Description

Technical Field

[0001] The utility model relates to the technical field of geocomposite drainage nets, in particular to a geocomposite drainage net with geotextile embedded therein. Background Art

[0002] Geocomposite drainage net, also known as three-dimensional geotextile drainage net, tunnel drainage waterproof board, drainage reflector, is composed of a three-dimensional plastic net with permeable geotextile bonded on both sides. It can replace traditional sand and gravel layers and is mainly used for drainage of landfills, roadbeds and tunnel walls.

[0003] Upon investigation, a Chinese utility model patent discloses a geocomposite drainage net (publication number: CN217517632U), which includes a first composite drainage net and a second composite drainage net, and the second composite drainage net is arranged on the right side of the first composite drainage net.

[0004] Although the above patent connects the first composite drainage net and the second composite drainage net by means of a connecting box and a connecting hole in combination with a connecting plate, thus solving the problem that the existing geocomposite drainage nets cannot be well connected to each other during use, in daily use, due to the soft texture of the landfill material on the upper part of the composite drainage net, the geotextile is embedded in the mesh core structure, causing the non-woven fabric to enter the drainage net core and cause blockage, making the drainage channel unsmooth.

[0005] Therefore, the utility model provides a geocomposite drainage net with geotextile embedded therein to solve the above problems. Utility Model Content

[0006] 1. Technical issues to be solved

[0007] The utility model provides a geocomposite drainage net that prevents geotextile embedding, aiming to solve the problem in the background technology that the upper landfill material of the existing composite drainage net is relatively soft, resulting in the embedding of geotextile in the net core structure, causing non-woven fabric to enter the drainage net core and cause clogging, resulting in obstruction of the drainage channel.

[0008] (II) Technical solution

[0009] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a geocomposite drainage net with geotextile embedded therein, the composite drainage net comprising a supporting mechanism arranged in a drainage channel and a non-woven fabric arranged on the supporting mechanism.

[0010] The supporting mechanism includes a supporting plate placed in the drainage channel and a sawtooth block fixedly mounted on the supporting plate and in contact with the non-woven fabric. There are multiple sawtooth blocks, and at least four sawtooth blocks are provided with a limiting mechanism for limiting the position of the non-woven fabric, so that the non-woven fabric is firmly mounted on the sawtooth block and the non-woven fabric is separated from the supporting plate.

[0011] As a preferred technical solution of the present application, the supporting mechanism also includes a protrusion fixedly mounted on the sawtooth block and in contact with the non-woven fabric, thereby increasing the friction between the sawtooth block and the non-woven fabric.

[0012] As a preferred technical solution of the present application, a plurality of sawtooth blocks are vertically arranged on the support plate to increase the load-bearing capacity of the entire support mechanism.

[0013] As a preferred technical solution of the present application, the limiting mechanism includes a fixed rod fixedly mounted on the sawtooth block and passing through the non-woven fabric, a first magnetic block sleeved on the fixed rod, a second magnetic block slidably mounted on the fixed rod, and a receiving groove opened on the sawtooth block for placing the first magnetic block, so that the non-woven fabric is not easily displaced during use.

[0014] As a preferred technical solution of the present application, the non-woven fabric has a glass fiber grid in the middle and polymer filaments on both sides, which improves the strength of the non-woven fabric when in use.

[0015] As a preferred technical solution of the present application, a plurality of spunbonded thermally bonded filament glass fibers are fixedly connected inside the non-woven fabric to improve the load-bearing capacity and tensile strength of the non-woven fabric.

[0016] (III) Beneficial effects

[0017] The utility model is simple and easy to use. Through the arrangement of the support plate and the sawtooth block, the support plate supports the non-woven fabric as a whole through the sawtooth block. After the non-woven fabric is installed, the non-woven fabric is limited by the limiting mechanism, thereby reducing the embedding of the non-woven fabric. The support plate makes the drainage net as a whole more stable and firm and will not be easily compressed to cause blockage, thus avoiding the situation where the drainage net is easy to collapse and is more stable.

[0026] 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.

