Abstract

The invention relates to the technical field of bridge construction, in particular to a double-wall cofferdam and a pier body construction method utilizing the double-wall cofferdam. The double-wall cofferdam comprises at least one section of double-wall cofferdam unit. The double-wall cofferdam unit comprises a wall body, a cutting edge, an inner supporting rod and a guiding mechanism. The cutting edge is arranged at the bottom end of the wall body. The inner supporting rod is horizontally located in an inner surface plate of the wall body, and is connected with the inner panel of the wall body. The guide mechanism comprises a connecting rod and a guide plate, and the guide plate is connected with the inner panel of the wall body through the connecting rod, the bending degree of the guideplate is matched with the curvature of the outer wall surface of a protection tube of a drilling pile, and a distance is formed between the guide plate and the outer wall surface of the protection tube. The inner supporting rod can enhance the stability of the double-wall cofferdam. The guide plate can guide and locate the lowering process of the double-wall cofferdam. Therefore, the double-wallcofferdam has the advantages that the structure strength is improved, stability is high, water stopping effect is good, structural design is reasonable, the structure is not required to be adjusted for multiple times in the construction process, and the smooth proceeding of engineering is guaranteed.

Description

technical field [0001] The present application relates to the technical field of bridge construction, in particular to a double-walled cofferdam and a pier body construction method using the double-walled cofferdam. Background technique [0002] At present, China is in a period of rapid development of railway bridge construction, and a large number of large-span railway bridges across rivers, rivers and seas have been built. The deepwater foundation cap is a controlling project of this kind of large-scale project. Due to the influence of natural conditions and technical reasons, the construction is often difficult to control, which seriously affects its construction progress. As the key technology for the success of this type of bridge construction: steel cofferdam construction technology is constantly innovating. At present, steel cofferdams and steel sheet piles have become two main water-retaining structures and construction methods in the construction of deep-water foun...
