Prevent erosion by self-inserting concrete mats

In order to prevent erosion for works, Minh Tac Engineering Consultant Company Limited, Ho Chi Minh City has launched a self-woven concrete carpet, which can protect river roofs and irrigation works and deliver pine, preventing erosion by flow.

This type of carpet consists of 3 layers: The upper layer is concrete slab which is tightly coupled to shield the hydraulic impact on the ground. The second layer is a wire mesh woven together with concrete tablets to form a carpet. The third layer is a self-inserting footing system that covers the mounting joints and weight links. Layer 2 and 3 have the effect of replacing the stone cushion layer, 10 cm thick, reducing the background velocity, limiting the phenomenon of ground erosion.

Compared with steel gabion carpets, concrete mats linking bolts, concrete carpet of Betomat cables . have been applied in the country, the self-woven concrete mats have many advantages. Carpets are constructed on new technology lines, ensuring quality and reasonable price. The length depends on the length of the shoreline to be protected (maybe 10 to 100 m). Carpets are assembled continuously on land or on rafts, then raised to the necessary position so it is very convenient for construction.

Especially, this technology can successfully protect deep river banks up to -25m with soft soft ground, subsidence, serious landslides into stable river banks.

Carpets consist of special concretes, closely spaced, bonded by wire mesh and self-insertion, to cover gaps, withstand the effects of currents or underground waves . Large-diameter steel mesh, high strength, anti-subsidence raft. If later, when the wire mesh is rusted, the carpet will continue to work with a 3-way self-inserting link to maintain the stability of the building. The underside of the carpet has an anti-skid foot system, the upper surface of the carpet is a flat cement that can diversify patterns on the surface.

This technology has been successfully tested 114 m at An Hoa Ferry, Long Xuyen City; 560m at Long Xuyen Embankment in An Giang province; 705 m at Muong Chuoi embankment, Nha Be district, HCMC; embankment works of Vinh Binh, Ho Chi Minh City, Tan Long embankment, Tien Giang province .

According to experts, the river bank anti-erosion embankment according to the technology of spreading concrete self-woven carpet with high life expectancy, fast, investment cost reduced by 25-30% compared to the plan. Other structure.
