Description

Technical Field

[0001] This utility model relates to the field of valve wells and drainage inspection wells in municipal engineering and high-standard farmland construction, specifically to well bases. Background Technology

[0002] In existing municipal engineering and high-standard farmland construction, water pipes, gas pipes, cables, and other pipelines are typically laid underground. To facilitate installation and maintenance, valves are installed at regular intervals along these pipelines. Valve wells are also installed to protect these valves and to meet the needs of valve opening, closing, and maintenance. Simultaneously, drainage inspection wells are typically installed at pipe junctions, bends, changes in pipe diameter or slope, and at regular intervals along straight pipelines to facilitate the inspection of ancillary structures, thus greatly facilitating the installation and maintenance of urban sewage discharge and high-standard farmland irrigation systems.

[0003] In areas where concrete transportation is inconvenient, existing valve wells or drainage inspection wells primarily use ordinary sand and gravel as a foundation before placing the well base. During pipe installation, external supports or bricks are needed. However, these supports or bricks are installed on the foundation, which is highly susceptible to settlement or displacement due to well construction or ground movement, affecting pipe installation and construction progress. While split-type valve wells, such as the prefabricated valve well described in application number 202211529459.1, include a well chamber, sealing components, a well shaft, a foundation structure, and a well cover, with two sealing components located at two installation ports to seal the connection between the installation port and the pipe, achieving a waterproof seal, this design changes the traditional brickwork or cast-in-place concrete construction process. However, during well construction, additional supports or bricks are still needed to support the pipes inside the well, making settlement or displacement due to well construction or ground movement a possibility. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a well base. This well base has a receiving platform that is coplanar with the base plate. The support on the receiving platform supports and limits the pipeline, preventing tilting or displacement due to well construction, effectively ensuring pipeline installation efficiency and construction progress, and stable operation.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] The well base includes an inner ring base plate, a circular inner ring disposed at the edge of the inner ring base plate, and an arc-shaped outer ring disposed opposite to the circular inner ring. A receiving gap is formed between the circular inner ring and the arc-shaped outer ring to accommodate the well body. The bottom of the arc-shaped outer ring is provided with an outer ring base plate connected to the inner ring base plate. At least one set of receiving platforms extending outward from the arc-shaped outer ring is provided on the outer ring base plate.

[0007] Preferably, the receiving platform is positioned opposite any pipe opening and is coplanar with the outer ring base plate and the inner ring base plate, and is used to place supports that provide support for the pipeline.

[0008] Preferably, the outer edge of the receiving platform is provided with a baffle to limit the position of the support and prevent the support from collapsing or shifting.

[0009] Preferably, the baffle is arranged around the outer edge of the receiving platform and connected to two adjacent sets of arc-shaped outer rings.

[0010] Preferably, the baffle has a first chamfer at the bend and a second chamfer at the connection between the baffle and the arc-shaped outer ring.

[0011] Preferably, the receiving platform is provided with three or four sets.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] The well base of this utility model is suitable for valve wells, drainage inspection wells, etc. It is equipped with a receiving platform that is coplanar with the base plate. The support on the receiving platform supports and limits the pipeline, preventing tilting or displacement due to well construction, effectively ensuring pipeline installation efficiency and construction progress, and stable operation.
