- Abstract
Three - dimensional laser scanning technology plays an important role in the water conservancy industry with its high precision and fast speed. In order to clear the deviation between the actual surface shape, size and design value of the flow channel after the reconstruction of Siyang second station, the shape and size of the inlet flow channel after the reconstruction of Siyang second station were detected based on the three - dimensional laser scanning technology, and the cross -sectional size and design size were compared and analyzed. The results show that the construction size deviation control of the concrete flow channel reconstruction project is generally good and meets the design requirements. The flatness deviation of the inner wall surface of the flow channel within the construction area is generally within the range of ± 1. 4 mm. The size deviation of the control section with a small degree of transformation after construction is generally within ±10 mm;after the completion of the construction of the control section with a large degree of transformation, the size deviation value is within ± 20 mm. The field measurement results provide a reference for the construction quality evaluation of the flow channel of Siyang second station, and also provide a basis for the construction accuracy of the flow channel of the pumping station.
