Description

Technical Field

[0001] The present application relates to the technical field of wall crack control, and in particular to a system and method for controlling cracks on the tensioned short sides of a zigzag wall of a storage ring tunnel. Background Art

[0002] Storage ring tunnels are a crucial component of high-energy synchrotron radiation source projects, used to store and accelerate electron beams to produce high-energy synchrotron radiation. Storage ring tunnels typically maintain a high vacuum environment to protect the electron beam from external interference during acceleration. They are also equipped with a series of advanced magnets and control systems to precisely guide and stabilize the movement of the electron beam. These tunnels are widely used in research across a wide range of fields, including materials science, biomedicine, energy, and the environment.

[0003] There are concrete walls on both sides of the storage ring tunnel, and the outer concrete wall is generally designed to be zigzag-shaped. After the concrete is poured and formed, in order to reduce the occurrence of cracks in the concrete wall, pipes will be embedded in the concrete wall before pouring the concrete. Then, after the concrete solidifies and the outer forming formwork is removed, pre-tightened steel bars are passed through the embedded pipes, and prestressed tensioning of the concrete wall is achieved by pulling at both ends. When prestressing the long side of the zigzag wall, although expansion joints are reserved, the long side wall will also apply tension to the short side walls at both ends, causing the short side wall to twist, which increases the possibility of cracks in the short side wall. Summary of the Invention

[0004] In order to reduce the impact on the short sides of the wall while prestressing the long sides of the wall to reduce the possibility of cracks on the short side walls, the present application provides a storage ring tunnel serrated wall tensioning short side crack control system and method.

[0005] The present application provides a storage ring tunnel serrated wall tension short side crack control system and method using the following technical solutions:

[0006] In a first aspect, the present application provides a method for controlling cracks on the short sides of a serrated wall of a storage ring tunnel during tensioning.

[0007] A method for controlling cracks on the short sides of a zigzag wall of a storage ring tunnel, comprising:

[0008] Removing the long side forming template outside the long side of the wall to be tensioned to obtain the exposed long side of the wall to be tensioned;

[0009] Install guide templates on both sides of the exposed long side of the wall to be tensioned, and connect the guide templates on both sides to form a guide whole, and the guide whole is rolledly connected to the long side of the wall to be tensioned;

[0010] The guide structure is connected to the short side forming template outside the short side of the adjacent wall to obtain a protective structure, and an operation hole is reserved on the short side forming template;

[0011] Remove the blocking structure at the operation hole, then pass prestressed tendons through the operation hole on the long side of the wall to be tensioned, and then perform tensioning operations on the two ends of the prestressed tendons to complete the tensioning of the long side of the wall to be tensioned.

[0012] By adopting the above technical solution, the long side forming template on the outside of the long side of the wall to be tensioned is first removed to obtain the exposed long side of the wall to be tensioned; then, guide templates are installed on both sides of the exposed long side of the wall to be tensioned, and the guide templates on both sides are connected to form a guide whole, and the guide whole is connected to the long side of the wall to be tensioned in a rolling manner; then, the guide whole is connected to the short side forming template on the outside of the short side of the adjacent wall to obtain a protective structure, and an operation hole is reserved on the short side forming template; finally, the blocking structure at the operation hole is removed, and then a pre-installed structure is passed through the operation hole on the long side of the wall to be tensioned. Stress tendons are then tensioned at the two end outlets of the prestressed tendons to complete the tensioning of the long side of the wall to be tensioned; the designed storage ring tunnel serrated wall tensioning short side crack control method, through the protective structure obtained by fixing the guide whole and the short side forming template, can make the protective structure replace the short side of the wall to bear torque, and then when the long side of the wall to be tensioned is tensioned, the angle between the long side of the wall to be tensioned and the short side of the wall remains unchanged, thereby avoiding the situation where the short side of the wall is subjected to torque during the prestressing process of the long side of the wall to be tensioned, resulting in an increase in wall cracks.

[0013] In a specific feasible implementation scheme, before inserting the prestressed tendons, the two protective structures located at both ends of the long side of the wall to be tensioned are guided for displacement so that the displacement direction of the protective structures is parallel to the force direction of the prestressed tendons.

[0014] By adopting the above technical solution, the displacement direction of the protective structure can be further restricted so that the displacement direction of the protective structure is parallel to the force direction of the prestressed tendons, thereby reducing the possibility of torsional deformation of the short side of the wall.

[0015] In a specific feasible implementation plan, while the long side forming formwork on the outside of the long side of the wall to be tensioned is removed, a fixed formwork is installed on the outside of the long side of the wall at the next construction position, so that the fixed formwork is fixed to the long side of the wall at the next construction position, and before the prestressed tendons are inserted, the fixed formwork is connected to the short side forming formwork on the outside of the short side of the adjacent wall.

[0016] By adopting the above technical solution, the tension applied by the short side of the wall to the long side of the wall at the next construction position can be transformed from a vertical direction to a parallel direction with the long side of the wall at the next construction position through a fixed formwork, thereby reducing the possibility of torsion between the short side of the wall and the long side of the wall at the next construction position.

[0017] In a second aspect, the present application provides a storage ring tunnel serrated wall tensioning short side crack control system.

[0021] The guide unit and the short side forming template form a protective cavity that covers the long side end portion of the wall to be tensioned and the short side of the wall.

