Description

Technical Field

[0001] The invention relates to the technical field of manufacturing arc-shaped templates for vortex wells, in particular to a method for manufacturing an arc-shaped template for a vortex wellbore wall. Background Art

[0002] The construction of vortex wells is a common and important link in water conservancy and municipal engineering. The shaft wall of a vortex well is usually in the shape of an arc, but the existing formwork method mainly uses flat plates and high-strength bolts for fixing. This method is insufficient in terms of the speed of manual formwork, and because the flat plates cannot completely fit the arc structure of the shaft wall of the vortex well, the control of construction accuracy is not optimistic; gaps and misalignments are easily generated between the plates during the flat plate formwork process, resulting in large deviations in the shape accuracy of the shaft wall after concrete pouring, which may affect the overall use effect of the vortex well. In order to overcome the above problems, a method for making an arc-shaped formwork for the shaft wall of a vortex well is proposed to improve construction quality and efficiency. Summary of the invention

[0003] The present invention aims to solve the above-mentioned problem, thereby providing a method for manufacturing an arc-shaped template for a vortex shaft wall.

[0004] The present invention solves the above-mentioned problem by adopting the following technical solution: A method for manufacturing an arc-shaped template for a cyclone shaft wall, comprising a wooden board, is performed according to the following steps: S1: Preliminary preparation. Before construction, input the diameter of the inner tube of the vortex well into the special program, and calculate the optimal wooden board size, quantity and movement time of the electronic hydraulic device through the program; cut the required wooden boards and pads, and prepare the electronic hydraulic device and jacking fixture that match the program calculation model; after the wooden board is cut, mark the center of the wooden board. This step is the basis for ensuring the accuracy of the subsequent steps; S2: Fix the pads. Fix the pads on the upper end of the electronic hydraulic device to increase the force-bearing area of ​​the wooden board during the upward lifting of the electronic hydraulic device, so as to ensure that the wooden board is evenly stressed and avoid damage to the wooden board due to excessive force at a single point. S3: Install the electronic hydraulic device in the middle of the lifting bracket. The electronic hydraulic device can accurately control the curvature of the board and make precise adjustments through the movement time calculated by the program. S4: Fix the wooden board, place the wooden board above the electronic hydraulic device, and position the two ends through the jacking fixing frame; S5: Shape making and maintaining. After installation, the making starts. By starting the electronic hydraulic device, the board gradually forms the required curvature. When the curvature reaches the design requirement, it is maintained for a period of time to ensure the shape of the board is stable. S6: Dismantling and completion. After the shape of the wooden board is fixed, the electronic hydraulic device is depressurized and dismantled. At this point, the production is completed.

[0005] Further, inspection and correction are carried out to check the size and curvature of the finished curved wooden board. If there is any deviation, appropriate correction is made.

[0006] Furthermore, the jacking and fixing frame includes a base plate, and F-shaped frames are symmetrically arranged on the top surfaces of both ends of the base plate, and the openings of the F-shaped frames are opposite to each other. The two ends of the wooden board are placed between the two horizontal sections of the F-shaped frame to limit the height of the two ends of the wooden board; a cylindrical pressure roller is arranged below the upper horizontal section of the F-shaped frame to make the displacement of the two ends of the wooden board smoother during the forming process; a sliding seat is slidably connected to the middle of the base plate, and a mounting seat for installing an electronic hydraulic device is arranged above the sliding seat to facilitate the adjustment of the position of the electronic hydraulic device so that the top end of the electronic hydraulic device is against the center of the wooden board, and the height of the top surface of the electronic hydraulic device is lower than the height of the top surface of the lower horizontal section of the F-shaped frame. The electronic hydraulic device is used for jacking to make the wooden board bend under force to achieve the required curvature requirement.

[0007] Furthermore, two positioning screws are symmetrically arranged in the extension direction of the base plate, and a sliding groove opposite to the position of the positioning screw is opened on the sliding seat. The top end of the positioning screw passes through the sliding groove upward and is screwed with a locking nut; the position of the sliding seat above the base plate can be adjusted, and after the adjustment is completed, it is fixed by the locking nut.

[0008] Furthermore, the sliding seat is U-shaped as a whole, with the opening direction downward, and the two side walls of the U-shaped sliding seat are located on both sides of the base plate and are respectively adjacent to the two side surfaces of the base plate; they play a guiding role for the sliding seat and can prevent the sliding seat from rotating.
