Abstract
The utility model relates to a complex hot bar to keep frozen soil stable, which comprises a hot bar. The utility model is characterized in that in the pipe of the heat-absorbing section of the discharged hot bar is inserted with another small diameter hot bar, the outer diameter of which is smaller than the inner diameter of the pipe of the discharged hot bar, wherein packing filling is provided between the two hot bars. Compared with prior technology, the utility model has the advantages that replacing of the hot bars for keeping frozen soil stable is simple, the construction of the replacing is convenient, manual power and materials are saved, and the roadbed will not be damaged. Besides the heat absorbing section of the bottom of the hot bar is designed as a complex, which reinforces the anti-corrosion property of the small diameter hot bar.
Description
Technical field the utility model relates to a kind of heat pipe, especially for keeping the stable hot pin of frozen soil.
The hot pin that background technology is made up of heat pipe, fin, hoisting mechanism and anticorrosive coat, it in use owing to reasons such as inner pneumatosis, leakage, corrosion, causes hot pin that arranged certain application life.When hot pin exceeds service life and after losing efficacy, need change hot pin.Yet it is very difficult that the hot pin that uses on frozen soil is changed, and needs the used heat rod is taken out from frozen soil, and then inserts a new hot pin.Because hot pin self is longer, be again to be inserted in the frozen soil, not only constructional difficulties will expend a large amount of man power and materials, but also damages the roadbed etc. at its place easily.
The summary of the invention the purpose of this utility model is to provide a kind of replacing to keep the stable complex hot pin of frozen soil easily.The utility model mainly includes: hot pin, used heat rod endotherm section body and filler.Wherein the used heat rod is that tube wall is corroded and penetrates, and can not pour into the hot pin of heat-conducting work medium more again.Clip the radiating segment that this hot pin is exposed at the face of land, the body of staying the interior lower end closed of soil layer (comprising ground) is a used heat rod endotherm section body.In above-mentioned body interpolation an external diameter another root minor diameter hot pin less than used heat rod internal diameter of tube body is arranged.So used heat rod endotherm section body is wrapped in the endotherm section body outside of minor diameter hot pin, makes endotherm section become complex.And be provided with filler between minor diameter hot pin and both endotherm sections of used heat rod, to prevent normally carrying out of the heat insulation influence heat transfer of air.Above-mentioned minor diameter hot pin also is to be used to the hot pin that keeps frozen soil stable, and it includes essential parts such as heat pipe, fin, hoisting mechanism and anticorrosive coat, but profile can design as required, and it can be identical with former hot pin, also can be different.The utility model has following advantage compared to existing technology:
1. be used in and keep the stable hot pin of frozen soil to change simple, easy construction, use manpower and material resources sparingly, can not damage roadbed etc. again simultaneously.
2. the endotherm section of hot pin bottom is a complex, has strengthened the resistance to corrosion of minor diameter hot pin.
Description of drawings
Fig. 1 is that schematic diagram cuts open in the utility model user mode master office of looking.
The specific embodiment is cutd open in the schematic diagram in the user mode master office of looking of the stable complex hot pin of maintenance frozen soil shown in Figure 1, stay the used heat rod endotherm section body 3 in soil layer 1 and the ground 2, be inserted with an external diameter another root minor diameter hot pin 4 in it, be provided with filler layer 5 between the two less than used heat rod internal diameter of tube body.Above-mentioned minor diameter hot pin includes heat pipe, fin, anticorrosive coat and hoisting and locating mechanism.
Claims (1)
1. one kind keeps the stable complex hot pin of frozen soil, and it includes hot pin, it is characterized in that: be inserted with the minor diameter hot pin of another root external diameter less than used heat rod internal diameter of tube body in used heat rod endotherm section body, be provided with filler between the two.
