The figure of eight between the wall and the plate of the building fire pool is usually called the "figure of eight slot". The main purpose of this structural design is to increase the capacity of the fire pool, so as to provide enough water for firefighters in case of fire.
The design principle of the splayed tank is to increase the capacity of the tank by using the space between the tank wall and the board surface. The depth, width and length of the splayed tank should be considered in the design to ensure that it meets the requirements of fire water source.
The material of splayed groove is usually concrete or reinforced concrete, which has high strength and durability and can withstand water pressure and external pressure. In the manufacturing process, it is necessary to pay attention to the sealing and waterproofing of the splayed groove to ensure that it can effectively store fire water sources.
