Embodiment 1

[0061] It is suitable for pre-embedded pipelines in shallow pavement, which includes a pavement pre-embedded groove 1, and a base layer 2 is arranged in the pavement pre-embedded groove 1, and its difference lies in that a pipeline reinforcement component is arranged on the base layer 2 3. Support channels 4 are distributed in the pipeline reinforcement component 3 . In this way, multiple groups of pipelines distributed in the same direction can be laid and protected. Considering the bearing capacity of the support channel 4 for longitudinal stress, the support channel 4 is provided with auxiliary support rods 5, and the upper and lower ends of the auxiliary support rods 5 are aligned with the support channel. 4 The inner walls are in contact.

[0062] A partition assembly 6 is distributed on the periphery of the support channel 4, which can effectively partition the downward water seepage from the surface of the road surface. Thus, an airtight protective space is formed betw...

Embodiment 2

[0074] The pre-embedded pipeline suitable for the shallow layer of the pavement includes a pavement pre-embedded groove 1, and a base layer 2 is arranged in the pavement pre-embedded groove 1. The difference between it and the prior art is that: There is a pipeline reinforcement component 3, and support channels 4 are distributed in the pipeline reinforcement component 3. In this way, multiple groups of pipelines distributed in the same direction can be laid and protected. Considering the bearing capacity of the support channel 4 for longitudinal stress, the support channel 4 is provided with auxiliary support rods 5, and the upper and lower ends of the auxiliary support rods 5 are aligned with the support channel. 4 The inner walls are in contact.

Embodiment 3

[0087] It is suitable for pre-embedded pipelines in shallow pavement, which includes a pavement pre-embedded groove 1, and a base layer 2 is arranged in the pavement pre-embedded groove 1. Supporting channels 4 are distributed in the reinforcement assembly 3 . Meanwhile, an auxiliary support rod 5 is arranged in the support channel 4 , and the upper and lower ends of the auxiliary support rod 5 are in contact with the inner wall of the support channel 4 . In order to effectively block the downward water seepage of the pavement surface, a partition assembly 6 is distributed around the support channel 4 . Thus, an airtight protective space is formed between the partition assembly 6 and the periphery of the support channel 4 . At the same time, a filling layer 7 is arranged in the protection space. Moreover, in the present invention, a backfill layer 8 is distributed in the pavement embedded groove 1, and a barrier layer 9 is laid on the backfill layer 8.

Abstract

The invention relates to a pre-buried pipeline suitable for pavement shallow layers. The pre-buried pipeline comprises a pavement pre-buried groove, wherein a foundation layer is arranged in the pavement pre-buried groove. The pre-buried pipeline is characterized in that a pipeline strengthening assembly is arranged on the foundation layer; supporting channels are distributed in the pipeline strengthening assembly; auxiliary supporting rods are arranged in each of the supporting channels; besides, partition assemblies are distributed at the periphery of each of the supporting channels; a filling layer is arranged between the partition assemblies and the periphery of each of the supporting channels; a back-filling layer is distributed in the pavement pre-buried groove, and a blocking layer is distributed on the back-filling layer. Therefore, the laying requirement of multiple pipelines is met, and besides, the pre-buried pipeline can effectively bear external stress, so that an internal pipeline can be protected from being stricken, and underground water can be prevented from permeating into the pipeline and eroding the pipeline; in addition, the pipeline can bear downward longitudinal stress from the ground, so that the longitudinal extrusion for a subsequent pipeline is avoided.

Description

technical field [0001] The invention relates to a pre-buried pipeline, in particular to a pre-buried pipeline suitable for shallow pavement. Background technique [0002] As far as the existing municipal engineering (municipal engineering) is concerned, it refers to the construction of municipal facilities. In my country, municipal facilities refer to various buildings, structures, equipment, etc. that are set up within the planning and construction scope of urban areas, towns (townships), and provide residents with paid or unpaid public products and services based on government responsibilities and obligations. At the same time, the construction of various public infrastructure supporting urban life belongs to the category of municipal engineering, such as common urban roads, bridges, subways, and various pipelines closely related to life: rainwater, sewage, water supply, reclaimed water, electricity ( The part outside the red line), telecommunications, heat, gas, etc., as...
