Description

Technical Field

[0001] The present invention relates to the field of rail transit technology, and in particular to a structure co-built with rail transit and a municipal tunnel. Background Art

[0002] The co-construction structure of rail transit and municipal tunnels refers to an engineering form that spatially integrates rail transit tunnels such as subways and light rail with municipal infrastructure tunnels (such as integrated pipeline corridors, underground roads, drainage tunnels, etc.), and realizes intensive utilization and coordinated operation by sharing underground space, structures and construction resources.

[0003] The patent with patent announcement number CN214613530U relates to the field of rail transit technology. The patent provides a combined structure of a bridge, a municipal tunnel, and a comprehensive pipeline corridor, including a combined structure of a bridge, a municipal tunnel, and a comprehensive pipeline corridor, which is composed of at least a bridge superstructure, a pier cap beam, a tunnel top pier, a municipal tunnel top plate, a municipal tunnel bottom plate, a municipal tunnel side wall, a municipal tunnel comprehensive pipeline corridor shared side wall, a comprehensive pipeline corridor top plate, a comprehensive pipeline corridor bottom plate, a comprehensive pipeline corridor side wall, a comprehensive pipeline corridor middle partition wall, and a bridge pier. According to the actual situation of the project, the comprehensive pipeline corridor is located on one side of the municipal tunnel and is connected to the municipal tunnel through the shared side wall of the municipal tunnel comprehensive pipeline corridor to form an integral structure. The bridge is located on the upper part of the municipal tunnel and the comprehensive pipeline corridor and is connected to the municipal tunnel through the tunnel top pier. On the premise of ensuring that the various structures of the building are reasonably stressed and can operate normally, the utilization rate of the underground space is increased, the construction steps are simplified, the implementation period of the project is shortened, and the economic and social benefits of the project are improved.

[0004] In the above patent, the tunnel is connected to the municipal tunnel through the tunnel top pier, which increases the utilization rate of the underground space while ensuring that the various structures of the building are reasonably stressed and can operate normally. However, it is difficult to support and dampen the splicing area when splicing bridges and roads, which can easily cause the splicing to be excessively squeezed and vibrated during daily use, resulting in damage to the splicing or large gaps. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the present invention provides a co-construction structure of rail transit and municipal tunnel, which solves the problems raised in the above background technology.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a structure for co-construction of rail transit and municipal tunnels, comprising: a support column, a shock-absorbing block fixedly mounted on the top of the support column, a pavement splicing platform provided on the top of the shock-absorbing block, splicing teeth provided on the adjacent sides of the pavement splicing platform, an extension platform fixedly mounted on the adjacent sides of the pavement splicing platform, a shock-absorbing device, a structural reinforcement device, and a protective device provided on the top of the extension platform;

[0007] Among them, the shock absorbing device includes an elastic telescopic rod 1, a push rod, an inclined plane block 1, a pressure rod, a No. 1 hydraulic cylinder, a No. 2 hydraulic cylinder, a lifting plate, an elastic telescopic rod 2, a rubber shock absorbing plate and an inclined plane block 2. The elastic telescopic rod 1 is fixedly mounted on the top of the extension platform, the push rod is fixedly mounted on the top of the movable end of the elastic telescopic rod 1, the inclined plane block 1 is fixedly mounted on the top of the push rod, the pressure rod is fixedly mounted on the bottom of the push rod, the No. 1 hydraulic cylinder is fixedly mounted on the top of the extension platform, the No. 2 hydraulic cylinder is fixedly mounted on the top of the extension platform, the lifting plate is fixedly mounted on the top of the pushing end of the No. 2 hydraulic cylinder, and the elastic telescopic rod 2 is fixedly mounted on the top of the extension platform. The second inclined plane block is fixedly mounted on the top of the lifting plate, and the rubber shock-absorbing plate is fixedly mounted on the top of the second movable end of the elastic telescopic rod. The second inclined plane block is fixedly mounted on the pushing end of the No. 1 hydraulic cylinder. The splicing teeth contact and push the inclined plane block to start moving downward. The movement of the inclined plane block drives the push rod to start moving downward. The movement of the push rod drives the pressure rod to start moving downward. The pressure rod moves to contact and push the inclined plane block to start moving. The movement of the inclined plane block pushes the hydraulic rod of the No. 1 hydraulic cylinder to squeeze the liquid inside the No. 1 hydraulic cylinder through the hydraulic pipe into the inside of the No. 2 hydraulic cylinder. The hydraulic rod of the No. 2 hydraulic cylinder is pushed by the liquid in the No. 1 hydraulic cylinder to start moving upward.

