High-quality drinking water engineering and secondary water supply reconstruction engineering combined reconstruction method

Abstract

The invention discloses a high-quality drinking water engineering and secondary water supply reconstruction engineering combined reconstruction method. The method comprises the following steps that pressurizing pipelines are reserved in a pump house; the middle area pressurizing pipeline is connected; the low area pressurizing pipeline is connected; and roof preservation treatment is performed. According to the method, compared with a regular three-area three vertical pipe down-feed method, the space of all middle area vertical pipes can be saved, and conditions are created for vertical pipe construction. According to the high-quality drinking water engineering and secondary water supply reconstruction engineering combined reconstruction method, a prior water supply system can be maintained before secondary water supply reconstruction by reserving valves and the pipelines, the prior water supply system can be directly switched into a separated area system after secondary water supply reconstruction is completed, through a middle-low area down-feed and high area water adding box bypass pipe up-feed water supply mode, the pipeline occupied space is saved, water supply safety can be guaranteed, the long-term abandoned amount is small, and system switching is convenient.

Description

technical field [0001] The invention belongs to the field of residential water supply pipe network reconstruction projects, and in particular relates to a transformation method combining high-quality drinking water projects and secondary water supply transformation projects. Background technique [0002] With the rapid development of my country's economy, the pressure on the pipe network is increasing and it is overwhelmed. Leakage has become a common phenomenon in the water supply pipe network. All over the country, the curtain of pipe network transformation in residential areas has been opened. The high-quality drinking water project is the first batch of projects for the renovation of the community's pipe network. The renovation content includes the current buried pipelines, the exposed pipelines before and after the pump room, etc., but only touches are given to the existing pools and water tanks in the community, and the pump room and other secondary The secondary wate...

AI Technical Summary

Problems solved by technology

[0004] (1) Time mismatch

Since the secondary water supply reconstruction project obviously lags behind the high-quality drinking water reconstruction project, if the design of the original water supply system of the community is maintained for high-quality drinking water, it will inevitably fail to meet the requirements of the secondary water supply reconstruction project, which will lead to a large number of abandoned projects;

[0005] (2) The booster pump does not match

Since the transformation of the secondary supply and the upgrading of drinking water are not synchronized, and the renovation of the pump room is not included in the category of drinking water quality, if the domestic water tank is forcibly canceled during the transformation of drinking water quality, there will be a greater risk of water use. The current power frequency pump Opening and closing for a long time will lead to an increase in the electricity bill of the property, and second, it will lead to a decrease in its own life, and there is a risk of burning

[0006] (3) The site is limited, and there are not too many placement positions for the riser

[0008] Since the secondary water supply renovation project is a new project, most provinces and cities focus on high-quality drinking water projects for community renovation, and rarely involve the combination of high-quality drinking water projects and secondary water supply renovation projects. With the development of cities, the secondary Water supply renovation projects will be gradually popularized from first-tier cities. If the two projects cannot be effectively combined, it will bring many risks
