Screw-fixed manhole cover lock-the guardian of urban safety
I. Preface
In our daily life, manhole cover is a kind of infrastructure that we can often see. However, with the acceleration of urban construction and the complexity of underground pipelines, the safety problem of manhole cover has become increasingly prominent. In recent years, manhole covers have been stolen in many places, which not only affects the beauty of the city, but also poses a serious safety hazard to pedestrians. In view of this situation, many cities have begun to adopt new screw-fixed manhole cover locks to ensure public safety.
Second, the product introduction
1. Structural features: Screw-fixed manhole cover locks are usually made of stainless steel, which has strong corrosion resistance and pressure resistance. This type of manhole cover lock firmly connects the manhole cover and the well frame through special screws, and can only be opened or disassembled by using corresponding tools, which greatly improves the safety performance of the manhole cover.
2. Convenient installation: Compared with the traditional
For the manhole cover lock, the screw-fixed installation is simpler and more convenient, and the installation operation can be completed only by placing the manhole cover in the designated position and fastening it with screws, and it can also be quickly disassembled when it needs to be replaced or repaired, which provides convenient conditions for later maintenance.
3. Wide scope of application: This design can be widely used in various materials (such as cast iron, composite materials, etc.) and manhole covers with different shapes and sizes, which can effectively avoid quality problems caused by improper construction while ensuring its anti-theft function.
4. Environmental protection and energy saving: because it is made of high-strength materials, it has a longer service life; In addition, it can be adjusted and reformed according to the actual situation, which not only saves resources but also conforms to the concept of sustainable development.
Third, the application case
In order to improve the safety level of pavement facilities, the municipal administration department of a city decided to upgrade all manhole covers in the area, including introducing the above-mentioned "screw-fixed" technical scheme to replace the original equipment. After a period of actual test operation, it is found that:
(1) From the effect, the theft rate and damage degree are obviously reduced;
(2) From the perspective of economic benefits, although the initial input cost is high, the overall cost has decreased due to long-term stability and reliability;
(3) At the same time, it is also conducive to enhancing the public's satisfaction and support for government work, which has a positive impact.
IV. Conclusion
In a word, the appearance of "screw-fixed manhole cover lock" is undoubtedly one of the difficult problems that have plagued city managers for a long time. "A small screw" bears a great responsibility for the safety of people's lives and property! I believe that more outstanding scientific and technological achievements like this will be promoted and applied to actual production and life in the future, and jointly build a beautiful and harmonious social environment!
