Protection works to reshape banks with geogrids
Protection works to reshape banks with geogrids
In torrential events, the phenomenon of lateral erosion can occur on the banks of the rivers and the phenomenon of scour in the river bed, causing the detachment and dragging of alluvial material, generating overflow of the tributary, detachment and removal of soil mass. , affecting the crops and properties surrounding the area. To have control, it is necessary to implement protection works to reshape the banks and control the overflow of the channel.
Regarding the phenomenon of scour that occurs in rivers, a situation that mainly damages the stability of any work, it is important to implement solutions that allow controlling the removal and transportation of the material, given the hydraulic conditions of the channels, specifically in those aggressive rivers. with abundant transport of large detritus.
Use of site materials to form protective structures with geogrids
The possibility of using the materials from the site to form structures of protection flexible and highly resistant makes the use of geogrids in the articulated system GEOESTERA It is more economical and versatile than conventional solutions such as RipRap.
For this reason, GEOSTERNAL GEOMETRIC GRIDS adapt to the shapes of the existing terrain and, due to their flexibility, allow for more efficient scour control compared to rigid type protections such as concrete. The effectiveness of the system results from the following fundamental characteristics that are achieved by confining the rockfill or alluvial material from the site in the GEOESTERA GEOMILLA containers.
Solutions with geogrids
In the first instance, a continuous mass of high porosity is considered. Likewise, they offer flexibility and hydraulic stability in those works implemented for marginal protection in rivers.
They have high durability and long-term resistance capacity of GEOMESTER GEOMETRIC GRIDS. They also adapt to any irregular surface and unlike other alternatives, their installation is practical and adaptable to the available construction equipment.
The exclusive G5 multifilament, made of high tenacity polyester and the coating with a copolymer in the GEOSTER GEOMIME, make the articulated system able to tolerate any natural environment of chemical, biological and mechanical degradation and without being suitable for salt water environments. and aggressive environments where other materials deteriorate quickly.
Likewise, the increase in tractive forces generates greater drag of material, which can directly impact the protective structures, compromising their durability. That said, to prolong the durability of this protection, it is recommended to use a coating that helps protect the structure from these torrential events.
The coating can be done with our textile form ARTICULATED COLCHACRETO, is 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 gravity element to be used to form the marginal protection. , giving a macro texture similar to pebbles.
