Description

Technical Field

[0001] The invention relates to the technical field of slope protection equipment, in particular to a composite anti-seepage and drainage geocell. Background Art

[0002] The water and soil cells used for slope protection are also called three-dimensional slope protection grids. As a long-term slope protection layer, it has obvious soil fixing effect. Before the grass grows, it can protect the slope from wind and rain erosion. After the grass seeds are sown, the grass seeds can be firmly and evenly distributed on the slope to avoid being lost by wind and rain. It can avoid the impact of heavy rain and rainstorms, and can withstand the impact of high water levels and large flows, replacing concrete, mortar and rubble stone.

[0003] Since the geocell is composed of multiple sheets with row holes, traditional sheets are all integrated structures. In order to ensure the drainage effect of the geocell, row holes need to be opened on the sheet. The grid unit formed by the geocell will provide a limited wrapping effect on the soil part, preventing part of the soil from being lost due to water flow. The water that penetrates into the grid unit flows into the next grid unit through the row holes on the sheet, and so on, until the end of the entire geocell is discharged. This type of drainage method belongs to the connected linear drainage form. On rainy days, rainwater will penetrate into each grid unit of the geocell. Therefore, each grid unit will introduce water flowing into the side grid unit while achieving drainage. At the same time, it will be affected by the filling soil, which will inevitably cause the water flow rate to be slow and the fluidity to be poor. When some grid units are blocked, the water level in the grid unit will rise, affecting the soil on the surface of the slope protection, accelerating the loss rate of the soil, thereby directly affecting the protection effect of the geocell on the slope protection. The present invention provides a composite anti-seepage drainage geocell. Summary of the invention

[0004] The object of the present invention is to provide a composite anti-seepage drainage geocell to solve the problem in the above background technology that the sheet material used in the traditional geocell has a fixed structure, which limits the drainage method and affects the drainage effect.

[0005] To achieve the above object, the present invention provides the following technical solutions: A composite anti-seepage drainage geocell, comprising a plurality of sheets for forming geocells, and the interior of the sheets is a semi-closed hollow structure, the sheets are provided with welding areas for splicing the plurality of sheets to form grid chamber units, a filter screen is arranged on the top of the sheets, and a top seat is also provided, which matches the shape of the sheets and is a semi-closed hollow structure, the top seat is fixed to the top of the sheets, a plurality of partitions for dividing the top seat are arranged in the top seat, the plurality of partitions divide the top seat into a plurality of filling cavities of uniform size, the bottom surfaces of the plurality of filling cavities are a mesh structure, and a filter cloth is arranged between the bottom surface of the filling cavity and the filter screen ; A flow channel is arranged inside the sheet material, and is used for uniformly draining the water that penetrates into the sheet material. The flow channel is formed by splicing two groups of strip sheets extending downward at a fixed angle along the center position of the inner walls on both sides of the sheet material. A plurality of connecting frames for providing stable support for the sheet material are arranged on the top side of the flow channel, and connecting gaps are arranged between the plurality of connecting frames; row holes are opened on both sides of the welding area, the row holes are distributed in a matrix, and the row holes are in a tubular structure as a whole. The tube body portion of the row holes is connected through the connecting gaps between the plurality of connecting frames, and through holes for diverting the water flowing into the row holes are distributed on the tube body portion of the row holes.

[0006] As a preferred embodiment of the present invention, the flow channel is an overall "V"-shaped structure, and a plurality of groups of conical heads for installing the sheet are distributed at the bottom of the flow channel. The conical heads extend outside the bottom of the sheet and are provided with barbs.

[0007] As a preferred embodiment of the present invention, an eaves panel extending in an arc shape toward the inner side of the grid chamber unit is provided at the connection between the top seat and the sheet material. The eaves panel is arranged between multiple welding areas on the sheet material to provide limited wrapping for the filler in the grid chamber unit.

[0008] As a preferred embodiment of the present invention, the filter cloth is provided with a plurality of strip-shaped slots distributed at intervals to provide good flowability for water infiltrating the filling cavity, and a wire mesh with a wavy structure is provided in the strip-shaped slots.

