Manhole: Facilitating Maintenance and Inspection of Pipelines

Description：

    Inspection wells are plastic injection moulded or brick well-like structures, installed in the 

drainage pipe intersection, turning points, pipe diameter or slope changes, waterfalls, etc., in

order to facilitate regular inspection, cleaning and unblocking or down the well to operate the

inspection. 

Features:

1、Space-Saving Design

2、Cost-Effective Lifespan

3、Leak-Proof Sealing

4、Durable & Recyclable

5、Eco-Friendly Materials

6、Efficient Drainage System

Advantages:

1、Made from high-molecular resin materials,Plastic inspection wells with smaller 

diameters,significantly reduce the land space occupied by buried inspection chambers 

compared to traditional one.

2、Quick and easy installation, small construction area, convenient maintenance, low 

maintenance costs, and long service life lead to lower overall cost.

3、Excellent sealing performance prevents sewage leakage, thereby saving sewage treatment costs.

4、Plastic inspection chambers are corrosion-resistant, aging-resistant, long-lasting, and 

recyclable, significantly reducing material costs.

5、The materials are non-toxic, odorless, and recyclable, meeting environmental protection 

requirements.Excellent sealing performance prevents groundwater pollution, making them 

environmentally friendly construction materials.

6、Efficient drainage. The inner wall is smooth and fluent, equipped with infusion groove, dirt 

is not easy to be retained, which reduces the possibility of clogging, has excellent drainage 

performance, and the discharge rate of rainwater and sewage is 1 to 3 times that of the 

traditional inspection wells.

Application:

    Used for the design, construction and maintenance of plastic drainage check well projects within the scope of building districts (residential areas, public building areas, factories, etc.), urban and rural municipalities, industrial parks, and old city renovation.
