Abstract

The invention relates to the construction and can be used in the construction of underground utilities in order to reduce the width of the land strip allocated for work in the constrained conditions of streets and reduce the damage to their improvement. The method is carried out as follows. Trench 1 is developed and tray 2 of the channel and wall 3 is raised to the top of the trench. After the walls 3 are erected, they are fastened with internal spacer elements 4, and then before the pipelines are installed, backfilling 6 is carried out with the formation of at least one side of the passage channel and assembly sites. In the case of laying pipelines with sections that are longer than the distance between the inner spacer elements 4, they are removed in a section of length equal to the section length, walls 3 in this area are anchored to the soil by backfilling with additional spacers, and after the installation is completed, additional spacers are removed and establish the internal spacers 4, the overlap of the channel and restore the road surface. 2 hp ff, 3 ill.

Description

The invention relates to the construction and can be used in the construction of underground utilities.

The aim of the invention is to reduce the width of the land strip allocated for work in the cramped conditions of the streets, and to reduce the damage to their improvement.

Figure 1 shows the moment of laying the pipeline after installation of the tray and the walls of the channel and backfilling of the sinuses; Fig. 2 illustrates the moment of laying the pipelines in long sections; in FIG. 3, the moment of completion of all works.

The method is carried out as follows.

Trench 1 is developed and tray 2 of the channel and wall 3 is raised to the top of the trench. After the walls 3 are erected, they are loosened by internal discrete spaced elements 4, after which prior to the installation of the pipelines 5, backfilling 6 is carried out with formation of at least one side of the passage channel and assembly sites.

In the case of laying pipelines in 5 sections, longer than

The connection between the internal spacer elements 4, part of the internal spacer elements 4 in a length equal to the length of the section is removed, the upper parts of the walls 3 of the channel in this area anchors the additional spacers 7 to the soil of the backfill 6, and 7, internal spacer elements 4 are removed and installed in this area.

Upon completion of the installation of pipelines and other equipment of the channel, conducting inspections and testing them, install the overlap of the channel 8 and restore the pavement 9 directly on the channel overlap or on the ballast cushion 10.

If the project requires other works, for example, waterproofing, they are carried out in the appropriate period of the construction of the canal in parallel with the works described.

The installation of the bottom of the walls and spacers can be performed using special equipment mounted above the trench, which is moved forward along the channel along the channel as the sections are assembled into a trench and backfilled.

The method allows to improve the organization of work and production conditions by creating assembly platforms and passages for motor vehicles with mechanisms directly adjacent to the canal, as well as reducing the amount of damage and destruction of street improvement elements due to the cessation of riding shops and mechanisms on sidewalks and lawns. In addition, repair and replacement of pipelines significantly reduce the amount of work and damage to the street pavement, which makes it possible to carry out repair work by opening the canal with the removal of the overlap and use of the whole complex of mechanization of heavy work

repair with the supply of materials through hatches and installation windows and the implementation of repair work in a closed, tight channel space with a predominance of manual heavy physical labor.

Claims (3)

1. A method of laying pipelines in the ground, including developing a trench, erecting a channel tray and walls to the top of the trench, installing pipelines with the subsequent erection of the channel in the ground surface and backfilling the trench, in order to reduce the width of the land strip, allocated for the production of works in the constrained conditions of the streets, and reducing the damage to their improvement, after the walls are erected, they are fixed with internal discrete spaced elements, and backfilling is carried out before the installation of the pipelines with the formation of at least one side of the passage channel and assembly sites. 2. Method pop.1, which is different from the fact that the pipelines are laid in sections of length not exceeding the distance between the internal spacer elements along the length of the channel. 3. A method according to claim 1, characterized in that the pipelines are laid in sections of a length exceeding the distance between the inner spacer elements along the channel length, and prior to the placement of each section, part of the internal spacer elements in the section equal to the length of the section are removed, the upper parts of the canal walls in this area, anchor to the soil backfill with additional spacers, and after the section is installed, the additional spacers are removed and internal spacers are installed in this area.
