As shown in fig. 1 and 2 in the prior art, the conveying pipeline unit 20 in the pipe rack main body 10 is a plurality of single conveying pipelines arranged in the horizontal direction, and the space above the conveying pipeline unit 20 in the pipe rack main body 10 is not effectively utilized, so that the space in the pipe rack main body 10 is wasted. According to the pipe gallery pipeline arrangement structure, the plurality of conveying pipelines are arranged in the vertical direction, so that the space inside the pipe gallery main body 10 is fully utilized, the required section size of the pipe gallery main body 10 is reduced compared with the arrangement mode of the conveying pipelines in the prior art, the operation and maintenance space of a pipe gallery is increased, the pipe gallery is convenient to construct and operate by engineering maintenance personnel, the engineering operation management difficulty is reduced, the engineering cost is saved while the engineering quality is ensured, and the pipe gallery pipeline arrangement structure has obvious environmental protection benefits and economic benefits.
In an embodiment of the present invention, the pipe rack main body 10 is a comprehensive pipe rack with a slope, the conveying pipeline is a high-pressure water conveying pipeline, the high-pressure water conveying pipeline needs to be exposed in the pipe rack main body 10, the water flow direction in the high-pressure water conveying pipeline flows from a low position to a high position, and the slope is determined according to the overall arrangement of the actual engineering project.
It will be appreciated that in order to further make efficient use of the space within the tube lane body 10, the tube lane pipe arrangement may include a plurality of sets of transport pipe units 20 that are parallel and horizontally spaced from each other. Different delivery piping units 20 may be provided as different piping facilities such as municipal utility piping for supply water, rainwater, reclaimed water, sewage, heat, power, communication, etc. to meet the needs of production and living.
In particular, the pipe gallery piping arrangement comprises a plurality of ballast blocks 33 for supporting the conveying pipe unit 20, the ballast blocks 33 being arranged to surround and envelop the conveying pipe unit 20. As a preferred embodiment, the piers may be added at regular intervals to fulfill the functions of the normal operation of the conveying pipe unit 20, thereby optimizing the pipe layout. Wherein, the anchor blocks 33 can adopt a cast-in-place concrete structure.
In a preferred embodiment of the invention, the conveying pipe unit 20 comprises a first conveying pipe 21 and a second conveying pipe 22 located above the first conveying pipe 21, the pipe gallery pipe arrangement comprises a first abutment 31 located at the bottom inside the pipe gallery body 10, the first abutment 31 is used for supporting the first conveying pipe 21, and a plurality of the first abutments 31 are arranged between adjacent ones of the abutments 33. Further, the pipe gallery pipe arrangement structure comprises a second buttress 32 located at the bottom of the inner side of the pipe gallery main body 10, wherein the second buttress 32 is used for supporting the second conveying pipe 22, and a plurality of second buttresses 32 are arranged between the adjacent piers 33. Further, the first piers 31 and the second piers 32 are alternately arranged, and the number of the first piers 31 and the second piers 32 between the adjacent piers 33 is equal. Wherein, the distance between two adjacent first piers 31 is determined according to engineering practical arrangement and pipeline structure calculation, and is generally between 6m and 10 m. The thickness of the buttress is combined, the construction requirement between the adjacent first buttress 31 and the second buttress 32 is met, and the distance between the adjacent first buttress 31 and the adjacent second buttress 32 is generally between 1m and 2 m. It is understood that a plurality of conveying pipelines can be provided in the present invention, which is not limited to the first conveying pipeline 21 and the second conveying pipeline 22, and the number of the conveying pipelines is increased, and the number of the piers is correspondingly increased. Preferably, the first pier 31 and the second pier 32 may be constructed of cast-in-place concrete.
In addition, as shown in fig. 3, the second buttress 32 is internally provided with a hole for the first delivery pipe 21 to pass through, the inner side of the hole is provided with a sleeve 35, and the inner diameter of the sleeve 35 is larger than the outer diameter of the first delivery pipe 21. The sleeve 35 may be used as a template for casting the second buttress 32, and the sleeve 35 may be a steel pipe, a PE pipe, or a hard pipe made of other materials. The inner diameter of the sleeve 35 is larger than the outer diameter of the first conveying pipeline 21, so that even if the first conveying pipeline 21 passes through the sleeve, the requirement of the first conveying pipeline 21 on stretching deformation is met, and mutual interference influence among the pipelines is ensured.
Further, a thrust ring 23 is formed on the outer circumferential surface of the delivery pipe unit 20, and the ballast 33 is poured around and wraps the portion of the delivery pipe unit 20 where the thrust ring 23 is provided to restrict the axial movement of the delivery pipe unit 20.
