Abstract

The present invention provides a deep-water construction method of a bridge at water pebble soil and argillaceous sandstone areas and an auxiliary working platform. A foundation adopts two foundations of steel pipe piles and anchor piles. The steel pipe piles are formed through inserting and piling by a pile hammer, and borne in pebble soil and argillaceous sandstone, pilebolck distributive girders of the steel pipe piles adopt profile steel, a main longitudinal girder is a Bailey girder or a girder at other types, the profile steel is arranged on the main longitudinal girder, a faceplate adopts a riffled steel plate, a protective railing is arranged on the edge, and thus a combined type working platform on which mechanical equipment of large gantry cranes, crawler cranes and the like can walk is formed. According to the invention, the steel pipe piles and the anchor piles are mutually matched, the steel pipe piles are mainly used for bearing the load on the platform, the anchor piles are mainly used for bearing water flowing force, a trestle stand and a drilled platform are integrated, the trestle stand and the platform can be propelled synchronously towards the river from the shore side during construction, so that the combined type working platform is quickly formed, materials, equipment and the personnel pass the combined type working platform, and thus multiple processes of construction of pile foundations and pile caps of deep-water foundations of large bridges at deep-water pebble soil and argillaceous sandstone areas of rivers, lakes and seas can be performed.

Description

technical field [0001] The invention relates to the technical field of bridge construction, in particular to a deep-water construction method and an auxiliary working platform for bridges in pebble soil and argillaceous sandstone areas. Background technique [0002] The construction of large-scale bridge foundations in pebble soil and argillaceous sandstone areas is difficult, and the construction method of independent anchor piles takes a long time and requires a large investment. The foundation emergency engineering and node rush projects cannot meet the requirements of bridge foundation construction. The construction speed of the independent driven steel pipe piles is fast, but it cannot meet the stress requirements of the trestle platform for crossing the flood in the pebble soil and muddy sandstone area. The problem that the lateral stiffness of the trestle bridge is too weak enables the structure to more effectively resist the impact of water flow and ensure the safety...
