[0025] Embodiment one: a mine method connecting channel construction safety reinforcing structure, comprising a mountain body 1, a first tunnel 2 and a second tunnel 3 are arranged on the mountain body 1 respectively, a connecting channel 4 is arranged between the first tunnel 2 and the second tunnel 3, a top wall reinforcing plate 5 is arranged at the top of the connecting channel 4, a plurality of reinforcing support assemblies 6 are arranged at the bottom end of the top wall reinforcing plate 5, and the plurality of reinforcing support assemblies 6 are arranged in a cross manner at the side edges of the bottom end of the top wall reinforcing plate 5.

[0026] The reinforcing support assembly 6 comprises a reinforcing support plate 601 arranged in a fit manner in the inner wall of the connecting channel 4, a mounting insertion hole 602 is formed at the bottom end of the reinforcing support plate 601, a fixing screw 603 is inserted into the mounting insertion hole 602, a top insertion slot 604 is formed at the top end of the reinforcing support plate 601, an adjusting insertion plate 605 is slidably inserted into the top insertion slot 604, two fastening screw holes 606 are symmetrically formed at the two sides of the top end of the reinforcing support plate 601, a fastening screw 607 is inserted into each of the fastening screw holes 606, a top connecting frame 608 is arranged at the top end of the adjusting insertion plate 605, a reinforcing support rod 609 is arranged at the top side of the adjusting insertion plate 605, a first connecting block 610 is arranged at the end of the reinforcing support rod 609, and a first insertion hole 611 is formed in the middle of the first connecting block 610.

[0027] The first connecting block 610 is inserted into the top connecting frame 608, a second insertion hole 612 is symmetrically formed at the two sides of the top connecting frame 608, a connecting screw 613 is inserted into the second insertion hole 612, the end of the connecting screw 613 penetrates the second insertion hole 612 and the first insertion hole 611 in sequence, a connecting nut 614 is sleeved on the end of the connecting screw 613, a second connecting block 615 is arranged at the other end of the reinforcing support rod 609, a fixed connecting frame 616 is arranged at the end of the reinforcing support rod 609, the second connecting block 615 and the fixed connecting frame 616 are rotationally connected through a rotating connecting column 617 arranged therebetween, and the fixed connecting frame 616 is fixedly connected with the bottom side edge of the top wall reinforcing plate 5.

[0028] Embodiment two: the difference between this embodiment and embodiment one is that the bottom end of the reinforcing support plate 601 is in an L-shaped bent shape.

[0029] The contact area of the bottom of the reinforcing support plate 601 with the bottom of the connecting channel 4 is effectively increased.

[0030] Embodiment three: the difference between this embodiment and embodiment one is that the bottom end of the fixing screw 603 is in a pyramid shape, and the fixing screw 603 is inserted into the bottom of the connecting channel 4 through the mounting insertion hole 602.

[0031] The connection of the reinforcing support plate 601 with the bottom of the connecting channel 4 is more convenient.

[0032] The fourth embodiment is different from the first embodiment in that the reinforcing support rod 609 and the bottom wall of the top wall reinforcing plate 5 and the side wall of the connecting passage 4 form a triangular support structure.

[0033] The reinforcing support rod 609 is supported by the adjusting insert plate 605, and the triangular support structure is more stable, thereby providing reinforcement and protection for the top wall of the connecting passage 4.

[0034] In the present embodiment, due to the existing connecting tunnel vault reinforcing structure, the top plate is usually matched with the support rod to resist and fix. This reinforcing method requires more support rods, which greatly occupies the internal space of the connecting passage, thereby being inconvenient for subsequent operation of the construction workers, and has great limitations in use.

[0035] In summary, after the workers excavate the connecting passage 4 to connect the first tunnel 2 and the second tunnel 3, in order to make the subsequent operation more secure, the top wall reinforcing plate 5 and the reinforcing support assembly 6 are arranged in the connecting passage 4, the top wall reinforcing plate 5 is attached to the top wall of the connecting passage 4, the reinforcing support rod 609 in the reinforcing support assembly 6 is connected to the bottom end of the top wall reinforcing plate 5 through the fixed connection frame 616 arranged at the end thereof, the end of the reinforcing support rod 609 is rotatably connected to the fixed connection frame 616 through the second connecting block 615 and the rotating connection column 617, the other end of the reinforcing support rod 609 is inserted into the top connection frame 608 through the first connecting block 610 arranged at the other end, the first connecting block 610 and the top connection frame 608 are sequentially penetrated by the connecting screw 613 inserted between the second insertion hole 612 and the first insertion hole 611, and the end of the connecting screw 613 is sleeved with the connecting nut 614, thereby enabling the end of the reinforcing support rod 609 to be rotatably fixed to the top end of the adjusting insert plate 605.

[0036] And the adjusting plug-in plate 605 is inserted in the top slot 604 opened at the top end of the reinforcing support plate 601, so that the user can adjust the height of the adjusting plug-in plate 605, so that when the reinforcing support rod 609 is supported at the bottom, the end of the reinforcing support rod 609 can provide support height for the communication passage 4 of different height, which expands the application range of the device and is convenient for the flexible use of the user. The reinforcing support rod 609, the bottom side of the top wall reinforcing plate 5 and the side wall of the communication passage 4 can form a triangular support structure, so that the bottom of the top wall reinforcing plate 5 is more stable. The top wall of the communication passage 4 is stably supported by the top wall reinforcing plate 5, which plays a reinforcing role on the top of the communication passage 4. Since the reinforcing support rod 609 is arranged at the top side of the communication passage 4, the reinforcing support plate 601 supported by the end of the reinforcing support rod 609 can be arranged on the side wall of the communication passage 4, so that this kind of support reinforcing mode will not occupy too much space in the communication passage 4, which is beneficial for the construction personnel to go back and forth between the first tunnel 2 and the second tunnel 3 through the communication passage 4, and is more in line with the use requirement of the user.
