Description

Известно устройство дл образовани горизонтальной выработки методом прокола, включающее корпус, гидропрессы, паунсон со штоком и распорный механизм.A device for the formation of horizontal generation by the puncture method is known, which includes a housing, hydraulic presses, paunson with a stem and a spacer mechanism.

В предлагаемом устройстве дл образовани горизонтальной выработки методом прокола с целью обеспечени образовани тоннелей в плотных и прочных грунтах шток пуансона вьшолнен по длине составным с секци ми, причем гидропрессы установлены в корпусе устройства последовательно , а пуансон вьшолнен в виде конуса с выступом.In the proposed device for the formation of horizontal excavation by the method of puncture to ensure the formation of tunnels in dense and durable soils, the punch rod is extended along the length of the composite sections, the hydraulic presses are installed in the device body sequentially, and the punch is executed in the form of a cone with a protrusion.

На чертеже изображено предложенное устройство .The drawing shows the proposed device.

В корпусе 1 последовательно установлены гидропрессы 2, пуансон 3 со пп:оком 4, вьшолненным по длине составным с секци ми 5.Hydropresses 2 are sequentially installed in the housing 1, the punch 3 with the PP: eye 4, the composite with sections 5, which has been completed along the length.

Штоки гидропрессов 6 соединены через стойки 7 с корпусом 1, торец хвостовой части которого св зан с распорным механизмом В, имеющим две полуцилиндрические оболочки 9, раздвигаемые клинь ми.The rods of the hydraulic presses 6 are connected through racks 7 to the housing 1, the end of the tail part of which is connected with the spacer mechanism B, which has two semi-cylindrical shells 9, which are wedged apart.

Подача рабочей жидкости в гидропрессы 2 осуществл етс насосами 10 с электроприводами 11, подвод злектроэнергии к которым осуществл етс при помощи магистрального высоковольтного кабел 12. Кабель 12 следует пропускать в выработку через пробзфенные скважины.The working fluid is supplied to hydraulic presses 2 by pumps 10 with electric drives 11, which are supplied with electric power by means of a high-voltage high-voltage cable 12. Cable 12 should be passed into production through sampling wells.

Насосы устанавливаютс в хвостовой части 13 устройства. В систему гидравлической схемы вход т распределительньп золотниковьш механизм 14, предназначаемый дл распределени подачи жидкости из насосов 10 в гидропрессы 2, бак 15 и силовые гидроцилиндры 16 и 17, предназначаемые дл привода конической шайбы 18, устройства управлени изменением направлени прокола горизонтальной выработки.Pumps are installed in the tail section 13 of the device. The hydraulic circuit includes a distributor spool mechanism 14, designed to distribute the flow of fluid from pumps 10 to hydraulic presses 2, tank 15 and power cylinders 16 and 17, designed to drive a conical washer 18, a control device for changing the direction of a horizontal hole.

Дл создани в процессе прокола проходного канала, предназначаемого дл осуществлени доступа через специальные люки ко всем механизмам устройства, пуансон 3 вьшолнен в виде конуса с выступом 19.In order to create in the process of puncture a passageway intended for accessing through special hatches to all mechanisms of the device, the punch 3 is made in the form of a cone with a protrusion 19.

Дл прокола участков вьфаботки в неплотных и непрочных грунтах дл уплотнени ее стенок в пуансоне 3 предусмотрено вибрационно-ударное устройство 20.In order to puncture the sections of the piercing in loose and fragile soils, a vibration-impact device 20 is provided for sealing its walls in the punch 3.

Claims

The proposed device operates automatically in a closed working cycle: pressing into the bottom of the Luanson 3 and retracting the housing 1 with the spacer mechanism 8 and the tail part 13 to the initial position to produce the next pressure. The cycle of pressing the punch 3 into the face is performed as follows. Using pumps 10 working fluid under high pressure (about several hundred atmospheres), the spool mechanism 14 passes, enters the working cavity of hydraulic presses 2, under the effect of the total force of which the body 1, moving back, jams the expansion mechanism 8 into the walls of the working, and the punch 3 is pressed into the face for the stroke length of the rod 4. The cycle of pushing the body 1 with the tail part to the initial position for the production of the subsequent indentation proceeds as follows. During the production cycle of the indentation of the punch 3 into the downhole-spool mechanism 14 automatically connects the working cavity of hydraulic presses 2 to the tank 15 for draining the fluid and simultaneously connects the delivery line of pumps 10 to the opposite cavity of hydraulic presses 2. Under the action of the total force of the hydraulic presses 2, the body 1 advances wedges the expansion mechanism B and tightens the entire tail section of the device to a new initial position. The cycle is repeated. The indentation cycle of the punch 3 in the face when piercing production areas in loose and non-ground soils is performed with vibrating-shock state 20 operating. At the same time, in order to ensure jamming of the punch 3 in the walls, at the end of each pin, when the vibration-shock device 20 is turned off. To ensure the straightness of the puncture tunnel, the projection of the cone of the punch 3 is slightly shifted downwards so that the areas along The cross section of the punch, located above and below the horizontal axis passing through the protrusion of the cone of the punch, were equal in size. Controlling the change in direction of the puncture is performed by radial displacements of the conical washer 18 by means of power cylinders 16 and 17, which are perpendicular to each other. Claim 1. A device for the formation of horizontal production by a puncture method, including a housing, hydraulic presses, a punch with a rod, a spreading mechanism, characterized in that, in order to form tunnels in strong and dense soils, the punch bars are extruded along the length of the composite with sections, and hydraulic presses are installed in the device in series.

2. The device according to claim 1, of which there is a cone with a cone with a protrusion.
