静孔压的消散，加快土体内孔隙水的排出和土体固结，缩短真空预压加固时间。
