Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of underground pipe galleries, in particular to an underground comprehensive pipe gallery for urban planning and design. BACKGROUND

[0002] In urban planning and design, the underground comprehensive pipe gallery, as a public tunnel for centrally laying municipal pipelines such as power, communication, water supply and drainage, can effectively avoid repeated excavation of the road surface and improve the utilization rate of urban underground space. The existing underground pipe gallery is mostly of a prefabricated segment splicing structure, and the segments are connected through flanges, bolts or socket joints.

[0003] When the ground foundation undergoes uneven settlement, the connection part is prone to become a stress concentration area due to the difference in stiffness between the splicing joint and the adjacent pipe gallery segment, resulting in concrete cracking, joint leakage and even structural failure. In particular, in soft soil areas or earthquake-prone areas, the ground settlement is more significant, further increasing the risk of joint damage. Therefore, the rigid connection mode of the traditional pipe gallery is difficult to adapt to the ground deformation, the repair cost is high, and it may affect the normal operation of the pipelines in the pipe gallery. SUMMARY

[0004] In order to improve the adaptability of the underground pipe gallery to the ground settlement, the present application provides an underground comprehensive pipe gallery for urban planning and design.

[0005] The present application provides an underground comprehensive pipe gallery for urban planning and design, which adopts the following technical solution: An underground comprehensive pipe gallery for urban planning and design, comprising: prefabricated segments, a plurality of the prefabricated segments being spliced in sequence; each of the prefabricated segments comprising an outer member formed with a mounting cavity and having a sliding groove provided at one end in the vertical direction and a sliding part provided at the other end; an inner member located in the mounting cavity and formed with a storage cavity for placing pipelines, and a cavity layer being provided between the inner member and the outer member in the circumferential direction of the inner member; a support member vertically supported between the inner member and the outer member on both sides in the vertical direction and capable of vertical height adjustment; and a flexible deformation member provided at the end of the inner member; Among the two adjacent prefabricated segments, the sliding part of one outer member slides up and down in the sliding groove of the other outer member, and the two inner members are connected through the flexible deformation member.

[0006] By adopting the technical scheme, through the splicing of prefabricated segments, the cooperation of the sliding grooves and sliding portions of the outer members, and the connection between the flexible deformation members of the inner members, the underground comprehensive pipe gallery can adapt to uneven settlement of the foundation, reduce stress concentration, and through the height adjustment of the support members, the height of the inner members can be re-adjusted after the settlement of the foundation. At the same time, the cavity layer forms a buffer between the inner members and the outer members, assisting in heat dissipation or heat insulation.

[0007] Optionally, the support member comprises a first abutting seat, a second abutting seat and a stop nut. The first abutting seat is abutted with the outer wall of the inner member, the second abutting seat is abutted with the inner wall of the outer member, and the first abutting seat has a threaded portion vertically sliding in the second abutting seat, the stop nut is threadedly sleeved on the threaded portion and abutted with the second abutting seat to limit the relative sliding of the first abutting seat and the second abutting seat in the direction of approaching each other.

[0008] By adopting the technical scheme, the threaded portion of the first abutting seat of the support member slides in the second abutting seat, and the stop nut can lock the vertical height of the support member, so that the height of the inner member can be accurately adjusted. When the foundation settlement causes the inner member to tilt, the adjacent inner members can be leveled by adjusting the support member, so that the pipeline slope meets the requirements, which supplements the defect that the traditional pipe gallery is difficult to repair after settlement, provides an adjustable support mechanism, and reduces the maintenance cost.

[0009] Optionally, the support member further comprises an elastic portion, which is arranged between the first abutting seat and the second abutting seat, and gives the first abutting seat and the second abutting seat a tendency to move away from each other.

[0010] By adopting the technical scheme, the setting of the elastic portion enables the support member to have a buffering capacity to absorb part of the impact force generated by the foundation settlement or external vibration. The pre-tightening force of the elastic portion keeps the support member in a stable state, and the support failure caused by loosening is less likely to occur.

[0011] Optionally, the first abutting seat has a limiting portion, and the outer wall of the inner member has a limiting groove for the limiting portion to enter.

[0012] By adopting the technical scheme, the cooperation of the limiting portion and the limiting groove prevents the first abutting seat from deviating relative to the inner member in the horizontal direction, improving the position stability of the support member.

