Tunnel body is connected with each other by the spar structures on connecting structure structure and top, and the buoyant equilibrium tunnel provided by spar structures
The remaining gravity of road body and later stage operation load；Pontoon bridge system, the width control of pontoon bridge system are set up on spar structures simultaneously
System is furnished with corresponding attached safety devices in the range of 3~5m, so as to realize across waters traffic vehicle road and non-motor vehicle
Road is separated.
Pontoon bridge telescopic section is set in pontoon bridge system, the elongation of pontoon bridge is realized by the control at pontoon bridge telescopic section Electromechanical Control station
And shortening.
When ship need by when, by pontoon bridge telescopic section Electromechanical Control station input it is " current " order, pontoon bridge telescopic section
Interrupted with pontoon bridge connecting interface, so that floating drum movable bearing support is raised to the height specified, and pass through pontoon bridge telescopic section sliding rail
Slide to side；After ship is sailed out of, in pontoon bridge telescopic section Electromechanical Control station input " end " order, pontoon bridge telescopic section is walked as former
Delitescence is back to original position.
Pontoon bridge system can be gone sightseeing for non power driven vehicle and pedestrian it is current, pontoon bridge telescopic section can meet navigation channel waterborne lead to
OK, and submerged tunnel body is available for motor vehicles to travel.
The closed cavity pipe prefabrication that described tunnel body is poured into a mould by high-strength concrete is spliced.
Closed cavity casing that described spar structures are poured into a mould by high-strength concrete is prefabricated to be formed.
Described connecting structure structure uses prestress anchorage cable stretch-draw anchor technology, makes tunnel body and spar structures close
Link together.
Described pontoon bridge system is laid using high-strength light steel plate, and passes through floating drum hold-down support and floating drum movable bearing support
Fixed constraint is on spar structures.
Described attached safety devices include pontoon bridge railing, pontoon bridge drainage conduit body, pontoon bridge illumination, lifesaving appliance.
Beneficial effects of the present invention are as follows：
(1) realize that across waters transport structure car lane is separated with bicycle lane, adapt to the situation of big flow traffic；
(2) total, without setting anchoring underwater support system, can adapt on the premise of not influenceing the water surface to open the navigation or air flight
The poor situation of waters geological conditions, disclosure satisfy that the requirement of military project, national defence to headroom under water；
(3) to the following exploitation of traffic space under water and sightseeing tour, have to social economy and Ecological Civilization Construction important
Meaning.
