Drainage casing padded product (DONI-2)

摘要

The utility model relates to the field of land reclamation and artificial lowering of the level of ground (aggressive and non-aggressive) waters with natural transportation of water or water mixture over short distances.;Drainage casing stuffed product is made in the form of a "sleeve" of a polyethylene mesh with a cross section of ≥2.5 × 2.5 × 1.0 mm, a diameter of 150 mm, a length of 3 to 12 meters, filled with expanded clay gravel with a fraction of 10-40 mm in accordance with GOST 32496-2013 of 12/30/2013;For each declared product, a blank for the shell is made in advance from a polyethylene mesh with the width and length of the blank, depending on the declared dimensions of the product.;To strengthen the shell for mechanical strength, blanks for the product are made with three- or five-cavity reinforcement from a mesh with a strip width equal to 15-20 mm and a section of ≥2.5 × 2.5 × 1.0 mm for the entire length of the product.;The working shell - "sleeve" is made using moisture-resistant glue, gluing two sides of the mesh along the length and along the perimeter of the connecting element made of polyethylene pipe, in size depending on the design solution.;Vibro-mechanical method is used to fill the shell - "sleeve" with expanded clay gravel of fraction 10-40 mm with the installation at the ends of the "sleeve", on both sides, "plugs".;Before and after filling, the casing is closed using a plug of a connecting element made of a polyethylene pipe, selected depending on the total weight of the product and the cross-section of the polyethylene mesh.;Drainage casing rammed products are connected to each other using polyethylene pipe connecting elements connected by butt thermal heating or a detachable polyethylene sleeve with electric heating elements, put on at the junction of adjacent products.;The technical result is achieved by selecting the optimal diameter and length of the utility model, the cross-section of the polyethylene mesh "sleeve" and the bulk weight of the expanded clay gravel filler, taking into account the drained soil and the depth of the utility model, affecting the mechanical strength of the shell when laying the utility model in a "closed / trenchless" way using HDD or HDD.
