Description

Technical Field

[0001] This utility model relates to a prefabricated collection and drainage component, belonging to the field of drainage technology. Background Technology

[0002] Drainage boards are commonly used in engineering construction projects for the treatment of various soft and hard soil foundations. They are an environmentally friendly, economical, effective, reliable, and mature physical drainage and water-air separation technology.

[0003] Furthermore, Chinese Patent (Announcement No.: CN220468524U) discloses a three-dimensional composite drainage pad with water and air pipelines, which includes at least a drainage body one and a drainage body two; the drainage body one is partially or entirely a raised structure; the raised structure cooperates with the wall surface of the drainage body two to form a pipeline that can flow water and air; the drainage body two is fixedly connected to the drainage body one to form a three-dimensional composite drainage pad with water and air pipelines.

[0004] The above scheme sets up drainage body one and drainage body two with raised structures. The raised structures cooperate with the wall of drainage body two to form a pipeline that can carry water and air. However, the pipelines are set up independently, which means that when the three-dimensional composite drainage pad is actually applied, the water and gas in the soil cannot be gathered together and can only flow in the corresponding pipelines. Therefore, it is impossible to collect and drain water and vent air, which affects the drainage or drainage-air efficiency. This leads to a longer construction time for the soil foundation and is not conducive to its widespread use.

[0005] The information disclosed in this background section is only for understanding the background of the present invention, and therefore may include information that does not constitute prior art. Utility Model Content

[0006] To address the aforementioned problems, or one of them, the purpose of this utility model is to provide a prefabricated collection and drainage component, which includes plates, drainage channels, and filters. This allows water or water vapor in the soil or other drainage structures to permeate from the filters into the drainage channels. Under the constraint of the plates, the water in the soil or other drainage structures is collected together, facilitating collection and drainage and / or centralized venting. This effectively improves drainage or venting efficiency, thereby shortening the construction time for various soft and hard soil foundations and promoting its widespread use.

[0007] To address the aforementioned problems, or one of them, the second objective of this utility model is to provide a prefabricated collection and drainage component. The upper layer is a plastic sheet, forming a semi-enclosed suction space. The middle layer incorporates a plastic geogrid as a drainage channel, facilitating subsequent drainage. The lower layer uses fiber filter cloth to filter debris from the soil, effectively preventing blockage at the drainage pipe ports. This significantly improves suction efficiency, reduces resistance, and increases drainage flow, thereby enhancing the efficiency of vacuum preloading drainage consolidation, shortening the drainage time required for various soft and hard soil foundations, and ultimately reducing the overall project duration.

[0008] To achieve one of the above objectives, the first technical solution of this utility model is as follows:

[0009] A prefabricated water collection and drainage component includes a plate for limiting the direction of water and / or air flow, a drainage channel for draining and / or venting, and a filter element for filtering water or water vapor in the soil. The plate, drainage channel, and filter element are assembled together in sequence to form the prefabricated water collection and drainage component. The prefabricated water collection and drainage component allows water or water vapor in the soil to permeate from the filter element into the drainage channel, and under the limitation of the plate, it can collect and drain water or drain air.

[0010] Through continuous exploration and experimentation, this utility model incorporates plates, drainage channels, and filter elements. This allows water or water vapor in the soil or other filtration structures to permeate from the filter elements into the drainage channels. Under the constraint of the plates, the water and / or gas in the soil or other filtration structures are gathered together, facilitating drainage and / or centralized venting. This effectively improves drainage or venting efficiency, thereby shortening the construction time for various soft and hard soil foundations and promoting its widespread use.

This can improve the permeability of the filter elements, reduce the seepage resistance, and increase the seepage flow rate, making it easier for water and air to be discharged from various soil foundations. As a result, the water content in the soil can be continuously reduced, the degree of consolidation can be continuously improved, and the strength can be continuously improved.

Conversely, when an object is said to be "directly on" another object, there is no intervening object.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "or / and" as used herein includes any and all combinations of one or more of the associated listed items.

[0074] like Figures 1-4 As shown, the first specific embodiment of the prefabricated collection and drainage component of this utility model is as follows:

[0075] A prefabricated water collection and drainage component includes plates for changing the direction of water flow, drainage channels for diverting water, and filter elements for filtering water or water vapor from the soil. The plates, drainage channels, and filter elements are assembled sequentially to form the prefabricated water collection and drainage component. This component allows water or water vapor from the soil to permeate from the filter elements into the drainage channels, and, under the constraint of the plates, can collect and drain water or water vapor. The filter elements directly filter water and / or water vapor from the soil; or, the filter elements filter water and / or water vapor from the soil through a composite drainage structure.

