Problems solved by technology

[0005] (1) The positioning ship is connected to the cofferdam through the cable, which occupies a large area of ​​the river, has high construction cost, long construction time, and low positioning accuracy; The extension rod is connected to the cofferdam through a positioning rod. The area of ​​the cofferdam is large, and only one positioning rod is used for positioning, so the positioning accuracy is low
[0006] (2) The inner wall of the cofferdam is provided with a fixed system, which is connected to the pile foundation casing through a rolling guide system, and the fixed system is fixedly connected to the guide system. The cofferdam and the pile foundation casing cannot move relative to each other in the horizontal direction, and the positioning device is easily damaged , increasing the construction cost

Abstract

The invention discloses a cofferdam positioning system and relates to the field of a bridge foundation construction device. The cofferdam positioning system comprises a pile foundation casing and a cofferdam positioning device, wherein the cofferdam positioning device comprises a first transverse device and a first longitudinal device. The first transverse device and the first longitudinal device comprise two pull plates and mooring ropes provided with power devices. A steering buckle is arranged at the connecting position between the pile foundation casing and the first transverse device, a steering buckle is arranged at the connecting position between the pile foundation casing and the first longitudinal device, one end of each mooring rope is connected with one pull plate, and the other end of each mooring rope penetrates the steering buckle to be connected with the other pull plate. The cofferdam positioning system can control the motion direction of steel wire ropes and further can accurately position a cofferdam. The pile foundation casing and the cofferdam positioning unit are made of steel and high in strength, the positioning device is not easily damaged, the construction cost is effectively reduced, the operation is convenient, and the construction difficulty is effectively reduced.

Description

technical field [0001] The invention relates to the field of bridge foundation construction equipment, in particular to a cofferdam positioning system. Background technique [0002] In bridge foundation construction, cofferdams are usually set up around bridge piers and abutment foundations for waterproofing, surrounding water and supporting the pit walls of foundation pits. In order to improve the quality of cofferdam construction, it is necessary to lower the cofferdams to the design height. In the process, the cofferdam is accurately positioned to ensure the smooth progress of the bridge foundation construction. [0003] The positioning methods adopted in the existing bridge construction include the following: (1) the positioning ship is positioned by connecting the cable with the cofferdam; (2) a positioning extension rod is set on the outer wall of the pile foundation casing, and the positioning extension rod Connect with the cofferdam through a positioning rod for pos...
