Description

Technical Field

[0001] This utility model relates to the field of utility tunnel technology, specifically a prefabricated integrated utility tunnel structure. Background Technology

[0002] With the acceleration of urbanization and the continuous expansion of urban scale, the number of various municipal pipelines, such as electricity, communications, water supply, drainage, and gas, is increasing daily. Traditional direct-buried pipeline laying methods have exposed numerous problems, such as repeated road excavation disrupting traffic, inconvenient pipeline maintenance, short service life, and low space utilization, seriously affecting the normal operation and sustainable development of cities. Integrated utility tunnels, as facilities that centrally lay multiple municipal pipelines in the same underground space, can effectively solve the above problems, achieve intensive use of urban underground space, improve the reliability and stability of urban infrastructure, and have become an inevitable choice for modern urban construction.

[0003] According to patent number CN220414317U, a prefabricated pipe gallery structure is disclosed, including a main body one and a main body two. The frame assembly includes an upper frame and a lower frame. A nut is rotatably connected to the upper frame, and a stud is fixedly connected to the lower frame. The nut and the stud are threaded together.

[0004] The above-mentioned solution allows for easy disassembly of the utility tunnel structure during implementation. However, it is inconvenient to waterproof the joints, and groundwater can easily seep into the utility tunnel through the gaps at the joints, thus affecting the service life of the internal pipelines. Therefore, we provide a prefabricated integrated utility tunnel structure to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a prefabricated integrated utility tunnel structure to solve the problems raised in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a prefabricated integrated utility tunnel structure, comprising prefabricated modules, wherein a set of barrier plates are fixedly connected inside the prefabricated modules, and assembly plates are fixedly connected to both ends of the prefabricated modules; two sets of sealing frames and sealing strips are provided on the outside of the prefabricated modules; two sets of connecting structures are provided on the outside of the sealing frames; the connecting structures include slots formed on the surface of the sealing frames; snap-fit ​​blocks are fixedly connected inside the slots; a rotating shaft is rotatably connected to the end of the snap-fit ​​blocks; and a snap-fit ​​buckle frame is fixedly connected to the outer surface of the rotating shaft; the snap-fit ​​buckle frame is adapted to the snap-fit ​​blocks.

[0007] Preferably, each of the sealing frames and sealing strips is slidably connected to the prefabricated module, and each of the sealing frames and sealing strips is adapted to the assembly plate, with the sealing frames and sealing strips serving to fix the two assembly plates.

[0008] Preferably, both the sealing frame and the sealing strip have a set of threaded holes inside, and each threaded hole is threaded with a fastening bolt. The sealing frame and the sealing strip can prevent groundwater from seeping into the prefabricated module through the gaps.

[0009] Preferably, a limiting rotating rod is provided inside the sealing frame. The limiting rotating rod passes through the sealing frame and is rotatably connected to the sealing frame. The limiting rotating rod is fixedly connected to the rotating shaft, and the limiting rotating rod has the effect of fixing the rotating shaft.

[0010] Preferably, a limiting bolt is slidably connected to the outer surface of the limiting rotating rod, and the limiting bolt is threadedly connected to the sealing frame, so that the limiting bolt can be fixed by the thread.

[0011] Preferably, a fixing strip is fixedly connected inside the sealing frame. The fixing strip is adapted to the limiting bolt and serves to fix the limiting rotating rod.

[0012] Preferably, the internal space of the prefabricated module is divided into a natural gas compartment, a pipeline compartment, and a power line compartment by a partition plate, which serves to separate the spaces.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This application, through the setting of structures such as sealing frames, sealing strips and connecting structures, can shield and protect the connection points of prefabricated pipe corridors, prevent groundwater from seeping into the prefabricated modules and causing damage to the internal pipelines, extend the service life of the internal pipelines of the pipe corridor, and improve the connection stability of the pipe corridor through fastening bolts and connecting structures, improve the construction efficiency of the pipe corridor, and facilitate subsequent expansion or renovation of the pipe corridor.

[0015] 2. This application uses a snap-fit ​​frame, a rotating shaft, a limiting bolt, and a fixing strip.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] This utility model provides a technical solution for a prefabricated integrated utility tunnel structure.

[0028] like Figure 1 - Figure 5As shown, the prefabricated module 1 and the barrier panel 2 are manufactured entirely in the factory and then transported to the installation site for direct installation. This significantly shortens the construction cycle, quickly meets the needs of urban construction for underground integrated utility tunnels, reduces the impact on urban traffic and residents' lives, and ensures the stability of the factory production environment. The use of advanced production equipment and a strict quality control system effectively guarantees the consistency and stability of product quality. The strength, dimensional accuracy, and waterproof performance of the prefabricated modules are superior to those of on-site cast-in-place construction, reducing potential quality risks and extending the service life of the utility tunnel. Furthermore, the modular design makes it easier to expand or renovate the utility tunnel later. Only the corresponding modules need to be added or replaced as needed, without the need for large-scale demolition and reconstruction of the entire utility tunnel, thus improving the scalability of the system.

[0029] A set of partition plates 2 are fixedly connected inside the prefabricated module 1. The internal space of the prefabricated module 1 is divided into a natural gas compartment 21, a pipeline compartment 22, and a power line compartment 23 by the partition plates 2. The partition plates 2 can be used to divide the internal space. The size and number of the specific compartments can be designed and manufactured according to the actual installation environment requirements. In this application, the internal space of the partition plates 2 is divided into three areas: natural gas compartment 21, pipeline compartment 22, and power line compartment 23, according to common practice. This facilitates the classification and installation of related supporting facilities by staff and facilitates the subsequent maintenance and replacement of pipelines inside the integrated utility tunnel.

