Study On Optimization Design Of Outdoor Water Supply Network System For Residential Parks In Yinchuan City

Yinchuan is the rise of the western new city, as the capital city of Ningxia Hui Autonomous Region in recent years to accelerate the pace of construction, the urban population is growing every year, urban water consumption is also progressively increased. City scale expansion and modernization of the continuous improvement of urban water supply areas are expanding the existing urban water supply system relatively stable water conditions undergone great changes.This requires that the designer must comply with national guidelines, policies, laws and regulations, uniform construction standards, improve the quality of engineering design, so technologically advanced, safe, reliable, economical, easy to manage, but also the range for residential new construction, expansion or remodeling water Supply project.The water supply engineering design requirements from a global consideration of the conservation and utilization of water resources, water environment protection and water resources sustainability, correctly handle the relationship between water and other water district residents of summary, the norms and practice, according to the outdoor cell water supply network, it proposed direct municipal residential outdoor water supply network and pressurized water supply pipe network combines optimal design. Analysis of the cell life pond, fire water alone to establish the feasibility and advantages put forward reasonable proposals. Investigation by the cell water, outdoor water supply network analysis cell design flow proposed calculation method is simple and accurate analysis of the residential outdoor water supply network design flow calculation process, providing cell pressure pumps Optimization Selection of parameters.Focus on the completion of residential domestic water supply system and outdoor fire water pipe network system design, proposed residential domestic water supply system uses municipal water supply a combination of direct supply of pressurized water supply system, fire control network proposed outdoor water supply network in combination with the residents of the optimization program for select the urban community domestic water supply system to provide a reference, to provide reference for selecting residential fire water supply system for residential outdoor water supply network design flow calculation provides calculation realistic, we propose a simple economical and practical outdoor water supply network design Program. The design objects Yinchuan City, a residential area, combined with the actual situation of the cell, complete community living water, outdoor fire water pipe network design and green water, the design range of the pipeline between residents from the municipal pipe network.Network design to material appropriate design specifications and construction units to provide the basis for the design of outdoor water supply, fire water and share a set of green water pipe network system. The main task is to design the pipeline arrangement associated hydraulic calculation of water supply pipe network and life and fire water meter wells to the choice of accessories. Design of the main chart includes a pipe network layout plan, valves, water meter installation large drawing, water wells a large drawing, a bill of materials engineering.
