“…As shown in Figure 1b, in the case of grouting, some predictive friction resistance models are proposed. The Persson model, established by Ciavarella and Decuzzi, is suitable [18,31,33], as illustrated in Figure 2. The central force, denoted as P, is primarily focused at the arc of contact between the pipe and the adjacent soil [18,30].…”

“…An experiment on how the slurry concentration and standing time influence the friction characteristics was conducted [6], and it was found that both the contact pressure and pipe stress exhibit significant asymmetry during the jacking process; the magnitudes of contact pressure at the crown and the bottom exhibit relative proximity [17]. Comparisons of the calculation models have been made in terms of the pipe friction resistance and application conditions, resulting in a simplified calculation model to estimate the pipe friction resistance in the rock stratum [18]. In Ref.…”

Minimizing frictional resistance is crucial for ensuring the safety and smooth progress of pipe jacking construction. However, due to the unpredictability of geological conditions, it is difficult to grasp the frictional resistance during construction, which poses challenges to safe and smooth construction. In order to reduce the frictional resistance during the process of pipe jacking, an automated pipe jacking friction resistance identification and warning system is thus innovatively proposed. This system uses jacking resistance sensors to identify resistance during the jacking process. When the jacking resistance exceeds a certain threshold, the system will send alerts, which could prompt construction workers to adjust the rheological slurry ratio according to the on-site soil conditions. This system includes the following major components: (1) an analysis of primary factors influencing pipe frictional resistance and a model for resistance calculation, (2) the examination of forces exerted on disturbed soil during pipe jacking construction to determine the optimal placement of resistance sensors, (3) the design and operational principles for an automated resistance identification and warning system, and (4) the application of a slurry shield construction method for resistance reduction. The research has practical significance in providing a reference for developing intelligent pipe jacking and contributing to the improvement in construction safety levels.

“…Due to its environment-friendly nature, high construction efficiency, and low comprehensive cost [1], pipe jacking technology has been widely used in urban water supply and drainage, power tunnels, vehicle-mounted tunnels and other fields [2,3], accelerating the construction of urban infrastructure. However, the large diameter pipe jacking faces many problems in underwater curve jacking [4][5][6]. The formation properties directly affect the underwater pipe jacking construction, including the good permeability of sandy soil, which has a significant impact on the grouting effect of pipe jacking and the sealing between pipe joints [7].…”

The pipe jacking method is widely used in water supply and drainage, power tunnels, vehicle tunnel construction, and other fields. The main challenges include friction resistance, axis deviation, and environmental disturbance, especially when large-diameter pipes are jacked along the curve underwater. Based on a large-diameter pipe jacking project under Jinshan Lake, this paper records the settlement of surrounding structures, the jacking force, and the deviation in the axis and elevation during the jacking process. Furthermore, the factors affecting the monitoring data under different working conditions are studied, and the key points are concluded. The outcomes of the study will provide a reference and serve as a guidance for future related projects.
