During the construction of Wanxin Cement Pipe, jacking is an indispensable operation step. During the jacking process of Stone Stone Cement Pipe, it is necessary to pay attention to the centerline and elevation control at all times. When errors are found, corrective measures shall be adopted in time to prevent errors in the project. The use of through-cement pipes will also be effectively used. Therefore, the use of the through-cement pipes needs to be perfected first to ensure the effective operation of the four-way cement pipes. The editor of Guangzhou Wanxin Cement Pipe Manufacturer will tell you about the jacking method of Wanxin Cement Pipe during 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 cutter head at the front end 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 an outstanding 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. In the jacking, we must abide by the rules of on-the-spot correction, slow correction, and avoid the excessive increase of correction in the opposite direction.
4. During normal jacking, measure one meter per jacking. Encrypt the measurement when approaching the exit, and keep a record of jacking length, elevation and centerline displacement, time and jacking force during jacking. Adopt corresponding measures in time to ensure uninterrupted normal jacking and error control within 100 mm.
