Glass fiber reinforced hose

Technical Field

The utility model belongs to the technical field of the pipeline, concretely relates to glass fiber reinforced hose.

Background

The town underground pipeline is used as a 'lifeline' of the town to directly participate in the operation of the town. Underground pipelines are extremely important urban public infrastructure, and whether the underground pipelines can normally play the design function directly influences the safety of cities and towns and the sustainable development of society, economy and environment.

However, with the increasing service life of underground drainage pipe networks, the aging and overhauling phenomena are serious, the diseases such as leakage, corrosion, cracking and silting are ubiquitous, and the safe operation of the urban underground drainage pipe networks with huge scales faces a serious challenge. According to statistics, the leakage of sewage in a black and odorous water body and a drainage pipe network is one of main inducements of urban water body pollution, and in addition, the leakage of a pipeline can cause a large amount of underground clear water to permeate into the pipeline, so that the sewage concentration in the pipeline is greatly reduced (the COD concentration is less than 100mg/L), and the treatment efficiency of a sewage plant is seriously influenced; the insufficient drainage capacity of the pipeline caused by diseases such as siltation, scaling and the like due to the fact that the underground drainage pipe is maintained inefficiently in the future is one of the main reasons for frequent urban waterlogging; the excavation of soil around the pipe body and the reduction of the structural performance of the pipe body caused by the leakage, corrosion and other diseases of the drainage pipe network are the root causes of frequent collapse accidents of municipal roads. In recent years, urban road collapse accidents frequently occur, which causes injuries and deaths of many people and huge property loss.
