Problems solved by technology

[0005] The purpose of the present invention is to solve the problems of high labor intensity, low efficiency and poor safety when laying the water supply pipeline in the electrified section of the railway station in the prior art, which cannot be constructed by open-cut method, and by manual excavation Provides a construction method for laying pipelines in the electrification section of railway stations. The construction method adopts a drilling rig to excavate the pipeline holes, and at the same time uses the drilling rig equipment to back-drag the pipelines to fill the pipeline holes, thereby completing the pipeline laying work of the water supply system and solving the problem of The problem of inability to excavate in the existing technology avoids the problems of high labor intensity, low efficiency and poor safety in manual excavation, and greatly improves the construction efficiency

Embodiment 1

[0072] Such as figure 1 with figure 2 As shown, the construction method of pipe laying in the electrified section of the railway station yard includes the following steps:

[0073] a. Measure and pay off;

[0074] b. Layout site, including equipment site 1 and pipeline site 2 at both ends of railway line 6;

[0075] c. Excavation, excavation of working pits and return pipe trench 21, working pits including entrance working pit 11 and unearthed working pit 22;

[0076] d. To excavate the pipe hole, use the method of overall directional crossing to excavate the pipe hole,

[0077] e. Lay the pipeline, connect the pipeline to be laid with the tunneling equipment at the excavation point, and drag the pipeline back to complete the laying.

[0078] In this embodiment, an old station is taken as an example for description. The station includes multiple lines, the catenary above the line has also been connected to the network for power transmission, and some lines are still used for transportat...

Embodiment 2

[0112] In this embodiment, the installation of the upper water well is carried out on the basis of the pipeline laying in embodiment 1. Step e specifically includes the following steps:

[0113] f1. Excavation, excavate the well to a predetermined depth;

[0114] f2. Lay cushion under the well site pipeline;

[0115] f3. Masonry well chamber, install prefabricated shaft;

[0116] f4. Install water supply and drainage pipes;

[0117] f5. Pipeline test. Tightness test for water supply pipeline, using water pressure test or air pressure test.

[0118] In step f1, when the well site is excavated, due to the intricacies of underground cables, optical cables, and existing pipelines, it needs to be confirmed in advance, using the previously constructed underground cables, optical cables and existing pipelines, and at the same time organize the operators according to the standard Dig and set up trenches for the pipeline vertically and horizontally, find construction obstacles and let the proper...

Abstract

The invention relates to the technical field of railway station construction, in particular to a construction method for laying pipelines in electrified sections of railway stations, including: a) measuring and setting out lines; b) arranging equipment sites and pipeline sites; c) excavating work pits and returning pipe ditch; d) the overall directional crossing of the excavation pipe hole; e) the laying of the back-towing pipe is completed, and the laying of the water supply system pipe is completed through this construction method, which solves the problem that existing technology cannot be cut open and avoids the use of The problems of high labor intensity, low efficiency and poor safety in manual excavation have greatly improved the construction efficiency. The invention greatly reduces the construction cost of the pipeline laying in the electrified section of the railway station, shortens the construction period, and solves the problems in the existing The technical problems in the construction of railway stations on the line have good promotion and application value.

Description

Technical field [0001] The invention relates to the technical field of railway station yard construction, in particular to a construction method for laying pipelines in an electrified section of a railway station yard. Background technique [0002] With the continuous development of my country’s infrastructure construction, existing old stations often need to be expanded or renovated. During the construction of railway yards, train water supply systems need to be arranged to maintain the water supply function and water supply system of passenger trains at the station. During the construction process, the most important link and construction task is to lay water pipelines and arrange water wells. [0003] Due to the influence of the existing facilities in the railway station yard, it is impossible to use the open-cut method to complete the pipeline laying. On the one hand, due to the construction of many buildings on the ground of the railway yard, open-cut excavation is not possible...
