Technical Field

[0001] The utility model relates to the technical field of tunnel fault reinforcement, in particular to a reinforcement and tightening support column for a tunnel fault fracture zone. Background Art

[0002] Since the fault fracture zone of the tunnel is relatively fragile, it needs to be reinforced with a special reinforcement structure. The main purpose of the reinforcement treatment is to improve the bearing capacity and anti-slip capacity of the tunnel structure, and prevent the buildings and bedrock from unevenly sinking due to excessive local stress or slipping due to insufficient anti-slip capacity.

[0003] The existing technology has the following deficiencies: the prior art publication number CN215890053U states that “a reinforcement support for a tunnel fault zone” “includes a support rod, a horizontal rod, a sleeve and a pull rod”;

[0004] The above structure can support the tunnel fault zone in the vertical direction through the support rods, and the horizontal rods can support the tunnel fault zone in the horizontal direction. The sleeve realizes the connection between the horizontal rods and the support rods. However, the structure does not make any improvements to the top and bottom of the support end, and still adopts the traditional single-body support scheme. This support method has uneven force and insufficient stability. Utility Model Content

[0005] In view of the deficiencies of the prior art, the utility model provides a reinforcement and tightening support column for the fault fracture zone of a tunnel, which solves the problem of uneven force on the supporting structure that exists today.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a reinforcement and tightening support for a fault fracture zone of a tunnel, comprising a main casing, a top casing, and a base, wherein the top casing is arranged above the main casing, and the base is arranged at the bottom end of the main casing;

[0007] A displacement column is provided inside the main sleeve, a connecting ring is provided on the periphery of the main sleeve, and a driving gear is provided on the upper end of the base;

[0008] The displacement column also includes a rack, a support plate, and a support arm. The rack is fixedly connected to the side end of the displacement column, the support plate is fixedly connected to the top end of the displacement column, and one end of the support arm is fixedly connected to the bottom of the support plate, and the other end is fixedly connected to the top sleeve.

[0009] As a preferred technical solution of the present invention, the support arms are provided with three groups, and the single body structure is composed of two groups of strips and one group of shafts, which are installed in an outwardly expanded state to wrap the support plate inside.

[0010] As an optimal technical solution of the present invention, the connecting ring also includes a supporting rod and a supporting foot. The supporting rod is movably connected to the side end of the connecting ring, and the supporting foot is movably connected to the bottom end of the supporting rod, and an axis structure is provided at the connection point passing through it.

[0011] As an optimal technical solution of the present invention, the driving gear also includes a crank and an axle seat bracket, the crank is movably connected to the side end of the driving gear, and the axle seat bracket is fixedly installed on the upper end of the base and movably connected to the side end of the driving gear.

[0012] As a preferred technical solution of the present invention, through-type rectangular groove structures are provided on both sides of the main body sleeve facing the driving gear.

[0013] As a preferred technical solution of the present invention, after the position of the displacement column is determined, it needs to be supplemented by an external bolt structure to fix the tooth groove of the driving gear.

[0014] As a preferred technical solution of the present invention, the support disk is made of a colloid material, and its single body structure is a disk-shaped body with an inward depression in the middle.

[0015] Compared with the existing technology, the utility model provides a reinforcement and tightening support for the fault fracture zone of a tunnel:

[0016] The reinforcement and tightening support pillar for the fault fracture zone of a tunnel is provided with a displacement column, a connecting ring, a driving gear, a rack and an axle seat bracket. When the structure is used, the operator carries it to the point inside the tunnel where support is required, and then moves the supporting connecting rod and the supporting foot to be close to the ground. By holding and turning the crank handle, the driving gear rotates under the support of the axle seat bracket. When the driving gear rotates, the rack meshed with its tooth groove is driven. At this time, the displacement column moves upward and pushes the support plate upward until the support plate is close to the top of the tunnel. After that, the support arm supports the support plate and disperses the pressure.

[0017] The above settings and processes can make the structure have the following beneficial effects:

[0018] Through the coordination of three sets of support arms, three sets of support links and support legs, the main casing and support plate can maintain uniform and stable dispersed pressure after being fixed in position. Through the coordination of the driving gear, rack and displacement column, the structure can quickly change its position, thereby ensuring high adaptability to the environment while stably bearing pressure and improving the stability of the support structure.
