Abstract
Способ горизонтального дренажа подтопленных сооружений на свайных основаниях, включающий проходку шахтного ствола с внешней стороны объекта и бурение лучевых скважин параллельно внешним стенам защищаемого объекта, отличающийся тем, что из лучевой скважины, расположенной нормально рядам несущих свай, используя забойный двигатель и отклонители направления бурения проходят дополнительные боковые дренажные скважины, направленные под ростверк сооружения между рядами свай, дополнительные боковые дренажные скважины выводят за внешние границы объекта не менее чем на 5 м; при бурении с помощью забойного двигателя в дополнительные боковые дренажные скважины протягивают фильтровые колонны из гибких фильтров, устойчивость стенок лучевых и дополнительных боковых дренажных скважин достигается за счет применения гипановых или других самораспадающихся буровых растворов, после завершения проходки дополнительных боковых дренажных скважин, отсоединенный буровой инструмент используют для перекрытия забоя дополнительной боковой дренажной скважины и оставляют в грунтовом массиве, а забойный двигатель вместе с бурильными трубами извлекают через фильтровую колонну, главным отличительным признаком предлагаемого способа защиты объектов от подтопления.A method of horizontal drainage of flooded structures on pile foundations, including sinking a shaft shaft from the outside of an object and drilling beam wells parallel to the external walls of the protected object, characterized in that from the beam well located normally to the rows of bearing piles using an downhole motor and directional drills go through additional lateral drainage wells directed under the grill of the structure between the rows of piles, additional lateral drainage wells lead outside the ANRITSU object is not less than 5 m; when drilling using a downhole motor, filter columns from flexible filters are pulled into additional lateral drainage wells, the stability of the walls of the beam and additional lateral drainage wells is achieved through the use of gypsum or other self-dissolving drilling fluids, after completing the drilling of additional lateral drainage wells, the disconnected drilling tool is used to overlapping the bottom of the additional lateral drainage well and leave it in the soil mass, and the downhole motor together with drill pipes removed through the filter string, the main distinguishing feature of the proposed method of protecting objects from flooding.
