Description

Technical Field

[0001] This utility model belongs to the field of engineering, and specifically relates to a prefabricated inspection well with flexible connection that has good waterproof sealing effect and is easy to operate and use. Background Technology

[0002] Inspection wells are widely used in urban underground infrastructure construction. Currently, the prefabricated inspection wells used have covers that are directly fitted onto the well body, and there are no openings on the outer wall for workers to enter for maintenance. While this type of product, where the cover and well body are directly fitted together without any maintenance openings, can meet certain usage requirements, it also has significant drawbacks. The large gap between the cover and well body results in poor sealing, allowing rainwater to easily seep in and causing poor waterproofing. Furthermore, the lack of maintenance openings requires workers to use additional tools, making operation cumbersome and inconvenient, and ultimately failing to effectively meet usage requirements.

[0003] The technical problem to be solved by this utility model is to provide a prefabricated inspection well with flexible connection, which has small interlocking gap, good sealing and waterproof effect, built-in maintenance gap, convenient and simple operation, and effectively meets the requirements of use. Utility Model Content

[0004] To address the problems of existing manhole covers and shafts, such as large gaps between the covers and shafts, poor sealing, easy rainwater seepage, poor waterproofing, lack of maintenance access requiring workers to use additional tools, cumbersome operation, and inability to effectively meet usage requirements, this utility model adopts the following technical solution:

[0005] This utility model provides a prefabricated inspection well with flexible connection, including a well body and a well cover. The edge of the well cover is connected to the side wall of the well body by a hinge. The top end face of the well body is provided with a circular raised step. The outer ring of the top end face of the well body and the circular raised step are provided with placement grooves. Waterproof sealing rings are provided in the placement grooves. The outer ring of the front end of the well cover is provided with a circular wrapping wall. The shape and size of the circular wrapping wall are completely matched with the circular raised step. The well cover is fastened to the well body by the cooperation of the circular wrapping wall and the circular raised step.

[0006] Preferably, the upper part of the outer wall of the well body and the side wall of the well cover are provided with concave semi-circular notches that facilitate maintenance and are located in the same vertical direction.

[0007] Preferably, the lower part of the outer side of the well body is provided with a pipe inlet, and the upper end face of the well cover is provided with a movable inlet hole.

[0008] The beneficial effects of this utility model are as follows: the gap between the wall and the convex edge is small, the addition of two sealing rings provides good sealing and waterproofing, and both the well body and the well cover have built-in maintenance gaps, making operation convenient and simple, and effectively meeting the usage requirements. Attached Figure Description

[0009] Figure 1 This is a schematic diagram of the structure of one embodiment of the present invention.

[0010] Figure 2 This is a diagram showing the manhole cover in the closed position. Detailed Implementation

[0011] The preferred embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0012] Please see Figure 1 A prefabricated inspection well with flexible connection includes a well body 1 and a well cover 2. The edge of the well cover 2 is hinged to the side wall of the well body 1. The top end face of the well body 1 has a circular raised edge step 11. The outer ring of the top end face of the well body 1 and the circular raised edge step 11 both have placement grooves 12. Each placement groove 12 contains a waterproof sealing ring 13. Adding two sealing rings greatly improves the sealing performance. The outer ring of the front end of the well cover 2 has a circular retaining wall 21. The circular retaining wall 21 perfectly matches the shape and size of the circular raised edge step 11. The well cover 2 is fastened to the well body by the cooperation of the circular retaining wall 21 and the circular raised edge step 11. Figure 2 As shown, after the two parts are fastened together, the gap between the well body and the well cover is very small, resulting in better sealing and waterproofing.

[0013] The upper part of the outer wall of the well body 1 and the side wall of the well cover 2 are provided with concave semi-circular notches 3 for easy maintenance and are located in the same vertical direction. This makes it more convenient for workers to go down for maintenance without the need for additional tools. When multiple inspection wells are used in combination, the placement can be ensured by observing the notches.

[0014] The well body 1 has a pipe inlet 14 on the lower part of the outer side, and the well cover 2 has a movable inlet 22 on the upper end face, making operation and use more convenient.

[0015] The beneficial effects of this utility model are as follows: the gap between the wall and the convex edge is small, the addition of two sealing rings provides good sealing and waterproofing, and both the well body and the well cover have built-in maintenance gaps, making operation convenient and simple, and effectively meeting the usage requirements.

[0016] The above embodiments and figures are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
