[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] Reference Figures 1 to 2The present invention provides an embodiment of a mold for pouring thick trench cover concrete, comprising a channel steel side mold 1. The steel side mold is the basic framework of the entire mold, used to support and fix other components. The cover base membrane is made of a Q235 steel plate with a thickness of 2.3mm. Its width is 2mm narrower than the net width of the trench interior, and its length is the same as that of three parallel cover plates. Angle steel 2 is detachably connected to the interior of the channel steel side mold 1. The side mold uses channel steel of appropriate height and the upper 50mm*50mm*5mm angle steel 2 uses all-thread M6. The angle steel 2 is located inside the channel steel side mold 1 and is connected to the channel steel side mold 1 by all-thread M6 bolts. The height of the angle steel 2 is moderate to accommodate concrete cover plates of varying thicknesses.

[0034] The interior of the channel steel side formwork 1 is detachably connected to two U-shaped steel plates 13. The design of the U-shaped steel plates 13 allows for disassembly and adjustment to suit different casting requirements. The interior of the angle steel 2 is provided with multiple compartments 3, which are divided into three compartments using the U-shaped steel plates 13. The compartments 3 are located inside the angle steel 2 and are divided into three independent compartments by the U-shaped steel plates 13. This design helps control the flow and distribution of concrete, ensuring uniform casting. The top of the angle steel 2 is slidably connected to a connecting rod 4, the outside of which is slidably connected to the top of the channel steel side formwork 1. The outside of the connecting rod 4 is rotatably connected to a rolling shaft 5, which is slidably connected to the top of the channel steel side formwork 1 and rotatably connected to the rolling shaft 5.

[0035] The function of the connecting rod 4 is to transmit the operator's action to the rolling shaft 5, thereby achieving rolling treatment of the concrete surface. The external rotation of the rolling shaft 5 is connected to the top of the angle steel 2. The rolling shaft 5 is connected to the top of the angle steel 2 and synchronized with the operator's action through the connecting rod 4. The surface of the rolling shaft 5 is smooth and can be rolled back and forth before the concrete begins to set, so that the concrete surface is flat. The outside of the connecting rod 4 is provided with a flattening component, which can assist the rolling shaft 5 in smoothing the concrete. The flattening component includes two connecting columns 6, and the interior of the connecting column 6 is provided with a cavity 7. The inner wall of the cavity 7 is slidably connected to the limit plate 9. When lumps appear inside during rolling, the scraper 11 will be forced to move upward.

[0036] At the same time, the two ends will squeeze the limit plate 9 toward the inside of the connecting column 6. The outer side of the limit plate 9 is fixedly connected to the connecting shaft 10, and the inner wall side of the cavity 7 is fixedly connected to the spring 8. The other end of the spring 8 is fixedly connected to the side of the limit plate 9 away from the connecting shaft 10. The outside of the limit plate 9 is slidingly connected to the inner wall of the cavity 7, and the outside of the connecting shaft 10 is slidingly connected to the right through hole of the connecting column 6. The bottom of the connecting shaft 10 is fixedly connected to the scraper 11, and the bottom of the scraper 11 is slidingly connected to the top of the angle steel 2. The spring 8 is compressed on the inner wall of the cavity 7, absorbs external force and generates a reaction force on the limit plate 9, so that the scraper 11 is reset, in close contact with the concrete surface, and presses the block into the inside to avoid affecting the finishing effect of the rolling shaft 5.

[0037] Reference Figures 3 and 4 The channel steel side form 1 has two mounting holes 12 on both the front and rear sides. The mounting holes 12 are located on the front and rear sides of the channel steel side form 1 and are used to connect the U-shaped steel plate 13 and other components. The U-shaped steel plate 13 can be accurately positioned and fixed by fixing bolts 15 and adjustable nuts 14. The U-shaped steel plate 13 is provided with a mounting assembly on the outside, which facilitates its installation with the channel steel side form 1. The mounting assembly includes a plurality of fixing bolts 15. The external threads of the fixing bolts 15 are connected to the inner wall of the mounting holes 12. The fixing bolts 15 are used to connect the U-shaped steel plate 13 to the channel steel side form 1 to ensure overall stability.

[0038] The external thread of the fixing bolt 15 is connected to the inner wall of the mounting hole 12. By rotating the nut, the distance between the top angle steel 2 and the bottom channel steel can be adjusted to control the pouring thickness of the concrete cover. The two ends of the U-shaped steel plate 13 are fixed to the side form channel steel plate using ordinary M6 bolts to ensure overall stability. The front and rear sides of the U-shaped steel plate 13 are provided with positioning holes. The front and rear sides of the U-shaped steel plate 13 are provided with positioning holes for precise positioning. The front and rear sides of the channel steel side form 1 are threaded with multiple adjustable nuts 14. The external thread of the adjustable nuts 14 is connected to the front and rear sides of the angle steel 2. The adjustable nuts 14 are used to adjust the distance between the top angle steel 2 and the bottom channel steel to control the pouring thickness of the concrete cover. The 1mm pitch bolt fixation can be fine-tuned by rotating the nut. The 1mm pitch bolt fixation can adjust the distance between the top angle steel 2 and the bottom channel steel by rotating the nut to control the pouring thickness of the concrete cover.

[0039] Working principle: First, pull the wire to locate and install the customized mold, use the adjustable nut 14 to install the U-shaped steel plate 13 inside the channel steel side mold 1, then fix it with the fixing bolt 15, return the bottom to the top for simple support, and apply the release agent. According to the requirements of the design drawing, put the tied steel bars into the template, use the jump bin method to pour concrete, use the 35# vibrator for vibration, and then drive the rolling shaft 5 to roll through the connecting rod 4, and roll back and forth to finish the surface before the concrete begins to set, until it is level with the top of the mold. When lumps appear inside during rolling, the scraper 11 will be forced to move upward, and at the same time, the two ends will squeeze the limit plate 9 toward the inside of the connecting column 6. At this time, the spring 8 is compressed on the inner wall of the cavity 7. The spring 8 will absorb external force when under pressure and generate a reaction force on the limit plate 9, so that the scraper 11 is reset, in close contact with the concrete surface, and the lumps are pressed into the inside to avoid affecting the finishing effect of the rolling shaft 5.

[0040] 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. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