[0008] According to the above technical solution, the No. 1 hydraulic cylinder and the No. 2 hydraulic cylinder are connected by a hydraulic pipe, and the interiors of the No. 1 hydraulic cylinder and the No. 2 hydraulic cylinder are filled with liquid. The sides of the pressure rod and the inclined plane block 2 that contact each other are set as inclined planes. By filling with liquid, it is ensured that the No. 1 hydraulic cylinder and the No. 2 hydraulic cylinder can work normally, and by setting the inclined plane, it is ensured that the pressure rod can smoothly push the inclined plane block 2 when moving.

[0009] According to the above technical solution, the structural reinforcement device includes a long rod, a base plate and a clamping block. The long rod is fixedly installed at the bottom of the lifting plate, the base plate is fixedly installed at the bottom of the long rod, and the clamping block is fixedly installed at the top of the base plate. When the lifting plate starts to move upward, the long rod is also driven to move upward. The movement of the long rod drives the base plate to move upward. The movement of the base plate drives the clamping block to move upward. The clamping block moves upward and is clamped into the slot at the bottom of the extension platform.

[0010] According to the above technical solution, the structural reinforcement device also includes an inclined rod, a slide rail, a sliding rod, an inclined block three and an arc plate. The inclined rod is fixedly installed on the bottom of the base plate, the slide rail is fixedly installed on the bottom of the extension platform, the slide rod is slidably installed inside the slide rail, the inclined block three is fixedly installed on the side of the slide rod away from the shock-absorbing block, and the arc plate is fixedly installed on the side of the slide rod away from the inclined block three. When the base plate starts to move upward, the inclined rod is driven to move upward, the inclined rod moves to contact and push the inclined block three to start moving, the inclined block three moves and drives the slide rod to start moving along the extension direction of the slide rail, the slide rod moves and drives the arc plate to start moving, and the arc plate moves and fully contacts the shock-absorbing block.

[0011] According to the above technical solution, the long rod passes through the extension platform, and a slot is provided at the bottom of the extension platform on the other side. The sides of the inclined rod and the inclined block three that contact each other are both set as inclined surfaces. By providing the slot, it is ensured that the block can limit the extension platform, and by setting the inclined surface, it is ensured that the inclined rod can smoothly push the inclined block three when moving.

[0012] According to the above technical solution, the protective device includes two rotating rods, a transmission belt, a connecting rod, a transmission rod and a guard plate. The two rotating rods are rotatably installed on the side of the extension platform close to the road surface splicing platform. The two rotating rods are connected through a transmission belt. One end of the connecting rod is fixedly installed on the surface of the inclined block three, and the other end of the connecting rod is fixedly installed on the bottom of the transmission belt. The transmission rod is fixedly installed on the top of the transmission belt. The guard plate is fixedly installed on the end of the transmission rod away from the transmission belt. The movement of the inclined block three drives the sliding rod to start moving and at the same time drives the connecting rod to start moving. The movement of the connecting rod drives the transmission belt to start rotating around the rotating rod. The rotation of the transmission belt drives the transmission rod to start moving. The movement of the transmission rod drives the guard plate to start moving.

[0013] According to the above technical solution, the protective device also includes a clamping rod and a clamping ring. The clamping rod is fixedly installed on the surface of the guard plate, and the clamping ring is fixedly installed on the front of the road splicing platform on the other side. When the guard plate starts to move, the clamping rod is also driven to move. The clamping rod moves and contacts the clamping ring. Under continuous movement, the clamping rod is deformed and passes through the clamping ring. After passing through the clamping ring, the clamping rod returns to its original state.

[0014] According to the above technical solution, the side of the clamping rod in contact with the clamping ring is set as a slope, and the guard plate is in contact with the road surface splicing platform. By setting the slope, it is ensured that the clamping rod can pass through the clamping ring smoothly when moving, and the contact ensures that the guard plate can provide complete protection.

[0015] The present invention provides a structure for co-construction of rail transit and municipal tunnels. It has the following beneficial effects:

[0016] (1) This invention provides shock-absorbing support to the joint by moving the rubber shock-absorbing plate upward to contact the splicing teeth, thereby absorbing and reducing vibrations and preventing vibrations from being transmitted to the surrounding areas, thereby reducing the impact on vehicles, pedestrians and surrounding buildings, reducing the impact of vibrations and noise on the driving experience, and improving the smoothness and comfort of driving. At the same time, the rubber shock-absorbing plate can provide additional cushioning to reduce impact and wear on the vehicle.

