Geotextile mitigation works
Geotextile mitigation works
In torrential events, the phenomenon of lateral erosion can occur on the river banks, causing the detachment and dragging of material that generates overflow of the tributary, affecting the crops and land adjacent to the area. For control, it is necessary to implement mitigation works with geotextiles such as spikes or spurs, which allow the dissipation of energy and the channeling of the flow back to its central axis.
Geotextiles, an innovative and cost-efficient solution
The spurs, considered as gravity structures, can be built with geotextile tubes HYDROTUBE, thanks to the fact that they are tubular containers with high resistance fabric HYDROTEXwhich is hydraulically filled with a fluid mixture of sand and water. These shaped structures have high resistance to puncturing and tearing, high modulus of deformation, an adequate balance between opening size, permittivity and percentage of open area, confining the fine material and at the same time allowing the water flow to exit; they are also supported on the site soil when dry or under water on another geotextile also made in HYDROTEX which serves as an anti-scour mantle.
Geotextile solutions that improve the service life of projects
The increase in traction forces generates greater sediment entrainment, which can impact the structure, generating an abrasive process and compromising its durability. In addition, the spurs are prone to failure due to tip scour, and this is a phenomenon that can be pronounced once the drag and scour conditions in the riverbed increase, generated by fluvial dynamics. That said, to prolong the durability of this protection, the use of a coating that helps protect the structure from these torrential events is recommended.
The cladding can be done with textile form ARTICULATED COLCHACRETO, which becomes a very good alternative, thanks to its system of blocks connected by means of tensioners that are embedded in the concrete, generating a continuous coating that is articulated to accommodate the shape of the building. HYDROTUBE, giving a macro texture similar to boulders.
