Description

Technical Field

[0001] This utility model relates to the field of tunnel secondary lining concrete pouring technology, specifically an immersion pouring device for the top section of tunnel secondary lining. Background Technology

[0002] The pouring of secondary lining concrete is one of the most critical steps in tunnel construction, directly affecting the tunnel's safety and service life. Voids, cracks, honeycomb-like surfaces, and air bubbles behind the lining have long been common defects after the pouring of sand-lined concrete, posing significant challenges in tunnel construction. This is because the concrete pouring at the top of the secondary lining involves grouting through holes in the tunnel lining trolley formwork, with the concrete poured from bottom to top, thus creating these common defects.

[0003] Based on this, an immersion casting device for the top section of the tunnel secondary lining is provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0004] The purpose of this utility model is to provide an immersion-type casting device for the top section of the tunnel secondary lining, so as to solve the common defects of existing linings such as voids, top cracks, and honeycomb surface pitting after casting.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An insert-type casting device for the top section of a tunnel secondary lining includes a base, on which symmetrical fixing plates are arranged on both sides. A first track is arranged on the inner side of the fixing plates. A support plate is arranged between the fixing plates. A first fixed seat is arranged at both ends of the support plate. A first guide wheel is rotatably connected in the first fixed seat and is rolled in the first track. A lifting mechanism is arranged in the base below the support plate. A second connecting plate is arranged on both sides of the support plate. A frame is arranged on the second connecting plate. A moving mechanism is arranged in the frame. An adjustment mechanism is arranged at one end of the frame.

[0007] Based on the above technical solutions, this utility model also provides the following optional technical solutions:

[0008] In one alternative: the lifting mechanism includes a load-bearing plate located inside the base, a first lifting cylinder is provided on the load-bearing plate, a first connecting plate is provided between the support plates, and the output end of the first lifting cylinder is fixedly connected to the first connecting plate.

[0009] In one alternative: the moving mechanism includes a second track located on the inner walls of both sides of the frame, a moving plate is provided inside the frame, and second fixed seats are provided on both sides of the moving plate. Second guide wheels are rotatably connected to the second fixed seats and are rolled within the second track. A casting box is provided on the moving plate.

[0010] In one alternative: a mounting plate is provided at one end of the frame, and a reinforcing rib is provided between the bottom of the mounting plate and the side wall of the frame.

[0011] In one alternative: the adjusting mechanism includes a second lifting cylinder, which is located on the mounting plate. A fixing ring is provided on the outside of the second lifting cylinder, and the fixing ring is fixedly connected to the mounting plate by screws. The output end of the second lifting cylinder is fixedly connected to the casting box.

[0012] In one alternative: a pouring pipe is provided on one side of the pouring box, and the pouring pipe is fixedly connected to the pouring box by a pipe delivery chuck.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This utility model uses a lifting mechanism to move the support plate up and down to adjust the height. The adjustment mechanism can also drive the moving mechanism to adjust the distance laterally. The concrete is poured by inserting the pouring pipe into the top section of the tunnel lining, avoiding the problem of pouring concrete from bottom to top, which can lead to defects such as voids, cracks, honeycomb surface, and bubbles behind the lining.
