Description

Technical Field

[0001] The utility model relates to the technical field of connecting passages, and particularly relates to a connecting passage structure for a subway tunnel and a highway tunnel. Background Art

[0002] The statements herein only provide background art related to the utility model, and do not necessarily constitute prior art.

[0003] With the continuous development of urban construction, a certain number of subway tunnels and highway tunnels will be built underground in urban expressways or main roads to improve the overall traffic capacity and traffic efficiency of the roads, and at the same time relieve the congestion of expressways or main roads on land.

[0004] In the prior art, adjacent tunnels located underground are connected through connecting passages, which play important roles such as escape passages and vehicle transfer passages; however, the current connecting passages are generally used to connect tunnels of the same type, and due to the different structures and standards of subway tunnels and highway tunnels, the current connecting passages are not suitable for connecting subway tunnels and highway tunnels.

[0005] At the same time, subway tunnels, highway tunnels and connecting passages are all set below the ground surface. Due to the complexity of underground current branches and the complexity of industrial water pipe routes in the stratum, water seepage is likely to occur, resulting in cracks on the supporting surface of the connecting passage, seriously affecting the stability and durability of the supporting surface; and currently, the inspection of cracks on the supporting surface of the connecting passage is carried out manually at regular intervals, so there are still certain safety risks for the connecting passage. Summary of the Utility Model

[0006] The technical problem to be solved by the utility model is to provide a connecting passage structure for a subway tunnel and a highway tunnel, which can realize the stable connection between the subway tunnel and the highway tunnel, and at the same time can timely detect cracks on the supporting surface of the connecting passage to avoid safety accidents such as collapse and water leakage.

[0007] The purpose of the present utility model is to provide a connection passage structure for a subway tunnel and a highway tunnel. The subway tunnel and the highway tunnel are connected through a connecting tunnel. The connection passage structure includes an overlapping structure inner sleeve load-bearing layer, inner edge anchor bolts, an inner sleeve layer, two groups of electric guide rails, an arc chain track, and an inspection component. The overlapping structure inner sleeve load-bearing layer is embedded inside the connecting tunnel. The inner edge anchor bolts are fixedly connected to the outer surface of the overlapping structure inner sleeve load-bearing layer and extend into the connecting tunnel. The inner sleeve layer is arranged on the side of the overlapping structure inner sleeve load-bearing layer away from the connecting tunnel, and a gap is formed between the inner sleeve layer and the overlapping structure inner sleeve load-bearing layer. The two groups of electric guide rails are symmetrically arranged in the gap along the direction of the connecting tunnel. The arc chain track is arranged in the gap and is located above the electric guide rails. The two ends of the arc chain track are respectively fixedly connected to the two groups of electric guide rails. The inspection component is fixedly connected to the arc chain track.

[0008] As a further technical solution, the inspection component includes a spring, a placement plate, side vertical plates, and a radar detector. One end of the spring is fixedly connected to the arc chain track, and the other end of the spring is fixedly connected to the lower surface of the placement plate. The radar detector is arranged on the placement plate, and side vertical plates are arranged on both sides of the radar detector.

[0009] As a further technical solution, the inspection component further includes a universal ball and a contact wheel. The universal ball is arranged at the top end of the side vertical plate, and the contact wheel is fixedly connected to the universal ball.

[0010] As a further technical solution, the length of the inner sleeve layer along the direction of the connecting tunnel is shorter than the length of the overlapping structure inner sleeve load-bearing layer, so that gaps are left between the two ends of the inner sleeve layer and the edges of the overlapping structure inner sleeve load-bearing layer on the same side.

[0011] As a further technical solution, an inner concave layer is arranged in the gap area. The shape of the inner concave layer is the same as the shape of the gap formed between the inner sleeve layer and the overlapping structure inner sleeve load-bearing layer.

[0012] As a further technical solution, through holes are opened at the top ends of the inner concave layer close to the edges of the connecting tunnel on the same side, and instrument slots are opened at the top and bottom ends of the overlapping structure inner sleeve load-bearing layer in the same vertical direction as the through holes. Motors are arranged in the instrument slots, and the motors in the top instrument slots and the motors in the bottom instrument slots in the same vertical direction are fixedly connected through connecting columns.

[0013] As a further technical solution, a rotatable inner blocking door is arranged on the connecting column. Universal wheels are symmetrically arranged at the bottom ends on both sides of the rotatable inner blocking door. And an annular guiding slot is arranged at the bottom end of the overlapping structure inner sleeve load-bearing layer, and the universal wheels are nested in the annular guiding slot.

