Description

Technical Field

[0001] This invention relates to a drainage board for treating soft soil foundations of buildings, specifically within the technical field of building foundations and foundation structures for large public facilities. Background Technology

[0002] Large-scale infrastructure projects and public facilities often employ drainage settlement techniques, particularly when treating soft soil foundations, to achieve balanced and stable foundation settlement. This involves inserting drainage boards into the ground to drain moisture from the soil, thus achieving uniform settlement and soil consolidation. With the continuous development of the construction industry and technological advancements, the technical requirements for drainage boards used in soft soil foundation treatment are becoming increasingly stringent. This is because drainage boards are one of the most effective measures for treating soft soil foundations, directly impacting the stability of the building's foundation structure. In existing technologies, drainage boards for soft soil foundation treatment primarily consist of a plastic core board and an outer permeable filter membrane. For example, Chinese Patent Publication No. CN205875126U discloses a drainage board for soft foundation treatment. It is a plastic core board made of polypropylene, consisting of several groups of adjacent trapezoidal tooth-shaped protrusions. The outer permeable filter membrane is made of chemically synthesized fiber non-woven fabric. Due to its structural limitations, its structural design is unreasonable. Because it uses chemically synthesized raw materials, harmful chemicals cannot be avoided from seeping in during the production process. Moreover, some of them use recycled raw materials, which means that the drainage board made of recycled raw materials may have harmful and toxic substances accumulating in the foundation soil, posing a risk of continuous and irreversible pollution to groundwater and soil. In addition, the existing drainage board has a small cross-sectional structure of drainage channels in the core board, which is easily blocked by fine soil sediment that permeates through the permeable filter membrane, resulting in slow drainage rate and affecting the construction period. The fine soil sedimentation blocking some drainage channels causes uneven drainage and causes settlement and instability problems in the treated soft foundation. In view of this, in order to adapt to the actual needs of the continuous development and technological progress of large-scale infrastructure projects and public facilities construction, it is necessary to further improve and develop a new type of drainage board and its manufacturing device for soft soil foundation treatment of buildings. Summary of the Invention

[0003] To overcome the shortcomings of existing technologies and address the problem of unreasonable structural design and pollution of groundwater and soil caused by existing drainage boards used in soft soil foundation treatment of buildings, the present invention aims to provide a novel and practical product and its manufacturing device. This product uses plant fibers as raw materials, and the resulting drainage board is biodegradable after application, contains no harmful chemical substances that pollute groundwater and soil, has a large cross-sectional structure for the core board drainage channels, provides balanced consolidation and stability for treated soft soil foundations, and is easy to use.

[0015] The aforementioned integrated biodegradable drainage board manufacturing device combining core board and permeable filter membrane, wherein the raw material sorting and conveying mechanism is either an extendable inclined raw material conveyor belt or a mobile conveyor belt.

[0018] When using this invention, the drainage board manufacturing device of this invention is installed in the production workshop or other applicable places according to the design requirements and actual needs, the power supply is turned on, and the raw materials are prepared according to the product to be manufactured.

[0019] (1) Selection of raw materials for core board: The raw materials for core board include corn stalks, wheat straw, bean stalks, sorghum stalks, rice stalks, cotton stalks, cotton ginning mill waste cotton, peanut shells, tomato stalks, chili stalks, eggplant stalks, sunflower seed heads, sunflower stalks, lint scraps, reed stalks, and fast-growing poplar pulping scraps, etc., or 6-16 of them can be used;

[0020] For example, the weight ratio of raw materials is as follows: 15 parts corn stalks: 20 parts wheat straw: 20 parts bean stalks: 20 parts sorghum stalks: 10 parts rice stalks: 15 parts cotton stalks: 10 parts peanut shells: 10 parts tomato stalks: 10 parts chili stalks: 10 parts eggplant stalks: 11 parts sunflower seed heads: 10 parts sunflower stalks: 25 parts cotton ginning mill waste cotton: 10 parts lint scraps: 15 parts reed waste straw: 10 parts fast-growing poplar paper pulping scraps; or other applicable ratios according to product quality requirements.

[0021] (2). Core board raw material pretreatment system: The weighed core board raw materials are put into the raw material pretreatment machine for pretreatment. After pretreatment, they are conveyed to the wire rolling machine through the raw material screw conveyor for wire rolling and then conveyed to the raw material mixing tank. While stirring in the raw material mixing tank, liquid plant adhesive is sprayed into the raw material mixing tank through the adhesive spraying mechanism. After stirring evenly, the material is discharged through the valve and conveyed to the core board raw material storage box through the raw material classification conveyor.

[0022] (3) Selection of raw materials for permeable filter membranes: The raw materials for permeable filter membranes include, but are limited to, recycled waste hemp, waste hemp from hemp mills, waste hemp from the roots of hemp stalks in hemp fields, cotton from cotton mills, flax, jute, ramie, sisal, and 2-8 other fiber raw materials with better toughness and longer fibers than the core board raw materials.

[0023] Preferred weight ratios include: 30 parts recycled hemp waste; 25 parts waste hemp from hemp mills; 20 parts waste hemp from hemp stalk roots in hemp fields; 20 parts cotton from cotton mills; 15 parts jute; 10 parts ramie; 10 parts sisal; and 10 parts flax; or other suitable ratios based on product quality requirements.