[0014] The telescopic rod hinged between the outer side wall of the inner layer component and the inner side wall of the outer layer component can be telescoped with the height adjustment of the inner layer component, and simultaneously provides lateral support, enhances the anti-tilting ability of the inner layer component, prevents the inner layer component from deviating during vertical adjustment, assists in supporting the inner layer component, and improves the stability of the inner layer component in three-dimensional space. Meanwhile, the inner layer component is limited relative to the outer layer component, and the movement of the inner layer component relative to the outer layer component along the length direction is limited.

The inner layer component is provided with an adjusting mechanism for adjusting the angle of the first cover plate relative to the inner layer component, so that the first cover plate is switched between the corresponding open state and closed state thereof. The open state is that the free end of the first cover plate is away from the component wall of the inner layer component, so that the ventilation hole is opened. The closed state is that the free end of the first cover plate is attached to the component wall of the outer layer component, so that the ventilation hole is shielded and closed.

[0016] By adopting the above technical scheme, the ventilation hole provided on the inner layer component communicates the storage cavity and the cavity layer, and when opened, can discharge the heat generated by the air convection pipeline. The first cover plate is switched between the open state and the closed state through the adjusting mechanism, so that the ventilation amount can be controlled as needed. In summer, the ventilation hole is opened for heat dissipation, in winter, the ventilation hole is closed for heat preservation, or in case of fire, the ventilation hole is closed to block the smoke.

[0017] Optionally, the ventilation hole and the first cover plate are arranged on opposite sides of the inner layer component, and the adjusting mechanism comprises a power telescopic source and a connecting rod. The power telescopic source is installed in the inner layer component, and the connecting rod is hinged to the telescopic end of the power telescopic source and the first cover plate at two ends respectively. The first cover plate is switched between the open state and the closed state by the extension and retraction of the telescopic end of the power telescopic source.

[0018] By adopting the above technical scheme, the mechanical linkage of the power telescopic source and the connecting rod realizes the quick opening and closing of the first cover plate, which is fast in response and easy to operate.

DETAILED DESCRIPTION

[0027] The following will be described in detail with reference to the accompanying drawings. Figure 1 to the accompanying drawings. Figure 9 The present application will be further described in detail.

[0028] Embodiment one:

[0029] The embodiment of the present application discloses an underground comprehensive pipe gallery for urban planning and design. Referring to Figure 1 The underground comprehensive pipe gallery for urban planning and design comprises a plurality of prefabricated segments 1, which are sequentially spliced to form a pipe gallery. Each prefabricated segment 1 comprises an outer member 2, an inner member 3, a support 4, and a flexible deformation part 5.

[0030] Referring to Figure 1 and Figure 2 The outer member 2 is in a square ring structure, and the inner cavity is an installation cavity 6, which penetrates through both ends of the outer member 2 along the length direction of the outer member 2. The end face of one end of the outer member 2 is provided with a vertical sliding groove 7, and the sliding part 8 is fixed to the end face of the other end. The sliding part 8 and the sliding groove 7 correspond to each other, and both the sliding part 8 and the sliding groove 7 are arranged on the side of the end face of the outer member 2. Meanwhile, the sliding part 8 is in a vertical long strip shape, the cross section of the sliding part 8 is in a dovetail shape with the width gradually increasing away from the outer member 2, and the shape of the sliding groove 7 is adapted to the sliding part 8. In this embodiment, the outer member 2 is made of concrete material.

[0031] With reference to Figure 1 and Figure 3 , the inner layer member 3 is in a square ring structure, and the inner cavity is a storage cavity 9 for installing a pipeline. The size of the inner layer member 3 is smaller than that of the outer layer member 2, the inner layer member 3 is installed in the installation cavity 6 of the outer layer member 2, and the opposite ends of the inner layer member 3 are close to the opposite ends of the outer layer member 2, and the length extension direction of the inner layer member 3 is smaller than that of the outer layer member 2. It should be noted that there is a gap between the inner layer member 3 and the outer layer member 2 along the circumferential direction of the inner layer member 3, so that the inner layer member 3 and the outer layer member 2 form a cavity layer 10 which is communicated along the circumferential direction of the inner layer member 3.

