Light long-distance sea-crossing intelligent permanent railway and highway floating bridge low in manufacturing cost and short in construction period

Abstract

The invention provides a light long-distance sea-crossing intelligent permanent railway and highway floating bridge low in manufacturing cost and short in construction period, and the design thought for building a sea-crossing bridge is fundamentally changed. The biggest problem is solved, piers do not need to be built on the strait seabed, the construction difficulty and the engineering quantityfor building the cross-sea bridge are greatly reduced, and the influence on the strait ecological environment is small. The technical key points are as follows: 1 floating islands are built by utilizing seawater buoyancy, each floating island is firmly grasped by a seabed rooting stainless steel wire rope, the floating islands are synthesized by cheap materials, and bridges are erected on the floating islands; 2 the seabed rooting stainless steel wire rope of the floating pier is tied and pulled, a movable self-elevating offshore oil drilling platform low in relative cost is used for drillingspecial well holes in the bottom of a strait seabed, each hole comprises a vertical rock well hole body and a horizontal well hole body, and a stainless steel wire rope is embedded in a casing pipe for mud sealing; and 3 in order to reduce the excessive tension of the rising force of the floating islands on the stainless steel wire ropes during rising tide, the equipment for tying the stainless steel wire ropes on the floating islands is an intelligent control electric winch; and 4 the intelligent land bridge head trestle and the bridge are synchronously adjusted.

Description

[0001] 1. Technical field [0002] Cross-sea bridge design. [0003] 2. Background technology [0004] The most important and most difficult part of building a cross-sea bridge is the construction of piers. The traditional design requires pile foundations to be laid on the seabed. [0005] The "floating caisson method" is often used to drive the prefabricated piles to a specific position by a professional piling ship, and then add reinforced concrete to the inside after the water is drained to fix the pile foundation in the water. After the pile foundation is laid, what needs to be done is the overall load-bearing and anti-corrosion considerations. [0006] There is also a "caisson construction method" invented by Mao Yisheng. First, a cylindrical barrel is sunk, and then concrete is poured into the barrel. When the concrete in the barrel reaches a certain weight, the cylindrical barrel is naturally sunk, and then stabilized. at the bottom of the sea. [0007] The location o...
