Vacuum preloading pumping drainage method for ultra-soft soil
The invention relates to a vacuum preloading pumping drainage method for ultra-soft soil, which comprises the following steps: filling a sludge pool with sludge, arranging a vertical drainage plate in the sludge, connecting the vertical drainage plate with a vacuum pump through a drainage pipe which can also be communicated with the atmosphere, and after the vacuum pump is subjected to vacuum preloading pumping drainage for a certain period of time, discharging the vertical drainage plate through the drainage pipe. Closing the vacuum pump and communicating the drainage pipe with the atmosphere, so that the atmosphere enters the drainage pipe to form pressure difference between the surface of the vertical drainage plate and sludge to prevent clogging. After the sludge pool is subjected to vacuum pumping drainage, sludge near the surface of the drainage plate gradually becomes compact, and meanwhile the pressure in the sludge pool is smaller than the atmospheric pressure, the drainage plate is communicated with the atmosphere after vacuum pumping drainage is conducted for a certain time, so that pressure difference is formed on the surface of the drainage plate, and a compact sludge layer on the surface of the drainage plate is pushed to be dispersed or separated; original compact sludge layers are replaced by other sludge with higher flowability, so that the clogging of the drain board is slowed down or prolonged.
本发明涉及一种超软土的真空预压抽排方法，包括在淤泥池内填充淤泥并在淤泥中设置竖向排水板，将竖向排水板通过排水管与真空泵连接，所述排水管还可与大气连通，当所述真空泵真空预压抽排一定时间后，关闭真空泵并将排水管与大气连通使得大气进入排水管在竖向排水板表面与淤泥间形成压差防止淤堵。淤泥池经真空抽排后排水板表面附近的淤泥逐渐变得致密，同时淤泥池内压力小于大气压，本发明通过在真空抽排一定时间后，将排水板与大气连通，使得排水板表面形成压差，推动排水板表面较为致密的淤泥层分散或远离，使得其他流动性更强的淤泥代替原来较为致密的淤泥层，从而减缓或延长排水板的淤堵。
