Underwater immersed tube positioning method
The invention discloses an underwater immersed tube positioning method, and mainly relates to the technical field of underwater immersed tube positioning. Comprising the following steps: manufacturing an immersed tube with elevation scale marks on the outer wall; two coordinate points are determined on the front side of the immersed tube mounting position, the mounting position of a positioning light target is determined on the rear side, and values of a and beta are determined; arranging a known coordinate point I and a known coordinate point II on a construction site by using a total station, and positioning the position of a light target; arranging a laser emitter and a positioning light target; the two laser emitters are adjusted according to the angles a and beta; hoisting the immersed tube, and accurately positioning the position of the immersed tube according to the principle that laser light is tangent to the immersed tube; sinking the immersed tube; measuring elevation scale marks on the immersed tube by using a level gauge in the sinking process of the immersed tube; and sinking the pipe in place. Real-time positioning and deviation rectification in the pipe sinking process can be achieved, meanwhile, the elevation of the sinking pipe is accurately measured through the scale marks on the sinking pipe, and therefore real-time accurate positioning and elevation control of coordinates of the sinking pipe are achieved, and operation is convenient.
