7. The construction method of the fixed suspension type underwater sightseeing tunnel and the water sightseeing platform according to claim 1, characterized by comprising the following steps:
the method comprises the following steps: at bridge pier and platform positions, transporting a preset processed steel cofferdam to a preset pile position by floating, descending and sinking section by section, fixing, erecting an operation platform on the steel cofferdam, arranging a steel pipe pile casing below the steel cofferdam, erecting a drilling machine for drilling, or selecting steel pipes to be driven into piles according to geological conditions for driving;
step two: according to design drawings and erected platforms, driving a steel pipe structure into a seabed to be embedded into a rock stratum to a certain depth or pouring a marine reinforced concrete pile foundation in the seabed;
step three: after the construction of the pile foundation is finished, embedding a prefabricated bearing platform or pouring an underwater marine concrete bearing platform under water, connecting the bearing platform and a pile foundation into a whole to bear force, installing a lower-layer sightseeing tunnel section I, II at the bottom layer after the strength of the bearing platform and an upright post reaches the design requirement, anchoring, and strictly sealing and preventing leakage of the splicing of the underwater tunnel pipe sections according to the design requirement, wherein the strength of the wall of the tunnel pipe section and other materials can bear the pressure in the depth of the preset water;
step four: erecting a reinforcement cage of the upright column and a steel pipe wall of the outer sleeve through a connecting rib or a connecting piece reserved on the bearing platform, and pouring underwater high-performance marine concrete to a preset elevation above the water surface;
step five: sinking the designed and prefabricated lower-layer sightseeing tunnel section I and the impervious waterproof elevator shaft, the pedestrian stairway and the ventilation duct shaft to preset elevations and positions according to requirements, and carrying out anchoring and anti-corrosion treatment through anchoring holes or bolts reserved on a bearing platform;
step six: sinking the designed and prefabricated lower-layer sightseeing tunnel section II to a preset elevation and position, connecting and anchoring the lower-layer sightseeing tunnel section II through an anchoring hole or a bolt reserved on a bearing platform and a connecting section of the sightseeing tunnel section I and the lower-layer sightseeing tunnel section II, and performing anti-seepage and anti-corrosion treatment;
step seven: pouring marine concrete of upper-layer platform curved beams, upper-layer platform radial longitudinal beams, upper-layer platform upright post cover beams and upper-layer platform cross beams above the water surface, and forming the marine concrete into a whole to form a stressed framework of the upper-layer sightseeing platform;
step eight: and an intelligent monitoring control device is also installed and comprises a plurality of sensors with different functions and a control system for structural safety analysis, evaluation, early warning and emergency.
