Description

Technical Field

[0001] The utility model relates to the technical field of tunnel construction, in particular to a supporting structure for tunnel construction. Background Art

[0002] When constructing an already excavated tunnel, it is sometimes necessary to temporarily support certain weak parts of the tunnel to ensure safe construction.

[0003] Common temporary support devices for tunnels are gate-shaped or well-shaped temporary support devices, which mainly use arched plates to fit on the top wall of the tunnel, thereby playing a role in supporting and preventing stones from falling. However, this structure usually uses a large number of rods or plates to be temporarily connected by welding or bolts, so its installation and disassembly are very cumbersome. In addition, there are too many structures under the arch plate, making the passage very narrow and difficult for people and equipment to pass through. Therefore, it is necessary to design a support structure that can not only be installed efficiently, but also allow people and equipment to pass smoothly. Utility Model Content

[0004] The utility model aims to provide a supporting structure for tunnel construction, which is not only easy to install but also can leave enough space for people and equipment to pass through.

[0005] The embodiments of the utility model are realized through the following technical scheme: the support structure for tunnel construction of the utility model comprises a pair of relatively arranged vertical plates, a horizontal plate arranged at the lower end between the pair of said vertical plates, an arc-shaped arch plate arranged at the upper end between the pair of said vertical plates, a pair of support rods respectively arranged at both ends of the arch plates, insertion holes provided in the support rods, a first slide groove provided in one side of the vertical plates close to the arch plates, a fixed block, and a pair of top plates hinged to the fixed blocks at the same time; the lower end of the support rod abuts against the horizontal plate, one of the support rods is slidably provided in one of the first slide grooves, and one of the top plates is detachably inserted in one of the insertion holes.

[0006] Furthermore, a clearance hole for the arch plate to pass through is provided on the side of the transverse plate.

[0007] Furthermore, a second sliding groove is provided on the upper side of the transverse plate, and the lower end of the support rod is slidably disposed in the second sliding groove.

[0008] Furthermore, it also includes a pair of cross-arranged connecting rods; one end of the connecting rod is connected to the inner wall of the arch plate, and the other end is connected to the end of the arch plate.

[0009] Furthermore, a connecting block is provided at the lower side of the connection of the pair of connecting rods; the connecting block is arranged directly above the fixing block.

[0010] Furthermore, a slot is provided on the lower side of the connecting block.

[0011] Furthermore, a plurality of support plates are provided on the upper side of the arch plate, and the plurality of support plates are distributed along the circumferential direction of the arch plate.

[0012] The technical solution of the embodiment of the utility model has at least the following advantages and beneficial effects: the support structure for tunnel construction of the utility model, when in use, first fix a pair of vertical plates to the wall surfaces on both sides of the tunnel by bolts, then insert the support rods at both ends of the arch plate into the first slide groove on the vertical plate, then insert the ends of a pair of push rods into the jacks, place a device with a lifting function such as a jack on the fixed block, and make the telescopic rod of the jack support the arch plate and lift it. During the lifting process, the telescopic rod can push the arch plate upward, and can also push the support rod toward the vertical plate through the push rod, and lift the arch plate through the support rod, so that the arch plate can be close to the tunnel wall, and then fix the support rod, so that not only the entire installation process is very convenient and efficient, but also the overall stability is good, and a large enough gap is left on the lower side of the overall structure, enough for personnel or equipment to pass through.
