Abstract
Description
Technical Field
[0001] This utility model relates to the field of valve chamber construction technology, specifically to a valve chamber structure with waterproof and seepage-proof functions for long-distance pipelines. Background Technology
[0002] Long-distance pipelines, as crucial infrastructure for energy transportation, play a vital role in fields such as oil and natural gas. Valve chambers, as an important component of long-distance pipeline systems, undertake important functions such as controlling the flow and pressure of fluids in the pipeline, and shutting off the pipeline in emergencies. The rationality and safety of their structure directly affect the stable operation of the entire long-distance pipeline system.
[0003] Waterproofing and seepage prevention have always been major challenges for valve chambers in long-distance pipelines. Traditional valve chambers suffer from poor waterproofing and seepage prevention due to design deficiencies, especially when located underground, where groundwater continuously exerts upward pressure on the structure. Some traditional valve chamber structures lack effective waterproofing measures, allowing groundwater to easily penetrate and corrode the equipment and pipelines inside. Once corroded, the performance and lifespan of this equipment and pipelines are significantly reduced, increasing maintenance costs and potentially causing equipment failures, thus affecting the normal operation of the long-distance pipeline. Utility Model Content
[0004] The purpose of this utility model is to provide a valve chamber structure for long-distance pipelines with waterproof and seepage-proof functions that is structurally stable, has a wide range of applications, and can improve safety.
[0005] A valve chamber structure with waterproof and seepage-proof function for long-distance pipelines includes a support mechanism, a valve chamber body, and a pipeline body. The support mechanism includes several columns and a concrete base plate fixed to the columns. The columns surround the outer periphery of the valve chamber body and are fixed to the valve chamber body. The concrete base plate is fixed to the lower surface of the valve chamber body. The area of the concrete base plate is the same as the floor area of the valve chamber body. The pipeline body is buried below the concrete base plate.
[0006] In the above design, the columns are installed around the outer perimeter of the valve chamber and fixedly connected to it, effectively creating a robust lateral protection frame that resists lateral forces from all directions, such as wind and earthquakes. The concrete substrate acts as an isolation layer, effectively preventing groundwater infiltration. Furthermore, the concrete substrate itself has a certain degree of waterproofing, and its dense structure reduces water penetration, significantly lowering the risk of groundwater seeping into the valve chamber. This also enhances the safety of operators entering the valve chamber to manipulate the pipeline embedded beneath the concrete base. This valve chamber design is suitable for various geological conditions and environments, especially in areas with high groundwater levels or abundant rainfall, effectively preventing water from seeping into the valve chamber and ensuring the normal operation of long-distance pipeline systems.
[0007] Furthermore, the concrete substrate is filled with backfill sand or stone powder.
[0008] In the above scheme, part of the valve chamber is built underground, which requires excavating the underground soil. After the columns are built, backfill sand or stone powder needs to be filled at appropriate locations and heights to facilitate the construction of the concrete base plate. The backfill sand and stone powder themselves have a certain strength and bearing capacity. When filled under the concrete base plate, they can share the upper load with the foundation soil, thereby improving the bearing capacity of the entire foundation. In addition, the backfill sand and stone powder have good permeability, which can quickly drain infiltrated groundwater or rainwater. In areas with high groundwater levels or heavy rainfall, timely drainage can prevent the foundation soil from softening due to long-term immersion in water. At the same time, it can also reduce the erosion of water on the concrete base plate and columns, and extend the service life of the valve chamber structure.
[0009] Furthermore, the valve chamber body includes a floor layer and a wall structure, the floor layer is laid on the concrete substrate, and the wall structure is fixedly connected to the column.
[0010] In the above scheme, the concrete substrate is cast in concrete, and the floor layer is laid on top of the concrete substrate, further enhancing the barrier effect against groundwater. Even if the concrete substrate develops minor cracks or leaks, the floor layer can act as a second line of defense, preventing groundwater from seeping into the valve chamber. The floor layer can be laid using materials with excellent waterproof properties, such as waterproof concrete or waterproof membrane, effectively preventing moisture intrusion and protecting the equipment and pipelines inside the valve chamber from groundwater corrosion.
