Precautions for the construction and operation of mixing integrated grouting: When grouting, you should always pay attention to the instructions of the pressure gauge. If the instructions of the pressure gauge or the pressure is exceeded, when the safety device does not work, the cause should be identified, and the fault should be cleared before starting.
Precautions for the construction and operation of mixing integrated grouting: When grouting, you should always pay attention to the instructions of the pressure gauge. If the instructions of the pressure gauge or the pressure is exceeded, when the safety device does not work, the cause should be identified, and the fault should be cleared before starting.Pay attention to whether the structure of the grouting pump and motor is normal. When any faults are found, stop immediately, open the grouting valve to reduce the pressure and resolve the faults.Care should be taken often to make the Gran compress the packing so that it does not leak.If there is still leakage in the compression, the packing or piston should be replaced according to the specific circumstances.The stirred mortar should be measured for consistency before entering the pump. During the test, the consistency meter should be perpendicular to the slurry surface, and it can be easily lowered to sink by its own weight.After the shutdown at the end of each shift, water must be pumped immediately to clean the pipeline and the inside of the pump until it is cleaned to ensure that the ball valve, slurry discharge port, slurry suction port, and slurry discharge valve are clean and smooth.The oiling chamber should be filled with oil.
Core technology: (1) Core one: Through the embedded radial RPC pipe, the thickness of the lining of the vault is predicted, and the overflow of the RPC nozzle is observed when the concrete is poured, so as to solve the problem of insufficient lining thickness.(2) Core two: Mold grouting is carried out in time after the concrete filling is over, and the nozzle of the grouting pipe is overflowing, indicating that the grouting is full and the problem of vault emptying is solved. (3) Due to timely grouting, the slurry is completely combined with the concrete, and the integrity of the lining structure is good.(4) By counting the amount of grouting per ring, the concrete filling construction of the vault can be inverted. At the same time, infrared rays can be installed on the roof of the lining platform for monitoring and filling.2. Fully functional, it can be injected with either a single-component slurry or a two-component slurry; it can be injected with chemical slurry or water slurry; each cylinder works synchronously, the mixing ratio is ok, the mixing is uniform, and it can also be used as an emulsion pump or a high-pressure water pump, hydraulic pump, etc., for other purposes.After the operation of the mortar putty machine: 1. Cleaning and inspection of grouting hoses, air ducts, and sprinklers 2. Cleaning and inspection of equipment 3. Air compressor.Cut off the power supply, air source, close the valves, and inspect all parts.4. The electrical part is cut off from the power supply and all parts are inspected.5. Remove the booster nails and rotors, and reassemble after cleaning.6. Other handling of problems found in operation, cleaning, etc.
The cement grouting machine needs to clean the equipment, and then use clean water for cleaning, and it also needs to be on site at any time.Organize personnel to inspect the construction area, operations, facilities and equipment used, and workers to confirm that they meet the requirements. Once the construction starts, it means that the construction site, operations, facilities and equipment, and workers have been confirmed to meet the requirements and are in good condition.Before cleaning up, all personnel must carefully study and understand this measure and clean up strictly in accordance with the requirements of the measure.The purpose of the utility model is to provide a mixing grouting machine. The mixing grouting machine is a new type of equipment integrating mixing, slurry storage and grouting. Its structure is reasonable, convenient, easy to use and high efficiency to solve the shortcomings of the prior art.The technical solution to the above problems is a mixing grouting machine, which includes a mixing part, a slurry storage part and a grouting part all installed on the same rack; the mixing part is a mixing barrel with a high-speed centrifugal pump installed at the bottom, on which there is a water injection port and a feeding port; the slurry storage part and the grouting part are installed together, and the slurry storage part located in the upper part includes a slurry storage barrel with a stirrer installed, and the grouting part installed in the lower part includes a grouting pump and a slurry delivery pipe to prevent the grouting pump from drying out. The intelligent control part of the electrical appliances is installed on the rack, through a cable and The grouting pump is electrically connected, and the pipes of the water tank are respectively connected to the mixing barrel of the mixing part and the slurry storage barrel of the slurry storage part, and the mixing part, the slurry storage part and the grouting part are connected through the internal slurry delivery pipe.
