Problems solved by technology

[0002] At present, domestic highway pipelines are basically laid out in pre-buried or overhead ways. Each department performs its own duties, forming superficially clear responsibilities, but in fact they cannot be coordinated and unified, causing various confusions and inconsistencies. After digging here today, the day after tomorrow Dig up there and cause a lot of damage and waste

Embodiment 1

[0032] A construction method for a municipal comprehensive pipeline channel, comprising the following method steps:

[0033] Step 1: Locate the coordinates and direction of the pipeline according to the requirements of the construction drawing of the pipeline design, and perform piling and laying out to determine the position, width and depth of the trench;

[0034] Step 2: Use mechanical grooving for piling and laying out. If there is a pipeline below, use manual grooving near the pipeline;

[0035] Step 3: Tamp and level the groove, and lay a waterproof cement mortar bonding layer;

[0036] Step 4: On the basis of protecting the anti-corrosion layer of the pipe body and not damaging the concrete, the personnel will use the high-strength nylon belt to hoist the prepared prefabricated U-shaped pipe for mechanical lowering;

[0037] Step 5: Appropriately add sand bags to both sides of the assembled U-shaped prefabricated pipeline placed below to stabilize the assembled U-shape...

Abstract

The invention discloses a construction method of a municipal comprehensive pipeline passage. The construction method is characterized by comprising the following steps: 1, according to the requirementof a pipeline design construction drawing, positioning the coordinates and trend of the pipeline, and piling and paying off to determine the position, width and depth of a groove; 2, adopting mechanical channeling at the piling and paying-off parts, and if the pipeline exists underground, adopting manual channel near the pipeline; 3, tamping, levelling and treating the groove, and paving a waterproof cement mortar bonding layer; 4, on the basis of protecting a pipe body anticorrosive layer and not destroying concrete, adopting a high-strength nylon tape to hoist a prepared fabricated U shapedprefabricated pipeline to mechanically lower the pipeline; and 5, properly putting sand bags on the two sides of the lowered fabricated U shaped prefabricated pipeline to fix so as to stabilize the fabricated U shaped prefabricated pipeline. The construction method adopts centralized large-scale arrangement to effectively solve the problem about disordered pipelines in a town.

Description

technical field [0001] The invention belongs to the technical field of construction methods, and in particular relates to a construction method for municipal comprehensive pipeline channels. Background technique [0002] At present, domestic highway pipelines are basically laid out in pre-buried or overhead ways. Each department performs its own duties, forming superficially clear responsibilities, but in fact they cannot be coordinated and unified, causing various confusions and inconsistencies. After digging here today, the day after tomorrow Dig there and cause a lot of damage and waste. Therefore, the present invention is proposed. Contents of the invention [0003] The purpose of the present invention is to provide a construction method of municipal comprehensive pipeline channel to solve the problems raised in the above-mentioned background technology. [0004] In order to achieve the above object, the present invention provides the following technical solutions: a...
