[0020] Example 1 See Figure 1 A convenient pre-drilling mold for circular road inspection wells includes a corrugated pipe 1 and a support mechanism 3. The corrugated pipe 1 can be made of high-strength plastic or composite material, which is not only high in strength but also recyclable, reducing environmental pollution. The corrugated pipe 1 has strong pressure resistance and fatigue resistance, can disperse stress, has high pressure bearing capacity, and is not easy to crack under high frequency expansion and contraction deformation. See Figure 1 and Figure 2 The support mechanism 3 includes two wooden strips 301 of the same length. An elastic sealing ring 2 is installed inside the corrugated pipe 1. The length of each wooden strip 301 is equal to the inner diameter of the corrugated pipe 1 minus the thickness of the elastic sealing ring 2. The two wooden strips 301 are fixedly connected inside the corrugated pipe 1 in a cross shape, and abut against the elastic sealing ring 2. The two cross-shaped wooden strips 301 support the corrugated pipe 1, preventing it from deforming under the pressure of concrete. The elastic sealing ring 2 not only prevents the wooden strips 301 from damaging the corrugated pipe 1, but also... The inner wall of pipe 1 is worn, but it can also absorb the thermal expansion stress during concrete curing. The center of each of the two wooden strips 301 is provided with a first screw hole 302 of the same size. The two wooden strips 301 are connected by bolts and the first screw hole 302. The two wooden strips 301 are provided with a first marking line 303 at the middle position along their length direction to facilitate alignment with the first screw hole 302 on the two wooden strips 301 and facilitate fixed installation. Rubber sealing rings are provided at both ends of the corrugated pipe 1 to prevent concrete from seeping into the corrugated pipe 1.

[0021] The manufacturing process and working principle of the pre-reserved hole mold in this embodiment are as follows: Based on the actual needs of the construction site and combined with construction experience, a certain length of corrugated pipe 1 is cut, and an elastic sealing ring 2 is installed inside the corrugated pipe 1. Two wooden strips 301 with a length equal to the inner diameter of the corrugated pipe 1 minus the thickness of the elastic sealing ring 2 are cut and fixed in a cross shape inside the corrugated pipe 1, so that the two wooden strips 301 abut against the elastic sealing ring 2. The two cross-shaped wooden strips 301 are used to support the corrugated pipe 1 so that it will not be deformed by the pressure of concrete, thereby improving the mold accuracy, making the size of the pre-reserved hole more accurate, and improving the forming quality of the pre-reserved hole. The two wooden strips 301 are fixed together with bolts. Finally, rubber sealing rings are installed at both ends of the corrugated pipe 1 to ensure good sealing and prevent concrete from seeping into the corrugated pipe 1. In this way, the pre-reserved hole mold is completed. This mold uses fewer types of raw materials, is easy to assemble, can be quickly formed, improves construction efficiency, and the mold can be reused, which can reduce construction costs.

[0022] Example 2 The difference between Example 2 and Example 1 lies only in the support mechanism 3. However, in this example, the support mechanism 3 is also fixed in a cross shape inside the corrugated pipe 1 to support the corrugated pipe 1 so that it will not be deformed by the pressure of the concrete.

[0023] See Figure 1 and Figure 3 The support mechanism 3 includes four L-shaped wooden frames 304 of the same size. The four L-shaped wooden frames 304 are fixedly connected in a cross shape inside the corrugated pipe 1. The four L-shaped wooden frames 304 include a first frame 3041 and a second frame 3042 that are perpendicular to each other. A second screw hole 3043 is provided at the connection between the first frame 3041 and the second frame 3042. The four L-shaped wooden frames 304 are connected by bolts and the second screw hole 3043. A second marking line 3044 is provided at the middle position of the first frame 3041 and the second frame 3042 along their length direction to facilitate alignment with the second screw hole 3043 on the four L-shaped wooden frames 304 and facilitate fixed installation.

[0024] The manufacturing process and working principle of the pre-reserved hole mold in this embodiment are as follows: Based on the actual needs of the construction site and combined with construction experience, a certain length of corrugated pipe 1 is cut, and an elastic sealing ring 2 is set inside the corrugated pipe 1. Four L-shaped wooden frames 304 are cut, and the distance from one end of each of the two right-angled sides to the center of the second screw hole is equal to half the inner diameter of the corrugated pipe minus the thickness of the elastic sealing ring 2. The four L-shaped wooden frames 304 are fixed together into a cross-shaped structure through the second screw hole 3043 and bolts, and fixed inside the corrugated pipe 1 so that the four L-shaped wooden frames 304 abut against the elastic sealing ring 2 to support the corrugated pipe 1 so that it will not be deformed by the pressure of concrete. Finally, rubber sealing rings are set at both ends of the corrugated pipe 1 to prevent concrete from seeping into the corrugated pipe 1. In this way, the pre-reserved hole mold is completed.

[0025] In this embodiment, the support mechanism 3 is assembled from four L-shaped wooden frames 304, which facilitates assembly and subsequent demolding. During assembly and disassembly, the pieces can be removed and placed separately, enabling rapid molding and improving construction efficiency. Both the corrugated pipe 1 and the support mechanism 3 are reusable. Moreover, when a certain L-shaped wooden frame 304 becomes damaged and affects its use after a period of use, only that L-shaped wooden frame 304 needs to be replaced, without replacing the entire support mechanism 3, which can further reduce construction costs.

[0026] Example 3 The only difference between Example 3 and Example 1 is the support mechanism 3. In this example, the support mechanism 3 is fixed inside the corrugated pipe 1 in a star-shaped structure to support the corrugated pipe 1 so that it will not be deformed by the pressure of the concrete.

[0027] See Figure 4 and Figure 5 The support mechanism 3 includes three wooden strips 301 of the same length, which are fixedly connected in a star-shaped pattern inside the corrugated pipe 1. Each of the three wooden strips 301 has a first screw hole 302 of the same size at its center. The three wooden strips 301 are connected by bolts and the first screw holes 302. Each of the three wooden strips 301 has a first marking line 303 at the middle position along its length to facilitate alignment with the first screw holes 302 on two wooden strips 301, which facilitates the fixed installation.

[0028] The manufacturing process and working principle of the pre-reserved hole mold in this embodiment are as follows: Based on the actual needs of the construction site and combined with construction experience, a certain length of corrugated pipe 1 is cut, and an elastic sealing ring 2 is set inside the corrugated pipe 1. Three wooden strips 301 with a length equal to the inner diameter of the corrugated pipe 1 minus the thickness of the elastic sealing ring 2 are cut and fixed inside the corrugated pipe 1 in a cross shape, so that the three wooden strips 301 abut against the elastic sealing ring 2. The three cross wooden strips 301 are used to support the corrugated pipe 1 so that it will not be deformed by the pressure of concrete, thereby improving the mold accuracy, making the size of the pre-reserved hole after molding more accurate, and improving the molding quality of the pre-reserved hole. The three wooden strips 301 are fixed together with bolts. Finally, rubber sealing rings are set at both ends of the corrugated pipe 1. The sealing performance is good and prevents concrete from seeping into the corrugated pipe 1. In this way, the pre-reserved hole mold is completed.

[0029] In this embodiment, a support mechanism 3 with a star-shaped structure is assembled from three wooden strips 301. This support mechanism 3 has higher support strength and better support effect on the corrugated pipe 1. It can more effectively prevent the corrugated pipe 1 from deforming under the pressure of concrete, thereby enhancing the pressure-bearing capacity of the corrugated pipe 1, and thus making the mold more precise and the reserved hole size after molding more accurate.
