Description

  The present invention relates to an indoor temporary piping line used when renewal work or repair work of a water supply pipe laid in a multi-storey building such as an apartment house, a school, a hospital, a building, etc. The present invention relates to a management and supply system for an indoor temporary pipeline. More specifically, each of the constituent members such as straight pipes, cheeses, elbows and the like forming the indoor temporary piping path is unitized into a temporary piping unit, and the temporary piping units are connected to each other by a joint, thereby providing an indoor temporary piping path. Can be formed easily and quickly, and the construction period can be greatly shortened, and after use, the temporary pipe line for indoor use can be disassembled very easily, and almost all disassembled temporary pipe units and Each part such as a joint can be reused to save resources, prevent pollution caused by waste, and prevent environmental pollution. In addition, each part such as a temporary pipe unit or joint that forms a temporary pipe line for indoor use can be used.

  In general, in water supply pipes laid in buildings such as apartment buildings, schools, hospitals, buildings, etc., rust generated in water supply pipes such as galvanized steel pipes when used for many years. As a result, the outflow of red water, slimming of pipes, generation of bacteria, decrease in flow rate and water pressure, outflow of scale, etc., resulting in water quality deterioration and sanitary problems, water leakage accident due to deterioration of packing, etc. Various negative effects will occur.

  In particular, in a housing complex, a water utility (water department) does not directly manage the water supply pipeline, and the management is usually left to the management company or the owner of the housing complex. As a result, maintenance and management of water supply pipes will become insufficient, and as a result, aging of water supply pipes has progressed more than expected due to secular change, and in order to meet the demand for safe and reliable water supply, It is necessary to renew it in the waterworks pipeline.

  In addition, due to the growing demand for safe water, there is an increasing need to switch the water supply method for apartment buildings from the tank pumping method to the direct pressure water supply method. Is increasing.

  By the way, in the renewal of the water supply pipes laid indoors such as in a housing complex, there is a resident's life, so the renewal of the pipe line due to water outage is not allowed. For this reason, in the conventional renewal work of water supply pipes, a so-called temporary pipe line construction method is employed (see, for example, Patent Document 1 and Patent Document 2).

  In general, in the temporary piping line in the renewal work of the water supply pipe, a vinyl pipe, a polyethylene pipe or the like that is light in weight and excellent in handleability is widely used instead of a metal pipe such as a steel pipe. Moreover, when laying a temporary piping path using a vinyl pipe, the adhesive is used for the connection of vinyl pipes, and the permanent connection is performed.

However, when vinyl pipes are used, there is a problem that not only does it take time to join the vinyl pipes, but a considerable time is required from the completion of the joining to the start of water supply.
In addition, the temporary piping line must be cut to remove the temporary piping line, and the pipe must be cut. This consumes time and labor, and the pipe cannot be reused. Therefore, it is necessary to dispose of all the forming members, and there are many problems in resource saving and environmental conservation.

  Furthermore, the management of indoor water supply pipelines is left up to the management company and the owner of the apartment house, so the construction management at the time of renewal of the water supply pipelines is also left to the contractor, resulting in performance and hygiene. It is unclear whether or not high-quality components that are sufficiently controlled in terms of use are used, and there is a problem that costs and time required for renewal are unclear and lack of service to the residents.

  In addition, when receiving orders and construction of temporary pipelines, design temporary pipelines and create construction drawings, estimate construction costs, prepare, carry in and manage pipeline components, inventory management of pipeline components, and completion of construction Since most of the subsequent removal of the temporary pipelines is performed manually, it is difficult to significantly reduce the cost of the temporary pipelines, resulting in a problem that the cost of renewing the water supply pipelines increases.
