Abstract

The present invention discloses a water circulation type foundation heating device and a construction method of dewatering of a soft soil foundation using the same. The water circulation type foundation heating device comprises an electric heating furnace and a plurality of U-shaped steel pipes. The U-shaped steel pipes are driven into a soft soil foundation. A circulating water outlet and a circulating water return inlet of the electric heating furnace sequentially connect water inlets and water outlets of all the U-shaped steel pipes in series to form a water circulation loop. During construction, the water circulation type foundation heating device is combined with a vacuum preloading method; water at the later period of foundation consolidation is mainly discharged in the gaseous form; thus, dewatering and solidification of soil are accelerated, and the strength of the consolidated foundation is improved with a reduction in post-construction settlement and a good foundation treatment effect.

Description

technical field [0001] The invention belongs to the technical field of large-area soft soil foundation treatment, in particular to a water circulation type foundation heating device and a construction method for dewatering soft soil foundation using the device. 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 s...