[0009] As a preferred embodiment of the present invention, the connection gaps between the multiple groups of the connection frames are larger than the diameter of the row holes, and the connection frames are cross-shaped frames.

[0010] As a preferred embodiment of the present invention, the plurality of groups of through holes are arranged in a circular pattern according to the hole arrangement tube body portion, and the plurality of groups of through holes correspond to the positions of the flow channels.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. The sheet material used in the local geocell adopts a semi-closed hollow structure with a flow channel inside, which has the effect of independent drainage. Rainwater passes through the top seat, and is filtered through the mesh body and filter cloth at the bottom of the base in turn, and then flows into the flow channel inside the sheet material for drainage. The independent drainage structure of the sheet material has changed the drainage method of the traditional geocell, so that the geocell has both sheet drainage and grid room unit drainage, which effectively enhances the overall drainage efficiency of the geocell.

[0012] 2. The drainage holes on the local geocell sheet adopt a tubular structure and are connected to the inside of the sheet. When water flows through the drainage holes between different grid chamber units, it can be diverted through the through holes set on the tube body, so that the diverted water enters the flow channel and is discharged together with the water infiltrated into the sheet itself. Therefore, through the above method, the independent drainage between each grid chamber unit is effectively realized, and the load on the entire geocell caused by the sequential connection drainage between the grid chamber units is reduced. At the same time, it also avoids the obstruction of soil during the water flow between each grid chamber unit, resulting in slow drainage speed and low efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

