Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of geotechnical honeycomb cells, in particular to a geotechnical honeycomb cell which is integrally formed by plastic extrusion and is provided with a drainage channel in the middle. Background Art
[0002] Geocomb cells are an engineering material used for soil conservation and protection, and their structural shape is similar to a honeycomb. One-piece geocomb cells are usually formed by a plastic extruder, which melts the polymer and then extrudes the mesh and stretches it into a one-step molding. They are widely used in projects such as roads, dams, riverbanks, reservoirs, rivers, and hillsides.
[0003] Traditional geotextile honeycomb cells generally have drainage holes on the side walls of each honeycomb cell. During heavy rains, the soil in the honeycomb cells is easily washed away by rainwater or other factors and clogged in the drainage holes, rendering the drainage holes ineffective. This results in the inability to drain excess water in the honeycomb cells, which in turn increases the load on the honeycomb cells and is prone to landslides.
[0004] Therefore, a geocomb cell with a drainage channel in the middle formed by plastic extrusion is needed to solve the above problems. Utility Model Content
[0005] 1. Technical issues to be solved
[0006] The utility model provides a geotechnical honeycomb cell with a drainage channel arranged in the middle of a plastic extrusion integrally formed body, aiming to solve the problem raised in the background technology that during heavy rain, the soil in the honeycomb cell is easily washed away by rainwater or blocked in the drainage hole by other factors, making the drainage hole ineffective, thereby causing the excess water in the honeycomb cell to be unable to be discharged, thereby increasing the load on the honeycomb cell and easily causing landslides.
[0007] (II) Technical solution
[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a geotechnical honeycomb cell with a drainage channel arranged in the middle of a plastic extrusion integrally formed structure, comprising a plurality of honeycomb cells for filling with grass seeds and soil, wherein the plurality of honeycomb cells are integrally formed, and a drainage structure is arranged between two adjacent honeycomb cells; the design of plastic extrusion integrally formed structure can realize one-time forming of a plurality of honeycomb cells, eliminating the step of building the honeycomb cells one by one in traditional construction, thereby improving construction efficiency; at the same time, the setting of the drainage structure can promote the smooth discharge of water, avoid water retention in the honeycomb cells, thereby reducing the adverse effects on soil and grass seeds.
[0009] In order to reduce the risk of landslide, unlike the existing geotextile honeycomb cells, the drainage structure includes vertical drainage grooves for the longitudinal flow of slope water; the design of the vertical drainage grooves can quickly drain the excess water in the soil of each honeycomb cell, reducing the directional fracture caused by the dead weight of the soil. At the same time, the vertical drainage grooves can also reduce the connection strength requirements between the honeycomb cell sheets, reducing the risk of fracture.
[0010] In order to reduce the impact of water flow on each honeycomb cell, a slow-flow structure for water flow buffering is provided in the vertical drainage channel. The design of the slow-flow structure can reduce the impact force of the water flow and make the water flow more stably through the vertical drainage channel, thereby reducing the scouring damage caused by the water flow to the slope protection.
[0011] Preferably, in order to reduce transportation costs, an opening and closing accordion structure design is adopted between the multiple honeycomb cells; the opening and closing accordion structure can allow the geotextile honeycomb cells to be folded or compressed before transportation, reducing the volume of a single honeycomb cell, thereby increasing the loading capacity of each transport vehicle and reducing the number and cost of transportation.
[0012] Preferably, in order to improve the drainage effect of the vertical drainage groove, the slow-flow structure includes a baffle fixedly connected to the vertical drainage groove and a through hole opened on the baffle; when the water flows through the baffle and the through hole, the water flow will be dispersed and diverted, thereby reducing the impact force of the water flow on the soil in each honeycomb cell; at the same time, it can also avoid the blockage of the vertical drainage groove.
[0013] Preferably, in order to allow the water to flow through the baffle more smoothly, a plurality of through holes are provided; the design of multiple through holes can evenly disperse the water flow into each through hole, so that the water flow can pass through the baffle more smoothly, reducing the impact and damage caused by the water flow to the drainage structure.
[0014] Preferably, in order to ensure the drainage efficiency, the through hole is trumpet-shaped; since the through hole is trumpet-shaped, its cross-sectional area gradually expands as the fluid passes through, so that the water flow can pass through the slow-flow structure more easily, thereby improving the drainage efficiency.
