reporter learned from Changzhou New Taipei District yesterday that in order to cooperate with the implementation of the full coverage project of sewage collection and treatment in New Taipei District, the first phase of the maintenance of the existing sewage pipeline network in Changzhou New Taipei District, led by Changzhou Xinmei Water Co., Ltd., was recently completed. Through innovative use of robot "physical examination" and "minimally invasive" surgery and excavation and repair, a total of more than 1,500 defect points were repaired.
robot "physical examination" to form an accurate digital report
It is reported that the project officially entered the site on May 11 this year, covering the sewage pipeline inspection, testing, repair and reconstruction work in the three areas of Menghe Town, Xixiashu Town and Chunjiang Town, New Taipei District, Changzhou. A total of 152.1 kilometers of pipeline network was inspected in the early stage, and more than 1,500 structural defect points of sewage pipeline network were found. If repair is not done in time, these defects will cause blockage, leakage, cracking, etc. of underground drainage pipelines, or long-term leakage and surrounding soil erosion, resulting in deformation and collapse of pipelines, underground drainage pipelines will lose their drainage effect, and sewage outflow affects the surrounding environment. During the implementation of the project, maintenance personnel introduced a small, exquisite, mobile and flexible miniature "robot" of the CCTV detection system of the pipeline, drilled into the narrow and dark drainage network to conduct a comprehensive "physical examination" of the pipeline, scanned and analyzed to obtain clear and accurate data, and formed a digital report.
adopts symptomatic measures, combining "minimally invasive" surgery with excavation and repair
analyzes and judges each defect point according to the digital report, and efficient construction is carried out using a combination of excavation and non-excavation. During the construction process, UV curing repair UV-CIPP solutions are innovatively adopted to implement "zero excavation" repair for pipelines with less serious damage but with structural and functional defects. The use of this technology shortens the construction cycle and reduces maintenance costs, and greatly reduces the impact on the surrounding environment and traffic due to the lack of excavation of the road surface.
For severely damaged pipelines, excavation and reconstruction are used to strengthen the original pipeline externally or replace it with new sewage pipes. In order to reduce the impact of pavement excavation on surrounding residents, Xinmei Water Engineering Management staff checked the situation of the construction site at each area in advance, connected with local townships and excavation procedures, actively coordinated relevant contradictions, and ensured that the project continued to advance. At the same time, in order to ensure the overall progress, quality and safety of the project, we have followed the daily progress of the project in the form of a daily report, and carried out safety warnings, noise reduction and dust reduction measures, the project location has also won the honorary titles of Changzhou Civilized Standardized Construction Site and other civilized chemical construction sites.
should be repaired and the sewage collection rate will be significantly improved. According to the principle of repairing and repairing, Xinmei Water has eliminated a series of key safety hazards in the promotion of the project. Through monitoring of the Menghe Pump Station, the second-level lifting pump station with the largest daily centralized sewage treatment, found that the month-on-month growth rate of sewage collection rate in September was 109.8%, the operating water level dropped by 2 meters, and the sewage collection efficiency was significantly improved, providing a solid facility foundation for the unified operation and maintenance of sewage pipelines in New Taipei District and centralized and efficient sewage treatment.
At present, Xinmei Water has completed the inspection of existing rural sewage treatment facilities, and will carry out comprehensive maintenance of rural sewage treatment facilities in the next stage.
