Large-diameter pipe jacking and entering method
The invention provides a large-diameter pipe jacking and entering method, and belongs to the technical field of municipal pipe network construction facilities. The large-diameter pipe jacking and entering method is characterized in that an entering gesture of a pipe jacking machine is hard to determine, so that a hole foundation of a receiving well is reinforced; a pipe jacking machine receiving base is arranged in the receiving well; according to accurate gesture data of the pipe jacking machine checked by measurement, the pipe jacking machine is accurately located on the pipe jacking pipe receiving base through a receiving frame, the gesture of the pipe jacking machine is timely adjusted according to the measured data, and the pipe jacking machine is pushed toward a center position of ahole door so as to be ensured to accurately enter a wall through hole; aiming at the problem that front three sections of pipe joints get loose due to the sudden drop of front pressure, the pipe jacking machine is firmly connected with adjacent connectors of the front three sections of pipe joints before entering; and after the pipe jacking machine enters the hole, the pipe jacking machine cuts into the hole at the fastest speed, and a clearance between the pipe jacking machine and the wall through hole is blocked. According to the large-diameter pipe jacking and entering method provided by the invention, the construction operation process, the construction period can be shortened, the construction difficulty is reduced, and meanwhile, the stability and the safety of a vault structure arewell ensured.
本发明提供了大直径顶管进洞方法，属于市政管网施工设施技术领域。该大直径顶管进洞方法，顶管机进洞姿态难以确定，对接收井洞口地基进行加固措施，接收井的内部安装有顶管机接收基座，根据测量复核的顶管机准确姿态数据，使顶管机通过接收架准确就位在顶管机接收基座上，按测量数据及时调整顶管机的姿态，向洞门中心位置推进，确保顶管机准确进入穿墙洞，正面压力突降而造成前三节管节间的松脱，进洞前将顶管机与前三节管节的相邻接口连接牢固，顶管机进洞后，以最快速度切入洞口，并对顶管机与穿墙洞的间隙进行封堵。本发明在施工操作过程中能够缩短施工周期，降低施工难度，同时很好的保证拱顶结构的稳定性和安全性。
