Abstract

The invention discloses a foundation treatment system based on electric heating drainage plates. The foundation treatment system comprises the electric heating drainage plates, wherein each of the electric heating drainage plates comprises a plastic core plate, two layers of filter cloth wrap the periphery of the plastic core plate, and an electric heating wire is arranged in the interlayer between the two layers of filter cloth; the electric heating drainage plates are vertically arranged in the foundation, the head parts of the electric heating drainage plates are bound on filter tubes whichare transversely arranged, a pressure guiding and shunting device is arranged on the foundation, and water inlets of the pressure guiding and shunting device communicate with the filter tubes; a sandcushion is laid on the foundation, the water inlets of the pressure guiding and shunting device, the filter tubes and the head parts of the electric heating drainage plates are laid in the sand cushion, a heat preservation layer is laid on the sand cushion, a sealing film is laid on the heat preservation layer, the pressure guiding and shunting device penetrates through the sealing film, and thepressure guiding and shunting device is isolated from the sealing film; and a power supply wire of the electric heating wires of the electric heating drainage plates is led out of the sealing film through a film penetrating device and is connected with an external power supply, the edges of the sealing film is pressed into film pressing grooves, so that a closed vacuum pre-pressing system is formed.

Description

technical field [0001] The invention belongs to the technical field of large-area soft soil foundation treatment, in particular to a foundation treatment system based on an electric heating drainage board and a construction method thereof. Background technique [0002] The prominent feature of the newly dredged supersoft soil is that the surface strength is extremely low, and its foundation treatment is a recognized problem at home and abroad. This kind of foundation is generally reinforced by drainage consolidation method. In my country, surcharge preloading method, vacuum preloading method or vacuum combined surcharge preloading method are mainly used. However, the conventional drainage consolidation method is used to reinforce the newly dredged and filled mud and floating mud. After 3 to 5 months of preloading and reinforcement, the settlement of the foundation is relatively significant, often exceeding the theoretical calculation by a lot, but the strength after reinforc...
