Problems solved by technology
However, the top of the caisson wall and the lower part of the parapet wall are generally located within the range of the water level fluctuation area, and the water-facing surface of the parapet wall generally protrudes more outward than the water-facing wall of the caisson. After the component is formed, the lines are not straight, the component is deformed, etc.
The light will affect the apparent quality, and the heavy will affect the durability and safety of the dock

Embodiment Construction
[0032] The following is attached Figure 1-2 The application is described in further detail.
[0033] The embodiment of the present application discloses a support system for a bottom formwork of a concrete parapet wall of a gravity-type circular caisson. refer to figure 1 , including several supporting girders 2 arranged on the circular caisson 1, one end of the supporting girders 2 is buried in the circular caisson 1, and the other end of the supporting girders 2 passes through the side wall of the circular caisson 1 to be cantilevered. A diagonal bracing beam 3 is fixedly connected between the lower surface of the supporting girder 2 and the side wall of the round caisson 1 to enhance the bending resistance of the supporting girder 2 .
[0034] refer to figure 1 A number of supporting main beams 2 are divided into two sets of oppositely arranged longitudinal beams 22 and two sets of oppositely arranged crossbeams 21, and two sets of crossbeams 21 and two sets of longitud...

The invention discloses a gravity type circular caisson concrete breast wall bottom formwork supporting system. The gravity type circular caisson concrete breast wall bottom formwork supporting system comprises a plurality of supporting main beams arranged on a circular caisson, one of the ends of the supporting main beams is embedded in the circular caisson, and the other one of the ends of the supporting main beams extends to penetrates out of the side wall of the circular caisson; four sets of supporting auxiliary beams which are sequentially connected end to end and used for laying a bottom formwork are arranged on the multiple supporting main beams, the four sets of supporting auxiliary beams are arranged on the periphery of the circular caisson in a surrounding mode and are arranged in a rectangular shape, four sets of hoisting mechanisms are arranged at the top of the circular caisson, and the hoisting point of each set of hoisting mechanism is located at the joint of every two adjacent sets of supporting auxiliary beams. The gravity type circular caisson concrete breast wall bottom formwork supporting system has the effect of enhancing the bearing capacity of the bottom formwork.
Description
technical field [0001] The present application relates to the technical field of civil engineering, in particular to a support system for the bottom formwork of a gravity-type circular caisson concrete parapet wall. Background technique [0002] The caisson gravity wharf is a very important structure in the wharf structure. Its structure is firm and durable; it has good frost resistance and ice resistance; it can bear large ground loads and ship loads, and has the ability to withstand large concentrated loads and the wharf ground. The characteristics of strong adaptability to overloading and loading and unloading process changes have been widely used in wharf engineering. [0003] According to its appearance characteristics, the caisson usually adopts two types of square and round. Among them, due to the curved shell structure, the circular caisson has good stress conditions, small bending moment, and smaller wave reflection at the front than the square caisson, which is be...
