When not needed, the parts can be detached one by one, and then the parts can be assembled and molded in different places for reuse, and can be recycled for multiple times. And once the traditional masonry well and the cast-in-place well are removed, the traditional masonry well and the cast-in-place well become a pile of construction waste.

5. The durability is good: the service life of the fabricated precast concrete inspection well can be as long as that of the single building engineering, and is longer than that of the fabricated precast concrete inspection well. The service life is more than 70 years and 2 times higher than that of the traditional masonry well.

6. Can adjust the height wantonly, the flexibility is good, the precision is high: the assembled precast concrete inspection well is a standardized universal component, the shaft adjusting ring 2 has specifications of different heights of 600 mm, 500 mm, 300 mm, 250 mm and 200mm, can be assembled into drainage wells or inspection wells with different depths according to actual needs on site, and has good adjustability and flexibility. The adjusting precision can reach 10mm level.