[0030] Both ends of the prefabricated module 1 are fixedly connected to assembly plates 3. Each sealing frame 4 and sealing strip 5 is adapted to the assembly plate 3. The assembly plate 3 has a certain degree of groove inside, which facilitates the sealing frame 4 and sealing strip 5 to fix the two assembly plates 3 together through the groove, thereby completing the modular assembly of the prefabricated module 1. This greatly reduces the construction time of traditional cast-in-place integrated pipe gallery. Traditional cast-in-place integrated pipe gallery requires a series of procedures on site, such as rebar binding, formwork erection, concrete pouring and curing. Each procedure takes a lot of time and is greatly affected by external factors such as weather, resulting in a long overall construction cycle. For example, in the rainy season or in low-temperature winter conditions, the time for concrete pouring and curing will be significantly extended, and the project progress will be forced to slow down. However, this application can quickly fix the assembly plate 3 through the sealing frame 4 and sealing strip 5, thereby achieving the purpose of rapid installation of pipe gallery and improving construction efficiency.

[0031] The prefabricated module 1 is externally equipped with two sets of sealing frames 4 and sealing strips 5. Each sealing frame 4 and sealing strip 5 is slidably connected to the prefabricated module 1. Each sealing frame 4 and sealing strip 5 has a set of threaded holes inside, and each threaded hole is threaded with a fastening bolt 6. The sealing frames 4 and sealing strips 5 are divided into upper and lower sets. The main purpose is to facilitate the insertion of the sealing frames 4 and sealing strips 5 into the grooves of the assembly plate 3. After the sealing frames 4 and sealing strips 5 are moved into place, the workers fix the sealing frames 4 and sealing strips 5 together through the fastening bolts 6 and threaded holes, thereby realizing the fixing operation of the two connected assembly plates 3, and thus completing the assembly installation of the prefabricated module 1. Through the setting of the sealing frames 4 and sealing strips 5, there is a good sealing effect between the sealing frames 4 and sealing strips 5, and the sealing frames 4 can block the connection between the two prefabricated modules 1, thereby preventing groundwater from seeping into the prefabricated module 1 and damaging the internal pipelines.

[0032] The sealing frame 4 is provided with two sets of connecting structures 7 on its exterior. The connecting structure 7 includes a slot opened on the surface of the sealing frame 4. A snap-fit ​​block 701 is fixedly connected inside the slot. The connecting structure 7 mainly serves to connect and fix the two sealing frames 4. The two sets of connecting structures 7 are respectively set at both ends of the sealing frame 4, which can fix the ends of the upper and lower sets of sealing frames 4 together, further improving the connection stability of the sealing frame 4 and sealing strip 5 to the prefabricated module 1, and preventing groundwater from entering the prefabricated module 1 through the gap between the two sealing frames 4.

[0033] The end of the snap-fit ​​block 701 is rotatably connected to a rotating shaft 702. A snap-fit ​​buckle frame 703 is fixedly connected to the outer surface of the rotating shaft 702. The snap-fit ​​buckle frame 703 is adapted to the snap-fit ​​block 701. When the positions of the two sealing frames 4 are determined, the operator can move the snap-fit ​​buckle frame 703 to snap it onto the snap-fit ​​block 701, thereby completing the fixation between the two sealing frames 4 and further improving the connection stability of the sealing frames 4. The slide groove and the snap-fit ​​block 701 can limit and clamp the snap-fit ​​buckle frame 703, so that the snap-fit ​​buckle frame 703 remains stably snapped.

[0034] The sealing frame 4 is provided with a limiting rod 704 inside. The limiting rod 704 passes through the sealing frame 4 and is rotatably connected to the sealing frame 4. The limiting rod 704 is fixedly connected to the rotating shaft 702. The limiting rod 704 is used to limit the rotation of the rotating shaft 702 so as to achieve a stable engagement between the snap-fit ​​frame 703 and the snap-fit ​​block 701 and prevent the snap-fit ​​frame 703 from falling off the snap-fit ​​block 701 due to external vibration or collision. The surface of the limiting rod 704 is provided with a high-friction limiting ring to facilitate the fixing strip 706 to limit and fix the limiting rod 704.

[0035] A limiting bolt 705 is slidably connected to the outer surface of the limiting rod 704. The limiting bolt 705 is threadedly connected to the sealing frame 4. A fixing strip 706 is fixedly connected inside the sealing frame 4. The fixing strip 706 is adapted to the limiting bolt 705. The ends of the limiting bolt 705 and the fixing strip 706 have the same inclined arc. One end of the fixing strip 706 has teeth with high friction. When the operator rotates the snap-fit ​​frame 703 to a suitable position, the snap-fit ​​frame 703 is fixed by rotating the limiting bolt 705. When the limiting bolt 705 is screwed into the sealing frame 4, the end of the limiting bolt 705 will gradually squeeze the end of the fixing strip 706, so that the teeth at the end of the fixing strip 706 can squeeze the limiting ring on the limiting rod 704, thereby fixing the limiting rod 704 and thus fixing the snap-fit ​​frame 703.

[0036] Working principle: When the staff assembles and installs this pipe gallery structure, first place the two prefabricated modules 1 in suitable fixed positions, then slide the two sets of sealing frames 4 and sealing strips 5 on the two prefabricated modules 1 respectively. After the sealing frames 4 and sealing strips 5 are tightly abutted against the assembly plate 3, the staff screws the fastening bolts 6 into the threaded holes, then fastens the snap-fit ​​frame 703 onto the snap-fit ​​block 701, and then rotates the limiting bolt 705. The rotation of the limiting bolt 705 can fix the limiting rotating rod 704 by squeezing the end of the fixing strip 706, thereby fixing the snap-fit ​​frame 703. Then, the next prefabricated module 1 can be installed according to the above steps.

[0037] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
