1. Seabed rooting stainless steel wire rope bound to and pulled from floating island

(1) N floating piers, namely floating islands, are uniformly pre-designed and distributed along the width direction of the strait.

(2) And by utilizing a movable self-elevating offshore oil drilling platform with relatively low cost, respectively drilling 6 special well holes DN140 with uniform and symmetrical distances on the seabed below the left side and the right side of each floating island (the well hole depth is determined according to the sea water depth and the seabed silt thickness, such as about 100 meters deep in the Johnson state channel), and the well hole distance is determined according to the size of the floating island. The cost of the drilling hole accounts for about 50 percent of the total manufacturing cost of the bridge.

(3) And the vertical depth of each well hole below the seabed is respectively 200 meters, 220 meters, 240 meters, 230 meters, 210 meters and 190 meters (the specific depth is according to the thickness of silt and the thickness of rock and the required generated tension, the depth is different in order to prevent horizontal wells from mutually crossing and colliding) + 60 meters of horizontal wells in the depth of the rock (the specific depth is according to the properties of the rock and the required generated tension), and the outer wall of an oil casing DN140 (general purpose 5.5 inches) in each well hole is cemented by mud (the conventional method).

(4) The built-in stainless steel wire rope of oil casing is closely knit with mud shut-in well, and one strand is reserved promptly for the bifilar for every strand of stainless steel wire rope, and the stainless steel wire rope designs the monitoring return circuit that opens circuit simultaneously, and stainless steel wire rope is used for tying up and draws the chinampa, considers adopting 316 stainless steel wire rope, also can adopt the rope of other corrosion-resistant and firm materials.

(5) And the stainless steel wire ropes bound and pulled from the seabed bottom to the sea surface and to the floating island are well subjected to corrosion prevention and surface smoothing treatment, seawater corrosion and marine organism adhesion are reduced, and warning marks are made to prevent the collision between ships and marine organisms.

(6) And the design of the tension of the stainless steel wire rope considers that the floating island can resist 18-grade typhoon.

2. Floating island

(solving the wave force and wind lifting force in the following detailed description)

(2) The floating island is formed by hollow synthesis of waste tire powder (or a durable hollow polyethylene plastic floating body, or a closed steel floating cabin exterior chrome-plated or a closed aluminum bronze floating cabin), and the length, width and height of the floating island are designed according to the basic principle that the buoyancy of N floating piers can bear the weight of a bridge and the load of a bridge deck and ensure the stability of the floating island (for example, the length is 30m multiplied by 20m multiplied by the height, and the height higher than the sea surface is determined according to the height of the bridge and the resistance to typhoon). The floating island is required to resist seawater corrosion, and is required to be periodically checked for corrosion prevention and surface smoothing treatment, so that seawater corrosion and marine organism adhesion are reduced, and warning marks are made to prevent collision between ships and marine organisms.
