Description

The rock-steady structure of plateau structure foundation

Technical field the utility model relates to a kind of base stabilization structure, especially the rock-steady structure of structure foundation under plateau permafrost environment.

The ground of some high original buildings of background technology is based upon on frozen soil.At geothermal energy resources, than more rich place, the rising of underground heat is subject to stopping of structure foundation and is trapped in the frozen soil below ground, cannot discharge, and can destroy the intensity of frozen soil, even can allow frozen soil melt.Therefore, the heat in frozen soil below ground need to be discharged, guarantee the stable of ground and building.

No. CN102011393A disclosed " a kind of hot pin arrangement of house foundation " patent (application number: 201010549056.4) of Chinese patent, by condensation segment and evaporator section, formed, wherein, evaporator section becomes W shape by many pipe weldings, and many bodys are interconnected at upper node and lower node place; Evaporator section is placed in house earth surface below, and a part is through ground body of wall, and a part is placed in the frozen soil of ground; Condensation segment is placed in the side of house sidings, and the lower end of condensation segment is connected with upper node.No. CN102401191A disclosed " hot pin of a kind of support on the ground and fixed pipelines " patent (application number: 200720104781.4), the endotherm section below it inserts in frozen soil layer, and above hot pin, heat release section is exposed in atmosphere of Chinese patent; Be located at two relative hot pins of pipeline both sides, its same position resting on the ground is provided with and the vertical support plate being connected of hot pin, and the support plate on two hot pins is relative, on two support plates of above-mentioned two hot pins, be provided with a crossbeam, this crossbeam is with pipeline suspension bracket is corresponding below, the bolt being meshed with pipeline suspension bracket upper end inner bolt hole is through the through hole on crossbeam, and by fastening nuts, the linkage unit of said structure is distributed on whole pipeline.The weak point of these two patents is: evaporator section becomes W shape to be placed in house earth surface below by many pipe weldings or inserts in frozen soil layer, and its heat absorption capacity is limited, and heat absorption efficiency is not high.

In addition, hot pin is again centreless gravity type heat pipe or thermal siphon, the steel pipe of a sealing, consists of, and the inside is filled with liquid nitrogen or other working medium, and radiator shutter is equipped with on the top of steel pipe, is referred to as condensation segment, is placed in atmosphere; The bottom of steel pipe is imbedded in ground ever-frozen ground, is called evaporator section.While there is the temperature difference, the heat absorption of the liquid nitrogen of evaporator section flashes to gas, under draught head effect, along pipe internal pore, rises to condensation segment, is condensed into liquid, and under Action of Gravity Field, along tube wall, flows down.Circulation, is transferred to the heat in frozen soil in atmosphere and so forth, thereby reduces the ground temperature of ever-frozen ground, to prevent that frozen soil from melting.

Summary of the invention the purpose of this utility model is exactly the rock-steady structure that a kind of plateau structure foundation simple in structure will be provided, and improves heat absorption efficiency.

In order to achieve the above object, the rock-steady structure of the plateau structure foundation that the utility model provides has many group hot pins, hot pin has condensation segment and evaporator section, wherein, every group of hot pin is comprised of 2 condensation segments and 9 evaporator sections, 2 condensation segments are positioned at building both sides, and 9 evaporator sections are arranged in ground below frozen soil; 9 evaporator sections are comprised of 4 inclined tubes and 5 vertical tubes; 4 inclined tubes are welded into two V-arrangement pipes, and two V-arrangement pipes are arranged in parallel up and down, two V-arrangement pipes between the upper and lower every distance be 30 to 50 centimetres, the too little heat absorption efficiency that affects in interval, interval is too greatly unfavorable for that construction settles; 5 upper and lower two ends of vertical tube are communicated with two V-arrangement pipes by welding, and 5 vertical tubes are uniformly distributed between two V-arrangement pipes, and the upper end of both sides vertical tube is connected with the lower end of 2 condensation segments respectively.In addition, the connected mode of the concrete structure of hot pin and condensation segment and evaporator section is prior art, repeats no more here.When the utility model is used, organize hot pin more and below structure foundation, form three-dimensional heat absorption net, can be timely and effectively by geothermal transfer in air.

The rock-steady structure of the plateau structure foundation that the utility model provides has positive effect: have many group hot pins, hot pin has condensation segment and evaporator section, wherein, every group of hot pin is comprised of 2 condensation segments and 9 evaporator sections, 2 condensation segments are positioned at building both sides, 9 evaporator sections are arranged in ground below frozen soil, 9 evaporator sections are comprised of 4 inclined tubes and 5 vertical tubes, 4 inclined tubes are welded into two V-arrangement pipes, two V-arrangement pipes are arranged in parallel up and down, 5 upper and lower two ends of vertical tube are communicated with two V-arrangement pipes by welding, 5 vertical tubes are uniformly distributed between two V-arrangement pipes, the upper end of both sides vertical tube is connected with the lower end of 2 condensation segments respectively, simple in structure, during use, many group hot pins form three-dimensional heat absorption net below structure foundation, can be timely and effectively by geothermal transfer in air, greatly improve heat absorption efficiency, be specially adapted to the heat radiation of structure foundation of heat affecting.
