Description

Technical Field

[0001] This utility model relates to the field of underground utility tunnel technology, specifically to an anti-settlement structure for underground integrated utility tunnels. Background Technology

[0002] Underground urban utility tunnels are tunnel spaces constructed beneath a city to integrate various engineering pipelines such as electricity, communications, gas, heating, and water supply and drainage. They are equipped with dedicated inspection ports, hoisting ports, and monitoring systems, and are subject to unified planning, design, construction, and management. They are vital infrastructure and lifelines for ensuring the operation of a city. Because underground utility tunnels are primarily located below the city surface, they may exist in various geological formations. When encountering silty soil, the instability of the silty soil and the potential for external pressure from above can cause localized subsidence, leading to displacement, cracking, or even breakage of the underground utility tunnel and / or its internal pipelines and facilities. Summary of the Invention

[0003] To address the aforementioned problems, the main objective of this invention is to provide an anti-settlement structure for underground integrated utility tunnels that can reduce the probability of tunnel settlement.

[0004] To achieve the main objective of this utility model, it provides an anti-settlement structure for an underground integrated utility tunnel, comprising a utility tunnel, a foundation, a support unit, and a shock-absorbing unit. The foundation extends along the extension direction of the utility tunnel and provides a receiving space. The utility tunnel is located within the receiving space. The support unit is supported on the lower outer side of the utility tunnel. The shock-absorbing unit includes two fixed side frames, two sets of buffer groups, and a support plate. The two fixed side frames are located on both sides of the utility tunnel and connected to it. One fixed side frame is installed on one side wall of the receiving space. The two sets of buffer groups correspond one-to-one with the two fixed side frames. The buffer groups are connected between the top wall of the receiving space and the corresponding fixed side frame. The support plate is connected between the two fixed side frames and covers the upper part of the utility tunnel.

[0005] As can be seen from the above, the support unit supports the utility tunnel, shares its weight, and prevents it from settling. The damping unit absorbs the pressure transmitted from the top of the foundation through the buffer group, preventing the pressure from being transmitted to the utility tunnel and causing it to settle. At the same time, the buffer group absorbs the vibration transmitted from the top of the foundation, preventing the vibration from affecting the utility tunnel and causing it to settle. In addition, through the design of the damping unit, when the buffer group is subjected to pressure transmitted from the top of the foundation, the pressure can be decomposed and transmitted to the fixed side frame, thereby making the fixed side frame fit more closely and firmly to the foundation. Furthermore, placing the support plate on the upper part of the utility tunnel protects it and prevents the top of the foundation from putting pressure on the utility tunnel, which could cause it to crack or be damaged. And fixing the utility tunnel to the foundation through the fixed side frame allows the utility tunnel to settle synchronously when the foundation settles, preventing the utility tunnel from being misaligned, cracked, or even broken relative to the foundation, thus better protecting the utility tunnel.

[0006] A preferred embodiment is that the damping unit also includes a cushioning layer, which is placed between the support plate and the pipe gallery.

[0007] As can be seen from the above, the buffer layer can absorb energy and vibrations transmitted from the top of the foundation, preventing these vibrations from being transmitted to the utility tunnel and causing damage to the tunnel and its facilities. In addition, it can buffer when the support plate is dented or deformed, preventing hard compression of the utility tunnel due to the dented deformation of the support plate, thereby reducing the probability of damage and cracking of the utility tunnel.

[0008] A further option is to make the cushioning layer from engineering plastics or rubber.

[0009] As can be seen from the above, this design enables the cushioning layer to have excellent elasticity, corrosion resistance and wear resistance, and makes the processing and molding of the cushioning layer more convenient.

[0010] Another preferred embodiment is that the side wall of the fixed side frame facing the receiving space is provided with an anchor bolt, which is inserted into the foundation.

[0011] As can be seen from the above, the anchor bolts can make the fixed side frame more firmly fixed to the foundation.

[0012] A further embodiment is that the fixed side frame has a first fixed part, a first support part, a second support part, and a second fixed part distributed in the height direction of the foundation. The first support part is connected between the second support part and the first fixed part, and the second support part is connected between the first support part and the second fixed part. The first support part and the second support part are distributed in a bent shape, and the included angle between the first support part and the second support part is an obtuse angle. Both the first fixed part and the second fixed part are provided with anchor bolts. The support plate is connected at the junction of the first support part and the second support part, and the pipe gallery is connected to the second fixed part.

