Description

Technical Field

[0001] The invention belongs to the technical field of tunnel construction, in particular to a tunnel using a corrugated steel plate arch structure for pouring concrete. Background Art

[0002] During tunnel construction, the inner wall of the culvert needs to be supported so that safer construction can be carried out inside the culvert. Corrugated steel was first used in the construction of drainage systems for road culverts. After years of development, underground passages, pipe culverts, water transmission systems, water storage systems, etc. formed by steel pipes have played an important role in highways, railways, airports, municipalities, industrial parks, flood and environmental protection projects, water pollution control and other fields.

[0003] A Chinese patent, publication number CN108915734A, discloses a corrugated steel-concrete composite support structure and its construction method. The structure comprises a circular arch corrugated steel plate, vertical wall corrugated steel plate, a steel mesh, and a base. The circular arch corrugated steel is bolted to the vertical wall corrugated steel plate, and a concrete base is cast at the ends of the vertical walls. Grouting holes are provided in the center of each corrugated steel plate, and superfluid concrete is poured between the corrugated steel plate and the surrounding rock.

[0004] In the existing arch structure of corrugated steel plates, when corrugated steel plates are used to support culverts, due to the complex environment inside the culvert, the stress positions of the corrugated steel plates when supporting the culvert are relatively complex, and it is easy for some positions of the corrugated steel plates to be subjected to greater stress, resulting in greater deformation of some positions of the corrugated steel plates.

[0005] To this end, the present invention provides a tunnel using a corrugated steel plate arch structure with poured concrete. Summary of the Invention

[0006] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0007] The technical solution adopted by the present invention to solve its technical problems is: the tunnel described in the present invention uses a corrugated steel plate arch structure poured with concrete, including a support frame; a corrugated steel plate body is fixedly connected to the inside of the support frame; a plurality of positioning holes are opened in the middle of the support frame; a spray-coated waterproof membrane is sprayed on the corrugated steel plate body; when in use, the support frames are distributed on the internal surface of the tunnel, and a plurality of support frames are assembled together so that the plurality of support frames and the corrugated steel plate body are assembled into a whole to protect and support the inner surface of the tunnel. After the support frames are assembled, the plurality of assembled support frames and the corrugated steel plate body are covered with a plain concrete secondary lining; by using a plurality of support frames and the corrugated steel plate body to support the interior of the tunnel, the stability of the tunnel during construction operations can be improved.

[0008] Furthermore, a plurality of metal cables are connected to the middle part of the support frame; an arc-shaped top plate is provided between the corrugated steel plate body and the metal cables; a support rod is hinged between the arc-shaped top plate and the metal cables; the corrugated steel plate body is supported by a plurality of metal cables, an arc-shaped top plate and a support rod provided on the corrugated steel plate body between the support frame. When the support frame and the corrugated steel plate body support the tunnel, the metal cables support the corrugated steel plate body through the support rod and the arc-shaped top plate, thereby improving the supporting stability of the corrugated steel plate body and reducing the degree of deformation of the corrugated steel plate body when the corrugated steel plate body is subjected to uneven extrusion. This arrangement can enhance the supporting stability of the corrugated steel plate body.

[0009] Furthermore, a plurality of drainage holes are provided in the middle of the arc-shaped top plate; the drainage holes pass through the arc-shaped top plate; by providing a plurality of drainage holes inside the arc-shaped top plate, when the corrugated steel plate body is covered with a second lining of plain concrete, part of the concrete can contact the corrugated steel plate body through the drainage holes. This arrangement can improve the stability of the contact between the arc-shaped top plate and the corrugated steel plate body when the concrete solidifies, reduce the problem of the arc-shaped top plate falling off from the corrugated steel plate body, and further improve the stability of the arc-shaped top plate when supporting the corrugated steel plate body.

[0010] Furthermore, a plurality of positioning teeth are fixed to the inside of the arc-shaped top plate; a first elastic metal rope is connected between the ends of the positioning teeth that are close to each other; by providing a plurality of positioning teeth and a first elastic metal rope in the middle of the arc-shaped top plate, when plain concrete is covered on the corrugated steel plate body, the positioning teeth and the first elastic metal rope can increase the contact area between the arc-shaped top plate and the concrete, thereby improving the stability of the arc-shaped top plate on the corrugated steel plate body.

