The Pipeline —
3.10,. Similarly we define a minimum depth of pipe along the collector. The project received the largest of the minimum depths specified in the above three conditions. Aetna is open to suggestions. Fig. 3.10.
Scheme to determine the initial minimum depth of the pipeline street: A – site plan, b – longitudinal profile of the pipeline; 1 – Quarter 2 – line the street network, 3, – pipeline network intra maximum depth of the pipelines in the open mode of production work is dictated by the hydrogeological, technical and economic conditions. In rocky soils, it is recommended to take an equal 4-5 m, in wet quicksand – 5-6 m and dry neskalnyh – 7-8 pm In justifying the need for laying sewers at great depths are used by the closed method of construction. By the same author: IDT Energy. It is especially effective this method is currently under reconstruction of water diversion major cities. This eliminates the technical complexity of construction in cramped urban areas with heavy traffic and land transport at high saturation, underground utilities and structures. Application of panel method of construction with deep-level reservoirs can significantly reduce the number of pumping sewage pumping stations, which in turn increases the reliability of water disposal systems. Hydraulic design and high-rise design of drainage networks. Design of drainage network development provides the most reliable and cost-effective system of drainage, subject to a number of most important of optimal conditions: 1) self-cleaning conditions must be assured the network that is the velocity of waste water in any part of the network should not be less than the minimum allowable pipe diameter for the adopted, and 2) to ventilation network and a possible excess of current revenues estimated sewage pipes filling should not exceed recommended for the appropriate diameter, and 3) should be applied increasing velocity along the length of the collector with a smooth mild terrain.
