Description

Integrated water supply system for existing building reconstruction

Technical Field

The utility model belongs to the technical field of building reconstruction, and particularly relates to an integrated water supply system for existing building reconstruction.

Background

In the existing building, the water supply system generally has the problems of water quality reduction caused by pipeline aging, insufficient water supply pressure, insufficient flow and the like caused by water supply facility aging, abrasion and the like. To solve the above problems, the water supply system in the existing building is generally upgraded and modified.

The common current water supply system is modified by the following steps: after the current building water supply system is shut down and water is drained, old pipelines such as current stand pipes of the building water supply system are removed; re-punching holes on each floor slab of the original crossing pipeline in the building, re-arranging steel sleeves, and fixing by adopting concrete; cutting and connecting new pipelines and pipe fittings to be replaced when the concrete at the sleeve is solidified, and fixedly mounting new pipe clamps by expansion screws and the like; after all the pipelines of each household in the building are completely reinstalled, pipeline sterilization, pressure test and the like are carried out; and recovering or maintaining the indoor suspended ceilings and cabinets affected by the transformation. However, in the conventional construction water supply system reconstruction project implementation, there are generally problems of lack of reconstruction space, long construction period, inconvenience in maintenance after reconstruction, large influence on current living population, and more associated damage to the reconstruction of current indoor water supply system.

In addition, in the current situation, as the life quality of people is improved in old residential communities without the secondary water supply system, water supply appliances are updated, water flow and pressure requirements are increased, and the problems of insufficient water supply pressure and flow generally exist in high floors of the old communities.

As the end of the pipe network, residual chlorine is insufficient, which results in the situation that the bacterial content in the pipe network is potentially higher than the national relevant standard requirement.
