Description

TECHNICAL AREA

[0001] This practical innovation belongs to the field of civil engineering and specifically concerns a fastening device used for installation in the rocks of excavated tunnels. BACKGROUND OF THE INVENTION

[0002] In front of the existing concrete wall, the fastening devices for rock stabilization treatment must be used. The existing fastening device is complex, has poor stability, cannot be freely adapted to the actual situation of the rock, and is very inconvenient to use. However, internal collapse can occur in the rock above the tunnel. The patent application CN202121151981.1, "Fastening device for loosened tunnel fixings," is also an increasingly mature technology that is connected by all fastening components in a detachable sequence.The support connection seat, acting as a support frame for the entire structure, plays the main supporting role, reinforcing the side plate component against the side wall of the excavated tunnel and reinforcing the cover plate component against the arched part of the excavated tunnel. This strengthens all parts of the excavated tunnel, improving the reinforcement stability of the reinforcement structure and the safety of the tunnel construction. However, the structure also has the following drawbacks: during support reinforcement, because the upper rock layer is in an organized fractured state, the collapse of the upper structure in the excavated environment will destroy the lower tunnel, leading to pressure at a specific point in the lower structure that affects the entire support structure. SUMMARY OF THE INVENTION

[0003] The purpose of this invention is to provide a reinforcement device for removing rocks in loosened tunnels, which aims to solve the existing technology of fixing a structural crack in the upper layer of the rock layer, the collapse of the upper structure in loosened environments destroying the lower tunnel, leading to a specific point in the lower structure that generates pressure and affects the problem of the entire supporting structure.

[0004] To achieve the aforementioned purposes, this practical new model offers the following technical solutions: including tunnel beams, the distribution of the outer wall of the tunnel beam has several external support plates, the upper part of the outer support plate has several external support plates, the upper side of the outer support plate is connected to an inclined support column, the inclined support column is connected to one end of the main support beam, the main support beam is connected to a main water column, the main water column is connected to a secondary support beam, the lower part of the secondary support beam has several support plates, the outer wall of the secondary support beam has a high protective beam.

[0005] In one embodiment of this practical novelty for the fastening device of rocks for soluble tunnel environments, the main water column is opened with a first hole at the end and the main water column is opened with a second hole at the connection with the main support beam.

[0006] In this program, the main support beam, the inclined support columns, the main water column, and the secondary support beams are welded together during construction, and the outer support slab is built outside the tunnel beam, filled by the main water column, which flows through the first holes into the main water column and fills the main support beams and the secondary support beams to form a support structure after condensation, in order to facilitate construction.

[0007] In one embodiment of a fastening device for use in rock-soluble tunnel systems, a first connecting hole is opened at the top of the inclined support columns, wherein the first connecting hole of the inclined support columns is tightly connected to the main support beam on both sides.

[0008] In this program, after the concrete filling, inclined support columns and outer support slab and main support beams form a stable support structure. When the upper solution creates the collapse of the shear force, the secondary support beams and the main water column and the main support beams form a network structure that distributes the gravity downwards, while the inclined support columns are supported between the main support beams and the outer support slab. At this point, the bearing slab forms a support structure between the secondary support beams, supports the gravity, and improves the overall strength of the support. This is used after the solution of the upper structure to the shear force following the modification of the practical new type of reinforcement device for the implementation of tunnel systems.

[0009] In this program, the concrete flows into the outer support slab, which is filled, and the inclined support columns are supported between the main support beam and the outer support slab, with the load-bearing slabs forming a support structure between the secondary support beams to assist gravity and improve the overall support strength.

[0010] In one embodiment of a fastening device for use in rock-soluble tunnel systems, an arch support beam is provided on the inside of the tunnel beam and a support plate is provided on both sides of the bottom of the arch support beam.

[0011] In this program, the inner side of the tunnel beam is supported by arched support beams to increase the support strength inside the tunnel; gravity is directed onto the support plate, forming an internal support structure.

[0012] In one embodiment of this practical novelty for the fastening device for red-soldered tunnel perimeters, a lower support plate is located on the bottom of the arch support beam, and several secondary supports are distributed between the lower support plate and the arch support beam.

[0013] In this scheme, the secondary supports support the base of the arched support beams and form several small support spaces.

[0014] In this practical embodiment of a fastening device for use in rock-soluble tunnel lining blocks, the adjacent side rays are distributed with a Berel ray.

[0015] In this scenario, the small support space formed between the secondary beams and the arch support beams is supported by the structure of a Berellet crossbeam to increase the support strength inside the tunnel.

[0016] Compared to existing technologies, the advantages of this utility model are: 1) By means of the inclined support columns and the outer support plate and the main support beam, to form the stable support structure when the upper solution creates the collapse of the shear force, the network structure of the secondary support beams and the main water column and the main support beam distributes the force of gravity downwards, while the inclined support columns between the main support beam and the outer support plate are supported, in this case the bearing plate forms a support structure between the secondary support beams, supports the force of gravity, improves the overall strength of the support, used to withstand the shear force that changes after the solution of the upper structure, the inclined support columns between the main support beam and the outer support plate are supported, in this case the bearing plate forms a support structure between the secondary support beams, supports the force of gravity, improves the overall strength of the 2) Support of the inner side of the tunnel beam by the arch support beam, support of the lower side of the arch support beam by the auxiliary supports, formation of a series of small support spaces, improvement of the support strength inside the tunnel, gravity on the support plate, formation of an internal support structure, the structure of the Barrett crossbeams supports the small support space between the auxiliary beams and the arch support beam to improve the support strength inside the tunnel.
