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 cos

Embodiment 1

[0031] A kind of thermal drainage consolidation treatment device of soft soil foundation of the present invention, such as figure 1 , figure 2 and image 3 As shown, it includes a pressurized system, a horizontal drainage system and a vertical drainage system. The vertical drainage system includes several heat-conducting plastic drainage boards 1 (the size of ordinary plastic drainage boards can be used), and the heat-conducting plastic drainage board 1 includes a plastic core board 2 and the filter membrane 3 wrapped around the plastic core plate 2, the outer periphery of the plastic core plate 2 is provided with a heat conduction tube 4, the heat conduction tube 4 is connected through a pipe 18 to form a circulation loop, and the water inlet and outlet of the circulation loop are respectively connected to the water circulation heater 5.

[0032] In this specific embodiment, the pressurization system mainly adopts one or more combinations of heap preloading, vacuum preload...

Embodiment 2

[0037] The invention relates to a thermal drainage consolidation treatment method for soft soil foundation. The method is based on drainage consolidation methods such as surcharge preloading and vacuum preloading, adding heat conduction pipes 4 to the two sides and the bottom of the plastic drainage board to form heat conduction Plastic drainage board 1, and after all heat-conducting plastic drainage boards 1 are set up, connect the heat-conducting pipes 4 of all heat-conducting plastic drainage boards 1 into a circulation loop, and then connect to the water circulation heater 5 to form a closed thermal circulation system . Turn on the water circulation heater 5, heat the water flow to 70-90°C, open the water inlet valve 10 and the water outlet valve 11, and start the water circulation heater 5, so that the high-temperature water flow circulates in the heat conduction pipe 4, and the soil around the heat conduction pipe 4 for continuous heating, such as figure 1 , figure 2 ...

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...