[0013] As can be seen from the above, the relative position design of the first support and the second support allows the force to be distributed to the foundation through the cooperative structure of the first and second support when the support plate is under stress, thereby strengthening the reliability of the connection between the fixed side frame and the foundation.

[0014] A further proposed solution is that the buffer assembly includes a fixed seat and a buffer component. The fixed seat is installed on the top wall of the accommodating space, and the buffer component includes a first connecting seat, a second connecting seat, a compression spring, and a telescopic rod. The first connecting seat is hinged to the fixed seat, and the second connecting seat is hinged to the first fixed part. The compression spring and the telescopic rod are both connected between the first connecting seat and the second connecting seat, and the compression spring is sleeved on the telescopic rod.

[0015] As can be seen from the above, the compression spring can absorb the pressure and / or vibration transmitted from the top of the foundation, preventing the pressure and / or vibration from being transmitted to the pipe gallery and affecting it. The telescopic rod can support the compression spring, preventing it from bending and deforming under stress, thus ensuring the spring's buffering and energy absorption effect. The setting of the fixed seat, the first connecting seat and the second connecting seat can improve the absorption effect of the buffer group on the pressure and / or vibration transmitted from the top of the foundation.

[0016] A further proposed solution is to have a cross-section of the utility tunnel in the shape of a racetrack or a circle, with an arc-shaped support plate whose curvature is the same as that of the top of the utility tunnel; the top of the arc-shaped plate contacts the top wall of the accommodating space.

[0017] As can be seen from the above, this design helps to distribute pressure, increase structural stability, and thus better prevent the pipe gallery from settling.

[0018] A further proposed solution is that the second fixing part has a sleeve part on the side facing the pipe gallery, and the sleeve part has a threaded hole; the pipe gallery is connected to the threaded hole through a connecting assembly. When the cross-section of the pipe gallery is racetrack-shaped, the straight part of the racetrack shape is connected to the connecting assembly; the connecting assembly is a bolt, the bolt shank passes through the pipe gallery and is threadedly connected to the threaded hole, and the bolt nut contacts the inner wall of the pipe gallery; or the connecting assembly includes a stud and a nut, the stud passes through the pipe gallery and is threadedly connected to the threaded hole, and the nut is threadedly connected to the stud and contacts the inner wall of the pipe gallery.

[0019] As can be seen from the above, this design makes the connection between the pipe gallery and the fixed side frame more convenient and easier to operate.

[0020] A further proposed solution is to have two support units, located on opposite sides of the utility tunnel. Each support unit includes a support base plate and diagonal bracing. The diagonal bracing connects the utility tunnel and the support base plate. On the cross-section of the utility tunnel, the projections of the diagonal bracing of the two support units are roughly distributed in a figure-eight shape.

[0021] As can be seen from the above, this design helps to improve the pressure-bearing capacity of the support unit, so as to better support the pipeline and prevent the pipeline from sinking; in particular, the bottom plate helps to improve the support unit's support capacity for the pipeline, especially when the pipeline is in soft soil such as silt. The bottom plate can make the load of the pipeline more evenly distributed to the silt, thereby improving the load-bearing capacity of the support unit.

[0022] A further proposed solution is to align the bottom surface of the supporting base plate with the lowest point of the utility tunnel.

[0023] As can be seen from the above, this design enables the utility tunnel to work in conjunction with the supporting base plate to further support itself and improve its anti-settlement effect. Attached Figure Description

[0029] Example of an anti-settlement structure for underground utility tunnels

[0030] Reference Figure 1 and Figure 2 The underground integrated utility tunnel anti-settlement structure 100 includes a utility tunnel 11, a foundation 2, a vibration damping unit 3, and a support unit 4. The foundation 2 has a receiving space 21, which extends along the extension direction of the utility tunnel 11, and the utility tunnel 11 is located within the receiving space 21.

[0031] Combination Figure 3 and Figure 4 The damping unit 3 includes two fixed side frames 31, two sets of buffer groups 32, a support plate 33, and a buffer pad 34. The two fixed side frames 31 are located on both sides of the pipe gallery 11, such that one fixed side frame 31 is installed on one side wall 211 of the receiving space 21, and the pipe gallery 11 is connected to the two fixed side frames 31.

