[0002] A box culvert refers to a culvert whose tunnel body is constructed with reinforced concrete box-shaped pipe sections. A box culvert is usually composed of a top plate and side walls spliced ​​together into a cubic shape.

[0003] Box culvert production usually adopts mold forming technology, which uses several templates to splice to form a mold, then arranges steel mesh in the mold cavity and pours concrete. After the concrete hardens, the mold is removed to obtain the box culvert component.

[0004] When pouring the side wall, concrete often splashes out of the side wall mold cavity and into the top plate mold cavity. The splashed concrete droplets adhere to the inner wall of the top plate mold cavity and harden and solidify. They cannot form a whole with the concrete injected during the subsequent box culvert top plate pouring, resulting in defects such as spots and bubbles on the box culvert top plate components.

[0039] Reference Figures 1 to 4 This embodiment provides a concrete pouring tool for a box culvert sidewall, comprising a hopper 1, a delivery pipe 2, and a clamping module 3. The hopper 1 receives a flow of concrete slurry; the delivery pipe 2 serves as a pouring channel, extending the pouring outlet downward to a position away from the top plate mold; and the clamping module 3 securely mounts the hopper 1 to the formwork 51 of the sidewall mold 5 while fitting a steel mesh 6.

[0040] Reference Figures 1 and 2 Hopper 1 is shaped like an inverted quadrangular pyramid, with feed pipe 2 positioned vertically at the center of the bottom plate of hopper 1. The inner cavity of feed pipe 2 communicates with the inner cavity of hopper 1. During pouring, concrete flows through hopper 1 and feed pipe 2 in sequence, entering the middle and lower part of the cavity of side wall mold 5, thereby staying as far away from the cavity of the top plate mold as possible.

[0041] Reference Figures 1 to 4 A laterally extending snap-in rib 11 is provided at the bottom edge of the side wall of the hopper 1. The snap-in rib 11 is provided with two first and second ribs 111, 112. The first and second ribs 111, 112 are arranged in an L-shape; the first and second ribs 111, 112 are both fixedly connected to the bottom plate of the hopper 1 in an integrated manner.

[0042] Reference Figure 4 and Figure 5 The snap-on module 3 includes a magnetic box 31, a screw assembly 32, a reinforcing rib 33, and an engaging claw 34. The magnetic box 31 and the screw assembly 32 are fixedly connected in an L-shape (e.g., by bolts). The reinforcing rib 33 is fixedly disposed at the connection between the magnetic box 31 and the screw assembly 32. The reinforcing rib 33 is a plate-like structure in the shape of a right triangle. One right-angled edge of the reinforcing rib 33 is welded to the housing 321 of the screw assembly 32, and the other right-angled edge is welded to the outer shell of the screw assembly 32.

[0043] Reference Figure 4 and Figure 5 The screw assembly 32 is connected to the engaging claw 34 and can drive the engaging claw 34 to move laterally, so that the engaging claw 34 can bite / loosen the first convex rib 111 / the second convex rib 112, thereby fixing the hopper 1 and the feed pipe 2 on the side wall of the template 51, preventing the hopper 1 and the feed pipe 2 from tilting, shaking, or rotating, thereby ensuring stability.

[0044] Reference Figures 4 to 6 The engaging claw 34 is provided with an engaging groove 341 adapted to the cross section of the snap-fitting rib 11 , and the opening direction of the engaging groove 341 points to the hopper 1 .

[0045] Reference Figure 6The screw assembly 32 includes a housing 321, a screw 322, a slider 323 and a bearing 324; the housing 321 is provided with a sliding cavity 3211 and a sliding groove 3212 connected to the sliding cavity 3211; the screw 322 is rotatably arranged in the sliding cavity 3211 through the bearing 324, the slider 323 is sleeved on the surface of the screw 322 and is connected by threads, and the end of the engaging claw 34 is placed in the sliding groove 3212 and fixedly connected to the slider 323.

[0046] Reference Figure 6 Two bearings 324 are provided and are respectively installed at both ends of the sliding groove 3212 by bolts, thereby improving the rotation stability of the screw rod 322.

[0047] Reference Figure 6 A mounting hole is provided on the side wall of the shell 321 away from the magnetic box 31, and one end of the screw rod 322 away from the magnetic box 31 is inserted into the mounting hole; the one end of the screw rod 322 away from the magnetic box 31 is fixedly connected to a gripping wing 325 (for example, through an integrated fixed connection or a fixed connection through welding).

