Description

Technical Field

[0001] This utility model relates to underground pipeline construction, specifically to an installation structure for an underground pipeline flow meter. Background Art

[0002] An underground pipeline flow meter well refers to a well in which a flow meter is installed and sealed with a manhole cover to monitor the flow rate in underground pipelines. Its main function is to monitor changes in flow rate in real time through the flow meter installed in the underground pipeline, accurately measure the flow rate, and feed the data back to the monitoring system. This allows for the timely detection of anomalies in the operation of underground pipelines, enabling prompt action and ensuring the safe operation of the underground pipelines.

[0003] The conventional construction method for underground pipeline flow meter wells is generally a brick or concrete structure, typically consisting of a well cover, well walls, well bottom, and flow meters. Insertion flow meters and ultrasonic flow meters are installed in the upper part of the pipeline and connected to the monitoring system via sensor signal cables. The well cover, made of precast reinforced concrete, is used to seal the flow meter well. Construction of the flow meter well involves first excavating the well bottom, implementing safety measures, and ensuring the foundation is properly treated before pouring the well bottom bedding layer and installing the reinforcing steel for the well bottom and walls (for brick wells, construction begins directly on the well walls). Pre-installed sleeves are also installed, and finally, the concrete for the well bottom and walls is poured.

[0004] Based on the existing construction methods, the flow meter well construction structure is relatively complex and the connections between structures are tight, resulting in a long construction period, high construction costs, and easy water seepage at joints, bottom of the well, well wall, and reserved casing. Summary of the Invention

[0005] The purpose of this invention is to provide an installation structure for an underground pipeline flow meter to solve the above-mentioned problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an installation structure for an underground pipeline flow meter, comprising a pre-embedded pipeline and a well component welded and assembled together, wherein the two are in a perpendicular relationship;

[0007] A flow meter is fixedly installed on the pre-embedded pipeline and arranged inside the well section.

[0008] The wellbore component includes a well wall, on which a plurality of wiring pipes arranged in a linear array near the port section are provided.

[0009] Preferably, the bottom of the well section is an arc-shaped part, and well bottom plates are welded to both ends of the arc-shaped part. The arc-shaped part fits against the upper and lower outer walls of the pre-embedded pipe, and the well bottom plates also contact the outer walls of the pre-embedded pipe.

[0010] Preferably, the well bottom plate, the pre-embedded pipe and the arc-shaped part are provided with welded seams arranged inside and outside.

[0011] Preferably, the radius of the arc-shaped portion is smaller than the radius of the pre-embedded pipe.

[0012] Preferably, the portion of the well bottom plate between the arc-shaped portion and the well wall is the well bottom;

[0013] The pre-embedded pipe has an inlet that connects to the inside of the well. The inlet is flush with the bottom of the well, and the flow meter's detection end is located at the inlet.

[0014] Preferably, the flow meter is arranged close to the well wall.

[0015] Preferably, the well cover plate is also included for sealing the cross-section of the well section, and the outer side of the well cover plate is symmetrically and rotatably provided with lifting rings.

[0016] In the above technical solution, the installation structure for an underground pipeline flow meter provided by this utility model has the following beneficial effects: it replaces the traditional brick or concrete-cast flow meter well with a steel flow meter well welded integrally with the underground pipeline. During the fabrication of the steel flow meter well, a suitable steel pipe can be used as the well wall according to the size of the flow meter well, a steel plate and underground pipeline components form the well bottom, and the well cover is made of prefabricated steel plate. The thickness of the steel plate must ensure that the flow meter well has sufficient structural strength and stability to withstand road vehicle loads and other external stresses. The connection between the flow meter well bottom and the underground pipeline, as well as the connection between the reserved wiring pipe and the well wall, is achieved by welding, avoiding the leakage risk caused by inadequate sealing of the reserved sleeves in traditional concrete or brick-built flow meter wells.

[0017] Secondly, the materials used in this structure are readily available. The steel pipes and plates used can generally be reused on-site, making them much cheaper than reinforced concrete or brickwork. Furthermore, the fabrication and installation time is short, unlike poured concrete flow meter wells which require slow curing, thus shortening the construction period and saving a significant amount of money. At the same time, the steel flow meter well has better integrity and tightness, reducing the risk of groundwater leakage and minimizing the need for rework later. Attached Figure Description

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] like Figure 1-4 As shown, an installation structure for an underground pipeline flow meter includes a pre-embedded pipeline 1 and a shaft component. A flow meter 4 is installed on the outer wall of the pre-embedded pipeline 1 via a flange, and the detection end of the flow meter 4 extends into the interior of the pre-embedded pipeline 1. Two water inlets are symmetrically opened on the outer wall of the pre-embedded pipeline 1, and the detection end of the flow meter 4 is located in one of the water inlets.

[0027] The bottom of the well section is an arc-shaped part, and well bottom plates 8 are welded to both ends of the arc-shaped part to form the well bottom 5-1. Then the arc-shaped part is attached to the outer wall of the pre-embedded pipe 1. At this time, the arc-shaped part perfectly fits the outer wall of the pre-embedded pipe 1, and the well bottom plate 8 is also in contact with the outer wall of the pre-embedded pipe 1.

[0028] The bottom plate 8, the pre-embedded pipe 1, and the arc-shaped part are welded together by electric arc welding, so that weld seams 2 are formed on the inside and outside of the well passage component.

[0029] Furthermore, the wellbore component includes a well wall 5-2, on which multiple wiring pipes 7 arranged in a linear array near the port section are provided.

[0030] In addition, the embodiment also includes a manhole cover plate 6 for sealing the port section of the manhole component, and a lifting ring 6-1 is symmetrically and rotatably provided on the outer side of the manhole cover plate 6.

[0031] In the aforementioned technology, traditional brick or concrete flow meter wells are replaced with steel flow meter wells welded integrally with underground pipelines. During the fabrication of the steel flow meter well, appropriate steel pipes are used for the well walls, steel plates and underground pipeline components form the well bottom, and the well cover is made of prefabricated steel plates. The thickness of these steel plates must ensure that the flow meter well has sufficient structural strength and stability to withstand road vehicle loads and other external stresses. The connection between the flow meter well bottom and the underground pipeline, as well as the connection between the pre-installed wiring conduit and the well wall, is achieved through welding, avoiding the leakage risk caused by inadequate sealing of pre-installed sleeves in traditional concrete or brick flow meter wells.

[0032] Secondly, the materials used in this structure are readily available. The steel pipes and plates used can generally be reused on-site, making them much cheaper than reinforced concrete or brickwork. Furthermore, the fabrication and installation time is short, unlike poured concrete flow meter wells which require slow curing, thus shortening the construction period and saving a significant amount of money. At the same time, the steel flow meter well has better integrity and tightness, reducing the risk of groundwater leakage and minimizing the need for rework later.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
