Novel combined steel open caisson

Abstract

The invention provides a novel combined steel open caisson which comprises a top joint, a middle joint and a bottom joint which are sequentially spliced from top to bottom. The top joint and the middle joint are the same. The middle joint comprises a rectangular frame body structure formed by combining two first module plates and two second module plates, wherein the two first module plates are perpendicular to the two second module plates, and every two adjacent first module plate and second module plate are connected through a bolt. The bottom joint comprises a rectangular frame body structure formed by combining two third module plates and two fourth module plates, wherein every two adjacent third module plate and fourth module plate are connected through a bolt. Compared with the priorart, the novel combined steel open caisson has the beneficial effects that splicing is simple, operation is convenient, recycling can be achieved, the construction cost is saved, the construction time is saved, the self rigidity is high, the dead load is small, the construction period can be greatly shortened, the transporting and lifting cost is saved, the traffic impact time during constructionis short, seepage can be prevented, and construction is safer.

Description

technical field [0001] The invention relates to the technical field of steel caissons, in particular to a novel combined steel caisson. Background technique [0002] There are many shortcomings and deficiencies in the existing concrete caissons, such as the construction of concrete caissons requires a lot of formwork, scaffolding, steel, concrete and a lot of labor, especially the construction period is long, it cannot be recycled, wastes resources, and affects traffic It takes a long time, it is easy to break and cause leakage, and a large number of concrete transport vehicles and pump trucks are needed, which will have a greater impact on traffic when pouring concrete. Contents of the invention [0003] In order to solve the above problems, the present invention discloses a novel combined steel caisson, which is not only simple to assemble and easy to operate, but also recyclable and reusable, saving construction cost. [0004] In order to achieve the above object, the ...
