Problems solved by technology

At present, the power supply of coal mines often uses overhead lines on the ground, but the erection lines are long and require irregular maintenance and repairs, requiring many workers, heavy cable loads, heavy maintenance and repairs, high labor intensity, and long construction periods. , high maintenance costs and other unfavorable factors
And the cable is exposed to the outside world for a long time, and it is also easy to be damaged or damaged.

Embodiment 1

[0036] In this embodiment, a cable laying method for vertically laying pipelines includes the following steps:

[0037]Step 1: Positioning and construction of the laying pipeline, the upper part of the laying pipeline is located in the area of ​​electrical equipment 10m, the lower part communicates with the transportation avenue 2, and the laying pipeline is perpendicular to the transportation avenue 2; construct and lay the pipeline through the secondary hole forming method; 1) Construct the upper pipeline 3 (0-466m section), drill a large hole 1 (25-50cm) with a drilling rig, lift and weld several adjacent short seamless steel pipes (pipe wall thickness 12mm) in the large hole 1 Lower into the large hole 1, and form an annular gap 5 with a thickness of 5 cm between the inner wall of the large hole 1 and the upper pipe 3; 2) Inject the slurry in the annular gap 5 from the bottom of the upper pipe 3 to the ground; 3 ) After the grout is fixed, build the lower pipeline 4 (460-4...

Embodiment 2

[0046] In this embodiment, a cable laying method for vertically laying pipelines includes the following steps:

[0047] Step 1: Positioning and construction of the laying pipeline, the upper part of the laying pipeline is located in the area of ​​electrical equipment 18m, the lower part communicates with the transportation avenue 2, and the laying pipeline is perpendicular to the transportation avenue 2; construct and lay the pipeline through the secondary hole forming method; 1) Construct the upper pipeline 3 (0-455m section), drill a large hole 1 (25-50cm) with a drilling rig, lift and weld several adjacent seamless steel short pipes (pipe wall thickness 8mm) in the large hole 1 Lower into the large hole 1, and an annular gap 5 with a thickness of 8 cm is formed between the inner wall of the large hole 1 and the upper pipe 3. In the annular gap 5, the slurry is injected in reverse from the bottom of the upper pipe 3 to the ground; 3) Wait for the slurry After fixing, build t...

Abstract

The invention provides a cable laying method for vertically laying pipelines. The method comprises the following steps: 1. Positioning and construction of laying pipelines; 2, build an operation platform and laying equipment on that upper part of the laying pipeline; 3, laying cables; Step 4: Fixing cables. step 4, fixing a plurality of auxiliary wire rope are fixed on that upper part of a main wire rope, the auxiliary wire rope is used for supporting the main wire rope, and the ends of the auxiliary wire rope are suspend and fixed on both ends of the load-bearing crossbar on the upper part ofthe laying pipe. The utility model has the advantages of relatively safe coal mine power supply, low cost and convenient maintenance. The great innovation of power supply mode is of great significance for popularization. The service life of the cable is prolonged.

Description

technical field [0001] The invention relates to the field of cable laying, in particular to a cable laying method for vertically laying pipelines. Background technique [0002] Cable laying refers to the installation method of connecting cables from one place to another. The choice of cable laying method should be considered according to engineering conditions, environmental characteristics, cable type, quantity and other factors, and construction costs. [0003] Existing cable laying generally includes cable trenches, cable tunnels, ground overhead, buried and other methods. Due to the difference in topography, cable trenches, cable tunnels, and embedding are not suitable for coal mines. At present, the power supply of coal mines often uses overhead lines on the ground, but the erected lines are relatively long, requiring irregular maintenance and repairs, requiring many workers, heavy cable loads, heavy maintenance and repairs, high labor intensity, and long construction ...