[0017] (2) This invention can help maintain the position and alignment of the roads on both sides during the splicing process by moving the card block upward and inserting it into the card slot at the bottom of the extension platform, ensuring that the joints at the splicing are smooth, avoiding uneven road surface and excessive wear caused by inaccurate splicing, and effectively preventing the roads on both sides from shifting or misaligning during splicing, thereby ensuring the stability of the road surface structure and avoiding cracks or unevenness caused by asymmetry in the future.

[0018] (3) This invention can increase the contact area of ​​the support area by moving the arc plate to fully contact the shock-absorbing block, thereby effectively dispersing the road load, reducing local pressure, and reducing the deformation or damage of the road surface caused by high load. At the same time, it can distribute the load more evenly to the support column, thereby reducing the local concentrated pressure at the joint and reducing the occurrence of cracks or early fatigue of the road surface structure.

[0019] (4) This invention can prevent dust, sand, and debris from entering the joints by moving the guard plate to block the gaps between the pavement joint platforms, thereby avoiding wear and erosion of the joints by these foreign objects, and reducing damage to the joints caused by the accumulation of external substances. At the same time, it can also improve the appearance of the pavement, making the pavement look smoother and more beautiful, and avoid obvious marks at the joints that affect the overall visual effect of the pavement.

[0020] (5) This invention allows the clamping rod to move and contact the clamping ring, and the clamping rod is deformed and passes through the clamping ring under continuous movement. After passing through the clamping ring, the clamping rod returns to its original state and restricts the guard plate to prevent it from moving or falling off under the action of traffic flow or external pressure, ensuring that the guard plate is always in the original shielding position, improving the stability and effectiveness of the guard plate, and making the installation of the guard plate easier, and making maintenance and replacement more convenient.

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] See also Figures 1-8 One embodiment of the present invention is: a rail transit and municipal tunnel co-construction structure, comprising: a support column 1, a shock absorbing block 2 is fixedly installed on the top of the support column 1, a road surface splicing platform 3 is provided on the top of the shock absorbing block 2, a splicing tooth 4 is provided on the side of the road surface splicing platform 3 close to each other, an extension platform 5 is fixedly installed on the side of the road surface splicing platform 3 close to each other, and a shock absorbing device is provided on the top of the extension platform 5;

The elastic telescopic rod 16 is fixedly mounted on the top of the extension platform 5, the push rod 7 is fixedly mounted on the top of the movable end of the elastic telescopic rod 16, the inclined plane block 18 is fixedly mounted on the top of the push rod 7, the pressure rod 9 is fixedly mounted on the bottom of the push rod 7, the No. 1 hydraulic cylinder 10 is fixedly mounted on the top of the extension platform 5, the No. 2 hydraulic cylinder 11 is fixedly mounted on the top of the extension platform 5, and the lifting plate 12 is fixedly mounted on the push rod 11. At the top of the moving end, the elastic telescopic rod 2 13 is fixedly mounted on the top of the lifting plate 12, the rubber shock-absorbing plate 14 is fixedly mounted on the top of the movable end of the elastic telescopic rod 2 13, and the inclined block 2 15 is fixedly mounted on the pushing end of the No. 1 hydraulic cylinder 10. The rubber shock-absorbing plate 14 moves upward to contact the splicing teeth 4 to provide shock-absorbing support for the splicing part, absorb and reduce vibration, and prevent vibration from being transmitted to the surroundings, thereby reducing the impact on vehicles, pedestrians and surrounding buildings, reducing the impact of vibration and noise on driving experience, and improving driving stability and comfort. At the same time, the rubber shock-absorbing plate 14 can provide additional cushioning to reduce impact and wear on the vehicle.

[0033] The No. 1 hydraulic cylinder 10 and the No. 2 hydraulic cylinder 11 are connected by a hydraulic pipe. The interiors of the No. 1 hydraulic cylinder 10 and the No. 2 hydraulic cylinder 11 are filled with liquid. The contact surfaces of the pressure rod 9 and the inclined plane block 2 15 are both set as inclined planes. By filling with liquid, it is ensured that the No. 1 hydraulic cylinder 10 and the No. 2 hydraulic cylinder 11 can work normally. By setting the inclined plane, it is ensured that the pressure rod 9 can smoothly push the inclined plane block 2 15 when moving.

