Изобретение относитс к устройствам дл бестраншейной прокладки трубопроводов под дорогами, а точнее к разработке горизонтальных скважин пробойниками ударного действи (тшевматическими, гидравлическими или электрическими ) .The invention relates to devices for trenchless laying of pipelines under roads, and more specifically to the development of horizontal wells with percussion punch pins (tshevmaticheskimi, hydraulic or electric).
Известно устройство дл образовани скважин в грунте, выполненное в виде пневмопробойника . Такое устройство надежно и удобно в работе 1 .A device for the formation of wells in the ground, made in the form of pneumatic punch. Such a device is reliable and convenient in operation 1.
Однако оно обладает малой энергией удара , достаточной дл прокладки скважин только малого диаметра (90-130 мм). Дл проходки скважин большего диаметра примен ют вторичную ее проходку тем же пневмопробойником , но оснащенным расширителем.However, it has low impact energy, sufficient for laying wells of only small diameter (90-130 mm). For the drilling of wells of larger diameter, its secondary penetration is used by the same pneumatic punch, but equipped with an expander.
Наиболее близким к изобретению вл етс устройство дл образовани скважин в грзште, включающее пневмопробойник с концентрично расположенным расщирителем, монтированным на пробойнике посредством втулки и ребер 2.Closest to the invention is a device for the formation of wells in a grinder, including a pneumatic punch with a concentrically located dilator mounted on a punch by means of a sleeve and ribs 2.
Известное устройство характеризуетс повышенным сопротивлетшем процессу проходки за счет увеличенного лобового сечени , что резко снижает скорость проходки и приводит к нерациональному использованию ограниченного моторесурса пневмопробойника.The known device is characterized by an increased resistance to the penetration process due to an increased frontal section, which drastically reduces the penetration rate and leads to the irrational use of the limited pneumopunch motor life.
Целью изобретени вл етс увеличение скорости проходки расширенной скважины за счет снижени грунтового сопротивлени .The aim of the invention is to increase the rate of penetration of the expanded well by reducing the ground resistance.
Указанна цель достигаетс тем, что в устройстве расширитель вьтолнен в виде тру- бы, к обеим концам которой пршс1 еплены This goal is achieved by the fact that, in the device, the expander is fulfilled in the form of a pipe, to both ends of which is provided
10 элементы скреплени с канатами. Причем один из канатов может бьтгь прикреплен к лидирующему наконечнику, который монтирован на конической втулке, при этом диаметр наконечника равен диаметру пробойника.10 elements of fastening with ropes. Moreover, one of the ropes may be attached to the lead tip, which is mounted on a conical sleeve, and the tip diameter is equal to the diameter of the piercer.

Ребра 2 и 5 расположены так, что их проекции на20, parts of the pipe 1 there are also ribs 5 connected to a cylindrical sleeve 6 supporting the body of the piercer 4. The ribs 2 and 5 are arranged so that their projections onto
