Pipeline non excavation UV curing repair seeks Changyou Repair Technology Company

It is an important livelihood project. According to the rainwater and sewage diversion and drainage plan in the old urban area of Yancheng City, the areas that will undergo diversion renovation in 2019 include Beicheng Street, Dongcheng Street, Xinjie Street, Jiefang Street, Heping Street, and Hedi Road, totaling 7 streets. The total length of the construction pipeline network is about 6000 meters (excluding the household branch pipeline), and the pipeline network will use D300-D600 meter diameter PE steel strip corrugated pipes. The total investment of the project is about 18 million yuan. The entire project is planned to be implemented annually and in stages, based on the overall principle of "main streets first, then streets. Avoiding traffic congestion. Improving suburban functions is an inevitable requirement. The project is scheduled to be completed in 2019. Traffic needs to be closed before excavating the roadway. During the implementation of the rainwater and sewage diversion renovation project in the old city streets, it is important to remind citizens that it is difficult to install sewage pipes on sidewalks and that the foundations of residential houses along the street are shallow because some streets in the old area are narrow. Ultimately, the diversion of rainwater and sewage in the old suburbs is also an important measure to fundamentally improve the black and odorous water bodies in rural areas. The suburban rainwater and sewage diversion renovation project is to build ecological civilization suburban back streets and alleys, ensuring the personal and property safety of citizens. Construction of non excavation repair technology for pipeline networks. Pedestrians and vehicles are advised to pay attention to the construction signs or choose to take a detour to the southern section of the municipal UV curing repair plan, CIPP-UV curing repair method for pipelines, and resin lining curing repair technology for pipelines.

No need for full excavation, the construction length can reach 1000-1500 meters at a time. The construction period is short, and maintenance is not required. It can be repaired and put into operation immediately to improve the pressure resistance strength of the pipeline. The inner lining layer is continuous, without weak points that are prone to corrosion, low friction, no scaling, and no bacterial growth. It is suitable for DN100-DN1600

Non excavation point repair of rural pipelines, also known as local resin curing method, refers to a circular local repair method that uses a universal point repair airbag expansion method at the location where the original pipeline is to be repaired. The fiberglass fabric uniformly impregnated with curing resin is tightly attached to the pipeline repair site, and after curing at room temperature, it forms a local short pipe lining. Analysis of non excavation point repair materials and equipment: fully imported high-temperature resistant and chemically resistant universal silicate resin is selected. This product has the ability to adapt to high and low temperatures, and does not contain volatile organic polymer substances (excluding styrene). The material is insufficient to shrink (<0.6%); After testing, it has been proven that the product has a lifespan of over 50 years (10000 hours of testing). Silicic acid resin belongs to room temperature curing resin, and the curing time is generally around 1 to 2 hours. The curing time can be adjusted according to specific circumstances, and in actual construction, it will not affect the construction quality due to the presence of a small amount of residual water source in the pipeline. The resin is divided into two groups: a-bs616 and b-bs617. The cured material has high hardness, good toughness, strong impact and bending resistance, and also has very strong corrosion resistance.

Pull the hose into the pipeline to be repaired from the inspection well, use water or air pressure to round the hose, and solidify it to form a sturdy and smooth new pipe, achieving the purpose of repair. From the situation of repairing old pipes abroad, it can be seen that due to the strong adaptability and reliable quality of this technology, the use of inspection wells can achieve a shovel of soil without moving, which is truly non excavation and has been widely applied in the repair of sewage pipelines. Afterwards, the inner layer of the soft lining tube soaked in resin is flipped over to the outside using water pressure or air pressure, and bonded to the inner wall of the old tube. When the soft lining pipe reaches the end point, hot water or steam is immediately injected into the pipe to solidify the resin, forming a hard lining with anti-corrosion and anti-seepage functions that closely adheres to the inner wall of the old pipe. The flexibility and internal pressure of the resin tube before curing can fill cracks, cross gaps, and bypass curved sections. After the resin is cured, the soft lining tube forms a new tube with a shape consistent with the original tube and a slightly smaller inner diameter than the original tube. 2) The CIPP pull in resin lining method uses non-woven felt hoses with anti-seepage films. Also known as Original Curing Process (CIPP)

The industry standard "Technical Regulations for Non excavation Repair and Renewal Engineering of Urban Drainage Pipelines" (CJJ/T210-2014) issued by the Ministry of Housing and Urban Rural Development defines in-situ curing method as a repair method that uses flipping or pulling to place an impregnated resin liner into the original pipeline, and after curing, forms the inner lining of the pipeline.

In situ curing (CIPP) can be divided into three curing processes: hot water curing, steam curing, and ultraviolet curing. Hot water and steam curing methods are widely used due to their long history. UV curing technology has gradually been widely applied due to its advantages such as thinner inner lining wall thickness and shorter curing time under the same conditions. According to statistics, UV cured lining accounts for 63% of lining construction in Germany and 50% of the market in Europe. At present, this technology is flourishing in China and will inevitably replace hot water and steam curing technology.
