Description

Technical Field

[0001] The present invention relates to the technical field of civil engineering, and in particular to a high-toughness integrated pipe gallery in a strong earthquake zone and a manufacturing method thereof. Background Art

[0002] An integrated utility corridor is a tunnel constructed underground within a city to centrally lay various municipal pipelines, including water supply and drainage, gas, electricity, and telecommunications. Urban integrated utility corridors offer enormous potential and advantages in building sponge cities, rationally utilizing underground space to expand public areas, improving a city's comprehensive carrying capacity and operational capabilities, developing new urbanization initiatives, and implementing smart management. They also eliminate the need for separate, irregular excavation of specialized pipelines, minimizing the impact on road traffic and the surrounding environment, and completely resolving issues associated with traditional pipeline layout methods, such as "road zippers" and "aerial spider webs."

[0003] Earthquakes are natural phenomena caused by the compression and collision of Earth's plates. Severe earthquakes can cause secondary disasters such as building collapses, severely disrupting normal human activities. Earthquakes can be classified as both horizontal and vertical, but they often simultaneously affect structural deformation. This is particularly true for prefabricated pipeline corridors, which can cause displacement, horizontal deformation, vertical deformation, and distortion. Failure to implement effective earthquake mitigation measures can lead to significant property losses.

[0004] Traditional utility corridors are mostly cast-in-place concrete. This method is slow to construct, inefficient, and significantly impacts the surrounding environment. Prefabricated utility corridors currently include segmental, block, and composite types. These prefabricated structures significantly improve construction efficiency. However, compared to cast-in-place structures, prefabricated structures inevitably suffer from shortcomings such as poor integrity, rigidity, and seismic resistance. Furthermore, utility corridors are typically single-story, making earthquake damage difficult to use and irreparable, resulting in poor seismic performance.

[0005] There are some prefabricated, prefabricated utility corridors in the prior art. These prefabricated utility corridors typically connect segments via post-cast concrete strips or steel strands. However, a drawback of this type of prefabricated utility corridor is that when the foundation deforms unevenly along the length of the corridor due to factors such as consolidation, earthquakes, and surrounding disturbances, the rigid structure of the corridor cannot adapt well to the uneven deformation, resulting in additional stress on the corridor structure and even cracks in the corridor's connecting sections, causing leakage. Summary of the Invention

[0006] The purpose of the present invention is to provide a high-toughness integrated pipeline corridor for strong earthquake areas and a manufacturing method thereof, so as to solve the problems existing in the prior art.

[0007] The technical solution adopted to achieve the purpose of the present invention is as follows: a high-toughness integrated pipeline corridor in a strong earthquake zone, including an inner segmented prefabricated integrated pipeline corridor, an outer prefabricated assembled enclosure structure and a universal rotating hinge support.

[0008] The inner segmented prefabricated integrated pipe corridor includes several adjacent pipe corridor segments I. The two ends of each pipe corridor segment I along its length are designated as the front and rear faces, respectively. The front and rear faces are configured with corresponding stepped edges. The front face is provided with a groove I for accommodating a waterstop. Each pipe corridor segment I is joined together using the stepped edges and then connected and compressed using steel strands to form a continuous pipe corridor.

[0009] The outer prefabricated assembled enclosure structure includes several sections of pipe gallery segments II arranged closely together. The two ends of the pipe gallery segment II along the length direction are respectively recorded as the front end face and the rear end face. The rear end face is provided with a groove on the rear end face of the side panel, and the front end face is provided with a groove on the front end face of the side panel corresponding to the groove on the rear end face of the side panel. Each pipe gallery segment II is spliced together section by section and connected and compressed by steel strands to form a continuous pipe gallery. A universal joint hinge is provided between adjacent pipe gallery segments II. The universal joint hinge includes a universal yoke fork at the front end of the side panel, a cross shaft, and a universal yoke fork at the rear end of the side panel, which are connected in sequence. The universal yoke fork at the front end of the side panel is embedded in the groove on the front end face of the side panel. The universal yoke fork at the rear end of the side panel is embedded in the groove on the rear end face of the side panel. Under the action of the universal joint hinge, adjacent pipe gallery segments II can slide vertically, laterally, and torsionally within a limited range.

