Top plate non-contact box culvert jacking construction method
The invention discloses a top plate non-contact type box culvert jacking construction method. The top plate non-contact type box culvert jacking construction method comprises the following steps that S1, a shield system is installed at the front end of a box culvert; s2, a top sealing component is arranged at the top end of the shield system, and the upper surface of the top sealing component is flush with the top end face of the box culvert; s3, a resistance reduction system is installed and comprises a winding drum arranged in the shield system, an isolation steel plate wound around the outer side of the winding drum, a tail fixing piece arranged at the tail end of the roadbed and a lubricating grease coater used for coating the two surfaces of the isolation steel plate with lubricating grease, the end, away from the winding drum, of the isolation steel plate is laid above the top sealing component and the box culvert and then connected with the tail fixing piece. S4, a jacking system is installed; and S5, the box culvert is jacked, in the box culvert jacking process, the winding drum continuously releases the isolation steel plate, and the box culvert and the roadbed tunneling face are isolated. The box culvert jacking construction method has the advantages that the situation that the soil body of the roadbed tunneling face moves along with the box culvert in the box culvert jacking construction process is reduced, and secondary disturbance to the soil body of the roadbed tunneling face is avoided.
本申请公开了一种顶板非接触式的箱涵顶进工法，其包括以下步骤：S1、将盾构系统安装于箱涵前端；S2、在盾构系统顶端设封顶构件，使封顶构件的上表面与箱涵的顶端端面平齐；S3、安装减阻系统，减阻系统包括设于盾构系统中的卷筒、绕设于卷筒外侧的隔离钢板、设于路基尾端的尾部固定件和用于对隔离钢板的两表面涂附润滑脂的润滑脂涂布器，隔离钢板背离卷筒的一端铺设于封顶构件及箱涵上方后与尾部固定件连接；S4、安装顶进系统；S5、箱涵顶进，箱涵顶进过程中，卷筒将隔离钢板不断放出，隔离了箱涵与路基掘进面。本申请具有减少了箱涵顶进施工过程中路基掘进面的土体随箱涵跟随移动的情况，避免对路基掘进面的土体二次扰动的效果。
