Description

TECHNICAL FIELD

[0001] The utility model relates to gravity type caisson wharf caisson dock-in technical field especially relates to a steel cushion beam for caisson water bag - hydraulic platform truck conversion dock-in. BACKGROUND

[0002] Gravity type caisson wharf is a kind of wharf structure form that is widely distributed and more used in our country.In recent years, with the reduction of gravity type wharf engineering, the continuous hot development of offshore wind power project, part of large floating dock in domestic has been reformed for offshore wind power installation construction, and gravity type caisson wharf construction process often faces the situation that floating dock and prefabrication yard design shipping process do not match, and large-scale reconstruction construction is needed for prefabrication yard pedestal and shipping mouth to meet the dock-in demand, and the reconstruction construction cost is high, and the construction period is delayed.

[0003] In the construction process of gravity type caisson wharf, caisson dock-in scheme mainly has three construction methods of air bag rolling dock-in, water bag platform truck dock-in and hydraulic platform truck dock-in, and the above three construction methods have specific requirements for prefabrication yard pedestal, shipping mouth layout and floating dock.Through the statistical analysis of the conventional caisson dock-in process of previous similar projects, it is found that the main time consumption and cost increase of conventional caisson dock-in process when facing the situation that floating dock and prefabrication yard design shipping process do not match are as follows:

[0004] 1, air bag rolling dock-in process: since air bag rolling dock-in has higher requirements for the flatness of prefabrication yard pedestal ground, and the safety factor is lower than that of platform truck dock-in process, therefore, at present, most of the prefabrication yards are set according to the platform truck dock-in process, and the platform truck ditch is arranged in the prefabrication yard pedestal, which penetrates the whole pedestal.The floating dock and prefabrication yard design shipping process do not match, and the caisson has been prefabricated, so the prefabrication yard ground cannot be transformed into air bag rolling to form a horizontal plane, and this process is not suitable when facing the situation that floating dock and prefabrication yard design shipping process do not match.

[0005] 2, water bag platform truck dock-in process: since there is a height difference between floating dock deck and pedestal ditch, water bag platform truck cannot pass through the intersection of pedestal and floating dock deck.The water bag platform truck can be docked by lowering the elevation of bottom beam and lowering the elevation of floating dock deck to make them flush with the pedestal ditch.But this scheme needs to transform the prefabrication yard bottom beam to lower the elevation of bottom beam, and the construction time needs about 60 days, and the construction cost needs about 2.4 million yuan, so the construction period is long and the cost is high.

[0006] 3. The hydraulic trolley dock process: the floating dock deck and the precast yard pedestal ditch exist high difference, need to fill the high difference, make the hydraulic trolley can be loaded on the caisson through the pedestal and the deck surface intersection drive to the upper part of the floating dock. Because the caisson arrangement on the pedestal is far away from the front edge of the pedestal, the last end caisson is more than 250 meters away from the front edge of the pedestal, if the hydraulic trolley is used to dock, 4 ditches need to be leveled by steel cushion beam, it is estimated that 1000 tons of steel cushion beam need to be processed, the cost is about 8 million yuan, the processing period needs 80 days, the cost is high and the period is long.

[0007] The caisson docking is the premise of the caisson delivery and installation, and the conventional caisson docking process needs to make a large number of modifications to the precast yard when the floating dock and the precast yard design delivery process do not match, which has a long construction period, high cost, affects the main task of the project, and has become a bottleneck restricting the overall progress.
