Abstract

A heating network pipeline containing a pipeline with thermal insulation and waterproofing, located on the embankment support, characterized in that the embankment support is made of a multilayer layer made of a gravel-pebble mixture provided with a drainage to drain water, the earth layer and on top of the protective-mechanical layer in the form of paving or sodding, the support-embankment is laid along the entire length of the pipeline, and the pipe insulation is made of reinforced concrete or expanded clay concrete.

Description

Pipeline heating networks.

The utility model relates to the field of construction and can be used in the construction of pipelines of heating networks.

A well-known pipeline, including longitudinally-movable supports in the form of a soil base and directional stops placed on both sides of the pipeline (AS USSR No. 609017, MKI 16 3/18, EI№ 20, 1978).

However, the known pipeline has a complex structure, requires the construction of special stops.

The closest in technical essence is a pipeline with a low elevated laying, including a pipeline with thermal insulation and waterproofing and a protective - mechanical layer made of aluminum or roofing iron, placed on an earthen embankment - support (I.P. Petrov, V.V. Spiridonov, Subsoil, - M.1986.186 p.).

However, the reliability of the known pipeline is insufficient. The pipeline fails due to the destruction of the waterproofing layer and suspended thermal insulation in the jamming areas from soaking of the protective - mechanical layer, and in open areas due to the theft of aluminum or roofing iron in the first year of operation of the pipeline. In addition, the cost of the known pipeline is quite large.

The objective of the proposed utility model is Reliability, an increase in the life of the pipeline and a decrease in its cost.

The solution of the problem is achieved by the fact that the pipeline of heating networks includes a pipeline with a heat-insulating layer and a waterproofing layer, placed on an embankment - a support that runs along the entire length of the pipeline, is multilayer, the layer adjacent to the pipe consists of a gravel-pebble mixture, equipped with a drainage for drainage water, then there is an earthen layer and on top is a protective - mechanical layer in the form of paving or sod. The heat-insulating layer is made of reinforced concrete or expanded clay concrete.

In FIG. I shows a cross section of the proposed pipeline. The pipeline includes pipe I with thermal insulation 2 and waterproofing 3, the support - the embankment consists of a gravel - pebble layer 4, with drainage 7, a ground layer 5 and saiiltfMe mvshashchechey layer 6, made in the form of paving or dressing.

The pipeline works as follows:

Protective - mechanical layer b protects from mechanical EXPOSURE, precipitation and sunlight not only earth and gravel - pebble layers, but also waterproofing layer 2 and thermal insulation layer I, which eliminates the use of expensive suspended thermal insulation and applies thermal insulation from reinforced concrete or expanded clay concrete.

The pebble and pebble layer reduces the friction forces when the pipeline is pinched in the support - the embankment. Drainage removes ground and surface water beyond the gravel - pebble layer and contributes to the rapid drying of thermal insulation. Support - the embankment serves as a protective layer for the pipeline and completely eliminates the use of expensive aluminum or roofing iron.

Thus, the proposed device of the pipeline heating networks ensures reliability, due to the high protective and mechanical properties of the multilayer support - embankment, increases the service life of the pipeline and reduces its cost.
