A rapid positioning method and inspection and measurement method for inclined piles on water

Abstract

The invention discloses a rapid positioning method for overwater oblique piles and an examination and measuring method thereof, belonging to the field of positioning measurement. The rapid positioning method comprises the following steps: determining piling positions, which are intersection points of the oblique piles and the spatial straight line of the center axis of a pile driving barge; ensuring superposition of the centering direction of the pile driving barge and the projection directions of the oblique piles; determining the spatial straight line of the center axis of the pile driving barge by using GPS RTK or network RTK technology; and measuring the elevation of the pile driving barge during GPS RTK measurement, calculating the coordinates of lofting points according to the designed coordinates and elevations of the piles and the horizontal torsional angles and inclination angles of the piles, finding out the central position of the piles, anchoring the fore of the pile driving barge, and then allowing the stern of the pile driving barge to swing so as to enable the orientation of the pile driving barge to be identical to the swing angle of the piles in row, thereby finishing positioning and orienting. The rapid positioning method provided by the invention can rapidly determine the spatial straight line L2 of the center axis of the pile driving barge, so a construction base line is omitted; the rapid positioning method has an error in a range of 15 to 25 mm; and the rapid positioning method is of critical significance to construction quality control and construction speed acceleration.

Description

technical field [0001] The invention belongs to the technical field of positioning and measurement, and in particular relates to a rapid positioning method and a testing and measuring method for inclined piles on water. Background technique [0002] In the construction of port and shipping terminals, there are often island embankment constructions, which use piling ships to drive inclined piles on the water, and use inclined piles to bear horizontal loads. According to the construction regulations of port and shipping terminals, the construction error of inclined piles should not be greater than 10cm, and the measurement positioning error is about 3cm. Water operations are much more complicated than land operations, which imposes stricter requirements on measurement technology. In the construction of port and shipping terminals, there are often high-pile wharf constructions. This type of construction is not on the shore, but pilings are driven on the water by piling boats. ...

AI Technical Summary

Problems solved by technology

[0003] To sum up, the problems existing in the existing technology are: there is a construction baseline in the positioning measurement of inclined piles on the water, and the distance between the construction baseline and the construction ship is too far to be inconvenient to control, the visibility is blocked, and the command and coordination are difficult.
