Doha South Sewage Infrastructure Programme | Jacobs-正规博彩十大网站排名

近年来，卡塔尔国的经济以每年两位数的速度增长. 国家首都多哈将成为2022年世界杯足球赛的主要主办城市, 需要大量的准备工作来提供和维护一流的高速公路网络, utilities and related services.

Additionally, 卡塔尔国制定了《正规博彩十大网站排名》，设想通过实施复杂的工程项目，为快速增长的公民和居民提供世界级的、最先进的和更新的首页，从而实现首页的不断升级.

这些因素导致了大量的项目，所涉及的工作的复杂性，因此对国家公共工程管理局(Ashghal)的资源提出了前所未有的需求。.

其中一项努力是多哈南部污水处理首页计划(DSSIP)，该计划以前被称为多哈内部污水处理实施战略(IDRIS)计划, a world-class solution developed by Ashghal, 改善和扩建污水收集首页，以应付未来80年预计的人口增长.

雅各布斯目前担任DSSIP项目的项目管理和建设监督顾问, 其中包括升级和扩建多哈最古老的集水区的污水首页, which is becoming overloaded due to the scale and pace of development. 一项主要的隧道拦截系统计划正在取代现有的浅层污水渠和多个抽水站，以满足这个不断增长地区的长期需要.

The Doha South Sewage Infrastructure Programme was our first key program in Qatar. It’s been a great journey with Ashgal, driving innovation including how deep sewage systems are built and operated. 如果没有阿什格尔的远见卓识和领导才能，这个项目是不可能实现的. And we’re proud to be a part of the program.

Modernizing Doha’s sanitation system for tomorrow

多哈南部污水处理首页计划(DSSIP)是由Ashghal开发的世界级解决方案，旨在升级和扩大其污水处理首页，并适应未来80年预计的人口增长.

原来的DSSIP计划包括横向截流污水渠，用于截流污水，并纾解现有超载的系统及其众多泵站的压力. 在重力作用下，污水将通过主要的污水干渠输送，并向南输送45公里，到达隧道下游的终端泵站, then lifted to the new Doha South Sewage Treatment Works. 这些污水将作为处理过的污水污水回收利用，并与适合灌溉用途的处理过的水一起返回多哈地区.

Jacobs, 作为项目管理顾问和“工程师”，管理Ashghal和负责项目交付和提供总体项目监督的各方之间的接口.

Ashghal appointed Jacobs to manage the whole program, from inception to handing over, and ensure that the desired program objectives of health and safety, quality, cost and schedule are achieved.

About the program

The original program includes several packages:

Main trunk sewer tunnels, 重力排水主干渠45公里，内径3至4不等.5米，这将连接多哈南部的一些地区和污水管网. The deep trunk sewer is also comprised of 26 deep shafts. 主要的污水干渠将通过一个深泵站将污水流输送到现有的多哈南部处理厂, 对污水处理厂和输送系统的异味进行全面控制，减少对环境的影响, 减少现有排水管网因水压过大导致污水溢出所带来的其他环境问题, where sewage flows exceed its capacity.
侧向截流污水管道长达70公里，使用超过250个竖井 , which will convey flows from areas in the center of Doha, Wakra-Wukair and Mesaieed to the main trunk sewer tunnels.)
位于新多哈南污水处理厂的终端站，是世界上最大及最深的污水泵站之一.
Treated sewage effluent (TSE) pumping stations.
TSE return mains.
New Doha South STW, with state of art treatment technology and an initial treatment capacity of 500,000 m3/day and ultimate built-out capacity of 1 Million m3/day.

该团队在这个项目中采用的一些突出和创新的解决方案包括:

集成管片衬砌的使用，结合了防腐衬砌和分段衬砌的应用. 这种方法节省了时间，并完全消除了二次隧道衬砌现浇施工操作的需要.
Use of Vertical Sinking Machines, for the first time in the region, to construct deep shafts in the congested areas for minimum disruption to public.
利用先进的土压力平衡掘进机考虑复杂的地质和高度约束的时间表.

Award-winning delivery

深干渠隧道，DSSIP主要干渠MTS-01项目，获得了认可 Engineering News-Record’s 2019 Global Best Project in the Water/Wastewater Category. MTS-01 is also the first project in the region to achieve CEEQUAL’s Design and Build Good Rating Certification. Also, CEEQUAL在水环境和资源领域授予DSSIP MTS杰出成就奖.

DSSIP and Ashghal have received two consecutive gold achievement awards from the Royal Society for the Prevention of Accidents (RoSPA). 该奖项表彰该项目在2017年和2018年期间在职业健康和安全方面的杰出表现, recognizing a strong health and safety culture across the project team, effective risk management practices and exemplary health and safety track record.

Oracle also awarded Ashghal the 公共首页行业标准化优秀奖 for use of digital engineering for process efficiency, resource utilization and record management in DSSIP.

The Doha South Sewage Infrastructure Programme is a landmark program for the region, and its impact spans far beyond the project itself. DSSIP的一个重要特点是与未来首页项目挂钩的灵活性, and when completed in full, 它将使目前位于多哈南部居民区和商业区的30多个旧泵站退役.
