It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0021] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0022] See also Figures 1 to 5 The embodiment of the utility model provides a concrete casting template for infrastructure, which includes a U-shaped template 1, a supporting component 2 and a tensioning wire 3.

[0023] In the embodiments of the present invention, please refer to Figures 1 to 5 The U-shaped formwork 1 is provided with a plurality of support components 2 for supporting the U-shaped formwork 1, and the support component 2 includes a mounting seat 21, the mounting seat 21 is fixedly clamped at the upper edge of the U-shaped formwork 1, and a rotatably connected sleeve 22 is installed on the mounting seat 21, a slidingly connected ground nail 23 is inserted in the sleeve 22, and a threaded fastening screw 24 for fastening the ground nail 23 is installed on the sleeve 22, and a pressing handle 25 is fixedly installed on the side wall of the ground nail 23 to facilitate the insertion of the ground nail 23 into the ground soil layer.

[0024] It should be noted that: before paving the road, the U-shaped template 1 is placed on both sides of the road surface, and the through-wire holes 1b on the corresponding U-shaped template 1 are kept corresponding to each other, the sleeve 22 is rotated so that the sleeve 22 is tilted toward the roadside ground, and the ground nails 23 are inserted outwardly so that the ground nails 23 are inserted into the roadside soil layer, thereby completing the diagonal support of the outer side of the U-shaped template 1, and then the fastening screws 24 are rotated and tightened;

[0025] Among them, a side hole 1a is opened on the end wall of one side of the U-shaped template 1, and a docking rod 11 is fixedly installed on the end wall on the other side of the U-shaped template 1, and the docking rod 11 corresponds to the side hole 1a, so that adjacent U-shaped templates 1 on the same side of the roadside can be docked. Specifically, the docking rod 11 is inserted into the side hole 1a opened in the adjacent U-shaped template 1.

[0026] In the embodiments of the present invention, please refer to Figures 1 to 5 A plurality of evenly distributed tensioning wires 3 are arranged between the U-shaped templates 1 located on both sides of the road surface and corresponding to each other, and a through hole 1b is opened on the end surface of the U-shaped template 1 near the bottom, and a loop 31 is tied to the end of the tensioning wire 3 passing through the through hole 1b, and a tensioning component 4 for tightening the tensioning wire 3 is installed in each of the U-shaped templates 1;

[0027] The tensioning assembly 4 includes a mounting plate 41, which is fixedly mounted on the inner plate wall of the U-shaped template 1, and a rotatably connected threaded rod 42 and two fixedly connected limit rods 43 are installed on the mounting plate 41, and a rocker 421 is fixedly mounted on the threaded rod 42, a sliding plate 44 with a sliding connection is arranged between the two limit rods 43, and the sliding plate 44 is sleeved on the threaded rod 42 through a threaded through hole and is threadedly connected to the threaded rod 42, and a plurality of evenly distributed hooks 45 are fixedly mounted on the lower plate surface of the sliding plate 44, and the hooks 45 correspond one-to-one to the wire holes 1b.

[0028] It should be noted that: after the U-shaped templates 1 on both sides of the road surface are braced by the support assembly, one end of the tension wire 3 is wound into a loop 31 and hooked on the hook 45 in the U-shaped template 1 on one side, and then the other end of the tension wire 3 is passed through the wire holes 1b opened in the U-shaped plates 1 on both sides of the road surface in turn and then wound into a loop 31, and the loop 31 is hooked on the hook 45 in the U-shaped template 1 on the other side;

[0029] Then, the rocker 421 is rotated to make the sliding plate 44 slide along the threaded rod 42 in a direction away from the middle of the road, so that the tension wire 3 is tightened. Therefore, the U-shaped template 1 located on both sides of the road has the support assembly 2 to diagonally support the inner side of the roadbed, and cooperates with the tension wire 3 to tighten the U-shaped template 1 toward the inner side of the roadbed;

[0030] After paving concrete or asphalt on the roadbed, the concrete or asphalt is rolled more compactly by a road roller. At this time, the internal tension generated by the tension wire 3 on the U-shaped template 1 can be balanced, and the lateral pushing stress generated by the road roller on the U-shaped template 1 when rolling the water stabilization can balance the radial component of the pushing force, and cooperate with the support component 2 to improve the anti-overturning ability of the U-shaped template 1;

[0031] After the road is paved, use pliers (or other tools) to cut off the ring 31 on the tension wire 3, and then loosen the fastening screw 24 to slide the inserted ground nail 23 out of the roadside soil layer. The U-shaped formwork 1 can be dismantled later, and the tension wire 3 can be pre-buried in concrete or asphalt to improve the connection strength of the concrete or asphalt pavement.

[0032] The working principle of the concrete pouring template for infrastructure provided by the utility model is as follows:

[0033] Before paving the road, the U-shaped template 1 is placed on both sides of the road surface, and the through holes 1b on the corresponding U-shaped template 1 are kept corresponding to each other. The sleeve 22 is rotated so that the sleeve 22 is tilted toward the roadside ground, and the ground nails 23 are inserted outwardly so that the ground nails 23 are inserted into the roadside soil layer, thereby completing the diagonal support of the outer side of the U-shaped template 1, and then the fastening screws 24 are rotated and tightened;

[0034] After the U-shaped formworks 1 on both sides of the road surface have completed the diagonal bracing through the support assembly, one end of the tension wire 3 is wound into a loop 31 and hooked on the hook 45 in the U-shaped formwork 1 on one side, and then the other end of the tension wire 3 is passed through the wire holes 1b opened in the U-shaped plates 1 on both sides of the road surface in turn and wound into a loop 31, and the loop 31 is hooked on the hook 45 in the U-shaped formwork 1 on the other side, and then the rocker 421 is rotated to make the sliding plate 44 slide along the threaded rod 42 away from the middle of the road, so that the tension wire 3 is tightened. Therefore, the U-shaped formworks 1 on both sides of the road have the support assembly 2 to perform diagonal bracing toward the inner side of the roadbed, and cooperate with the tension wire 3 to tighten the U-shaped formwork 1 toward the inner side of the roadbed, and After paving concrete or asphalt on the roadbed, the concrete or asphalt is rolled more densely by a roller. At this time, the internal tension generated by the tensioning wire 3 on the U-shaped formwork 1 can balance the lateral pushing stress generated by the roller on the U-shaped formwork 1 when rolling the water stabilizer, balancing the radial component of the pushing force, and cooperating with the support component 2 to improve the anti-overturning ability of the U-shaped formwork 1. When the road is paved, use pliers (or other tools) to cut off the ring 31 on the tensioning wire 3, and then loosen the fastening screw 24 to slide the inserted ground nail 23 out of the roadside soil layer. The U-shaped formwork 1 can be demoulded later, and the tensioning wire 3 can be pre-buried in the concrete or asphalt to improve the connection strength of the concrete or asphalt pavement.