[0010] The inner segmented prefabricated integrated pipe corridor is nested in the outer prefabricated assembled enclosure structure. A gap is left between the inner segmented prefabricated integrated pipe corridor and the outer prefabricated assembled enclosure structure as a deformation adjustment space. A universal hinge support is provided in the gap between the inner segmented prefabricated integrated pipe corridor and the outer prefabricated assembled enclosure structure. One end of the universal hinge support is fixedly connected to the outer prefabricated assembled enclosure structure, and the other end is against the inner segmented prefabricated integrated pipe corridor. The universal hinge support includes a retractable damper, a universal hinge point and a slidable damping layer. When an earthquake or foundation deformation occurs, the universal hinge support adaptively adjusts according to the deformation of the outer enclosure structure, thereby ensuring that no large dislocation, additional stress and deformation are generated between the segments of the inner segmented prefabricated integrated pipe corridor, thereby reducing the impact of the earthquake on the inner pipe corridor.

[0011] Furthermore, waterproof fillers and wedge-shaped rubber rings are provided between adjacent pipe gallery sections I. Waterproof fillers and wedge-shaped rubber rings are provided between adjacent pipe gallery sections II.

[0012] Furthermore, it also includes side panel buttresses, which are arranged outside the outer prefabricated assembled enclosure structure.

[0013] Furthermore, the water stop strip is a water-expanding water stop strip. The pipe gallery segment I and pipe gallery segment II are cast with ECC concrete.

[0014] Furthermore, the pipe gallery segment I includes two horizontally arranged transverse panels I and two vertically arranged side panels I. The two side panels I are connected between the two transverse panels I and are arranged opposite each other. The two transverse panels I and the two side panels I enclose the pipe gallery segment I. Both ends of the transverse panels I and the side panels I are provided with stepped edges. The transverse panels I and the side panels I are connected by a socket-and-spigot connection. The surface of the transverse panels I is provided with a socket groove I for the side panels I to insert. The socket groove I is provided with a waterstop and waterproof filler.

[0015] Furthermore, the pipe gallery segment II includes two horizontally arranged transverse plates II and two vertically arranged side plates II. The two side plates II are connected between the two transverse plates II and are arranged opposite to each other. The two transverse plates II and the two side plates II enclose the pipe gallery segment II. The front end surface of the transverse plate II is provided with a groove II for accommodating a waterstop. The transverse plate II and the side plates II are connected by a socket-type connection. The surface of the transverse plate II is provided with a socket groove II for inserting the side plates II. The socket groove II is provided with a waterstop and a waterproof filler.

[0016] Furthermore, the gap between the inner segmented prefabricated integrated pipeline corridor and the outer prefabricated assembled enclosure structure is filled with energy-absorbing flexible materials.

[0017] Furthermore, the length of each section of the pipe gallery segment I is a, and the length of each section of the pipe gallery segment II is b, wherein a>b.

[0018] Furthermore, a supporting steel plate is provided at one end of the universal hinge support. Anchor steel bars are welded to the surface of the supporting steel plate. The anchor steel bars are connected to the inner layer of the segmented prefabricated integrated pipe corridor.

[0019] The present invention also discloses a method for manufacturing a high-toughness integrated pipeline corridor in a strong earthquake zone, comprising the following steps:

[0020] 1) Prefabricate pipe gallery segment I and pipe gallery segment II and transport them to the construction site.

[0021] 2) Dig a trench on site for installing the pipeline corridor and pour a shock-absorbing cushion at the bottom of the trench.

[0022] 3) Place the horizontal plate II used as the bottom plate of N sections of the tunnel segment II on the cushion layer in turn, and splice the corresponding side plate II.

[0023] 4) Install the universal hinge support on the horizontal plate II used as the base plate according to the designed position.

[0024] 5) Assemble M-section pipeline corridor segment I.

[0025] 6) Fix the M-section tunnel segment I to the universal hinge support.

[0026] 7) Install horizontal plate II to serve as the top plate.

[0027] 8) Repeat steps 1) to 7) to proceed to the next pipe section.

