Description

Technical Field

[0001] This utility model belongs to the field of inspection well technology, specifically, it relates to prefabricated composite material sealed and insulated inspection wells. Background Technology

[0002] Inspection wells, as core nodes in urban underground pipe networks, are widely used in municipal engineering projects such as water supply and drainage, power and telecommunications, and gas transmission, undertaking the important functions of pipe inspection, maintenance, and connection. Their performance directly affects the operational stability and service life of the pipe network system, thus occupying a key position in urban infrastructure construction.

[0003] However, most current inspection wells are constructed using brick or cast-in-place concrete structures. The construction process involves cumbersome procedures such as formwork, pouring, and curing. This not only results in a long construction period but is also susceptible to environmental factors such as weather. Furthermore, they have poor sealing performance, are prone to leakage at joints, pollute groundwater, and have poor thermal insulation, making them susceptible to frost heave damage to the well body and pipelines in cold regions.

[0004] In view of this, this utility model is hereby proposed. Utility Model Content

[0005] To address the problems of current inspection wells, which are mostly constructed of brick or cast-in-place concrete, requiring cumbersome procedures such as formwork, pouring, and curing, resulting in long construction periods, susceptibility to weather and other environmental factors, poor sealing performance, easy leakage at joints leading to groundwater pollution, poor insulation, and susceptibility to frost heave damage to the well body and pipelines in cold regions, the basic concept of the technical solution adopted in this utility model is as follows:

[0006] A prefabricated composite material sealed and insulated inspection well includes an upper well body, a lower well body, a heightening section, and a sealing cover. A connecting assembly is provided between the upper and lower well bodies. The connecting assembly includes a first flange and a second flange, which are respectively provided on the lower and upper well bodies. The first and second flanges are respectively provided with positioning grooves and positioning protrusions. The first and second flanges are sealed with structural adhesive. Several through holes are provided on both the first and second flanges. A wellhead is provided on the upper well body, and a heightening section is installed on the wellhead. A sealing assembly is installed on the top of the heightening section.

[0007] In a preferred embodiment of the present invention, the sealing assembly includes a sealing cover and a sealing ring. The sealing cover has a recessed mounting groove on its waist, and the sealing ring is installed in the mounting groove.

[0008] In a preferred embodiment of this utility model, the bottom of the heightening section is provided with a base, the top of the heightening section is provided with an interface adapted to the base, the inner diameter of the base and the outer diameter of the interface are provided with an adaptation gap for stacking and assembling multiple heightening sections, and a plurality of second reinforcing ribs are uniformly provided on the inner wall of the heightening section, the second reinforcing ribs being columnar.

[0009] In a preferred embodiment of this utility model, the sealing cover is adapted to the interface provided at the top of the heightening section, and the sealing cover is supported on the second reinforcing rib.

[0010] In a preferred embodiment of this utility model, the bottom of the lower well body is provided with three stable protrusions, and a plurality of first reinforcing ribs are evenly provided on the well body of the lower well body. The first reinforcing ribs extend along the well body and protrude outward from the well body, and their shape is wider at the top and narrower at the bottom.

[0011] In a preferred embodiment of this utility model, triangular supports are provided at the connection points of the first flange and the lower well body, the connection points of the second flange and the upper well body, the bottom and sidewall of the lower well body, and the wellhead and the area around the upper well body.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] This utility model adopts a modular design and compression molding process, connecting the upper and lower well bodies with flanges with positioning structures, structural adhesive, and bolts, which is convenient to assemble and disassemble and has strong sealing performance. The nested design of the height-increasing section can adjust the height of the well body to adapt to different engineering needs. The sealing cover and sealing ring form a double seal, combined with the integrated triangular support and outwardly protruding reinforcing ribs, which not only effectively prevents leakage and resists frost heave, but also enhances the well body's pressure resistance and deformation resistance.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0025] like Figures 1 to 7 As shown, the prefabricated composite material sealed and insulated inspection well includes an upper well body 2, a lower well body 1, a heightening section 3, and a sealing cover 4. A connecting assembly is provided between the upper well body 2 and the lower well body 1. The connecting assembly includes a first flange 101 and a second flange 201. The first flange 101 and the second flange 201 are respectively provided on the lower well body 1 and the upper well body 2. The first flange 101 and the second flange 201 are respectively provided with positioning grooves 102 and positioning protrusions 202. The first flange 101 and the second flange 201 are sealed with structural adhesive. Several through holes 5 are opened on the first flange 101 and the second flange 201. A wellhead 203 is provided on the upper well body 2. The heightening section 3 is installed on the wellhead 203. A sealing assembly is installed on the top of the heightening section 3. In this setup, the upper well body 2 and the lower well body 1 are connected by a connecting assembly. The first flange 101 and the second flange 201 are used in conjunction with the positioning groove 102 and the positioning protrusion 202 to achieve precise installation. The structural adhesive and bolts pass through the through hole 5 to ensure sealing and firmness. The wellhead 203 is used to install the height-adjusting section 3.

