Hot-water draining consolidation processing device and hot-water draining consolidating processing method for soft soil foundation

Abstract

The invention discloses a hot-water draining consolidation processing device and a hot-water draining consolidating processing method for soft soil foundation. The device provided by the invention comprises a pressure system, a horizontal water draining system and a vertical water draining system; the vertical water draining system comprises a plurality of heat conduction plastic water draining plates; each heat conduction plastic water draining plate comprises a plastic core plate and a filter membrane; heat conduction pipes are arranged at the periphery of the plastic core plate; all the heat conduction pipes are connected to form a circulating loop through a pipeline; and a water inlet and a water outlet of the circulating loop are respectively connected with a water circulation heater. The method provided by the invention mainly comprises the steps of: leveling up a site, laying a horizontal water draining sand cushion, excavating pipe slots to arrange a vacuum water draining filter pipe, connecting the vacuum water draining filter pipe with a vacuum pump, inserting the heat conduction plastic water draining plates, laying a seal membrane and a piece of geotextile, starting the water circulation heater and the vacuum pump, vacuumizing and performing preloading. The device and the method provided by the invention have the advantages that the construction period is effectively shortened, sedimentation after the construction is reduced, the process is simple, and the operation is convenient.

Description

technical field [0001] The invention relates to the technical field of soft soil foundation treatment, in particular to a thermal drainage consolidation treatment method for soft soil foundation and a treatment device thereof. Background technique [0002] The soft soil foundations of marine, lacustrine and river deposits are widely distributed in the southeast coast and inland of my country, which are characterized by large water content, high compressibility, low strength, poor water permeability, and in many cases are deeply buried, and the bearing capacity of the foundation is stable. Sex often does not meet engineering requirements. Therefore, the soft soil foundation needs to take treatment measures. The drainage consolidation method is one of the effective methods to deal with the soft clay foundation. The weight of the building itself is gradually loaded in groups, or before the building is built, the preload is loaded on the site first, so that the pore water in the...

Problems solved by technology

Therefore, in order to speed up the consolidation of the foundation, the surface load must be increased, but it is easy to damage the structure of the soft soil, resulting in a decrease in the permeability coefficient and slowing down the pore water pressure, which in turn leads to the extension of the drainage consolidation time of the foundation and affects the construction period. , and even project cost

Therefore, the limitations of the existing drainage consolidation treatment methods for soft soil foundations using ordinary plastic drainage boards are mainly due to the failure to fundamentally improve the horizontal penetration and consolidation speed of the soil, and the horizontal consolidation speed of soft soil foundations is still slow. , it takes a long time to strengthen the soft soil foundation
