Silt rheology vacuum vibration combined dewatering system and method
The invention provides a silt rheology vacuum vibration combined dewatering system and method. The method comprises the steps that vertical and transverse drainage systems are arranged in a to-be-treated area and covered with a sealing film; a vibration quilt equipped with pneumatic vibration units is laid at the upper part of the sealing film, and the vibration units are connected with a high pressure air pump by an air feed pipe network; air exhaust is performed by a vacuum pump through a water sucking channel, water is drained out by utilizing a difference of pneumatic pressure between a vacuum film and the atmosphere, the high pressure air pump is started simultaneously, and the vibration units begin to vibrate under input of high pressure air to drive the vibration quilt to vibrate, to allow a lower soil covering layer to vibrate slightly to perform vibration rheology dewatering on a soft ground; and a vibration rheology dewatering system is moved regularly to allow a treated soft foundation area to settle uniformly. According to the silt rheology vacuum vibration combined dewatering system and method, the treatment efficiency on a silt soft foundation is improved greatly; the energy consumption is low; the mounting and dismounting are easy; the system and method can be used repeatedly in the different to-be-treated areas; the cost is low; the implementation is easy; repeated use is possible; and the multiple effects of high efficiency, economy and safety are achieved.