Implementation

[0014] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0015] See also Figure 1-7 , the present invention provides a technical solution: A composite anti-seepage drainage geocell, comprising a plurality of sheets 1 for forming geocells, wherein the interior of the sheets 1 is a semi-closed hollow structure, a welding area 2 for splicing the plurality of sheets 1 to form a grid chamber unit is distributed on the sheets 1, and a filter screen 11 is arranged on the top of the sheets 1; The top seat 3 is consistent with the shape of the sheet 1 and is a semi-closed hollow structure. The top seat 3 is fixed to the top of the sheet 1. A plurality of partitions 7 for dividing the top seat 3 are arranged inside the top seat 3. The plurality of partitions 7 divide the top seat 3 into a plurality of filling cavities of uniform size. The bottom surfaces of the plurality of filling cavities are in a mesh structure. A filter cloth 10 is arranged between the bottom surface of the filling cavity and the filter screen 11. Further explained, the top seat 3 has the same shape as the sheet 1 forming the geocell, and is connected end to end according to the shape of the sheet 1. When the rainwater scours the slope protection, after the rainwater enters the filling cavity, the top seat 3 penetrates the rainwater and uses the flow channel 4 inside the sheet 1 for drainage. On the one hand, the self-drainage of the sheet 1 is realized, and on the other hand, the load generated by the unified drainage of the grid room unit is reduced; The flow channel 4 is arranged inside the sheet 1 and is used to uniformly drain the water that penetrates into the sheet 1. The flow channel 4 is formed by splicing two groups of strip-shaped sheets extending downward at a fixed angle along the center of the inner walls on both sides of the sheet 1. A plurality of groups of connecting frames 6 are arranged on the top side of the flow channel 4 to provide stable support for the sheet 1. A connecting gap is provided between the plurality of groups of connecting frames 6. Further explained, the flow channel 4 is mainly used to uniformly drain the infiltrated water, that is, the sheet 1 provides an unobstructed circulation space for the infiltrated water and the water diverted by the grid chamber unit, avoiding the situation where the drainage rate is slow and the drainage effect is poor due to the obstruction of the soil; The row holes 5 are provided on both sides of the welding area 2, the row holes 5 are distributed in a matrix, and the row holes 5 are in a tubular structure as a whole. The connecting gaps between the tubular body of the row holes 5 and the multiple groups of connecting frames 6 are connected in a through-type manner, and the tubular body of the row holes 5 is provided with through holes 13 for diverting the water flowing into the row holes 5; Further explained, the tubular drainage holes 5 divide the water flowing between each grid chamber unit and discharge it independently through the flow channel 4, so as to achieve the effect of independent drainage of the grid chamber unit. Through the cooperation between the tubular drainage holes 5 and the flow channel 4, the load generated when the geocell is drained can be greatly reduced, so as to achieve the effect of rapid drainage. In order to realize the installation of the sheet 1, refer to Figure 3 The flow channel 4 is in a "V"-shaped structure as a whole. A plurality of groups of conical heads 9 for installing the sheet 1 are distributed at the bottom of the flow channel 4. The conical heads 9 extend outside the bottom of the sheet 1 and are provided with barbs. Specifically, by embedding multiple groups of cone heads 9 with barbs inside the slope protection, the stability and firmness of the sheet 1 installed on the slope protection can be enhanced; In order to provide overall wrapping for the soil in the grid chamber unit, the loss of soil can be prevented to the greatest extent when affected by water flow. Figure 3 As shown, the connection between the top seat 3 and the sheet 1 is provided with an eaves plate 8 extending in an arc shape toward the inner side of the grid room unit, and the eaves plate 8 is arranged between a plurality of welding areas 2 on the sheet 1, and is used to provide limited wrapping for the filler in the grid room unit; Specifically, by adding the eaves 8, the top edge of the grid room unit forms a wrapping area for protecting the soil, achieving the effect of providing a local wrapping effect on the soil, and preventing the soil from being affected by the water flow and flowing along the edge of the grid room unit; In order to improve the water infiltration of the top seat 3 and provide a good circulation effect, Figure 5 As shown, the filter cloth 10 is provided with a plurality of strip-shaped slots 12 distributed at intervals, which are used to provide good flowability for water infiltrating into the filling cavity, and a wire mesh with a wavy structure is provided in the strip-shaped slots 12; Specifically, since the filter cloth 10 is made of cloth, although it can provide a good filtering effect, the cloth is made of fiber material, which will hinder the flow of water, resulting in a slow flow rate. Therefore, in order to ensure the flowability and filtering effect of the filter cloth 10, a strip-shaped slot 12 with a wire mesh is provided on the filter cloth 10 to improve the flowability of water while ensuring the filtering effect; In order to ensure the overall flow of the matrix-arranged tubular holes 5, Figure 6 As shown, the connection gaps between the multiple groups of connecting frames 6 are larger than the apertures of the row holes 5, and the connecting frames 6 are cross-shaped frames; At the same time, the plurality of through holes 13 are arranged in a circular pattern according to the tube body portion of the hole arrangement 5, and the plurality of through holes 13 correspond to the positions of the flow channel 4; Specifically, the gap between the connecting frames 6 needs to be larger than the row holes 5, so that a reserved flow gap is formed between the two sides of the row holes 5 and the connecting frames 6, so that the through holes 13 on the pipe body of the row holes 5 arranged longitudinally do not affect each other when draining water; If necessary, Figure 7 As shown, the head of each sheet 1 is a closed structure to prevent mud from entering the interior of the sheet 1, and the tail is an open structure to achieve water discharge; In summary, multiple sheets 1 are horizontally laid flat on the slope of the slope protection. Under the premise of ensuring the correspondence of the welding area 2, multiple sheets 1 are inserted into the slope protection through the conical head 9 in turn, and multiple independent sheets 1 are welded as a whole through the welding area 2. Soil is filled in the grid chamber unit formed by each sheet 1, and finally the whole is buried with soil. On rainy days, rainwater penetrates into the grid chamber unit and sheet 1 of the geocell through the soil. The rainwater will enter the filling cavity through the soil, and will be filtered twice through the mesh structure and filter cloth 10 at the bottom of the filling cavity. Then, it will enter the interior of the sheet 1 and flow into the flow channel 4. It will be introduced to the end of the sheet 1 through the flow channel 4 for external discharge. At the same time, rainwater will also penetrate into each grid chamber unit and circulate through the discharge hole 5. When the water flow enters the discharge hole 5, it will be diverted through the multiple through holes 13 on the pipe body part, and the diverted water will be introduced into the flow channel 4 inside the sheet 1, and will flow into the end of the sheet 1 together with the water flowing into the filling cavity for external discharge.
