What should we generally pay attention to in the stratum during pipe jacking construction?

The stratum used for pipe jacking construction generally passes through the silt layer, and decaying animals and plants will form toxic and harmful gas aggregates underground. If toxic and harmful gases are not detected during pipe jacking construction, and ventilation and other measures are not taken, construction workers are prone to poisoning accidents in such a working environment, endangering the health and lives of construction workers.

During pipe jacking construction, management personnel's illegal instructions and operators' illegal operations, such as risky or wild construction, new workers taking up the job without safety education and training, special operators holding special operation certificates without special safety training, etc., are all potential risk factors that cause safety accidents in pipe jacking construction.

Safety risk management in pipe jacking construction is a general term for the entire process of analyzing safety risks in pipe jacking construction through risk identification, risk estimation and risk evaluation, and based on this, using a variety of methods and means to effectively control the safety risks involved in pipe jacking construction, maximize the beneficial results of safety risk events, and properly handle the adverse consequences of safety risk events. It includes several stages such as security risk identification, security risk assessment and security risk control.

1) Factors in hydrogeology and engineering geology. The geological soil layer where pipe jacking is constructed changes frequently. If the hydrogeological data is not accurately grasped before the start of construction, construction accidents will occur.

2) Construction factors. The selection of construction methods, the selection of construction equipment, the allocation of personnel and the quality level of personnel will all affect construction safety.

3) Factors related to supervision and owners. If the relevant management personnel have insufficient professional knowledge and poor management capabilities, and blindly direct and take risks during the construction process, construction safety will also be affected.

4) Design influencing factors. The reliability, scientificity and pertinence of the design plan will also affect the safety of the construction process.

5) Economic influencing 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 received in time, the contractor will reduce investment in safety in order to reduce costs, and have a sense of luck, etc., which will also affect construction safety.

The stratum during pipe jacking construction generally passes through the silt layer, and decaying animals and plants will form toxic gas aggregates underground, endangering the health and lives of construction workers. At the same time, due to the deep pipe jacking well and long jacking distance, there is a lack of oxygen in the pipe, and people are easily suffocated when working inside. Therefore, when someone is operating in the pipe, it is necessary to regularly monitor the content of toxic gases in the pipe, and ventilate the well and inside the pipe to ensure that workers inside the pipe have enough fresh air.
