Embodiment Construction

[0028] The application will be described in further detail below in conjunction with the accompanying drawings. It is necessary to point out that the following specific embodiments are only used to further illustrate the application, and cannot be interpreted as limiting the protection scope of the application. The above application content makes some non-essential improvements and adjustments to this application.

[0029] Such as figure 1 As shown, the tunnel drainage and antifreeze integrated system in the severe cold area is composed of active insulation system and passive insulation system.

[0030] Among them, the active insulation system includes a heat source supply device 1, a heat source circulation pipeline 2, a heat collection device 3, a water replenishment pipeline 4, a heating circulation pipeline 5 and a heating pipeline 6. The device 3 is connected to provide a heat source for the heat collecting device 3, one end of the replenishment pipeline 4 is connected t...

Abstract

The invention discloses a tunnel drainage anti-freezing integrated system in alpine and severe cold regions, which comprises an active insulation system and a passive insulation system, wherein the active insulation system includes a heat source supply device, a heat source circulation pipeline, a heat collection device, a water supplement pipeline, a heating circulation pipeline and a heating pipe; the passive insulation system includes a central drainage pipe anti-freezing layer arranged surround the tunnel central drainage pipe, a side channel anti-freezing layer arranged surround the tunnel side channel, and a blind pipe anti-freezing layer arranged at the outer sides of the tunnel circumferential blind pipe and vertical blind pipe. The tunnel drainage anti-freezing integrated system in the alpine and severe cold regions has the advantages that the heat demand is satisfied, which is needed for ensuring smooth water flow without ice of the tunnel drainage system in the regions withmonthly average temperature of -15 DEG C; in addition, an inorganic nanometre vacuum insulation plate is added as the passive insulation measure, which can effectively solve the problem of anti-freezing tunnel drainage system in the alpine and severe cold regions. Besides, the overall system has the advantages of small construction area, convenient construction, low cost, environmental protectionand high efficiency, and strong stability of structure and function and the like.

Description

technical field [0001] The invention relates to the technical field of tunnel drainage heat preservation and antifreeze, in particular to an integrated system for tunnel drainage and antifreeze in high and severe cold regions. Background technique [0002] The rapid development of my country's railways began to develop in the northwest, southwest, northeast and other underdeveloped regions under the condition that the development of the developed regions in the central and eastern regions was basically mature. Northwest and Northeast are severe cold regions, the average temperature of the coldest month in most regions is lower than -10°C, and there are a large number of seasonal frozen soils for 3-6 months in many regions. The construction of railway tunnels in such severe cold areas has extremely high requirements for waterproofing, drainage and heat preservation. Otherwise, the water flow in the tunnel and the accumulated water in the surrounding rocks will freeze, which w...