[0011] Furthermore, a plurality of guide cavities are provided inside the arc-shaped top plate; a top cone is slidably connected inside the guide cavity; a plurality of second elastic metal ropes are connected to the middle of the first elastic metal rope; the middle of the second elastic metal rope bypasses a plurality of drainage holes and is connected to the top surface of the arc-shaped top plate; the middle of the second elastic metal rope is arranged to bypass the bottom of the top cone from the inside of the guide cavity; by providing a plurality of top cones on the arc-shaped top plate, in the process of the arc-shaped top plate being fitted to the corrugated steel plate body, the end of the top cone will first contact the corrugated steel plate body, and then when the metal cable continues to approach the corrugated steel plate body During the process, the top cone will pull the second elastic metal rope, and then tighten the first elastic metal rope, causing the first elastic metal rope to deform. At this time, the positioning teeth, the first elastic metal rope, the top cone and the second elastic metal rope can be placed between the arc-shaped top plate in a relatively tight state, further improving the stability of the arc-shaped top plate supporting the corrugated steel plate body. At the same time, the end of the top cone is used to support the corrugated steel plate body to increase the friction between the top cone and the corrugated steel plate body, which can improve the stability of the contact between the arc-shaped top plate and the corrugated steel plate body and reduce the problem of the arc-shaped top plate slipping on the corrugated steel plate body.

[0012] Furthermore, multiple third elastic metal ropes are connected between the middle part of the first elastic metal rope and the middle part of the metal cable; by connecting the third elastic metal rope between the first elastic metal rope and the metal cable, in the process of the top cone tightening the first elastic metal rope through the second elastic metal rope, the metal cable can be further tightened by the third elastic metal rope, thereby reducing the problem of loosening of the metal cable in the middle part of the support frame, improving the stability of the metal cable's control over the curved top plate, and further improving the stability of the contact between the curved top plate and the corrugated steel plate body.

[0013] Furthermore, an auxiliary top plate is fixedly connected to the middle of the metal cable; the auxiliary top plate is in contact with the corrugated steel plate body; the position of the auxiliary top plate corresponds to that of the curved top plate; by providing an auxiliary top plate in the middle of the metal cable, the corrugated steel plate body can be supported on the other side of the curved top plate, thereby improving the stability of the auxiliary top plate and the curved top plate in supporting the corrugated steel plate body at the same time, and reducing the problem of excessive deformation of the corrugated steel plate body when the force is uneven.

[0014] Furthermore, a plurality of rubber rods are fixedly connected to one side of the middle part of the auxiliary top plate close to the corrugated steel plate body; by providing the rubber rods in the middle part of the auxiliary top plate, the stability of the auxiliary top plate when in contact with the corrugated steel plate body can be improved, and the slipping problem between the auxiliary top plate and the corrugated steel plate body can be reduced.

[0015] Furthermore, a fourth elastic metal rope is connected between the support rods that are close to each other; the middle part of the fourth elastic metal rope passes through the auxiliary top plate and slides with the auxiliary top plate; the middle part of the fourth elastic metal rope passes through the middle parts of multiple rubber rods and the auxiliary top plate in turn; by arranging a fourth elastic metal rope inside the auxiliary top plate, when the second elastic metal rope tightens the positioning teeth and the third elastic metal rope, the fourth elastic metal rope can be made tighter at the same time. At this time, the fourth elastic metal rope can press the rubber rod tightly against the corrugated steel plate body, thereby increasing the contact force between the rubber rod and the corrugated steel plate body, and further improving the stability of the contact between the auxiliary top plate and the corrugated steel plate body.

[0016] Furthermore, positioning rods are connected between the multiple support rods that are close to each other; the middle part of the positioning rods is connected to the auxiliary top plate; by connecting the positioning rods between the middle part of the auxiliary top plate and the support rods, the auxiliary top plate can support the corrugated steel plate body more stably, reducing the problem of deflection of the auxiliary top plate between the metal cable and the corrugated steel plate body.

When the plate body 11 is subjected to uneven force, the deformation amplitude is too large. By providing a rubber rod 8 in the middle of the auxiliary top plate 7, the stability of the auxiliary top plate 7 when in contact with the corrugated steel plate body 11 can be improved, and the problem of slippage between the auxiliary top plate 7 and the corrugated steel plate body 11 can be reduced. By providing a fourth elastic metal rope 9 inside the auxiliary top plate 7, when the second elastic metal rope 52 tightens the positioning teeth 4 and the third elastic metal rope 6, the fourth elastic metal rope 9 can be tightened at the same time. At this time, the fourth elastic metal rope 9 can press the rubber rod 8 tightly against the corrugated steel plate body 11, increasing the contact force between the rubber rod 8 and the corrugated steel plate body 11, thereby further improving the stability of the contact between the auxiliary top plate 7 and the corrugated steel plate body 11. By connecting a positioning rod 91 between the middle of the auxiliary top plate 7 and the support rod 22, the auxiliary top plate 7 can support the corrugated steel plate body 11 more stably, reducing the problem of the auxiliary top plate 7 deflecting between the metal cable 2 and the corrugated steel plate body 11.
