Description

Collapsible portable hydraulic engineering temporary cofferdam Technical Field The utility model relates to the field of hydraulic engineering, in particular to a foldable and portable temporary cofferdam for hydraulic engineering. Background In the hydraulic engineering construction process, the temporary cofferdam is used as a temporary water retaining building and plays an irreplaceable key role. In various water conservancy projects such as river course renovation, dam construction, the construction area often is in the rivers environment, and the temporary cofferdam can effectively cut off rivers, keeps apart construction area and external water, forms dry ground construction environment. The dry environment is convenient for constructors to carry out operations such as earth excavation, foundation pouring, equipment installation and the like, normal operation of construction equipment can be guaranteed, and construction efficiency and quality are greatly improved. At present, when the traditional cofferdam is faced with an irregular construction area, the shape cannot be flexibly adjusted to fit the boundary, so that the water retaining effect is poor, water seepage hidden danger exists, and the construction progress and quality of hydraulic engineering are affected. Therefore, it is necessary to provide a new foldable and portable temporary cofferdam for hydraulic engineering, which solves the above technical problems. Disclosure of utility model In order to overcome the defects existing in the prior art, a foldable and portable temporary cofferdam for hydraulic engineering is provided at present to solve the problems. The foldable and portable temporary cofferdam for the hydraulic engineering comprises two mounting brackets, wherein the two mounting brackets are oppositely arranged, a plurality of enclosing blocks are arranged between the two mounting brackets, one sides, which are located at two edges and relatively far away from each other, of the enclosing blocks are respectively connected with the mounting brackets, rotating parts are arranged between every two adjacent enclosing blocks, the angle between the two enclosing blocks can be adjusted through the rotating parts, and locking parts are arranged above each rotating part, so that the enclosing blocks with the angles adjusted can be fixed through the locking parts. Preferably, the rotating member comprises two adjusting frames arranged between two surrounding baffles, the two adjusting frames are oppositely arranged, one side, far away from the adjusting frames, of each adjusting frame is rotatably connected with an adjusting shaft, and one side, far away from the adjusting shafts, of each adjusting shaft is connected with the surrounding baffles respectively. Preferably, a rotating shaft is arranged between the two adjusting frames, the top and the bottom of the two rotating shafts are both connected with a rotating table, the top and the bottom of one side, which is relatively close to one side, of the two adjusting frames are both connected with guide blocks, and the outer sides of the two rotating tables are both provided with guide grooves corresponding to the guide blocks.
