Abstract

The invention discloses a rapid construction method for an underwater isolated pier support platform. Inserting and driving of inclined steel pipe piles in water and manufacturing of a platform support on land are conducted at the same time. The platform support is mainly composed of cross beams and longitudinal beams. The platform support is hoisted to the inclined steel pipe piles through hoisting equipment, and welded and reinforced; and concrete is poured on the platform support, and anchorage pier manufacturing is completed. The method is simple in construction, safe and rapid, and smoothconstruction is guaranteed; and the labor investment and working hours can be reduced, the construction cost investment is effectively reduced, and the construction period is shortened.

Description

technical field [0001] The invention belongs to the field of bridge construction, and in particular relates to a rapid construction method for a supporting platform of an isolated pier in water. Background technique [0002] During the positioning construction of the double-wall steel hanging box cofferdam, it is necessary to set up independent anchor piers in different positions in the water, that is, to set up four temporary piers with inclined steel pipe piles as the main load-bearing structure at the four opposite corners of the cofferdam , the pier and abutment are arranged at a certain distance from the cofferdam, and try to avoid the scour range of the cofferdam. Each pier is connected to a corner point of the cofferdam with a cable so as to precisely control the position of the cofferdam. The inclined steel pipe piles are connected into a whole by pouring concrete on the abutment to form an operation platform. Corresponding pulley groups, winches and other facilitie...
