For further explanation of the structure of the present invention, the following detailed description is made with reference to the accompanying drawings:

example one

Referring to fig. 1-4, a floating movable water-retaining cofferdam includes a unit square box 1, an air port, a sealing plate 2, and a water port.

The unit square box body is of a regular hexahedron box body structure, and a box chamber is arranged inside the unit square box body. In this embodiment, the unit square box is a container body, and corner portions of the container body are provided with corner connectors. The container body is a packaging tool in a product standardized transportation system, and the structure of the container body is conventional and technical. The container body is used as a unit square box body in the technical scheme, materials are convenient to obtain, and the cost can be controlled. The corner brace member is a cast member provided at an angle of the container body for connection between the container bodies, and its structure is known in the art.

The end parts of the plurality of unit square box bodies are butted end to form a cofferdam body, and the cofferdam body forms a water retaining structure. The water blocking structure refers to a foundation wall structure with water blocking function. In this embodiment, the water blocking structure is a linear wall structure crossing the river. The cofferdam body is used as a basic structure for retaining water of a river channel, and sand bags, water seepage prevention canvases and the like can be arranged on the cofferdam body. In the embodiment, the shore grooves are dug symmetrically at the left and right sides of the revetment of the river channel, and the distance between the two shore grooves is an integral multiple of the length of the container body. The linear wall-shaped water retaining structure consisting of a plurality of container bodies is transversely and tightly extruded and placed between the two shore grooves.

The air port is arranged on the upper end surface of the unit square box body and is communicated with the box chamber of the unit square box body. The shrouding is installed on the up end of unit square chest body, and the shrouding shutoff gas port. The water port is arranged at the lower part of the unit and is communicated with the box chamber of the unit square box body. Under the state that the unit square box body floats and moves on the water surface, the sealing plate blocks the air port, and under the action of air pressure, the unit square box body can float and move on the water surface under the condition that air exists in a box chamber of the unit square box body. And after the unit square box body moves to the calibration position, the closing plate is opened, the air pressure is relieved, water is filled into the box chamber of the unit square box body from the water port of the unit square box body, and the unit square box body filled with water finally sinks underwater to form a water retaining base component. In order to ensure the structural stability of the unit square box body, a grid support frame body formed by assembling scaffold frames can be additionally arranged in the unit square box body. In order to further improve the stability of the unit square box body after sinking, a sand bag can be placed in the unit square box body, and the unit square box body can be ensured to float under the condition that air pressure exists in the box chamber.

The hexahedral tank structure can completely prevent the water retaining structure from being broken and burst by contacting and extruding the end face of the unit square tank under the state of ensuring no horizontal movement allowance and under the state of receiving the pressure of the upstream face.

The corner brace component is provided with a twist lock 3, a bridge piece 5 is connected between the twist locks, and the two butted unit square boxes are connected through the bridge piece. Specifically, the bridging piece is a rigid plate, and through holes for penetrating and locking the twist locks are formed in two ends of the bridging piece. Twist locks are conventionally known components that can be mounted on corner brace members of container bodies. The bridging member is used for realizing rigid connection between the two container bodies.

Furthermore, the bridge piece is provided with an ear plate, the ear plate is connected with a diagonal brace 4, and the diagonal brace is positioned on one side of the back water surface of the cofferdam body. Specifically, the side part of the bridging piece is provided with an integral side plate bent downwards, two symmetrical lug plates are welded on the side plate, and bolt holes are formed in the two lug plates. The upper end of the inclined strut is also provided with a bolt hole, the upper end of the inclined strut is connected with the lug plate after the bolt and nut assembly penetrates through the bolt hole, and the inclined strut forms further reliable support on the water retaining structure in the back water surface.

When the water retaining structure is detached, the connection between the unit square box bodies is firstly released, then the sealing plates of the unit square box bodies are opened, and the high-pressure air pump is used for filling air into the box chambers of the unit square box bodies through the air holes, so that the unit square box bodies float upwards.

Example two

Referring to fig. 5, the difference between the embodiment and the first embodiment is the shape of the water retaining structure, and specifically, the water retaining structure is an arched wall structure crossing the river. The water retaining structure in the embodiment is also formed by butting a plurality of unit square box bodies. Specifically, groove-shaped supporting foundations are constructed on the left and right symmetrical sides of the river channel revetment. If necessary, the support structure can be prefabricated on site from concrete. The length of the bridging piece close to the upstream surface is larger than that of the bridging piece close to the downstream surface, so that the water retaining structure forms an integral arched structure, and a sand bag is filled in a gap between two adjacent unit square boxes. Compared with a linear wall structure, the structure has stronger water retaining capacity.

The above description is only exemplary of the present invention and should not be construed as limiting the present invention, and any modifications, equivalents and improvements made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
