Abstract
Description
Technical Field
[0001] The invention relates to the technical field of soft foundation reinforcement, and in particular to a soft foundation reinforcement device. Background Art
[0002] Soft foundation mainly refers to the foundation composed of silt, silty soil, backfill, miscellaneous fill or other highly compressible soil. The soft foundation of coastal shallow soft soil or small hydraulic structure is mainly composed of silt sediments with high natural water content, large porosity and low bearing capacity and a small amount of humus. It is deposited in a static water or slow flowing water environment. Its natural water content is greater than the liquid limit, and its natural porosity is greater than 1.0. It has engineering characteristics such as high water content, low permeability, low shear strength, high compressibility and slow consolidation speed, high organic matter content and thixotropy. The construction of structures on soft foundations is prone to settlement, cracking, instability and other problems, and foundation treatment is necessary.
[0003] The functions of soft foundation treatment include improving foundation permeability, enhancing foundation density and soil shear strength, and enhancing foundation stability. In engineering, soft foundations can be divided into deep soft foundations and shallow soft foundations according to thickness. For coastal shallow soft soil or soft foundations of small hydraulic structures, deep soft foundations can be treated by pile foundation method, such as sandstone piles, cement soil mixing piles, reinforced concrete piles, etc.; shallow soft foundations can be treated by cushion method, reinforcement method, prefabricated concrete short piles, pine wood piles, etc. Sandstone piles and cushion method are both replacement methods. The former uses vibration or sinking pipe to squeeze sand and gravel into the soft foundation to form dense sandstone piles; the latter removes part or all of the soft soil layer, then replaces it with materials with greater strength and compacts it to meet the foundation bearing capacity requirements. Cement soil mixing piles use special deep mixing machinery to inject cement into soft soil, and mix it with soft soil to form high-strength cement soil piles. Reinforced concrete piles are divided into cast-in-place concrete piles and precast concrete piles. The length and diameter of cast-in-place piles can be flexibly adjusted; precast piles can be made into prestressed piles with high pile strength. The reinforcement method usually involves burying geotextiles with good tensile properties in the soil to improve the strength and stability of the foundation. The pine pile method is an ancient foundation treatment method with the characteristics of easy material acquisition and simple construction.
[0004] When the foundation is shallow and soft, the amount of excavation and filling required for cushion construction is large, and the construction period and cost are also long. Compared with the pinewood pile method, the concrete prefabricated short pile method has a large load capacity and strong adaptability, but the investment is large, and a diesel pile driver must be used, which is not convenient for the machine to enter the site, and the requirements for the construction site are high; although the latter has a lower load capacity than the former, it is better in terms of low investment and simple construction. In addition to diesel pile drivers, hydraulic excavators can also be used for static pressure pile sinking, which has fewer restrictions on the site.
[0005] Traditional pine piles use the pile body to replace the original soil to form a composite foundation. On the one hand, it has a compacting effect on the soil between the piles during the construction process, compacting the soil to reduce compressibility and increase the bearing capacity of the soil between the piles. On the other hand, the composite soil can uniformly distribute stress, increase the pressure diffusion angle, increase the bearing capacity of the foundation, and reduce the amount of foundation settlement. However, traditional pine piles cannot reduce the moisture content of the original soil when treating soft foundations, and the settlement and deformation period of the soil is long. Summary of the invention

[0028] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.
[0029] Example 1
[0030] Reference Figure 1-Figure 2 , provides a soft foundation reinforcement device, including a pile body 100, which can be inserted into the soft foundation; a drainage channel 200, which is arranged outside the pile body 100; wherein the drainage channel 200 can drain water in the soft foundation;
[0031] The pile body 100 is inserted into the soft foundation to strengthen the foundation, and the drainage channel 200 plays a supporting role and discharges the water seeping from the soft foundation upward, so that the drainage channel 200 has a drainage and hydrophobic function, discharges the moisture in the original foundation soil, and strengthens the bearing capacity of the foundation.
[0032] Furthermore, the drainage channel 200 is a drainage board, and the material of the drainage board is a mixture of polypropylene and polyethylene;
[0033] In this embodiment, the drainage board is actually a finished plastic core board formed by extrusion. The plastic core board is made of a mixture of polypropylene and polyethylene, and its cross-section is a parallel cross. The cross-sectional dimensions of the drainage board are 100 mm wide and about 5 to 8 mm thick. It is the skeleton and channel of the drainage channel 200. Multiple groups of drainage boards are distributed at four symmetrical corners on the outside of the pile body 100 and are adhered to the pile body 100 with adhesive.
[0034] Furthermore, the outer side of the drainage channel 200 is coated with a filter layer 300; a protective layer 400 is provided between the filter layer 300 and the drainage channel 200;
[0035] The protective layer 400 can reinforce the drainage board, and the filter layer 300 can filter the silt to prevent the silt from entering the drainage channel 200 and clogging it.
[0036] Furthermore, the pile body 100 is made of pine wood, and the pile body 100 is preferably pine wood with a diameter of about 200 mm and a length of about 4 meters. The surface is coated with an asphalt anti-corrosion layer, and a drainage board is provided on the outside of the treated pine wood.
[0037] By improving the form of traditional pine piles and adding drainage channels 200, the foundation is strengthened while increasing the drainage and water-repellent function, discharging moisture from the original foundation soil, strengthening the bearing capacity of the foundation, and accelerating the realization of foundation solidification and improvement functions. While retaining the role of traditional pine piles in reinforcing the foundation, the role of drainage and consolidation of the soil is increased, and the efficiency of the pine pile method in treating soft foundations is improved. It can be widely used in the reinforcement of soft soil foundations of coastal roads and soft foundations of small hydraulic structures.
[0038] Example 2

[0040] The wire mesh covers the drain board to protect it, thereby preventing the deformation of the drain board and playing the role of primary water seepage and isolating silt and other substances. The geotextile covers the drain board to further block the silt and prevent the silt from infiltrating and clogging the drain board. The drain board, wire mesh and geotextile should exceed the end of the pile body by at least 300mm.
[0041] In this embodiment, the geotextile is preferably a long-fiber hot-rolled non-woven fabric.
[0042] The rest of the structure is the same as that of Example 1.

[0045] After the pile body 100 is embedded in the soft foundation, the drainage board, wire mesh, and geotextile extending beyond the pile body 100 are buried in the drainage sand cushion layer 500 to serve as a drainage channel 200 .
[0046] The rest of the structure is the same as that of Example 2.
