Abstract
Description
Technical Field
[0001] This application relates to the field of utility tunnel equipment, and more particularly to a collection tray structure for utility tunnels. Background Technology
[0002] Utility tunnels are an important component of modern urban infrastructure, widely used in municipal engineering, industrial production, and residential life. Because utility tunnels house a dense concentration of pipes, when sewage leaks from one pipe, it drips onto the pipes below and splashes in all directions. The side panels of the utility tunnel act as a barrier, preventing sewage from splashing into the external environment and ensuring public safety and environmental hygiene. The tray of the utility tunnel structure is located at its bottom and is horizontal. Sewage flows along the side panels to the tray, forming a pool. A drainage trough is connected to the bottom of the tray to drain the water above it.
[0003] To address this challenge, horizontal pipe gallery structures are typically unable to quickly and effectively drain accumulated water, especially after prolonged accumulation, which can easily lead to poor water flow or even blockages. Therefore, there is still room for improvement. Summary of the Invention
[0004] To facilitate the drainage of accumulated water, this application provides a collection tray structure for pipe racks.
[0005] The technical solution for a collection tray structure for pipe racks provided in this application is as follows:
[0006] A collection pallet structure for a pipe gallery includes a pallet body and a base frame for supporting the pallet body. The pallet body is recessed and has a sunken section. The two side walls of the sunken section are inclined towards the bottom wall of the sunken section. The bottom wall of the sunken section is connected to a drainage channel for draining water accumulated on the pallet body.
[0007] By adopting the above technical solution, the sunken design of the pallet body can effectively collect accumulated water and accelerate the flow of water to the drainage channel using the inclined sidewalls, thereby improving drainage efficiency and reducing the possibility of water accumulation. At the same time, this structure helps to reduce the retention of dirt on the pallet surface, reducing the workload of cleaning and maintenance.
[0008] Preferably, the bottom wall of the sunken position is inclined along the extension direction of the sunken position.
[0009] By adopting the above technical solution, the bottom wall of the recessed area is inclined along the extension direction of the recess, which can effectively guide the accumulated water to flow quickly to the drainage channel, avoid water accumulation on the pallet body, and improve drainage efficiency. This helps to reduce environmental pollution and safety hazards caused by sewage leakage, while extending the service life of the pallet structure.
[0010] Preferably, both sides of the sunken position are provided with a number of protrusions that are spaced apart along the extension direction of the sunken position, and the number of protrusions extends along the inclined direction of the side wall of the sunken position.
[0011] By adopting the above technical solution, leaked sewage can be effectively guided to flow quickly into the drainage ditch along the side wall of the submerged area, reducing the residence time of sewage on the tray and lowering the risk of secondary pollution caused by sewage evaporation. At the same time, the raised design can also enhance the guidance of water flow, ensuring that sewage flows smoothly into the drainage ditch, further improving the safety and environmental performance of the pipe gallery structure.
[0012] Preferably, the inner bottom wall of the drainage trough is inclined.
[0013] By adopting the above technical solution, the inclined design of the inner bottom wall of the drainage ditch can effectively promote the rapid discharge of accumulated water along the inclined surface, preventing water from accumulating in the drainage ditch and improving drainage efficiency. At the same time, the inclined design also reduces the possibility of water residue and lowers the risk of secondary pollution.
[0014] Preferably, the drainage trough is provided with several partitions, which are distributed at intervals along the inclined direction of the bottom wall of the drainage trough. The distance from the bottom of the partitions to the bottom wall of the drainage trough is equal. The side of the partitions facing the upper end of the inclined bottom wall of the drainage trough is the water-facing side. A water level sensor is provided on the water-facing side of each partition. When the water level sensors of the partitions distributed along the inclined direction of the drainage trough detect water accumulation in sequence, it is determined that there is a sewage leak in the pipes inside the pipe gallery.
[0015] By adopting the above technical solution, each partition maintains a certain distance from the bottom wall of the drainage ditch, and a water level sensor is installed on the water-facing side of each partition. When water in the drainage ditch flows along the inclined direction and sequentially triggers the water level sensors on each partition, it can be accurately determined that a sewage leak has occurred in the pipe gallery. If all water level sensors are activated simultaneously or only some sensors are detected individually, it may be a false alarm caused by rainfall or the passage of a water truck, thus improving the accuracy of leak detection.
[0016] Preferably, there are at least two sunken positions at the tray, and several sunken positions are distributed in the width direction of the pipe gallery structure and extend along the length direction of the pipe gallery structure. When several water level sensors in the drainage trough of one of the sunken positions detect water accumulation in sequence, it is preliminarily judged that there is a sewage leak in the pipe directly above this sunken position.