[0034] When this embodiment is working: first, before splicing the road surface, the support column 1 must be completed and the shock-absorbing block 2 must be fully installed. Then, after all preparations are ready, the road surface splicing platform 3 is started to be spliced. The staff uses professional construction tools to align the splicing teeth 4 on both sides with each other's tooth gaps. After confirming the alignment, the road surface splicing platform 3 and the splicing teeth 4 are slowly moved into place. After moving into place, the road surface splicing platform 3 is completely installed and connected with the shock-absorbing block 2 and the support column 1. When the splicing teeth 4 on both sides begin to move and splice, the splicing teeth 4 contact and push the inclined surface block 1 8 to start moving downward. The movement of the inclined surface block 1 8 drives the top rod 7 to start moving downward. The movement of the top rod 7 drives the pressure rod 9 to start moving downward. The pressure rod 9 moves to contact and push the inclined surface block 2 15 to start moving. The movement of the inclined surface block 2 15 drives the No. 1 hydraulic The hydraulic rod of cylinder 10 squeezes the liquid inside hydraulic cylinder No. 10 through the hydraulic pipe into the inside of hydraulic cylinder No. 2 11. The hydraulic rod of hydraulic cylinder No. 2 11 is pushed by the liquid in hydraulic cylinder No. 10 and starts to move upward. The movement of the hydraulic rod of hydraulic cylinder No. 2 11 drives the lifting plate 12 to start moving upward. The movement of lifting plate 12 drives the elastic telescopic rod 2 13 to start moving upward. The movement of elastic telescopic rod 2 13 drives the rubber shock-absorbing plate 14 to start moving upward. The rubber shock-absorbing plate 14 moves upward and contacts the splicing teeth 4 to provide shock-absorbing support for the splicing part, absorb and reduce vibration, and prevent vibration from being transmitted to the surroundings, thereby reducing the impact on vehicles, pedestrians and surrounding buildings, reducing the impact of vibration and noise on driving experience, and improving driving stability and comfort. At the same time, the rubber shock-absorbing plate 14 can provide additional cushioning to reduce impact and wear on the vehicle.

[0035] See also Figures 1-8 Based on the above embodiment, in another embodiment of the present invention, a structural reinforcement device and a protective device are provided on the top of the extension platform 5.

[0036] The structural reinforcement device includes a long rod 151, a base plate 152 and a clamping block 153. The long rod 151 is fixedly installed at the bottom of the lifting plate 12, the base plate 152 is fixedly installed at the bottom of the long rod 151, and the clamping block 153 is fixedly installed on the top of the base plate 152. By moving the clamping block 153 upward and clamping it into the clamping slot at the bottom of the extension platform 5, it can help maintain the position and alignment of the roads on both sides during the splicing process, ensure that the joints at the splicing are flat, avoid uneven road surface and excessive wear due to inaccurate splicing, and effectively prevent the roads on both sides from shifting or misaligning during splicing, ensure the stability of the road surface structure, and avoid cracks or unevenness due to asymmetry in the future.

[0037] The structural reinforcement device also includes a sloped rod 154, a slide rail 155, a slide rod 156, a sloped block three 157 and a curved plate 158. The sloped rod 154 is fixedly mounted on the bottom of the base plate 152, the slide rail 155 is fixedly mounted on the bottom of the extension platform 5, the slide rod 156 is slidably mounted inside the slide rail 155, the sloped block three 157 is fixedly mounted on the side of the slide rod 156 away from the shock-absorbing block 2, and the curved plate 158 is fixedly mounted on the side of the slide rod 156 away from the sloped block three 157. By moving the curved plate 158 to fully contact the shock-absorbing block 2, the contact area of ​​the support area can be increased, thereby effectively dispersing the road load, reducing local pressure, and reducing deformation or damage of the road surface caused by high load. At the same time, the load can be more evenly distributed to the support column 1, thereby reducing the local concentrated pressure at the joint, reducing the occurrence of cracks or early fatigue of the road surface structure.

[0038] The long rod 151 passes through the extension platform 5, and a slot is provided at the bottom of the extension platform 5 on the other side. The contact surface of the inclined rod 154 and the inclined block three 157 are both set as inclined surfaces. By providing the slot, it is ensured that the block 153 can limit the extension platform 5, and by setting the inclined surface, it is ensured that the inclined rod 154 can smoothly push the inclined block three 157 when moving.