[0032] The fixed side frame 31 has a first fixing part 311, a first support part 312, a second support part 313, and a second fixing part 314, wherein the first fixing part 311, the first support part 312, the second support part 313, and the second fixing part 314 are distributed sequentially in the height direction of the foundation 2. It is understood that the first support part 312 connects the first fixing part 311 and the second support part 313, and the second support part 313 connects the first support part 312 and the second fixing part 314. In this embodiment, the first fixing part 311, the first support part 312, the second support part 313, and the second fixing part 314 are all generally rod-shaped; as other optional solutions, in some embodiments, the first fixing part 311, the first support part 312, the second support part 313, and the second fixing part 314 may all be plate-shaped; similarly, as other optional solutions, in some embodiments, the first fixing part 311 and the second fixing part 314 may be plate-shaped, while the first support part 312 and the second support part 313 may be generally rod-shaped. The first fixing part 311 and the second fixing part 314 are used for connection of the foundation 2; the first supporting part 312 and the second supporting part 313 are distributed in a bent shape, so that the included angle α between the first supporting part 312 and the second supporting part 313 is an obtuse angle.

[0033] Furthermore, the fixed side frame 31 has an anchor bolt portion 315 on the side wall 211 facing the accommodating space 21. When the fixed side frame 31 is fixed to the foundation 2, the anchor bolt portion 315 is inserted into the foundation 2, which allows the fixed side frame 31 to be more firmly fixed to the foundation 2. Preferably, both the first fixing part 311 and the second fixing part 314 are provided with anchor bolt portions 315.

[0034] The support plate 33 is connected between the two fixed side frames 31 and covers the upper part of the pipe gallery 11. Placing the support plate 33 on the upper part of the pipe gallery 11 protects the pipe gallery 11 and prevents the top of the foundation 2 from putting pressure on the pipe gallery 11, which could cause cracking or damage to the pipe gallery 11. In this embodiment, the support plate 33 is connected at the junction of the first support part 312 and the second support part 313. With the relative positional design of the first support part 312 and the second support part 313, when the support plate 33 is under force, the force can be distributed to the side wall 211 of the accommodating space 21 through the cooperation structure of the first support part 312 and the second support part 313, thereby strengthening the reliability of the connection between the fixed side frame 31 and the foundation 2.

[0035] Since the second fixing part 314 is connected to the foundation 2 and located below the junction of the first support part 312 and the second support part 313, in order to optimize the connection structure between the pipe gallery 11 and the fixed side frame 31 and the stress on the fixed side frame 31, the pipe gallery 11 is connected to the second fixing part 314. This allows the pipe gallery 11 to be fixed to the foundation 2 under the action of the fixed side frame 31. As a result, when the foundation 2 settles, the foundation 2 can drive the pipe gallery 11 to settle synchronously, thereby avoiding and preventing the pipe gallery 11 from being misaligned, cracked or even broken relative to the foundation 2, so as to better protect the pipe gallery 11.

[0036] In this embodiment, the cross-section of the pipe gallery 11 is racetrack shaped, and the arc-shaped portions on both sides of the racetrack shaped pipe gallery 11 are distributed along the height direction of the foundation 2; the support plate 33 is an arc plate, and the curvature of the arc plate is the same as the curvature of the top of the pipe gallery 11.

[0037] Since the top of the pipe gallery 11 and the support plate 33 are both arc-shaped structures, when the support plate 33 and the top of the pipe gallery 11 are subjected to pressure, the pressure from above can be transmitted to the fixed side frames 31 on both sides through their own shape, thereby reducing local pressure and effectively preventing the top of the pipe gallery 11 from being damaged due to excessive local pressure, such as dents or cracks. Furthermore, the arc-shaped structure has unique advantages in resisting lateral forces. For example, the arc-shaped top of the underground utility tunnel 11 and the support plate 33 can generate a certain resistance by utilizing their own shape to resist the lateral forces that the underground utility tunnel may encounter (such as seismic horizontal forces, soil lateral pressure, etc.). It can be understood that when subjected to lateral forces, the arc-shaped structure will generate a restoring force in the opposite direction, similar to a bent spring, so that it can better maintain its original position and reduce the possibility of displacement and deformation. It can be seen that the arc-shaped design of the top of the utility tunnel 11 and the support plate 33 can provide stable support in both vertical and horizontal directions, so that the entire utility tunnel 11 and support plate 33 system can maintain balance under various complex stress conditions.

