Description

TECHNICAL FIELD

[0001] The present application relates to the field of urban infrastructure construction, and in particular to a pipe gallery structure. BACKGROUND

[0002] The pipe gallery structure is an important part of modern urban infrastructure and is widely used in municipal engineering, industrial production and residential life. The pipe gallery is closed at both ends, and some pipe galleries are as long as several kilometers. Since the pipe gallery internally contains relatively dense pipelines, when sewage in a pipeline leaks, it will drip onto the pipeline below and splash in all directions. Traditional pipe gallery designs usually adopt a fully closed structure to prevent the splashing of pollutants in the pipeline into the external environment, thereby ensuring public safety and environmental hygiene. However, since the pipe gallery is closed at both ends and the length of some pipe galleries reaches several kilometers, this long-distance closed pipe gallery structure also brings some new problems, particularly in terms of poor heat dissipation performance, which leads to high internal temperatures, affecting the normal operation and service life of equipment. Since heavy metal sewage in the pipelines inside the pipe gallery cannot leak into the external environment, there is an urgent need to improve the ventilation efficiency of the pipe gallery.

[0003] To solve the above problems, various methods have been adopted in the prior art to improve the ventilation and heat dissipation performance of the pipe gallery. For example, some designs adopt a natural ventilation method, with ventilation windows provided on the side of the pipe gallery to achieve heat dissipation while expelling hot air. Some designs also provide air exchange holes on the wall of the pipe gallery to increase the frequency of air exchange between the inside and outside to improve heat dissipation efficiency. These measures can alleviate the problem of high internal temperatures to some extent, but still have obvious shortcomings in practical application.

[0004] Specifically, existing ventilation design schemes often cannot take into account the need for leak prevention. When sewage leaks inside the pipe gallery, there is still a high probability that the splashing sewage will leak out of the pipe gallery through the ventilation windows or air exchange holes, causing the spread of pollutants to the external environment, which not only increases the risk of environmental pollution, but also can endanger the health of surrounding residents. Therefore, how to ensure good ventilation and heat dissipation performance while effectively preventing the leakage of internal pollutants has become a key technical problem to be solved. SUMMARY

[0005] To ensure good ventilation and heat dissipation performance while effectively preventing the leakage of internal pollutants, the present application provides a pipe gallery structure.

[0006] The pipe gallery structure provided by the present application adopts the following technical solution:

[0007] The utility model provides a pipe gallery structure, which comprises a framework, side plates arranged on both sides of the framework, a top plate arranged on the top of the framework, and a supporting plate arranged on the bottom of the framework, wherein a ventilation opening is formed through the top plate, a baffle is arranged at a top position in the framework to cover the lower part of the ventilation opening, the baffle has a ventilation gap with the ventilation opening, and a drainage groove is arranged on the supporting plate to drain the accumulated water on the supporting plate.

[0008] By adopting the above technical scheme, the pipe gallery structure can effectively balance the needs of ventilation and heat dissipation and leakage prevention. First, the ventilation opening on the top plate cooperates with the design of the baffle to ensure the internal air circulation while effectively preventing the possibility of sewage splashing into the external environment. Second, the drainage groove design on the supporting plate can timely drain the accumulated water, reducing the safety hazards caused by sewage accumulation. In summary, the scheme not only improves the ventilation and heat dissipation performance of the pipe gallery, but also significantly enhances the leakage prevention capability, ensuring public safety and environmental hygiene.

[0009] Preferably, a sealing strip is arranged at the gap between the side of the side plate and the framework.

[0010] By adopting the above technical scheme, the sealing strip reduces the penetration of sewage through the gap between the side plate and the framework when leaking, thereby better protecting the external environment from pollution.

[0011] Preferably, the side plate is arranged in a vertically extending wave shape.

[0012] By adopting the above technical scheme, the vertically extending wave-shaped side plate can enhance the overall rigidity and stability of the pipe gallery structure, improve the compression resistance, and reduce the risk of deformation. When the wave-shaped side plate is impacted, the wave lines on its surface can more effectively disperse the impact force. This dispersion can reduce the situation of excessive local stress, thereby reducing the risk of structural damage. The wave-shaped design increases the surface area of the side plate, which to some extent enhances its structural strength. The larger surface area means that more material is involved in the stress, thereby improving the overall load-bearing capacity. In addition, the wave-shaped structure can also resist external pressure through its unique shape, further enhancing the stability of the structure. The wave-shaped side plate can improve its wind pressure resistance. In a strong wind environment, the wave-shaped structure can better adapt to changes in wind force, reducing the risk of structural damage caused by excessive wind force.

