[0046] Casing connection and deviation correction: when connecting multiple sections of casing, V-shaped groove three-pass welding process is adopted, the groove angle is 60°, the weld reinforcement is 2mm high, and stress concentration is eliminated by polishing after welding, and ultrasonic flaw detection is used to detect the integrity of the weld; every 2-3 meters of ramming is checked to correct the deviation in time, ensuring the construction accuracy;

[0047] Construction completion: repeat the steps of ramming, soil cleaning and grouting, and continue to work until the casing penetrates the boulder layer and enters the bedrock 30 meters, completes the ramming pipe construction in the boulder area, uses a gas detector to monitor harmful gases in the sealed space throughout the construction process to ensure the safety of construction personnel; every 0.5 meters of ramming is reviewed to ensure that the deviation is less than or equal to 1.5% of the pipe diameter, ensuring construction quality; emergency water pumps and generators are set up to effectively control the underground water level and prevent the impact of underground water problems on construction safety and quality.
