The invention relates to a composite heat insulation wallboard and a manufacturing method thereof. The composite heat insulation wallboard is characterized by comprising a bottom surface layer; the top of the bottom surface layer is connected with a heat insulation layer made of a cement foaming material, a layer of grid-shaped metal framework is embedded in the heat insulation layer close to the top, and the top of the heat insulation layer is connected with a decorative layer; and the left and right sides or left, right, upper and lower sides of the metal framework are provided with circular tubes or square tubes exposed out of the heat insulation layer and used for mounting dry-hang clips. The composite heat insulation wallboard has the characteristics of light weight, high integral strength, good decoration performance and the like at the same time of ensuring the effects of heat insulation and heat isolation; and the manufacturing method is convenient to mount and operate on site, can finish a plurality of working procedures of heat insulation, decoration, reinforcement and the like at the same time during once mounting, and has strong practicability. The composite heat insulation wallboard and the manufacturing method thereof can be widely applied to the occasions of outer heat insulation of outer walls of various buildings or building roofs, and the like.

The invention discloses a high-thermal-conductivity organosilicone mud. The high-thermal-conductivity organosilicone mud is prepared from the following raw materials: 100 parts of silicone oil and 1000-1200 parts of heat-conducting powder filler in parts by weight, 0.5-1wt% of plasticizer and 1-3wt% of powder surface treating agent in terms of the heat-conducting powder filler, and 1-3wt% of cross-linking agent, 5-10wt% of high temperature resistant pigment and 0.01-0.015wt% of platinum catalyst in terms of the silicone oil. Besides, the invention also discloses a preparation method of the high-thermal-conductivity organosilicone mud. The high-thermal-conductivity organosilicone mud product has the advantages of high thermal conductivity, stable heat transfer property, excellent high temperature resistance, plasticity just as plasticine and the like; the preparation method of the high-thermal-conductivity organosilicone mud is simple; a better thermal-conductivity solution way can be provided for electronic heating components and radiating or other cooling devices.

The invention relates to the technical field of railway ballastless track disease eliminating, in particular to a temporary steel rail supporting device for disassembling and replacing railway ballastless track supporting layers. The temporary steel rail supporting device comprises steel sleeper beams for supporting temporary passing steel rails and supports fixed on supporting layers below existing rails at the two longitudinal ends of a to-be-constructed area. The steel sleeper beams include two longitudinal beams arranged in the longitudinal direction of the rails and the transverse beams located between the two longitudinal beams, the two ends of the longitudinal beams are laid on the upper end faces of the supports and anchored on the supporting layers below the existing rails at the two longitudinal ends of the to-be-constructed area, the transverse beams are arranged in the transverse direction of the rails, and the two ends of the transverse beams are fixed to the lateral portions of the two longitudinal beams respectively. According to the temporary steel rail supporting device, the steel sleeper beams are used for erecting the construction area overhead and supporting the passing steel rails, a railway line can normally run without stopping, and normal running of the rails is guaranteed; in addition, the disease problem in the supporting layers below the rails and lower structures of the rails can be thoroughly solved, hidden dangers of the rails can be thoroughly eliminated, and high popularization value is achieved.