[0011] Furthermore, the wall structure of the valve chamber body is made of concrete below ground level and brick above ground level.
[0012] In the above-mentioned scheme, the underground environment is relatively complex. The soil usually contains a certain amount of moisture, and groundwater may also exert seepage pressure on the walls. The concrete structure has good integrity and density, which can effectively block the seepage of groundwater. The part above ground is less affected by groundwater, but may be affected by rainwater erosion and air humidity. The brick structure has a certain degree of breathability, which can allow moisture inside the wall to dissipate and reduce indoor dampness.
[0013] Furthermore, it also includes a valve, which is located above the floor layer, and the pipe body is connected to the valve via a connector.
[0014] In the above solution, the valves are installed above the floor level, allowing operators easy access to open, close, and adjust them, thus improving work efficiency. For example, during routine inspections and maintenance, staff can quickly reach the valves and handle various situations promptly.
[0015] Furthermore, a lower padding layer is connected to the lower part of the column.
[0016] In the above scheme, the columns mainly bear the weight of the upper structure of the valve chamber, including the pressure generated by the roof, equipment, etc. The lower cushion layer can distribute the concentrated load from the columns to a larger area of the foundation. Without the lower cushion layer, the pressure of the columns on the foundation will be concentrated on a small contact surface, which can easily cause the foundation to be subjected to excessive pressure locally and settle. With the lower cushion layer, the pressure is distributed, reducing the risk of local foundation failure, ensuring the overall stability of the valve chamber structure, and also achieving waterproofing and seepage prevention to a certain extent.
[0017] Furthermore, the column includes a pier section and a column body section, which are integrally cast from concrete.
[0018] In the above scheme, when the concrete is poured as a whole, the concrete of the pier and the column works together to form a whole with uniform strength and stiffness. Compared with columns constructed by assembly or segmented construction and then spliced, the columns formed in one piece do not have the problem of stress concentration at the splice. This allows the mechanical properties of concrete materials to be fully utilized, and improves the column's compressive, bending and shear resistance. This enables the column to withstand greater loads and is suitable for buildings with high requirements for structural bearing capacity.
[0019] Furthermore, the valve chamber body is provided with a platform, an upper staircase and a lower staircase, the platform is connected to the upper staircase and the lower staircase, and the steps of the upper staircase and the lower staircase are provided with anti-slip strips.
[0020] In the above scheme, due to the overall height of the valve chamber, two sets of stairs, an upper staircase and a lower staircase, are required. The anti-slip strips greatly increase the friction of the step surface, which can effectively prevent people from slipping when going up and down the stairs. When workers are carrying out daily inspections or maintenance work, even if the soles of their shoes are contaminated with water or other substances, the anti-slip strips can still provide sufficient friction to ensure their walking safety and reduce the occurrence of accidents such as falls and sprains caused by slipping.
[0021] This utility model discloses a valve chamber structure for long-distance pipelines with waterproof and seepage-proof functions, which has the advantages of structural stability, wide applicability, and improved safety. The columns are installed around the outer perimeter of the valve chamber body and fixedly connected to it, essentially constructing a robust lateral protection frame for the valve chamber body. This effectively resists lateral forces from all directions, such as wind and earthquake forces. The concrete substrate acts as an isolation layer, effectively preventing groundwater infiltration. Furthermore, the concrete substrate itself has a certain degree of waterproofing, and its dense structure reduces water penetration, effectively lowering the risk of groundwater seeping into the valve chamber body. This also enhances the safety of operators entering the valve chamber body to manipulate the pipeline body buried beneath the concrete base. This valve chamber design is suitable for various geological conditions and environments, especially in areas with high groundwater levels or abundant rainfall, effectively preventing water from seeping into the valve chamber body and ensuring the normal operation of the long-distance pipeline system.

[0027] The following will describe in further detail a valve chamber structure with waterproof and seepage-proof functions for long-distance pipelines according to the present invention, in conjunction with specific embodiments and accompanying drawings.
