[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model. In the accompanying drawings, the dimensions and relative dimensions of certain parts may be enlarged for clarity.

They are only for the convenience of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0026] Furthermore, in the description of this utility model, the terms "first" and "second" are used merely for descriptive distinction and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Additionally, features defined with "first" and "second" may explicitly or implicitly include one or more of that feature.

[0027] As per the instruction manual Figure 1 and 2 As shown, this utility model provides a rainwater box culvert formwork system, including a support body 4 and two sets of side formwork units 2. The two sets of side formwork units 2 are respectively arranged on both sides of the support body 4. Each side formwork unit 2 includes two side templates 21 and several tie rods 22 connecting the two side templates 21. The two side templates 21 are spaced apart and the distance between them is the same as the thickness of the side wall to be poured. The bottom of the support body 4 is provided with a walking mechanism 5, and the top of the support body 4 is provided with a cantilever beam 6. The two sets of side formwork units 2 are respectively arranged at both ends of the cantilever beam 6, and the two side templates 21 of the same set of side formwork units 2 are respectively connected to the cantilever beam 6 through a lifting mechanism 7.

[0028] Specifically, in this embodiment, the longitudinal direction refers to the length of the rainwater culvert. When pouring the side walls, the side formwork is laid out longitudinally. The transverse direction is perpendicular to the longitudinal direction, that is, the transverse direction is perpendicular to the surface of the side formwork. The vertical direction refers to the vertical direction. During construction, the culvert bottom slab is poured first to form the pre-cast culvert bottom slab 1. Then, the support body 4 is set on the pre-cast culvert bottom slab 1 and the side formwork is assembled to pour the culvert side walls. After the side walls are poured, the culvert top slab 3 is constructed at the top of the side walls. The culvert top slab 3 can be a cast-in-place culvert top slab or a precast culvert top slab. In this embodiment, a precast culvert top slab is used. When pouring the culvert side slab, anchor bolts 8 are pre-embedded. After the culvert side walls are poured, the precast culvert top slab is connected to the anchor bolts 8, thus completing the rainwater culvert construction, as shown in the appendix to the instruction manual. Figure 5 As shown.

[0029] Preferably, due to the long length of the stormwater culvert, it is divided into multiple culvert segments for construction, which facilitates construction and improves construction efficiency. The pouring length of the culvert bottom slab segment is strictly set according to the design requirements or the length of the expansion joint. Multiple culvert bottom slab segments can be poured at one time. After the pouring of one culvert bottom slab is completed, multiple support bodies 4 can be set longitudinally on the previously poured culvert bottom slab 1 until it is extended to the length of the previously poured culvert bottom slab segment. The length of the side formwork 21 is equal to the length of the culvert segment, and expansion joints are provided between longitudinally adjacent culvert sidewalls.

[0030] In the optimized implementation, the position of each lifting mechanism on the cantilever beam is adjustable, and the adjustment direction is parallel to the transverse direction, which is perpendicular to the surface of the side formwork. By adjusting the position of the lifting mechanism on the cantilever beam, the spacing between the two side formworks of the same side formwork unit can be adjusted. On the one hand, this facilitates demolding, and on the other hand, it avoids the side formwork from impacting the culvert sidewall during the movement of the support body. On the other hand, it can meet the construction requirements of sidewalls of different thicknesses to be poured, making it highly adaptable. The side formwork moves up and down under the action of the lifting mechanism and can also move laterally, which can meet the construction requirements of different culvert sidewalls and accommodate side formwork processing errors, improving the uniformity of rainwater culvert sidewall pouring and enhancing the quality of rainwater culvert pouring.

[0031] In an optimized implementation, the number of cantilever beams 6 is at least two. Each cantilever beam 6 is longitudinally spaced on the support body 4. The number of lifting mechanisms 7 connected to each side template 21 is the same as the number of cantilever beams 6, and they are connected one-to-one with each cantilever beam 6. In this embodiment, two cantilever beams 6 are provided, respectively located at both ends of the support body 4 along the longitudinal direction. Each side template 21 is equipped with two corresponding lifting mechanisms 7 connected to the corresponding cantilever beam 6. The two lifting mechanisms 7 are respectively connected to both ends of the side template 21. The lifting mechanisms 7 can adjust the height of the side template 21. The two lifting mechanisms 7 of the same side template 21 can be adjusted independently. The height of the side template 21 can be adjusted as needed to accommodate the construction error of the first-cast box culvert bottom slab 1, thereby improving the casting accuracy and quality of the box culvert sidewalls.

[0032] In an optimized implementation, the lifting mechanism 7 includes an adjustable hoist 72, which is mounted on the cantilever beam 6 via a lifting lug 71. The side template 21 is suspended from the output end of the adjustable hoist 72. The cantilever beam 6 is provided with a lifting lug 71, and the adjustable hoist 72 is suspended from the lifting lug 71. The output end of the adjustable hoist 72 is connected to the side template 21, and the adjustable hoist 72 is provided with a manual pull end, through which the installation height of the side template 21 can be adjusted.

