Pipe jacking construction system
The invention relates to a pipe jacking construction system. The pipe jacking construction system comprises a pipe jacking machine installed in a working well, a jacking device installed at the front end of the pipe jacking machine and a tool pipe installed at the front end of the jacking device, and the tool pipe comprises a cylindrical pipe body and an arc-shaped plate coaxially fixed to the radial inner side of the pipe body. The arc-shaped plate is fixed to the top of the pipe body and forms a cavity with the inner side wall of the pipe body. A pushing mechanism, a connecting piece connected with the pushing mechanism and a top cover connected with the connecting piece are sequentially arranged in the cavity from back to front, the top cover is integrally in a circular arc shape, the top cover is coaxially arranged in the cavity, the top cover can stretch out of or retract into the cavity along with the pushing mechanism, and the outward side of the top cover is a cutting edge capable of cutting into a soil layer. A monitoring system used for monitoring construction is further included. The top cover can be cut into the soil layer before excavation to form a protective cover, so that the soil layer above the top cover is not prone to collapse after the soil layer below the top cover is excavated, the safety of constructors can be guaranteed, and settlement caused by collapse can be avoided.
本发明涉及一种顶管施工系统，包括用于安装在工作井中的顶管机，安装在顶管机的前端的顶进装置，安装在顶进装置的前端的工具管，工具管包括圆筒状的管体和同轴固定在管体径向内侧的弧形板，弧形板固定在管体的顶部且与管体内侧壁之间形成腔体；腔体内部从后向前依次设置有顶推机构、与顶推机构连接的连接件、与连接件连接的顶盖，顶盖整体呈圆弧形，顶盖同轴设置在腔体内，顶盖能够随顶推机构伸出或缩入腔体，顶盖的朝外的一侧为能够切入土层的刃口；还包括用以监测施工的监控系统；顶盖能够在开挖前切入土层，形成保护盖，使顶盖下方的土层挖凿后，顶盖上方的土层也不宜塌方，既可以保障施工人员的安全，又可以避免塌方引起的沉降。