[0013] Preferably, the supporting plate is concave downward and has a sunken position, both side walls of the sunken position are inclined towards the bottom wall of the sunken position, the bottom wall of the sunken position is communicated with the drainage groove, and the sewage leaked from the pipeline inside the pipe gallery structure is drained to the drainage groove through the inclined side walls of the sunken position.

[0014] By adopting the technical scheme, the pipe gallery structure can effectively collect and guide the sewage leaked from the pipeline into the drainage groove, avoid the sewage from accumulating or flowing around on the supporting plate, and reduce the influence of the sewage on the surrounding environment. Meanwhile, the design of the sinking position enables the sewage to quickly gather and flow into the drainage groove through the inclined side wall, improving the drainage efficiency and reducing the pollution risk.

[0015] Preferably, the bottom wall of the sinking position is inclined along the extension direction of the sinking position.

[0016] By adopting the technical scheme, the bottom wall of the sinking position is inclined along the extension direction of the sinking position, which can further promote the quick gathering and discharge of the sewage. This design enables the sewage to quickly slide along the inclined bottom wall to the drainage groove after flowing into the sinking position, reduces the residence time of the sewage on the supporting plate, and avoids the secondary pollution risk caused by excessive water accumulation. Meanwhile, the inclined bottom wall also helps to keep the surface of the supporting plate dry, reduces the possibility of corrosion and rust, and prolongs the overall service life of the pipe gallery structure.

[0017] Preferably, the two sides of the sinking position are provided with a plurality of protrusions distributed along the extension direction of the sinking position, and the protrusions extend along the inclined direction of the side wall of the sinking position.

[0018] By adopting the technical scheme, the leaked sewage can be effectively guided to quickly flow into the drainage groove along the side wall of the sinking position, reducing the residence time of the sewage on the supporting plate and the secondary pollution risk caused by the evaporation of the sewage. Meanwhile, the design of the protrusions also enhances the water flow guidance, ensures smooth discharge of the sewage into the drainage groove, and further improves the safety and environmental performance of the pipe gallery structure.

[0019] Preferably, the inner bottom wall of the drainage groove is inclined, and a plurality of partitions are arranged in the drainage groove, the partitions are distributed along the inclined direction of the inner bottom wall of the drainage groove, the distance from the bottom of each partition to the inner bottom wall of the drainage groove is equal, the side of the partition inclined to the upper end of the inner bottom wall of the drainage groove is the water-approaching side, and a water level sensor is arranged on the water-approaching side of each partition. When the water level sensors of the partitions distributed along the inclined direction of the drainage groove are sequentially detected, it is judged that the pipeline inside the pipe gallery structure has a sewage leakage.

[0020] By adopting the technical scheme, each partition is kept a certain distance from the inner bottom wall of the drainage groove, and a water level sensor is installed on the water-approaching side of each partition. When the water in the drainage groove flows along the inclined direction and sequentially triggers the water level sensors on each partition, it can be accurately judged that the pipeline inside the pipe gallery has a sewage leakage. If all the water level sensors are activated at the same time or only part of the sensors are individually sensed, it may be a false alarm caused by rain or a water truck passing by, thereby improving the accuracy of the water leakage detection.

[0021] Preferably, the number of the sinking positions at the supporting plate is not less than two, and the sinking positions are distributed along the width direction of the pipe gallery structure and extend along the length direction of the pipe gallery structure. When the water level sensors in the drainage groove at one of the sinking positions successively detect water accumulation, it is preliminarily judged that the pipeline directly above the sinking position has a sewage leakage.

[0022] By adopting the above technical solutions, the pipe gallery structure can effectively deal with the problem of pipeline leakage. Specifically, by arranging multiple sinking positions and distributing the sinking positions along the width direction of the pipe gallery and extending along the length direction, it can ensure that the sewage in different areas can be collected and diverted into the drainage groove in time, avoiding secondary pollution caused by sewage accumulation. By arranging a plurality of water level sensors in the drainage groove corresponding to each sinking position, when continuous water accumulation occurs in a certain area, the system can quickly determine that the pipeline above the area may have a leakage, so as to quickly locate the fault point, facilitate maintenance personnel to handle the situation in time, and reduce the negative impact on the entire system. The design of multiple sinking positions not only improves the efficiency of sewage collection, but also enhances the reliability and safety of the system, which helps to ensure the cleanliness of the surrounding environment and the safety of residents.