[0028] The technical effects of the present invention are unquestionable:

[0029] A. The outer tunnel segments can directly move vertically, horizontally, and torsionally to adapt to foundation settlement deformation. Gaps are reserved between the inner and outer layers, and supports that can adapt to deformation are set. The deformation and rotation of the outer layer does not affect the inner layer;

[0030] B. The outer layer is made of high-ductility material and is easy to repair; the outer layer dissipates energy, reducing the damage to the inner layer caused by earthquake energy;

[0031] C. After a period of operation after construction and when the foundation settlement is stable, waterproof materials such as polymers can be injected into the pores between the inner and outer layers to make the pipeline corridor more stable during long-term use.

DETAILED DESCRIPTION

[0044] The present invention will be further described below with reference to the following examples, but it should not be understood that the scope of the present invention is limited to the following examples. Without departing from the above technical ideas of the present invention, various substitutions and modifications can be made according to common technical knowledge and customary means in the art, and all should be included in the scope of protection of the present invention.

[0045] Example 1:

[0046] See also Figures 1 to 11 This embodiment provides a high-toughness integrated pipeline corridor in a strong earthquake zone, including an inner segmented prefabricated integrated pipeline corridor, an outer prefabricated assembled enclosure structure and a universal rotating hinge support 1.

[0047] The inner segmented prefabricated integrated pipeline corridor includes several pipeline corridor segments Ⅰ14 arranged closely together. The two ends of the pipeline corridor segment Ⅰ14 along the length direction are respectively recorded as the front end face and the rear end face. The front end face and the rear end face are constructed with corresponding stepped edges. The front end face is provided with a groove Ⅰ3 for accommodating the water stop 4. Each pipeline corridor segment Ⅰ14 is spliced together through the stepped edges, and is connected and compressed by the steel strands 6 to form a continuous pipeline corridor. A multi-directional multi-tuned mass damper is provided at the tail end of each section of the steel strand 6 to reduce the influence of the multi-directional vibration of the steel strand 6 and increase the seismic resistance of the pipeline corridor.

[0048] The outer prefabricated assembled enclosure structure includes several sections of pipeline corridor segments Ⅱ2 arranged closely together. The two ends of the pipeline corridor segment Ⅱ2 along the length direction are respectively recorded as the front end face and the rear end face. The rear end face is provided with a side panel rear end face groove 8, and the front end face is provided with a side panel front end face groove 9 corresponding to the side panel rear end face groove 8. Each pipeline corridor segment Ⅱ2 is spliced section by section and connected and compressed by steel strands 6 to form a continuous pipeline corridor. A universal joint hinge is provided between adjacent pipeline corridor segments Ⅱ2. The universal joint hinge includes a side panel front end universal joint fork 21, a cross shaft and a side panel rear end universal joint fork 23 connected in sequence.

[0049] The front end universal joint fork 21 of the side panel is embedded in the front end face slot 9 of the side panel. The rear end universal joint fork 23 of the side panel is embedded in the rear end face slot 8 of the side panel. Under the action of the universal joint hinge, adjacent corridor segments II2 can slide vertically, horizontally and torsionally within a limited range.

