Water plastic drainage board engineering ship set ship positioning system, power system, winch system,PVDPlate insertion system and construction automation control system and other high-end technologies in one, belongs to high technology, high added value of major technical equipment, is dedicated to major offshore projects(High technology equipment for reclamation projects, seaports, cross-sea Bridges, maritime airports, Marine garbage dumps, etc.)
Plastic water drain boardBy the seaPVDThe ship is completed, PVDThe ship has a whole-course intelligent monitoring system, which can monitor the construction data in real time.Specific operation methods are as follows:
1,Mobile working ship
usingGPSPosition, tow the working ship to the working destination, and shadow the set coordinate geometry and the moving coordinate geometry.
2,Drainage sheet pile positioning
The longitudinal and transverse rails on the hull are used to control the movement of the pile frame, and the allowable error is100mm.
3,The ship positioning
throughGPSAfter determining the construction position of the working ship, use the traction boat to stop the working ship to the correct position, and drop the fixed anchor to fix the working ship. Each ship has four fixed anchors, and the fixed anchors fix the drainage plate behind the working ship.
4,The pile machine positioning
The slotting machine goes throughGPSAfter determining each construction pile position, the drainage plate pile position can be accurately positioned before installation. Install post boots on the tip of each plastic drain plate before insertion. It begins to pass through the sea water, penetrate the sand cushion, reach the silt layer, and reach the hard soil layer determined by the change of current value.
5,The drainage board is inserted
According to the special technical specifications, it is determined to reach below the hard soil layer0.5mAfter that, begin to pull out the casing. When pulling out the casing, the pile boots hold the plastic drainage plate at the tip of the pile to avoid pulling out with the casing.
6,Underwater cutting board
A certain distance after the casing is pulled out of the sand cushion,Drop the drain shears and cut under water.
7,complete
After all the pile positions on the working ship are completed, the four anchors of the ship are used to move the working ship to the next construction position.
