Abstract
The invention discloses an underwater tunnel-bridge and relates to an underwater passage. The underwater tunnel-bridge consists of a bridge pier, a reinforced concrete deck beam, tunnels, a helmet shield, a secondary channel and a water service road. The tunnels are arranged in parallel on the reinforced concrete deck beam, the shell of each tunnel is covered with the reinforced concrete helmet shield; and the tunnels are provided with the secondary channel which is stretched out of the water face and connected with the water service road, and the water service road is supported by the bridge pier. The invention concisely provides a basic method for building a stable and firm railway close to the water face in a water area with a deep rock layer and high requirement on a navigation pure height so as to well solve a plurality of problems; the tunnel is built by using buoyancy of water, and sand stone is fully used for protecting the tunnel-bridge and absorbing the vibration when a vehicle passes; and the basic method can be used for building stable and firm passages of railways and highways at the downstream of the Yangtze River and similar water areas, and building tunnels close to the water face in a deep water areas.
Description
Technical field
The present invention relates to passage in a kind of water, belong to the bridge construction technical field.
Background technology
In THE LOWER YANGTZE VALLEY with similar rock stratum is dark, the water surface is wide, especially big suspension bridge, cable stayed bridge and even composite bridge are built in navigation clear height big waters, the technology that is used to solve highway communication all possesses.But lead to railway, build the steel structure bridge in similar Wuhu, then certainly will stand in great numbers by bridge pier, be bound to access bridge length, bridge pier Gao Ershen certainly will make the navigation channel seriously limited.If build golden waterway in, its influence to water transport is well imagined.If go deep into the rock stratum built tunnel, then dark nearly hundred meters, even surpass hundred meters, too dark again.If it is built tunnel passes through the alluvium, then difficult again steady.
Summary of the invention
The present invention is directed to the problems referred to above and demand, propose a kind of both more shallow alluvium of in water, passing through, can base oneself upon the organic assembling body in tunnel and bridge in the water of the anti-depression in rock stratum again as the bridge pier that stands in great numbers.
Technical scheme of the present invention is: the present invention is made up of bridge pier, reinforced concrete bridge deck beam, tunnel, helmet cover, subaisle and sidewalk waterborne, tunnel arranged side by side is arranged on the reinforced concrete bridge deck beam, cover steel concrete helmet cover above the shell in tunnel, the tunnel is provided with emersed subaisle, subaisle is connected with sidewalk waterborne, and sidewalk waterborne is supported by bridge pier.
The tunnel lowest part is located under water apart from the above depths of water surface 20m.
Described reinforced concrete bridge deck beam is provided with the circular groove suitable with tunnel bottom, and cross section is pen carriage shape.
The reinforced concrete bridge deck soffit is level and smooth, circular arc is established in itself and confluce, two sides, the bridge floor beam inner hollow, closed at both ends, load when sinking to fall greatly, the length that bridge floor beam is every section is 2 times of bridge pier spacing, and the middle part, two ends of every section bridge floor beam all rests on the corresponding bridge pier, and the both sides of every section bridge floor beam are provided with lifts bail.
Bridge pier of the present invention is by bearing platform and spacing bridge pier two parts are formed under water, be positioned at the following bridge pier in bridge floor beam bottom and be bearing platform under water, every platform be a cross section be fusiformis monolithic construction, also can be character, be positioned at the bridge floor beam both sides on the platform and have emersed spacing bridge pier, the cross-sectional area of spacing bridge pier is less than 1/2 of bearing platform.
Described spacing bridge pier restriction tunnel, helmet cover and and the position of subaisle, and the supporting basis of double as sidewalk waterborne.
The spacing bridge pier middle part that is positioned on the navigation channel is provided with articulated elements, can have a down dip by saving it on by control device waterborne, and it saves up and down also to can be and removably connects, save the junction up and down and be located under water, with the distance of the water surface greater than the specified navigation degree of depth.
The proposition that the present invention is simple and clear dark in the rock stratum; the basic skills that dried up nearer steady real railway passage built in the big waters of navigation clear height demand; more satisfactory solution relevant many difficult problems; the present invention not only uses buoyancy of water to set up the tunnel; and sandstone have been made full use of to the protective effect of tunnel bridge with the cushioning effect when being open to traffic; basic skills of the present invention can apply to THE LOWER YANGTZE VALLEY and railway, the steady real channel of highway are built in similar waters, also can apply in dried up nearer tunnel of construction, profundal zone.