[0022] By adopting the above technical solution, the long side forming template on the outside of the long side of the wall to be tensioned is first removed to obtain the exposed long side of the wall to be tensioned; then, guide templates are installed on both sides of the exposed long side of the wall to be tensioned, and the guide templates on both sides are connected to form a guide whole, and the guide whole is rolledly connected to the long side of the wall to be tensioned; then, the guide whole is connected to the short side forming template on the outside of the short side of the adjacent wall to obtain a protective structure, and an operation hole is reserved on the short side forming template; finally, the blocking structure at the operation hole is removed, and then the Prestressed tendons are passed through the operating holes on the long sides of the wall to be tensioned, and then tensioning operations are carried out at the outlet parts at both ends of the prestressed tendons to complete the tensioning of the long sides of the wall to be tensioned; the designed storage ring tunnel serrated wall tensioning short side crack control system can form a protective cavity that covers the long side and short side of the wall to be tensioned through the guiding whole and the short side forming template, thereby reducing the deformation curvature of the short side of the wall to be tensioned during prestressing, reducing the possibility of torsion of the short side of the wall, and reducing the occurrence of cracks on the short side of the wall.

[0023] In a specific embodiment, the guide body comprises:

[0024] Two guide templates, each of which is connected to a short-side forming template. A plurality of contact rollers are rotatably connected to the guide template. The contact rollers are used to be in rolling connection with the long sides of the wall to be tensioned, and the rotation axis of the contact rollers is perpendicular to the displacement direction of the guide template.

[0025] A plurality of connecting rods are provided, and both ends of the connecting rods are respectively detachably fixedly connected to the two guide templates.

[0026] By adopting the above technical solution, the designed guide whole can cooperate with the short side forming template to control the cracks on the short side of the wall through the guide template and the contact roller, and at the same time, it can reduce the damage to the outer surface of the long side of the wall to be tensioned during the prestressing process of the long side of the wall to be tensioned; the two guide templates can be connected by the connecting rod to form a structural whole.

[0027] In a specific embodiment, the short side forming template, the guide template and the internal corner are detachably fixedly connected with at least one diagonal support reinforcement rod.

[0055] The implementation principle of a short side crack control system for tensioning a serrated wall of a storage ring tunnel according to an embodiment of the present application is as follows: first, the long side forming template on the outside of the long side 01 of the wall to be tensioned is removed to obtain the exposed long side 01 of the wall to be tensioned; then, a guide template 11 is installed on both sides of the exposed long side 01 of the wall to be tensioned, and the guide templates 11 on both sides are connected to form a guide whole 1, and the guide whole 1 is rolledly connected to the long side 01 of the wall to be tensioned; then, the guide whole 1 is connected to the short side forming template 2 on the outside of the short side 02 of the adjacent wall to obtain a protective structure, and an operation hole 21 is reserved on the short side forming template 2; finally, the blocking structure at the operation hole 21 is removed, and then prestressed tendons are passed through the operation hole 21 on the long side 01 of the wall to be tensioned, and then tensioning operations are performed on the two end outlets of the prestressed tendons to complete the tensioning of the long side 01 of the wall to be tensioned.

[0056] In a second aspect, an embodiment of the present application discloses a method for controlling cracks on the short sides of a serrated wall of a storage ring tunnel during tensioning.

[0058] S1: removing the long side forming template outside the long side 01 of the wall to be tensioned to obtain the exposed long side 01 of the wall to be tensioned;

[0059] S2: Install guide templates 11 on both sides of the exposed long side 01 of the wall to be tensioned, and connect the guide templates 11 on both sides to form a guide body 1, and the guide body 1 is rolledly connected to the long side 01 of the wall to be tensioned;

[0063] Furthermore, in order to further limit the displacement direction of the protective structure so that the displacement direction of the protective structure is parallel to the force direction of the prestressed tendons, thereby reducing the possibility of torsional deformation of the short side 02 of the wall, before the prestressed tendons are inserted in step S4, the two protective structures located at both ends of the long side 01 of the wall to be tensioned are guided for displacement so that the displacement direction of the protective structure is parallel to the force direction of the prestressed tendons, thereby further limiting the displacement direction of the protective structure so that the displacement direction of the protective structure is parallel to the force direction of the prestressed tendons, thereby reducing the possibility of torsional deformation of the short side 02 of the wall.

[0064] Furthermore, in order to transform the tension applied by the short side 02 of the wall on the long side 03 of the wall at the next construction position from a vertical direction through the fixed template 6 into a direction parallel to the long side 03 of the wall at the next construction position, thereby reducing the possibility of torsion between the short side 02 of the wall and the long side 03 of the wall at the next construction position, in step S1, while the long side forming template outside the long side 01 of the wall to be tensioned is removed, the fixed template 6 is installed outside the long side 03 of the wall at the next construction position, so that the fixed template 6 is fixed to the long side 03 of the wall at the next construction position, and before the prestressed tendons are inserted, the fixed template 6 is connected to the short side forming template 2 outside the adjacent short side 02 of the wall, thereby transforming the tension applied by the short side 02 of the wall on the long side 03 of the wall at the next construction position from a vertical direction through the fixed template 6 into a direction parallel to the long side 03 of the wall at the next construction position, thereby reducing the possibility of torsion between the short side 02 of the wall and the long side 03 of the wall at the next construction position.

[0065] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