[0023] Preferably, a heat dissipation gap exists between the bottom of the side plate and the framework, and a blocking strip for shielding the heat dissipation gap is arranged at the bottom outside of the framework. The top of the blocking strip is higher than the heat dissipation gap, and a gap exists between the blocking strip and the outside of the side plate.

[0024] By adopting the above technical solutions, the pipe gallery structure can effectively prevent internal pollutants from leaking out while ensuring good ventilation and heat dissipation performance. Specifically, the design of the heat dissipation gap forms an effective air flow channel between the bottom of the side plate and the framework, enhancing the heat dissipation capacity of the pipe gallery interior and helping to reduce the internal temperature and prolong the service life of the equipment. The blocking plate is arranged higher than the heat dissipation gap and has a gap with the outside of the side plate, which can effectively block the internal sewage from leaking to the external environment through the heat dissipation gap, ensuring public safety and environmental hygiene.

[0025] Preferably, the framework, the side plate, the top plate, and the supporting plate are all modular disassembly structures.

[0026] By adopting the above technical solutions, the modular design of the pipe gallery structure is realized, and each component can be conveniently and quickly installed and disassembled. This not only improves the construction efficiency and reduces the maintenance cost, but also eliminates the need to demolish the entire pipe gallery structure when replacing or repairing a certain part, further improving the flexibility and convenience of use.

[0027] In summary, the present application has at least one of the following beneficial technical effects:

[0028] 1. By setting a ventilation opening at the top plate and a baffle covering below the ventilation opening at the top position of the framework, a ventilation gap is formed, which not only realizes good ventilation and heat dissipation performance, but also effectively prevents internal pollutants from leaking out through the ventilation opening, solving the problem that the existing technology cannot balance ventilation and leakage prevention;

[0029] 2. The drainage groove is arranged at the support plate to timely drain the accumulated water on the support plate, avoiding problems such as increased humidity inside the pipe gallery or equipment damage due to excessive accumulated water, and improving the overall safety of the pipe gallery;

[0030] 3. The design of the sinking position enables the sewage to be quickly drained to the drainage groove through the inclined side wall, further enhancing the effect of sewage collection and discharge, reducing the residence time of sewage in the pipe gallery, and reducing the risk of environmental pollution;

[0031] 4. The heat dissipation gap is arranged between the bottom of the side plate and the framework, and the baffle higher than the heat dissipation gap is arranged outside, which can not only increase the air exchange frequency between the inside and outside to improve the heat dissipation efficiency, but also prevent external debris from entering the pipe gallery to maintain the internal cleanliness;

[0032] 5. The framework, side plate, top plate and support plate are all modular disassembly structures, which are convenient for installation and maintenance, and improve the construction efficiency and post-maintenance convenience;

[0033] 6. A plurality of sinking positions are arranged and equipped with water level sensors, when a plurality of water level sensors in the drainage groove of one sinking position detect accumulated water in sequence, it can be preliminarily judged that the pipeline directly above the sinking position has a sewage leakage, so as to realize fault positioning and timely processing.

DETAILED DESCRIPTION

[0040] The following will be described in detail in combination with the accompanying drawings. Figures 1-5 Further detailed description will be made to the present application.

[0041] The embodiment of the present application discloses a pipe gallery structure, referring to Figure 1 and Figure 2 , comprising a skeleton 1, side plates 2 erected on both sides of the skeleton 1, a top plate 3 erected on the top of the skeleton 1, and a supporting plate 4 laid on the bottom of the skeleton 1. A plurality of horizontal support frames 11 are installed on the inner side of the skeleton 1, which are used for supporting and locking the pipelines, and the support frames 11 are provided with a plurality of long hole to facilitate the adjustment of the position of the pipelines. Two ventilation openings 13 are provided on the top plate 3, and two baffles 14 are arranged at the top position in the skeleton 1. The baffles 14 are fixed below the ventilation openings 13 by hangers and cover the corresponding ventilation openings 13 below, and the baffles 14 are inclined downward to both sides and have ventilation gaps with the ventilation openings 13 to allow air to be discharged or rainwater to enter. A drainage groove 5 is arranged at the supporting plate 4 to discharge the accumulated water on the supporting plate 4 and the sewage leaked from the pipelines.