[0038] In some embodiments, the cross-section of the pipe gallery 11 may also be circular.

[0039] In some embodiments, the top of the arc-shaped plate (i.e., the support plate 33) contacts the top wall 212 of the accommodating space 21, so that the arc-shaped plate can support the foundation 2, improve the bearing capacity of the foundation 2, and prevent the foundation 2 from sinking.

[0040] Furthermore, a sleeve portion 3141 can be provided on the side of the second fixing portion 314 facing the pipe gallery 11, wherein the sleeve portion 3141 has a threaded hole 31411; the pipe gallery 11 is connected to the threaded hole 31411 through the connecting assembly 5 to fix the pipe gallery 11 to the fixed side frame 31. Wherein, when the cross-section of the pipe gallery 11 is racetrack-shaped, the straight part of the racetrack shape is connected to the connecting assembly 5.

[0041] In this embodiment, the connecting assembly 5 includes a stud 51 and a nut 52. When connecting the pipe gallery 11 and the sleeve portion 3141 using the stud 51 and nut 52, the stud 51 extends out of the pipe gallery 11 and is then threaded into the threaded hole 31411. Next, the nut 52 is threaded onto the stud 51 inside the pipe gallery 11, and the nut 52 contacts the inner wall of the pipe gallery 11. Alternatively, in some embodiments, the connecting assembly 5 may also use a bolt. When connecting the pipe gallery 11 and the sleeve portion 3141 using a bolt, the bolt shank extends out of the pipe gallery 11 and is then threaded into the threaded hole 31411 until the bolt nut contacts the inner wall of the pipe gallery 11. This design makes the connection between the pipe gallery 11 and the fixed side frame 31 more convenient and easier to operate.

[0042] A buffer layer 34 is placed between the support plate 33 and the pipe gallery 11. The buffer layer 34 absorbs energy, preventing vibrations transmitted from the top of the foundation 2 and thus avoiding damage to the pipe gallery 11 and its internal facilities. It also cushions the pipe gallery 11 when the support plate 33 deforms, preventing hard compression and reducing the likelihood of damage or cracking. Furthermore, the buffer layer 34 prevents direct hard contact and friction between the top of the pipe gallery 11 and the support plate 33. During long-term use, especially when the pipe gallery 11 is subjected to external pressure or vibration, without the buffer layer 34, relative movement could occur between the top of the pipe gallery 11 and the support plate 33, leading to surface wear on the top of the pipe gallery 11. Moreover, the buffer layer 34 ensures a more even distribution of pressure on the top of the pipe gallery 11.

[0043] In this embodiment, the buffer layer 34 is made of engineering plastic, which may be polyamide, polycarbonate, polyoxymethylene, or polyphenylene ether, etc. Of course, as other optional solutions, in some embodiments, the buffer layer 34 is also made of rubber. By selecting the material of the buffer layer 34, it achieves excellent elasticity, enabling it to adaptively adjust its deformation according to the pressure when subjected to external forces, thereby effectively buffering the impact force when the utility tunnel 11 is subjected to vibration or pressure. Furthermore, engineering plastics and rubber generally have good resistance to many chemicals. In the environment of underground utility tunnels, there may be corrosive factors such as groundwater and chemicals in the soil. For example, groundwater may contain sulfates, chloride ions, etc., which may corrode materials such as metals. Engineering plastics and rubber materials... The material itself has the characteristics of resisting chemical corrosion, and can maintain the stability of its physical and chemical properties in such a complex chemical environment, thereby ensuring the service life and performance of the buffer pad 34. In addition, both engineering plastics and rubber have a certain degree of wear resistance. During the long-term use of the pipe gallery 11, the buffer pad 34 may generate friction due to the small displacement between the pipe gallery 11 and the support plate 33. The excellent wear resistance can enable the buffer pad 34 to maintain its integrity during repeated friction, so as to ensure that the buffer pad 34 can still effectively play its buffering and protective role after long-term use.

