Using custom-made steel formwork, however, requires significant material input due to varying drainage hole sizes for different ditch dimensions, leading to excessively high costs. A similar approach is proposed in patent CN202120437107.8, which describes a mold for drainage holes in cast-in-place concrete drainage ditch covers. This mold includes a module for forming the drainage holes, a square cylinder fitted over the module, and a retaining element positioned on the upper surface of the module. The utility model provides a mold for drainage holes in cast-in-place concrete covers, which makes the distribution of drainage holes on the playground more balanced, reduces the error of manual measurement, and improves the aesthetics. However, the mold for drainage holes in cast-in-place concrete covers is difficult to dismantle, is easily damaged during dismantling, and has low construction efficiency. The mold consists of a column, a U-shaped clamp connecting to the square tube, a connecting column with one end connected to the U-shaped clamp, and a measuring component connected to the other end of the connecting column. The measuring component is located on the outer edge of the cast-in-place concrete. A hinged column is provided on the retaining column, and the hinged column is connected to another mold via a hinged rod. The lower end face of the retaining column contacts the upper end face of the square tube. Utility Model Content

A lever hinge shaft 11 is fixed on the upper end of the longitudinal tapered support 8. A hinge threaded sleeve 10 is hinged to the upper end of the longitudinal tapered support 8 through the lever hinge shaft 11.

[0025] The working principle and beneficial effects of this embodiment are as follows: The bottom of the lever support base 1 is formed by welding together two long and two short steel pipes, namely the lower crossbar 7 of the support and the lower connecting rod 9. The lower connecting rod 9 is provided with a connecting hole for connection when using the sliding base platform 5. The vertical support part of the lever bracket base 1 is made of two steel pipes on each of the left and right ends, which are welded to the bottom steel pipe. The steel pipes are connected by steel bars to form a stable whole, namely the longitudinal tapered bracket 8. The vertical steel pipes on both sides of the vertical support part of the lever bracket base 1 are spaced 10cm apart and connected by steel bars. The upper end of the longitudinal tapered bracket 8 is hinged to the lever hinge shaft 11 and a hinge threaded sleeve 10 is set, so that the hinge threaded sleeve 10 can be used as a sliding support device, and thus be used as a sliding support lever support point.

[0026] Example 3: As Figure 1 — Figure 7 As shown, a device for removing the template of the drainage hole of a cast-in-place drainage ditch cover is provided, wherein the inner wall of the hinged threaded sleeve 10 is connected to the threaded lever 2 through a threaded engagement.

[0027] The working principle and beneficial effects of this embodiment are as follows: by connecting the threaded lever 2 to the inner wall of the hinged threaded sleeve 10, it is convenient to adjust the position of the threaded lever 2 on the hinged threaded sleeve 10, and then change the torque of the lever according to the actual use scenario and environment, so as to conveniently adjust the force condition and effectively adjust the force-saving use according to the use scenario.

[0028] Example 4: Figure 1 — Figure 7 As shown, a device for removing the template of the drainage hole of a cast-in-place drainage ditch cover is provided. The inner side of the outer wall of the threaded lever 2 is provided with a groove, and the upper collar 13 is fitted into the groove of the threaded lever 2.

[0029] The working principle and beneficial effects of this embodiment are as follows: By providing a groove on the inner side of the outer wall of the threaded lever 2, the upper collar 13 is fitted into the groove of the threaded lever 2, effectively securing the upper collar 13 while also facilitating its freedom of movement and making it convenient to connect with the rebar hook 3. There are many ways to fit the upper collar 13 into the groove, and installation can be performed through disassembly and assembly.