[0042] Specifically, the skeleton 1 is assembled by a plurality of special-shaped component skeletons, which are fixed by bolts to ensure the stability of the whole skeleton. The special-shaped component skeleton is a non-standard part, which is processed by cutting plate, and has good economy and low cost while meeting the force requirement. The material of the skeleton 1 can be high-strength steel or other corrosion-resistant materials to ensure the stability during long-term use. The height of the skeleton 1 can be adjusted according to actual needs, generally 2-3 meters, and the width can be determined according to the number and diameter of the pipelines in the pipe gallery, generally 3-5 meters.

[0043] The top plate 3 is also designed in a modular manner and is assembled by a plurality of wave-shaped unit plates, and each plate is fixed by buckles or bolts. The thickness of the top plate 3 is generally 0.5-1 cm, and the surface is coated with an anti-corrosion coating to prevent rusting caused by long-term exposure to a humid environment.

[0044] The two ventilation openings 13 are arranged on both sides of the top plate 3, and the ventilation openings 13 extend along the length direction of the pipe gallery structure, and the edges of the ventilation openings 13 are provided with reinforcing ribs to enhance the structural strength.

[0045] The baffle plate 14 is installed at the top of the inside of the framework 1, and its height is slightly lower than that of the top plate 3, specifically in the range of 1.8-2.8 meters, so as to facilitate the circulation of ventilation gas. The material of the baffle plate 14 is the same as that of the top plate 3, and has good waterproof and corrosion-resistant properties. The lower edge of the baffle plate 14 is about 10-20 cm away from the ventilation opening 13, forming a certain ventilation gap. In this way, both sufficient ventilation area and blocking effect when sewage leaks are ensured, avoiding direct leakage of sewage through the ventilation opening 13.

[0046] The side plate 2 is of a modular disassembly structure and is arranged in a vertically extending wave shape. The height difference between the wave crest and the wave trough is about 10-20 cm. Such a design enhances the rigidity and stability of the side plate 2. The material of the side plate 2 is the same as that of the top plate 3, and has good waterproof and corrosion-resistant properties. The side plate 2 is clamped and locked at both sides by the buckle positions of the framework 1. A sealing strip 12 is arranged at the gap between the side of the side plate 2 of the framework 1 and the framework 1. The material of the sealing strip 12 can be rubber or silicone, which has good elasticity and sealing performance, effectively preventing internal sewage from seeping out of the pipe gallery structure. The installation position of the sealing strip 12 is close to the contact position of the side plate 2 and the framework 1, ensuring no gap.

[0047] Referring to Figure 3 and Figure 4 , the supporting plate 4 is also of a modular disassembly structure and is sequentially laid at the bottom of the framework 1, having high bearing capacity and compression strength. The thickness of the supporting plate 4 is generally 0.3 mm, and the surface is smooth and flat, facilitating cleaning and maintenance. The supporting plate 4 is downwardly recessed to have two sunken positions 41, which are distributed along the width direction of the pipe gallery structure and extend along the length direction of the pipe gallery structure. The two side walls of the sunken position 41 are inclined toward the bottom wall of the sunken position 41, and the inclination angle is 10°-15°, which is conducive to the rapid drainage of sewage into the drainage groove 5. The bottom wall of the sunken position 41 is inclined along the extension direction of the sunken position 41, and the inclination angle is about 5°, which facilitates smooth drainage of water into the drainage groove 5.

[0048] The two sides of the sunken position 41 are provided with a plurality of protrusions 42 distributed along the extension direction of the sunken position 41, and the protrusions 42 extend along the inclination direction of the side wall of the sunken position 41. The design can effectively guide the leaked sewage to flow quickly into the drainage groove 5 along the side wall of the sunken position 41, reduce the residence time of the sewage on the supporting plate 4, and reduce the risk of secondary pollution caused by evaporation of the sewage. At the same time, the design of the protrusions 42 can also enhance the guiding property of the water flow, ensure smooth drainage of the sewage into the drainage groove 5, and further improve the safety and environmental performance of the pipe gallery structure.