[0050] The inner segmented prefabricated integrated pipe corridor is nested in the outer prefabricated assembled enclosure structure. A gap is left between the inner segmented prefabricated integrated pipe corridor and the outer prefabricated assembled enclosure structure as a deformation adjustment space. A universal rotating hinge support 1 is provided in the gaps between the inner segmented prefabricated integrated pipe corridor and the outer prefabricated assembled enclosure structure at the top, bottom, left and right. One end of the universal rotating hinge support 1 is fixedly connected to the outer prefabricated assembled enclosure structure, and the other end is pressed against the inner segmented prefabricated integrated pipe corridor. Figure 8 , Figure 88a and 8b represent different views of the universal hinge support 1. The universal hinge support 1 includes a top seat plate 26, a buffer rubber core 27, a laminated rubber 28 and a base plate 29. The top seat plate 26 is connected to the inner segmented prefabricated integrated pipe corridor, and the base plate 29 is connected to the outer prefabricated assembled enclosure structure. The buffer rubber core 27 and the laminated rubber 28 are placed between the top seat plate 26 and the base plate 29. The laminated rubber 28 is connected to the base plate 29 and is spaced apart from the top seat plate 26. Two rigid arms extend from the laminated rubber 28 on the side facing the top seat plate 26. The buffer rubber core 27 is arranged between the two rigid arms. A connecting rod and two force transmission rods are provided on the buffer rubber core 27. One end of the connecting rod is rotatably connected to the top seat plate 26 through a universal joint. The two force transmission rods are rotatably connected to the two rigid arms respectively. When an earthquake or foundation deformation occurs, the universal hinge support 1 is adaptively adjusted according to the deformation of the outer retaining structure. When the outer pipe corridor sinks downward due to vibration, the height of the bottom universal hinge support increases and the height of the top universal hinge support decreases; when the outer pipe corridor shifts to the left due to vibration, the height of the right universal hinge support increases and the height of the left universal hinge support decreases, thereby ensuring that there is less misalignment between the pipe sections of the internal pipe corridor; when the outer pipe corridor twists due to vibration, the presence of the universal hinge support hinge 27 can make the angle of the outer pipe corridor and the inner pipe corridor change and adjust, thereby ensuring that there is no large misalignment, additional stress and deformation between the segments of the internal segmented prefabricated integrated pipe corridor, overcoming the horizontal and vertical twisting deformation of the fault, thereby reducing the impact of the earthquake on the inner segmented prefabricated integrated pipe corridor.

[0051] The vertical and lateral displacements and torsional sliding of the outer prefabricated assembled enclosure structure of this embodiment can adapt to the foundation settlement deformation and protect the inner layer of the pipeline corridor from being affected.

[0052] Example 2:

[0053] The main structure of this embodiment is the same as that of embodiment 1, wherein the base plate 29 has a height adjustment function. The base plate 29 uses a hydraulic height adjustment support, or a conventional height adjustment support in the form of a filler, a wedge, a support plate, a support block, etc. in the prior art. These height adjustment supports can achieve the expected effect in the pipe gallery scenario. For height adjustment supports in the form of wedges, support plates, support blocks, etc., a hydraulic jack module needs to be added to achieve mechanical control adjustment. As for the hydraulic height adjustment support form, since its own adjustment method meets the autonomous height adjustment requirements, it can be directly selected.

[0054] Example 3:

[0055] The main structure of this embodiment is the same as that of embodiment 1 or 2, wherein waterproof fillers 5 and wedge-shaped rubber rings 7 are provided between adjacent tunnel sections I14 and between adjacent tunnel sections II2 to prevent groundwater penetration.

[0056] Example 4:

[0057] The main structure of this embodiment is the same as any one of the embodiments 1, 2 or 3, wherein it further includes side plate buttresses 13. The side plate buttresses 13 are arranged outside the outer prefabricated assembled enclosure structure.

[0058] Example 5:

[0059] The main structure of this embodiment is the same as any one of Embodiments 1, 2, 3, or 4, wherein the waterstop 4 is a water-swelling waterstop. The waterstop 4 is a water-swelling waterstop with high elasticity and compression deformation. When adjacent pipe gallery segments are connected by extrusion between the front and rear faces, the waterstop 4 is compressed and expands 2 to 3 times upon contact with water, filling all irregular surfaces, cavities, and gaps in the joints while generating enormous contact pressure to completely prevent leakage. When the joints or construction joints shift, causing the gaps to exceed the elastic range of the material, the waterstop 4 also stops the water by absorbing water and expanding, making the waterproofing effect more reliable. The pipe gallery segments I14 and II2 are cast using ECC concrete. Because the segmented integrated pipe gallery transverse panels are subject to high stress, they are prone to deformation and damage. Therefore, the outer protective layer and the inner segmented prefabricated integrated pipe gallery transverse panels are made of ECC high-ductility concrete, which has high strength, high toughness, high crack resistance, and high damage resistance.