[0076] In this embodiment: the plate is a plastic plate 1, which is encapsulated together with the filter element to form a semi-closed water-air chamber.

[0077] In this embodiment: the semi-enclosed water-containing air chamber is connected to a drain pipe 4, and the drain pipe 4 is equipped with a driving source, which is a vacuum pump.

[0078] The drainage pipe 4 is an inverted L-shaped structure, with one end extending outside the soil and a drive source installed at that end. The other end is fused together with an opening on the plastic plate 1 to form a negative pressure suction structure, thereby improving the negative pressure suction strength and suction efficiency. The drainage pipe 4 is a plastic drainage pipe with a circular cross-section.

[0079] In this embodiment, the drainage channel is one or more layers of plastic geogrid 2, which is assembled between the plates and filter elements to serve as a drainage channel. The plastic geogrid 2 includes several horizontally and vertically arranged plastic strips 21, which have a simple and practical structure and low manufacturing cost.

[0080] In this embodiment, the filter element is a high-strength permeable fiber filter cloth 3, which is laid in one or more layers. Its edge is fused and sealed with the edge of the plate, so that the fusion area at the connection between the two is large and the seal is firm and reliable.

[0081] The high-strength permeable fiber filter cloth 3 is made of polyester fiber, polypropylene fiber, nylon fiber, vinylon fiber, cotton, or glass fiber.

[0082] A second specific embodiment of the prefabricated collection and drainage component of this utility model:

[0083] A prefabricated drainage system includes plates, drainage channels, and filter elements;

[0084] The plate is a plastic plate 1; the drainage channel is one or more layers of plastic geogrid 2; the filter element is a fiber filter cloth 3;

[0085] Plastic sheet 1, plastic geogrid and fiber filter cloth 3 are stacked and fused together in sequence to form a semi-closed water and air chamber.

[0086] The semi-enclosed water-containing air chamber is connected to a drain pipe 4;

[0087] The drainage pipe 4 is an inverted L-shaped structure. One end of the pipe extends outside the soil and a drive source is installed at that end. The other end is fused together with the opening on the plastic plate 1 to form a negative pressure suction structure, thereby improving the negative pressure suction strength and suction efficiency, and thus quickly expelling water vapor from the soil to the ground, thereby compressing the soil, increasing the soil density, changing the compressive strength of the soil and reducing the amount of compression deformation.

[0088] In this embodiment: the thickness of the plastic sheet 1 is 1-5 mm and its width is 0.5-3 m, which is located in the upper layer; the plastic geogrid 2 is located in the middle layer as a drainage channel; the lower layer is the fiber filter cloth 3. The three materials are combined into a prefabricated drainage component by pressing strips and welding edges, so that the suction area of ​​the prefabricated drainage component can reach 1-4 square meters. The shape of the prefabricated drainage component is a circular structure, a square structure, a triangular structure, or an arc structure.

[0089] In this embodiment, the filter element, plastic plate 1, and plastic geogrid are pressed and fused together to form an integral structure, which makes the filter element less prone to cracking, the corners less prone to friction damage, and the plastic plate 1 and plastic geogrid less prone to breakage, thus ensuring the water flow performance of the drainage board.

[0090] Meanwhile, the integrated drainage structure avoids the tooth-like phenomenon caused by the shrinkage of the core board edge during the production process of traditional drainage boards, thus ensuring the water flow performance of the drainage board.

[0091] Furthermore, the 1.5m wide drainage board of this utility model can be produced in different widths using slitting technology. It can replace the horizontal drainage function of sand cushion layer, and at the same time, it also has the functions of geogrid reinforcement and geotextile reverse filtration. It can improve the water permeability of drainage board filter element, reduce seepage resistance, and increase seepage flow, so that water and air in various soft and hard soil foundations can be easily discharged. Therefore, the water content in the soil can be continuously reduced, the degree of consolidation can be continuously improved, and the strength can be continuously improved. In this way, the foundation settlement and uneven settlement can be gradually eliminated to meet the use requirements of land, marine and sewage environment engineering projects.

[0092] like Figures 5-6As shown, this is the third specific embodiment of the prefabricated collection and drainage component of this utility model:

[0093] A prefabricated drainage system is mainly composed of a plastic sheet 1, a plastic mesh sandwich panel, and a filter element stacked with pressure strips and fused edges.

