Detailed Description
To further disclose the contents, features and functions of the present invention, the following examples are given in detail in conjunction with the accompanying drawings.
A cofferdam with reinforced support columns is provided, wherein the reinforced support columns are connected with the cofferdam and are arranged perpendicular to the cofferdam; the reinforced support column comprises a vertical support structure and a transverse support structure; the vertical supporting structure is arranged along the transverse supporting structure; the vertical supporting structure is fixedly connected with the transverse supporting structure. The reinforced support columns mainly play a role in relieving the impact force on the side surfaces of the cofferdam structure, and the reinforced support columns have the best effect of relieving the impact force when the reinforced support columns are perpendicular to each other.
The cofferdam is preferably a steel sheet pile cofferdam. And enclosing purlins are arranged on the inner sides of the steel sheet pile cofferdams, and steel pipe inclined struts are arranged at inner corners.
The number of the vertical supporting structures is two or more. The number of vertical support structures is preferably three. Three vertical supporting structures are fixed at the two ends and the middle part of the transverse supporting structure respectively, so that the stability of the whole structure of the reinforced supporting column is better.
The vertical support structure is preferably a hollow round tube. Compared with a solid cylinder, the hollow circular tube has light weight and low manufacturing cost. And fixing tables are arranged on the left side and the right side of the upper part of the vertical supporting structure. The lateral support structure is located on the fixed table. The fixing table is arranged to facilitate connection of the transverse supporting structure and the vertical supporting structure.
The number of lateral support structures is preferably two. The transverse support structure is preferably a double-layer i-steel. The double-layer I-shaped steel has better structural stability.
Example 1: referring to fig. 1-4, the length and width of the cofferdam 6 are both around 40m, since the length of the drainage pipe 10 is about 16.4m and the river bottom protection building 11 is 29m by 26.3 m. A cofferdam 1 with reinforced supporting columns is provided, the reinforced supporting columns 1 are arranged perpendicular to a cofferdam 6, the reinforced supporting columns 1 comprise vertical supporting structures 2 and transverse supporting structures 3, and the vertical supporting structures 2 are arranged along the transverse supporting structures 3; the vertical supporting structure 2 is fixedly connected with the transverse supporting structure 3; the reinforced support column 1 is connected with the cofferdam 6; the distance between each reinforcing support column 1 is 5-6 m. The cofferdam 6 is a steel sheet pile cofferdam with the height of 6 m. And a surrounding purlin 8 is arranged on the inner side of the steel sheet pile cofferdam, and a steel pipe inclined strut 9 is arranged at an inner angle.
