The risk management in the pipe jacking machine is to analyze the risks in the pipe jacking machine through risk identification, risk estimation and risk evaluation. Based on this, a variety of methods and means are used to effectively implement the risks involved in the pipe jacking machine. It is a general term for the whole process of controlling the risk events, maximizing the beneficial results of the risk events, and properly handling the adverse consequences caused by the risk events. Including several stages such as risk identification, risk evaluation and risk control.

1. Identification of risks

　　1) Factors in hydrogeology and engineering geology. The geological soil layer where the pipe jacking machine is located changes frequently. If the hydrogeological data is inaccurate before construction starts, construction accidents will be caused.

　　 2) Influencing factors in design. The reliability, scientificity, and pertinence of the design plan will also affect the construction process.

　　3) Construction factors. The selection of construction methods, the selection of construction equipment, the deployment of personnel and the quality of personnel will all affect the construction.

　　4) Economic factors. For example, the cost of the project and the availability of funds will affect the organization and management of the construction unit. If the bid price of the project is low and the funds are not in place in time, the contractor's investment in order to reduce costs and reduce the investment, as well as the fluke psychology, will also affect the construction.

　　5) Factors related to supervision and owners. If the relevant management personnel have insufficient professional knowledge and poor management capabilities, blindly command and take risks during the construction process, it will also affect the construction.

2. Evaluation of risk

The geological and soil layers along the pipeline change frequently, so understand the changes of the geological and soil layers before the pipe jacking machine. In addition, the soft foundations, karst caves and other sections to be passed through need to be treated in advance to prevent excessive surface subsidence from causing roads. Collapse. At the same time, when crossing the river, the overburden and the geology of the bottom of the river bed should be ascertained, and the elevation during jacking should be controlled to prevent the influx of river water due to the breakthrough of the soil layer.
