Inspection wells are an essential part of construction and urban infrastructure. It is a facility used to connect sewers and drainage systems, and is used to inspect, maintain and repair sewer pipes. In addition, it can also be used to prevent the water from flowing too fast, which will cause the sewer water to diverge. In this article, we will learn more about the definition, purpose, classification, and common problems of the inspection well.

1. Definitions

inspection well is a generally used to create convenient artificial hole, located in the sewer system node, the main function is to change the direction of the discharge of water, so that the pipeline can be maintained and cleaned. In construction, it is usually installed in a water pump room in an underground toilet or toilet; in urban infrastructure, most inspection wells are located on the side of the road or in the center.

2. Use

inspection wells are usually used in the following aspects:

(1) Convenient inspection: It can easily enter the sewer and perform inspection and maintenance when necessary.

(2) is convenient for sewage discharge: it can change the direction of sewage discharge and discharge peculiar smell and various sewage.

(3) is easy to repair: it provides convenience for the maintenance and repair of sewer pipes.

(4) to prevent bifurcation flow: can slow down the flow speed, to avoid the sewage water flow bifurcation flow.

3. Classified

According to different needs and uses, inspection wells can be divided into the following types:

(1) includes circular, rectangular, triangular and other shapes;

(2) is classified by material, including cement inspection wells, glass fiber reinforced plastic inspection wells, cast iron inspection wells, etc.;

(3) is divided into shallow wells and deep wells according to depth.

4. Frequently Asked Questions

In the process of using the inspection well, they will also encounter some problems, such as:

(1) odor problems in the inspection well;

(2) water inflow problems in the inspection well;

(3) water overflow problems in the inspection well.

In response to these problems, we provide the following suggestions:

(1) Clean and maintain the inspection well regularly to prevent odor problems inside.

(2) The excessive water intake of the inspection well may be caused by sewer congestion or rainy weather, which can be solved by cleaning the sewer or installing drainage equipment.

(3) In rainy weather or when the displacement is too large, the overflow of the inspection well is a common problem. You can choose to connect it to the sewer or add anti-overflow equipment in the inspection well. By understanding the definition, use, classification and common problems of inspection wells,

can not only better maintain and use it, but also better protect our urban infrastructure. If you need to install or maintain a manhole, consult a professional.