[0032] With reference to Figure 1 and Figure 4 , the support member 4 is installed between the inner layer member 3 and the outer layer member 2 for supporting and installing the inner layer member 3. Specifically, the support member 4 is arranged between the outer bottom surface of the inner layer member 3 and the inner bottom surface of the outer layer member 2, and between the outer top surface of the inner layer member 3 and the inner top surface of the outer layer member 2. Each support member 4 comprises a first abutting seat 41, a second abutting seat 42, a stop nut 43 and an elastic part 44.

[0033] The first abutting seat 41 comprises a first abutting part 411, a threaded part 412 and a limiting part 413. The first abutting part 411 is in a flat plate shape and abuts to the surface of the inner layer member 3. The threaded part 412 is in a threaded column shape, and is fixed to the first abutting part 411 and extends vertically away from the inner layer member 3. The limiting part 413 is in a square block shape and is fixed to the first abutting part 411 towards the inner layer member 3 and is inserted into the inner layer member 3. The outer wall of the inner layer member 3 is provided with a limiting groove (not shown in the figure) for the insertion of the limiting part 413. The second abutting seat 42 comprises a second abutting part 421 and a sleeve part 422. The second abutting part 421 is in a flat plate shape and abuts to the surface of the outer layer member 2. The sleeve part 422 is fixed to the second abutting part 421 and extends vertically towards the inner layer member 3. At the same time, the end of the threaded part 412 away from the second abutting part 421 slides vertically in the sleeve part 422. The stop nut 43 is coaxially threaded on the threaded part 412 and abuts to the end of the sleeve part 422 away from the second abutting part 421. The elastic part 44 is a spring, which is located in the inner cavity of the sleeve part 422. The two ends of the elastic part 44 away from each other are connected to the sleeve part 422 and the threaded part 412 respectively. At the same time, the elastic part 44 is in a compressed state, so that the elastic force of the elastic part 44 gives the first abutting seat 41 and the second abutting seat 42 a tendency to move away from each other.

[0034] With reference to Figure 1 and Figure 3The flexible deformation member 5 is annular in shape and is adapted to the inner layer member 3. The flexible deformation member 5 is bolted to the end of the inner layer member 3, and the end of the flexible deformation member 5 and the end of the inner layer member 3 are provided with water-stopping rubber (not shown in the figure). In this embodiment, the flexible deformation member 5 is a metal corrugated compensator, and in other embodiments, the flexible deformation member 5 can also be a rubber compensator.

[0035] According to the above, the connection between the two adjacent prefabricated segments 1 is that the sliding part 8 of one of the two adjacent outer layer members 2 is inserted into the sliding groove 7 of the other outer layer member 2 in the vertical direction, so that the mounting cavities 6 of the two adjacent outer layer members 2 are connected and communicated, and the outer layer member 2 is fixed to the foundation by expansion bolts; the two adjacent inner layer members 3 are connected and communicated by the flexible deformation member 5.

[0036] When the foundation settles unevenly, the adjacent outer layer members 2 move relative to each other through the sliding part 8 and the sliding groove 7 to adapt to the foundation settlement, and the adjacent inner layer members 3 deform flexibly through the flexible deformation member 5 to adapt to the foundation settlement. When there is a pipeline in the inner layer member 3 that requires a slope, such as a gravity flow pipeline, the inner layer member 3 is supported by a jack, and the position of the stop nut 43 on the threaded portion 412 is adjusted to adjust the height of the inner layer member 3, so that the adjacent inner layer members 3 are flush. In addition, when the support member 4 is damaged or reaches the end of its service life, the support member 4 can be removed from between the inner layer member 3 and the outer layer member 2 and replaced with a new one by adjusting the height of the support member 4.

[0037] Referring to Figure 1 Further, the inner layer member 3 is hinged between the two outer side walls on the corresponding inner side walls of the outer layer member 2, and the telescopic rod 11 is threadedly sleeved on the end of the sleeve, abutting against the nut on the end of the sleeve, to limit the retraction of the telescopic rod 11, thereby supporting the side of the inner layer member 3. When adjusting the height of the inner layer member 3, the telescopic length of the telescopic rod 11 is adaptively adjusted.

