Implementation of the technical solution

A device for underground transportation or storage may be intended to transport (wire) liquid, gas or bulk products. Then it is made in the form of a pipe (Fig. 1, 2).

The device for underground transportation or storage can be intended for underground storage, accumulation, sedimentation (sticking) of liquid, gas or bulk products. Then

- 1 029807

it is made in the form of a tank (Fig. 3).

The device for underground transportation or storage contains a single-layer body (1) of a closed profile. It is advisable to make the body smooth, that is, such that the curve of its cross-section (profile) does not have breaks of its first derivative. It is desirable to make the body cylindrical, in this case the profile of the body is a circle. It is permissible, for example, to make the body conical, oval, barrel-shaped.

The body is made of a polymeric material, such as polypropylene, polyethylene, polyvinyl chloride.

To give the body the necessary rigidity attached to it reinforcing coils (2). Reinforcing coils (2) are reinforcement (3), placed completely inside the tube or tubes (4) of the same polymeric material from which the body (1) is made. The coils (2) can be made in the form of rings or spirals. The coils (2) can be placed both outside and inside the case.

Armature (3) in the claimed device is an element that perceives tensile and compressive loads, and the main loads are compressive. The armature (3) is made in the form of a wire of solid section or in the form of a pipe, that is, in the form of rolled solid or hollow section. In the latter case, it is possible to organize the supply of liquid or gas through the above-mentioned pipe fittings or place electrical wires inside it. It is possible to use rebar (3) with a smooth outer surface or with a periodic outer surface. The reinforcement (3) can be made of steel, fiberglass or other composite material.

The tube (4) performs the function of protecting the fittings from external influences and, at the same time, the function of uniform mechanical connection of the fittings with the housing. To prevent corrosion of the reinforcement (3), it is advisable to make the space inside the tube (4) tight.

Due to the fact that the predominant loads on the claimed device after its placement under the ground are compressive, when placing the reinforcing coils (2) outside the body (1) of the tube (4) it is required to be welded to the body (1) along the entire length. When placing the reinforcing coils (2) inside the body (1) of the tube (4), it is sufficient to weld to the body (1) in several places, not along the entire length.

In the manufacture of the device, the bending of the blank for reinforcing coils under the shape of the surface of the body is performed after inserting the reinforcement into the tube. Therefore, making the body surface smooth (for example, cylindrical) avoids the need to bend reinforcing coils with a small radius of curvature, which can lead to the presence of cracks in the tube and reduce its protective properties.

Examples of specific performance

Example 1. For the purpose of organizing an underground storm sewage system, the proposed device is made in the form of a round polypropylene pipe with a diameter of 2000 mm and a wall thickness of 12 mm. Reinforcing coils are made in the form of a single spiral with a pitch of 400 mm and fixed outside the case. The reinforcement is a fiberglass wire of solid section with a diameter of 18 mm.

Example 2. For the organization of underground water storage with a volume of 50 cubic meters, the claimed device is made in the form of a polypropylene tank (Fig. 3). The body (1) is made with a cylindrical diameter of 2.4 m and a length of 11 m. The wall thickness of the body is 10 mm. The housing is located underground horizontally.

Reinforcing coils (2) are made in the form of rings and fastened outside the body with a pitch of 0.45 m. The armature is a steel wire with a diameter of 18 mm, placed inside a polypropylene tube. The ends of the reinforcement are not welded and have a gap.

The ends (5) of the body are made in the shape of a truncated cone with a small base diameter of 0.75 m from the same material from which the cylindrical part of the body (1) is made. This form of the ends has a high rigidity compared with flat ends. In the places of fastening the ends to the cylindrical body inside the body, polypropylene stiffening corners (6) are installed along the entire circumference with a pitch of 0.63 m, welded to the body and the corresponding end.

Outside, the ends (5) are provided with beams of rigidity (7) made of polypropylene strips 50 mm wide.