[0049] The drainage groove 5 is arranged in the sunken position 41 of the supporting plate 4, and the inner bottom wall of the drainage groove 5 is arranged to be inclined, with an inclination angle of about 5-10°, so as to facilitate smooth drainage of water flow. A plurality of partitions 51 are arranged in the drainage groove 5, and the partitions 51 are distributed along the inclined direction of the inner bottom wall of the drainage groove 5, with a general interval of 50-100 cm, so as to form a plurality of compartments. The compartment located at the lower end of the inclined bottom wall of the drainage groove 5 is connected with a drainage pipe, so as to drain the accumulated water. The distance from the bottom of the partition 51 to the inner bottom wall of the drainage groove 5 is equal, and the accumulated water can pass through the gap between the bottom wall of the drainage groove 5 and the bottom of the partition 51. When pipeline sewage leakage occurs, the amount of accumulated water is usually large, and the gap cannot meet the water flow. Therefore, the previous compartment overflows, and then overflows from the upper end of the partition 51 to the next compartment.

[0050] In the embodiment, the water side of the partition 51 is provided with a water level sensor. When the water level sensors of the plurality of partitions 51 distributed along the inclined direction of the drainage groove 5 detect accumulated water in sequence, it is judged that the pipeline in the pipe gallery structure has a sewage leakage. If all the water level sensors are activated at the same time or only part of the sensors are individually sensed, it may be a false alarm caused by rain or a water truck passing by, thereby improving the accuracy of the water leakage detection.

[0051] In other embodiments, the supporting plate 4 is provided with a plurality of sunken positions 41, and the number of drainage grooves 5 connected with each sunken position 41 is also not less than 2. A plurality of drainage grooves 5 are distributed along the extension direction of the sunken position 41. When the water level sensors in one of the drainage grooves 5 of one of the sunken positions 41 detect accumulated water in sequence, it is preliminarily judged that the pipeline in the range of the drainage groove 5 has a sewage leakage. That is, when there is continuous accumulated water in a certain area, the system can quickly judge that the pipeline above the area may have a leakage, so as to quickly locate the fault point, facilitate maintenance personnel to use the maintenance robot to handle in time, and reduce the negative impact on the entire system. The design of the plurality of sunken positions 41 and the plurality of drainage grooves 5 not only improves the efficiency of sewage collection, but also enhances the reliability and safety of the system, which is helpful to protect the surrounding environment and the safety of residents.

[0052] Referring to Figure 5 In the embodiment, there is a heat dissipation gap 6 between the bottom of the side plate 2 and the framework 1 for air exchange between the inside and outside, and the height is generally 5-10 cm. The bottom of the outer side of the framework 1 is provided with a blocking strip 15 for shielding the heat dissipation gap 6. The top of the blocking strip 15 is higher than the heat dissipation gap 6 between the bottom of the side plate 2 and the framework 1, and the distance is about 10-20 cm. There is a gap 7 between the blocking plate 14 and the outer side of the side plate 2, forming a natural ventilation channel.

[0053] In this embodiment, the modular disassembly structure is designed to facilitate the assembly and disassembly of the entire pipe gallery structure, making it convenient for later maintenance and replacement. Each component is clearly labeled for quick identification and installation by on-site construction personnel.

[0054] The implementation principle of this embodiment is:

[0055] Through the optimization design of the pipe gallery structure, good ventilation and heat dissipation performance and leakage prevention function are achieved. The combination design of the ventilation opening 13 and the baffle 14 not only ensures the effective circulation of air, but also plays a barrier role when sewage leaks. The design of the sunken position 41 under the supporting plate 4 and the drainage groove 5 can quickly collect and drain the leaked sewage, avoiding the spread of pollution. The wavy design of the side plate 2 and the use of the sealing strip 12 enhance the stability and airtightness of the structure. The existence of the heat dissipation gap 6 further realizes the circulation of air, improves the operation efficiency and service life of the equipment. Overall, this pipe gallery structure effectively solves the problems of high temperature and leakage in traditional design, and improves the safety and environmental protection of urban infrastructure.

[0056] The above are preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, any equivalent changes made in terms of structure, shape, and principle based on the present application should be covered within the protection scope of the present application.
