DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The present utility model will now be further described in detail with reference to the accompanying drawings. The drawings are simplified schematic diagrams, which only illustrate the basic structure of the present utility model in a schematic manner. Therefore, they only show the components related to the present utility model.

[0020] Please refer to Figures 1-4 , a device for controlling the slope and flatness of the slope section of a sluice stilling basin, which includes two horizontally arranged parallel round steel bars 1. A longitudinal round steel bar 2 is arranged between the two horizontally arranged round steel bars 1. The two ends of the longitudinal round steel bar 2 are respectively perpendicularly arranged with the horizontally arranged round steel bars 1. The horizontally arranged round steel bars 1 are used to control the flatness of the slope section, and the longitudinal round steel bar 2 controls the slope of the slope section. A support mechanism capable of adjusting the height is arranged below the horizontally arranged round steel bars 1.

[0021] For the specific use state of this device, please refer to Figure 5 . When in use, it is placed on the slope foundation as a whole. At this time, the two ends of the horizontally arranged round steel bar 1 extend horizontally, and the longitudinal round steel bar 2 will be arranged parallel to the slope surface. Then, concrete is poured onto the slope foundation, and the flatness and slope of the slope are judged by the positions of the surface of the concrete and the horizontally arranged round steel bars 1 and the longitudinal round steel bar 2.

[0022] Since the height of the horizontally arranged round steel bar 1 can be adjusted by the support mechanism, it can be concluded that this device can be adjusted according to the slope and has a wide range of applications.

[0023] In the solution of the present utility model, the longitudinal round steel bar 2 includes a hinge cylinder 21 and a hinge rod 22. One end of the hinge rod 22 is inserted and pulled out with the hinge cylinder 21. A rotatable rotating cylinder 3 is arranged on the circumference of the horizontally arranged round steel bar 1. The ends of the hinge cylinder 21 and the hinge rod 22 are both fixed on the rotating cylinder 3 by welding.

[0024] That is to say, the ends of the longitudinal round steel bar 2 (the hinge cylinder 21 and the hinge rod 22) can rotate on the horizontally arranged round steel bar 1 through the rotating cylinder 3. With the height adjustment of the support mechanism, the rotation and insertion and pulling of the hinge cylinder 21 and the hinge rod 22 can meet the adjustment, making it suitable for controlling the slopes and flatnesses of different slopes.

[0025] Specifically, the support mechanism includes a support cylinder 4 and a screw rod 6 inside the support cylinder 4. A matching spiral jack 5 is arranged on the circumference of the screw rod 6. The bottom port of the support cylinder 4 is always in contact with the surface of the spiral jack 5. The rotation of the spiral jack 5 drives the support cylinder 4 to rise and fall.

[0026] In addition, the support mechanism further includes an arc-shaped support plate 41 at the top of the support cylinder 4. Both ends of the arc-shaped support plate 41 are provided with upward-extending support blocks 42. The surface of the support blocks 42 is fixedly connected with the horizontally arranged round steel bar 1. Among them, the length of the arc-shaped support plate 41 is greater than the length of the rotating cylinder 3, and the rotating cylinder 3 is never in contact with the inner wall of the arc-shaped support plate 41.

[0027] Through the provided arc-shaped supporting plate 41 and supporting block 42, it is possible to directly contact and support the horizontal round steel. Therefore, during the height change process, the rotation of the rotating cylinder 3 does not interfere with the arc-shaped supporting plate 41. During the height adjustment process, the lifting of the horizontal round steel 1 changes the angle of the longitudinal round steel 2 at any time, enabling it to adapt to the slopes of different slope sections and facilitating the control of the slope during the pouring process. Since the horizontal round steel 1 is always horizontal, it is possible to control the flatness of the slope section and ensure the construction quality.

[0028] As a preferred solution, before pouring the slope section, it is necessary to set up steel bars on the slope foundation. After the steel bars are set up, the device is vertically fixed. To ensure the stability of the device, a base 7 is provided at the bottom of the screw rod 6, and a fixing rod is provided below the base 7. Multiple elastic buckles 8 are provided at the bottom of the fixing rod. The elastic buckles 8 cooperate with the built-in steel bar 9. The cross-section of the elastic buckle 8 is circular and there is an opening at the bottom. During installation, only need to slightly press down the horizontal round steel. After pressing, the elastic buckle 8 covers the circumference of the steel bar 9 through the opening at the bottom, thus ensuring a vertically stable setting.

[0029] After setting up, concrete can be poured on the slope foundation. When the concrete evenly contacts the horizontal round steel 1 and the longitudinal round steel 2, it indicates that the flatness and slope of the slope section are well controlled. Then, the overall structure is taken out. When taking out, pull up the horizontal round steel upward to separate and pull out the elastic buckle 8 from the steel bar 9, and it can also be recycled. After the overall device is taken out, the concrete can flow by itself or be filled again.

[0030] The construction content of the Guangzhou Daaolao Barrage Reinforcement and Reconstruction Project is to reinforce and reconstruct the Daaolao Barrage. The stilling basin slope section of this construction is from pile number BZ0+000 to BZ0+202.05, with a length of 40.21 m in the water flow direction. After using this device for construction, the appearance quality of the project has been greatly improved, the flatness and slope of the slope surface have been ensured, the scheduled planned construction period has been shortened, and good economic and social benefits have been brought.

[0031] Obviously, the above embodiments are only examples clearly described and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
