Description

Technical Field

[0001] The utility model belongs to the technical field of construction engineering, and particularly relates to an underground pipeline intersection structure. Background Technique

[0002] It is pointed out in the Outdoor Drainage Design Code GB50014 that the drainage system should preferably adopt the separate system, that is, rainwater and sewage are discharged through two systems, and their respective pipelines and inspection wells are set separately without mixing with each other. To meet this requirement, the current practice is to increase the covering thickness of the drainage pipeline, and make the rainwater drainage pipe and the sewage drainage pipe at different burial depths, so that the two pipelines are staggered in elevation, so as to avoid pipeline crossing and collision and avoid mixing between rainwater and sewage. Although this practice can meet the needs of the design code, during the planning and design of municipal pipelines, it is impossible to ensure that all the pipelines buried underground are accurately and completely surveyed. Therefore, during the construction of municipal pipelines, it is common to encounter the situation where the elevation of the municipal pipeline conflicts with and intersects with the original underground buried sewage pipe, cable pipeline or rainwater pipe. If the design is changed, it will lead to an increase in the amount of earth excavation and an increase in cost.

[0003] In the prior art, the patent document with the publication number of "CN214574484U" discloses a construction structure for the intersection space of rainwater and sewage pipes at the same elevation, including a rainwater pipeline, a sewage pipeline and an intersection inspection well. The intersection inspection well includes an inspection well entrance arranged at the top of the inner well, a manhole cover covering the inspection well entrance, an outer well, an inner well, and an inner-outer well passage arranged on the well wall of the inner well; the inner well is accommodated in the outer well so as to form an annular cavity for rainwater to flow between the inner well and the outer well; the sewage pipeline penetrates through the outer well and is connected with the inner well, and the rainwater pipeline is connected with the outer well. This patented technology avoids the need to temporarily change the pipeline planning and design during the construction process by setting up an intersection inspection well, which can greatly reduce the construction cost and improve the construction efficiency. However, during the construction of municipal pipelines when pipeline intersections are encountered, since the originally buried underground pipelines have been in use for a certain period of time, the outer surfaces of some existing pipelines have begun to show damage, and it is extremely easy to damage the outer surfaces of the existing pipelines during the construction process of setting up the intersection well. Moreover, after the intersection well is built, the existing pipelines need to be used while being soaked in the water in the intersection well for a long time, which will also damage the existing pipelines, affect the subsequent normal use and service life of the existing pipelines, and pose a greater potential safety hazard. Content of the Utility Model

[0004] To solve the above technical problems, the utility model provides an underground pipeline intersection structure.

[0005] The utility model is realized through the following technical solutions.

[0006] The utility model provides an underground pipeline intersection structure, which includes an intersection well, a first hoop and a second hoop. The two sides of the intersection well are respectively communicated with a first pipe section and a second pipe section. A through pipe is further arranged in the intersection well. The left and right ends of the first hoop are respectively fixedly connected with the left and right ends of the second hoop, and the through pipe is clamped between the first hoop and the second hoop. A protective rubber pad is also clamped between the first hoop and the through pipe and between the second hoop and the through pipe.

[0007] Positioning holes are respectively arranged at the left and right ends of the first hoop. The left and right ends of the second hoop are respectively welded and fixedly connected with one end of a pin rod, and the other end of the pin rod is screwed with a locking nut. When the left and right ends of the first hoop are respectively fixedly connected with the left and right ends of the second hoop, the pin rod is sleeved in the corresponding positioning hole.

[0008] There are multiple pairs of the first hoop and the second hoop, and the multiple pairs of the first hoop and the second hoop are arranged at equal intervals along the length direction of the through pipe.

[0009] The number of the first hoop and the second hoop is more than 3 pairs.

[0010] The overall shape of the protective rubber pad is a semi-cylindrical body.

[0011] The number of the protective rubber pads is one pair.

[0012] At least one end of the first pipe section or the second pipe section is flush with the inner surface of the intersection well.

[0013] The overall shape of the intersection well is a rectangular cylinder.

[0014] The intersection well is formed by concrete casting.

