Description

Technical Field

[0001] This utility model relates to the field of water supply and drainage pipeline laying technology, specifically to a modular base plate for water supply and drainage pipelines that can be continuously laid. Background Technology

[0002] The construction of municipal water supply pipelines is mainly carried out in accordance with the GB50268 standard. This standard has detailed and clear implementation requirements for key construction aspects such as trench backfilling. This technical specification is essential to ensure the construction quality and subsequent operational safety of water supply pipeline projects. It comprehensively regulates technical standards for trench excavation dimensions, slope control, trench bottom treatment, as well as the selection and compaction of backfill materials, providing important technical guidance for the construction of municipal water supply pipelines.

[0003] Although GB50268 is a reference in actual production, construction quality control issues often arise, such as non-standard trench excavation and backfilling; pipeline leakage caused by road subsidence; and construction errors caused by municipal departments' rigid requirements for traffic restoration during construction and nighttime construction measures. Summary of the Invention

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a modular base plate for water supply and drainage pipelines that can be continuously laid. This is to solve problems such as non-standard trench excavation and backfilling, pipeline interface leakage caused by road settlement, the rigidity of traffic restoration by municipal departments during construction, and construction errors that are easily generated by nighttime construction measures.

[0005] To achieve the above objectives, this utility model designs a modular base plate for continuously installed water supply and drainage pipelines. The modular base plate is used to be installed on a trench to form a foundation for pipeline installation. The modular base plate is connected to the pipeline by binding.

[0006] The modular base plate has an upper step structure and a lower step structure on its left and right sides, respectively. The upper step structure and the lower step structure are respectively provided with matching protrusions and grooves so that two adjacent modular base plates can be laid and connected together.

[0007] The modular base plate has a square support in the middle, which includes multiple arrays of hollow structures. The lower surface of the square support is on the same plane as the lower surface of the modular base plate.

[0008] The square support is provided with pipe support on both the left and right sides. The pipe support includes a first side plate and a second side plate. The first side plate and the second side plate form a hollow area. A first inclined plate and a second inclined plate are provided in the hollow area. One end of the first inclined plate and the second inclined plate are connected to the middle of the first side plate. The other end of the first inclined plate and the second inclined plate are connected to both ends of the second inclined plate, respectively. The middle of the first side plate, the second side plate, the first inclined plate and the second inclined plate is a downwardly recessed trapezoidal structure, which is used to jointly support the pipe.

[0009] Preferably, the modular base plate has a first side and a second side, the first side and the second side have the same structure, including a plurality of cylindrical hollow structures and grooves.

[0010] The first and second side edges each have two notches at their lower edges for use with self-locking straps to secure the pipe.

[0011] Compared with the prior art, the advantages of this utility model are:

[0012] This utility model utilizes an overlapping modular base plate to meet the requirements of pipeline laying. The hollow design of the base plate not only makes it lightweight but also facilitates soil collection and stabilization during trench backfilling. The modular construction technology allows for easy overlapping of the modular base plate structure, enabling rapid leveling and the formation of a continuous trench foundation for convenient pipeline laying. After pipeline laying, the base plate is secured to the pipeline body and the base plate using strapping, resulting in a more stable modular base plate. The modular base plate and pipeline structure work together to enhance the resistance to disturbance at the pipeline interfaces and the overall stability of the pipeline structure, thereby reducing the risk of leakage.

[0021] refer to Figures 1-6 This utility model discloses a modular base plate for continuously paved water supply and drainage pipes. The modular base plate 1 has an upper stepped structure on the left and a lower stepped structure on the right. The upper half of the left side of the modular base plate 1 extends outward to form an upper stepped structure with the lower half. The upper and lower halves of the upper stepped structure are provided with three protrusions and two grooves. The two protrusions on the left and right sides of the upper half are the first protrusions 2, and the upper surface of the first protrusions 2 has a notch. The two protrusions on the left and right sides of the lower half are the second protrusions 3, and the protrusion in the middle between the upper and lower halves is the third protrusion 4. The first protrusions 2, the second protrusions 3, and the third protrusions 4 are all rectangular structures. The lower half of the right side of the modular base plate 1 extends to the side to form a lower stepped structure. The upper half of the lower stepped structure is provided with two trapezoidal protrusions. The hypotenuse of the trapezoidal protrusions cooperates with other structures to support the pipe. The lower half has an outwardly protruding groove structure on the side. The stepped structures on the left and right sides of the modular base plate 1 are arranged in a coordinated manner to allow adjacent base plates to partially overlap and be spliced.

[0022] The modular base plate 1 has a square support part 5 in the middle, which is a 3×3 hollow structure. The lower surface of the square support part 5 is on the same plane as the lower surface of the modular base plate 1. Pipe support parts 6 are provided on the left and right sides of the square support part 5. The pipe support part 6 includes a first side plate 7 and a second side plate 8. The first side plate 7 and the second side plate 8 form a hollow area. A first inclined plate 9 and a second inclined plate 10 are provided in the hollow area. One end of the first inclined plate 9 and the second inclined plate 10 are connected to the middle of the first side plate 7, and the other end of the first inclined plate 9 and the second inclined plate 10 are connected to the two ends of the second side plate 10, respectively. The middle of the first side plate 7, the second side plate 8, the first inclined plate 9 and the second inclined plate 10 is a downwardly recessed trapezoidal structure, which is used to jointly support the pipe.

The middle part of the first side 11 includes four cylindrical hollow structures, and each cylindrical hollow structure is connected by a groove on the first side 11. The lower edges of the first side 11 and the second side 12 are each provided with two notches 13 for use with self-locking straps to fix the pipes.

[0024] In use, the modular base plate 1 can be overlapped along the longitudinal direction of the pipeline according to actual needs, and installed on the trench to form the foundation for pipeline installation. It is used in conjunction with self-locking cable ties to fix the pipeline to the base plate. The self-locking cable ties should be made of materials that are not easy to age or decay, are lightweight, safe and non-toxic, easy to use, have high tensile strength and are wear-resistant. Cable ties can be divided into plastic cable ties, stainless steel cable ties, powder-coated stainless steel cable ties, etc. according to their materials.
