Abstract

FIELD: construction.

SUBSTANCE: method for laying pipelines through passage tunnels. The method for laying a pipeline through passage tunnels involves laying the pipeline in U-shaped trays covered with a slab on top. The trays are connected to each other using fasteners and placed one after another along the path of laying the central pipeline. In branches to residential buildings, trays with a rectangular opening are installed. Trays with the indicated rectangular opening are installed perpendicular to the trays, which are further extended to residential buildings for the purpose of laying the pipeline in them. Through this opening, the pipeline is diverted from the central pipeline to residential buildings.

EFFECT: simplifying the production process of laying pipelines, increasing the efficiency of pipe laying and simplifying the process of accessing the pipeline for the purposes of its maintenance.

Description

TECHNICAL FIELD

The claimed invention relates to the field of construction, in particular, to the technology of laying pipelines through passage tunnels.

BACKGROUND OF THE ART

A method of laying pipelines in channels is known from the prior art, in which concrete trays are placed in the developed trench to accommodate the pipeline, as well as utilities (SU 1560686, 04/30/1990). The disadvantages of this method are the complexity of the technological process for constructing channel walls for laying pipelines.

The design of concrete trays for laying pipelines, which are solid concrete structures, is known (SU 720107, 03/05/1980). The design is made of two U-shaped elements, one of which acts as a bed for placing pipes, and the second serves as a cover and is connected through fasteners to the lower one. The disadvantage of this solution is the increased load in the places where the trays are attached.

Solutions known from the prior art have both the above-mentioned disadvantages and do not allow the use of such approaches for laying pipelines in through tunnels, in particular, when supplying communications to residential buildings from the central highway.

SUMMARY OF THE INVENTION

The claimed invention overcomes the disadvantages inherent in solutions known from the prior art and offers a simple and reliable method for laying a pipeline through passage tunnels.

The technical result is to simplify the technological process of laying pipelines, increase the efficiency of pipe laying and simplify the process of accessing the pipeline for the purposes of its maintenance.

The claimed solution is achieved by implementing a method for laying a pipeline through passage tunnels, in which the pipeline is laid in U-shaped trays, covered with a plate on top, while the trays are connected to each other using fasteners and are located one after another along the path of laying the central pipeline, and in branches to residential buildings, trays with a rectangular opening are installed, which are located perpendicular to the trays on the central highway.

DESCRIPTION OF DRAWINGS

Fig. 1 illustrates a general view of a tray for laying a pipeline in a central main.

Fig. 2-Fig. 3 illustrates a general view of a tray for laying a pipeline from the central main to residential buildings.

Fig. 4 illustrates a general view of the layout of trays for laying a pipeline. IMPLEMENTATION OF THE INVENTION

In FIG. Figure 1 shows a view of the tray (10) for laying the pipeline in the central main. The tray (10) is a solid concrete U-shaped structure containing a bottom part (1), walls (2) and mounting loops (3). The trays (10) are placed in the prepared trench, for example, using a crane. Elements of the passage channel of the central highway, formed by trays (10), are mounted to each other using fasteners, for example, metal embedded parts, which are made in trays. You can also use bolts, staples, or welding of metal plates connecting the trays to each other.

After laying the trays (10) in the central pipeline, pipes are installed in them. Pipes in trays (10) can be mounted vertically or horizontally. After this, the tunnel cover is installed, which consists of concrete slabs covering the trays (10), which is held on their walls (2). The lid is attached to the trays using corners. Next, the tunnel is backfilled with soil (in some cases, partial backfilling with crushed stone or sand can be used) and further improvement is carried out.

In FIG. 2-Fig. Figure 3 shows the design of trays (20), which are used when arranging branches from the central highway. These trays, in general, repeat the design of the trays (10), with the difference that they contain an opening (4), made in a square or rectangular shape, through which the pipeline is diverted from the central highway to residential buildings. The opening (4) also allows for quick access to the pipes being laid, for example, for their repair. Trays (10) are installed perpendicular to the trays (20), which are further extended to residential buildings for the purpose of laying in them the pipeline supplied to the mentioned buildings, as shown in Fig. 4. Trays (10, 20) are fastened together with fasteners.

This principle of arranging tunnels for laying a pipeline allows for more efficient laying of pipes using walk-through tunnels, while implementing the quick and simple principle of forming trenches with laying concrete trays in them, which, based on their design features, make it possible to quickly and reliably place a pipeline in them, with This implements the principle of convenient formation of pipeline branches to residential buildings.

The proposed method of laying pipelines also makes it possible to compact the soil well for further improvement. In the future, this design will allow, even if it is necessary to open the tunnel, not to remove excess volumes of soil. The first installation of pipelines and other communications takes place in an open tunnel. After complete installation, the cover is installed and backfilling and landscaping are carried out. This scheme for laying a passage tunnel is less demanding in preparing the foundation. It can be done simply on the ground, as today the trays of impassable tunnels are laid.

The claimed method allows you to maintain and monitor the status of communications around the clock and all year round. Detect in advance the onset of an emergency in the tunnel itself and eliminate it.