[0014] As a further technical solution, first slotted frames and second slotted frames are respectively opened on both sides of the rotatable internal door stopper at the same level.

[0015] As a further technical solution, a display rack bar is arranged in the first slotted frame. One end of the display rack bar is fixedly connected to the rotatable internal door stopper, and the other end of the display rack bar is fixedly connected to a clamping column; limiting grooves are opened on the upper and lower sides of the clamping column.

[0016] As a further technical solution, electric push rods are arranged at the joints of the upper and lower sides of the second slotted frame and the rotatable internal door stopper, and limiting bumps are arranged on the electric push rods.

[0017] Advantages of the above one or more technical solutions:

[0018] (1) In this embodiment, by providing an inner edge anchor rod with an outward extension barb structure, the overlapping structure inner sleeve load-bearing layer is embedded in the connecting tunnel. At the same time, by extending the inner edge anchor rod of the outward extension barb structure into the rock and soil layer of the connecting tunnel, the friction between the inner edge anchor rod and the rock and soil layer is increased by using the outward extension barb, so as to improve the tensile bearing capacity of the inner edge anchor rod, and the tight connection between the subway tunnel and the highway tunnel is realized through the connection passage structure.

[0019] (2) In this embodiment, by arranging the inner sleeve layer inside the overlapping structure inner sleeve load-bearing layer and forming a gap therebetween, according to the electric track, arc chain track and inspection components arranged in the gap, the support surface of the overlapping structure inner sleeve load-bearing layer can be inspected, and whether there are cracks on the support surface can be found in time, so as to repair the cracks in time, thus avoiding the sudden occurrence of safety accidents such as collapse and water leakage.

Specific implementation manner

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying Figure 1-10 drawings.

[0034] Embodiment 1

[0035] Referring to Figure 1 , the subway tunnel 1 and the highway tunnel 2 are two underground tunnels that are close to each other and parallel to each other, and the subway tunnel 1 and the highway tunnel 2 are connected through a connecting tunnel 3; among them, the connecting tunnel 3 is only an arched hole formed by excavation, and a corresponding connecting passage needs to be constructed inside the connecting tunnel 3 to support the connecting tunnel 3 and at the same time realize the connection between the subway tunnel 1 and the highway tunnel 2.

[0036] However, the current connecting passages are usually used to connect the same type of tunnels, and no connecting passage that can connect two different types of tunnels has been proposed; due to the differences in tunnel structures, materials used, and protection levels between the two different types of tunnels, the current connecting passages for the same type of tunnels are not suitable for connecting two different types of tunnels. Taking the subway tunnel 1 and the highway tunnel 2 as examples, this embodiment proposes a connecting passage that can connect two different types of tunnels, so as to stably connect the subway tunnel 1 and the highway tunnel 2.

[0037] Referring to Figure 2 , this embodiment proposes a connecting passage structure for a subway tunnel and a highway tunnel, including an overlapping structure inner sleeve load-bearing layer 25, inner edge anchor bolts 26, an inner sleeve layer 18, two groups of electric guide rails 30, an arc chain track 19, and an inspection component. And Figure 2 the overlapping structure inner sleeve load-bearing layer 25 in

[0038] is for the convenience of display. In actual application, both ends of the overlapping structure inner sleeve load-bearing layer 25 can be fitted with both ends of the connecting tunnel 3.

[0039] Meanwhile, an inner edge anchor rod 26 is fixedly connected to the outer surface of the inner bearing layer 25 within the overlapping structure. The inner edge anchor rod 26 is a columnar structure with a cylindrical end and a conical end. Among them, the cylindrical end of the inner edge anchor rod 26 is fixedly connected to the outer surface of the inner bearing layer 25 within the overlapping structure, while the conical end extends into the rock and soil layer of the connecting tunnel 3 and cooperates with the inner bearing layer 25 of the overlapping structure, thereby further fixing the inner bearing layer 25 of the overlapping structure inside the connecting tunnel 3 and increasing the tightness between the inner bearing layer 25 of the overlapping structure and the connecting tunnel 3.

[0040] In addition, extension barbs 29 are provided on the surface of the conical structure of the inner edge anchor rod 26. By extending the extension barbs 29 into the rock and soil layer, the friction between the inner extension anchor rod 26 and the rock and soil layer is increased, thereby improving the tensile bearing capacity of the inner extension anchor rod 26 and increasing the effective range of the inner extension anchor rod 26. At the same time, the setting of the extension barbs 29 can disperse the stress in the area where the inner extension anchor rod 26 contacts the soil surface, reduce the stress concentration at the end of the inner extension anchor rod 26, help reduce the risk of fracture or deformation of the inner extension anchor rod 26, improve the stability and vibration resistance of the connection passage structure, and effectively enhance the stability and durability of the connection passage.

