Claims (3)

1. Способ образования горизонтальных скважин в грунте, согласно которому из рабочего до приемного котлована по проектной оси трубопровода проходят пилотную скважину, затем расширяют ее до проектного диаметра трубопровода и прокладывают трубопровод в образованную скважину, отличающийся тем, что проходку пилотной скважины и уплотнение ее стенок осуществляют с помощью грунтопрокалывающего наконечника с участком в виде архимедова винта, которому сообщают вращательное и поступательное движение, при этом основную потребляемую мощность направляют на вращательное усилие, обеспечивающее окружную скорость инструмента, не превышающую 3,5 м/мин, а компенсирующее осевое усилие создают в пределах
(0-30 кг/см2)·π·R2,
где R - радиус инструмента.
1. A method of forming horizontal wells in the soil, according to which a pilot well passes from the working to the receiving foundation pit along the design axis of the pipeline, then it is expanded to the design diameter of the pipeline and the pipeline is laid into the formed well, characterized in that the pilot well is drilled and its walls are compacted using a soil-piercing tip with a section in the form of an Archimedean screw, to which rotational and translational motion is reported, while the main power consumption is direct to rotational force, providing the peripheral speed of the tool, not exceeding 3.5 m / min, and compensating axial force create within
(0-30 kg / cm 2 ) · π · R 2 ,
where R is the radius of the tool.
2. Способ по п.1, отличающийся тем, что проходку пилотной скважины, ее расширение и прокладку трубопровода осуществляют посредством удлинительных штанг, которые при посекционном наращивании и демонтаже пускают по кругу от рабочего до приемного котлована и обратно. 2. The method according to claim 1, characterized in that the sinking of the pilot well, its expansion and laying of the pipeline is carried out by means of extension rods, which, when sectioned out and dismantled, are launched in a circle from the working to the receiving pit and vice versa. 3. Способ по п.1, отличающийся тем, что при необходимости в процессе расширения скважины грунтовой керн разрезают на отдельные радиальные сегменты, разжижают и выдавливают в один из котлованов. 3. The method according to claim 1, characterized in that, if necessary, in the process of expanding the well, the soil core is cut into separate radial segments, liquefied and squeezed into one of the pits.