[0044] Two sets of buffer groups 32 correspond one-to-one with two fixed side frames 31. The buffer groups 32 are connected between the top wall 212 of the accommodating space 21 and the corresponding fixed side frame 31. The damping unit 3 can absorb the pressure transmitted from the top of the foundation 2 through the buffer groups 32, so as to prevent the pressure from being transmitted to the pipe gallery 11 and causing the pipe gallery 11 to sink. At the same time, the buffer groups 32 can absorb the vibration transmitted from the top of the foundation 2, so as to avoid the vibration affecting the pipe gallery 11 and causing the pipe gallery 11 to sink. In addition, through the design of the damping unit 3, when the buffer group 32 is subjected to the pressure transmitted from the top of the foundation 2, the pressure can be decomposed and transmitted to the fixed side frame 31, thereby making the fixed side frame 31 fit more closely and firmly on the foundation 2.

[0045] In this embodiment, the buffer assembly 32 includes a fixed seat 321 and a buffer member 322. The fixed seat 321 is installed on the top wall 212 of the accommodating space 21. The buffer member 322 includes a first connecting seat 3221, a second connecting seat 3222, a compression spring 3223, and a telescopic rod 3224. The first connecting seat 3221 is hinged to the fixed seat 321, and the second connecting seat 3222 is hinged to the first fixing part 311 of the fixed side frame 31. The compression spring 3223 and the telescopic rod 3224 are both connected between the first connecting seat 3221 and the second connecting seat 3222, and the compression spring 3223 is sleeved on the telescopic rod 3224.

[0046] It is understood that the number of buffer elements 322 in the buffer group 32 can be multiple. When the number of buffer elements 322 is multiple, the multiple buffer elements 322 are distributed along the extension direction of the pipe gallery 11. In some embodiments, the fixing seat 321 is a single individual, that is, the number of fixing seats 321 is equal to the number of buffer elements 322, and multiple fixing seats 321 correspond one-to-one with multiple buffer elements 322; while in some embodiments, the fixing seat 321 can be in the form of a strip or a plate. In this case, the number of fixing seats 321 can be one or more, and each fixing seat 321 can be connected to two or more buffer elements 322.

[0047] The design of the buffer component 322 enables the compression spring 3223 to absorb the pressure and / or vibration transmitted to the top of the foundation 2, preventing the pressure and / or vibration from being transmitted to the pipe gallery 11 and affecting it. The telescopic rod 3224 supports the compression spring 3223, preventing it from bending and deforming due to excessive force and losing stability, thus ensuring the spring's buffering and energy absorption effect. The setting of the fixed seat 321, the first connecting seat 3221, and the second connecting seat 3222 can enhance the absorption effect of the buffer group 32 on the pressure and / or vibration transmitted to the top of the foundation 2.

[0048] Support unit 4 is located on the lower outer side of the utility tunnel 11. Support unit 4 supports the utility tunnel 11, shares its weight, and prevents it from sinking. In this embodiment, there are two support units 4, located on opposite sides of the utility tunnel 11. Support unit 4 includes a support base plate 41 and diagonal braces 42, which connect the utility tunnel 11 and the support base plate 41. On the cross-section of the utility tunnel 11, the projections of the diagonal braces 42 of the two support units 4 are approximately in a figure-eight shape. This design helps improve the load-bearing capacity of the support unit 4, better supporting the utility tunnel 11 and preventing it from sinking. Furthermore, the base plate helps enhance the support capacity of the support unit 4 for the utility tunnel 11, especially when the utility tunnel 11 is in soft soil such as silt. The base plate allows the load of the utility tunnel 11 to be more evenly distributed to the silt, thereby improving the load-bearing capacity of the support unit 4.

[0049] In some embodiments, the bottom surface of the support base plate 41 is flush with the lowest point of the pipe gallery 11, so that the pipe gallery 11 can cooperate with the support base plate 41 to further support itself and improve the anti-settlement effect.

[0050] In summary, the design of the anti-settlement structure 100 for the underground utility tunnel can reduce the probability of settlement of the tunnel 11.

[0051] Finally, it should be emphasized that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. For those skilled in the art, the present utility model can have various changes and modifications. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
