| 注浆中要时常观察出浆压力表、各浆液的混合比和活塞的运动速度：随时观察料桶，看吸浆比例是否正确(如比例不对，将速度快的注浆缸的进浆管处阀门关小些或把吸浆管折一下，增加吸浆阻力)，如果比例仍不对，可能有的注浆缸有内泄漏，观察各出浆压力表(压力表有波动，但不会有回零现象)，如果压力表有回零现象，则该注浆缸可能有内泄漏，更换注浆缸密封及进浆管路密封。 During grouting, always observe the slurry pressure gauge, the mixing ratio of each slurry and the movement speed of the piston: at any time, observe the barrel to see whether the suction proportion is correct (if the proportion is not correct, turn down the valve at the inlet pipe of the fast grouting cylinder or fold the suction pipe to increase the suction resistance). If the proportion is still not correct, there may be internal leakage in some grouting cylinders, and observe each discharge pressure gauge (pressure gauge The pressure gauge fluctuates, but it will not return to zero). If the pressure gauge returns to zero, the grouting cylinder may have internal leakage. Replace the sealing of the grouting cylinder and the sealing of the grouting pipeline. |
