Example Embodiment

[0028] (Example 1)

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

[0030] The supporting block 3 is a geopolymer foamed concrete preform.

[0031] The construction process of laying the above-mentioned new municipal pipeline network of the present invention includes the following steps;

[0032] S1, pipeline trench 1;

[0033] S2, laying pipeline 2 in pipeline tank 1;

[0034] S3. Pour the geopolymer foam concrete 4 to fill the pipeline trough 1.

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

[0036] Steel slag powder: 45%, modified red mud: 5%; modified metakaolin: 25%; grade I fly ash: 16.18%; coagulant: 4%; red mud with liquid: 3.62%; f...

Example

[0037] (Implementation 2)

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

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

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

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

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