Привет товарищи
Артезианская и песчаная виды скважин.
Ориентируясь на цели и нужды своего заказчика компания “БурТехСервис” выполняет бурение как скважин на песок (до первого водоносного слоя – песчаный слой), так и артезианских скважин, расположенных глубже (водоносный слой известняк, в котором естественными способами отфильтровывается вода).

Давайте разберемся, какому типу скважин отдать предпочтение.

Сравнение артезианского и песчаного типов скважин
Критерий

Скважина на песок

Артезианская скважина

Глубина

Бурение осуществляется на небольшую глубину до первого водоносного (песчаного) слоя – 20-60 метров

При бурении артезианской скважины можно достичь большой глубины (до 250 метров)

Срок службы

10-20 лет при условии регулярной эксплуатации

Срок службы составляет свыше 50 лет независимо от регулярности эксплуатации

Дебит (производительность) скважины

Небольшой – около 600 литров в час

Большой дебит скважины (до 20 м3 в час)

Особенности монтажа

Сложности при монтаже и эксплуатации оборудования для подачи воды.

Не возникает трудностей при монтаже и использовании оборудования.

Фильтр

Необходимо установить фильтр для защиты питьевой воды от попадания в нее песка и других загрязнений

Необходимости в установке фильтров нет, поскольку вода в известняковом слое отфильтровывается и обеззараживается естественными способами

Затраты

Скважины на песок – популярный и незатратный способ провести воду в дом

Затраты гораздо выше ввиду сложностей проведения буровых работ и монтажа оборудования

Объём водоснабжения

Воды хватает на покрытие нужд лишь одного дома

Водоснабжения с лихвой хватает на весь частный сектор или посёлок.

Артезианская скважина
Скважина на песок
Популярность этого типа скважин обусловлена доступной ценой и быстротой построения. Весь процесс состоит из следующих этапов:

Бурение скважины роторным или шнековым способом.
В пробуренное отверстие монтируем обсадную трубу. В качестве обсадных труб используем трубы нПВХ из пищевого пластика ?90 или ?125. Они наиболее эффективно обеспечивают целостность ствола скважины и защищают оборудование от различных механических нагрузок извне
После этого устанавливаем 3-метровый фильтр из полиамидной сетки галунного плетения европейского производства. Он защищает воду от попадания в нее песка и других загрязнений.
Обсыпка фильтра фильтрующим песком
Прокачка скважины до визуально чистой воды.
Подбор и установка насосного оборудования.
После того как скважина пробурена и установлен насос для обеспечения подъема воды на поверхность, рекомендуется обустроить скважину необходимым оборудованием. Обустройство скважины продляет срок ее эксплуатации, сохраняя ее в работоспособном состоянии долгие годы. С вариантами обустройства вы можете ознакомиться здесь.

Артезианская скважина (на известняк)
В артезианской скважине водоносный слой находится между двумя слоями известняковой породы на достаточно большой глубине – до 250 метров. Это обеспечивает воде непревзойденное качество и чистоту. Установка фильтров не требуется – на такой глубине вода отфильтровывается естественными способами.

Скважина артезианского типа бурится роторном способом. Существует 4 вида конструкции артезианской скважины;

Стандартная. В этом случае в грунтовом слое не содержится песка и глины, а давление воды очень высокое. Скважину оснащают одной металлической обсадной трубой. Диаметр трубы может достигать 159 мм. Не требует глубокого погружения насоса — воду можно добывать уже при наполненности 2 труб — до этой отметки она поднимается спокойно.
С двойной обсадной трубой. В грунтовом слое имеется и песок, и глина, а давление воды очень слабое – самый оптимальный вариант для проведения работ. Без глинистых слоев встречаются довольно редко, потому чаще монтируется скважина с двойной обсадной трубой. Дополнительный элемент монтируется в зоне с сухим известняком.
С кондуктором. В грунтовом слое не имеется песка и глины, давление воды высокое, но могут существовать преграды в верхних слоях – плывуны. Именно там монтируется кондуктор. Это помогает компенсировать давление.
Телескопическая конструкция. Применяется в местах с неустойчивым грунтом с камнями и валунами. Конструкцию называют телескопической, так как здесь используется сразу три обсадных металлических трубы. Это позволяет компенсировать сильное давление среды.
В распоряжении “БурТехСервис” имеется полной набор специальной техники, необходимой для проведения буровых работ на всех этапах, включая земельные работы. Вы можете ознакомиться со буровыми комплектами , а также с фотографиями техники в процессе работы.

Свяжитесь с нами по телефону или оставьте заявку,наш специалист проконсультирует вас по всем вопросам бурения, а также обустройства скважин. В компании “БурТехСервис” работают высококвалифицированные и опытные специалисты по бурению — после окончания работ у вас будет сооружена автономная скважина с чистой водой.
