Various safety measures must be implemented during the construction of precast concrete components

For different construction projects during construction, such as hoisting projects, production of working caissons, and temporary power use on site, special safety construction plans, hoisting construction plans, temporary power use construction plans, etc. must be formulated in accordance with the requirements of laws and regulations. Various safety measures must be implemented during the construction process.

The geological soil layer changes frequently along the pipeline, so it is necessary to understand the changes in the geological soil layer before pipe jacking construction. In addition, the soft foundation, karst caves and other areas to be passed need to be processed in advance to prevent excessive subsidence of the ground surface causing road collapse. At the same time, when crossing a river, it is necessary to ascertain the covering soil and geological conditions at the bottom of the river bed, and control the elevation during jacking to prevent the influx of river water due to the breakthrough of the soil layer.

The stratum of concrete prefabricated components in pipe jacking construction generally passes through the silt layer. 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 depth of the pipe jacking well and the 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 the pipe to ensure that workers inside the pipe have enough fresh air.

The technical level and safe operation ability of various personnel will affect the safety of pipe jacking construction, so personnel must be evaluated. Whether the safety performance of the equipment is adequate and meets the standards, the safety risks that exist must also be evaluated.

Whether safety rules and regulations, operating procedures are sound, and whether safety education and training are in place will all have an impact on safety management, so they should be evaluated to discover management deficiencies and flaws.

Safety risk control during pipe jacking construction includes all various measures taken to avoid or reduce the possibility of safety risks and potential losses. General countermeasures and measures to control security risks include: mitigation, prevention, transfer, avoidance, retention, diversification, backup measures and utilization, etc.

During the pipe jacking construction process, units and relevant responsible persons who fail to implement safety technical measures and create major accident risks or cause accidents must be dealt with seriously, and there must be no loss of control in terms of safety. If safety management is in place and those who meet the requirements are rewarded heavily, an effective safety management mechanism will be formed, the consciousness will change from "I want safety" to "I want safety", an atmosphere in which everyone is responsible for safety production will be formed, and everyone will be motivated to participate in safety management.
