Description

Technical Field

[0001] The utility model relates to an inspection well which is convenient for connecting rainwater and sewage pipes. Background Art

[0002] In municipal engineering, the distribution of sewer systems is huge, and sewers are basically spread across various regions. Although sewers are located underground, they also need to be maintained regularly, such as for cables, sewage channels, etc. If damaged, personnel need to go down for repair, and regular inspections and maintenance may also be required usually. Therefore, an inspection well needs to be set at a designated place to facilitate personnel to enter underground. At the same time, both sides of the inspection well are connected to cement pipes. After maintenance personnel enter the inspection well, they can enter through the connection ports on both sides to observe the conditions inside the cement pipes at both ends. In the existing inspection well and cement pipe connection, an opening is made on both sides of the inspection well, and one end of the cement pipe is inserted into the opening on both sides of the inspection well at the installation site. Then, the connection between the two is sealed with cement pouring, so that the connection port can be sealed and leakage will not occur, and the connection can be stable. However, this connection method requires on-site cement pouring operations, which is very inconvenient. Content of the Utility Model

[0004] The above technical problems of the utility model are mainly solved by the following technical solutions:

[0005] An inspection well which is convenient for connecting rainwater and sewage pipes of the utility model is mainly formed by steel bars and cement pouring; it includes a cement layer and a steel bar main body wrapped in the cement layer; the steel bar main body is welded by solid iron pipes, which can be circular or square, and the structure of the steel bar main body determines the overall shape of the inspection well; circular holes are respectively opened on the upper end surface and both side surfaces of the steel bar main body; step a and step b extending outwards are respectively arranged at the circular holes on both sides of the steel bar main body.

[0006] Preferably, step a is close to the side wall of the inspection well, and step b continues to extend outwards from the end of step a.

[0007] Preferably, the diameter of step a is larger than the diameter of step b.

The sealing rings can be sleeved according to the gap between the cement pipe and the steps, so that an interference fit is formed between the steps and the cement pipe, and thus the connection can be sealed and water leakage will not occur. The steps are formed by first welding a structure on the steel bars and then pouring cement, so that the load-bearing capacity and strength of the steps can be ensured, ensuring that the connection is stable after the cement pipes are connected. Compared with the existing method of sealing the connection with cement on site, the installation is simple and convenient for on-site operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The following will elaborate on the preferred embodiments of the present invention in conjunction with the drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0018] As Figures 1-3As shown in the figure, an inspection well facilitating the connection of rainwater and sewage pipes, mainly used for inspection wells in municipal engineering such as sewers, is a well that connects sewer pipes and allows maintenance personnel to enter. It is mainly made of steel bars and cement; it includes a cement layer 6 and a steel bar main body 1 wrapped inside the cement layer 6; the steel bar main body 1 is welded by solid iron pipes, which can be circular or square, and the structure of the steel bar main body 1 determines the overall shape of the inspection well; circular holes are respectively opened on the upper end face and both side faces of the steel bar main body 1. Except for the above 3 circular holes, the rest of the steel bar main body 1 is a network formed by the cross of iron pipes, which can ensure strength and make the inspection well stable; outward-extending steps a7 and steps b8 are respectively arranged at the two circular holes on both sides of the steel bar main body 1.

[0019] The step a7 is close to the side wall of the inspection well, and the step b8 continues to extend outward from the end of the step a7. Specifically, for the structure on the steel bar main body 1, after pouring cement, the shape presented on the cement layer 6 will be the same as the internal steel bar structure; there are steps a7 and steps b8 on the steel bar main body 1, so after pouring, there will also be cement steps.

[0020] The diameter of the step a7 is larger than that of the step b8; specifically, after the step a7 protrudes, the diameter is further reduced on the end face of the step a7 to form the step b8. Both sides of the inspection well are connected to sewer pipes. Currently, most sewer pipes are cement pipes. The existing connection method between the cement pipe and the inspection well is to insert the end of the cement pipe into the two circular holes reserved on both sides of the inspection well, and then perform cement sealing operation on the connection between the cement pipe and the inspection well on site, which can ensure that there is no leakage at the connection and ensure the stability of the connection; the design of the steps a7 and steps b8 in this application allows the cement pipe to be sleeved on the step b8, and there are steel bars inside, so the bearing capacity of the steps a7 and steps b8 can be ensured, and this kind of sleeving is simpler and more convenient during on-site installation.

[0021] A sealing ring is coated on the outer ring of the step b8; specifically, when the cement pipe is sleeved on the step b8, the sealing ring can be coated according to the gap between the cement pipe and the step b8, which can form an interference fit between the step b8 and the cement pipe, eliminating the need for on-site cement sealing at the connection, not only ensuring the sealing performance of the connection but also facilitating current installation and simplifying the installation process.

[0022] An inspection well opening 4 is arranged at the middle position of the upper end of the steel bar main body 1, and a plurality of handles 5 are symmetrically arranged on both side edges; further, the handles 5 on the steel bar main body 1 protrude upward. After pouring the cement layer 6, the handles 5 still protrude above the cement layer 6 for lifting the inspection well during transportation and installation; and the inspection well opening 4 is not covered by the cement layer 6 either.

[0023] The beneficial effects of the present utility model are:

[0024] On the basis of the original inspection well, two protruding steps are made at the places where the cement pipes are connected on both sides of the inspection well, and sealing rings are coated on the steps. The sealing rings can be sleeved according to the gap between the cement pipes and the steps, so that an interference fit is formed between the steps and the cement pipes, and thus the connection can be sealed and water leakage will not occur. The steps are formed by first welding a structure on the steel bars and then pouring cement. In this way, the load-bearing capacity and strength of the steps can be ensured, ensuring the stability of the connection after the cement pipes are connected. Compared with the existing method of sealing the connection with cement on site, the installation is simple and convenient for on-site operation.
