Technical Field

[0001] The present application belongs to the field of tunnel engineering, and more specifically, relates to a device for controlling the cross slope forming of an inverted arch filling surface. Background Art

[0002] Tunnel structures typically consist of an arch ring, sidewalls, inverts, invert filling, advanced support systems, and mechanical, electrical, ventilation, and lighting systems. The invert filling is a critical component of tunnel structures, and its quality directly impacts tunnel operational safety. Most invert fillings are constructed using the cast-in-place method, and the quality control requirements for invert filling are becoming increasingly stringent during tunnel construction.

[0003] The traditional method for tunnel invert filling construction involves measuring and laying out the invert filling end formwork, side formwork, and center ditch formwork, and marking them with an ink fountain. Workers then slope the filling surface according to the marked lines. However, this construction method places high demands on the workers' construction skills, and the flatness often cannot be well controlled during the construction process, resulting in inconsistent cross slopes, which in turn affects the overall quality of the tunnel. Summary of the Invention

[0014] By adopting the above technical solution, the height position can be adjusted on the screw rod by rotating the nut, and the nut supports the bottom of the connecting plate, so that the position of the connecting plate can be adjusted, thereby adjusting the height of the sink mold.

[0015] As a further preferred embodiment, a limiting cylinder is vertically fixedly connected to the fixing frame, a limiting rod is fixedly connected to the connecting plate, and the limiting rod is inserted into the limiting cylinder.

[0016] By adopting the above technical solution, when the connecting plate drives the water tank mold to rise, the limiting rod is located inside the limiting cylinder to limit the angle of the connecting plate, making the connecting plate and the water tank mold more stable when rising.

In actual construction, a total station is used to lay out the side line of the inverted arch filling 13, and the filling side form 1 is erected according to the lofting result. After the filling side form 1 is erected and reinforced, double-sided tape is used to stick elevation lines at the top surfaces of the templates around it, and the lower edge of the double-sided tape is the elevation of the top surface of the filling surface; after the filling side form 1 is reinforced, the trough form 2 is installed and fixed to the filling side form 1, and the elevation is adjusted so that the top surface of the trough form 2 is consistent with the design elevation, so that after the inverted arch filling 13 is formed, a drainage trough is formed at the trough form 2, and the upper surface of the trough form 2 is a horizontal plane. In this embodiment, the cross-section of the trough form 2 is semicircular.

[0036] The water tank mold 2 is set on one side of the filling side mold 1. The water tank mold 2 is parallel to the setting direction of the filling side mold 1, and one side of the water tank mold 2 is in contact with the filling side mold 1. Specifically, the fixing frame 5 is installed on the side of the filling side mold 1 away from the inverted arch filling 13. The screw rod 6 is vertically fixedly connected to the fixing frame 5. The nut 7 is sleeved on the screw rod 6 and threadedly connected. The screw rod 6 passes through the connecting plate 8 and the nut 7 abuts against the bottom of the connecting plate 8. The nut 7 supports the bottom of the connecting plate 8. Turn the nut 7 to adjust its The position on the screw rod 6 can adjust the height of the connecting plate 8. The water tank mold 2 is fixedly connected to one end of the connecting plate 8 and is located on the side of the filling side mold 1 close to the arch filling 13, thereby adjusting the height of the water tank mold 2. To ensure the stability of the connecting plate 8 during lifting and lowering, the fixing frame 5 is vertically fixedly connected to the limiting cylinder 9, and the connecting plate 8 is fixedly connected to the limiting rod 10. The limiting rod 10 is inserted into the limiting cylinder 9. The angle of the connecting plate 8 is limited by the limiting rod 10, so that it can move stably in the vertical direction.

[0037] The transverse slope forming component 3 is horizontally arranged on the side of the water tank mold 2 away from the filling side mold 1. The transverse slope forming component 3 is used to form a certain slope for the arch filling 13. The transverse slope forming component 3 includes a horizontal plate 301 and a forming plate 302. In this embodiment, the forming plate 302 and the horizontal plate 301 are an integrated forming structure. The forming plate 302 is arranged at the bottom of the horizontal plate 301. After the filling concrete is poured and before the initial setting, one end of the horizontal plate 301 is placed on the top of the water tank mold 2. The horizontal plate 301 is placed horizontally, and the spirit level 4 is fixedly installed on the horizontal plate 301. The spirit level 4 is perpendicular to the water tank mold 2. One end of the forming plate 302 is in contact with the water tank mold 2. The square steel 12 is fixed with steel bars at a distance of 1.05m from the outside of the filling side mold 1. It is placed on the surface of the inverted arch filling 13 and on the side of the horizontal plate 301 away from the trough mold 2. The horizontal plate 301 is in contact with the square steel 12, and the position of the horizontal plate 301 is fixed by the square steel 12. The bottom of the forming plate 302 is an inclined surface, and the lower end of the inclined surface is close to the side of the trough mold 2, so that the surface of the inverted arch filling 13 forms an inclined structure close to the trough mold 2. The horizontal slope of the surface of the formed inverted arch filling 13 forms a certain slope, and the slope is the same as the inclined surface at the bottom of the forming plate 302. The slope control of the inverted arch filling 13 is precise, and the slope surface is smoother.
