Concrete modular rapid construction cofferdam

Abstract

The utility model proposes a kind of concrete modularization rapid construction cofferdam, including prefabricated component, the horizontal position of prefabricated component is fixedly installed with reinforcing bar, the vertical position of prefabricated component is fixedly installed with steel pipe, the inside of two rows prefabricated component is surrounded with concrete pouring area, wherein the inside pouring of concrete pouring area is provided with underwater concrete block, the top pouring of underwater concrete block is provided with overwater concrete block, it is related to concrete cofferdam technical field.The utility model is by using to pull reinforcing bar and underwater steel pipe pile, and prefabricated concrete component is spliced into underwater unit frame suitable for any specific terrain and underwater unit frame of hydrodynamic field, and underwater concrete is formed cofferdam overall structure in cell, formwork is exempted from demolition, and it is poured using underwater sequence, and it greatly avoids the problem, such as long duration, great construction difficulty of using conventional formwork underwater operation, while reducing single pouring amount, improve the construction efficiency of underwater concrete.