[0026] like Figures 1 to 7As shown, in a specific embodiment, the sealing assembly includes a sealing cover 4 and a sealing ring 402. The sealing cover 4 has a recessed mounting groove 401 on its waist, and the sealing ring 402 is installed in the mounting groove 401. In this configuration, the mounting groove 401 on the waist of the sealing cover 4 is embedded in the sealing ring 402, and the two work together to form a sealing barrier to prevent rainwater and debris from entering the well and to prevent gas from leaking out of the well.

[0027] like Figures 1 to 7 As shown, furthermore, the bottom of the heightening section 3 is provided with a base 301, and the top of the heightening section 3 is provided with an interface 302 adapted to the base 301. The inner diameter of the base 301 and the outer diameter of the interface 302 are provided with an adaptation gap for stacking and assembling multiple heightening sections 3. Several second reinforcing ribs 303 are evenly arranged on the inner wall of the heightening section 3. The second reinforcing ribs 303 are cylindrical. In this configuration, the base 301 and the interface 302 of the heightening section 3 are adapted to each other, and the height of the well body can be adjusted by stacking. The second reinforcing ribs 303 on the inner wall enhance the structural strength and improve the resistance to compression and deformation.

[0028] like Figures 1 to 7 As shown, the sealing cover 4 is further adapted to the interface 302 provided on the top of the extension section 3, and the sealing cover 4 is supported on the second reinforcing rib 303. In this configuration, the sealing cover 4 is adapted to the interface 302 of the extension section 3 and installed on the second reinforcing rib 303 to ensure that the sealing cover 4 is stable, while uniformly transmitting external pressure to ensure a long-lasting seal.

[0029] like Figures 1 to 7 As shown, furthermore, the bottom of the lower well body 1 is provided with three stabilizing protrusions 104, and a plurality of first reinforcing ribs 103 are evenly provided on the well body of the lower well body 1. The first reinforcing ribs 103 extend along the well body and protrude outward from the well body, and their shape is wider at the top and narrower at the bottom. In this configuration, the stabilizing protrusions 104 at the bottom of the lower well body 1 are used to stabilize the well body, and the first reinforcing ribs 103 on the well body disperse the lateral pressure of the soil, thereby improving the compressive strength and durability.

[0030] like Figures 1 to 7 As shown, furthermore, triangular supports 6 are provided at the connection points of the first flange 101 and the lower well body 1, the connection points of the second flange 201 and the upper well body 2, the bottom and sidewall of the lower well body 1, and around the wellhead 203 and the upper well body 2. In this configuration, the triangular supports 6 are distributed in key areas, using the stability of triangles to reinforce weak points, enhance the connection strength and overall rigidity of components, and improve the inspection well's resistance to external forces.

[0031] The implementation principle of the prefabricated composite material sealed and insulated inspection well in this embodiment is as follows: During construction, a concrete pad layer is first poured on the prepared foundation. The lower well body 1 is then placed stably, ensuring that the stable protrusion 104 at its bottom is in close contact with the pad layer. The verticality is then calibrated using a level. The triangular supports 6 of the lower well body 1, upper well body 2, and heightening section 3 are all integrally molded onto the corresponding components using a compression molding process. Subsequently, structural adhesive is evenly applied to the surface of the first flange 101. The positioning protrusion 202 on the second flange 201 of the upper well body 2 is embedded into the positioning groove 102 of the first flange 101 for initial positioning. After aligning the through holes 5 of both, bolts are inserted. When installing the bolts, an alternating tightening method is used, starting from the diagonal position of the flange and gradually expanding outwards. Each bolt is tightened repeatedly to ensure that the flange surface is evenly stressed. This completes the installation of the upper well body 2 and the lower well body 3. For connecting the manhole body 1, according to the required manhole height, insert the base 301 at the bottom of the extension section 3 into the manhole opening 203 of the upper manhole body 2 or the interface 302 at the top of the lower extension section 3. Repeat this operation to stack and assemble the extension sections 3. During the process, gently tap each layer of extension sections with a rubber hammer to adjust their position and ensure they are in place. Embed the sealing ring 402 into the recessed mounting groove 401 on the waist of the sealing cover 4, and then smoothly lower the sealing cover 4 into the interface 302 at the top of the extension section 3, ensuring that the sealing cover 4 is supported on the second reinforcing rib 303 to form a good sealing effect. This completes the installation of the entire manhole. During use, the sealing and insulation structure of this manhole can effectively resist rainwater and severe cold. The modular design allows for easy maintenance or replacement of parts by simply disassembling the corresponding extension section 3 or sealing cover 4, which simplifies the operation and reduces maintenance costs.