[0028] like Figures 1 to 4 As shown in a preferred embodiment, a valve chamber structure with waterproof and seepage-proof functions for long-distance pipelines includes a support mechanism 2, a valve chamber body 1, and a pipeline body 3. The support mechanism 2 includes several columns 21 and a concrete base plate 22 fixedly connected to the columns 21. The columns 21 surround the outer periphery of the valve chamber body 1 and are fixedly connected to the valve chamber body 1. The concrete base plate 22 is fixedly connected to the lower surface of the valve chamber body 1, and the area of the concrete base plate 22 is the same as the floor area of the valve chamber body 1. The pipeline body 3 is buried below the concrete base plate 22. The columns 21 surrounding the outer periphery of the valve chamber body 1 and being fixedly connected to the valve chamber body 1 are equivalent to constructing a robust lateral protection frame for the valve chamber body 1, which can effectively resist lateral forces from various directions, such as wind and earthquake forces.
[0029] To prevent instability or floating of the valve chamber structure due to excessive buoyancy of groundwater, the thickness of the concrete base plate 22 and the overall structure of the valve chamber require anti-buoyancy calculations. The concrete base plate 22 acts as an isolation layer, effectively preventing groundwater infiltration. Furthermore, the concrete base plate 22 itself has a certain degree of waterproofing, and its dense structure reduces water penetration, effectively lowering the risk of groundwater seeping into the valve chamber body 1. This enhances the safety for operators entering the valve chamber body 1 to manipulate the pipeline body 3 buried beneath the concrete base. This valve chamber design is suitable for various geological conditions and environments, especially in areas with high groundwater levels or abundant rainfall, effectively preventing water from seeping into the valve chamber body 1 and ensuring the normal operation of the long-distance pipeline system.
[0030] Furthermore, the concrete base plate 22 is fixedly connected to the lower surface of the valve chamber body 1, and its area is consistent with the floor area of the valve chamber body 1. This design allows the weight of the valve chamber body 1 to be evenly transferred to the concrete base plate 22, which then distributes the load into the foundation. Compared to a smaller supporting structure, the large-area concrete base plate 22 reduces the pressure on the foundation per unit area, preventing uneven settlement of the foundation due to excessive local pressure, thereby ensuring the stability of the valve chamber.
[0031] like Figure 2 and Figure 3 As shown, in some embodiments, the concrete substrate 22 is filled with backfill sand or stone powder.
[0032] In the above scheme, part of the valve chamber is built underground, which requires excavating the underground soil. After the column 21 is constructed, backfill sand or stone powder needs to be filled at a suitable location and height to facilitate the construction of the concrete base plate 22. The backfill sand and stone powder themselves have a certain strength and bearing capacity. When filled under the concrete base plate 22, they can share the upper load with the foundation soil, thereby improving the bearing capacity of the entire foundation. In addition, the backfill sand and stone powder have good permeability, which can quickly drain infiltrated groundwater or rainwater. In areas with high groundwater levels or heavy rainfall, timely drainage can prevent the foundation soil from softening due to long-term immersion in water. At the same time, it can also reduce the erosion of water on the concrete base plate 22 and column 21, and extend the service life of the valve chamber structure.
[0033] like Figures 1 to 3 As shown, in some embodiments, the valve chamber body 1 includes a floor layer 11 and a wall structure 12. The floor layer 11 is laid on the concrete substrate 22, and the wall structure 12 is fixedly connected to the column 21. The concrete substrate 22 is cast in concrete, and the floor layer 11 laid on the concrete substrate 22 further enhances the barrier effect against groundwater. Even if the concrete substrate 22 has minor cracks or leaks, the floor layer 11 can act as a second line of defense, preventing groundwater from seeping into the valve chamber body 1. The floor layer 11 can be laid with materials with good waterproof performance, such as waterproof concrete or waterproof membrane, effectively preventing moisture intrusion and protecting the equipment and pipelines inside the valve chamber body 1 from corrosion by groundwater.
