Description

The utility model relates to the construction of underground structures, namely to public utilities with the simultaneous laying of communications in them: heat pipes, water pipes, electric and telephone cables, etc. The collector is located mainly below ground level or in a semi-buried position under the carriageway along the street and between houses .

The well-known urban collector (Engineering equipment of buildings and structures. Encyclopedia M .: Stroyizdat, 1994. - S. 199-200), the underground passage through which is made of waterproofing building material, for example, from prefabricated reinforced concrete blocks with drainage channels and brackets, and together communications laid inside the channel: heat pipe, water supply, electric and telephone cables, electric lighting, ventilation and other devices. After 200 ... 250 m, the collector is equipped with hatches and vertical stairs. The width of the passage in the collector is at least 70 cm, and the height is more than 2 m.

The disadvantages of the famous city collector are:

- time-consuming repair of communications, since in case of replacing and updating sections of the pipeline it is necessary to open a large amount of the soil surface, and then new laying the soil and, if necessary, asphalting;

- damage to the blocks during their dismantling, since reinforced concrete blocks are made integral (without a removable upper part of the block).

The technical result achieved by the implementation of the proposed utility model is to reduce the time for repair of communications.

To achieve a technical result in a reinforced concrete collector for the operation of underground utilities, containing an underground passage channel composed of waterproofing building material with drainage and brackets, equipped with hatches and vertical stairs, and laid inside the communication channel, namely heat pipe, water supply, electric and telephone cables, electric lighting, ventilation devices, according to the utility model, as a waterproofing building material underground reinforced concrete tubing with an opening in at least two side walls is used, while every 30-50 m of the channel 3-4 tubing is installed with a removable upper wall fixed to the side walls of the tubing due to recesses made at the lower edges removable upper wall and on the upper inner edges of the side walls of the tubing.

The removable upper wall of the tubing is made in the form of a pedestrian walkway with borders at the edges.

On the walls of the tubing there are embedded parts to which the brackets are welded.

The underground passage channel may contain tubing with switching and distribution nodes.

The collector contains drain sumps located at the bottom of the tubing and designed to collect groundwater.

The essence of the utility model is illustrated by drawings.

In FIG. 1 shows a layout of reinforced concrete tubing in a manifold; in FIG. 2 tubing with an opening in the side wall; in FIG. 3 tubing with a removable upper wall; in FIG. 4 fastening of the upper wall to the tubing.

The reinforced concrete collector for the operation of underground utilities (Fig. 1) contains an underground passage channel made up of waterproofed building material in the form of reinforced concrete tubing with drainage and brackets, with communications laid jointly inside the channel, namely heat pipe, water supply, electric and telephone cables, electric lighting, ventilation devices, and equipped with hatches and vertical stairs. Drains, brackets, communications, hatches and vertical stairs are not shown in the figures. The underground passage channel (Fig. 1) is composed of tubing with an opening in two side walls 1, tubing with an opening in three side walls 2, tubing with an opening in two side walls and a removable upper wall 3, tubing for switching and distribution nodes 4. All tubings are made of reinforced concrete.

Tubing is an element of the prefabricated lining of underground structures. Currently, the lining with tubing is most widely used during the sinking of mine shafts and subway tunnels. Its main advantage compared with lining of monolithic concrete and reinforced concrete is the ability to perceive rock pressure in the immediate vicinity of the face. Using the proposed utility model, it is proposed to use reinforced concrete tubing for underground utilities.

Tubing with an aperture in two side walls 1 alternates in the structure of the collector with other tubing, and is also used as a tubing adjacent to building 6 (Fig. 1). When branching an underground passage channel and connecting with tubing for switching distribution nodes 4, tubing was used with an aperture in the three side walls 2. Apertures 5 (Fig. 2) in the tubing are designed for passage of personnel installing communications and serving the collector.

Tubing with an aperture in two side walls and a removable upper wall 3 are installed at the rate of three to four tubing for every 30-50 m of the passage channel (Fig. 1-3). The removable upper wall of the 7 tubing is made in the form of a pedestrian walkway with borders at the edges and is located at the level of the lawn (Fig. 3). To raise the removable upper wall 7 on its outer surface there are loops (not shown in the figures). The ability to remove the upper wall 7 allows you to quickly and efficiently make emergency repairs of communications. The removable upper wall 7 is secured by recesses 8 (FIG. 4) made along the lower edges of the removable upper wall 7 and recesses 9 made along the upper inner edges of the tubing side walls 10 and 11. To cover the upper part of the tubing, the recesses 8 of the removable upper wall 7 are installed on the protrusions 12 and 13 of the side walls 10 and 11 of the tubing so that the protrusion 14 of the removable upper wall 7 fits into the recesses 9 of the side walls 10 and 11 broken a (Fig. 4) . The installation of the recesses 8 on the protrusions 12 and 13, as well as the protrusion 14 in the recesses 9, provides a removable upper wall 7 stability and protects it from shifting to the sides.

Tubing for switching and distribution nodes 4 (Fig. 1) also have walls with an opening 5 (Fig. 2). The number of walls with an opening depends on the location of these tubing in the manifold.

Each tubing has mounting loops 15 for ease of mounting and dismounting of the manifold (Fig. 3).

For a convenient arrangement of pipes and cables, on the walls of the tubing there are embedded parts 16 to which the brackets are welded (not shown in the figures).

The collector contains drainage sumps 17 (Fig. 4) located in the lower part of the tubing and designed to collect groundwater. The sumps 17 are made after about 50 m of the length of the underground channel.

Reinforced concrete collector for the operation of underground utilities is used as follows.

After the preparation of trenches of appropriate sizes, installation of reinforced concrete tubing begins (Fig. 1), after having previously painted with the tar that part of the tubing a that will be underground. Types of tubing designs during installation alternate. For a length of 30-50 meters of the underground channel, 3-4 tubing is mounted with openings and a removable upper wall in the form of a pedestrian walkway 3. At the branches of the underground passage channel, tubing with an opening in three side walls is installed 2. Tubes for switching and distribution nodes 4 are installed in parallel the main row of tubing and dock them with tubing having an opening in three side walls 2. The remaining tubing with an opening in two side walls 1. The joints of the tubing are sealed with waterproof sealant. Then, using the openings 5 (Fig. 2), the communications are mounted.

The proposed technical solution will reduce the time for repairing communications due to the removable upper wall of the tubing, located from each other every 30-50 m, and two or three openings in the side walls of the tubing.
