Method of steering control of working element for hole making in quick grounds and marshy grounds

FIELD: mining.

SUBSTANCE: method of steering control of the working element for hole making in quick grounds and marshy grounds comprises immersing or rising the working element in case of deviation from the trajectory. At that the immersing or rising the working element is carried out by changing its weight. When emersion of the working element its weight is increased by supplying filler in the adjusting chamber of the working element. While immersing the working element as it moves the weight of the working element is decreased by removing a part of the filler from the said chamber of the working element.

EFFECT: immersion or emersion of the working element in the ground.

The technical solution relates to the technology of construction works and can be used for trenchless installation of underground utilities in quicksand swamp soils.

There is a method of laying a pipeline that is implemented in the RF patent №2103445, E02E 5/18, publ. 27.01.1998, including placing breakable pipe coaxially to the axis of the drill, the burst section of pipe into the ground, drilling drill head with screw located in the section of the soil, the welding of the next section of pipe, which is similar to push, and inside the ground razvarivat. However, in quicksand swamp soil pipe, placed in a specified direction, will not retain its position as the ground is saturated with water and the pipe will tend to sink into the ground, and the drilling mechanism including a screw with rasburicase head will move with the pipe. This known method of laying pipeline does not allow you to return breakable pipe trajectory. Thus, the method of laying pipeline implemented in the RF patent №2103445 not effective when piping in quicksand swamp soils, because it does not provide precision strip, which limits its use.

The closest in technical essence and essential features is the ability the b control the direction of movement of the percussion device for making holes in the ground (punch) patent of Russian Federation №2116404, E02F 5/18, E21B 7/06, publ. 27.07.1998, including the reversal of the specified device towards the right direction by application of an asymmetric cross-section of the device body strength, while on the one hand relative to the longitudinal axis of the body change the coefficient of friction of the surface area of the body that interact with the soil.

This method cannot be used in quicksand swamp soils, as well, so this method will not provide accurate movement of the working body.

The technical objective of the proposed method is to improve the accuracy of movement of the working body in a predetermined path in quicksand swamp soils by eliminating diving or surfacing of the working body in the ground.

The solution to this problem is provided by the fact that in the method of controlling the direction of movement of the working body for sinking wells in the sand and marshy grounds, including dip or rise of the working body in case of deviation from the trajectory, according to the technical solution dip or rise of the working body shall exercise the change of its mass: when the surface of the working body increase its mass by filing filler in adjusting the camera working body, and when the immersion of the working body as it advances reduce the weight of the working body p is the removal of part of the filler from the specified camera working body.

The change in mass of the working body will allow for a deviation from the trajectory to make a dip or rise of the working body, thereby to hold the working body on a given trajectory regardless of the length of the site and the degree of immersion or emersion it in quicksand or marshy ground.

It is advisable in slaboobvodnennyh the sand and swampy soils to adjust the direction of movement of the working body in the horizontal plane, which allows to increase the precision movement of the working body.

The essence of the proposed method of controlling the direction of movement of the working body for sinking wells in the sand and swampy soils is illustrated by his example of implementation shown in the drawing.

The method of controlling the direction of movement of the working body for sinking wells in the sand and swampy soils implemented as follows. Between the work 1 and the receiver 2 pits in the sand and swampy soils traces the trajectory from a given point A in the receiving pit 2. In the working pit 1 set the unit 3 control working body 4. The control unit 3 includes the need for drilling equipment, such as horizontal drilling and additional units for adjusting the direction of motion. Next, gather the working body 4, including adjusting the camera 5, SL is boobfucking rocks of the working body 4 is equipped, for example, one-way wedge for adjusting the direction of motion. Control of the shared body 4 is performed by the control unit 3 through the channel 6, for example, in the form of drill rods. You must first establish a working body 4 at a given angle α relative to the horizontal plane to reach the target point A, located in the receiving pit 2. The flow of the working body 4 is performed with the control unit 3. Progress of the working body 4 along the trajectory control of its provisions, for example, a navigation device (not shown). As rock watered when empty regulating chamber 5 working body 4 seeks to ascend (rise) in the soil, i.e. to deviate from the path. In this case, the regulating chamber 5 serves to block 3 control filler to increase the mass of the working body 4, for example water, in an amount such that the working body 4 has plunged to a predetermined trajectory (to increase the mass of the working body can also mechanical means, due to the design channel 6). When further applying the operating body 4 into the receiving pit 2, increasing its mass, for example, by increasing the length of the channel 6 it is necessary to reduce the amount of filler in the regulating chamber 5 to the value at which the working body 4 will return to zadanu the trajectory. Also, when sinking in slaboobvodnennyh the quicksand and marshy grounds worker body 4, for example, a one-sided wedge will allow, if necessary, the control unit 3 to adjust the direction of movement of the working body 4 in a horizontal plane by turning the wedge and its submission. Thus the process of controlling the direction of movement of the working body 4 for borehole according to the proposed method. After the release of the working body 4 at a given point A of the receiving pit 2 carry out its dismantling and further necessary design work.

1. The method of controlling the direction of movement of the working body for sinking wells in the sand and marshy grounds, including dip or rise of the working body in case of deviation from the trajectory, characterized in that the immersion or the rise of the working body shall exercise the change of its mass: when the surface of the working body increase its mass by filing filler in adjusting the camera working body, and when the immersion of the working body as it advances reduce the weight of the working body by removing part of the filler from the specified camera working body.

2. The method according to claim 1, characterized in that slaboobvodnennyh the sand and swampy soils correct a direction of movement of the working body in the mountains the horizontal plane.
