Description

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.

Of the types of drainages used in the Russian Federation, in the field of reclamation and artificial lowering of the groundwater level, shallow and deep drainages made of free-flowing natural and geosynthetic materials, as well as drainages from ceramic, asbestos-cement and polyethylene pipes, are actively used and used.

The aforementioned drainage pipes produced in the Russian Federation for the needs of land reclamation and dewatering are limited by the conditions and possibilities of use, in the "declared area", due to:

- high cost, drainage pipes, with the laying of pipelines "open / trench" in the ground;

- the lack of the possibility of laying pipelines, from drainage pipes, "closed / trenchless" method in the ground.

The closest solution to the claimed technical solution is a solution that meets the conditions of GOST 54475-2011 - "National standard of the Russian Federation" Polymer pipes with a structured wall and fittings for them for external sewage systems ", introduced in 2012-05-01, Moscow.

The disadvantages of this technical solution are:

- the lack of the possibility of laying pipelines from drainage "gravity" pipes, "closed / trenchless" method in the ground;

- high cost, drainage pipes, with the laying of pipelines "open / trench" in the ground.

The problem to be solved by the declared utility model is to create and use a product that meets modern requirements in terms of cost, ease of manufacture, durability, manufacturability in the construction and operation of melioration and dewatering systems.

The task is solved by making a drainage product - a stuffed shell, in the form of a "sleeve" made of polyethylene mesh with a cross section of 2.5 × 2.5 × 1.0 mm, 150 mm in diameter, 3 to 12 meters long, filled with expanded clay gravel fractions 10-40 mm and closed with a plug on the connecting piece made of polyethylene pipe. The product is placed in the drained soil using a trenchless method using horizontal directional or directional drilling (HDD and HDD), and the products laid in the ground are combined into a single drainage system for reclamation or dewatering in the soil.

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.

The utility model is illustrated by sketches that do not cover the entire scope of the claims of this technical solution, but are only illustrative materials of a particular case of implementation:

FIG. 1 is a longitudinal view of the product.

FIG. 2 - longitudinal section of the product "a-a".

FIG. 3 is a cross-section of the product "b-b".

FIG. 4 is a view from the end of the product "c-c".

FIG. 5 - unit 1/1 of the product with a "plug".

FIG. 6 is an isometric view of the product AA.

FIG. 7 - unit 1/2 of the product - "plug".

FIG. 8 - unit for connecting related products.

Drainage casing stuffing is made as follows:

- As a material for the shell, a polyethylene mesh with a cross section of ≥2.5 × 2.5 × 1.0 mm, the width and length of the workpiece, depending on the declared dimensions of the product, is used.

- Blanks for the product are made with one- or three-cavity reinforcement made of mesh with a strip width of 15-20 mm and a section of ≥2.5 × 2.5 × 1.0 mm for the entire length of the product.

- The casing - "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, with dimensions depending on the design solution.

- The shell - "sleeve" is filled with expanded clay gravel of fraction 10-40 mm with the installation of "plugs" at the ends of the "sleeve".

- The casing, before and after filling, is closed with a plug on the connecting element made of polyethylene pipe, selected depending on the volumetric weight of the product and the cross-section of the polyethylene mesh.

Drainage systems are built from the drainage casing rammed products of the described design, connecting separately the ends of adjacent products with the help of connecting elements made of polyethylene pipes by the method of thermal heating, butt-joint or couplings with heating elements, put on the junction of adjacent products. Drainage casing ramming product is intended for collection and transportation of underground groundwater and water mixtures over a short distance.

The main method of laying drainage shell ramming products is HDD (horizontal directional drilling) and HDD (directional drilling). The accepted methods of laying pipelines make it possible to reduce to a minimum the volume of "open" earthworks and, with them, other non-production costs.

The declared design of the drainage casing rammed products allows the product to be transported quickly and technologically to the place where the drains are laid and, during the construction process, to minimize the disturbance of the natural earth cover, and in the construction sites, disturbance of landscaping and landscaping. In addition, the use of the declared products significantly reduces the cost of construction of amelioration and dewatering systems.
