Description
Technical Field
[0001] The utility model belongs to the technical field of outlet holes for hydropower and pumped storage projects, and in particular relates to a fireproof partition wall suitable for outlet holes that can be flexibly disassembled and assembled. Background Art
[0002] The underground powerhouse outlet hole is a passage built for laying the underground powerhouse lead-out wires. When the main transformer is arranged on the ground, it is used to lay the generator voltage lead-out wire; when the main transformer is installed underground, it is used to lay the high-voltage lead-out wire after the voltage is increased. The outlet hole also needs to lay a certain amount of control cables, leave space for transportation and maintenance, and pay attention to ventilation and moisture-proof.
[0003] In current engineering practice, the fireproof partition wall of the cable hole usually adopts 240mm thick autoclaved lime sand brick masonry wall or light steel frame gypsum board partition wall as the fireproof partition wall. The specific method of masonry wall is to use 240 autoclaved lime sand brick (strength ≥ MU10) for masonry, φ6@200 (bidirectional) steel bars on both sides of the wall, and φ6 tie bars @600 arranged in plum blossom shape to fix the wall, and apply 20 thick 1:2.5 cement mortar. This technical solution of masonry wall has the following disadvantages:
[0004] (1) In order to ensure the time schedule of the reverse power transmission project, the cables are usually laid first and then the walls are built. Since the cables are energized after being laid, it is very difficult and dangerous to build the walls at this time, which is not conducive to safe and civilized construction.
[0005] (2) When cables need to be added, repaired or replaced, the 240 mm thick autoclaved fly ash brick masonry wall needs to be demolished, which pollutes the operating environment and has disadvantages such as difficulty in construction organization.
[0006] (3) This integrated fireproof partition wall is also inconvenient in actual use, especially when carrying out secondary cable laying construction. The disassembly of the overall structure of the fireproof partition wall is cumbersome, time-consuming and labor-intensive. Construction workers are prone to damage high-voltage cables when disassembling the fireproof partition wall, which increases the difficulty of construction and affects the construction progress.
[0007] This technical solution of light steel keel gypsum board partition has the following disadvantages:
[0008] (1) Since the outlet hole is located underground and the environment is always humid, the gypsum board will become moldy and rot after being exposed to moisture, which will affect the service life and reduce the fire resistance limit. It cannot prevent the spread of fire to a limited extent, which will bring fire hazards. (2) When welding and connecting light steel keels, sparks are easily generated, which brings fire risks. Once a fire occurs, the consequences are serious.
[0009] Therefore, it is a technical problem that technical personnel in this field urgently need to solve to provide a fireproof partition wall that can be quickly and normally disassembled and installed while maintaining the fire-resistant performance indicators of the fireproof partition wall, which is convenient for adding cables and laying them later, reduces the difficulty of construction, improves construction efficiency, has good durability and sound insulation, is easy to construct, can be reused, and is efficiently disassembled and assembled.
