Grout plant for grouting in dam is a complete set of equipment which combines mixing machine and grouting pump together to carry out efficient and low-consumption work and effectively reduce complex procedures and remote operation. The grout mixer machine performs high speed mixing production and storage of cement slurry and similar materials, and then pumps the slurry directly to the construction junction to complete continuous mixing grouting.
Grout plant for consolidation grouting in dams lean concrete is mainly used in underground engineering construction. It can quickly mix water, cement, sand, bentonite, filler, clay, silicate and other media. Then by the plunger grouting pump grouting/grouting, to achieve waterproof plugging, tunnel lining, reinforcement of the foundation, rock, fill the void and so on. This series grouting pump has the advantages of compact structure, high grouting pressure and wide application range.
Features of grout plant for grouting in dams:
Compact structure, set up a pulping machine, mixer and grouting pump in a machine base.
With low - voltage, high - voltage and stepless speed control system.
The hydraulic system of grouting pump is composed of hydraulic components.
The function switch between mixer and pulping machine is realized by extruding valve.
The oil thermometer can automatically control the cooling fan to work within the normal temperature range, if the temperature is too high, the machine will automatically stop working.
Full hydraulic drive, motor or diesel engine as power source can be supplied. Easy to operate and maintain.
Grout plant for dams shall be capable of supplying, mixing, stirring and pumping the grout and additives, to the satisfaction of the Engineer. It shall be maintained at all times and any grout hole that lost or damaged due to mechanical failure of equipment or inadequacy of grout supply shall be replaced by another hole, drilled by the contractor at his expense. The amount of grouting equipment shall be as necessary to perform the work specified herein. The type to be furnished shall include the following.
A circulating grout header with control valves and a pressure gage with protector as shown on the plans. Control valves shall be connected to the return line and header. The header shall be joined directly to the riser pipe at the hole by means of a quick connector union.
Such valves, packers, pressure gages, pressure hose, supply lines, and small tools as may be necessary to provide a continuous supply of grout at accurately controlled pressures as specified. The inside diameter of the pressure hose and grout supply line shall be not less than 1 inches. An accurately calibrated, high precision pressure gage shall be used to check the accuracy of all gages used in the grouting. Gages shall be checked at least every 24 hours, or more frequently if the Engineer so determines. When defects are found, grouting operations will be stopped until calibration of gages has been obtained.
