Pipe jacking construction method based on plugging optimization and side friction reduction material
The invention discloses a pipe jacking construction method based on a plugging optimization and side friction reduction material. The pipe jacking construction method comprises the following steps that S1, a pipe jacking working well is excavated; the working well is provided with a cylindrical steel casing, a starting hole is formed in the side wall, in the pipeline jacking direction, of the lower portion of the steel casing, and the jacking pipeline penetrates through the starting hole. S2, grouting pipe pre-burying construction is carried out; an annular concrete water-stop wall is constructed at the starting hole in the working well, and a plurality of sets of grouting pipes are evenly pre-buried in the inner circumference of the water-stop wall; s3, water stop device construction; s4, breaking the starting hole; and S5, in the jacking process, thixotropic slurry is injected into the surrounding soil body of the jacking pipeline through the grouting pipe, and according to the jacking working condition, a Gaussian process machine is continuously adopted to learn'dynamic 'fitting and predict and optimize the ratio of the thixotropic slurry. The problem of water leakage of the working well is solved, friction resistance borne by the outer wall of the jacked pipeline can be effectively reduced, and smooth pipeline jacking is guaranteed.
本发明公开了一种基于优化封堵及降侧摩阻材料的顶管施工方法，包括以下流程：S1，开挖顶管工作井；工作井设有圆筒形的钢护筒，钢护筒的下部在管道顶进方向的侧壁上开设一始发洞口，使顶进管道贯穿在始发洞口中；S2，注浆管预埋施工；在工作井内的始发洞口位置施工呈环形的混凝土止水墙，在止水墙内圆周均布地预埋若干组注浆管；S3，止水装置施工；S4，始发洞口破除；S5，在顶进过程中通过注浆管向顶进管道的周边土体注入触变泥浆，并根据顶进工况，不断采用高斯过程机器学习“动态”拟合并预测优化触变泥浆的配比。本发明不仅解决了工作井漏水的问题，还能有效降低顶进管道外壁受到的摩擦阻力，保障管道顶进的顺利进行。
