Embodiment Construction

[0026] 1. The mobile soft anti-silting emergency non-metallic pavement of the present invention is a hollow knitted fabric between the plane fabric and the three-dimensional fabric. The thread has a specific balanced twist, which facilitates the process and improves the geotechnical properties of the fabric structure. The fabric is repeatedly rolled; the geotechnical parameters such as the geometric structure and effective pore size of the fabric do not change significantly, and the stable water permeability and filtration function is maintained. The hollow woven fabric is embedded with a number of non-metallic reinforcing ribs in the weft direction. The fabric has little deformation under tension, high strength and high rigidity, which is conducive to the fabric to play the role of film tension and control the subsidence of the foundation. The hole diameter required for reinforcement enables the hollow fabric to realize a standard and complete embedded reinforced fabric.

Abstract

The invention relates to a mobile soft anti-silting emergency non-metallic pavement, which is a hollow braided fabric between a plane fabric and a three-dimensional fabric. There are several weft non-metallic reinforcing ribs embedded inside the object; the warp and weft yarns are non-metallic fiber filaments, the middle of the non-metallic fiber filaments is a hollow structure, and there are several grooves distributed on the outer surface, and the grooves are connected with the hollow. It has the following characteristics: small weight, convenient and fast transportation and use, can be operated mechanically and manually, with fast operation speed, less personnel required, and low labor intensity; stable and reliable performance, long service life, wide application range, and can effectively overcome the Yellow River It can also effectively overcome soft and muddy land such as other rivers, lakes and coastal shoals; all materials are based on domestic production and processing, and the market has a wide range of sources.

Description

(1) Technical field [0001] The invention relates to a mobile soft anti-silting emergency non-metallic pavement. (2) Background technology [0002] The mobile soft pavement can overcome the shoals and soft and silt obstacles of rivers, lakes, coasts and other rivers and lakes in the middle and lower reaches of the Yellow River, quickly open up passages, and ensure the mobility of personnel, weapon technology and equipment. It can be used as road support equipment, military bridge (combined pontoon bridge) entrance and exit road support equipment, and can also be used as airport aircraft emergency repair and other support equipment. In the battle of crossing the sea and landing on the island, it can be used to overcome coastal shoals, ensure the loading of heavy equipment on our shore, and carry the equipment after arriving on the shore. It can also be used for road engineering support in emergency situations such as flood fighting and rescue. [0003] However, for the exist...
