Dewatering is the process of removing groundwater which ensures construction work can occur safely, keeps water from seeping into the site which could affect engineering, and protects the ongoing integrity of the structure and surrounding area. Groundwater is a complex and often very fragile resource which plays an important role in natural ecosystems and sub-surface hydrogeology. Also known as aquifers, groundwater sources can be accessed or interfered by different works such as basements, tanks, tunnels, trenches, and excavations. If there is groundwater on a construction site, it needs to be removed before work can begin.

Foundation Engineering Handbook pp Cite as. Whenever excavation must take place below the water table, groundwater affects the project. It affects the function and design of the facility, and the cost of its construction. Groundwater is a frequent cause of disputes between the owner and the contractor. Dewatering by unsuitable methods can under some conditions cause damage to adjacent properties, and result in third party litigation. Under some conditions dewatering may be harmful to the environment. Activities involving groundwater are closely regulated in many areas.

Dewatering is a term to describe the removal of groundwater or surface water from for example a construction site. In construction the water is pumped from wells or sumps to temporarily lower the groundwater levels, to allow excavation in dry and stable conditions below natural groundwater level. There is a variety of pumps used for it: submersible pumps , self-priming pumps, borehole pumps, etc. The presence of undesired water in a construction site can lead to safety risks , increased costs and delays to your project. Therefore, when preparing to excavate the surface or to perform dry site construction work, it is critical to use the right technique to control, manage and remove water.

Construction dewatering, unwatering, or water control are common terms used to describe removal or draining groundwater or surface water from a riverbed , construction site , caisson , or mine shaft , by pumping or evaporation. On a construction site, this dewatering may be implemented before subsurface excavation for foundations, shoring, or cellar space to lower the water table. This frequently involves the use of submersible "dewatering" pumps , centrifugal "trash" pumps, eductors, or application of vacuum to well points.

Их количество удваивалось каждую минуту. Еще немного, и любой обладатель компьютера - иностранные шпионы, радикалы, террористы - получит доступ в хранилище секретной информации американского правительства. Пока техники тщетно старались отключить электропитание, собравшиеся на подиуме пытались понять расшифрованный текст. Дэвид Беккер и два оперативных агента тоже пробовали сделать это, сидя в мини-автобусе в Севилье. ГЛАВНАЯ РАЗНИЦА МЕЖДУ ЭЛЕМЕНТАМИ, ОТВЕТСТВЕННЫМИ ЗА ХИРОСИМУ И НАГАСАКИ Соши размышляла вслух: - Элементы, ответственные за Хиросиму и Нагасаки… Пёрл-Харбор.

Я срочно уезжаю.

Это открытие было болезненным, однако правда есть правда. Стратмор скачал файл с Цифровой крепостью и запустил его в ТРАНСТЕКСТ, но программа Сквозь строй отказалась его допустить, потому что файл содержал опасную линейную мутацию. В обычных обстоятельствах это насторожило бы Стратмора, но ведь он прочитал электронную почту Танкадо, а там говорилось, что весь трюк и заключался в линейной мутации. Решив, что никакой опасности нет, Стратмор запустил файл, минуя фильтры программы Сквозь строй.

Быстрее.
