黔南州某综合楼给排水及热水系统设计_毕业设计.doc

本设计是黔南州某综合楼给排水及热水系统设计，设 设 计 总 说 明 本设计是黔南州某综合楼给排水及热水系统设计，设计的主要内容包括：给水系统、排水系统、屋面雨水系统和热水系统四个部分。 本工程为高层综合楼，建筑高度为57. 0米，共十四层，地下一层为车库，地上十三层为宾馆客房和办公用房。 建筑以城市给水管网作为水源，建筑东侧龙山大道上有一根DN150的市政管网，供水水压为0.35MP，市政管网不允许直接抽水。经技术经济比较，给水系统采用分区供水方式，一至三层为低区，由市政管网直接供水。四层到十三层为高区，采用变频泵给水。 排水系统采用的是污、废分流制，底层单独排水。污水经化粪池处理后排入城市管网集中送至城区集中污水处理厂，市政排水干管DN400，管底埋深2.5~3.0m。 雨水系统采用外排水系统，设雨水斗和立管，雨水斗采用重力流雨水斗。 该建筑的功能决定了其对热水供应的要求很高，所以采用集中全天热水供应系统，冷水通过半容积式加热器采用机械循环系统加热后，经热水管网送到个用水点，为保证任何时刻均达到设计水温，设计采用半容积式加热器。 关键词：建筑给水系统，排水系统，热水系统，雨水系统 注：本设计来源于生产实际。 Introduction of design This design is a complex building Qiannan drainage and hot water system design, the design of the main contents include: four parts of water supply systems, drainage systems, roof drainage systems and water heating systems. This works for high-rise building, building height of 57.0 meters, a total of 14 floors, the basement is garage, on the ground thirteen of hotel rooms and office space. Construction of urban water supply network as a source, eastern side of the building there is a DN150 municipal pipe network Longshan Avenue, water pressure of 0.35MP, municipal pipe network does not allow direct pumping. Through technical and economic comparison, the water supply system is partitioned water supply, one to three for the lower area, directly from the municipal water supply pipe network. Four to thirteen area high, variable frequency pump water supply. Drainage system is used in sewage, waste diversion system, the underlying drainage alone. After the sewage discharged into septic tanks to the distribution network focused on urban centralized sewage treatment plants, municipal drainage main pipe DN400, tube bottom depth of 2.5 ~ 3.0m. Rainwater drainage system with external systems, set up water bucket and risers, gravity flow water bucket water bucket. The building features a high determines its water supply requirements, so a centralized all-day hot water supply system, heating system circulating cold water through semi-mechanical displace
