Cleaning and maintenance techniques of plastic inspection wells

塑料检查井因为埋在地底，管道的检查需要通过专门的工具进行。常用的检查方法有：

Because the plastic inspection wells are buried in the ground, the inspection of the pipelines needs special tools. The commonly used methods of inspection are:

反光镜检查——利用操作杆杆和反光镜组成，深入到井座，通过不同角度的反射来检查管道时候有淤泥，淤泥量，淤泥位置等情况，特点：简单方便。

Reflective mirror inspection - the use of operating rod and reflector, deep into the well, through different angles of reflection to check the pipe, silt, silt, silt position and other conditions, characteristics: simple and convenient.

电视摄影检查——有电缆和电视摄像机组成，摄像机安装在可移动的小车上，通过控制移动摄像机，检查人员可以通过摄像内容来了解管道情况。特点：拍摄真实，避免光、角度的影响。

Television photography - there are cable and television cameras. The camera is mounted on a removable car. By controlling the mobile camera, the inspector can understand the pipeline through the video content. Characteristics: shooting the real, avoiding the influence of light and angle.

检查管道淤泥情况，应采用检查镜目测，不得下井探测。

Inspection of pipeline silt should be inspecting by inspection lens and not downhole detection.

清掏工具的选择

Choice of cleaning tools

雨水检查井内淤泥、沙的清掏，宜采用机械吸泥工具实施清理。雨水检查井是属于有沉泥塑料检查井，它的底端有专门的沉泥室，经过雨水的冲刷、沉积，可能会推挤泥沙。通过专门的机械吸泥工具清掏效率高，安全性高。避免了人工清理费时费事的确定。在有些情况下需要采用人工清理，这时候也需要采用专用清掏工具。

Dredging of mud and sand in rainwater inspection wells should be carried out by mechanical mud suction tools. Rainwater inspection well is a kind of plastic inspection well with sediment. It has a special sediment chamber at the bottom. After the erosion and deposition of rainwater, the sediment may be pushed. Through special mechanical mud suction tools, the cleaning efficiency is high and the safety is high. It avoids the time and trouble of manual cleaning. In some cases, manual cleaning is needed. Special cleaning tools are also needed.

检查井的清理方式

The cleaning method of the inspection well

通过检查、选择清理工具之后，就可以进行清理。清理的方法可以有：

After checking and selecting cleaning tools, you can clean up. The methods of cleaning up can be:

充气管塞封堵法——由操作杆、充气软管和充气管塞组成。经充气软管将充气管塞冲满气，然后利用操作杆来进行控制，进行清理。可进行全面清理，清理质量高。

The plugging method of inflatable pipe plug is composed of operation lever, inflatable hose and inflatable tube plug. The inflatable tube is filled with gas through the inflatable hose, and then the control rod is used for controlling and cleaning. It can be cleaned up in an all-round way and the cleaning quality is high.

高压冲洗法——由高压冲洗软管和高压冲洗喷嘴组成。利用高压来进行清理，这种方法适合清理体积小的物体。

High pressure flushing method consists of high pressure flushing hose and high pressure flushing nozzle. The use of high pressure to clean up, this method is suitable for cleaning small objects.

钢棒清通法——适合清理体积大的废弃物，通过钢棒清理可有效的疏通。

Steel bar dredging method is suitable for cleaning up large volume of waste, cleaning through steel rods can effectively dredge.
