Shenglong Injection packer for high pressure grout
Features
High pressure injection packers for concrete crack repairs , waterproofing ,rehabilitation of concrete structures , basement leak sealing cracksealing etc.
Shenglong injection packer for injection machine spare parts is uesd with the Shenglong injection machine in concrete crack repair and water leaking stop. It suits for both polyurethane and epoxy injection.
Method of Construction for Injection
1.Crack and leakage condition inspection
Check the process procedure after finding the thickness, width and depth of crack and leakage condition of the structure
2.Drilling Operation
Drill directly into crack section if the thickness of concrete is thinner than 10cm. For the thickness of 10~50cm, drill it with 45 degree angle by keeping a distance of 1/5 of concrete thickness. Make sure it penetrates the crack section. If the thickness is over than 50cm, keep the distance of 20~30cm and drill it with 45 degree angle until it penetrates crack section. And keep drilling by maintaining the fixed interval. (5 holes per 1 meter. Drill it in zigzags)
3.Packer Installation
Clean the inside of drilled holes with compressor. Make sure that rubber sleeve of packer and cutting line of tightening nut should be put into the inside of concrete surface when installing. Tighten the packer completely by using the T-box. (Packer might be damaged if you tighten it too strongly)
4.Injection Operation
Inject the waterstopping material by using the high pressure device or grease gun. Maintain the initial injection pressure as around 40kg/cm and increase the pressure by each 10kg/cm gradually until the waterstopping material flows out from crack section. Water will come out from the crack section first and then waterstopping foaming agent and then water stopping liquid at last. If the waterstopping material that is not foamed comes from the crack section, then move to next packer for injection.
5.Packer Removing Operation
Remove and break the packer by using vise pliers or hammer as a tool. If there is still a wet section, then inject the water stopping material again.
6.Finishing Operation
Remove the water stopping material that is remained on the crack section. Spreading with the elastic sealing material.
Failure phenomenon: batching station concrete trailer pump stone feed pneumatic door stones stuck not open. Analysis: batching station pneumatic door there is a big gap doors and small gap doors, big gap door its clearance greater than normal gravel particle size, so as to avoid the card material. Its small gap door gap is generally in the 5 ~ 10mm, 10mm below the stones card into the gap, it is difficult to pneumatic door jammed. Batching station after a period of use, the aggregate diesel engine concrete mixer spout wear, when the the gap wear to diesel concrete pump supplier 20 ~ 30mm, the card into the larger stones entering the gap in the process of the door, the gravel can easily stuck (wedge force) , pneumatic door can not be opened. Concrete mixing station troubleshooting method. twin shaft concrete mixer process: Check the pneumatic valve clearance and adjust to the appropriate value, can not be adjusted to the appropriate value as a result of excessive wear, you need to add welding steel plate or round bar in the feed opening, the gap reached a reasonable value. Take gray tank top, conveying powder to jar. Failure phenomenon: the bulk cement truck screw conveyer for sale the powder tank pump ashes, cement tank top with powder smoke. Analysis: conveying powder to powder cans transported by compressed air, compressed air, the powder to the powder cans into the air, such as dust removal machine cement mixing machine supplier filter clogging dust mobile concrete batching plant collector filter tank top, compressed air can not discharged generated "pressureout, and when the pressure reaches the safety valve opening pressure of the tank top, the safety valve opens, the diesel concrete pump for sale compressed air and powder through the safety valve is vented to the atmosphere, resulting in the risk ash phenomenon. Another level gauge failure, powder filled continue feeding also appears to take the gray tank top phenomenon. Process: 1, check movable concrete batching plants tank top dust filter and clean-up. 2, Once the take Ash phenomenon appears, you must clean up the safety valve around the powder, avoid powder caking the rain plug the safety valve. 3, as a result of the powder overfilled and take the gray, you must check on the level meter and a the material full alarm device reliability. Belt rainy slip. Fault slip phenomenon: a rainy day, inclined belt with load operation. Analysis: rainy, a moisture in the aggregate, and belt exposed parts easy to wet, damp, especially the inner ring and wet belt to screw conveyor reduce the coefficient of friction between the belt and the drive rollers, so that the drum is passed to the reduction in the belt torsional torch, the torque less than the belt material handling required torque, belt slipping.
