After 6 consecutive days of intense construction by the engineering and technical personnel of the 7th Bureau of China Railway 16 Bureau Group with the Yellow River Project II-B, the tunneling P2.3 pump (mud pump) was completed on June 13 one day earlier than originally planned Pump body, ancillary facilities and circuit installation and connection, starting on the 14th debugging the machine, the shield can be restored within the recent excavation. The equipment installation and commissioning is a Chinese technician to independently complete. The shield machine used for tunneling of the Yellow tunnel is a mud-water balance shield machine. Ordinarily, the well-mixed composite slurry is transported to the excavator of the shield machine and mixed with the cut soil Together, and then through the pipeline using a mud pump pumped to the ground. Previously, a P2.1 pump was installed on the supporting trolley behind the shield machine to design a standard sludge discharge rate of 1,200 m3 / h. With the continuous tunneling, the current tunneling length has reached 660 meters, due to the pipeline continues to grow, the original P2.1 pump in the process of mud constantly declining strength, can not reach the standard discharge flow, it is Easy to cause blockage stoppipe phenomenon, so the actual installation of P2.3 pump P2.1 pump relay pump. When tunneling to 1500 meters to 2000 meters, but also additional installation P2.2 pump. P2.3 pump installed at the outlet of the tunnel at 550 meters, the entire set of equipment from the pump, 500KV motor, control cabinet, 10KV variable 400V transformer and 10KV high voltage switchgear and other components, belonging to a larger installation and commissioning of the construction process . Before the equipment is installed, the technicians of the construction unit conscientiously study the installation drawings and optimize and compare the plans. In the installation process, it overcomes the difficulty of hoisting the heavy and large equipment in the limited space of the tunnel. At the same time, The formed segment does not affect the segment, and makes reasonable use of the tunnel space without affecting the transportation and traffic capacity of the tunnel, thus achieving the requirements of reasonable layout, correct procedures, parameters and structural safety.
