Description

Technical Field

[0001] This utility model relates to an installation structure for rainwater and sewage well covers, belonging to the field of municipal engineering technology. Background Technology

[0002] With urbanization and increased sewage collection rates, municipal pipelines, serving as the arteries for drainage and sewage disposal in residential environments, are ubiquitous in daily life. Inspection wells, as key components for the maintenance and cleaning of municipal pipelines, are their primary markers. Currently, manhole covers are typically connected to the well shaft using an overlapping method, which makes the area around the cover prone to collapse, affecting the overall smoothness of the road and increasing discomfort for drivers. Furthermore, manhole covers are mostly placed directly on the cover base, resulting in low installation stability. Under the pressure of passing vehicles, they easily shake, generating noise and disturbing the rest of nearby residents. Loose manhole covers also increase the risk of pedestrians falling into the well.

[0003] Chinese patent document CN218405555U discloses a reinforcement structure for a manhole casing, including a manhole casing, a cover plate, and a cover seat. The cover plate is disposed on the manhole casing, and the cover seat is disposed at the end of the cover plate near the ground. It also includes multiple sets of snap-fit ​​blocks rotatably mounted on the cover plate. Multiple sets of snap-fit ​​grooves are formed on the outer peripheral wall of the manhole casing. The rotation axes of the multiple sets of snap-fit ​​blocks are all parallel to the axis of the manhole casing. The snap-fit ​​blocks are engaged and adapted to the snap-fit ​​grooves. A fixing component is provided on the cover plate for fixing the position of the snap-fit ​​blocks. This structure achieves the effect of fixing the snap-fit ​​blocks by engaging and fixing them to the snap-fit ​​grooves, and then fixing the snap-fit ​​blocks by the fixing component, making the connection between the cover plate and the manhole casing more stable. The cover plate bears the load of the road surface, thus completing the reinforcement effect of the manhole casing.

[0004] However, the reinforcement structure of this inspection well has the disadvantages of complex structure and high manufacturing cost. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a rainwater and sewage well cover installation structure.

[0006] This utility model is achieved through the following technical solution:

[0007] A storm and sewage manhole cover installation structure includes a manhole cylinder, a manhole cover seat, and a manhole cover. The manhole cylinder includes a concrete manhole cylinder and a steel manhole cylinder. The steel manhole cylinder is pre-embedded at one end of the concrete manhole cylinder. The manhole cover seat is threadedly connected to the steel manhole cylinder. The manhole cover is placed inside the manhole cover seat and connected to the manhole cover seat through several locking components.

[0008] One end face of the steel well casing is located inside the concrete well casing, and the other end face is coplanar with the end face of the concrete well casing.

[0009] The steel well casing has an annular groove coaxially formed on it, and the outer wall of the annular groove is threaded.

[0010] The manhole cover seat includes a hollow bolt and an annular plate, with the annular plate coaxially disposed at one end of the hollow bolt.

[0011] The outer diameter of the annular plate is the same as the outer diameter of the concrete well shaft.

[0012] The annular plate is provided with a number of through holes B, which are arranged along the axial direction of the annular plate. The number of through holes B is the same as the number of locking components on the manhole cover. The inner wall of the annular plate is provided with through holes A in the radial direction at the position corresponding to the through holes B, and one end of the through hole A is connected to the through hole B.

[0013] The manhole cover is equipped with four locking components that connect to the manhole cover base.

[0014] The locking assembly includes a compression spring and a top post. A sliding hole is provided radially inside the manhole cover, and the sliding hole is a blind hole. The top post is slidably connected to the sliding hole. One end of the compression spring is connected to the bottom of the sliding hole, and the other end is connected to one end of the top post, pushing the top post part out of the sliding hole.

[0015] The beneficial effects of this utility model are as follows: a steel well cylinder is pre-embedded at one end of the concrete well cylinder to improve the load-bearing capacity of the concrete well cylinder. The well cover seat is threadedly connected to the steel well cylinder, ensuring a reliable connection and preventing collapse around the well cover seat. After the well cover is placed in the well cover seat, it is connected to the well cover seat through a locking component to ensure that the well cover is firmly installed, preventing the well cover from shaking and generating noise under the pressure of passing vehicles. At the same time, it reduces the risk of pedestrians falling into the well due to the loose well cover. The entire inspection well includes a well cylinder, a well cover seat, a well cover, and a locking component, with a simple structure and low manufacturing cost. Attached Figure Description

[0021] The technical solution of this utility model is further described below, but the scope of protection is not limited to what is described.

