Background
Municipal pipe networks are important infrastructure and life lines of cities. Municipal pipe networks typically include electric, telecommunications, network, communications, heating, gas, storm water and sewage drainage, among others. In order to ensure the normal operation of the municipal pipe network, not only the standardized construction is carried out on the construction of the pipe network, but also the daily maintenance work of the pipe network is required to be done.
For a pipe network buried in a municipal road, during construction, a pipe chase is generally excavated, then a pipeline is installed in the pipe chase, and then the pipeline is buried in the pipe chase by backfilling. During the backfilling process, the backfilled soil is provided with stones or other sharp objects, so that the pipelines are damaged, and the pipelines are cracked and damaged. The traditional pipeline buried has a poor heat insulation effect, so that the pipeline is not buried in a thermal pipe network.

The technical scheme for realizing the first purpose of the invention is as follows: the novel municipal road pipe network is provided with a pipe chase and a pipeline laid in the pipe chase; and geopolymer foamed concrete is filled and poured in the pipeline groove.
A plurality of supporting blocks for supporting the pipeline are arranged in the pipeline groove along the extending direction.
As an optimized design, the pipeline groove is arranged adjacent to the green belt; the geopolymer foam concrete in the pipeline groove is in direct contact with the green belt.
The supporting block is a geopolymer foamed concrete prefabricated part.

The second purpose of the invention is to provide a construction process of the novel municipal pipeline network.
The technical scheme for realizing the second purpose of the invention is as follows: the construction process for laying the novel municipal pipeline network comprises the following steps;
s1, digging a pipeline groove and a backfill groove of a green belt;
s2, laying pipelines in the pipeline grooves;
s3, pouring geopolymer foam concrete into the pipeline groove; meanwhile, paving a cushion layer on the foundation of the green belt, and then pouring a geopolymer foam concrete layer on the cushion layer;
and S4, filling soil in the backfill groove to form a fill layer.
The invention has the positive effects that: (1) the geopolymer foamed concrete can effectively support and wrap the pipeline, and is not easy to damage the pipeline; meanwhile, the protective effect on pipelines is good.
(2) The geopolymer foamed concrete can effectively remove the seepage water, and avoids the problems of aging and corrosion of pipelines in a humid environment for a long time.
(3) The invention effectively combines the pipeline groove with the green belt, guides the seepage water to the green belt through the geopolymer foamed concrete and provides a water source for the green belt.
(4) In the geopolymer foam concrete, a microstructure channel is formed inside the geopolymer foam concrete by the bubbles, and the microstructure channel can play double effects of water permeation and water storage; the microstructure channel is not easy to be blocked by fine particles, so that the long-term stable water permeation effect of the microstructure channel can be ensured; the microstructure channel also has certain water storage performance, and the water can volatilize to the filling layer of the green belt through evaporation, so that the water is provided for green plants
