Problems solved by technology

During the backfilling process, due to stones or other sharp objects in the backfill soil, it often causes damage to the pipeline, resulting in cracking and damage to the pipeline
Traditionally buried pipelines have always been unsatisfactory in terms of thermal insulation, so the heat pipe network is often not buried

Embodiment 1

[0029] See figure 1 , the new municipal pipeline network in the present invention has a pipeline trough 1 and a pipeline 2 laid in the pipeline trough 1; a plurality of support blocks 3 for supporting the pipeline 2 are arranged in the pipeline trough 1 along its extending direction; The pipeline groove 1 is filled with geopolymer foamed concrete 4 .

[0030] The support block 3 is a geopolymer foamed concrete prefabricated part.

[0031] The construction technique for laying the above-mentioned novel municipal pipeline network of the present invention comprises the following steps;

[0032] S1, digging the pipeline groove 1;

[0033] S2, laying the pipeline 2 in the pipeline groove 1;

[0034] S3, pouring the geopolymer foam concrete 4 to fill the pipeline trench 1 .

[0035] The components of the geopolymer foam concrete 4 are as follows by mass percentage:

[0036] Steel slag powder: 45%, modified red mud: 5%; modified metakaolin: 25%; class I fly ash: 16.18%; coagulan...

Embodiment 2

[0038] See figure 2 with image 3 In the present invention, the new municipal pipeline network has a pipeline trough 1, and the pipeline trough 1 is adjacent to the green belt 5, and a plurality of support blocks 3 for supporting the pipeline 2 are arranged in the pipeline trough 1 along its extension direction, and the pipeline 2 It is arranged in the pipeline trough 1; the pipeline trough 1 is filled with geopolymer foamed concrete 4.

[0039] The support block 3 is a geopolymer foamed concrete prefabricated part.

[0040] The green belt 5 includes a foundation 6, a cushion layer 7, a geopolymer foam concrete layer 8 and a filling layer 9 from bottom to top.

[0041] The cushion layer 7 is a gravel pavement layer.

[0042] The geopolymer foamed concrete layer 8 of the green belt 5 is lower than the bottom surface of the pipeline trough 1 . The geopolymer foam concrete 4 in the pipeline channel 1 is in direct contact with the filling soil layer 9 of the green belt 5 .

Abstract

The invention relates to a novel municipal road pipe network and a construction process. The novel municipal road pipe network is provided with a pipeline groove and pipelines laid in the pipeline groove; and the pipeline groove is filled with and poured with geopolymer foaming concrete. According to the novel municipal road pipe network and the construction process, the geopolymer foaming concrete is used as filler, so that can not only the pipelines is protected from deformation and cracking, but also the certain heat preservation effect on the pipelines is realized; and at the same time, the self water permeability of the geopolymer foaming concrete is used, so that accumulative water in the periphery of the pipelines is quickly removed.

Description

technical field [0001] The invention relates to a novel municipal road pipe network and construction technology. Background technique [0002] The municipal pipe network is an important infrastructure and the lifeblood of a city. The municipal pipe network generally includes electricity, telecommunications, network, communication, heat, gas, rainwater drainage and sewage drainage, etc. In order to ensure the normal operation of the municipal pipe network, not only the construction of the pipe network must be standardized, but also the daily maintenance of the pipe network must be done well. [0003] For the pipe network buried on municipal roads, during construction, it is generally necessary to excavate the pipeline trench first, then install the pipeline in the pipeline trench, and then bury the pipeline in the pipeline trench by backfilling. During the backfilling process, due to stones or other sharp objects in the backfill soil, the pipeline is often damaged, resultin...