[0048] Reference Figure 6 The gripping wing 325 is placed outside the sliding cavity 3211 , so that the user can grab the gripping wing 325 to further rotate the screw 322 .

[0049] Reference Figure 6 and Figure 7 , a clamping rod 12 is provided at the top of the outer wall of the hopper 1, and the clamping rod 12 is fixedly connected to the outer wall of the hopper 1 by bolts or by an integrated fixed connection. A clamping cavity is provided at a position of the side wall of the clamping rod 12 away from the hopper 1, and the cross-section of the clamping cavity is convex; the utility model also includes a shielding film 4, which includes a clamping strip 41 and a plastic film 42 fixedly connected to each other (for example, by hot-melt connection); the cross-section of the clamping strip 41 is convex and fits the clamping cavity. When pouring concrete, the user inserts the clamping strip 41 into the clamping cavity, and then covers the plastic film 42 on the clamping module 3 to prevent splashing concrete droplets during pouring from flowing into the sliding cavity 3211 and the sliding groove 3212, further protecting the screw rod 322.

[0050] Reference Figure 7 The clamping rod 12 is tilted, so that the clamping cavity is tilted to prevent splashing / overflowing concrete from flowing into the clamping cavity.

[0051] Reference Figure 5 and Figure 7 The clamping rod 12 is placed above the clamping rib 11; there are two clamping rods 12, which are respectively installed above the first rib 111 and the second rib 112. There are two shielding films 4, which are respectively adapted to be installed with the two clamping rods 12.

[0052] The delivery pipe 2 is in the shape of a straight cylinder; the delivery pipe 2 is vertically fixedly connected to the bottom plate of the hopper 1, so that the concrete flow in the delivery pipe 2 has good fluidity.

[0053] Reference Figure 6 The gripping wing 325 is a C-shaped plate structure, which is convenient for users to grip.

[0054] Reference Figure 2 and Figure 8 The snap-in modules 3 are provided with two and can be snap-engaged with the first convex rib 111 and the second convex rib 112 respectively.

[0055] Reference Figure 2 、 Figure 3 and Figure 8 When it is necessary to cast the vertical joint position of the two templates 51, the two clamping ribs 11 are respectively set parallel to the two templates 51, and then the two clamping modules 3 are used to engage and lock the hopper 1 and the two templates 51 (the side of the conveying pipe 2 close to the clamping module 3 abuts against the inner wall of the template 51; the side of the conveying pipe 2 away from the clamping module 3 abuts against the intersection of the steel bars in the steel mesh 6).

[0056] Reference Figure 9 When it is necessary to cast the middle part of the template 51, any one of the clamping ribs 11 is set parallel to the template 51 (the clamping rib 11 is located on the outside of the template 51), and then a single clamping module 3 is used to engage and lock the hopper 1 and the template 51 (the side of the conveying pipe 2 close to the clamping module 3 abuts against the inner wall of the template 51; the side of the conveying pipe 2 away from the clamping module 3 abuts against the steel mesh 6).

[0057] Reference Figure 10 When the width of the gap between the steel mesh 6 and the template 51 is greater than the diameter of the feed pipe 2, the hopper 1 and the feed pipe 2 are tilted toward the steel mesh 6, thereby ensuring that the side of the feed pipe 2 close to the clamping module 3 abuts against the inner wall of the template 51, and the side of the feed pipe 2 away from the clamping module 3 abuts against the steel mesh 6, thereby ensuring the stability of the connection, preventing the hopper 1 and the feed pipe 2 from shaking and rotating during concrete pouring, and further preventing concrete from splashing and scattering.

[0058] Reference Figure 6 A rubber layer 342 is fixedly installed on the inner wall of the bite groove 341 (for example, fixedly connected by bolts or fixedly connected by snapping), thereby increasing the snapping compatibility of the bite groove 341 with the inclined or horizontally arranged snapping rib 11.

[0059] Usage steps: ① Install the hopper 1 and the feed pipe 2 at the position of the side wall mold 5, so that the bottom plate of the hopper 1 is pressed against the top surface of the steel mesh 6 / the top surface of the template 51, and the feed pipe 2 is inserted into the gap between the edge of the steel mesh 6 and the inner wall of the template 51; ② Install the clamping module 3 on the outer wall of the template 51, so that the magnetic box 31 only attracts the steel template 51; ③ Rotate the gripping wing 325 to move the engaging claw 34 toward the direction of the hopper 1 until the engaging rib 11 and the engaging groove 341 are clamped with each other; ④ Use the pipeline to pour concrete into the hopper 1 to carry out the pouring operation.
