Technical Field

[0001] The utility model relates to the technical field of anti-seepage composite geotextiles, in particular to an anti-seepage composite geotextile. Background Art

[0002] Geotextile, also known as geotextile, is a permeable geosynthetics made of synthetic fibers by needle punching or weaving. The anti-seepage composite geotextile is a film layer composited on the basis of geotextile to improve the anti-seepage effect of the geotextile.

[0003] In the existing water conservancy construction and building construction processes, multiple geotextiles are laid side by side. The geotextile covers one side of the adjacent geotextile or is covered under the adjacent geotextile. The friction between the two geotextiles is used to avoid misalignment after covering. However, this method is applicable to flat land, but not to some slope protection. Therefore, it is necessary to design an anti-seepage composite geotextile to solve the above problem.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-4A seepage-proof composite geotextile comprises a first non-woven geotextile 1, a first film layer 10 is arranged at the lower end of the first non-woven geotextile 1, a second non-woven geotextile 11 is arranged at the lower end of the first film layer 10, a plurality of connecting mechanisms for connecting to soil are arranged on the first non-woven geotextile 1, the connecting mechanisms comprise a plurality of connecting cloths 2 arranged on the first non-woven geotextile 1, two limiting holes 15 are arranged at the upper end of the connecting cloth 2, a baffle 3 is arranged at the upper end of the connecting cloth 2, and a second through hole 7 is arranged at the upper end of the baffle 3.

[0023] The connecting cloth 2 is provided with a limiting mechanism for limiting the position of the blocking piece 3 . The limiting mechanism comprises a cloth sleeve 5 arranged on the connecting cloth 2 . A first through hole 6 is formed at an upper end of the cloth sleeve 5 .

[0024] In the utility model, a second film layer 12 is provided at the lower end of the second non-woven geotextile 11, and a woven geotextile 13 is provided at the lower end of the second film layer 12. Woven geotextile has better strength and durability than non-woven geotextile, and can improve the strength and durability of the overall geotextile.

[0025] In the utility model, an I-shaped ring 9 is provided on the connecting cloth 2, and a limiting ring 14 is provided on the side wall of the I-shaped ring 9. When two adjacent geotextiles are stacked, the I-shaped rings 9 on the two geotextiles can be connected by ropes. The I-shaped ring 9 is riveted under the limiting ring 14 by a T-shaped ring, so that the connecting cloth 2 is not easily damaged by being pulled.

[0026] In the utility model, two first Velcro strips 4 are provided on the upper end of the connecting cloth 2, and two second Velcro strips 8 which can cooperate with the first Velcro strips 4 are provided on the upper end of the connecting cloth 2, so that the connecting cloth 2 will not leak too much after the whole geotextile is rolled.

[0027] In the utility model, the connecting cloth 2 is made of wear-resistant cloth, so that the connecting cloth 2 is more wear-resistant, and the baffle 3 is made of stainless steel material, so that the baffle 3 has better corrosion resistance and is convenient for recycling.

[0028] When in use, a geotextile is first spread on the ground, and ground nails are driven into the baffles 3 on the multiple connecting fabrics 2 of the first non-woven geotextile 1, so that the first non-woven geotextile 1 is firmly fixed on the ground, and then a part of the next first non-woven geotextile 1 is covered on the first non-woven geotextile 1 on the ground (as shown in the figure), and ground nails are nailed on the left side of the first non-woven geotextile 1 to fix the position of the first non-woven geotextile 1. In this way, a large number of geotextiles are covered on both sides of the first first non-woven geotextile 1 in turn. Since multiple first non-woven geotextiles 1 have one or both sides fixed by ground nails, the side without ground nails can be tied with a rope on the baffle 3, and the other end of the rope is tied to the connecting fabric 2 of the adjacent first non-woven geotextile 1, thereby greatly improving the deformation resistance of the geotextile after covering, playing a better role in protecting the soil, and indirectly achieving the purpose of preventing leakage;

[0029] A rope can be tied inside the I-shaped ring 9 of a first nonwoven geotextile 1, and then the rope is stretched to the I-shaped ring 9 on the other side of another first nonwoven geotextile 1, so that Figure 1 The right side of the first non-woven geotextile 1 at the upper middle end can not be easily moved, which is more solid than the method of preventing the movement of two geotextiles by friction, thereby improving the rationality of the device design.

[0030] 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 practical concept of the present invention, which should be covered by the protection scope of the present invention.
