In the construction of a double-layer tunnel / cave, when concrete needs to be poured for both the upper and lower layers, the conventional method is to first pour the first layer, and when the first layer reaches sufficient strength, then start pouring the second layer so that the secondary lining can be poured on the second layer.

[0021] As Figure 1 shown, an integral concrete pouring trolley for the upper and lower layers and the overlapping section of the middle plate includes two lower bottom beams 1 at the bottom. A lower steel frame 2 is installed on the lower bottom beam 1. A support device is installed on the lower bottom beam 1 at the rear of the lower steel frame 2. On the upper part of the support device, an upper steel frame 3 is connected to the same side of the lower steel frame 2, and the upper steel frame 3 extends forward out of the lower steel frame 2. Except as specifically described in the present invention, the lower steel frame 2 and the upper steel frame 3 are both conventional trolley steel frames. Through the foregoing design, with the start and rearward movement of the trolley, the simultaneous construction of the concrete works for the upper and lower tunnels / tunnels and the overlapping section of the middle plate can be realized, and the pouring can be completed at one time.

[0022] As Figure 2 shown, upper bottom beams 301 are provided at both bottom sides of the upper steel frame 3. A connecting plate 302 is commonly connected to the lower parts of the two upper bottom beams 301. The connecting plate 302 is located between the two upper bottom beams 301, that is, between the lower parts of the two upper bottom beams 301. An installation seat 303 is installed on each side below the connecting plate 302. A pressing oil cylinder 304 is connected to the lower end of each installation seat 303, and the end of the piston rod of the pressing oil cylinder 304 is connected to a leveling formwork 309. By using the present application, the upper tunnel, the lower tunnel, and the overlapping section of the middle plate 6 between the two layers of tunnels are poured simultaneously, and the leveling formwork 309 can level the upper part of the overlapping section of the middle plate 6.

[0023] In this embodiment, the connection and installation method of the installation seat 303 and the connecting plate 302 is as follows: a transverse slide rail (not shown) is provided below the connecting plate 302, and the two installation seats 303 are connected to the slide rail through sliders (not shown), and the sliders are connected to the piston rod of the translation oil cylinder 305. Through the movement of the piston rod of the translation oil cylinder 305, the synchronous left and right movement of the pressing oil cylinder 304 and the leveling formwork 309 can be realized.

[0024] In this embodiment, a first motor 306 is installed on the connecting plate 302. The output shaft of the first motor 306 is connected to a first speed reducer 307. The output shaft of the first speed reducer 307 is connected to a power shaft 308. The connection method between the first speed reducer 307 and the power shaft 308 can be connected through a coupling, or can be linked through a belt pulley or a sprocket. As Figure 3As shown in the figure, a traveling wheel 4 is connected to the power shaft 308, and the traveling wheel 4 is installed on the guide rail 319 of the upper bottom beam 301. Through the above design, the connecting plate 302 can move back and forth along the length direction of the upper bottom beam 301. Therefore, generally speaking, in this embodiment, the connecting plate 302 can drive the downward pressing oil cylinder 304 and the leveling formwork 309 to move freely back and forth and left and right. At the same time, due to the movement of the downward pressing oil cylinder 304 itself, the leveling formwork 309 can also move up and down, so as to realize the precise control of the position where the leveling formwork 309 is located.

[0025] Top beams 310 are supported and connected above both upper bottom beams 301. An upper cross beam 311 is installed on the two top beams 310. Upward upper jacking oil cylinders 312 are installed on both sides of the upper part of the upper cross beam 311. The piston rods of the upper jacking oil cylinders 312 support and connect an upper formwork 313 upward, so that concrete can be poured on the top of the upper tunnel.

[0026] A downward running oil cylinder 419 with a piston rod downward is connected to the lower end of the upper bottom beam 301. A reserved hole for the downward running oil cylinder 419 to pass through is provided on the leveling formwork 309. The piston rod of the downward running oil cylinder 419 can run to the top of the gantry 314 on the lower steel frame 2. During pouring, the downward running oil cylinder 419 can pass through the leveling formwork 309, transmit the weight of the upper end force such as the weight of the upper formwork 313 and the weight of the upper end concrete to the lower trolley, and then to the ground, thereby enhancing the overall stability of the present invention and enabling the smooth completion of the pouring of the double-layer tunnel.

[0027] In this embodiment, the support device includes two main support columns 101 respectively located on the two lower bottom beams 1. At least one inclined support column 102 is connected between the main support column 101 and the lower bottom beam 1. The inclined support column 102 and the lower steel frame 2 are respectively located on the front and rear sides of the main support column 101. On one side of the inclined support column 102, a connecting bracket 103 connected to the main support column 101 is provided on the lower bottom beam 1. An inclined support rib 104 connected to the upper steel frame 3 is also provided on the main support column 101. In addition, a counterweight 105 is provided at the end of the lower bottom beam 1 opposite to the lower steel frame 2. The support device in this application can play a very good translational support role in the overall operation of the trolley, so that the trolley can maintain good balance and stability during pouring and traveling.

[0028] A trolley traveling mechanism 5 is connected to the lower end of the lower bottom beam 1. In this application, connecting the traveling mechanism to the lower end of the lower bottom beam 1 can enable the whole application to travel on the track, which is convenient for construction. In this embodiment, as Figure 4 shown, the trolley traveling mechanism 5 includes bottom traveling wheels 501 installed at the front and rear of the lower bottom beam 1. The axle of the bottom traveling wheel 501 at the rearmost part (the rear part in the attached drawing, the front end during actual traveling) is connected to the belt pulley or sprocket of the power mechanism. The power mechanism includes a second motor 503 and a second speed reducer 504 that cooperate with it.

[0029] When the present invention works, driven by the second motor 503, the whole of the present invention moves forward to the rear in the figure so as to simultaneously perform concrete pouring on the upper and lower layers of the double-layer tunnel and the middle plate 6 of the overlapping section. The specific pouring process is as follows: Before pouring, the leveling formwork 309 moves forward to the front in the figure driven by the connecting plate 302, and workers start to tie the steel bars of the middle plate 6 of the overlapping section. After completion, the leveling formwork 309 moves to the rear in the figure driven by the connecting plate 302 and reaches the upper part of the lower steel frame 2. The downward cylinder 419 moves, and its piston rod passes through the leveling formwork 309 and supports on the top of the portal frame 314 on the lower steel frame 2, transmitting the upper force to the ground through the downward cylinder 419 and the lower steel frame 2, so that the whole of the present application reaches a stable state, and then concrete pouring is carried out. In this state, the upper tunnel, the lower tunnel and the middle plate 6 of the overlapping section can be poured simultaneously, which not only improves the efficiency of concrete pouring, but also greatly improves the strength of the tunnel, especially the middle plate 6 of the overlapping section, because the upper and lower tunnels and the middle plate 6 of the overlapping section are poured at one time, making the overall life and durability of the tunnel longer and improving the quality of tunnel construction.

It should be understood that those of ordinary skill in the art can make many modifications and variations based on the concept of the present invention without creative work.
