When the pile driver is pouring the pile, how to calculate the buried depth of the pile pipe?

First, the initial length of the filling pipe is reduced by 0.5 to 0.8 meters from the bottom of the hopper to the bottom of the pile. Calculating the depth of the buried pipe can be used to draw an elevation view of the conduit. The elevation of the upper mouth is the elevation at the connection. The elevation of the concrete, the elevation of the lower mouth is the elevation of the junction-the total length of the pipe. When painting, draw in the order of the reverse pipe, that is, the upper pipe is drawn below. For example, if the pipe section from top to bottom is 1m + 3m + 6m + 6m + 6m, it will be drawn from top to bottom 6m + 6m + 6m + 3m + 1m,

2. After the first pouring of concrete into the hole, the cast-in-place pile pipe should be buried in the concrete no less than 0.5 meters, and some specifications are larger.

After filling concrete in the future, measure the distance L from the concrete liquid level to the pipe connection mouth with a measuring rope, etc., you can draw the position of the concrete on the above picture, and you can read the buried depth of the catheter at this time. The calculation test is: buried depth = total length of the pipe-the distance L from the concrete level to the pipe mouth. The catheter was buried too far, so a section of the tube had to be folded. The selected section is the above section, such as the 1 meter section mentioned above, because the picture is drawn in reverse. So tick off the 1 meter section below. Do you know why you want to draw in reverse? Similarly, after pouring the concrete, measure the distance L from the liquid level of the concrete to the nozzle. The position of the concrete can be drawn on the map, and the buried depth of the grouting pipe can be read from the map.
