The use of concrete pump safety requirements: (1) gravel diameter, cement label and mix according to the requirements of the factory manual to meet the mechanical requirements of the pump. (2) The parking brake and locking brake of pumping equipment should be used at the same time. The tire should be wedged tightly. The water supply should be normal and the water tank should be filled with clean water. There should be no debris in the hopper. The lubrication points should be lubricated normally. (3) The bolts of each part of the pumping equipment should be fastened, the pipe joint should be tightly sealed, and the protective device should be complete and reliable. (4) the beginning of the various parts of the operation, adjust the handle, hand wheel, lever, cock, etc. should be in the correct position. Hydraulic system should be normal without leakage. (5) ready to clean the pipe, cleaning supplies and other related devices. Before work, you must first use the cement mortar formulated in accordance with the provisions of the lubrication pipe. Irrelevant people must leave the pipeline. (6) The outriggers shall be fully extended and securely fastened, and the fabric rod shall not be actuated without being fixed. After the fabric rod is raised, it can rotate. Fabric rod should be out in order when proceeding. Do not use the cloth rod lifting or hauling objects. (7) When the cloth rod is fully extended state, the body is strictly prohibited to move. 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, pipe should be attached to the anti-off safety rope. (8) Various kinds of meters and indicator lights should be monitored at any time, and if not found, adjust or handle it promptly. In case of blockage of the delivery pipe, reverse operation should be carried out to return the concrete to the hopper, and the pipe should be disassembled if necessary. (9) When the pumping system is pressurized, do not open any delivery pipe and hydraulic pipe. Hydraulic system safety valve shall not be arbitrarily adjusted. Accumulator can only be filled with ammonia. (10) After operation, all the concrete in the hopper and the pipe must be output, then the pump, hopper and pipe should be cleaned. When flushing the pipeline with compressed air, no person shall stand on the front side 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. (11) It is forbidden to flush the fabric rod piping with compressed air. Cloth folding contraction of the order to be carried out. (12) various parts of the control switch, adjust the handle, hand wheel, control sweat, cock, etc. should be reset. Hydraulic system unloading. Pumping concrete construction is a complicated task, which requires continuous summarization of experience in construction practice, improvement of technology and improvement of construction level so as to reduce construction cost.
