[0040] In this embodiment, the steps and principles of using the large-section rectangular box culvert splicing mold

[0041] How it works

[0042] This mold design is based on modularization and assembly principles. Through the precise connection of the fixed mold 1 and movable mold 2, and the support and movement system of the base mold 5 and slide rails 6, it enables efficient prefabrication of large-section rectangular box culverts. Specifically, the molds are positioned and secured together using connecting members 4. Concrete pouring is accomplished using the pouring port 3, while the slide rails 6 and the pulley 7 system of the base mold 5 ensure smooth movement and positioning of the movable mold 2. Furthermore, the design of the adjustment screw 12 and turntable 14 facilitates fine-tuning and stabilizes the mold, ensuring the quality of the precast part.

[0043] How to use

[0044] Assemble the bottom mold 5 and the slide rail 6: first place the bottom mold 5 on the slide rail 6, and use the pulley 7 to ensure that the bottom mold 5 can move freely along the slide rail 6.

[0045] Positioning the movable mold 2: Place the movable mold 2 on the base mold 5, ensuring that the two are tightly connected by snapping. This process may require the assistance of an external hydraulic cylinder to push the movable mold 2 onto the base mold 5 to achieve a tight fit.

[0046] Splicing the fixed and movable mold 2: Use four external hydraulic cylinders to push the movable mold 2 next to the fixed mold 1, and use positioning pins and positioning sleeves to perform preliminary positioning to ensure accurate docking between the two molds.

[0047] Fasten the mold: fasten the mold for the second time through the bolts in the connecting member 4 to ensure that the splicing parts are stable and reliable.

[0048] Pouring concrete: Concrete is poured from the pouring port 3, and at the same time, the concrete wraps around the connecting member 4, further strengthening the connection strength between the molds.

[0049] Curing and demoulding: After the concrete solidifies to a certain strength, the movable mold 2 and the bottom mold 5 are separated from the fixed mold 1 through the cooperation of the slide rail 6 and the pulley 7, thereby completing the preparation of the prefabricated parts.

[0050] Cleaning and Reuse: Clean the mold, check for damage, perform necessary maintenance, and prepare for next use.

[0051] Through the above steps, the mold can effectively produce high-quality rectangular box culvert prefabricated parts, which are suitable for the construction of various large underground passages.

[0052] like Figure 1-7 As shown, the connecting screw 13 and the adjusting screw 12 are respectively connected by a threaded connection, and the adjusting screw 12 can move up and down inside the connecting screw 13 through the thread, and the adjusting screw 12 and the connecting screw 13 are respectively welded to the internal connection position of the contact rail 11 and the support plate 8 with a turntable 14, and the adjusting screw 12 and the connecting screw 13 are respectively connected to the contact rail 11 and the support plate 8 by a sleeve connection through the turntable 14. The length of the slide rail 6 is not limited, the insert rod 10 is connected to the contact rail 11 by an integrated welding connection, and the insert rod 10 is connected to the cavity 9 by an insert connection. The movable mold 2 is connected to the bottom mold 5 by a snap-fit ​​connection. A pulley 7 is provided at the connection position of the bottom mold 5 and the slide rail 6. The movable mold 2 can move on the slide rail 6 through the pulley 7. The connecting component 4 is specifically a positioning pin, a positioning sleeve and a bolt. The movable mold 2 and the fixed mold 1 can be fixedly connected by the connecting component 4, and the pouring port 3 can be filled with cement and the connecting component 4 is wrapped.

[0053] Optionally, a plurality of slide rails 6 are provided, and the plurality of slide rails 6 are arranged in an array on the lower side of the bottom mold 5 and are horizontally aligned with the fixed mold 1 to be connected.

[0054] Preferably, after fixing the movable mold 2 on the bottom mold 5, the operator pushes the bottom mold 5 to roll using the pulley 7 through an externally installed oil cylinder, so that it contacts the slide rail 6 and travels on the slide rail 6. When the assembled movable mold 2 and the fixed mold 1 are at different levels, the height of the contact rail 11 can be adjusted by twisting the connection between the adjusting screw 12 and the connecting screw 13 on the slide rail 6, so that the adjusting screw 12 moves in the connecting screw 13. The contact rail 11 moves up and down in the cavity 9 through the insertion rod 10. After adjusting the height of the slide rail 6, the operator can open the oil cylinder again to push the movable mold 2 and the fixed mold 1 to align and fix them.

[0055] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
