Description

Technical field

The technical solution relates to a self-supporting cylindrical tank, settled primarily into the ground horizontally, intended for cesspools, septic tanks, drinking water tanks and as storage tanks for chemicals.

BACKGROUND OF THE INVENTION

Technical solutions of tanks are known, for example according to CZ PV 2004-333 relating to a watertight, rigid, cylindrical underground tank and method of its production, according to CZ industrial design registration number 32547 concerning a tank for placement in the ground and further to CZ 16426 Ul, tanks are mostly settled on a concrete slab, the disadvantage of which is a flat bottom. During rains, the level of groundwater around the tank increases because the excavation has disrupted the structure of the bottom of the soil, creating a bathtub. Into this water seeps more easily and is filled with surface water faster than the surrounding soil and pushes the surface of the tank. This is the cause of occasional deformation of the bottom, resulting in damage to the shell and impermeability of the tank.

The essence of the technical solution

The aforementioned drawbacks are largely eliminated by a self-supporting cylindrical tank according to the invention, which consists of a shell provided with bulging and / or planar faces at the ends, the shell being provided with at least two stiffeners fixed perpendicular to its axis, with at least two feet fixed at the bottom perpendicular to its axis and at the top by at least one inspection port. An inlet or outlet opens into one of the faces or sheath. The fronts are reinforced from the inside. The control entrance is provided with reinforcing wedges. The shell of the self-supporting tank is provided with at least two longitudinal reinforcements. One overflow bulkhead is mounted inside the shell of the self-supporting tank. The shell has a circular cross-section. The sheath has an elliptical cross-section. Sheath reinforcements are made of metal profiles. The inspection inlet is provided with a lid. The reinforcement is fixed from the inside of the shell. The individual parts are joined by welding and / or gluing.

The advantage of the tank according to the technical solution is its self-supporting construction; Fixing the septum with overflow inside the shell of a self-supporting cylindrical tank creates a two or more chamber septic tank or cesspool. The self-supporting tank according to the technical solution enables easy transport and storage in the terrain.

Overview of the figure in the drawing

The technical solution will be explained in more detail by means of a drawing showing a side view of a self-supporting cylindrical tank.

Examples

The self-supporting cylindrical tank intended for horizontal placement is formed by a shell 1 of circular cross-section, provided at the ends with convex and / or planar faces 2 and 2. The shell 1 is provided with at least two stiffeners 3 reinforcing it and fixed perpendicularly thereto. longitudinal axis. At least two feet 4 perpendicular to its longitudinal axis are fixed to the tank shell 1 at the bottom. A control inlet 5 opens into the tank shell 1 at its upper part. The inlet 6 leads into the tank front 2 '. The ends 2 and 2' of the self-supporting tank are provided with reinforcement 7 from inside. The inspection inlet 5 of the self-supporting tank is provided with reinforcing wedges 8.

The reinforcements 3 of the shell 1 of the self-supporting tank are made of metal profiles, for example of stainless profiles. The inspection input 5 of the self-supporting tank is provided with a lid 12. The self-supporting tank reinforcement 3 is fixed from the inside of the housing 1, for example by rivets, and covered from the outside of the housing 1 by a cover.

- 1 GB 22341 U1

The shell 1 of the self-supporting tank is provided with at least two longitudinal stiffeners 9.

The self-supporting tank according to the technical solution is made of thermoplastic materials.

The connection of the individual parts of the self-supporting tank is carried out by conventional technology, either by heat welding or by glued connection.

Another possible solution, which is not shown, is a self-supporting tank whose shell 7 has an elliptical cross-section.

Another possible solution, which is not shown, is to provide a barrier 10 with an overflow 11 inside the housing 1 of the self-supporting tank and the housing 1 being provided with two inspection ports 5. This results in a two-chamber septic tank.

The inlet or outlet 6 can also be introduced into the housing 1.

The ends 2, 2 'are fastened to the shell 1 of the self-supporting tank from the inside.

The ends 2, 2 'are fastened to the shell 1 of the self-supporting tank from outside.

The cross-section of the tank is chosen according to the depth of the tank and possibly the type of rock into which the tank settles.

Industrial applicability

The self-supporting cylindrical tanks according to the invention can be used as reservoirs for drinking water, for chemicals, as cesspools and simple septic tanks and multi-chamber septic tanks and as reservoirs for chemically contaminated water.