In the upper part, at one of the ends, the case is provided with a polypropylene neck (8) with a diameter of 0.64 m and a height of 1.3 m, with a closed lid (9). Reinforcing coils (2) in the form of rings are also made on the neck (8). They are fixed on the outside of the neck with a pitch of 0.35 m. The armature of the coils (2) on the neck is a steel wire placed inside the polypropylene tube.

A supply pipe (10) (socket) is fixed at the end in the upper part, and a discharge pipe (11) is located at the opposite end in the lower part.

On the case (1) four nylon transport loops (12) are fixed.

The body (1), the ends (5), the neck (8) with the cover (9), the beams of rigidity (7) and the fastening of the transport loops are made of polypropylene sheet.

The ends (5) are welded to the inner surface of the cylindrical part of the body (1) (Fig. 4). A penny (13) in the small base of the end (5) is welded to this end inside the tank with the help of the inner ring (14), which gives additional rigidity to the structure in this place (Fig. 3, 5). Cover (9)

- 2 029807

throat (8) is flared (15) (Fig. 6). The neck (8) is inserted into the body (1) (Fig. 7). The inlet pipe (10) is fixed horizontally (Fig. 8).

Example 3. For the purpose of organizing an underground sewage well, the claimed device is made in the form of a polypropylene pipe. The body is made cylindrical with a diameter of 1.2 m and a height of 4 m. The wall thickness of the body is 8 mm. The housing is located underground vertically.

Reinforcing coils are made in the form of rings and fixed inside the case with a step of 0.5 m. The reinforcement is a steel wire with a diameter of 12 mm, placed inside a polypropylene tube. The tube of each reinforcing ring is welded to the body in fragments in 4 places. The length of one continuous weld is 10-15 cm.

The implementation of the proposed technical solution is not limited to the above examples. In particular, the reinforcing coils can be placed simultaneously both inside and outside the case; reinforcing coils can be made in the form of a double helix.

Order of use

Before placing the claimed device in the right place, dig a pit and arrange its bottom in accordance with the operating conditions of the device. For example, to locate the pipeline, the bottom of the pit is covered with a layer of sand. To accommodate large-capacity tanks, the bottom of the pit is covered with a layer of sand, a layer of rubble and concreted, i.e. make a concrete base.

At the bottom of the pit install the device and cover it with soil. Due to the fact that the claimed device is reinforced, there is no need to cement or concrete the walls of the pit.

In the case when the device remains empty, squeezing forces act on its walls from the side of the ground. This squeezing force is transmitted through the pipes to the fixture, the elastic limit of which is much higher than the acting forces. The armature does not allow the walls to deform. When the reinforcement is placed inside the housing, the forces of the impact of the soil on the housing are transmitted to the tube along the entire length of the contact between the tube and the housing, so there is no need to fasten the tube to the housing for the entire length. When the reinforcement is placed outside the housing, the squeezed wall of the housing entrains the tube with the reinforcement located inside it. Therefore, fixing the tube to the body along the entire length plays an important role. The lack of welding of the tube to the body will lead to the fact that in this area the effect of the soil will not be transferred to the fixture, and the wall of the body in this place will be deformed.

Thus, the placement of reinforcing coils inside the case has advantages when considering the issue of ensuring the rigidity of the structure. However, this placement has a flaw. Reinforcing coils located inside the housing are obstacles when moving liquid or other products inside the device or during installation / dismantling of equipment located inside the housing. For this reason, the placement of reinforcing coils outside will be more preferable when it is necessary to ensure the smoothness of the surface inside the device.

Filling the device with water or other liquid, as well as with bulk solids fully or partially compensates for the forces of ground impact on the device case.

Due to the fact that the fittings and tubes are made of different materials, the differences in their thermal expansion are compensated by the presence of gaps. In this case, the ends of the reinforcement are not connected, and the length of the tube is greater than the length of the reinforcement.

Industrial Applicability

The claimed technical solution is implemented using industrially manufactured devices and materials, can be manufactured at any industrial enterprise and will find wide application in the field of engineering systems.
