Problems solved by technology

The traditional reconstruction and expansion process has long construction period and great impact on the environment.
In addition, in recent years, due to the imperfect construction of the underground drainage pipe network system and insufficient experience in system management, urban floods and waterlogging accidents have occurred frequently in my country, urban areas have accumulated water for a long time, roads are blocked, and traffic order is chaotic, which seriously affects the daily travel of the people. Safety

Embodiment

[0029] figure 1 It is a flow chart of an embodiment of a partial resin curing construction process for the reconstruction and expansion of a drainage pipe network according to the present invention. As shown in the figure, the present invention provides a partial resin curing construction process for the reconstruction and expansion of a drainage pipe network, which includes the following steps:

[0030] (1) Preliminary investigation: Conduct CCTV inspection or QV inspection for those without inspection data in the early stage to judge the defects of the pipe section, and use CCTV to inspect and review the internal conditions of the pipeline before repairing.

[0031] (2) Apply for road occupation: According to the design drawings and site survey results, report the corresponding road occupation and structures to be demolished to the supervisor and construction unit.

[0032] (3) Sealing: During the repairing construction of the pipe section, the pipeline is safely blocked, an...

Abstract

The invention discloses a local resin curing construction process for reconstruction and extension of a drainage pipe network. The process comprises the following steps of checking at the early stage;applying for occupying a road; plugging by adopting an air bag plugging method or a wall plugging method as a plugging method; guiding flow; clearing and dredging a pipeline and performing CCTV detection; pretreating the pipeline; curing and repairing local resin and performing CCTV detection, specifically, a felt cylinder is soaked with resin, the felt cylinder is wound on a air bag, the air bagreach a repairing place under the guidance of the CCTV, the air bag is inflated to enable the felt cylinder to patch to be pressed and coated on the pipeline, the pressure is kept until the resin iscured, g the air bag is released the pressure to shrink and pulled out the pipeline, finally the CCTV detection is performed, and construction quality detection is performed; and cleaning up a site. The method is simple and rapid in construction, meanwhile, shortens the construction period, increases the strength of the pipeline, achieves the purpose of repairing, can protect the environment, saves resources, does not dig a road surface, does not generate garbage, does not block traffic, and greatly improves the image of pipeline repairing construction.

Description

technical field [0001] The invention relates to the technical field of drainage pipe network construction, in particular to a partial resin curing construction process for the reconstruction and expansion of a drainage pipe network. Background technique [0002] With the acceleration of the urban modernization process, the drainage pipe network, as an important municipal facility, plays an important role in the city's "blood vessels". However, at the beginning of urban construction, the pipe network was not systematically planned, and there were problems such as broken ends and mixed rain and sewage. With the passage of time, some pipes began to have structural defects such as pipe aging, rupture, leakage, deformation, and trees. Root, silt and other functional defects. Cause urban waterlogging, polluted rivers and other problems, affecting people's lives and environmental problems. Therefore, it is imminent to rebuild and expand the municipal drainage pipe network. The t...