[0033] As one specific implementation method, the position of the lifting lug 71 on the cantilever beam 6 is adjustable and the adjustment direction is parallel to the transverse direction. The cantilever beam 6 is provided with multiple mounting holes spaced apart along the transverse direction. The lifting lug 71 is selectively installed on one mounting hole by bolts, so that the installation position of the lifting lug 71 can be adjusted in the transverse direction to adjust the position of the side formwork 21 in the transverse direction and the distance between the two side formworks 21, so as to correct the offset caused by the movement of the support body 4, or to meet the different requirements for the pouring of the box culvert sidewall thickness.

[0034] As one specific implementation, the position of the lifting lug 71 on the cantilever beam 6 is adjustable and the adjustment direction is parallel to the lateral direction. The cantilever beam 6 is provided with a slide rail, and the lifting lug 71 is provided with a slider that can move along the slide rail. The lateral position of the side template 21 and the distance between the two side templates 21 can be adjusted by moving the lifting lug 71.

[0035] In an optimized implementation, both ends of the cantilever beam 6 extend to the outer side of the support body 4 to form cantilever ends. Two side formwork units 2 are provided, located on opposite sides of the support body 4 and connected to the corresponding cantilever ends. In use, both ends of the cantilever beam 6 are equipped with side formwork units 2. The support body 4 is moved to the target position, and then the two side formworks 21 of each side formwork unit 2 are connected by tie rods 22, allowing simultaneous pouring of the two side walls of the rainwater culvert.

[0036] Specifically, see the instruction manual. Figure 1 As shown, the bottom of the side formwork 21 is located below the side wall of the first-cast box culvert bottom slab 1. The two side formworks 21 are respectively set on both sides of the side wall of the first-cast box culvert bottom slab 1. The bottom of the side formwork 21 is attached to the side wall of the first-cast box culvert bottom slab 1, and the bottom of the two side formworks 21 is connected to the side wall of the first-cast box culvert bottom slab 1 by tie rod 22.

[0037] Optimized implementation methods, as shown in the appendix to the instruction manual. Figure 3 and 4The diagram shows the structure of the side formwork 21. Each side formwork 21 includes a formwork frame and a panel 213. The panel 213 is disposed on the side of the formwork frame facing the side wall to be poured. The lifting mechanism 7 is connected to the formwork frame. The formwork frame is configured with multiple longitudinal back ribs 211 parallel to the length direction of the panel and multiple vertical back ribs 212 parallel to the vertical direction. The length direction of the longitudinal back ribs 211 is parallel to the longitudinal direction. The multiple longitudinal back ribs 211 are arranged at intervals along the vertical direction. The vertical back ribs 212 are parallel to the vertical direction. The multiple vertical back ribs 212 are welded to the longitudinal back ribs 211 at intervals along the longitudinal direction. The multiple longitudinal back ribs 211 and the multiple vertical back ribs 212 are welded to form the formwork frame. The template frame has a panel 213 on the side facing the side wall pouring area, and a vertical rib 214 on the side away from the side wall pouring area. The top of the vertical rib 214 extends to the outside of the template frame and the extended end has a hoisting hole 215. The adjusting hoist is connected to the hoisting hole 215.

[0038] In an optimized implementation, the panel 213 is an aluminum alloy panel.

[0039] In the optimized implementation, the longitudinal back rib 211, the vertical back rib 212, and the vertical large rib 214 are all made of channel steel.

[0040] In an optimized implementation, a limiter 61 is provided at the end of the cantilever beam 6 away from the support body 4 to prevent the lug 71 from falling out of the cantilever beam 6.

[0041] In an optimized implementation, the support body 4 includes multiple sets of vertical rods arranged at intervals along the transverse direction. Each set of vertical rods includes multiple vertical rods 41 arranged at intervals along the longitudinal direction. The multiple vertical rods 41 in the same set are connected by longitudinal rods, and the multiple vertical rods 41 in the same transverse direction are connected by transverse rods 42. The cantilever beam 6 is disposed on the vertical rods 41, and the traveling mechanism 5 is disposed at the bottom of the vertical rods. The length direction of the vertical rods is parallel to the vertical direction, the length direction of the transverse rods is parallel to the transverse direction, and the length direction of the longitudinal rods is parallel to the longitudinal direction.

[0042] Specifically, the longitudinal members include two lower support beams 43, which are arranged horizontally. There are four vertical members 41, each mounted in pairs on one of the lower support beams 43. Two vertical members 41 on the same lower support beam 43 are positioned at opposite ends of the beam. Two cantilever beams 6 are positioned on the two front vertical members 41 and the two rear vertical members 41, respectively. A crossbar 42 is provided between two adjacent horizontally arranged vertical members 41. To improve the strength of the support body 4, a star-shaped support beam 44 is provided between two adjacent horizontally arranged vertical members 41.