[0017] By adopting the above technical solutions, the pipe gallery structure can effectively address the problem of pipe leakage. Specifically, by setting multiple submerged locations distributed along the width and extending along the length of the pipe gallery, it can be ensured that sewage from different areas can be collected and diverted to the drainage ditch in a timely manner, preventing sewage accumulation and secondary pollution. Several water level sensors are installed in the drainage ditch corresponding to each submerged location. This allows the system to quickly determine if a leak is possible in the pipe above a certain area when continuous water accumulation occurs, thus rapidly locating the fault point. This facilitates timely handling by maintenance personnel and piston repair robots, reducing the negative impact on the entire system. The design of multiple submerged locations not only improves the efficiency of sewage collection but also enhances the reliability and safety of the system, helping to ensure the cleanliness of the surrounding environment and the safety of residents.
[0018] Preferably, the pallet body comprises several pallet units, which are sequentially spliced together along the length of the pipe gallery.
[0019] By adopting the above technical solution, the pallet body is composed of several pallet units spliced sequentially along the length of the pipe rack, which effectively improves the overall stability and ease of installation of the pallet. This modular design allows each pallet unit to be prefabricated in the factory, ensuring quality while reducing on-site construction time and costs. In addition, when a pallet in a certain area needs repair or replacement, only the corresponding pallet unit needs to be replaced, without having to dismantle the entire pallet structure, thus improving maintenance efficiency.
[0020] Preferably, a waterproof structure is provided at the connection between adjacent tray units.
[0021] By adopting the above technical solution, a waterproof sealing structure is set at the connection between adjacent pallet units, which effectively prevents water from seeping out from the connection gap and improves the waterproof performance and reliability of the entire collection pallet structure.
[0022] Preferably, the pallet body is provided with expansion joints at intervals along the length of the pipe gallery.
[0023] By adopting the above technical solution, expansion joints are provided at intervals along the length of the pipe gallery, which can effectively adapt to the deformation of the pipe gallery caused by thermal expansion and contraction under different ambient temperatures, avoid cracking or damage of the pallet due to temperature changes, and improve the overall stability and service life of the pallet structure.
[0024] Preferably, the tray unit is a one-piece molded stainless steel plate.
[0025] By adopting the above technical solution, the pallet unit uses a one-piece molded stainless steel plate, which has good corrosion resistance and mechanical strength, effectively resisting the erosion of various chemical substances inside the pipe rack and extending its service life. At the same time, the one-piece molding design reduces welding points and connection gaps, improving the overall stability and sealing of the structure, avoiding problems caused by water leakage at welds or joints, and ensuring the effective collection and drainage of accumulated water.
[0026] In summary, this application includes at least one of the following beneficial technical effects:
[0027] 1. Both side walls of the sunken area are inclined towards the bottom wall of the sunken area, so that water can be collected at the bottom more quickly and effectively discharged through the drainage channel, avoiding the problems of poor water flow or blockage caused by traditional horizontal trays.
[0028] 2. Several baffles are installed in the drainage trough. The baffles are distributed at intervals along the inclined direction of the bottom wall of the drainage trough. The distance from the bottom of the baffle to the bottom wall of the drainage trough is equal. A water level sensor is installed on the water-facing side of the baffle. When the water level sensors of multiple baffles detect water accumulation in sequence, it can be determined that there is a sewage leak in the pipes inside the pipe gallery, so that timely warnings can be issued and measures can be taken.
[0029] 3. The pallet body is composed of several pallet units, which are spliced together sequentially along the length of the pipe rack, facilitating installation and maintenance, while enhancing the stability and flexibility of the overall structure. Attached Figure Description

[0033] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.
[0034] This application discloses a collection tray structure for pipe racks, referring to... Figure 1 and Figure 2The system includes a pallet body 2 and a base frame 1 for supporting the pallet body 2. The pallet body 2 has a recessed section 22, and both side walls of the recessed section 22 are inclined towards the bottom wall of the recessed section 22. The bottom wall of the recessed section 22 is connected to a drainage channel 3 for draining water accumulated on the pallet body 2. This design can effectively improve the problem of poor drainage in traditional horizontal pallets, improve drainage efficiency, and avoid safety hazards and environmental pollution caused by prolonged water retention.
[0035] In this embodiment, the pallet body 2 includes several pallet units 21, which are sequentially spliced along the length of the pipe rack for easy transportation and installation. Adjacent pallet units 21 are connected by rivets, and the joints between adjacent pallet units 21 are equipped with a waterproof sealing structure, such as neutral structural adhesive, to ensure the sealing performance of the joints and prevent moisture leakage. In addition, expansion joints are provided every 50m along the length of the pipe rack in the pallet body 2. These expansion joints are made of soft rubber and fixed with rivet plates on both sides to accommodate thermal expansion and contraction caused by temperature changes, maintaining the long-term stability of the pallet structure.