[0060] Example 6:

[0061] The main structure of this embodiment is the same as that of Embodiment 1, 2, 3, 4 or 5, wherein the pipe gallery segment Ⅰ14 includes two horizontally arranged transverse plates Ⅰ and two vertically arranged side plates Ⅰ. The two side plates Ⅰ are connected between the two transverse plates Ⅰ and are arranged opposite to each other. The two transverse plates Ⅰ and the two side plates Ⅰ enclose the pipe gallery segment Ⅰ14. Both ends of the transverse plates Ⅰ and the side plates Ⅰ are provided with stepped edges. The transverse plates Ⅰ and the side plates Ⅰ are connected by a socket-type connection. The surface of the transverse plates Ⅰ is provided with a socket groove Ⅰ12 for the side plates Ⅰ to be inserted. The socket groove Ⅰ12 is provided with a waterstop 4 and a waterproof filler 5.

[0062] Example 7:

[0063] The main structure of this embodiment is the same as that of embodiment 1, wherein the pipe gallery segment Ⅱ2 includes two horizontally arranged transverse plates Ⅱ and two vertically arranged side plates Ⅱ. The two side plates Ⅱ are connected between the two transverse plates Ⅱ and are arranged opposite to each other. The two transverse plates Ⅱ and the two side plates Ⅱ enclose the pipe gallery segment Ⅱ2. Stepped edges are provided at both ends of the transverse plates Ⅱ. The front end surface of the transverse plate Ⅱ is provided with a groove Ⅱ15 for accommodating the waterstop 4. The transverse plate Ⅱ and the side plates Ⅱ are connected in a socket-type manner. The surface of the transverse plate Ⅱ is provided with a socket groove Ⅱ16 for the side plates Ⅱ to be inserted. The waterstop 4 and the waterproof filler 5 are provided in the socket groove Ⅱ16.

[0064] Example 8:

[0065] The main structure of this embodiment is the same as that of embodiment 1, wherein the gap between the inner segmental prefabricated integrated pipe corridor and the outer prefabricated assembled enclosure structure is filled with energy-absorbing flexible material 17. In this embodiment, polyurethane damping pads are selected.

[0066] Example 9:

[0067] The main structure of this embodiment is the same as that of embodiment 1, wherein the length of each section of the pipe gallery segment I 14 is a, and the length of each section of the pipe gallery segment II 2 is b, wherein a>b.

[0068] Example 10:

[0069] The main structure of this embodiment is the same as that of embodiment 1, wherein a supporting steel plate is placed on the upper surface of the universal hinge support 1. Anchor steel bars are welded to the upper surface of the supporting steel plate. The anchor steel bars are connected to the bottom plate of the inner segmental prefabricated integrated pipe corridor.

[0070] Example 11:

[0071] This embodiment provides a high-toughness integrated pipe corridor in a strong earthquake zone, wherein the internal integrated pipe corridor and the outer assembled enclosure structure are arranged in accordance with Figure 3 , Figure 4 , Figure 5 and Figure 6 The shape is prefabricated, with each section of the integrated pipe corridor being 1m and each section of the outer retaining structure being 0.8m. After being transported to the construction site, it is installed and spliced in sections of 8m. Before the pipe segments are in place, two stabilizing piers should be set in advance. After the first piece of the retaining structure is parked and stabilized at the designated position, the side panels should be firmly connected to the stabilizing piers. First, the bottom plate and side panels of the outer assembled retaining structure are spliced together, and 10 sections are installed. The tensioned steel strands compress the waterstop between the two end faces of adjacent pipe segments to exert the water-stopping and waterproofing functions, and the energy-consuming flexible materials are set up. Assemble the 8 sections of the internal segmental prefabricated integrated pipe corridor pipe segments. After the pipe corridor is spliced, the tensioned steel strands compress the waterstop between the two end faces of adjacent pipe corridor segments to exert the water-stopping and waterproofing functions. Then install the support and place a supporting steel plate slightly larger than the support plane on the support. The support and the integrated pipeline corridor are connected to the internal segmented prefabricated integrated pipeline corridor bottom plate by welding anchor steel bars on the steel plate. Finally, the top plate of the outer enclosure structure is installed to form an adaptively deformable integrated pipeline corridor that can be put into use.
