Description

Technical Field

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

[0002] Tunnel construction refers to the method of designing and constructing underground projects. During tunnel construction, support structures are required to avoid tunnel collapse and ensure construction safety.

[0003] Most of the existing support structures are simply inserted into the soil for fixed support and protection. When the two sides of the tunnel are damaged or deformed and collapsed, it is impossible to adjust the support on both sides of the tunnel. The lack of stability can easily threaten the safety of personnel. At the same time, working in an environment with insufficient light can easily cause unclear vision due to uneven lighting brightness, thereby reducing work efficiency.

[0004] Therefore, in view of the fact that the above-mentioned existing support structures cannot support and adjust both sides of the tunnel, lack stability, and easily threaten the safety of personnel, and working in an environment with insufficient light is prone to cause unclear vision due to uneven lighting brightness, thereby reducing work efficiency, a high-stability support structure for tunnel construction has been developed. The setting of fixed components makes it convenient for construction personnel to adjust according to the width of the tunnel, ensure the stability of support and protection on both sides of the tunnel, and improve safety. The setting of lighting components makes the lighting brightness more sufficient and uniform. Even when working in an environment with insufficient light, it can still ensure visual clarity and improve work efficiency. Utility Model Content

[0005] In order to overcome the problem that the existing support structure cannot support and adjust both sides of the tunnel, lacks stability, and easily threatens the safety of personnel, working in an environment with insufficient light can easily cause unclear vision due to uneven lighting brightness, thereby reducing work efficiency.

[0006] The technical solution of the utility model is: a support structure for high-stability tunnel construction, including a base, a support seat and a hydraulic lifting column, and also including a support frame, a fixing component and a lighting component. The support seat is installed on the top surface of the base, a fixing component is arranged inside the support seat, a hydraulic lifting column is installed on the upper surface of the support seat, both sides of the bottom end of the support frame are fixedly connected to the top of the hydraulic lifting column, and the lighting component is installed on the bottom end of the inner wall of the support frame by means of a spring pin.

[0007] Preferably, the setting of the fixed components makes it convenient for construction workers to adjust according to the width of the tunnel, thereby ensuring the stability of the support and protection on both sides of the tunnel and improving safety. The setting of the lighting components makes the lighting brightness more sufficient and uniform. Even when working in an environment with insufficient light, the clarity of vision can still be guaranteed, thereby improving work efficiency. At the same time, the spring pin clamping installation facilitates the installation and disassembly of the lighting components. The setting of the hydraulic lifting column allows the support frame to be raised and lowered, thereby facilitating the support of tunnels of different heights.

[0008] Preferably, the support frame is a semi-arc shape with a cavity structure, and a first anti-slip layer is provided on the top surface of the support frame. The semi-arc shape of the support frame better fits the design of the tunnel entrance, and the cavity structure facilitates the installation of the lighting component in the support frame for lighting. The provision of the first anti-slip layer increases the friction of the support frame when supporting, avoids large movement, and improves stability.

[0009] Preferably, the inner side of the support seat is provided with a circular through hole, the outer side of the support seat is provided with a slot, and the slot is elliptical in shape, and the two sides of the fixing component are respectively used to conveniently adjust the width of both sides of the tunnel through the through hole and the slot.

[0010] Preferably, the fixing assembly includes a rocking wheel, a first gear, a second gear, a fixing plate, a bidirectional screw, a connecting rod and an adjusting block. The end of the rocking wheel close to the support seat passes through the through hole and is rotatably connected to the first gear. A bidirectional screw is provided on the inner wall of the support seat. The upper and lower sides of the bidirectional screw are threadedly connected to the adjusting block. The second gear is provided in the middle of the outer wall of the bidirectional screw, and the second gear is meshed with the first gear. The end of the adjusting block close to the slot is hingedly connected to the connecting rod, and the end of the connecting rod away from the adjusting block passes through the slot and is hingedly connected to the fixing plate. The construction workers drive the first gear to rotate by using the rocking wheel, and the second gear meshed with the first gear also starts to rotate synchronously and drives the bidirectional screw to rotate at the same time. The adjusting block on the bidirectional screw also rotates and drives the fixing plate to move through the connecting rod, so that the fixing plate can be tightly fixed to both sides of the tunnel to improve stability.

[0011] Preferably, a second anti-slip layer is provided on the surface of one side of the fixed plate away from the support seat, and the first anti-slip layer and the second anti-slip layer are both made of rubber. Rubber is a highly elastic polymer material with reversible deformation. It is characterized by being elastic at room temperature and being able to produce larger deformation under very small external force, and being able to quickly return to its original state when the external force is removed, so that it can fit better when supporting and protecting the tunnel, avoiding movement during work, and ensuring the safety and stability of construction.

[0012] Preferably, the lighting assembly includes a mounting plate, a rotating bracket, a support rod, a lamp board and a lighting lamp. The mounting plate is installed on the top of the spring pin, and rotating brackets are arranged on both sides of the upper surface of the mounting plate. The light board is rotatably connected to the rotating bracket through the support rod, and the lighting lamp is installed on the surface of the light board away from the rotating bracket. The mounting plate is clamped and installed on the bottom end of the inner wall of the support frame by the spring pin. When maintenance and inspection are required, the lighting assembly can be conveniently installed and disassembled. The setting of the rotating bracket can facilitate the angle adjustment of the light board, and timely adjustments can be made according to different ambient light.

[0013] Preferably, two lighting components are provided and symmetrically distributed on the inner side of the support frame, so that a larger range can be covered during lighting, meeting the needs of construction, enabling construction workers to see the surrounding environment more clearly, improving work efficiency, and ensuring construction safety.

[0014] Beneficial effects of the utility model:

[0015] 1. The setting of fixed components makes it easy for construction workers to adjust according to the width of the tunnel, ensuring the stability of the support and protection on both sides of the tunnel and improving safety. The setting of lighting components makes the lighting brightness more sufficient and uniform. Even when working in an environment with insufficient light, it can still ensure the clarity of vision and improve work efficiency. At the same time, the spring pin clamping installation makes it easy to install and disassemble the lighting components. The setting of hydraulic lifting columns can make the support frame rise and fall, which is convenient for supporting tunnels of different heights;

[0016] 2. Both the first anti-slip layer and the second anti-slip layer are made of rubber. Rubber is a highly elastic polymer material with reversible deformation. It is elastic at room temperature and can produce large deformation under very small external force. When the external force is removed, it can quickly return to its original state, so that when supporting and protecting the tunnel, it can fit better and avoid movement during work, thus ensuring the safety and stability of construction;

The setting of the fixing component is convenient for construction personnel to adjust according to the width of the tunnel, so as to ensure the stability of the support and protection on both sides of the tunnel and improve the safety. The setting of the lighting component makes the lighting brightness more sufficient and uniform, and can still ensure the clarity of vision even when working in an environment with insufficient light, thereby improving the work efficiency.

[0029] Then, the placement plate 18 is clamped and installed on the bottom end of the inner wall of the support frame 4 through the spring pin 5. According to the required lighting range, the angle of the light board 21 is adjusted by rotating the bracket 19 to meet the construction needs, so that the construction workers can see the surrounding environment more clearly, improve work efficiency, and ensure construction safety;

[0030] Finally, the support frame 4 is raised and lowered by the hydraulic lifting column 3 to facilitate the support of tunnels at different heights, and then the first gear 10 is driven to rotate by using the rocker wheel 9.