[0022] like Figures 1 to 4 As shown, the present invention discloses a stormwater and sewage manhole cover installation structure, comprising a manhole cylinder 1, a manhole cover seat, and a manhole cover 9. The manhole cylinder 1 includes a concrete manhole cylinder 4 and a steel manhole cylinder 3. The steel manhole cylinder 3 is pre-embedded at one end of the concrete manhole cylinder 4. The manhole cover seat is threadedly connected to the steel manhole cylinder 3. The manhole cover 9 is placed inside the manhole cover seat and connected to the manhole cover seat through multiple locking components. In use, the steel manhole cylinder 3 is pre-embedded at one end of the concrete manhole cylinder 4 to improve the load-bearing capacity of the concrete manhole cylinder 4. The manhole cover seat is threadedly connected to the steel manhole cylinder 3, ensuring a reliable connection and preventing collapse around the manhole cover seat. After the manhole cover 9 is placed inside the manhole cover seat, it is connected to the manhole cover seat through locking components, ensuring that the manhole cover 9 is firmly installed and preventing the manhole cover 9 from shaking and generating noise under the pressure of passing vehicles. It also reduces the risk of pedestrians falling into the manhole due to the manhole cover 9 becoming loose. The entire inspection manhole includes the manhole cylinder 1, the manhole cover seat, the manhole cover 9, and the locking components, with a simple structure and low manufacturing cost.

[0023] One end face of the steel well shaft 3 is located inside the concrete well shaft 4, and the other end face is coplanar with the end face of the concrete well shaft 4.

[0024] The steel well casing 3 has a coaxially formed annular groove 2, and the outer wall of the annular groove 2 is threaded. The thread on the annular groove 2 is used for threaded connection with the hollow bolt 6.

[0025] The manhole cover seat includes a hollow bolt 6 and an annular plate 7, with the annular plate 7 coaxially disposed at one end of the hollow bolt 6.

[0026] The outer diameter of the annular plate 7 is the same as the outer diameter of the concrete well shaft 4.

[0027] The annular plate 7 is provided with four through holes B8 evenly distributed along the axial direction of the annular plate 7, and the number of through holes B8 is the same as the number of locking components on the manhole cover 9. The inner wall of the annular plate 7 is provided with through holes A5 radially at the position corresponding to the through holes B8, and one end of the through hole A5 is connected to the through hole B8.

[0028] The manhole cover 9 is provided with four locking components that are connected to the manhole cover seat.

[0029] The locking assembly includes a compression spring 11 and a top post 12. A sliding hole 10 is provided radially inside the manhole cover 9, and the sliding hole 10 is a blind hole. The top post 12 is slidably connected to the sliding hole 10. One end of the compression spring 11 is connected to the bottom of the sliding hole 10, and the other end is connected to one end of the top post 12, pushing part of the top post 12 out of the sliding hole 10.

[0030] The working principle or usage process of the storm and sewage well cover installation structure of this utility model is as follows:

[0031] The hollow bolts 6 in the manhole cover seat are threaded to the steel manhole barrel 3 and tightened to ensure a reliable connection between the manhole cover seat and the manhole barrel 1. Then, the manhole cover 9 is placed inside the annular plate 7, which positions the manhole cover 9. The hollow bolts 6 support the manhole cover 9. Due to the compression of the inner wall of the annular plate 7, the pusher 12 retracts completely into the sliding hole 10, and the compression spring 11 is further compressed. The manhole cover 9 is rotated. When the locking components on the manhole cover 9 are aligned with the through holes A5 on the annular plate 7, the compression spring 11 returns to its original deformation and elongates. One end of the pusher 12 passes through the through hole A5 and extends into the through hole B8, thereby firmly locking the manhole cover 9 onto the manhole cover seat. This prevents the manhole cover 9 from shaking and generating noise under the pressure of passing vehicles, and significantly reduces the risk of pedestrians falling into the manhole due to the loosening of the manhole cover 9. When it is necessary to remove the manhole cover 9, first use a tool to push the top post 12 back into the sliding hole 10, then rotate the manhole cover 9 and remove it from the annular plate 7.
