Problems solved by technology

Most of the parts are connected by welding, and the joint parts must be cut off after each construction and must be scrapped because they cannot match other construction structures, which increases the production cost and wastes a lot of man-hours

Abstract

The invention discloses a modular steel cofferdam inner supporting system. The inner supporting system comprises a waling, a pair of inner supports and a pair of one-way adjusting devices, wherein theinner supports are symmetrically arranged in the square-ring-shaped waling in a supporting mode; each inner support comprises a pair of inclined supports, a straight support and a bidirectional adjusting device; the pair of inclined supports and the straight support form a triangular supporting main body; the bidirectional adjusting device is arranged at the ends, close to each other, of the pairof inclined supports and is used for adjusting the angle between the pair of inclined supports; the pair of one-way adjusting devices is correspondingly arranged at the two ends of the straight support respectively; the bidirectional adjusting device and the one-way adjusting device each comprise a base and an adjusting surface; the adjusting surface is arranged on the base and can be subjected to angle change relative to the base; and the two ends of the pair of inclined supports are connected to the adjusting surfaces on the metal plates on the corresponding sides of the waling. The systemcan be widely applied to the technical field of cofferdam supporting.

Description

technical field [0001] The invention relates to the technical field of cofferdam support. More specifically, the present invention relates to a modular steel cofferdam internal support system. Background technique [0002] Steel cofferdams are generally used in the construction of bridge pile foundations and caps to retain water and soil to provide a safe construction environment. The steel cofferdam structure is mainly composed of the outer support structure and the inner support system. The construction form of the cofferdam is mainly divided into the first support method and the second support method: [0003] During the construction of the first-supported cofferdam, the cofferdam structure and internal support system are usually welded in advance, and then lowered to the construction site, and then the external support system is inserted and installed. After the construction in the cofferdam is completed, the internal support system is removed and the corresponding con...
