The method of laying underground utilities

 

(57) Abstract:

The invention relates to the field strip and repair of underground utilities: city water, heat and other networks and cables for various purposes, laid in trenches, and may find application in construction and industries that exploit underground utilities. The technical result is the reduction of time and costs for renovation of underground utilities through accelerated access to these communications and exceptions work on beautification of the surface. This goal is achieved due to the fact that the method of laying underground utilities includes excavation of trench construction in its bottom channel for communications, strengthening the side walls of the trench to its entire depth, filling the trench and construction of surfaces. What's new is that the upper part of the fortified walls of the trench brought to a level surface and fill perform building blocks, located between the fortified walls of the trench with later retrieval when the repairs, and in the upper block having a trough-like shape, carry out construction of surfaces. 1 Il.

The invention of Anabela for various purposes, laid in trenches, and may find application in construction and industries that exploit underground utilities.

A known method of laying underground utilities (Pavlov N. And. and other "Boiler plants and heat networks", Moscow, stroiizdat, 1986, S. 195 - 197, Fig. XXII.6-XXII.7), including excavation of trenches, laying on its base communications (pipes, cables), backfill the trench with soil and the elevation of the surface (paving, planting of grass, shrubs).

The disadvantage of this method is that at each repair of the supplied communications need to break the trench, breaking the surface (lawns, alleys) and terrestrial communications (roads, sidewalks), and then, after each repair, restore and improve the surface above the trench.

Difficult access to communications for their repair and the need for refining the surface over the trench after each opening leads to increased time and cost for repair of communications.

The closest is the method of laying underground utilities, including excavation of trenches, construction in its bottom channel for communications, strengthening the side Munication when they repair destroy and remove surface treatment and ballast cushion, then take out the horizontal plate. The need to break the surface of the coating, and then restore it after the repair leads to increased time and cost for repair of communications. This is a disadvantage of this method.

The aim of the invention is to reduce time and cost for repair of underground utilities through accelerated access to these communications and exceptions work on beautification of the surface.

This goal is achieved due to the fact that the upper part of the fortified walls of the trench brought to a level surface and fill perform building blocks, located between the fortified walls of the trench with later retrieval when the repairs, and in the upper block having a trough-like shape, carry out construction of surfaces.

Strengthening the walls of the trench to its entire depth with the release of the upper parts of the walls on a level surface prevents the walls of the trench from caving, polsani, collapse, disintegration. This, in turn, allows for the repair to save from destruction adjacent to the wall surface and to exclude its subsequent improvement.

In addition t Ecevit saving design dimensions of the trench. And it allows to keep constant the necessary clearances between the fortified walls and building blocks and to provide the desired ease of extraction of blocks from the trench during the repair and expedited access to communications.

Filling the trench major building blocks that are located between the fixed walls of the trench with later retrieval, allows to reduce the time for the opening of the trench during its repair.

The overlap of the upper part of the trench-shaped unit containing the elements of the surface, such as asphalt, soil with growing lawn grass or shrubs, allows you to open a trench without disturbing the surface directly on it.

These new signs provide much faster access to underground utilities and allows you to perform repairs, excluding work on beautification of the surface, which allows to reduce time and reduce repair costs communications.

The invention is illustrated by the drawing, which shows a channel with communication in the context.

Consider the implementation of the method for laying communication the neck 1. The walls of the trench strengthen, for example, vertical walls 2 of the concrete slabs, so that the upper part of these fortified walls were flush with adjacent surface. The space between the walls of the trench 1 and the vertical walls 2 are filled in, for example, in the lower part of the soil 3, sand 4 gravel 5 and the outer part is covered with asphalt 6.

At the bottom of the trench build channel 7 for routing communications. In the channel of public communication 8 override it, for example, reinforced concrete slabs (and, if necessary, dampproof. Then fill the trench between the walls 2 building blocks of 10.

When you need insulation communications building blocks 10 and the gap between them and the walls of the trench 2 fill insulating material. In addition, the gap between the upper 10 and the walls of the trench 2, if necessary, additionally dampproof.

The upper part of the trench-shaped cover unit 11 with an asphalt top 12.

When laying communications, for example, under the lawns in the trough-shaped unit 11 fall asleep soil planted with lawn grass.

When repairing the communication is anouki block 11 with paved upper part of the repair ends, when the road surface becomes original appearance.

The proposed method can speed up access to underground utilities at their repair, to eliminate the time-consuming work to restore the surface and as a result reduce the time and cost of repairs.

The method can be applied to the whole road communications and its individual parts, for example, when crossing them with roads. In this case, the restoration of traffic on the road can be carried out in a short period of time because of work on paving it over a trench with communications and the adjacent surface are excluded.

The method of laying underground utilities, including excavation of trenches, construction in its bottom channel for communications, strengthening the side walls of the trench to its entire depth, filling the trench and construction of surfaces, characterized in that the upper part of the fortified walls of the trench brought to a level surface and fill perform building blocks, located between the fortified walls of the trench with later retrieval when the repairs, and in the upper block having a trough-like shape, carry out construction of surfaces.
