Изобретение относитс к строитель ной технике, в частности к буровым установкам дл сооружени дренаиных скважин в грунтеThe invention relates to construction equipment, in particular to drilling rigs for the construction of drainage wells in the ground.

Известно устройство дл образоадни дренажных скважин в грунте, включающее реверсивный привод/ установленный на станине и соединенный с рабочим органом в виде шнека, помещенного в трубу круглого сечени A device for the formation of drainage wells in the ground is known, which includes a reversing drive / mounted on a bed and connected to a working body in the form of a screw placed in a circular pipe.

1.one.

Недостатком такого устройства вл етс невозможность сооружени дренажных скважин, которые имели бы большую дренирующую поверхность, чем кругла .Наиболее близким по технической сущности и достигаемому результату к изобретению вп етс бурошнекова машина, включаквда опоры, соединенные со штангами, на которых установлена станина с приводом, св занным посредством реверсивного редуктора с рабочим органом, выполненным .в виде спаренных шнеков, и 6yHKep 2j.The disadvantage of such a device is the impossibility of constructing drainage wells that would have a greater drainage surface than a round one. The most close to the technical essence and the achieved result of the invention is a brown-screw machine, including supports, connected to the rods on which the frame with the drive is mounted connected by means of a reverse gearbox with a working body, made in the form of twin augers, and 6yHKep 2j.

Недостатком этого устройства вл етс ненадежности- образовани дренажных скйажин в грунте, поскольку в процессе их закладки дренирующим материалом -при обратном вращенииThe disadvantage of this device is the unreliability of the formation of drainage skips in the ground, because in the process of their laying the drainage material - during the reverse rotation

шнеков возможны обвалы стенок скважины , что приводит к снижению ее дренирующего эффекта.augers possible collapses of the borehole walls, which leads to a decrease in its drainage effect.

Целью изобретени вл етс повышение надежности сооружени дренгикных скважин.The aim of the invention is to improve the reliability of the construction of the dengue wells.

Поставленна цель достигаетс тем, что рабочий орган машины помещен в трубу, соединенную с бункером The goal is achieved by the fact that the working body of the machine is placed in a pipe connected to the bunker

10 и и леющую в передней части сечение эллипсоидной формы, а на хвостовой части - круглое сечение, при этом один из шнековразмещен по всей длине трубы, а . второй только в перед15 ней ее ;части, причем шаг витков шнека расположенного в хвостовой части трубы, больше шага витков шнеков размещенных в передней части трубы.10 and a section in the front part is an ellipsoidal shape, and on the tail part there is a circular section, one of the screws being located along the entire length of the pipe, a. the second is only in front of it; parts, and the pitch of the turns of the screw located in the tail section of the pipe is greater than the pitch of the turns of the screws located at the front of the pipe.

Бурошнекова ма1Ш1на содержит раму , состо щую из.двух продолы : штанг 1, из двух поперечин, одна Buroshnekova ma1Sh1na contains a frame consisting of two longitudinal: rod 1, of two crossbars, one

25 из которых 2 вл етс осью ходовых колес.3, а втора 4 служит дл увеличени жесткости конструкции, Штанги 1 с помощью захватов 5 прикреплены к onopeiM 6, которые шарнирно соединены с телескопическими опорами25 of which 2 is the axis of the traveling wheels. 3, and the second 4 serves to increase the rigidity of the structure. The rods 1 are attached with grips 5 to the onopeiM 6, which are hinged to the telescopic supports

Claims

30 7. On the rods 1 a frame 8 is installed, having an engine 9 with reversible gear 10. A pipe 11 with a bunker 12 is attached to the bed, having an ellipsoidal width 13 in the front part, a screw 14 is placed in the pipe 11 and the hopper 12, 13 has a pitch two times smaller than in the circular section of the pipe 11. In the widened section 4 and 13 under the screw 14 is placed the screw 15 with the shaft 16 passing under the pipe 11 and connected to the drive 15. The pitch of the screw 15 is similar to the pitch of the screw 14, located in the wider part 13. The front ends of the screws 14 and 15 are equipped with drilling akonechnikami 17 and 18. In the pipe under the hopper has a window 19 which is provided with a valve 20. At the bottom side of the gear housing 10 there are gears 21, which come into engagement with the holes formed along the surface vnut renney rods 1. The apparatus operates as follows. With the help of the rods 1 and the stops 7, the device is installed in the working position (Fig. 1, the rods are fixed by the grippers 5). Then the engine 9 is turned on, and the gearbox 10 transmits the rotation to the working member consisting of two screws 14 and 15. When the working organ on the ground is destroyed by the tips 17 and 18 and, moving along the broadened part 13 of the pipe 11, enters the hopper 12 and pours out through the window 19 with the open valve 20. Thus, the well with the cross section of the ellipsoid is drilled. wells The valve 20 is opened, the drainage material is fed into the bunker 12, the reverse rotation of the engine 9 is turned on, and the screws 14 and 15 begin to rotate in the opposite direction, feeding the drainage material to the bottom of the hole, while the stand 8 is moved backwards. The ingress of foreign material into the well is excluded, which makes the construction of a drainage well more reliable. The invention of the Buroshnekov machine includes a support connected to rods on which a bed with vodom, bound by reversing gear with a working body designed as a twin-screw, and a hopper, wherein. That, in order to improve the reliability of the construction of drainage wells, the working body is placed in a pipe connected to the bunker and having an ellipsoidal cross section in the front part, and a circular cross section on the tail part, one of the screws being placed along the entire length of the pipe. its front part, and the pitch of the turns of the screw located in the tail part of the pipe, is greater than the pitch of the turns of the screws placed in front of the pipe.
