Embodiment Construction
[0012] refer to figure 1 As shown, the present embodiment is first according to the formula Calculate the horizontal distance deviation value between the outer edge of the flap of the laying ship in the horizontal state and the state lowered to a predetermined angle. Among them: c is the horizontal distance deviation value between the outer edge of the laying ship flap in the horizontal state and the state of lowering to a predetermined angle, a is the width of the laying ship flap, h is the outer edge of the laying ship flap in the horizontal state and lowered to a predetermined angle. The height difference between the predetermined angle states; then according to the calculated horizontal distance deviation value c, when the laying ship entry point is positioned, on the basis of the original set position, translate to the direction of the outer edge of the laying ship flap with the same value as c distance.
[0013] In this way, the effects of eliminating deviation, impro...

The invention discloses a method for improving the laying construction precision of a geotextile-laying vessel. The method for improving the laying construction precision of the geotextile-laying vessel comprises the steps that the horizontal distance deviation value of the outer edge of a turning plate of the geotextile-laying vessel in the horizontal state and at a preset angle is calculated according to a formula (please see the specification for the formula), wherein c is the horizontal distance deviation value of the outer edge of the turning plate of the geotextile-laying vessel in the horizontal state and at the preset angle, a is the width of the turning plate of the geotextile-laying vessel, and h is the height difference of the outer edge of the turning plate of the geotextile-laying vessel in the horizontal state and at the preset angle; and according to the horizontal distance deviation value obtained through calculation, during feed-point positioning of the geotextile-laying vessel, the geotextile-laying vessel is moved horizontally towards the outer edge of the turning plate of the geotextile-laying vessel by the distance of c from an originally set position. In thisway, deviation is eliminated, the sinking position precision of a mattress body of a soft body mattress is improved, and the laying construction quality of the soft body mattress is improved.
Description
technical field [0001] The present application relates to the technical field of laying ship laying construction, in particular to a method for improving the construction accuracy of laying ship laying. Background technique [0002] At present, in domestic embankment projects, port projects, and river channel projects, laying boats are mostly used to lay soft row bottom protection construction. During laying construction, firstly, the entry point of the laying ship is positioned, and then the splicing of different types of rows, sand rib binding, rolling and other processes are carried out on the deck of the laying ship (according to design requirements). After the completion, slowly lower the flap to lift the steel cable, make the flap rotate downward at a certain angle according to the rotation point, start the roller, and make the front part of the row head slowly slide into the water under its own gravity until it sinks to the bottom. However, there is a certain horizon...
