Embodiment Construction

[0022] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0023] Such as figure 1 As shown, in the present embodiment, the construction method of concrete-encapsulated lightweight pipelines includes the following steps: 1. When pouring the concrete layer at the bottom of the lightweight pipelines, a certain amount of water is pre-embedded on both sides of the installation position of the lightweight pipelines. The length of the L-shaped steel bar, the upper end of the steel bar is exposed to a certain height on the surface of the concrete layer, such as exposed 100mm-200 mm; the lower end of the L-shaped steel bar is arranged in the concrete layer, or connected to the steel bar of the concrete layer, such as Bind it by welding (spot welding) or small steel wire or tie wire; or simply hook it on the ste...

Abstract

The invention discloses a construction method of a concrete packing light pipeline. The construction method comprises the steps of: correspondingly embedding a plurality of L-shaped steel bars with a certain length at each of the two sides of the light pipeline mounting position, wherein the upper ends of the steel bars are exposed out of the surface of a concrete layer by a certain height; mounting a light pipeline between two rows of L-shaped steel bars; arranging packing strips on the light pipeline, wherein the two ends of the packing strips are respectively connected to the two L-shaped steel bars corresponding to the two sides of the light pipeline and the packing strips press on the outer surface of the light pipeline; and casting the concrete layers on the left and right side surfaces and the top of the light pipeline to form the structure of the concrete packing light pipeline meeting technical requirements. By adopting the construction method, the upward floatation of the light pipeline can be effectively prevented, the translocation of the light pipeline is prevented, construction quality reaches design requirement, and the quality problem formed by the upward floatation of the light pipeline is eradicated completely; and the construction method is simple and reliable, spot operation is convenient, and operators can easily master the construction method.

Description

technical field [0001] The invention relates to a construction method for a building pipe network, in particular to a construction method for concrete-encapsulated lightweight pipes in municipal pipe network construction. [0002] Background technique [0003] In the construction of municipal pipe network, it usually involves the laying and installation of pipe network, (especially in the installation of cross-street pipe network), such as the installation and construction of rainwater sewers, sewage sewers and other pipes; many projects, especially in the trend of new technology innovation Under the condition that the strength of the pipe material is generally constant, the material is getting lighter and lighter. In terms of design, it is required to encapsulate all kinds of light pipe networks with concrete, that is, plastic pipes, rubber pipes or other synthetic materials with low density. The pipeline (PVC, etc.) is laid in concrete, and the concrete is wrapped around ...