[0041] By providing the inner bearing layer 25 of the overlapping structure and the inner extension anchor rod 26 with extension barbs 29, the connection passage can be stably nested in the connecting tunnel 3. Compared with ordinary connection passages, this passage has better supporting ability and stable connection ability, thus realizing the connection between different types of tunnels and being not affected by different construction conditions and standard parameters between different types of tunnels.

[0042] Considering that the inspection of the support surface of the connection passage is still carried out manually at regular intervals to detect whether there are cracks on the support surface, this makes it impossible to timely discover the cracks on the support surface. The existence of cracks will lead to safety accidents such as water seepage in the connection passage, affecting the stability and durability of the connection passage and making the connection passage at risk of safety accidents. In order to be able to timely discover the cracks on the support surface of the connection passage, the following technical solution is adopted in this embodiment.

[0043] Refer to Figure 3 , the inner sleeve layer 18 is arranged on the side of the inner bearing layer 25 of the overlapping structure away from the connecting tunnel 3 and forms a gap with the inner bearing layer 25 of the overlapping structure. Among them, the shape of the gap is also an arched structure.

[0044] In the gap of the arch structure, two sets of electric guide rails 30 are provided; the two sets of electric guide rails 30 are symmetrically arranged in the gap along the direction of the connecting tunnel 3 and are fixedly connected to the side walls of the inner load-bearing layer 25 and the inner layer 18 of the overlapping structure; in order to ensure the supporting force and stability of the inner load-bearing layer 25 and the inner layer 18 of the overlapping structure, the gap below the electric guide rails 30 can be filled with lightweight concrete.

[0045] Meanwhile, an arc-shaped chain track 19 is provided in the gap, and both ends of the arc-shaped chain track 19 are fixedly connected to the two sets of electric guide rails 30 respectively. Specifically, in this embodiment, the electric guide rail 30 adopts an automatic electric guide rail, which includes a track component and a moving platform component (including a moving platform plate) running on the track component. At the same time, the electric guide rail 30 can be controlled by a driving motor through wireless communication; and the arc-shaped chain track 19 is arranged in the gap above the electric guide rail 30.

[0046] The arc-shaped chain track 19 adopted in this embodiment includes an arc-shaped shell, two chains, a forward and reverse motor, and four gears; among them, the arc-shaped shell is an arc-shaped box structure without an upper surface, and the two chains respectively form a chain track loop and are arranged horizontally and parallelly inside the arc-shaped shell, and a single chain track loop is located in the same vertical plane. At the same time, in order to ensure the arc state of the chain track loop, a certain number of pressing wheels can be horizontally arranged inside the arc-shaped shell and are located at the lower ends of the upper and lower chains in the chain track loop, so as to ensure the arc state of the chain track loop.

[0047] The four gears are respectively arranged at both ends of the two chain track loops, and the gears are provided with tooth grooves matching the grooves between adjacent joints in the chain, so as to ensure that both ends of the chain track loop are nested on the gears and fixed. At the same time, the two gears on the same side are nested on the central rotating shaft of the forward and reverse motor according to the central through hole, so as to realize that the forward and reverse motor drives the chain track loop to rotate through the gears; and the motor can be fixed inside the arc-shaped shell by welding, bonding or a limiting groove, and is equipped with corresponding power equipment, such as a battery, etc.

[0048] In this embodiment, a forward and reverse motor is only arranged on one side; the two gears on the other side can be nested on the same steel pipe, and both ends of the steel pipe are welded to the side edges inside the arc-shaped shell; at the same time, another set of forward and reverse motors can also be arranged in the same way. In order to ensure that the position of the gear on the central rotating shaft of the forward and reverse motor or the steel pipe remains unchanged, limit blocks can be installed on both sides of the gear to limit the position of the gear.

[0049] In addition, the arc-shaped chain track 19 passes through both ends of the arc-shaped housing and is fixed to the platform plate in the moving platform assembly of the two-sided electric guide rails 30 by welding. Thus, the two groups of electric guide rails 30 can drive the arc-shaped chain track 19 to move horizontally along the connecting tunnel 3.

