[Asia Pump Network News] construction site construction operations, we must pay attention to safety, site environment is dangerous everywhere. Now to talk about concrete pump construction should pay attention to safety issues. Concrete pump construction 19 points should pay attention to the construction of concrete pump safety issues First, the pumping equipment should be placed at the edge of the excavation to maintain a certain distance. Second, the wind is greater than six and above, the concrete pump truck shall not use the cloth rod. When the weather is hot wet sacks, warm straw bags cover the pipeline. Third, the level of pumping pipe laying line Qing Qing reasonable, pipe and pipe support must be tight and reliable, pipe joints should be sealed and reliable. Fourth, gravel diameter, cement label and mix should meet the concrete pump pumpability requirements. Pumping, hopper material should be higher than the height of the intake port, to prevent air intake wounding. Fifth, it is strictly forbidden to directly attach the vertical pipe to the outlet of the pump. The front pipe should be equipped with a horizontal pipe with a length of not less than 10m and the check valve should be installed near the horizontal pipe. Laying downward sloping pipe, the lower end should be connected to a horizontal pipe, the length of at least five times the height of the tilt difference, or on the other way with organic pipe. Increase the negative force. Such as the inclination of larger, if necessary, should be installed at the top of the ramp valve exhaust valve to facilitate the exhaust. Six, pumping equipment, parking brake and lock braking should be used at the same time, the tire should be wedge tight. Cooling water supply is normal, water tank should be filled with water, hopper should be no debris, the lubrication points should be normal lubrication. Seven, ready to clean the pipe, cleaning supplies, catcher and related devices. Before concrete pump operation, it must first be used in accordance with the provisions of the preparation of cement mortar lubrication pipe. Irrelevant people must leave the pipeline. Eight, legs should all be extended and solidified, not support before the start of cloth rod. Cloth pole lift away from the back of the bracket. Fabric rod should be out of order when. It is strictly forbidden to lift or pull objects by cloth rod. Nine, when the cloth rod in all the stick out and support, non-moving body. When the work needs to be moved, the cloth rod in the upper section should be folded and fixed, and the moving speed should not exceed 10km / h. Fabric rod shall not use more than the specified diameter of the pipe, the hose should be attached to prevent the safety rope. Ten, you should always monitor a variety of instruments and lights, abnormalities should be promptly adjusted or dealt with. Such as the emergence of pipeline congestion, the line should be anti-pump back to the concrete pump hopper, if necessary, remove the plug to remove the block. Eleven, pumping work should be continuous operation, must be suspended for 5 to 10 minutes (winter 3 to 5 points) to pump once. If you stop pumping for a longer time, you should pump one or two times, and then pumping material. Pumping hopper should maintain a certain amount of concrete, not suction. Eighteen, the pistons on both sides of the cleaning operation room, and coated with lubricating oil. Twelve, all parts of the control switch, adjust the handle, hand wheel, lever, cock, etc. should be reset. Hydraulic system unloading. Thirteen, both sides of the piston to the cleaning chamber, and coated with lubricating oil. Fourteen, should keep the water tank full of water, found that water quality and more sand should be promptly checked. Fifteen, the pumping equipment bolts should be fastened, pipe joints should be tight seal, protective devices should be complete and reliable. Sixteen, the beginning of the various parts of the operation, high-speed handle, hand wheel, lever, cock, etc. should be in the correct position. Hydraulic system should be normal without leakage. Seventeen, pumping system under pressure, shall not open any duct and hydraulic pipe. Hydraulic system safety valve shall not be arbitrarily adjusted, the accumulator can only be filled with nitrogen. Eighteenth, concrete pump operation, the hopper must be within the concrete and pipe all output, and then on the concrete pump, hopper, pipe cleaning. When flushing the pipeline with compressed air, no person shall stand in front of the outlet of the pipeline within 10M, and foam metal such as foam rubber and gravel should be collected by using a metal basket. Nineteen, strictly prohibited with compressed air flushing fabric rod piping. Collapsing of fabric rods should be done in order.
