Detailed Embodiment

[0016] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0017] As Figure 1 —shown in FIG. 2, the present invention is an integral rapid construction formwork for highway drainage ditches and cable ditches, including a cable ditch formwork 1, a drainage ditch formwork 2 and side formworks 3; the cable ditch formwork 1, the drainage ditch formwork 2 and the side formworks 3 are fixedly connected to a lifting oil cylinder 5 through a transverse movement oil cylinder 4 and can be horizontally moved, and the lifting oil cylinder 5 is vertically movably sleeved on the columns of a water ditch and cable ditch trolley 6. The cable ditch formwork 1 and the drainage ditch formwork 2 of the integral rapid construction formwork for highway drainage ditches and cable ditches adopt a split structure, which can achieve good demoulding effect and no damage to the edges and corners of the ditch wall.

[0018] The cable ditch formwork 1 is an overall rectangular box body, which is composed of a middle box girder 7, a left cable ditch formwork 8, a right cable ditch formwork 9 and a middle box girder connecting column 10. The middle box girder 7 is an isosceles trapezoidal box body, and a middle box girder connecting column 10 is arranged on the upper part of the middle box girder 7. The middle box girder 7 is pin-connected to the transverse movement oil cylinder 4 through the middle box girder connecting column 10. The left cable ditch formwork 8 and the right cable ditch formwork 9 are right trapezoidal box bodies, and the left cable ditch formwork 8 and the right cable ditch formwork 9 are respectively arranged on both sides of the middle box girder 7 and are slidably connected to the middle box girder 7.

[0019] The left cable ditch formwork 8 and the right cable ditch formwork 9 can be slidably connected to the middle box girder 7 in various forms. The present invention preferably adopts: the left cable ditch formwork 8 and the right cable ditch formwork 9 are respectively slidably connected to the middle box girder 7 through sliding rods 18. Grooves communicated with their interiors are respectively arranged on the side surfaces of the left cable ditch formwork 8 and the right cable ditch formwork 9 that are in contact with the middle box girder 7 and on both sides of the middle box girder 7. The sliding rods 18 pass through the grooves, and bearings that are respectively in contact with the inner surfaces of the left cable ditch formwork 8, the right cable ditch formwork 9 and the middle box girder 7 are arranged at both ends of the sliding rods 18. When the cable ditch formwork 1 is demoulded, the bottoms of the left cable ditch formwork 8 and the right cable ditch formwork 9 can move towards the bottom of the middle box girder 7 under the action of gravity through the sliding rods 18 to ensure the forming effect of the cable ditch after demoulding.

[0020] The drainage ditch formwork 2 is a rectangular box as a whole, and is composed of a diagonal bracing bolt 11, a connecting rod 12, a left drainage ditch formwork 13, and a right drainage ditch formwork 14. The left drainage ditch formwork 13 and the right drainage ditch formwork 14 are right-angled trapezoidal boxes, and the left drainage ditch formwork 13 and the right drainage ditch formwork 14 are connected by the diagonal bracing bolt 11. One end of the diagonal bracing bolt 11 vertically passes through the right drainage ditch formwork 14 and is fixedly connected to the left drainage ditch formwork 13, and the other end is provided with a nut 15 that can abut against the upper surface of the right drainage ditch formwork 14. A baffle 16 is also fixedly provided on the upper part of the left drainage ditch formwork 13 near the right cable trench formwork 9, and a gap for pouring concrete is provided between the baffle 16 and the right cable trench formwork 9. The upper part of the right formwork 14 of the drainage ditch is connected to the pin shaft of the transverse cylinder 4 through the right formwork connecting column 17 of the drainage ditch. A connecting rod 12 is also provided on the upper part of the right formwork 14 of the drainage ditch near the side of the column. The right formwork 14 of the drainage ditch is rotatably connected to the side formwork 3 of the rectangular box structure through the connecting rod 12. A gap for pouring concrete is provided between the right formwork 14 of the drainage ditch and the side formwork 3.

[0021] When setting the mold: the first step is to move the ditch and cable trench trolley 6 to the pouring position, and align the end face of the side mold 3 with the parting line by horizontally moving the transverse cylinder 4; the second step is to tighten the nut 15 set on the diagonal support bolt 11 to make the lower end faces of the drainage ditch left mold 13 and the drainage ditch right mold 14 flush; the third step is to control the middle box beam 7 of the drainage ditch mold 2 and the cable trench mold 1 to descend to the design elevation by lifting the cylinder 5, and pour concrete through the gap between the baffle 16 and the cable trench right mold 9 and the gap between the drainage ditch right mold 14 and the side mold 3; the fourth step is to lift the middle box beam 7 in a small range again by lifting the cylinder 5 when the concrete is not completely solidified, and then lower it, so that the cable trench left mold 8 and the cable trench right mold 9 are flush with the lower end face of the middle box beam 7, and the mold setting can be completed.

[0022] When demoulding: the first step is to loosen the nuts 15 mounted on the diagonal support bolts 11 so that the right drain ditch template 14 has space to be lifted, and at the same time, the force between the left drain ditch template 13 and the right drain ditch template 14 can be unloaded; the second step is to lift the height of the middle box beam 7 of the drain ditch template 2 and the cable trench template 1 by the lifting cylinder 5, and the bottom of the left cable trench template 8 and the right cable trench template 9 move toward the bottom of the middle box beam 7 under the action of gravity and separate from the concrete surface, and the bottom of the left drain ditch template 13 moves toward the bottom of the right drain ditch template 14 under the action of gravity and separates from the concrete surface; the third step is to move the ditch and cable trench platform to complete the demoulding.

[0023] In order to reduce the pores inside the concrete, a vibrator 19 can be additionally provided inside the middle box beam 7. Vibration is generated by energizing the vibrator 19, so that the concrete can be compacted and the gas inside it can be discharged.

[0024] For more simple and rapid formwork setting, a fixing plate 20 for adjusting the positions of the left formwork 8 and the right formwork of the cable trench can also be additionally provided at the top of the middle box girder 7. Bolts passing through the fixing plate 20 and fixedly connected to the left formwork 8 and the right formwork 9 of the cable trench are respectively arranged at both ends of the fixing plate 20, and nuts 15 capable of abutting against the fixing plate 20 are sleeved on the bolts. By means of the fixing plate 20, it is not necessary to lift the lifting oil cylinder 5 twice during formwork setting.

[0025] In addition, in order to avoid the diagonal bracing bolts 11 from being broken, a second connecting rod 21 and a third connecting rod 22 can be additionally provided at the upper part and one side of the baffle 16 respectively. The baffle 16 is rotatably connected to the connecting columns of the right formwork 9 of the cable trench and the right formwork 14 of the drainage ditch through the second connecting rod 21 and the third connecting rod 22 respectively, so that the force is more uniform when the left formwork 8 of the drainage ditch is lifted.