[0036] The pallet unit 21 is integrally formed from a single 0.3mm thick stainless steel plate through stamping, bending, and reinforcement, exhibiting excellent corrosion resistance and pressure resistance. The base frame 1 is assembled from multiple sections of irregularly shaped structural members, which are bolted to the bottom of the pipe rack, ensuring the stability of the entire pallet structure. These irregularly shaped structural members are non-standard parts, machined from cut plates, achieving both sufficient load-bearing capacity and cost-effectiveness. The recessed area 22 is designed to allow accumulated water to flow quickly to the drainage trough 3, reducing the time water remains on the pallet surface. The two side walls of the recessed area 22 are V-shaped and inclined at an angle of approximately 10º to 30º, ensuring sufficient drainage slope while minimizing space occupation under the pipes.
[0037] The bottom wall of the sunken section 22 is inclined along its extension direction, that is, slightly inclined along the length of the pipe gallery, so that accumulated water can flow more smoothly into the drainage trough 3. The inclination angle is about 5 degrees, which does not affect the overall flatness of the tray and can significantly improve the drainage speed. In addition, several protrusions 23 are provided on both sides of the sunken section 22, which are spaced apart along the extension direction of the sunken section 22. These protrusions 23 extend along the inclined direction of the side wall of the sunken section 22, which can effectively guide the leaked sewage to flow quickly into the drainage trough 3 along the side wall of the sunken section 22, reduce the residence time of sewage on the tray, and reduce the risk of secondary pollution caused by sewage evaporation. At the same time, the design of the protrusions 23 can also enhance the guidance of water flow, ensure that sewage flows smoothly into the drainage trough 3, and further improve the safety and environmental performance of the pipe gallery structure.
[0038] A drainage trough 3 is located within the recessed area 22 of the tray. The inner bottom wall of the drainage trough 3 is inclined at an angle of approximately 5°-10° to facilitate smooth water drainage. Multiple partitions 31 are installed within the drainage trough 3, spaced 50-100 cm apart along the inclined direction of the inner bottom wall to form multiple compartments. The compartment located at the lower end of the inclined bottom wall of the drainage trough 3 is connected to a drain pipe to drain accumulated water. The distance from the bottom of the partition 31 to the inner bottom wall of the drainage trough 3 is equidistant. Accumulated water can pass through the gap between the bottom wall of the drainage trough 3 and the bottom of the partition 31. When a sewage leak occurs, the volume of water is usually large, and the gap cannot accommodate the water flow. This causes the previous compartment to overflow, and then overflow from the top of the partition 31 to the next compartment.
[0039] In this embodiment, a water level sensor is installed on the water-facing side of the partition 31. When the water level sensors of several partitions 31 distributed along the inclined direction of the drainage channel 3 detect water accumulation in sequence, it is determined that there is a sewage leak in the pipes inside the pipe gallery structure. If all water level sensors are activated at the same time or only some sensors are sensed individually, it may be a false alarm caused by rainfall or the passage of a water truck, thereby improving the accuracy of leak detection.
[0040] In other embodiments, the tray is provided with multiple recessed positions 22, and each recessed position 22 is connected to at least two drainage channels 3. These drainage channels 3 are spaced apart along the extension direction of the recessed positions 22. When several water level sensors in one of the drainage channels 3 of one of the recessed positions 22 sequentially detect water accumulation, it can be preliminarily determined that a sewage leak has occurred in the pipes surrounding that drainage channel 3. That is, when continuous water accumulation occurs in a certain area, the system can quickly determine that a leak may have occurred in the pipes above that area, thereby quickly locating the fault point. This facilitates timely handling by maintenance personnel and piston repair robots, reducing the negative impact on the entire system. The design of multiple recessed positions 22 and multiple drainage channels 3 not only improves the efficiency of sewage collection but also enhances the reliability and safety of the system, helping to ensure the cleanliness of the surrounding environment and the safety of residents.
[0041] The implementation principle of this embodiment is as follows:
[0042] Through the above design, this invention proposes a highly efficient pipe gallery collection tray structure, which not only solves the problem of poor drainage in traditional horizontal trays but also has an automatic leakage detection function, improving the safety and environmental performance of the pipe gallery. In particular, the design of the recessed position 22 and the drainage channel 3 allows accumulated water to be discharged quickly, reducing the risks caused by water accumulation. At the same time, the modular tray unit 21 design and the application of a waterproof sealing structure make this tray structure more flexible and reliable, suitable for various complex environmental conditions.
[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