[0038] Referring to Figure 1 and Figure 5 In addition, since the pipeline generates heat during use, in order to improve the ventilation and cooling effect in the inner layer member 3, a plurality of ventilation holes 12 are formed in the length direction of the inner layer member 3 on the two opposite sides of the inner layer member 3, and a first cover plate 13 is hinged to the inner side of the inner layer member 3, and a second cover plate 15 is hinged to the outer side of the inner layer member 3. The first cover plate 13 and the second cover plate 15 are both square plates. The hinged ends of the first cover plate 13 and the second cover plate 15 are both located at the top of the plate and above the ventilation holes 12. The first cover plate 13 and the second cover plate 15 have an open state and a closed state.

[0039] The open state is characterized in that the free ends of the first cover plate 13 and the second cover plate 15 are rotated in a direction away from each other to leave the component walls of the inner layer component 3, at this time, the first cover plate 13 and the second cover plate 15 are both away from the ventilation holes 12, the storage cavity 9 of the inner layer component 3 and the cavity layer 10 are communicated through the ventilation holes 12, so that the storage cavity 9 of the inner layer component 3 can exchange heat with the cavity layer 10, so as to reduce the heat in the inner layer component 3. The closed state is characterized in that the free ends of the first cover plate 13 and the second cover plate 15 are rotated in a direction close to each other to abut and fit on the inner and outer component walls of the inner layer component 3 respectively, at this time, the first cover plate 13 and the second cover plate 15 shield the ventilation holes 12 on the same side, so as to close the ventilation holes 12 when the storage cavity 9 and the cavity layer 10 do not need to exchange heat.

[0040] With reference to Figure 5 and Figure 6 In order to realize the rotation of the first cover plate 13 and the second cover plate 15, the adjusting mechanism 14 for adjusting the rotation state of the first cover plate 13 is installed in the inner layer component 3, and the synchronization mechanism 16 for driving the first cover plate 13 and the second cover plate 15 to adjust synchronously is provided between the first cover plate 13 and the second cover plate 15.

[0041] With reference to Figure 5 Specifically, the adjusting mechanism 14 includes a power telescopic source 141 and a connecting rod 142. The power telescopic source 141 is an electric telescopic rod 11 corresponding to the first cover plate 13, the base of the power telescopic source 141 is fixedly installed on the inner top surface of the inner layer component 3, and the telescopic end of the power telescopic source 141 telescopes in the horizontal direction. The end of one end of the connecting rod 142 is hingedly connected to the telescopic end of the power telescopic source 141 through a pin shaft, the opposite end of the connecting rod 142 is hingedly connected to the side of the first cover plate 13 away from the second cover plate 15, and the hinge axes of the two ends of the connecting rod 142 are both parallel to the hinge axis between the first cover plate 13 and the inner layer component 3.

[0042] When the telescopic rod 11 of the power telescopic source 141 is retracted, the first cover plate 13 is in the open state, and when the telescopic rod 11 of the power telescopic source 141 is extended, the first cover plate 13 is driven by the connecting rod 142 to move to the closed state.

[0043] With reference to Figure 6 and Figure 7, the synchronous mechanism 16 comprises a first sliding seat 161, a second sliding seat 162, a synchronous rack 163 and a synchronous gear 164. The first sliding seat 161 slides on the side of the first cover plate 13 facing the second cover plate 15 along the height direction of the first cover plate 13, and the first sliding seat 161 is in T shape. The first cover plate 13 is provided with a first sliding groove corresponding to the shape of the first sliding seat 161 for the sliding of the first sliding seat 161, so as to limit the disengagement of the first sliding seat 161 when sliding on the first cover plate 13. Similarly, the second sliding seat 162 slides on the side of the second cover plate 15 facing the first cover plate 13 along the height direction of the second cover plate 15, and the second sliding seat 162 is in T shape. The second cover plate 15 is provided with a second sliding groove for the sliding of the second sliding seat 162.

[0044] The installation box 18 for installing the synchronous rack 163 and the synchronous gear 164 is pre-buried on the side wall of the inner layer member 3, and the opposite sides of the installation box 18 are flush with the opposite sides of the member wall of the inner layer member 3. The synchronous rack 163 has two, and the two synchronous racks 163 slide in the installation box 18 in parallel and along the horizontal and parallel direction. The tooth surfaces of the two synchronous racks 163 are opposite to each other, and the sliding directions of the two synchronous racks 163 are perpendicular to the extension direction of the hinge axis of the first cover plate 13, and the ends of the two synchronous racks 163 away from each other are respectively hinged to the first sliding seat 161 and the second sliding seat 162. The synchronous gear 164 is rotationally connected in the installation box 18, and the synchronous gear 164 is located between the two synchronous racks 163, and the opposite sides of the synchronous gear 164 are respectively engaged with the tooth surfaces of the two synchronous racks 163. Therefore, when the adjusting mechanism 14 drives the first cover plate 13 to move, the first cover plate 13 drives the second cover plate 15 to move synchronously through the engagement of the synchronous rack 163 and the synchronous gear 164, and when the first cover plate 13 and the second cover plate 15 are both in the closed state, the synchronous rack 163 is completely accommodated in the installation box 18.

