With respect to the skids 5, the skids 5 are arranged on the spread ship hull 1 in a turned-over manner and extend to the outside of the spread ship hull 1 at a downward inclination angle after the skids 5 are turned over, which facilitates the roll arrangement to slide down and drop into the water.
Regarding the RTK measuring instrument 8, the RTK measuring instrument 8 is a high-precision split RTK, the RTK measuring instrument 8 is arranged on the top of the cockpit 9 and is fixed through a fixing bracket, and a positioning control instrument is arranged in the cockpit 9 and is connected with the RTK measuring instrument 8 through a communication electric wire.
In summary, the auxiliary device for paving the sand rib soft mattress under the deepwater condition mainly comprises: 1000 ton level spread ship body, 2 10 tons of cranes 2, 2 RTK measuring instruments 8, winding drums 3, guide beams 4, dynamic control of sonar scanning equipment, sliding plates 5, an electrical system 10, a cockpit 9 of a spread positioning control instrument and the like.
Taking the engineering of the applicant as an example, the engineering adopts a sand rib soft row facing with the thickness of 30cm, the width of 39m and the length of 45m. And (5) adopting a 1000-ton-level spreading ship to finish the sand rib soft raft spreading operation.
Firstly, positioning a laying ship: before construction, relevant laying parameters are input by a constructor according to the design, a sand rib soft row framing chart of a construction area is imported, operators in a control room retract and release anchor position steel wire ropes according to framing blocks in positioning software, a laying ship is moved to a starting position, and when a computer displays a deviation value and a displacement value within an allowable error range, the fact that the construction ship reaches the design position is indicated. And finally, anchoring and fixing the row-laying ship by using an anchor boat. The included angle between the anchor position and the laying direction is not too large during anchoring, and the anchor position cannot be thrown on the laid soft mattress.
And (3) coil arrangement: after the row is transported to the site by the transport ship, the laying ship places the slide plate 5 horizontally, and the row is hoisted to the deck by the ship crane 2. The row body is unfolded on the deck, the brake is released, and the reinforced ring at the tail end of the row body is connected with the steel wire ropes arranged at each point on the winding drum 3 by using the double strands of polypropylene ropes.
The connection mode of the row body and the winding drum 3 is as follows: a hanging nose is arranged on each meter of the winding drum 3, 4-branch steel wire ropes are connected with the winding drum 3, two galvanized rings are arranged at the tail ends of the steel wire ropes, the hanging nose is welded on the two galvanized rings corresponding to the steel wire ropes, and the steel wire ropes are connected with the hanging nose through clamping rings. The geotextile is connected with the galvanized ring through an upper pair of nylon ropes, one ends of the nylon ropes are fixedly tied on the galvanized ring corresponding to the positions of the steel ropes, and the other ends of the nylon ropes penetrate through a soft bar reinforced belt buckle Kong Hui to be tied on the galvanized ring, and a slipknot is made.
Starting an electric winch at the end part of the winding drum 3, winding up polypropylene ropes, arranging one worker for every two ropes so as to correct rope positions at any time, avoiding rolling deflection and wrinkling, arranging 6 workers on two sides of the upper row body of the deck, leveling, lifting and arranging the body, and stopping the operation of the winding drum 3 when the front end of the row body is level with the edge of the sliding plate 5.
And (5) moving the ship, laying sand ribs and filling: the paving is carried out on a special paving ship, and the whole soft paving process advances from downstream to upstream along the axial direction of the embankment body.
After the sand carrier enters the gear, the crane 2 hangs the slurry pump 22kw into the proper position on the sand carrier, and the sand ribs are penetrated at the same time of the ship entering the gear. Starting a high-pressure water gun to flush water into a sand cabin, starting a slurry pump to fill sand ribs after sand water around the slurry pump is mixed, controlling the concentration of mortar in the filling process, and filling clear water before stopping filling so as to prevent pipe blockage. When filling, the 14# lead wire is used for screwing the cuffs of the sand rib bags on the shunt ports of the sand conveying pipes, and the valve of the shunt ports is opened for filling. The sand ribs are stepped on by manpower in the filling process, so that the sand flow is smooth. Filling sand ribs from one end, filling in a staggered way, strictly prohibiting bidirectional opposite filling, and controlling the filling rate of the sand ribs to be not less than 75-80%.
After filling a plurality of sand ribs, putting down the turning plate to form 40 degrees with the horizontal plane, starting the winding drum 3 to control the motor, at the moment, under the action of the dead weight of the sand ribs, slowly sinking the discharging body along the turning plate, slowly moving the ship position when the discharging body enters water to reach the mud surface and has a certain surplus length, so that the filled sand rib soft body is slowly laid, and immediately braking the winding drum 3 when the filled sand ribs completely slide onto the deck. And continuing to penetrate and fill the deck sand ribs, repeating the steps, and determining the ship moving distance according to the water depth, the length of the underwater row body and the discharging width. In the discharging process, a measuring person rectifies and commands the moving anchor and dynamically controls the discharging body sinking to ensure the laying quality of the sand rib soft mattress.
