Adjustable base assembly structure of steel cofferdam

Abstract

The invention discloses an adjustable base assembly structure of a steel cofferdam. The adjustable base assembly structure comprises a lower base, an upper base and cofferdam side plates. A horizontallower base body and an inclined lower base body of the lower base are hinged together through a rotary shaft. A horizontal upper base body and the horizontal lower base body are fixedly connected together through a fixed connecting plate. An inclined upper base body is sleeved with a bottom sleeving groove of the inclined lower base body through a movable inserting plate. After the cofferdam sideplates penetrate the upper base from an upper slot, the lower portions of the cofferdam side plates are sleeved with the corresponding bottom sleeving groove, and the side faces of the adjacent cofferdam side plates are in embedded connection in a convex-concave fit manner. Meanwhile, a lifting adjusting mechanism is arranged between the inclined upper base body and the inclined lower base body.According to the adjustable base assembly structure, by means of the cooperating relation between the lower base and the upper base, the cofferdam side plates can be sealed and fixedly connected together, and a cofferdam body is formed. The lower base provides bottom supporting, the upper base provides middle supporting, and the overall structural strength is stable and reliable.

Description

Technical field: [0001] The invention belongs to the technical field of cofferdams for reconstruction of engineering canals, and in particular relates to an adjustable base assembly structure of steel cofferdams. Background technique: [0002] Most of the steel cofferdams used at home and abroad mainly consider the stability of the structure and analyze the stress of each part, while ignoring the flexibility and effectiveness of the design for various complex terrains. In terms of water channel maintenance technology, for water channels made of stone or cement that are not easy to drill, have limited load bearing, and the underwater buildings where the construction site is relatively hard, traditional mud-bound soil and rock cofferdams, cement jet grouting pile cofferdams , Weir surrounded by woven bag sand and other structures are unstable, the construction and demolition process is complicated, the cost is high, the load is too large, the environmental pollution is serious...

[0002] Most of the steel cofferdams at home and abroad mainly consider the stability of the structure and analyze the stress of each part, while ignoring the flexibility and effectiveness of the design for various complex terrains.

In terms of water channel maintenance technology, for water channels made of stone or cement that are not easy to drill, have limited load bearing, and the underwater buildings where the construction site is relatively hard, traditional mud-bound soil and rock cofferdams, cement jet grouting pile cofferdams , the weir surrounded by woven bag sand and other structures are unstable, the construction and demolition process is complicated, the cost is high, the load is too large, the environmental pollution is serious, it is not easy to adopt, and there is still a gap in the cofferdam construction technology for special environments

There are still gaps in similar inventions for slope adjustment of different channels at home and abroad
