Embodiment 1

[0032] Such as Figure 1-3 As shown, a thermal insulation culvert pipe system between lines in a railway station includes a thermal insulation culvert pipe 1 and a protective culvert pipe 2. The thermal insulation culvert pipe 1 is buried below two adjacent existing lines 01 and is parallel to the existing line 01. The protective culvert pipe 2 spans A number of existing lines 01 are buried below. One end of the insulation culvert pipe 1 is vertically connected to the protection culvert pipe 2, and the other end of the insulation culvert pipe 1 is connected to the water supply platform 03; The heating pipeline 5, wherein the water supply pipeline 3 and the drainage pipeline 4 are connected to the municipal pipe network, and the heating pipeline 5 includes two pipelines, one supply and one outlet, and are connected to the boiler room. For example, the heating pipeline 5 adopts two 108*4 seamless steel pipes, The heating pipe 5 provides the water supply pipe 3 with the temperatu...

Embodiment 2

[0037] The present invention also discloses a construction method for burying the thermal insulation culvert pipe system between lines in railway stations, including the above-mentioned thermal insulation culvert pipe system for line parts in railway stations, including the following construction steps:

[0038] Step 1. Erect D-shaped beams, protect the excavation site, and lift the existing line 01 in the installation area through D-shaped beams;

[0039] Step 2, protect the culvert pipe 2 jacking, such as Figure 4 As shown, excavate the working pit 10, pour a C15 concrete cushion with a thickness not less than 100mm at the bottom of the working pit 10, lay the jacking guide rail 9 in the working pit 10, place the protective culvert pipe 2 on the jacking guide rail 9, and use two hydraulic The jack is jacked in one direction until the jacking of the protective culvert pipe 2 is completed;

[0040] Among them, when the protection culvert pipe 2 is jacked, the internal expans...

Abstract

The invention discloses a heat insulation culvert pipe system between internal lines in a railway station and a burial and construction method. The heat insulation culvert pipe system comprises a heat insulation culvert pipe and a protective culvert pipe. The heat insulation culvert pipe is buried below two adjacent existing lines. The protective culvert pipe stretches over the existing lines and is buried below the existing lines. One end of the heat insulation culvert pipe is connected with the protective culvert pipe. The other end of the heat insulation culvert pipe is connected with a platform to which water is to be supplied. The heat insulation culvert pipe and the protective culvert pipe are internally provided with a water supply pipeline, a drainage pipeline and heat supply pipelines. The burial and construction method comprises the steps of erection of a D-shaped beam, jacking construction of the protective culvert pipe, excavation of a pipe ditch between the existing lines, installation of the heat insulation culvert pipe, installation of the water supply pipeline, the drainage pipeline and the heat supply pipelines and burial completion. According to the heat insulation culvert pipe system, the heat insulation culvert pipe and the protective culvert pipe are laid below the existing lines, supplied water is successfully led into the platform to which the water is to be supplied, the water supplement capacity to passenger trains can be enhanced, input of manpower, materials and equipment is reduced, and it is guaranteed that railway transport is fast and unobstructed; by means of the construction method, the construction period is shortened, the working efficiency is improved, and safety and reliability are achieved.

Description

technical field [0001] The invention relates to the field of pipeline engineering construction, in particular to a thermal insulation culvert pipe system and buried construction method between lines in railway stations. Background technique [0002] For areas with cold regions and low temperatures, when the water supply system of busy railway stations cannot solve the problem of insufficient water supply for passenger cars, it is necessary to solve the problem of ensuring the normal water supply of passenger trains without delaying the railway transportation time, and at the same time solve the technology of keeping the water pipes warm problem, and the existing manual external water addition is not only labor-intensive and delays a lot of railway transportation time, but also the tap water cannot be kept warm. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned shortcomings of high labor intensity, low water replenish...