[0024] (4). Pretreatment process of raw materials for permeable filter membrane: The raw materials for the production of permeable filter membrane are weighed and put into the raw material pretreatment machine for pretreatment. After pretreatment, they are conveyed to the filament rolling machine by the raw material screw conveyor for filament rolling. After filament rolling, they are automatically conveyed to the raw material mixing tank. While stirring is started, liquid plant adhesive is sprayed into the raw material mixing tank by the adhesive spraying mechanism. After stirring evenly, the discharge valve is opened and the raw material is conveyed to the permeable filter membrane raw material storage box by the raw material classification and conveying mechanism.

[0025] (5) Water-permeable filter membrane raw material spreading and conveying process: This raw material spreading mechanism is installed at the lower part of the discharge port of the water-permeable filter membrane raw material storage box. The rotation speed of the water-permeable filter membrane raw material spreader is controlled by frequency conversion speed regulation to achieve the purpose of controlling the spreading raw material metering. The spreading thickness of the water-permeable filter membrane raw material is preferably 3-5mm. When the water-permeable filter membrane raw material spreader is started, the tenon and mortise forming motor reducer is started to make the raw material conveyor belt rotate and transport the raw material to the pre-compression forming process.

[0026] ⑹. Core board raw material spreading and conveying process: The core board raw material spreading device is installed at the lower part of the discharge port of the core board raw material storage box. The rotation speed of the core board raw material spreading device is controlled by frequency conversion speed regulation to achieve the purpose of controlling the spreading raw material metering. The core board raw material guide rollers installed below the raw material spreading device achieve different thicknesses of the core board raw material strips. According to the tensile strength requirements of the product, hemp rope or cotton rope with a diameter of 1.5-4mm is guided to the pre-compression forming roller. At the same time as starting the core board raw material and water permeable filter membrane spreader, the tenon and mortise forming motor reducer is started to make the raw material conveyor belt rotate, and the raw material is conveyed to the pre-compression forming system.

[0027] (7). Core board and permeable filter membrane pre-pressing process: The pre-pressing forming rollers take the raw material conveyed by the raw material conveyor belt and adjust the gap of the pre-pressing forming rollers by adjusting the pressure of the cylinder of the upper pre-pressing forming roller. After the raw material is rolled into a sheet, it is pushed into the tenon forming rollers. The upper tenon forming roller is a flat roller and the lower tenon forming roller has a raised groove-shaped roller surface. The lower tenon forming roller is a flat roller and the upper tenon forming roller has a raised groove-shaped roller surface. The gap of the pre-pressing forming rollers is adjusted by adjusting the pressure of the cylinder of the upper tenon forming roller. After the surface of the pre-pressed sheet reaches the tenon structure with longitudinal raised grooves, it is transported to the product shaping sheet composite process.

[0028] (8) In the product shaping sheet composite process, the core board and water-permeable filter membrane pre-pressed sheet from the above process are conveyed to the tenon and mortise composite pressure roller. The tenon and mortise composite lower pressure roller is equipped with a motor reducer, and the tenon and mortise composite upper pressure roller is equipped with a pressure cylinder to adjust the gap between the two tenon and mortise composite pressure rollers. The tenon and mortise shaped sheet conveyed by the lower tenon and mortise forming roller has the tenon and mortise protrusion and groove face upward, and the tenon and mortise shaped sheet conveyed by the upper tenon and mortise forming roller has the tenon and mortise protrusion and groove face downward. By radially adjusting the two layers of tenon and mortise shaped sheets, the tenon and mortise protrusion and groove faces of the upper and lower layers of tenon and mortise shaped sheets are aligned with each other. Then, the cylinder applies pressure to the tenon and mortise composite upper roller to complete the inlay and composite of the upper and lower layers of tenon and mortise shaped sheets into a single shaped sheet, which is then conveyed to the next process.

[0029] (9) Product drying and slitting into roll system process: After the shaped sheet material of the inlaid composite is pushed to the finished sheet material conveying pressure roller of this process, it is pressed into the drying oven by the pressure roller and then dried. After that, it is slitting into finished roll material with the following specifications: width 100mm, thickness 6-7mm, drainage channel width 3-4mm, and depth 2-3mm. The width of the production line is a multiple of 100mm. After the product passes the inspection, it is wound into a disc shape by the winding type winding shaft to become the core board and water permeable filter membrane tenon and tenon inlaid composite integrated biodegradable drainage board product of this invention.

[0030] The drainage board product of this invention can be used in the treatment of soft soil foundations in the same way as the existing drainage board construction process, which can be carried out by inserting it into the ground with special equipment.

[0031] Because this invention adopts the above-mentioned technical solution, it utilizes various plant fibers of different materials as raw materials, especially employing a composite process of double-core board tenon and mortise inlay and single-layer core board double-sided permeable filter membrane material, as well as a core board reinforcing rib installer to install the core board reinforcing ribs. The number of reinforcing ribs is determined according to the quality requirements of the drainage board to increase tensile strength. It can be applied to a wider range of different engineering quality standards, enabling the drainage board to degrade naturally and increasing the drainage channel space for smoother drainage. It effectively solves the problem of unreasonable structural design of existing drainage boards used for soft soil foundation treatment of buildings, which causes chemical pollution to groundwater and soil. Actual operation tests have shown that the product and its manufacturing equipment have novel and practical structures. They use plant fibers of different materials as raw materials, and the drainage board can be naturally degraded after application. The cross-sectional structure of the drainage channel in the core board is enlarged. Due to the use of high-density, high-water-filtration hemp fiber permeable filter membrane, it can effectively prevent soil from passing through the permeable filter membrane and clogging the drainage channel in actual application. It also has the advantages of balancing and consolidating the settlement of the treated soft foundation, wide applicability, and convenient use. It is suitable for industrial manufacturing of drainage boards for soft soil foundation treatment of large buildings and large public facilities.
