The invention discloses a fiber foamed concrete and a preparation method thereof. The fiber foamed concrete comprises the following raw materials in parts by weight: 5290 parts of cement, 4965 parts of water, 1.361 part of foaming solution, 1.2964 part of fly ash and 10 parts of fiber. The preparation method comprises the following steps: proportionally weighing the components; sequentially adding the cement and fly ash into a stirrer, proportionally weighing the water, uniformly stirring the mixture by the stirrer, and adding the fiber; preparing and adding the foaming solution; gradually adding the foam into the mixture, and continuously stirring until all the components are uniformly mixed; pouring the mixture into a mold on which lubricating oil is brushed, and curing in a curing chamber; after 24 hours, removing the mold; and respectively curing for 3 days, 7 days and 28 days for experimental detection. The fiber foamed concrete has the advantages of favorable thermal insulation property, favorable compression resistance and favorable bending resistance, and is applicable to a railway bed strengthening layer.

The invention belongs to the technical field of multifunctional super-smooth surfaces, and discloses a super-smooth coating capable of continuously and automatically releasing lubricating liquid based on organic silicon resin. The super-smooth coating is obtained by mixing, stirring and carrying out cross-linking reaction on organic silicon resin, a cross-linking agent, a catalyst, an auxiliary agent, a filler and a lubricating liquid, coating the surface of the matrix, and curing. A substrate is coated with the super-smooth coating paint through simple construction, a super-smooth coating capable of continuously and automatically releasing lubricating liquid is obtained after cross-linking curing, the problem that storage of the lubricating liquid depends on a micro-nano structure can be effectively solved, and the super-smooth coating paint has stable and durable service performance.

The utility model relates to the technical field, in particular to a high-temperature-resistant cable protection tube. According to the technical scheme, the anti-splashing steel pipe comprises a pipe body, a heat-invaded plastic layer, a wear-resisting layer, an anti-splashing coating, a rope sleeve and binding rope bodies, the heat-invaded plastic layer is arranged outside the pipe body, the wear-resisting layer is arranged outside the heat-invaded plastic layer, the anti-splashing coating is arranged outside the wear-resisting layer, and the binding rope bodies are arranged on the anti-splashing coating at equal intervals. According to the utility model, the position of the cable protection pipe can be effectively positioned through the cooperation of the structures, and the anti-oxidation and high-temperature-resistant capabilities of the cable protection pipe are improved, so that the use effect of the protection pipe is improved.
