Problems solved by technology

When the high and low voltage power distribution room is soaked in water, it is unavoidable to avoid short circuit due to water, causing accidents and even explosions
If only waterproof materials such as cement are used for sealing in the above construction, due to the poor fire resistance of cement and other waterproof materials, they are easy to burn and crack when a fire occurs, and cannot prevent the flame from spreading; in addition, cement and other waterproof materials have high strength after curing and are not easy to disassemble and Overhaul and replace cables

Embodiment Construction

[0006] The embodiments of the present invention are further described in detail below.

[0007] The invention provides a plugging material which is fireproof, waterproof, and convenient for cable replacement. The plugging material contains fly ash; fireproof material; cement, and the proportion in parts by weight is:

[0008] Fly ash: fireproof material: cement = 6.5-7: 2-2.5: 0.5-1.5.

[0009] The fireproof material is one selected from vermiculite, refractory clay and quartz powder.

[0010] The plugging material also contains a waterproofing agent, and the ratio of the waterproofing agent to the plugging material in parts by weight is: waterproofing agent: plugging material = 1:10.

[0011] The waterproofing agent is selected from high-efficiency water-tight and leak-stopping agents.

[0012] In the plugging material of the present invention, the larger proportion is fly ash, and the fly ash is a waste material from a power plant. 25.0; burning vector (%) ≤ 8.0; water de...

Abstract

The present invention discloses a plugging material which has fire-proofing and water-proofing functions and can be used for conveniently removing and replacing electric cable. Said plugging material is made up by using fly ash, fire-proofing material and cement according to the mixing ratio of 6.5-7:2-2.5:0.5-1.5 through a certain preparation process. It can be extensively used in plugging engineering of power plant, transformer station, switchboard room and high-voltage and low-voltage distribution boards, etc.

Description

technical field [0001] The present invention relates to a special plugging material for fireproof and waterproof plugging engineering of high and low voltage power systems, and particularly relates to a plugging material for plugging the electric channels of high and low voltage power distribution rooms, which is fireproof, waterproof and convenient for cable replacement. . Background technique [0002] At present, for high and low voltage power systems, fire prevention and waterproofing are the most important measures to ensure the safety of power equipment. With the rapid development of the national economy, the power industry and its power safety protection are also more important. Wires and cables in modern buildings are often laid in clusters in cable channels, and there are many penetrating openings, which inevitably poses a fire hazard. When a fire occurs and the cable burns, the flame will spread to adjacent houses through the cable channel through the wall, floor,...
