Problems solved by technology

[0003] At present, the traditional construction of cast-in-place concrete for pile caps on water generally adopts the method of welding corbels or hoops on the outer wall of steel pipe piles at low tide to build platforms. This construction method has a short operating window and requires steel pipe piles at low tide. When the upper end is exposed to a certain height above the water surface, it is necessary to grab the tidal level for construction, and with the increase of the tidal range in the project water area, the project cost increases sharply, and the construction becomes very difficult. In addition, the construction process is easily attacked by the tide, and the construction quality of the pile cap is difficult to guarantee.

Abstract

The invention discloses an assembly type watertight hanging box formwork for an underwater cast-in-place concrete pile cap, which comprises a hanging box body, one sides of two bottom plates of the hanging box body are rotationally connected with the bottom surfaces of two symmetrically arranged side plates respectively, and the other opposite sides and the four side plates jointly form a box body structure which is arranged on a steel pipe pile in a sealing and sleeving manner; a one-way water stop valve is arranged on any bottom plate; the supporting system is fixed in the steel pipe pile; the power system is arranged on the supporting system and used for driving the first bottom plate and the second bottom plate to rotate around the pair of first side plates so as to seal or open the bottom face of the hanging box body. The invention further discloses a construction method of the fabricated watertight hanging box formwork for the underwater cast-in-place concrete pile cap. According to the method, pile cap dry construction operation conditions can be created in a water level change area, so that the construction window period is prolonged, the construction cost is saved, and meanwhile, the watertight hanging box formwork system has the characteristics of simplicity and convenience in construction, rapidness in mounting and dismounting, reusability and the like.

Description

technical field [0001] The invention relates to the technical field of high-piled wharf construction. More specifically, the present invention relates to an assembled water-tight hanging box formwork and a construction method for an underwater cast-in-place concrete pile cap structure. Background technique [0002] In the process of offshore engineering construction, due to the changeable marine meteorological conditions and seawater movement, the marine engineering construction environment is complex and harsh, the tidal water area changes greatly, and the engineering construction window period is short. In the process of pile cap construction of high-piled wharf, the use of water-tight hanging box formwork with underwater cast-in-place concrete pile cap structure can create dry construction conditions for pile caps in areas where the water level fluctuates, thereby increasing the construction window period and saving construction costs. At the same time, the formwork of t...
