FIELD: civil engineering. SUBSTANCE: method includes installation of anchor 30, placing drilling rig on platform 1 with vertically installed working member 6, providing kinematic link between platform 1 and anchor 30, forming a cavity in the form of slot using drilling rig 6 along 259 route of wall 260 with platform 1 rotation about anchor 30 and filling cavity with wall material. The specific feature of the anchor is drilling rig 5 moved forward in parallel to the mutually perpendicular OC, to vertical geometric axes O and C, physical rotation axle 35 and working member 6, concurrently or not concurrently with platform 1 rotation depending on structure layout and used continuous or cyclic principle for ground distortion. Ungirding of the method is possible including installation of several anchors including on both sides of the wall route, for instance, in two lines, and platform rotation is carried out using the anchor alternately from each line. Internal cylindrical surface of the front shaft of shaft well may be used as anchor, and template installed along its route, including concrete collar, may be used for automatic treating non-circular wall. Ground inside wall contour of the shaft well may be driven by layers (circular or non-circular) about internal or external anchors. Platform 1 used to implement the method includes frame 2 with three supports - two ones 15 and 16 are provided with running wheels 19, and one in the form of anchor 30 related to frame 2 through vertical rotary axle 35, rotation mechanism 3 and fastening member 47 of the drilling mean 5. Platform 1 is provided with carriage 4 of drilling rig 5. Window 46 for working member 6 is provided in carriage 4. Lengthwise aperture 39 is provided in frame 2. Frame 2 is supplied with two hydraulic cylinders 8 for moving carriage 4 and its guides 14 placed in parallel to aperture 39 and perpendicularly to rotation axle 35. Running wheels 19 rest on track 71 of flat members with circular route 261. Platform options are possible: running wheels are installed in supports so as to be moved in vertical direction and stopped; rotation axle and frame may be moved with two degrees of freedom; two additional supports with running wheels, additional axle of rotation and mechanism of rotation; following member for relating to drilling rig carriage to the template; mechanism of rotation, excluding hoist, of pushing reversing and not reversing types; rotation axle in the form of not less than three centering rollers; installation of the three centering rollers and running wheels supports so as to be moved in horizontal direction and stopping; additional; supports for running wheels placed on rotation axle carriage or on separate carriage; rotary drilling rig carriage with stopping through any 180 degrees. EFFECT: moving running wheels of the platform over circular trajectory. 27 cl, 47 dwg |
