Problems solved by technology

[0010] It solves the biggest problem. It does not need to build bridge piers on the seabed of the strait, which greatly reduces the construction difficulty and engineering volume of the construction of the cross-sea bridge, shortens the construction period, reduces investment, has little impact on the ecological environment of the strait, and is green and environmentally friendly.

Embodiment Construction

[0024] Use the buoyancy of seawater to build floating islands. Each floating island is held firmly by stainless steel wire ropes rooted on the seabed. The floating islands can be made of cheap corrosion-resistant materials, and bridges are built on the floating islands. Attached picture

[0025] 1. Tie the seabed rooting stainless steel wire rope of the floating island

[0026] (1) N pontoon piers, namely floating islands, are uniformly pre-designed and arranged along the width direction of the strait.

[0027] (2) Using a relatively low-cost mobile jack-up offshore oil drilling platform, drill 6 special wells DN140 with uniform and symmetrical distances on the seabed below the left and right sides of each floating island (the depth of the wells is based on The depth of seawater and the thickness of seabed silt, for example, the Qiongzhou Strait is about 100 meters deep), and the well spacing is determined according to the size of the floating island. The cost of drilling ho...

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...
