Method for measuring deviation of jacking direction of single-hole pipe culvert

The invention relates to a method for measuring a deviation of a jacking direction of a single-hole pipe culvert. The method comprises the following steps: respectively arranging a theodolite at each of positions, adjacent to the back of an inner wall of the pipe culvert, of two sides of the pipe culvert, so that an infrared ray emitted by the theodolite is close to the inner wall of the pipe culvert and is disposed at a same elevation with the center of the pipe culvert; respectively forming a vertical rectangular slot at the centers of two sides of the inner wall of each section of pipe culvert; producing a scale plate, wherein the scale plate is provided with grids; when a pickaxe is jacked, inserting, by the measurement personnel, one end of the scale plate into the slot, so that the infrared ray emitted by the theodolite radiates on the scale plate, and reading, by the measurement personnel, the jacking deviation of the pipe culvert according to the position of a radiation point of the infrared ray emitted by the theodolite on the scale plate. The method has the advantages of simplicity and convenience in operation, the measurement precision is high, the used measurement apparatus is reused, and the waste is avoided.
