During the construction of Wanxin Cement Pipe, jacking is a necessary work process. During the jacking process of Stone Cement Pipe, attention should be paid to the centerline and elevation control at all times. If errors are found, measures should be taken to correct them in time to prevent project errors. The use of the cement pipe will also get its function effectively used, so its use needs to be perfected first to improve the work process, so that the work of Wanxin cement pipe is effectively guaranteed. The editor of Guangzhou Wanxin Cement Pipe Manufacturer will tell you about the jacking method of four-way cement pipe construction.
1. When the first section of pipe is jacked, first pull out the steel gate of the gantry gate to strengthen the gantry gate. It is necessary to ensure that the front cutter head eats the soil uniformly and ensure that the cutter head gradually cuts the soil to avoid the pipe section from drifting before entering the soil and making the entire pipe section Jacking has a good start.
2. After the first section of pipe is inserted into the soil, in addition to controlling the center line, the pipe head should be slightly higher than the end of the pipe by about 10mm to avoid pushing into the middle.
3. During the jacking, follow the guidelines of rectification, slow correction, and avoid excessive increase of the error in the opposite direction caused by one correction.
4. During normal jacking, measure one meter per jacking, and measure it close to the exit. Always record the jacking length, elevation and centerline displacement, time, and jacking force during jacking. Take appropriate measures in time to ensure uninterrupted normal jacking and error control within 100 mm.
