Abstract
Description
Technical Field
[0001] This utility model is a reinforced concrete inspection well, belonging to the field of construction. Background Technology
[0002] Municipal drainage pipes are generally laid under municipal roads, with inspection wells installed at regular intervals as needed. This allows for inspection and repair of the pipeline system in case of malfunctions. Inspection wells are primarily made of materials such as brick, reinforced concrete, and plastic. Currently, sewage and stormwater inspection wells on municipal roads mainly use reinforced concrete structures. For large-diameter pipes, reinforced concrete structures are also used due to heavy vehicle loads and soil pressure.
[0003] Currently, in engineering applications, the connection method between reinforced concrete pipes and inspection wells is as follows: both the inlet and outlet pipes are inserted into the inspection well wall by insertion, and the connection is sealed with concrete or brickwork with cement mortar to prevent leakage. However, due to unreasonable design or improper construction, the connection between the well body and the base is prone to displacement and seepage, seriously affecting the service effectiveness and lifespan of the inspection well. Utility Model Content
[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a reinforced concrete inspection well to solve the problem.
[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a reinforced concrete inspection well, comprising a well body formed by concrete casting, a water inlet connection section, and a water outlet connection section; wherein the well body, the water inlet connection section, and the water outlet connection section are integrally formed; the well body is installed on a base; the base is formed by concrete casting; the base has a hexagonal mounting groove; the well body is installed on the mounting groove, and concrete is poured to fix the well body in the mounting groove.
[0006] Preferably, the mounting groove has a plurality of arc-shaped openings, which are connected to the bottom surface of the mounting groove.
[0007] Preferably, the arc-shaped opening is located at the midpoint of the side length of the hexagonal mounting groove.
[0008] Preferably, the bottom surface of the mounting groove is patterned.
[0009] Preferably, the pattern consists of several regularly distributed raised stripes.
[0010] Preferably, the inner radius of the mounting groove is larger than that of the well body.
[0011] Preferably, the inner diameter circle radius is at most 3 cm greater than the wellbore radius.
[0012] Beneficial effects
[0013] The well body, inlet connection section, and outlet connection section of this utility model are designed as a single piece, which greatly enhances the overall structural strength of the inspection well and effectively prevents well body displacement or tilting caused by loose connections between components, thus improving the stability and safety of the inspection well during use. The hexagonal mounting groove on the base and the raised strip pattern design on the bottom of the groove not only increase the friction between the well body and the base to prevent the well body from sliding, but also effectively eliminate air bubbles during concrete pouring, ensuring a tight fit and good seal between the mounting groove and the well body, effectively preventing water seepage.

[0014] Other features, objects, and advantages of this invention will become more apparent from the following detailed description of non-limiting embodiments with reference to the accompanying drawings:

[0016] Figure 2 This is a side view of a reinforced concrete inspection well according to the present invention.
[0017] Figure 3 This is a schematic diagram of the structure of the base and the well body of this utility model.
[0018] Figure 4 This is a structural schematic diagram of the base of this utility model. Detailed Implementation
[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0020] Please see Figures 1-4 This utility model provides a technical solution for a reinforced concrete inspection well, which includes a well body 1 integrally cast from concrete, a water inlet connection section 2, and a water outlet connection section 3.
[0021] The well body 1, the water inlet connection section 2, and the water outlet connection section 3 are designed as an integral molded structure to ensure overall stability and sealing.
[0022] Furthermore, the well body 1 is mounted on the base 4, which is also formed by concrete casting.
[0023] Furthermore, the base 4 is provided with a hexagonal mounting groove 41 for securely placing the well body 1. The hexagonal design facilitates the placement of the well body 1 and allows the well body 1 to rotate within the mounting groove, thereby adjusting the rotation direction of the inlet connection section 2 and the outlet connection section 3.
[0024] Furthermore, the upper edge of the mounting groove 41 is provided with several arc-shaped openings 42, which are connected to the bottom surface of the mounting groove 41. Thus, when concrete is poured, the injection port of the concrete preferably corresponds to the arc-shaped opening 42, and the concrete flowing in through the arc-shaped opening 42 can better fill the gap between the mounting groove 41 and the well body 1, making both more stable and sealed.
[0025] Preferably, the arc opening 42 is located at the middle of the side length of the hexagonal mounting groove 41. In this way, relying on the shape of the hexagon, even if the well body 1 is damaged, the arc opening 42 can still allow concrete to flow into the gap between the mounting groove 41 and the well body 1.
[0026] The bottom surface of the mounting groove 41 is designed with a pattern 43, specifically a number of regularly distributed raised strip-shaped structures. The pattern 43 serves two purposes: firstly, it prevents the well body 1 from slipping on the mounting groove 41; secondly, during pouring, after air bubbles are expelled, the mounting groove 41 and the well body 1 achieve a good sealing effect. In one embodiment, the pattern 43 consists of a number of regularly distributed raised strips. Thus, when the concrete is poured, it covers the raised strips, ensuring a seal between the mounting groove 41 and the well body 1.
[0027] Furthermore, the inner diameter radius of the mounting groove 41 is designed to be slightly larger than the radius of the well body 1, specifically at most 3cm larger than the radius of the well body 1.
[0028] This size design ensures that the manhole body 1 can be smoothly placed into the installation slot 41, and also ensures a tight fit between the manhole body 1 and the base 4, facilitating subsequent concrete pouring and fixing. Furthermore, the manhole body 1 can be fine-tuned during pipe installation, making joint installation easier. During installation, the manhole body 1 is first placed into the hexagonal installation slot 41 of the base 4.
[0029] Subsequently, the placement and angle of the well body 1 are adjusted; concrete is poured into the gap between the well body 1 and the mounting groove 41 to firmly fix the well body 1 in the mounting groove 41. The concrete is then defoamed and smoothed. After the concrete has cured, the well body 1 and the base 4 form a stable whole, ensuring the stability and safety of the inspection well during use.
[0030] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics.
