Underground fire pump station without bottom plate, integrated pump station with buried fire water tank

Description :

　　Underground fire pump stationSelection of integrated fire pump room: The model of the fire pump unit is determined based on the design flow rate and required fire water supply pressure of the fire water supply system in the engineering project. The water pump should be one in use and one as backup, and the pressure at zero flow should not exceed 140% of the system design pressure; When the system flow rate is 150% of the rated flow rate of the water pump, the pressure should not be lower than 65% of the rated pressure. The fire water tank calculates the required fire extinguishing water consumption for each individual fire water supply system based on the fire design flow rate and fire duration of each individual fire water supply system in the engineering project. When a construction project consists of multiple fire water supply systems, the total amount of water used for extinguishing a single fire is the sum of the water used for extinguishing each individual system. From this, the effective volume of the fire water tank is determined, and the size of the fire water tank can be determined based on the tank volume and the actual situation on site. The main channel width of the underground fire pump station without a bottom plate should not be less than 1.2m, and the width of the channel in front of the electrical control cabinet should not be less than 1.5m. A 2m × 2m maintenance port should be set at the top of the pump room, which should be at least 200mm above the ground. A sliding rail type top cover should be added to the top of the maintenance port for easy opening and closing; Install escalators in the pump room for easy access; Ventilation pipes should be installed at the top of the pump room, with a height of at least 1.5m above the ground. The composite BDF module uses hot-dip galvanized steel plates of 3mm and 0.4mm 304/2B food grade stainless steel plates, which are pressed and compounded by equipment to achieve a tight fit, thus meeting the requirements of steel plate material strength and stainless steel corrosion resistance. The underfloor buried fire pump station is pressed and formed, and then punched by equipment to meet the assembly requirements of standard modules. On site assembly and selection of 10 # national standard hot-dip treatment for foundation channel steel, combined with a spacing of 1 meter between each beam, and so on. Assemble according to the atlas and technical requirements, and assemble with Φ 10 * 30 hot-dip galvanized screws and environmental protection, water resistance and anti-aging adhesive strips. After the water tank is assembled and formed, install the tie bars and top columns. The reinforcement is made of hot-dip galvanized steel with a diameter of 48, and is installed horizontally and vertically at a distance of 1 meter. The top pillar is sealed with 4 hot-dip galvanized pipes of diameter 48 evenly distributed per square meter.
