Embodiment 1

[0018] A kind of production technology of anti-flood geotechnical bag, it comprises the following steps:

[0019] PET polyester material is used to make polyester filament by high-strength and low-elongation spinning process. The obtained polyester filament has the advantages of small deformation and high strength, so as to ensure that the dam body will not be damaged due to the deformation of the bag body ;

[0020] After electrostatic elimination and warping, the polyester filaments are woven into bag fabrics. The woven bag fabrics have a high enough warp and weft density to ensure that the soil filled in the geotechnical bags will not be lost, and water can pass through freely, ensuring The dam is stable;

[0021] The fabric of the bag body is cut and sewn to make a geotechnical bag. The sewing thread is made of polyester filament thread of the same material as the bag body. The sewing density and tightness are strictly required to ensure that the seam is smooth and dense,...

Embodiment 2

[0025] On the basis of Example 1, the fabric of the bag body adopts the plain weave reinforced grid process to ensure that the same friction coefficient can be obtained in each direction. The plain weave reinforced grid adopts water absorption expansion lines, which greatly improves the friction coefficient of the bag body fabric Make sure the dam is stable.

Embodiment 3

[0027] On the basis of Example 1, the opening of the geotechnical bag is provided with a tie rope, and the tie rope is made of polyester filament ribbon of the same material as the bag body. The tie rope is soft and high in strength, ensuring that the tie rope The connection with the bag body is more reliable.

[0028] The flood control geotechnical bag made by the above-mentioned examples 1-3 has high strength, low elongation, strong deformation resistance, and can be loaded with 30kg of geotechnical bags. The stacking height can reach 15m without deformation, and the bag body remains intact; the comprehensive strength is excellent, Anti-puncture, anti-burst, can be used in complex geographical conditions, can effectively resist the damage of tree roots, stones, etc. Good stability and not easy to collapse; the bag body is densely clothed and the effective aperture is small to ensure that the filled soil will not be lost, thus ensuring the reliability of the dam body; acid an...

Abstract

The invention discloses a flood prevention geotechnical bag and a production process thereof. The flood prevention geotechnical bag is formed by tailoring and stitching bag body cloth, which is made of polyester filaments through a spinning process; the polyester filaments are made of PET polyester materials through a high-strength low-stretching spinning process; and stitching lines of a bag bodyadopt polyester filaments with the same materials with the bag body. The production process of the flood prevention geotechnical bag comprises the following steps: the polyester materials are spun through the high-strength low-stretching spinning process, and are spun as the bag body cloth by electrostatic elimination and warping; and the geotechnical bag is made of the bag body cloth through thetailoring and stitching process. The flood prevention geotechnical bag is high in strength, low in elongation, high in deformation resistance and excellent in comprehensive strength, resists punctureand breakage, and is high in friction coefficient between bag bodies, not prone to relative sliding, excellent in dam stability and not prone to collapse; and the bag body cloth is dense and small ineffective aperture to guarantee no loss of filled soil, resists acid, alkali and microorganism corrosion, is excellent in ultraviolet resistance, and resists aging.

Description

technical field [0001] The invention relates to the technical field of digital multimedia, in particular to a flood control geotechnical bag and a production process thereof. Background technique [0002] Dikes are an important part of the flood control engineering system, and it is extremely important to reduce flood losses by ensuring that dikes are overflowed and dealt with quickly when dangerous situations occur. In the flood season, emergency measures should be taken to prevent overflow, usually rushing to build sub-dikes and relying on sub-dikes to retain water. Bagged earth embankment is the most commonly used form in flood fighting and emergency rescue. Geobags are used for short-distance bagging and transportation: soil, gravel, sand and other materials can be filled in geobags, and materials can be obtained locally. Existing geotechnical bags are widely used: plastic woven bags, gunny bags or straw bags. Disadvantages of existing geotechnical bags: plastic woven ...
