Embodiment 1

[0026] 1. The detection method of urban groundwater drainage network, including the following steps,

[0027] S1. Select the inspection area, determine the length of the underground pipe network to be inspected on the ground, and open the manhole cover between the underground pipe network for inspection;

[0028] S2. Clean the underground drainage pipe, clean the inner pipe wall of the underground drainage pipe to meet the testing requirements;

[0029] S3. Detect the underground drainage pipe, put the urban underground drainage pipe network detection device into the pipe, and control the urban underground drainage pipe network detection device to detect the underground drainage pipe wall;

[0030] S4. Record the location. When the urban underground drainage pipe network detection device detects problems such as damage to the underground drainage pipe network, record the location of the damage and prepare for the subsequent repair work. It can realize the unrestricted detectio...

Embodiment 2

[0032] On the basis of Example 1, in the S2 cleaning of the underground drainage pipeline, a water blocking air bag is placed upstream of the underground drainage pipeline, which can temporarily block the drainage in the underground drainage pipeline and avoid the impact of sewage in the underground drainage pipeline on the detection. accuracy.

Embodiment 3

[0034] On the basis of Example 1, in the S2 cleaning of underground drainage pipes, after the underground drainage pipe network water blocking process is completed, the urban underground drainage pipe network detection device is placed to clean the underground drainage pipe network pipe wall, and the high-pressure water The cleaning gun head enters from the upstream detection wellhead and moves to the downstream detection wellhead to clean repeatedly until the pipeline meets the detection requirements, which can realize the cleaning of the silt accumulated in the underground drainage pipe network all the year round and improve the detection accuracy.

Abstract

The invention relates to the technical field of water supply and drainage, in particular to an urban groundwater drainage pipe network detection method. The method comprises the following steps of selecting an detection area, determining the length of an underground drainage pipe network to be detected on the ground, opening a corresponding well cover of the underground drainage pipe network to bedetected, cleaning an underground drainage pipeline, cleaning the inner wall of the underground drainage pipeline till reaching a detection requirement, inspecting the underground drainage pipeline,placing an urban underground drainage pipe network detection device in the pipeline, inspecting the inner wall of the underground drainage pipeline by controlling the urban underground drainage pipe network detection device, recording a damaged location when the damage like problem of the underground drainage pipe network is detected by the underground drainage pipe network detection device, and preparing for post repair work. By means of the detection method, the problems that detection distance in the prior detection art is short, the positioning is difficult, and the damage detection is notcomprehensive are solved.

Description

technical field [0001] The invention relates to the technical field of water supply and drainage, in particular to a method for detecting urban groundwater drainage pipe networks. Background technique [0002] Urban drainage pipe network is an indispensable and important infrastructure for modern cities, a basic industry with overall and leading influence on urban economic development, the backbone of urban water pollution prevention and control, urban drainage and flood control, and an important indicator to measure the level of modern cities. sign. For various pipelines buried under the road, due to the vibration of road vehicles, the poor foundation of the pipeline itself, and the influence of corrosive sewage and harmful gases, underground pipelines will have cracks, damage, dislocation of pipe joints and internal corrosion. Timely detection, maintenance and cleaning of pipelines may cause accidents and cause unnecessary losses. However, the environment where the pipel...
