Изобретение относитс к устройству ударного действи дл проходки скважин в грунте путем его уплотнени и может быть использовано дл бестраншейной прокладки подземных коммуникаций.The invention relates to a percussion device for drilling wells in the ground by compacting it and can be used for trenchless laying of underground utilities.
Известно устройство ударного действи дл проходки скважин в грунте путем его уплотнени , имеющее лизируюший наконечник и взаимодействующую с ним группу ударных механизмов, расположенных параллельно один другому в вершинах вообра- .„ жаемого треугольника. При проходке пр молинейных скважин работает одновременно вс группа ударных механизмов, сообща удары лизирующему наконечнику. Дл изменени направлени проходимой скважины осуществл етс избирательна работа s ударных механизмов таким образом, чтобы ударное воздействие на наконечник происходило на некотором плече дл создани поворотного момента 1.A percussion device is known for drilling wells in the ground by compacting it, having a lysing tip and a group of percussion mechanisms interacting with it, arranged parallel to one another at the vertices of an imaginable triangle. When drilling straight wells, the entire group of percussion mechanisms works simultaneously, together striking the lyse tip. In order to change the direction of the hole being passed, selective work of the percussion mechanisms is carried out in such a way that the impact impact on the tip takes place on a certain shoulder in order to create a turning point 1.
Однако при повороте устройства в плотных грунтах возникает большое сопротивле- 20 ние из-за того, что площадь его боковой поверхности превосходит площадь лобовой поверхности наконечника.However, when the device is rotated in dense soils, a large resistance arises due to the fact that the area of its side surface exceeds the area of the frontal surface of the tip.
При работе устройства во влажных грунтах поворот его еще более затрудн етс изза уменьшени сил сцеплени грунта с корпусом ударных механизмов и их отдаче. Скорость проходки по этой причине уменьшаетс .When operating the device in wet soils, its rotation is even more difficult due to the reduction of the forces of adhesion of the soil to the body of the percussion mechanisms and their recoil. The penetration rate for this reason decreases.
Наиболее близким техническим решение .м к предлагаемому вл етс устройство ударного действи дл проходки скважин в грунте путем его уплотнени , в котором аксиально подвижный ударник размешен в цилиндрическом заостренном корпусе с возможностью сообщени ему ударов, а снаружи вокруг корпуса закреплены удерживаюшие его при отдаче упоры, ориентированные в противоположном направлении проходки скважины и упирающиес в ее стенки.The closest technical solution to the present invention is a percussion device for drilling wells in the ground by compacting it, in which an axially movable hammer is placed in a cylindrical pointed case with the possibility of giving him blows, and stops on the outside, oriented in the opposite direction of penetration of the well and abutting against its walls.
При работе устройства обеспечиваетс повышенное сцепление корпуса с грунтом и, как следствие, повышаетс скорость проходки .When the device is operated, the body adheres to the ground and, as a result, the penetration rate increases.
В этом устройстве упоры выполнены в виде кольцевых ребер, загнутых в обратном движению устройства направлении 2.In this device, the stops are made in the form of annular ribs, bent in the direction 2 opposite to the movement of the device.
Однако при таком выполнении упоров увеличиваетс лобовое сопротивление корпусу и при работе устройства в грунтах разHowever, with such an implementation of the stops, the drag of the body increases and, when the device is used in soils,
