Attention should be paid to 19 safety problems in concrete pump construction
In the use of concrete pump construction, special attention should be paid to the construction safety problems, so every year, injured or killed people are not a few, today under the guidance of Xiao Bian, I hope you can seriously read this article.
The pumping equipment should be kept at a certain distance from the edge of the foundation pit.
Two, when the wind is greater than six and above, the concrete pump truck shall not use the cloth pole. When the weather is hot application of wet sacks, straw cover pipe temperature.
Three, the horizontal pumping pipeline laying line reasonable, pipeline and pipe support must be fastened and reliable, the pipe joint should be sealed reliable.
Attention should be paid to 19 safety problems in concrete pump construction
Four, sand particle size, cement mark and mixture ratio should meet the pump requirements of concrete pump. When pumping, the material in the hopper should be higher than the height of the suction inlet, so as to prevent the air from wounding.
Five, the vertical pipe is not directly installed in the pump outlet, should be erected on the vertical pipe installed in front of the length of not less than 10m horizontal pipe, the horizontal pipe near the pump should be equipped with check valve. When laying down the inclined pipe, the lower end should be equipped with a horizontal pipe, whose length is at least five times higher than the inclined high generational difference, otherwise it will be bent by organic pipe. Increase Yin force. If the inclination is large, the exhaust valve should be installed at the upper end of the ramp so as to exhaust the air.
Six. The parking brake and lock brake should be used at the same time, and the tire should be tightened. The cooling water supply is normal, the water tank should be filled with clean water, the hopper should be free of debris, and the lubrication points should be lubricated normally.
Seven. Prepare cleaning pipes, cleaning supplies, catching devices and related devices. Before the operation of concrete pump, the cement mortar lubrication pipeline must be used first. The irrelevant personnel must leave the pipeline.
Eight, legs should be extended and solid, not to start the cloth rod before the solid. The boom is lifted away from the support and then turned. The cloth rod should be stretched out in sequence. It is prohibited to hoist or drag objects with a cloth pole.
Nine, when the cloth rod is fully extended and solid, it is strictly prohibited to move the body. When the operation needs to move, the upper cloth bar should be folded and fixed, and the moving speed should not exceed 10km/h. The boom may use more than the required diameter pipe, connected with hose should be anti drop safety belt.
Ten, should monitor all kinds of instrument and indicator lamp at any time, found abnormal, should be timely adjustment or processing. If the pipeline is blocked, should make the concrete pump pump or anti return hopper, should remove the pipe blockage removing when necessary.
Eleven, pumping work should be continuous operation, must be suspended when the guard 5~10 minutes (winter 3~5 points) pumping once. If the pump is stopped for a longer period of time, the pump should be pumped one or two times, and then the pump is pumped. When pumping, the hopper should maintain a certain amount of concrete, not suction. Eighteen. Run the piston on both sides into the cleaning room and apply lubricating oil.
Twelve, each part of the control switch, adjusting handle, handwheel, control rod, cock and so on should reset. Hydraulic system unloading.
Thirteen. Run the piston on both sides into the cleaning room and apply lubricating oil.
Fourteen, should keep the water tank full of water, found turbid water and there are more sand, should be timely inspection and treatment.
Fifteen, pumping equipment bolts should be fastened, the pipe joints should be tightened and sealed, protective devices should be complete and reliable.
Sixteen, various parts of the beginning of operation, high speed handle, handwheel, control rod, cock and so on should be in the right position. The hydraulic system should be normal without leakage.
Seventeen, pumping system under pressure, shall not open any conveying pipe and hydraulic pipeline. The safety valve of the hydraulic system shall not be adjusted arbitrarily, and the accumulator can only be charged with nitrogen.
Eighteen, after the concrete pump operation, must be inside the hopper and the concrete pipe all output, and then the concrete pump, hopper, pipeline cleaning. Compressed air flushing pipeline, pipeline outlet not stand in front 10M, foam rubber and sand particles and application of metal basket collection out of.
Nineteen. It is strictly prohibited to use compressed air to wash distributing rod piping. The folding and contraction of the distributing rod should be carried out in sequence.
Only when the performance and taboo of the equipment are thoroughly understood, can the work be carried out safely and effectively.