[0027] The utility model provides a geocomposite drainage net with geotextile embedded therein, such as Figure 1 , Figure 2 and Figure 3 As shown, the composite drainage net includes a support mechanism 2 arranged in a drainage channel and a non-woven fabric 1 arranged on the support mechanism 2 .

[0028] The support mechanism 2 includes a support plate 23 placed in the drainage channel and a sawtooth block 21 fixedly mounted on the support plate 23 and in contact with the nonwoven fabric 1. There are multiple sawtooth blocks 21, and at least four sawtooth blocks 21 are provided with a limiting mechanism 3 for limiting the position of the nonwoven fabric 1.

[0029] When it is necessary to place the geocomposite drainage net in the drainage channel, first take the support plate 23 and place it in the drainage channel, and place the serrated block 21 on the support plate 23 toward the direction of the liquid source, and then take the non-woven fabric 1 and install it on the serrated block 21. The bonding method of the serrated block 21 and the non-woven fabric 1 can be based on actual use requirements, using other methods such as thermal bonding or hot melt adhesive bonding, which will not be elaborated here. When the composite drainage net filters sewage, the sewage is filtered by the non-woven fabric 1 and penetrates the support plate 23 to complete the filtration of the sewage.

[0030] Furthermore, in order to increase the friction between the sawtooth block 21 and the nonwoven fabric 1, as Figure 3 and Figure 4 As shown, the supporting mechanism 2 further includes a protrusion 22 fixedly mounted on the sawtooth block 21 and in contact with the non-woven fabric 1 .

[0031] When the nonwoven fabric 1 is installed on the sawtooth block 21 , the protrusion 22 contacts the nonwoven fabric 1 , increasing the friction between the nonwoven fabric 1 and the sawtooth block 21 , so that the nonwoven fabric 1 is not easily deviated during installation and use.

[0032] In order to increase the bearing capacity of the entire supporting mechanism 2, as Figure 4As shown, a plurality of sawtooth blocks 21 are vertically arranged on the support plate 23 .

[0033] The vertical arrangement of the sawtooth blocks 21 can evenly distribute the load on the support plate 23 to the plurality of sawtooth blocks 21 , thereby extending the service life of the composite drainage net.

[0034] It should be noted that in order to prevent the nonwoven fabric 1 from being easily deflected during use, Figure 4 As shown, the limiting mechanism 3 includes a fixing rod 31 fixedly mounted on the sawtooth block 21 and passing through the non-woven fabric 1, a first magnetic block 32 sleeved on the fixing rod 31, a second magnetic block 33 slidably mounted on the fixing rod 31, and a receiving groove 34 opened on the sawtooth block 21 for placing the first magnetic block 32.

[0035] The first magnetic block 32 and the second magnetic block 33 attract each other. After the support plate 23 is installed, take the first magnetic block 32 and put it on the fixing rod 31, then take the non-woven fabric 1 and install it on the sawtooth block 21. The fixing rod 31 penetrates the non-woven fabric 1, and then take the second magnetic block 33 and put it on the fixing rod 31. The first magnetic block 32 attracts the second magnetic block 33 to move towards the direction close to the sawtooth block 21, clamping the non-woven fabric 1, so that the non-woven fabric 1 is not easily offset during use.

[0036] Furthermore, in order to improve the strength of the nonwoven fabric 1 during use, as Figure 1 As shown, the nonwoven fabric 1 has a glass fiber grid in the middle and polymer filaments on both sides.

[0037] The glass fiber grid makes the non-woven fabric 1 have higher strength and rigidity, and can provide better support and tensile strength, which enables the composite drainage net to withstand greater loads and geological stresses, and increases its service life and stability.

[0038] Furthermore, in order to further improve the strength of the non-woven fabric 1 , a plurality of spunbonded thermally bonded filament glass fibers 11 are fixedly connected inside the non-woven fabric 1 .

[0039] The spunbonded thermally bonded filament glass fibers 11 increase the load-bearing capacity and tensile strength of the nonwoven fabric 1 . At the same time, due to their good wear resistance, they can effectively resist soil erosion and damage, thereby extending the service life of the nonwoven fabric 1 .

[0040] 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.
