The invention relates to the technical field of pipeline construction, and provides a quicksand stratum pipe jacking and pulling construction method which comprises the following steps that a receiving well and a pipe jacking well are manufactured at the front end and the rear end of a construction section respectively, water stop piles are manufactured along the outer side between the receiving well and the pipe jacking well respectively, and a gantry hole for a guide pipe to pass through is formed in the outer wall between the receiving well and the pipe jacking well; the guide pipe is guided into a pipe jacking well from a receiving well, a heading machine is connected with the guide pipe, a first pipe section is installed on the heading machine, the outer side of the first pipe section is wrapped with a flexible wrapping layer, the heading machine works, and after the part, except for a connector, of the first pipe section completely enters a gantry hole, the flexible wrapping layer is wrapped with the flexible wrapping layer; the gap between the flexible wrapping layer and the well wall is blocked through quick-setting cement, a new pipe joint is connected, the heading machine drives the pipe joint to move forwards till the first section of the pipe reaches the receiving well, and the heading machine is taken down through manual diving, the work of diving installation of the heading machine can be reduced, the safety of constructors is improved through the technology, and the working efficiency is high.
本发明涉及管道施工技术领域，提供一种流沙地层顶拉管施工方法，包括有以下步骤：在施工段的前后端分别制作接收井和顶管井，沿接收井和顶管井之间的外侧分别制作止水桩，在接收井和顶管井之间的外壁开出供导向管通过的龙门洞，导向管从接收井导向至顶管井内，将掘进机与导向管连接，将管材第一节安装于掘进机，管材第一节外侧包裹柔性包裹层，掘进机工作，待所述管材第一节除接口以外的部分完全进入所述龙门洞后，用快干水泥封堵柔性包裹层与井壁间的间隙，接上新管节，掘进机将管节带动前行，直至管材第一节抵达接收井内，人工下潜取下掘进机，本发明可以减少潜水安装掘进机的工作，该工艺提升施工人员的安全性，且工作效率高。