[0039] The protective device includes two rotating rods 161, a transmission belt 162, a connecting rod 163, a transmission rod 164 and a guard plate 165. The two rotating rods 161 are rotatably mounted on a side of the extension platform 5 close to the road surface splicing platform 3. The two rotating rods 161 are connected through the transmission belt 162. One end of the connecting rod 163 is fixedly mounted on the surface of the inclined block 3 157, and the other end of the connecting rod 163 is fixedly mounted on the bottom of the transmission belt 162. The transmission rod 164 is fixedly mounted on the top of the transmission belt 162. The guard plate 165 is fixedly mounted on the end of the transmission rod 164 away from the transmission belt 162. The guard plate 165 moves to block the splicing gap between the road surface splicing platforms 3, which can prevent dust, sand, stones, and debris from entering the splicing area, thereby avoiding wear and erosion of the joints by these foreign objects, reducing damage to the joints caused by the accumulation of external substances, and at the same time improving the appearance and cleanliness of the road surface, making the road surface look smoother and more beautiful, and avoiding obvious traces at the splicing area affecting the overall visual effect of the road surface.

[0040] The protective device also includes a clamping rod 166 and a clamping ring 167. The clamping rod 166 is fixedly installed on the surface of the guard plate 165, and the clamping ring 167 is fixedly installed on the front of the road splicing platform 3 on the other side. The clamping rod 166 moves to contact the clamping ring 167 and deforms and passes through the clamping ring 167 under continuous movement. After passing through the clamping ring 167, the clamping rod 166 returns to its original state and restricts the guard plate 165 to prevent it from moving or falling off under traffic flow or external pressure, ensuring that the guard plate 165 is always in the original shielding position, improving the stability and effectiveness of the guard plate 165, and at the same time making the installation of the guard plate 165 easier, and maintenance and replacement work also more convenient.

[0041] The side where the clamping rod 166 contacts the clamping ring 167 is set as an inclined surface, and the guard plate 165 contacts the road surface splicing platform 3. The inclined surface is set to ensure that the clamping rod 166 can pass through the clamping ring 167 smoothly when moving, and the contact ensures that the guard plate 165 can provide complete protection.

[0042] When this embodiment is working: when the lifting plate 12 starts to move upward, it drives the long rod 151 to start moving upward, and the movement of the long rod 151 drives the bottom plate 152 to start moving upward, and the movement of the bottom plate 152 drives the clamping block 153 to start moving upward, and the clamping block 153 moves upward and is clamped into the clamping groove at the bottom of the extension platform 5, which can help to maintain the position and alignment of the roads on both sides during the splicing process, ensure that the joints at the splicing are flat, avoid uneven road surface and excessive wear caused by inaccurate splicing, and effectively prevent the roads on both sides from shifting or misaligning during splicing, ensure the stability of the road surface structure, and avoid cracks or unevenness due to asymmetry in the future. At the same time as it moves upward, it drives the inclined rod 154 to start moving upward. The inclined rod 154 moves to contact and push the inclined block three 157 to start moving. The inclined block three 157 moves and drives the slide rod 156 to start moving along the extension direction of the slide rail 155. The slide rod 156 moves and drives the arc plate 158 to start moving. The arc plate 158 moves and fully contacts the shock-absorbing block 2, which can increase the contact area of ​​the support area, thereby effectively dispersing the road load, reducing local pressure, and reducing deformation or damage to the road surface caused by high load. At the same time, the load can be distributed more evenly to the support column 1, thereby reducing the local concentrated pressure at the joint, reducing the occurrence of cracks or early fatigue of the road surface structure.

[0043] When the inclined block 3 157 moves and drives the sliding rod 156 to start moving, it also drives the connecting rod 163 to start moving. The movement of the connecting rod 163 drives the transmission belt 162 to start rotating around the rotating rod 161. The rotation of the transmission belt 162 drives the transmission rod 164 to start moving. The movement of the transmission rod 164 drives the guard plate 165 to start moving. The guard plate 165 moves to block the splicing gap between the road surface splicing platforms 3, which can prevent dust, sand, and debris from entering the splicing area, thereby avoiding the wear and erosion of the joints by these foreign objects, reducing the damage to the joints caused by the accumulation of external substances, and at the same time improving the appearance of the road surface and making the road surface look smoother and more beautiful. , to avoid obvious marks at the joints affecting the overall visual effect of the road surface, when the guard plate 165 starts to move, it drives the clamping rod 166 to start moving, and the clamping rod 166 moves to contact the clamping ring 167 and deforms under continuous movement to pass through the clamping ring 167. After passing through the clamping ring 167, the clamping rod 166 returns to its original state and restricts the guard plate 165 to prevent it from moving or falling off under the action of traffic flow or external pressure, ensuring that the guard plate 165 is always in the original shielding position, improving the stability and effectiveness of the guard plate 165, and at the same time making the installation of the guard plate 165 easier, and maintenance and replacement work more convenient.
