The invention provides a detachable and reusable steel pipe cofferdam and a construction method thereof. The detachable and reusable steel pipe cofferdam is used for cofferdam construction of a river channel with a river-crossing bridge, and comprises vertical rods, cross rods, pull rods, inclined supports, breast boards and waterproof cloth; wherein the multiple vertical rods are inserted into the bottom of the river channel along one side of the river-crossing bridge; the cross rods are located above the water surface of the river channel and detachably connected with the multiple vertical rods in the direction of the river-crossing bridge; one ends of the pull rods are detachably connected onto the vertical rods or the cross rods, and the other ends of the pull rods are detachably connected onto the river-crossing bridge; one ends of the inclined supports are connected onto the vertical rods or the cross rods, the other ends of the inclined supports are inserted into the river channel, and the inclined supports are located on the downstream faces of the vertical rods; the breast boards are located on the upstream faces of the vertical rods and detachably connected onto the multiple vertical rods, and the lower ends of the breast boards are anchored into the bottom of the river channel; and the waterproof cloth is arranged on the surfaces of the breast boards and located on the upstream faces of the breast boards.
Description
technical field [0001] The application relates to the technical field of river course management, in particular to a detachable and reusable steel pipe cofferdam and a construction method thereof. Background technique [0002] In the process of river internal source treatment, it is necessary to build cofferdams for dredging in sections. Traditional construction cofferdams mostly use soil cofferdams or sand bag cofferdams, while existing riverside facilities and structures along the rivers in cities and towns are all In the construction process of the traditional cofferdam, firstly, when the water level in Hanoi is high, the cofferdam requires a large amount of soil; secondly, the filled cofferdam is easily washed away by accumulated water, resulting in rework; thirdly, the cofferdam During the construction process, the existing coastal zone was damaged greatly and construction access roads needed to be built; fourthly, cofferdams were difficult to dismantle and clean and co...
