Description

Technical Field

[0001] This utility model relates to the field of pipe gallery technology, and in particular to an integrated prefabricated pipe gallery. Background Technology

[0002] Precast concrete utility tunnels are a type of urban underground utility tunnel where pipe sections are prefabricated in a factory and assembled on-site. Their technological development stems from innovations aimed at addressing the problems of long construction cycles, significant environmental impact, and poor quality control inherent in traditional cast-in-place utility tunnels. Through standardized design and industrialized production, precise control of component quality and a significant improvement in construction efficiency have been achieved. The core of this technology lies in the manufacturing of high-precision precast components and their rapid on-site assembly. Key technologies include joint connections, waterproofing and sealing, and precision control, making it an important technological path for promoting the intensive and standardized construction of urban underground spaces.

[0003] However, existing integrated prefabricated pipe racks have the following drawbacks: First, the waterproofing performance of the joints between adjacent pipe racks is weak. The joints between pipe sections (mainly using socket joints, bolt connections, etc.) are the weakest link in waterproofing, and the sealing rings are prone to failure under long-term uneven settlement or construction deviations, leading to leakage. Second, prefabricated pipe racks are rigid structures and are very sensitive to uneven settlement of the foundation. If the foundation is not properly treated, stress concentration can easily occur at the joints or in the components themselves, leading to cracking. Third, adjacent pipe racks are connected by long bolts passing through the four corner slots. Even a slight deviation in the pipe rack connection can prevent the long bolts from passing through the slots, making installation difficult. Therefore, further improvements are needed. To this end, we propose an integrated prefabricated pipe rack. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an integrated prefabricated pipe gallery.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an integrated prefabricated pipe gallery, comprising a pipe gallery body, the pipe gallery body being U-shaped, and an annular insertion part fixed at one end of the pipe gallery body, and an insertion groove for engaging the insertion part at the other end of the pipe gallery body, a second annular groove being formed on the outer surface of the insertion part, a casting port being formed at the top of the insertion groove, connecting blocks being fixed on the bottom wall and top surface of the inner wall of the pipe gallery body, and multiple side holes being formed on both sides of the pipe gallery body, with a reinforcing pipe passing through the interior of each side hole.

[0006] Furthermore, the main end face of the pipe gallery is provided with a first annular groove on both the inner and outer sides of the insertion groove, and a waterproof adhesive strip is snapped into the inside of the first annular groove.

[0007] Furthermore, the connecting blocks of two adjacent pipe gallery bodies fit together, and a connecting hole is provided in the middle of the connecting block, through which a bolt passes.

[0008] Furthermore, two adjacent pipe gallery bodies are spliced ​​together by a plug-in part and a plug-in groove, and the pouring port is connected to the second annular groove.

[0009] Furthermore, the side holes and reinforcing tubes are designed to slope downwards, and the sidewalls of the reinforcing tubes have multiple slots.

[0010] Furthermore, multiple lifting rings are fixed on the upper surface of the main body of the pipe gallery.

[0011] Furthermore, through slots are provided at the two top corners of the main body of the utility tunnel, and steel bars are inserted into the through slots of two adjacent main bodies of the utility tunnel.

[0012] The beneficial effects of this utility model are: In use, this utility model comprises a pipe gallery main body, a plug-in part, a plug-in groove, a first annular groove, a waterproof strip, a second annular groove, a pouring port, and a connecting block. The pipe gallery main body is first precisely connected through the plug-in part and the plug-in groove, at which point the waterproof strip provides the first layer of waterproofing. Then, by pouring concrete into the second annular groove, the waterproofing effect at the connection point of the two pipe gallery main bodies is further improved. Secondly, the connecting block replaces the original long screw connection method, making the connection of the two pipe gallery main bodies simpler and faster, and reducing the assembly difficulty.

[0013] 2. When using this utility model, a pipe gallery main body, side holes and reinforcing pipes are set. After the pipe gallery main body is installed, the reinforcing pipes are inserted into the soil layer on the side through the side holes. The reinforcing pipes are used to increase the stability of the pipe gallery main body and prevent the pipe gallery main body from settling. Attached Figure Description

[0017] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0018] like Figures 1-5 As shown, an integrated prefabricated pipe gallery is disclosed, comprising a pipe gallery body 1, which is U-shaped, with an annular insertion part 2 fixed at one end of the pipe gallery body 1 and an insertion groove 3 for inserting into the insertion part 2 at the other end of the pipe gallery body 1. A second annular groove 6 is provided on the outer surface of the insertion part 2, and a pouring port 7 is provided at the top of the insertion groove 3. Connecting blocks 8 are fixed on the bottom wall and the top surface of the pipe gallery body 1. Multiple side holes 9 are provided on both sides of the pipe gallery body 1, and a reinforcing pipe 10 is inserted inside each side hole 9.

