Привет товарищи
Роторный и шнековый способы бурения. Их отличия.
В зависимости от глубины бурения и типа почвы компания “БухтехСервис” применяет 2 способа бурения.
Роторный способ бурения. Выполняем с помощью передвижной буровой установки УРБ–2а2 на шасси ЗИЛ–131. Применяемый инструмент – шарошечные долота с широким диапазоном диаметров 75–300мм. Благодаря универсальности этого способа с легкостью разрушаются мягкие и твердые горные грунтовые слои.rotornoe-burenie
Вращательную мощность ротор направляет долотом на рабочую колонну. Для удаления разрушенной породы делают промывку через буровой насос с помощью специальных полимеров. После того, как пройдена бурением первая часть скважины, опускают первую обсадную колонну (кондуктор), чтобы перекрыть слабые неустойчивые породы и верхние водоносные горизонты, производят гидроизоляцию затрубного пространства, закачивают в него приготовленную смесь с цементом. Бурение скважины продолжается долотом меньшего диаметра внутри обсадных труб до отмеченной глубины, затем в скважину опускают следующую обсадную колонну или эксплуатационную колонну, которая будет находиться в водоносном слое.
Роторный метод обладает высокой продуктивностью и способностью обрабатывать любой тип почвы, но также и более дорогостоящий нежели шнековый.
Шнековый способ бурения популярен среди населения по причине своей простоты и доступности. Его используют в рыхлой почве и грунте средней твердости. Отличительным в технологии пробуривания шнеком является то, что отсутствует необходимость в промывке водой, так как снятие набившихся разломанных слоев почвы осуществляет шнек. Все дело в скорости обрабатывания. Но если в почве попадутся камни, использование шнека станет проблематично. Рационально использовать этот метод при строительстве скважин малой глубины в почве.
Несомненный плюс в пользу способа с применением шнека – доступная стоимость.
Технология шнекового бурения позволяет добиваться глубины бурения до 40 метров, в том числе и зимой в сильные морозы. Гораздо более глубокие скважины бурят посредством роторного способа. Он справляется с любым грунтом, в то время как шнековый способ позволяет обрабатывать только сухие и не самые твердые виды почв.
У каждого способа свои плюсы и минусы. При выборе способа бурения для своего случая нужно учитывать тип почвы в своей местности, а также климатические условия.
