[0002] The vortex well technology also plays a vital role in the metallurgical industry. In the metallurgical production process, the vortex well is used for wastewater treatment and recycling, which is of great significance for improving production efficiency, reducing production costs and environmental protection. The vortex well technology has been widely used in the metallurgical industry with its unique advantages and efficient processing capabilities.

[0003] The swirl well caisson is a special construction method used in the construction of swirl wells for steelmaking and continuous casting. Through a specific support method and construction sequence, the safety and smooth progress of the construction are ensured. However, during the construction of the swirl well caisson, the construction of the well wall behind the caisson requires the erection of a scaffolding frame. During the erection process, the scaffolding must ensure that the frame system is safe and stable. The traditional method is to start the erection from the bottom of the swirl well, which is time-consuming and labor-intensive. During the erection process, the bottom area of ​​the swirl well is taken for construction. When the bottom construction is required, all the frames must be dismantled, and the frames must be re-erected after the bottom construction is completed. The process is cumbersome, the construction is completed, and it wastes manpower and material resources. Summary of the invention

Calculate the spacing of the well wall scaffolding according to the drawing dimensions, and divide and arrange the embedded parts of the scaffolding support of the vortex well wall; S2. Fabricate the embedded parts of the bracket according to the number of embedded parts, and fabricate the steel bracket of the scaffolding in advance; S3, construction, during construction, the second bracket embedded parts with swirl well are pre-buried on the top of the first section of the well wall; S4. After the first zone of well wall is poured with concrete, the well is caissoned. After the well is caissoned, the steel supports inside and outside the well are installed; S5. Install the steel bracket on the bracket embedded parts according to the frame spacing, and use channel steel to connect and reinforce the steel bracket; S6, erecting scaffolding according to the frame spacing in step S1; S7, tying the second zone shaft wall with steel bars, and burying the third zone bracket embedded parts on the top of the second zone shaft wall; S8. Repeat steps S4 to S7 to construct the subsequent shaft wall in sections until all the scaffoldings of the shaft wall are completed.

DETAILED DESCRIPTION

[0010] In order to fully understand the purpose, features and effects of the present invention, the present invention is described in detail through the following specific implementation methods, but the present invention is not limited thereto.

[0011] A method for constructing a scaffolding template for a vortex well wall support is carried out according to the following steps: S1. Analyze and calculate according to the vortex well structure construction drawing, divide the vortex well wall into sections, calculate the step, span and horizontal distance of the double-row scaffolding inside and outside the vortex well, design the scaffolding erection specifications and form, and calculate the bottom channel steel erection distance to bear the upper load; and divide the vortex well wall scaffolding support embedded parts into sections and arrange their positions.

[0012] S2. The embedded parts of the bracket are made according to the number of embedded parts. The embedded parts of the bracket are rectangular structures with dimensions of 240*800*20mm. Anchor claws are arranged on the embedded parts of the bracket, and the length of the anchor claws is 200mm. The steel bracket is in the form of a tripod composed of two 200*100 steel sections. When welding the steel bracket, full welding is adopted.

[0013] S3. Carry out the construction of the first vortex well. During the construction process, first tie the steel bars of the first vortex well wall, and then embed the pre-made bracket embedded parts of the second vortex well wall on the top of the first vortex well wall, and strictly ensure that the position of the bracket embedded parts conforms to the advance layout design.

[0014] S4. Pour concrete for the first vortex well wall. After the pouring is completed, carry out the caisson construction. After the caisson is completed, install the steel bracket on the bracket embedded parts.

[0015] S5. After the steel bracket is installed, install the channel steel support between the steel brackets. The channel steel support uses [100 specifications. During the connection process, because the vortex well is circular, the joints between the steel bracket and the channel steel need to be cut and welded to ensure that the elevation of the steel bracket is consistent.

[0016] S6. After the channel steel is laid, the internal and external scaffolding is erected on the channel steel. The scaffolding step, spacing, horizontal distance, etc. designed in advance are strictly followed in the process of erecting the frame. The position of the scaffolding poles must be ensured to be erected in the middle of the channel steel.

[0017] S7. Tie the steel bars to the second zone of the shaft wall, bury the inner and outer bracket embedded parts of the third zone on the top of the second zone of the shaft wall, and carry out mold closing and concrete pouring.

[0018] S8. Repeat steps S4 to S7 to perform segmented construction on the subsequent cyclone shaft wall until all the scaffolding on the shaft wall is completed.

[0019] The present invention embeds support embedded parts during the construction process of the vortex well wall, installs steel supports for inner and outer frames of the well wall, and erects inner and outer frame structures on the steel supports, thereby ensuring the safety and stability of the construction frame structure and saving the need to re-erect the frame from the bottom of the vortex well each time, thereby saving construction time and erection costs.

[0020] Finally, it should be noted that the above are only preferred embodiments of the present invention. Of course, those skilled in the art can make changes and modifications to the present invention. If these modifications and variations fall within the scope of the claims of the present invention and their equivalent technologies, they should be considered to be within the scope of protection of the present invention.
