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

Abstract

The invention discloses a light long-distance cross-sea intelligent permanent railway and highway floating bridge with a low manufacturing cost and a short construction period, which fundamentally changes the design thought of building cross-sea bridges. The biggest problem is solved, piers do not need to be built on the strait seabed, the construction difficulty and work amount of building a 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 held by a seabed rooted stainless steel wire rope, the floating islands are synthesized by cheap materials, and bridges are erected on the floating islands; 2, a special well hole is drilled in the bottom of the strait seabed, a stainless steel wire rope is pre-embedded in a sleeve for mud sealing, and under the conditions of seabed geology and local typhoon intensity, the stainless steel wire rope can also be wound and tied on a reinforced concrete block sinking into the seabed to replace a well drilling hole; and 3, 12-strand rooted stainless steel wire ropes are evenly distributed on the left side and the right side of the floating island and tightly grasp the floating island, the absolute horizontal height of the floating island is not changed, and at the lowest tide level, it is ensured that the 12-strand rooted stainless steel wire ropes have moderate tension.

Description

1. Technical field [0001] Cross-sea bridge design 2. Background technology [0002] 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. [0003] 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. [0004] 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. [0005] The location of the constructi...

AI Technical Summary

Problems solved by technology

[0007] 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 quantity 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.
