The hydraulic module includes a first hydraulic screw 21 and a second hydraulic screw 22, wherein the upper end of the first hydraulic screw 21, one end of the second hydraulic screw 22 and a connecting portion are hinged, the lower end of the first hydraulic screw 21 is hinged to the upper end of the center bottom form 11, and the other end of the second hydraulic screw 22 is hinged to another connecting portion. Here, the first hydraulic screw 21 may also be a diagonal hydraulic screw, and the second hydraulic screw 22 may also be a horizontal hydraulic screw. The length of the center bottom form 11 may be 1 to 3 m, for example, 1.5 m, 1.8 m, 2.3 m, 2.6 m or 2.9 m.

[0031] In this exemplary embodiment, the upper end of the first hydraulic screw 21, one end of the second hydraulic screw 22 and a connecting portion are hinged by a hinge ear 3, the lower end of the first hydraulic screw 21 and the upper end of the center bottom mold 11 are hinged by the hinge ear 3, and the other end of the second hydraulic screw 22 and another connecting portion are hinged by the hinge ear 3 to fix the mold frame.

[0032] In the present exemplary embodiment, the side mold 12 includes a first L-section 121 and a second L-section 122 connected sequentially from top to bottom. The first L-section 121 may have a height of 0.35 to 0.7 m, for example, 0.4 m, 0.45 m, 0.53 m, 0.66 m, or 0.69 m, and a length of 0.21 to 0.39 m, for example, 0.23 m, 0.26 m, 0.33 m, or 0.37 m, and the second L-section 122 may have a height of 0.7 to 1.05 m, for example, 0.73 m, 0.82 m, 0.86 m, 0.93 m, 0.99 m, or 1.03 m, and a length of 0.87 to 1.05 m, for example, 0.89 m, 0.93 m, 0.99 m, or 1.03 m.

[0033] In this exemplary embodiment, the hydraulic center ditch formwork system may also include a tugboat, which can move the formwork to a predetermined position. Here, a tugboat is installed at the bottom of the formwork to be towed to a predetermined position by a loader or excavator, the position of the formwork is adjusted, and the formwork is fixed by braking. The formwork is moved laterally to a predetermined plane position by the screw rod of the suspended formwork, and then the elevation of the formwork is adjusted to a predetermined elevation by screwing the nut on the screw rod, and the transverse screw is adjusted to fix the formwork system. The position of the formwork is accurately adjusted and controlled by fine-tuning bolts, and the transverse drainage pipe reserved for the road surface is led out and adjusted to be close to the formwork surface. The end of the drainage pipe is closed with a geotextile, and the positioning steel bar is installed to fix the pipe position.

[0034] In this exemplary embodiment, the hydraulic center ditch formwork system may further include a support member, which is located outside the formwork and can support and reinforce the formwork. Here, in order to enhance the overall stability of the formwork during the pouring of concrete, steel bars may be implanted and diagonal braces may be installed on the bottom plate pavement concrete outside the formwork for reinforcement, and then a release agent may be applied, and after inspection and verification, concrete pouring may be prepared.

[0035] In this exemplary embodiment, due to the small cross-section of the groove, it is not possible to directly use a tank truck to enter the mold. It is necessary to use a thin steel plate to make a material distribution trough to facilitate the guidance of concrete into the mold so that the concrete surface in the mold rises evenly. The concrete is poured evenly in layers and formed in one time. The slump is controlled between 14 and 16 cm. Vibrating rod insertion tamping can be used, and steel bars or embedded parts must not be touched. After the concrete pouring is completed, geomembrane covering and water sprinkling are used for moisturizing maintenance, and the maintenance time is not less than 12 hours. When closing the mold, first remove the diagonal brace hydraulic screw, that is, the first hydraulic screw 21, and then rotate the horizontal hydraulic screw, that is, the second hydraulic screw 22, to separate the template from the concrete. Finally, the self-provided lifting equipment on site lifts the rotating template on both sides to completely demold. After closing the mold, fix the mold closing state on site, install the tugboat, and then use the equipment to move to the next casting section.

[0036] In summary, the advantages of the present invention include at least one of the following:

[0037] (1) The hydraulic center ditch formwork system provided by the utility model integrates the large formwork and the positioning system into a whole through the formwork frame, replacing the traditional small steel formwork and square wood support scattered assembly construction, and the formwork frame is moved to the next group as a whole through mechanical traction and tugboat.
