Clever thoughts to solve problems: fast converter help smooth construction
In the field of construction machinery, every project is unique, so the difficulties faced by the construction team are also different. But for human intelligence, these problems can be solved easily. In the five-star Ping tunnel construction process, the team 15 seconds to quickly adapted to digging through the converter captain Zhu Hao, successfully solved the problems of the special soil excavation engineering, make the whole construction progress is greatly accelerated.
The total length of the Five Star Ping tunnel in the Lanzhou hub of LAN (CHO) LAN (state) guest school is 6449 meters long. It belongs to the long loess tunnel, and the risk of construction safety is very large. The entrance section is 20 meters deep, and the deepest part is only 2 meters. The geological condition is poor, the bias pressure is serious, the rock mass structure is loose, and the stability is poor. There are many pitfalls, and there may be large collapse or slip at any time. The safety risk is huge.
Zhu Hao participated in the Dingyuan test field, Funing expressway, BOLN passenger dedicated 11 standard construction of the project, the four Bureau of China railway passenger hub of Lanzhou BOLN 3, responsible for the five-star Ping tunnel entrance construction task of 1268 meters. Zhu Hao, five-star Ping tunnel entrance to IV level rock, local rock hard, simply dig working face surrounding rock excavator bucket teeth, the other tunnel is a digging machine with breaker with the other excavators but the loess tunnel excavating face, vertical joints, hammer on the disturbance of surrounding rock, easy to off the block. Mechanical knowledge accumulated useful, Zhu Hao take the initiative to contact the rapid conversion to machinery factory converter excavator, excavator bucket and only the conversion between the Ripper in 15 seconds. This improvement not only greatly reduces the disturbance to the surrounding rock during the excavation, but also avoids the construction interference between the two excavators. In this way, can save an excavator working face excavation, can at least cost savings of 500 thousand yuan per year.

As the management in place, standardized management and the construction progress of the five-star Ping tunnel entrance has been leading across the board, and has set a single face hole into a 110 metre record in the line. These two days, the five-star Ping tunnel entrance portal is successfully completed to team captain Zhu Haosong said, in 2016 May through the tunnel to ensure they have laid a good foundation.
