Abstract
The utility model relates to a protective rail type low temperature heating stick. The condensing segment of a low temperature heating stick arranged in a frozen soil roadbed baring the ground is bent in a horizontal direction to become a heterotype heating stick of about five to fifteen degrees with a horizontal included angle. The end part of the bent part of the low temperature heating stick corresponding to a height and the height of a protective rail is connected with an adjacent low temperature heating stick through a connecting piece. The heating stick of the utility model still exerts due functions, and drivers' visual fatigue is also eliminated. One object can also have multiple uses at the same time, and a common protective rail is replaced. In this way, the composite cost of a project is reduced and installed project quantity is decreased. At the same time, vehicles taking place accidents can be prevented from rushing at an opposite passage or the roadbed so as to lighten personal casualties and property loss.
Description
Technical field the utility model relates to a kind of heat pipe, especially for the hot pin in high alpine frost soil area.
Background technology is present, for solving the stable problem of permafrost area embankment, people bury hot pin underground in roadbed, as road both sides in Qinghai-Tibet Railway and Qinghai-Tibet Highway part highway section, spacing 3-4 rice, length overall have been installed is 8-12 rice, the length of basseting is the low temperature hot-bar of 3-4 rice, is used to keep the stable of roadbed.Though these low temperature hot-bars can protect roadbed indeformable effectively; but also there is certain weak point; because the height that low temperature hot-bar bassets is higher than people's horizontal line of sight far away; if the speed of a motor vehicle is pressed 100-120 kilometer/hour calculating; then the time through adjacent two hot pins is 1/5-1/9 second; and people's the vision time of staying is 1/12-1/16 second, so head driver time steering vehicle under this condition easily causes visual fatigue, causes security incident to take place.
The summary of the invention the purpose of this utility model is to provide a kind of can keep the stable protection bar low temperature hot-bar that can eliminate visual fatigue effectively again and have the security protection effect concurrently of frozen soil.The utility model mainly is that the condensation segment that low temperature hot-bar bassets bends to level, and its end is connected to an integral body with adjacent low temperature hot-bar again.The utility model mainly includes low temperature hot-bar and connector, and wherein low temperature hot-bar is and is used for frozen earth roadbed hot pin, and its structure can have multiple, is many arms etc. as straight tube, condensation segment.The condensation segment that low temperature hot-bar bassets bends to horizontal direction, becomes the special-shaped rod about 5 °-15 ° with horizontal plane angle, and the end distance ground level that hot pin is exposed is higher than the height of bending part apart from ground, and the liquid phase heat-transfer working medium that is beneficial in the hot pin refluxes.The height of above-mentioned hot pin crooked position is corresponding with guardrail height, and the end of this hot pin sweep is connected to become a whole by connector and adjacent hot pin, and parallel with road direction.
The utility model has following advantage compared to existing technology:
1. hot pin of the present utility model is that profile changes to some extent, therefore still brings into play its due effect, promptly keeps frozen earth roadbed stablizing.
2. the change of hot pin external form in the utility model is highly reduced to below the horizontal line of sight it, has eliminated driver's visual fatigue, has avoided the security incident that causes thus.
3. the hot pin that holds together in the utility model also has function of safety protection, one-object-many-purposes, can replace common protective guard fully, the integrated cost of engineering, the engineering quantity that minimizing is installed have so not only been reduced, the vehicle that simultaneously can avoid again having an accident rushes at anti-road or rushes at roadbed, to alleviate casualties and property loss.
Description of drawings
Accompanying drawing 1 is the user mode schematic diagram of the utility model example 1
Accompanying drawing 2 is user mode schematic diagrames of the utility model example 2
The specific embodiment is in the user mode signal of protection bar low temperature hot-bar shown in Figure 1
Among the figure, the evaporator section 2 of low temperature hot-bar 1 is located in frozen earth roadbed 3, length of embedment is the thickness of frozen earth layer upper limit below 4, and the straight pipe type condensation segment that this low temperature hot-bar has a heat exchange fin bassets and to the horizontal direction bending, and becoming with horizontal plane angle is 5 °-15 ° L shaped rod.
This height and the corresponding low temperature hot-bar sweep of guardrail height, its end links to each other with adjacent low temperature hot-bar by connector 5.In the user mode schematic diagram of protection bar low temperature hot-bar shown in Figure 2, its structure and example 1 are basic identical, the cast condensation segment that this low temperature hot-bar has heat exchange fin bassets, and they are respectively to the horizontal direction bending, becomes to be about 5 °-15 ° T shape rod with horizontal plane angle.This height and the corresponding low temperature hot-bar sweep of guardrail height, two end link to each other with the end of adjacent low temperature hot-bar sweep by connector respectively.
Claims (1)
1. one kind is protected the bar low temperature hot-bar, it is characterized in that: be located at the condensation segment that the low temperature hot-bar in frozen earth roadbed bassets and bend to horizontal direction, become the special-shaped hot pin about 5 °-15 ° with horizontal sextant angle, this height and the corresponding low temperature hot-bar sweep of guardrail height, its end links to each other with adjacent low temperature hot-bar by connector.