[0045] Referring to Figure 7 In order to improve the stability of the movement of the synchronous rack 163, a guide portion 19 is fixed to the side of the synchronous rack 163 away from the tooth surface and slides in the installation box 18. The installation box 18 is provided with a guide groove 20 for the sliding of the guide portion 19 along the sliding direction of the synchronous rack 163, and the cross section of the guide portion 19 is in dovetail shape.

[0046] Further, in other embodiments, a smoke sensor (not shown in the figure) is installed in the inner layer member 3. When the smoke sensor senses smoke when the pipeline in the inner layer member 3 catches fire, it transmits a signal to the controller, and the controller controls the power source 141 to extend the telescopic end, so that the first cover plate 13 and the second cover plate 15 close the ventilation hole 12. In addition, a sprinkler controlled by the smoke sensor can also be installed in the inner layer member 3 to provide precipitation to the fire.

[0047] The implementation principle of the underground comprehensive pipe gallery for urban planning design in the embodiment of the application is as follows: when uneven settlement occurs in the local foundation, the adjacent outer member 2 is adapted to the settlement deformation through the relative vertical sliding of the sliding part 8 and the sliding groove 7, so as to reduce the stress concentration phenomenon. The screw adjusting function of the support 4 allows the height of the inner member 3 to be adjusted to meet the pipeline slope requirement. The ventilation hole 12 can be opened and closed according to the segment requirement.

[0048] Embodiment two:

[0049] The difference between the embodiment of the application and embodiment one is that the underground comprehensive pipe gallery for urban planning design further comprises a spraying device 17.

[0050] With reference to Figure 8 and Figure 9 , the spraying device 17 is installed on the inner side wall of the outer member 2, and the spraying device 17 radiates towards the second cover plate 15 and the outer side wall of the inner member 3. Specifically, the spraying device 17 comprises a main pipe 171, a branch pipe 172, an electromagnetic valve 173, a segment pipe 174 and a spraying head 175. The main pipe 171 is installed on the inner wall of the outer member 2 and spans multiple prefabricated segments 1, and the main pipe 171 is a flexible pipe to adapt to the settlement of the prefabricated segment 1. The main pipe 171 is communicated with one branch pipe 172 at each prefabricated segment 1, and the electromagnetic valve 173 is installed on the branch pipe 172. The segment pipe 174 corresponds to the prefabricated segment 1 one by one and is installed on the inner wall of the outer member 2 of the corresponding prefabricated segment 1, and the segment pipe 174 is closed at two ends away from each other, and the end of the branch pipe 172 away from the main pipe 171 is communicated to the segment pipe 174. The spraying head 175 is installed and communicated on the segment pipe 174, and the spraying head 175 radiates to the outer side wall of the inner member 3 towards the second cover plate 15, and the spraying head 175 is provided with multiple along the length direction of the segment pipe 174.

[0051] The branch pipe 172 is opened and closed by the electromagnetic valve 173 to be able to spray a specified segment for further cooling, and the second cover plate 15 blocks the water mist to reduce the influence of the water mist entering the inner member 3 on the operation of the pipeline.

[0052] Embodiment three:

[0053] The difference between the embodiment of the application and embodiment one and embodiment two is that the outer member 2 in the embodiment is made of steel.

[0054] Compared with concrete, steel can exchange heat with the surrounding soil better, so that when the storage cavity 9 and the cavity layer 10 exchange heat, the steel exchanges heat between the cavity layer 10 and the surrounding soil, so as to improve the heat dissipation effect of the storage cavity 9.

[0055] The above are all preferred embodiments of the present application, and do not limit the protection scope of the present application, so that: all equivalent changes made according to the structure, shape, principle of the present application should be covered in the protection scope of the present application.
