Description

Technical Field

[0001] This utility model belongs to the field of prefabricated well technology, specifically relating to prefabricated wells that are easy to clean and maintain. Background Technology

[0002] In municipal engineering construction, precast wells are widely used as key facilities in drainage and sewage systems. Traditional sewage wells are generally constructed on-site using reinforced concrete, resulting in long construction periods and high costs. Precast wells can effectively solve these problems, but existing precast wells still have certain issues:

[0003] On the one hand, the internal filtration structure of traditional precast wells is not designed reasonably. When water is introduced into the well through the inlet pipe, impurities in the water tend to accumulate inside the well, and existing filtration devices are difficult to clean. For example, most common filtration equipment is fixedly installed, making it difficult to remove for a comprehensive and thorough cleaning. This requires a lot of manpower and time, and the cleaning effect is not good, which makes the water quality inside the well easily polluted and affects the normal functions of drainage and sewage discharge.

[0004] On the other hand, the connection method of traditional precast wells has defects. The connection between the sections is not stable enough. During long-term use, it is prone to loosening and misalignment due to factors such as changes in groundwater level and soil settlement. This not only affects the sealing of the well body, but also leads to a decrease in the stability of the well structure, increasing maintenance costs and safety hazards.

[0005] Furthermore, traditional precast wells also face many inconveniences during installation and dismantling. Due to the lack of a reasonable positioning and guiding structure, it is difficult to ensure accurate alignment of each section during installation, which increases the difficulty of construction and time costs; while when maintenance or replacement of parts is required, the dismantling process is very cumbersome, which is not conducive to quick and efficient maintenance work.