[0015] The beneficial effects of the utility model are as follows: By adopting the technical scheme of the utility model, when pipeline intersections are encountered during the construction of municipal pipelines, the protective rubber pad is used to wrap the existing buried underground pipelines. On the one hand, the protective rubber pad is wrapped on the outer surface of the existing pipeline through the first hoop and the second hoop, enhancing the strength and stiffness of the existing pipeline itself, which is beneficial to extending the service life of the existing pipeline; on the other hand, the protective rubber pad shields the outer surface of the existing pipeline, preventing rainwater or sewage from penetrating into the interior of the existing pipeline, improving the sealing performance of the existing pipeline, reducing the potential safety hazards of the existing pipeline. The protective rubber pad is preferably made of rubber material and can be immersed in water for a long time, avoiding various adverse effects caused by the immersion water on the existing pipeline and extending the service life of the existing pipeline.

[0019] The technical solution of the present utility model will be further described below, but the scope of protection claimed is not limited thereto.

[0020] As Figures 1 to 2 shown, the present utility model provides an underground pipeline intersection structure, including an intersection well 1, a first hoop 2 and a second hoop 3. The two sides of the intersection well 1 are respectively communicated with a first pipe section 4 and a second pipe section 5. A through pipe 6 is also provided in the intersection well 1. The left and right ends of the first hoop 2 are respectively fixedly connected to the left and right ends of the second hoop 3, and the through pipe 6 is clamped between the first hoop 2 and the second hoop 3. A protective rubber pad 7 is also clamped between the first hoop 2 and the through pipe 6 and between the second hoop 3 and the through pipe 6.

[0021] Adopting the technical solution of the present utility model, when pipeline intersections are encountered during the construction of municipal pipelines, the protective rubber pad is used to wrap the existing buried underground pipelines. On the one hand, the protective rubber pad is wrapped on the outer surface of the existing pipeline through the first hoop and the second hoop, enhancing the strength and stiffness of the existing pipeline itself and being beneficial to extending the service life of the existing pipeline. On the other hand, the protective rubber pad shields the outer surface of the existing pipeline, preventing rainwater or sewage from penetrating into the interior of the existing pipeline, improving the sealing performance of the existing pipeline, reducing the potential safety hazards of the existing pipeline. The protective rubber pad is preferably made of rubber material and can be immersed in water for a long time, avoiding various adverse effects caused by the immersion water on the existing pipeline and extending the service life of the existing pipeline.

[0022] Specifically, positioning holes are respectively provided at the left and right ends of the first hoop 2. The left and right ends of the second hoop 3 are respectively welded and fixed to one end of the pin rod 8, and the other end of the pin rod 8 is screwed with a lock nut 9. When the left and right ends of the first hoop 2 are fixedly connected to the left and right ends of the second hoop 3 respectively, the pin rod 8 is sleeved in the corresponding positioning holes. Preferably, the number of the first hoops 2 and the second hoops 3 is multiple pairs, and the multiple pairs of the first hoops 2 and the second hoops 3 are arranged at equal intervals along the length direction of the through pipe 6. The number of the first hoops 2 and the second hoops 3 is more than 3 pairs. The protective rubber pad 7 is in an overall semi-cylindrical shape. The number of the protective rubber pads 7 is one pair. By adopting the technical scheme of the utility model, the first hoop 2, the second hoop 3, the pin rod 8 and the lock nut 9 are all made of stainless steel materials, ensuring that they can be immersed in water for a long time. The protective rubber pad 7 is clamped by using the first hoop 2 and the second hoop 3, and the clamping operation is convenient and fast, so that the protective rubber pad 7 completely covers the surface of the existing pipeline, providing comprehensive protection for it, avoiding water leakage into the interior of the existing pipeline and also avoiding water corrosion on the outer surface of the existing pipeline.

[0023] In addition, at least one end of the first pipe section 4 or the second pipe section 5 is flush with the inner surface of the intersection well 1. The intersection well 1 is in an overall rectangular cylindrical shape. The intersection well 1 is formed by concrete pouring.
