The first steel sleeve 2 is operated to slowly start the oil injector and control the air flow, a light hammer is adopted to slowly advance to prevent the steel sleeve 2 and the pipe ramming hammer 11 from reciprocating and moving together, the steel sleeve 2 is rammed into the soil layer by 30-50cm, the hammer is stopped to check the position of the steel sleeve 2, after the steel sleeve is errorless, the light hammer is continuously rammed into the soil layer for 2-3m, the position of the steel sleeve 2 is checked again, the first steel sleeve is rammed into the soil layer continuously in a light hammer slow advancing mode, and an infrared horizon instrument is adopted to control the direction parameters in the jacking process to ensure that the jacking direction does not deviate from the central line.
According to the parameters of the tamping pipe, the front end of the first section of steel sleeve 2 always keeps 2-3m of soil column to ensure that the soil layer at the front end of the cutting ring 13 can enter the steel sleeve 2 after being extruded, thereby ensuring the advancing direction of the steel sleeve 2 and protecting the road from uplifting or sinking.
Since the accuracy of the ramming direction of the first section of steel casing 2 is most critical, the direction of the steel casing 2 should be carefully measured from the horizontal after the first section of steel casing 2 is rammed 500mm, with an angular deviation of no more than 0.5 degrees. And if the deviation of the axis does not exceed 1% of the tamping length, continuing tamping, and if the deviation of the axis exceeds an allowable range, correcting the deviation, namely manually clearing soil around the steel casing 2 in the direction opposite to the deviation of the axis, wedging the outer wall of the steel casing 2 in the direction of the deviation of the axis, and adjusting the deviation of the axis of the casing to the allowable range to continue tamping. The rail deviation can be corrected by adjusting the rail base.
