Problems solved by technology

[0005] The Abuel-Naga scholar made a heatable plastic drainage board by winding the heating wire on the core board of the plastic drainage board. This kind of hollow tube core board plastic drainage board is not suitable for large-scale application on site. The first heating wire The construction requirements are relatively high, and the on-site construction is likely to cause the electric heating wire to break and cause an open circuit. At the same time, more circuit connections are likely to cause leakage accidents.

Embodiment 1

[0049] A U-shaped circulating hot water consolidation drainage system, including a hot water pool 1, a circulating water pipe 3, and a plurality of hollow circular tube-core plastic drainage plates 4;

[0050] The plastic drainage plate of the hollow round tube core plate includes a hollow round tube core plate 4-1 and a filter membrane 4-2. The hollow round tube core plate can circulate hot water, and the outer surface is provided with longitudinal ribs 4-3 at equal intervals. The filter membrane is wrapped around the hollow circular tube core plate;

[0051] The plastic drainage plate of the hollow circular tube core plate is inserted into the soil body in a manner of folding relative to each other by an inserting plate device to form a U shape, and the openings at both ends of the plastic drainage plate of the hollow circular tube core plate are located on the surface of the soil and connected to the circulating water pipe;

[0052] The circulating water pipes are sequentia...

Embodiment 2

[0061] Such as Figure 3-Figure 7 As shown, a construction method of a U-shaped circulating hot water consolidation drainage system is carried out according to the following steps:

[0062] Step 1. The site is leveled, and a 40cm-50cm thick medium-coarse sand cushion is laid, and the permeability coefficient is required to be greater than 10. -3 m / s.

[0063] Step 2. Hang one end of the plastic drainage plate of the hollow core board on the top of the inserting plate casing, then hang down freely along the inserting plate casing, and bypass the pipe shoe at the bottom of the casing.

[0064] Step 3. In order to protect the plastic drain plate of the hollow core plate from being damaged during the insertion process, a hard plastic protective cover is added to the plastic drain plate of the hollow core plate. The inner bend diameter of the hard protective cover should be five times larger than the plastic drain plate The diameter of the plate.

[0065] Step 4. Mechanically in...

Abstract

The invention discloses a U-shaped circulating hot water consolidated drainage system and a construction method thereof. The U-shaped circulating hot water consolidated drainage system comprises a hotwater tank, a circulating water pipe and a plurality of heating-type plastic drainage plates. The U-shaped circulating hot water consolidated drainage system is simple in structure, core plates of the plastic drainage plates adopt hollow structures, thus hot water can be circulated, on the basis of not influencing the consolidated drainage function of the plastic drainage plates, the plastic drainage plates simultaneously have the heating function, and the plastic drainage plates with the hollow core plates are simple in driving construction and convenient to connect. The plastic drainage plates with the hollow core plates for U-shaped hot water circulating are adopted to increase the temperature of a soil mass in a smearing area around the plastic drainage plates, the consolidated drainage speed is increased, and the consolidation time is shortened, meanwhile, the preconsolidation pressure of soil can be reduced, and the settling volume during foundation treatment is increased.

Description

technical field [0001] The invention belongs to the technical field of civil engineering, and in particular relates to a U-shaped circulating hot water consolidation drainage system and a construction method thereof. Background technique [0002] In the field of soft soil engineering foundation treatment, accelerating soil consolidation by laying plastic drainage boards has become a preferred process for large-area deep soft soil treatment. Especially for the silt after dredging, the water content exceeds 100%, and there is basically no strength. By setting up plastic drainage boards to shorten the drainage path, and then combining vacuum preloading or surcharge preloading, the silt can be drained within 3 to 4 months. After consolidation is completed, the maximum settlement can reach more than 3m. Plastic drainage boards combined with vacuum preloading have been widely used in Tianjin, Huanghua Port, Lianyungang, Shenzhen and other places for reclamation and land reclamati...
