Technical Field
[0001] This utility model relates to the field of blasting construction technology, and specifically to a blasting construction structure. Background Technology
[0002] During blasting operations, it is necessary to drill blasting holes and place explosive charges in the pre-blasting area. For smooth tunnel blasting, it is necessary to drill a large number of peripheral holes, auxiliary holes, and cut holes, and install explosive charges in the blasting holes. Due to the height of the tunnel, it is difficult for construction personnel to carry out drilling and install explosive charges while standing on the ground.
[0003] Utility model patent CN216741531U discloses a smooth-surface blasting construction structure for tunnel excavation, including a tunnel excavation face and a construction device. The construction device includes a base, on which a first worktable is fixed by two first support columns. A second worktable is fixed to the base by two second support columns. The base also has two synchronously driven lifting cylinders. A third worktable is fixed to the output shaft of each lifting cylinder. A top platform mechanism is fixed between the two third worktables. The top platform mechanism includes two third support columns and two second support columns. The top of the three support columns is fixed with a top plate, and the bottom of the two third support columns is fixed with a bottom plate. The first, second and third support columns are equipped with multiple step plates to facilitate workers to climb. The construction device includes a first work platform, a second work platform, a third work platform and a top platform mechanism, which can drill multiple blast holes on the tunnel excavation face. In this patent, because the top of the tunnel is arc-shaped and the size decreases from bottom to top, the length of the first, second and third work platforms is fixed, making it difficult to provide support for drilling or loading blasting holes close to the tunnel sidewall.

During the movement of the telescopic mesh plate 1001, the locking slider 20 slides in the first locking groove and the second locking groove 19 respectively. After the telescopic mesh plate 1001 moves and abuts against the side wall of the tunnel, the connecting screw head 22 on the connecting rod 1101 is connected to the connecting screw sleeve 21, and then the connecting sleeve 23 is rotated to move towards each other, so that the locking head is inserted into the second locking groove 19, thereby connecting the adjacent The telescopic mesh panels 1001 are connected and support each other.

Similarly, the telescopic mesh plate 1001 is pushed along the support mesh plate 701 to abut against the tunnel sidewall, which fills the gap between the support mesh plate 701 and the tunnel sidewall. The connecting rod 1101 is used to support it on the ground and connect adjacent telescopic mesh plates 1001, thereby providing construction personnel with a stable and adjustable blasting construction platform. After the construction on the left side of the vertical support plate 201 is completed, the connecting rod 1101 is removed, and the telescopic mesh plate 1001 is pushed to the lower end of the support mesh plate 701. Then, the support frame 601 is pushed to the right side of the vertical support plate 201, and the telescopic mesh plate 1001 is removed and the connecting rod 1101 is installed to provide support for drilling holes and installing blasting charges on the tunnel face on the right side of the vertical support plate 201.
