Abstract

The utility model aims to provide an undersea tunnel bridge which comprises shore-based transition tunnels, a hanging and floating tunnel bridge cylinder and bridge piers, wherein the hanging and floating tunnel bridge cylinder is arranged under the sea; the bridge piers are uniformly fixed at the sea floor in the axial direction of the hanging and floating tunnel bridge cylinder; the hanging and floating tunnel bridge cylinder is fixed on the bridge piers through fixed holes, rings or pile foundations; and the shored-based transition tunnels comprise a first shored-based transition tunnel and a second shored-based transition tunnel, and the first shored-based transition tunnel and the second shored-based transition tunnel are arranged under shores at two ends of the hanging and floating tunnel bridge cylinder respectively and connected with the two ends of the hanging and floating tunnel bridge cylinder. The undersea tunnel bridge is defined between a cross-sea bridge and an undersea tunnel, overcomes shortcomings by learning from strong points of the cross-sea bridge and the undersea tunnel, integrates advantages of the cross-sea bridge and the undersea tunnel, overcomes defects of the cross-sea bridge and the undersea tunnel, and has the characteristics of reasonable design, environmental protection, energy saving, safety, reliability, wide applicable range, convenience in construction and the like.

Description

The lower tunnel bridge in sea
Technical field
The utility model relates to a kind of tunnel, specifically lower tunnel, sea.
Background technology
Land communications over strait under prior art mainly realize by bridge formation over strait and cutting tunnel, seabed, and these two kinds of modes all exist many deficiencies.The climatic factor impacts such as the easy wind-engaging of bridge spanning the sea, mist, rain, snow, unimpeded when being difficult to whole day, though seabed tunnel can be realized round-the-clock current, but in marine site, cross dark or meet in the situations such as trench and seabottom geology complexity, often cause transition tunnel long, difficulty reality excessive or that may not build, at present, the solution also not had.
Summary of the invention
The purpose of this utility model is to provide and can realizes tunnel bridge under sea over strait.
The purpose of this utility model is achieved in that
Tunnel bridge under the utility model sea, it is characterized in that: comprise the excessive tunnel of bank base, hang floating tunnel bridge cylinder, bridge pier, hanging floating tunnel bridge cylinder is arranged under sea, between bridge pier, along hanging floating tunnel bridge cylinder, axially evenly arrange and be all fixed on seabed, hanging floating tunnel bridge cylinder is fixed on bridge pier by fixing hole, ring or pile foundation, the described excessive tunnel of bank base comprises the first excessive tunnel of bank base and the second excessive tunnel of bank base, and the first excessive tunnel of bank base is separately positioned under the seashore that hangs floating tunnel bridge cylinder two ends and respectively and is connected with the two ends of hanging floating tunnel bridge cylinder with the second excessive tunnel of bank base.
The utility model can also comprise:
The cross section of 1, hanging floating tunnel bridge cylinder is for circular, oval or square.
Advantage of the present utility model is: the utility model, between bridge spanning the sea and seabed tunnel, is learnt from other's strong points to offset one's weaknesses, and has both advantages concurrently and avoids inferior position separately, have reasonable in design, environmental protection and energy saving, safe and reliable, wide accommodation, builds the features such as convenient.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, for example the utility model is described in more detail:
In conjunction with Fig. 1, the utility model is by the excessive tunnel 1 of bank base, bridge pier 2 and hangs floating tunnel bridge cylinder 3 and form, build bank base transition tunnel 1 for 9 times to entering extra large interface 4 under water building across relative two seashores of seabed tunnel, at precalculated position bridge construction pier 2 to predetermined altitude, hanging floating tunnel bridge cylinder 3 merogenesis makes, haul to desired location with himself buoyancy at shutoff two ends, more piece sinks to following precalculated position, sea 10 after connecting, and be fixed on bridge pier 2 or butt up against tunnel and enter extra large interface 4, after abutting joint, connect whole tunnel omnidistance.
While hanging floating tunnel bridge cylinder 3 through shoal, can adopt trench digging bridge cylinder shallow embedding 5 modes to process, during through trench 13, can adopt anchor chain 6 modes to be fixed on trench 13 bottoms, during through island 11, can dig tunnel, by bank base transition tunnel 1 mode, process, on Ye Ke island, build way station 7, during through submerged reef 14, can replace bridge pier 2 and pass through, also can build thereon service station 8 open and sealing.

Claims (2)

1. tunnel bridge is descended in sea, it is characterized in that: comprise the excessive tunnel of bank base, hang floating tunnel bridge cylinder, bridge pier, hanging floating tunnel bridge cylinder is arranged under sea, between bridge pier, along hanging floating tunnel bridge cylinder, axially evenly arrange and be all fixed on seabed, hanging floating tunnel bridge cylinder is fixed on bridge pier by fixing hole, ring or pile foundation, the described excessive tunnel of bank base comprises the first excessive tunnel of bank base and the second excessive tunnel of bank base, and the first excessive tunnel of bank base is separately positioned under the seashore that hangs floating tunnel bridge cylinder two ends and respectively and is connected with the two ends of hanging floating tunnel bridge cylinder with the second excessive tunnel of bank base.