[0015] Preferably, in order to ensure the normal operation of drainage, the opening diameter of the through hole close to one end of the water inlet of the vertical drainage groove is not less than the opening diameter of the other end of the through hole; the opening diameter of the through hole close to one end of the water inlet of the vertical drainage groove is not less than the other end of the through hole, which can ensure that the excess water flow in each honeycomb cell can flow smoothly from the vertical drainage groove.
[0016] (III) Beneficial effects
[0017] The geotextile honeycomb cell can reduce the soil load in each honeycomb cell by setting vertical drainage grooves, reduce the risk of surface breakage, and thus achieve the effect of reducing the risk of landslides. At the same time, the vertical drainage grooves can also reduce the connection strength requirements between the honeycomb cell sheets and reduce the risk of fracture.
[0018] The geotextile honeycomb cell adopts an open-and-close accordion structure, which can compress the volume of a single honeycomb cell during transportation, reducing the number of transportation times and costs;
[0019] The geotextile honeycomb cell can reduce the impact of water flow by setting a slow flow structure, allowing the water flow to flow more stably through the vertical drainage channel, thereby reducing the scouring damage caused by the water flow to the slope protection.

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0028] The utility model provides a geotechnical honeycomb cell with a drainage channel arranged in the middle of a plastic extrusion integrally formed body. Figure 1-Figure 3As shown, the geotextile honeycomb cell includes a plurality of honeycomb cells 1 for filling with grass seeds and soil, the plurality of honeycomb cells 1 are integrally formed, a drainage structure 2 is arranged between two adjacent honeycomb cells 1; the drainage structure 2 includes a vertical drainage groove 21 for the longitudinal flow of slope water; a slow flow structure 3 for buffering the flow of water is arranged in the vertical drainage groove 21.
[0029] During use, when the geocomb cell is applied to the slope, first ensure that each honeycomb cell 1 is intact, and then fill the prepared grass seeds and soil into each corresponding honeycomb cell 1. After the grass seeds and soil are filled, the geocomb cell is further fixed and ensure that it is stably fixed on the slope, and then appropriate maintenance is carried out, including regular watering, fertilizing, etc., to promote the growth and development of the grass seeds. However, during the use of the geocomb cell, if there is excess water flow in the soil of each honeycomb cell 1, the water flow will be directly and quickly discharged from the vertical drainage groove 21, thereby reducing the load on the soil in each honeycomb cell 1 and reducing the risk of surface damage. In addition, when the water flows into the vertical drainage groove 21, it will also be under the buffering effect of the slow flow structure 3, which can reduce the impact on the soil in each honeycomb cell 1, reduce damage to the slope, and improve the protection of the slope.
[0030] Specifically, the flow-slowing structure 3 includes a baffle 31 fixedly connected to the vertical drainage groove 21 and a through hole 32 opened on the baffle 31; a plurality of through holes 32 are provided; when water flows through the vertical drainage groove 21, the water flow will first be blocked by the baffle 31 and the through hole 32 to reduce the impact force of the water flow. At the same time, the design of multiple through holes 32 can further disperse the water flow with reduced speed, thereby further reducing the impact and helping to improve the drainage effect. In addition, through the blocking of the baffle 31, the vertical drainage groove 21 can be effectively avoided from being blocked.
[0031] Among them, in order to ensure that the water flows through the baffle 31 more smoothly, the through hole 32 is trumpet-shaped; the opening diameter of the through hole 32 at one end close to the water inlet of the vertical drainage groove 21 is not less than the opening diameter of the other end of the through hole 32; because the through hole 32 is trumpet-shaped and the opening at one end close to the water inlet of the vertical drainage groove 21 is larger, when the water flows into the through hole 32, it will gradually expand, thereby producing a gradual expansion process, and this expansion effect helps to reduce the impact force of the water flow on the baffle 31, allowing the water flow to flow more smoothly.
[0032] Furthermore, an opening and closing accordion structure design is adopted between the multiple honeycomb cells 1; when the geotextile honeycomb cells are transported, since the opening and closing accordion structure is adopted between the multiple honeycomb cells 1, the multiple honeycomb cells 1 can be folded or compressed to reduce the volume of a single honeycomb cell 1, thereby increasing the loading capacity of each transport vehicle and reducing the number of transportations and costs.
[0033] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