[0034] Such as 2 and Figure 3 As shown, in some embodiments, the wall structure 12 of the valve chamber body 1 is constructed of concrete below ground level and brick above ground level. The underground environment is complex; the soil typically contains a certain amount of moisture, and groundwater may exert seepage pressure on the wall structure 12. Concrete structures offer good integrity and density, effectively preventing groundwater infiltration. The portion above ground level is less affected by groundwater but may be affected by rainwater runoff and air humidity. Brick structures provide some breathability, allowing moisture inside the wall structure 12 to dissipate, reducing indoor dampness.
[0035] In the above embodiments, during the pouring process, concrete can form a dense structure by using reasonable mix design and vibration technology, thereby reducing porosity and improving waterproof performance. For example, waterproof concrete with added waterproofing agent can further enhance its impermeability, prevent groundwater from intruding into the valve chamber, and protect the equipment and pipelines in the valve chamber body 1 from water erosion.
[0036] like Figure 2 and Figure 3As shown, in some embodiments, a valve 4 is also included, located above the floor slab, and the pipe body 3 is connected to the valve 4 via a connector 5. Positioning the valve 4 above the floor slab allows operators easy access for opening, closing, and adjustment, improving work efficiency. For example, during routine inspections and maintenance, staff can quickly reach the valve 4 and promptly address various situations.
[0037] like Figure 3 As shown, in some embodiments, a lower cushion layer 6 is connected to the lower part of the column 21. The column 21 mainly bears the weight of the upper structure of the valve chamber, including the pressure generated by the roof, equipment, etc. The lower cushion layer 6 can distribute the concentrated load from the column 21 to a larger area of the foundation. Without the lower cushion layer 6, the pressure of the column 21 on the foundation would be concentrated on a small contact surface, which could easily cause the foundation to be subjected to excessive pressure locally and settle. With the lower cushion layer 6, the pressure is distributed, reducing the risk of local foundation damage, ensuring the overall stability of the valve chamber structure, and also achieving waterproofing and seepage prevention to a certain extent.
[0038] like Figure 3 As shown, in some embodiments, the column 21 includes a pier portion 211 and a column portion 212, which are integrally cast from concrete. During integral concrete casting, the concrete of the pier portion 211 and the column portion 212 combine and work together to form a whole with uniform strength and stiffness distribution. Compared with columns 21 constructed by assembly or segmented construction, the integrally cast column 21 does not have the problem of stress concentration at the joints, and can more fully utilize the mechanical properties of concrete materials, improving the compressive, bending and shear resistance of the column 21. This allows the column 21 to withstand greater loads and is suitable for buildings with high structural bearing capacity requirements.
[0039] like Figure 2 and Figure 3 As shown, in some embodiments, the valve chamber body 1 is provided with a platform 8, an upper staircase 7, and a lower staircase 9. The platform 8 is connected to the upper staircase 7 and the lower staircase 9, and anti-slip strips are provided on the steps of both the upper staircase 7 and the lower staircase 9. Due to the overall height of the valve chamber, two staircases, the upper staircase 7 and the lower staircase 9, are required. The anti-slip strips greatly increase the friction of the step surface, effectively preventing personnel from slipping when going up and down the stairs. When staff are performing routine inspections or maintenance, even if the soles of their shoes are wet or have other substances on them, the anti-slip strips can provide sufficient friction to ensure their walking safety and reduce accidents such as falls and sprains caused by slipping.
[0040] This utility model discloses the working principle and process of a valve chamber structure with waterproof and seepage-proof functions for long-distance pipelines. The column 21 is constructed by concrete pouring, and then backfilled with sand or stone powder to a certain level. After the backfill sand or stone powder is flattened, a concrete base plate 22 is poured. The area of the concrete base plate 22 is consistent with the area occupied by the valve chamber body 1. The concrete base plate 22 acts as an isolation layer, which can effectively prevent the seepage of groundwater. Moreover, the concrete base plate 22 itself has a certain waterproof performance, and its dense structure can reduce water penetration, effectively reducing the risk of groundwater seeping into the valve chamber body 1.