[0050] Referring to Figure 3-4 , an inspection component is arranged in the gap, and the inspection component is fixedly connected to the arc-shaped chain track 19. Specifically, the inspection component includes a spring 24, a placement plate 20, side vertical plates 21, and a radar detector 23. Among them, the spring 24 is in a vertical state, and the lower end of the spring 24 is welded to the connecting joint of the upper-side chain in the chain track loop of the arc-shaped chain track 19. And in the same way, the spring 24 is fixedly connected to the two chain track loops.

[0051] The upper end of the spring 24 is fixedly connected to the lower surface of the placement plate 20 by welding; through the above settings, the arc-shaped chain track 19 can drive the placement plate 20 to perform an arc-shaped movement in the vertical direction; at the same time, combined with the two groups of electric tracks 30 on both sides of the arc-shaped chain track 19, the placement plate 20 can reach any position in the gap.

[0052] Considering that the lower end of the spring 24 is connected to the upper-side chain in the chain track loop, infrared sensors can be arranged at appropriate positions at both ends inside the arc-shaped housing of the arc-shaped chain track 19 to detect both ends of the placement plate 20, so as to regulate the rotation of the forward and reverse motors, thereby ensuring the normal operation of the arc-shaped chain track 19 driving the placement plate 20.

[0053] At the same time, the radar detector 23 is arranged on the placement plate 20, and side vertical plates 21 are arranged on both sides of the radar detector 23 for fixing the radar detector 23. Through the above solution, structures such as the electric guide rail 30 and the arc-shaped chain track 19 are used to drive the radar detector 23 to reach any position on the upper surface support surface of the inner sleeve load-bearing layer 25 of the overlapping structure, and at the same time, the radar detector 23 can be used to detect whether there are cracks or water seepage phenomena on the support surface.

[0054] In order to improve the detection accuracy of the radar detector 23 and accurately detect cracks on the support surface, the inspection component further includes a universal ball 27 and a contact wheel 22. Among them, the universal ball 27 is nested at the top of the side vertical plate 21, and the contact wheel 22 is fixedly connected to the universal ball 27 through a bracket and is located between the universal ball 27 and the overlapping structure inner sleeve bearing layer 25. At the same time, the contact wheel 22 is in contact with the universal ball 27 and rotates through friction. By setting the universal ball 27, the contact wheel 22 and the spring 24, the radar detector 23 can be attached to the surface of the overlapping structure inner sleeve bearing layer 25 during operation. On the one hand, it increases the flexibility of the radar detector 23 during movement and avoids bumping and damage problems. On the other hand, it enables the radar detector 23 to more accurately and carefully detect cracks on the upper surface of the overlapping structure inner sleeve bearing layer 25, thereby avoiding the occurrence of safety accidents.

[0055] Among them, the radar detector 23 emits high-frequency electromagnetic waves through one antenna and receives the electromagnetic waves reflected by the underground medium through the other antenna. When the electromagnetic wave signal encounters different medium interfaces, light reflection and transmission occur. According to parameters such as the arrival time and amplitude intensity of the reflected signal, radar map data such as the position structure and shape in the connection channel are deduced. Then, the radar map is processed and analyzed through an external computer device. Finally, it is determined whether there are disease types and risks such as crack points and water seepage points in the overlapping structure inner sleeve bearing layer 25 in the connection channel, as well as the spatial position, avoiding the instability in the manual detection process. Using the detection equipment can improve the safety during the use of the connection channel, promptly repair the dangerous points, and avoid the sudden occurrence of safety accidents such as collapse and water leakage. The above solution is a way to detect cracks on the support surface through the radar detector 23.

[0056] In this embodiment, the length of the inner sleeve layer 18 along the direction of the connection tunnel 3 is shorter than the length of the overlapping structure inner sleeve bearing layer 25, so that there are gap areas between the two ends of the inner sleeve layer 18 and the edges of the overlapping structure inner sleeve bearing layer 25 on the same side. In this embodiment, the sizes of the gap areas between the two ends of the inner sleeve layer 18 and the edges of the overlapping structure inner sleeve bearing layer 25 on the same side are the same. At the same time, a concave layer 4 is provided at the gap area, and the outer shape of the concave layer 4 is the same as the outer shape of the gap formed between the inner sleeve layer 18 and the overlapping structure inner sleeve bearing layer 25. The provided concave layer 4 is used to block the gap formed between the inner sleeve layer 18 and the overlapping structure inner sleeve bearing layer 25, that is, the concave layer 4 is provided at both ends of the gap along the direction of the connection tunnel. By setting the concave layer 4, on the one hand, the gap is blocked, so that the gap forms a closed space, thereby avoiding interference from external factors to the internal radar detector 23. On the other hand, it is used to make the arched space formed at both ends of the overlapping structure inner sleeve bearing layer 25 the same as the arched space formed by the inner sleeve layer 18 in the middle position.

