GEOTEXTILE CEMENTING SHELL AND METHOD OF ITS MANUFACTURE Russian patent published in 2017 - IPC E02B3/12 E02D17/20 

FIELD: construction.

SUBSTANCE: claimed group of inventions relates to means for providing reliable and durable protection of hydrotechnical, hydrological, industrial, civil, military construction objects to be erected, to prevent processes of shoreline soils weakening due to erosion caused by water current, action of coastal waves, exogenous processes, to strengthen soils on flanks and slopes, to prevent it from sliding down, which can be used on areas with composite terrain. A geotextile cementing shell is a structure consisting of two high-strength synthetic fabric webs 1 connected to each other, for example by sewing 2, forming a shell, which is then filled with a concrete mixture. By means of concrete laid in the shell, it is a three-dimensional structure of polymer materials, divided into sectors. Wherein the geotextile cemented shell is made closed and hollow, has the undulated uniform cross-section, this is achieved by quilting two webs 1 and sewing them around the perimeter. The structure is made of a polyester textile fabric with the surface density of at least 280 g/m², with the linear density of at least 87 tex threads, with at least one opening 3 made on the front side of the device, with a valve 4 installed in the opening by the sewing method. The valve 4 is represented by a woven hollow structure of a cylindrical shape and is made with the possibility to prevent the concrete mixture from leaving the shell cavity. The method of manufacturing the geotextile cemented shell is characterized by the application of one polyester fabric web 1 to the other, by fastening them together with sewn joints 2, of lockstitch or chain stitch, along the entire perimeter. In the case of using in the design a reinforcing polymeric mesh, it is located between two polyester fabric webs. Thereinafter, over the entire product area, the upper layer and the lower layer of the material are quilted with breaking down into sections in the staggered order in at least three rows. Along the perimeter, polyester bands or loops are sewn. Thereinafter, at least one opening 3 is cut in the upper web 1, in order to sew therein the preformed valve 4, also made of a polyester fabric.

EFFECT: reducing the material consumption of the device and simplifying the method of manufacture.
