[0026] The connecting tube 3 is installed in the slot 203. The upper end of the metal screw 104 passes through the connecting tube 3 and is fixedly connected to the connecting tube 3 by an external nut.
[0027] In the above embodiment, multiple semi-circular plastic formwork templates are connected end-to-end to achieve long-distance laying. The cover plate 102 is fixed to the upper side of the template body 101, which can effectively prevent concrete from entering and contaminating the inside of the template body 101 during construction, thereby increasing the weight of the template body 101 and affecting the subsequent construction progress. Based on the threaded connection between the lower end of the metal screw 104 and the pre-embedded nut 103, and the fixed connection between the upper end of the metal screw 104 and the connecting pipe 3 through the external nut, the height of the template body 101 can be adjusted according to the construction conditions to meet the construction requirements. The fixing bracket clamp can effectively fix the external tool rail 4 on the fixing bracket. At the same time, the anti-floating screw 202 can control the floating of the template body 101 during the concrete pouring process, so that the ditch template does not undergo horizontal displacement and dimensional changes, achieving high-standard construction goals. Therefore, this installation system is not easily restricted in actual construction, and the construction laying speed is fast and the laying efficiency is high, which effectively improves the construction progress and has the characteristics of convenient installation and high construction efficiency.
[0028] In some embodiments, the inner side of the template body 101 is provided with a groove 105, and the lower side of the cover plate 102 is connected with a reinforcing rib 106 that matches the groove 105.
[0029] In the above embodiment, by utilizing the reinforcing rib 106 provided on the lower side of the cover plate 102 and matching the groove 105, the position of the cover plate 102 on the template body 101 can be quickly positioned, realizing the quick and accurate installation of the cover plate 102 on the template body 101. It should be noted that in this embodiment, each template body 101 is provided with three cover plates 102 on its upper side, and each cover plate 102 has a threaded hole in the middle that matches the metal screw 104, so that each metal screw 104 can be tightened with the corresponding pre-embedded nut 103.
[0030] In some embodiments, self-tapping screws are also provided around the cover plate 102, which pass through the cover plate 102 and are connected to the outer wall of the template body 101 to fix the cover plate 102 to the template body 101.
[0031] In the above embodiment, the cover plate 102 is fixed to the template body 101 by self-tapping screws around the cover plate 102, which further enhances the sealing performance of the connection between the cover plate 102 and the template body 101.
[0032] In some embodiments, a fixing buckle 107 is also included. Each semi-circular drainage ditch plastic template has multiple connecting holes 108 at both ends.

[0033] In the above embodiment, each semi-circular ditch plastic template has three connecting holes 108 at both ends. The three connecting holes 108 are arranged in a triangle. Based on the fixing buckles 107 that match the connecting holes 108 one by one, the two adjacent semi-circular ditch plastic templates can be locked and firmly fixed, realizing the rapid splicing of long-distance ditch templates.
[0034] In some embodiments, the support body 201 is threaded with two anti-floating screws 202, and the lower ends of the two anti-floating screws 202 abut against the two sides of the upper side of the cover plate 102, respectively.
[0035] In the above embodiment, the two anti-floating screws 202 are located on both sides of the cover plate 102 and abut against the upper side of the cover plate 102. This can prevent the formwork body 101 from horizontal displacement during the concrete pouring process and effectively prevent the formwork body 101 from floating.
[0036] In some embodiments, the slot 203 is located between two anti-floating screws 202.
[0037] In the above embodiment, by setting the slot 203 between the two anti-floating screws 202, that is, the connecting pipe 3 is located between the two anti-floating screws 202, the metal screw 104 is located between the two anti-floating screws 202, thus ensuring the stability of the formwork body 101 during the concrete pouring process.
[0038] In some embodiments, the slot 203 includes two L-shaped support plates that are disposed opposite to each other and fixed to the bracket body 201.
[0039] In the above embodiment, the slot 203 is composed of two L-shaped support plates arranged opposite each other, which facilitates the disassembly and assembly of the connecting pipe 3 and further improves construction efficiency.
[0040] In some embodiments, the fixing clamp includes a first clamp 204, a second clamp 205, a fixing rod 206, a fixing bolt 207, and a fixing nut 208. The first clamp 204 and the fixing rod 206 are fixed to the bracket body 201. The second clamp 205 is arranged opposite to the first clamp 204 and forms an arc-shaped groove with the bracket body 201 that matches the external tool rail 4. One end of the second clamp 205 is hinged to the fixing rod 206, and a fixing groove 209 is provided in the middle of the second clamp 205.

[0046] Then, multiple fixed supports are placed at the installation positions of the track bed tool rail 4, and the tool rail 4 is fixed to the track bed using fixed support clamps. According to the tooling requirements, the ditch template is placed on the fixed supports. At the same time, the upper end of the metal screw 104 is connected and fixed to the connecting pipe 3 through the external nut. The height of the template body 101 can be adjusted according to different construction conditions to meet the construction requirements. Finally, the relative position between the anti-buoyancy screw 202 and the cover plate 102 is adjusted to ensure that the buoyancy of the template body 101 can be effectively controlled during the concrete pouring process, so that the template body 101 does not undergo horizontal displacement, thus perfectly achieving the construction goal.