[0057] The connection passage also needs to serve important functions such as an escape passage and a vehicle transfer passage. The internal separation and guiding settings in the connection passage are particularly important, which can effectively avoid problems such as trampling and crowding during congestion.

[0058] Refer to Figure 5-6 , a through hole is opened at the top of the inner concave layer 4 near the edge of the connecting tunnel 3. Both the top and bottom of the overlapping structure inner sleeve bearing layer 25 and the through hole in the same vertical direction are provided with instrument slots 5. At the same time, a motor 6 is arranged in the instrument slot 5, and the motor 6 in the top instrument slot 5 and the motor 6 in the bottom instrument slot 5 in the same vertical direction are fixedly connected by a connecting column 7. In this way, the rotation of the connecting column 7 is driven by two groups of motors together.

[0059] Refer to Figure 7-8 , a rotatable internal blocking door 10 is arranged on the connecting column 7, and universal wheels 9 are symmetrically arranged at the bottom ends on both sides of the rotatable internal blocking door 10. At the same time, an annular guiding slot 8 is arranged at the bottom end of the overlapping structure inner sleeve bearing layer 25, so that the universal wheels 9 are nested in the annular guiding slot 8. Through the above settings, during the process of the motor 6 driving the rotatable internal blocking door 10 to rotate through the connecting column 7, the universal wheels 9 also operate along the annular guiding slot 8, so that the size of the rotatable internal blocking door 10 can be set to be the same as the size of the arched space formed by the inner concave layer 4, and finally when the rotatable internal blocking door 10 does not rotate, the connection passage is in a closed state.

[0060] Among them, the width of the gap area or the width of the inner concave layer 4 can be adjusted, only need to ensure that there is enough space to install the instrument slots 5 and the motor 6, and at the same time ensure that the arc-shaped chain track 19 can operate between the two rotatable internal blocking doors 10 along the two electric guide rails 30.

[0061] Refer to Figure 8 , a first slot frame 11 and a second slot frame 15 are respectively opened on both sides of the rotatable internal blocking door 10 at the same horizontal position.

[0062] Refer to Figure 9 , a horizontal display rack strip 12 is arranged in the first slot frame 11. One end of the display rack strip 12 is fixedly connected to the rotatable internal blocking door 10, and the other end of the display rack strip 12 is fixedly connected to a clamping column 13. At the same time, limiting grooves 14 are opened on both the upper and lower sides of the clamping column 13. In this embodiment, the display rack strip 12 is an X-shaped display rack strip. In order to ensure that the display rack strip 12 has enough length, the inside of the rotatable internal blocking door 10 at the same height as the first slot frame 11 can be hollowed out for storing the display rack strip 12.

[0063] Refer to Figure 10, on the upper and lower sides of the connection between the second slotted frame 15 and the rotatable internal door stopper 10, there are embedded electric push rods 16, and the electric push rods 16 are provided with limit bumps 17; among them, the moving directions of the push rods in the upper and lower electric push rods 16 are opposite, that is, the upper and lower electric push rods 16 drive the limit bumps 17 to move towards the middle position of the second slotted frame 15 at the same time.

[0064] In the actual application process, the motor 6 drives the rotatable internal door stoppers 10 at both ends of the overlapping structure inner sleeve load-bearing layer 25 to rotate, so that the first slotted frame 11 on one rotatable internal door stopper 10 and the second slotted frame 15 on the other rotatable internal door stopper 10 are in a relative state; the staff pulls the exhibition frame strip 12 and the engaging column 13 in the first slotted frame 11 on one rotatable internal door stopper 10, and nests the engaging column 13 in the second slotted frame 15 on the other rotatable internal door stopper 10. Through the limit groove 14 on the engaging column 13 and the limit bump 17 on the second slotted frame 15, the fixation between the rotatable internal door stoppers 10 at both ends is realized, and finally the separation and guidance inside the connection passage are realized.

[0065] Through the above settings, the flow direction of the personnel inside the connection passage can be separated, so that the congestion of the personnel inside the connection passage can be effectively avoided. At the same time, the smoothness of the pedestrian path can be improved, and the transfer time between the subway and the road can be reduced.

[0066] Although the specific implementation manners of the present invention are described above in conjunction with the accompanying drawings, it is not a limitation on the protection scope of the present invention. Those skilled in the art should understand that based on the technical solutions of the present invention, various modifications or deformations that can be made by those skilled in the art without creative labor are still within the protection scope of the present invention.