[0019] In this embodiment, a first annular groove 4 is provided on the end face of the main body 1 of the pipe gallery, both inside and outside the insertion groove 3, and a waterproof strip 5 is snapped into the inside of the first annular groove 4.

[0020] Among them, the waterproof strip 5 is a water-swellable strip, and the waterproof strip 5 plays a preliminary waterproofing role at the joint of the two pipe gallery main bodies 1, the insertion part 2 and the insertion groove 3.

[0021] The connecting blocks 8 of two adjacent pipe gallery main bodies 1 fit together, and a connecting hole is opened in the middle of the connecting block 8, and a bolt is inserted inside the connecting hole.

[0022] In this embodiment, multiple sets of connecting blocks 8 are provided. When two pipe rack bodies 1 are spliced ​​together through the insertion part 2 and the insertion slot 3, the connecting blocks 8 at the same position on the two adjacent pipe rack bodies 1 will move closer to each other. At this time, bolts are inserted into the connecting holes and nuts are tightened to achieve a fixed connection between the two connecting blocks 8, thus realizing the assembly between the two adjacent pipe rack bodies 1. This method is simpler and more convenient than the current method of first connecting all the pipe rack bodies 1 and then inserting long bolts into the four corner slots. Workers can connect the connecting blocks 8 by standing inside the pipe rack body 1 or on top of the pipe rack body 1. Here, the bolts serve to connect the two pipe rack bodies 1, and the insertion part 2 and the insertion slot 3 serve as the main support between the two pipe rack bodies 1.

[0023] Two adjacent pipe rack bodies 1 are joined together by a splice 2 and a splice groove 3. After the two pipe rack bodies 1 are joined together by the splice 2 and the splice groove 3, the pouring port 7 is connected to the second annular groove 6. At this time, cement grout can be poured into the second annular groove 6 through the pouring port 7 to completely fill the second annular groove 6, further increasing the sealing of the connection between the two adjacent pipe rack bodies 1 and achieving further waterproofing.

[0024] The side hole 9 and the reinforcing tube 10 are designed to be inclined downwards. The reinforcing tube 10 is made of metal and has multiple slots on its side wall.

[0025] After all the main bodies 1 of the utility tunnel are assembled, the reinforcing pipe 10 is driven through the side hole 9 and into the soil layer on the side using a hammering device. Then, concrete is poured into the inside of the reinforcing pipe 10. The concrete can flow out from the strip-shaped opening on the side of the reinforcing pipe 10, increasing the connection strength between the reinforcing pipe 10 and the soil layer. The reinforcing pipe 10 also provides further support for the main body 1 of the utility tunnel, preventing the main body 1 of the utility tunnel from settling. This also prevents the connection between the two main bodies 1 of the utility tunnel from breaking and the waterproofing effect from deteriorating due to settlement.

[0026] Multiple lifting rings 12 are fixed to the upper surface of the main body 1 of the utility tunnel. It is a prefabricated structure, and the main body 1 of the utility tunnel can be lifted by connecting it to the lifting rings 12 with lifting equipment.

[0027] Each of the two top corners of the main pipe gallery 1 has a through groove 11, and steel bars are threaded through the through groove 11 of two adjacent main pipe gallery 1s. The length of the steel bars does not have to completely penetrate the through groove 11. Compared with the existing bolts that completely penetrate the through groove 11, the installation of steel bars is more convenient. The steel bars here serve as supports between two adjacent main pipe gallery 1s.

[0028] Working principle: When assembling the two main pipe racks 1, first insert a steel bar into the through groove 11 of one main pipe rack 1, then insert the plug part 2 of one main pipe rack 1 into the plug groove 3 of the other main pipe rack 1, at which time the steel bar is also inserted into the through groove 11 of the other main pipe rack 1; after the above docking operation is completed, use bolts to connect the connecting blocks 8 of the inner bottom wall and the upper surface of the two main pipe rack 1; after assembling all the main pipe racks 1 in this way, pour concrete into the pouring port 7 at the top of each main pipe rack 1, so that the concrete fills the second annular groove 6; finally, insert a reinforcing pipe 10 into the side hole 9 of each main pipe rack 1, and drive the reinforcing pipe 10 through the side hole 9 and into the soil layer on the side by a hammering device, then pour concrete into the reinforcing pipe 10, and the concrete can flow out from the strip-shaped opening on the side of the reinforcing pipe 10, increasing the connection strength between the reinforcing pipe 10 and the soil layer, while the reinforcing pipe 10 also plays a further supporting role for the main pipe rack 1, preventing the main pipe rack 1 from settling.
