In order to achieve the above purpose, the present invention provides the following technical solutions:
the deepwater steel cofferdam structure comprises a plurality of rectangular plate-shaped cofferdam straight insertion plates and a plurality of arc-shaped cofferdam bent insertion plates, rectangular plate-shaped mounting plates are vertically arranged on two sides of each of the rectangular plate-shaped cofferdam straight insertion plates and the rectangular plate-shaped cofferdam bent insertion plates, a layer of sealing gasket is arranged on the outer wall of each mounting plate, the sealing gaskets at the end parts of the adjacent cofferdam straight insertion plates or the adjacent cofferdam bent insertion plates are mutually attached, the two corresponding mounting plates are fixedly connected through a plurality of pairs of bolts and nuts which are in threaded fit with each other, and a plurality of straight rod-shaped supporting rods are.
As a further optimization of the technical scheme, the straight cofferdam inserting plate and the bent cofferdam inserting plate are both made of stainless steel.
As a further optimization of the technical scheme, the mounting plate is made of stainless steel, and the straight cofferdam inserting plate and the bent cofferdam inserting plate are connected with the mounting plate through welding.
As a further optimization of the technical scheme, the sealing gaskets are all made of rubber materials and are connected with the mounting plate through waterproof adhesives.
As a further optimization of the technical scheme, the supporting rods are all made of stainless steel and are connected with the cofferdam straight inserting plate or the cofferdam bent inserting plate through screws.
The beneficial effect of adopting above technical scheme is: when the deepwater steel cofferdam structure is installed, the straight cofferdam inserting plate and the bent cofferdam inserting plate can be inserted into the deepwater with proper underground depth, the straight cofferdam inserting plate and the bent cofferdam inserting plate are in a shape of a cylinder surrounded by the cylinder, the adjacent mounting plates are mutually attached, then the adjacent mounting plates are fixedly connected by bolts and nuts, the compression sealing gasket plays a role in sealing, the supporting rods are fixedly installed in the cylinder, the functions of fixedly supporting the straight cofferdam inserting plate and the bent cofferdam inserting plate are played, and the cofferdam engineering can be completed after water pumping. The cofferdam straight inserting plate and the cofferdam bent inserting plate in the deepwater steel cofferdam structure are novel and reasonable in structural design, convenient to connect with each other and good in sealing performance, and the cofferdam construction efficiency is improved.
