Installation and construction method for high-altitude pipeline in circular-section tunnel

Abstract

The invention relates to a construction method for mechanical and electrical installation engineering in a circular-section tunnel, in particular to a construction method for installing a high-altitude pipeline in the circular-section tunnel, which comprises the following steps of construction preparation, rail-mounted folding tool manufacturing, prefabrication, bracket installation, pipeline installation, wire laying, lamp installation, cable laying and system debugging. The rail-mounted folding tool is designed according to the circular tunnel section form, the folding tool is efficient and convenient, a conventional circular curved surface structure high-altitude construction technology is replaced, and the construction cost is reduced. According to the folding tool, the triangular stability is applied, the stabilizing frame is connected with the operation platform and the climbing device to form a triangular structure, the overall stability is improved, the structural safety is guaranteed, an inner and outer ring structure is manufactured according to the sliding bearing principle, and the pipeline is rotated to be folded through the folding tool; according to the principle of acting force and counter-acting force, the limiting anti-derailment brake rod is manufactured, personnel conduct construction on an operation platform, and the bottom of the limiting anti-derailment brake rod makes close contact with the waist outside a steel rail to achieve the braking effect.

Description

technical field [0001] The invention relates to a construction method for electromechanical installation engineering in a circular section tunnel, in particular to a construction method for high-altitude pipeline installation in a circular section tunnel. Background technique [0002] With the development of the economy, more and more subway projects are being repaired, among which the electromechanical installation projects in the tunnels are becoming more and more complicated, and the construction difficulty is becoming more and more difficult. The tunnel installation project mainly includes tunnel lighting, tunnel fire fighting pipelines, tunnel cable laying and tunnel maintenance equipment installation, etc. Among them, tunnel lighting and tunnel cables are required to be laid in the middle and upper parts, and personnel need to rely on the frame to carry out the work. So how to set up the frame body of the circular structure and what kind of frame body can move quickly ...