[0094] The upper layer of the component is a 2mm thick plastic sheet 1, which provides a solid foundation for the entire component. The middle layer contains a plastic geogrid 2, which serves as a drainage channel to facilitate subsequent drainage work. The lower layer uses a high-strength permeable fiber filter cloth 3 to filter impurities in the soil, thereby effectively preventing the drainage pipe 4 from becoming clogged. This effectively improves the pumping efficiency, reduces resistance, and increases the drainage flow. The plastic geogrid consists of several horizontally and vertically arranged plastic strips, which are interlocked to form a grid drainage structure. Therefore, it can effectively improve the efficiency of vacuum preloading drainage consolidation, shorten the drainage time required for various soft and hard soil foundations, and thus shorten the construction period of the entire project.

[0095] In this embodiment, an opening is designed at the center of the upper plastic plate 1 for welding with the port of the plastic drain pipe, forming an integrated connection structure. This significantly expands the area of ​​the suction port of the drain pipe 4 to 1-2.25 square meters, effectively improving the negative pressure suction strength and achieving a qualitative leap in suction efficiency.

[0096] Meanwhile, to ensure a good seal, the interface between the flat layer of the plastic plate 1 and the filter element is also welded and sealed, making the seal more secure and reliable, and providing a solid guarantee for the entire drainage process.

[0097] like Figures 7-8 As shown, this is the fourth specific embodiment of the prefabricated collection and drainage component of this utility model:

[0098] A prefabricated water collection and drainage component includes plates for limiting the flow direction of water and / or air, drainage channels for diverting water and / or air, and filter elements for filtering water or water vapor from the soil. The plates, drainage channels, and filter elements are assembled sequentially to form the prefabricated water collection and drainage component. The prefabricated water collection and drainage component allows water or water vapor from the soil to permeate from the filter elements into the drainage channels, and, under the constraint of the plates, can collect and drain water or drain water vapor. The plates are provided with several strips 11, each strip 11 extending outward from the center of the plate to form a radial arrangement structure.

[0100] A prefabricated water collection and drainage component includes plates for limiting the flow direction of water and / or air, drainage channels for diverting drainage and / or air, and filter elements for filtering water or water vapor from the soil. Several columns 12 are arranged on one side of the plates adjacent to the filter elements, forming multiple drainage channels that are interconnected. This effectively increases the structural strength of the drainage component, provides good compressive strength, and allows for the formation of more drainage channels, thereby improving drainage and air efficiency.

[0101] like Figures 11-12 As shown, this is the sixth specific embodiment of the prefabricated collection and drainage component of this utility model:

[0102] A prefabricated water collection and drainage component includes a plate for changing the direction of water flow, a drainage channel for diverting water and drainage, and a filter element for filtering water or water vapor in the soil. The plate, drainage channel, and filter element are assembled together in sequence to form the prefabricated water collection and drainage component. The prefabricated water collection and drainage component allows water or water vapor in the soil to permeate from the filter element into the drainage channel, and can collect and drain water or drain water vapor under the limitation of the plate.

[0103] In this embodiment, the filter element filters water and / or air in the soil through a composite drainage structure; the composite drainage structure includes several vertical drainage plates 7, several horizontal drainage plates 5, and several longitudinal drainage plates 6;

[0104] The upper end of the vertical drainage board 7 is bent to form a bent section;

[0105] The bent portion is assembled with the transverse drainage plate 5 and / or the longitudinal drainage plate 6 to form a multi-directional interconnected drainage structure for collecting and draining water or draining air.

[0106] Several transverse drainage boards 5 and several longitudinal drainage boards 6 are laid in a transverse and longitudinal manner, or laid in a staggered and overlapping manner, or laid in an overlapping manner; the interval between transverse drainage boards 5 is 300 mm to 1500 mm.

[0107] The spacing between the longitudinal drainage boards 6 is 300 mm to 1500 mm;

[0108] There are multiple vertical drainage boards 7, with a spacing of 100 mm to 1000 mm.

[0109] Each horizontal drainage plate 5, vertical drainage plate 6, and vertical drainage plate 7 is provided with one or more drainage pipe fittings; the drainage pipe fittings include two layers of filter cloth and a plastic core with water flow channels. The edges of the two layers of filter cloth are fused together by heat fusion to form a receiving cavity covering the plastic core.

[0110] The drainage channel is connected to the drainage pipe 4 and the vacuum pump to perform vacuuming operations, forming a three-dimensional drainage system for the extraction and separation of water or drainage gas in the soil.

[0111] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it.
