Description

The invention relates to construction, namely intended for the installation of bored piles under the protection of a retrieved casing. A device is known that includes a base table with a hydraulic table, a casing pipe, a drilling tool with a drive suspended on the arrow of the base screen 1. A disadvantage of the known device is the complexity of the drive design, which is usually performed in a sealed capsule with a complicated device for supplying and moving electric cable. The closest to the proposed technical essence is a device for the construction of bored piles, including a base machine, a rod suspended from its boom with a drilling tool, a drive for its rotation, a hydraulic table, a casing connected to it. A disadvantage of the known device is the lack of possibility of well casing alignment pipe with drilling of soil in it with a rotary tool, t to to Irpplk pv nir Ya.PYa this poltak as use for this purpose under the hung grab reduces the production elnost hole penetration. The purpose of the invention is to simplify the design and increase productivity. Unitsaya, spruce is reached by those that in the device for the construction of bored piles, including a base machine, a bar with a drilling tool suspended on its boom, a drive for its rotation, a hydraulic table, a casing connected to it, a drive of the drilling tool pipe and made with a hinged base connected to it in the form of a sleeve, covering the casing. FIG. 1 shows the proposed device, a general view; in fig. 2 is a cross section A-A in FIG. one; in fig. 3 is a cross-section B-B in FIG. one; in fig. 4 - front view of,,. .. - .., “FIG 1; in fig. The 5-prong section BB in FIG. 1, in FIG. 6 is a cross section of D-D in FIG. 5. The device for constructing burrnabile piles includes a base 1, a hydraulic table 2 is attached to the undercarriage. On the boom 3 of the turntable platform of the base machine 1, the rod 4 with the swivel 5, the leash 6 with the projections 7 and the drill 8 are suspended. the hydraulic actuator 9, control console 10, bearing I, bearing 12, outriggers 13, as well as immersion and extraction hydraulic cylinders 14 and 15 reciprocating movements connected to the clamp 16 supplied with the hydraulic cylinder 17 are strengthened. Inside the table 2 there is a casing 18 At its upper end, a drive is fixed, including the base 19, a hinge support. 20, a faceplate 21 with projections 22. And a casing 23. The base 19 is connected to the grooves of the base. The washer 21 through gear 25 is connected to the engine 26. The device for the construction of bored piles works as follows. The device is first assembled. In this case, the collar 16 should tightly press the casing 18 with the help of a hydraulic strap 17, and the hydraulic table 2 should rest on the outrigger 13 and take a horizontal position. Next, the pipe 18 is immersed into the ground by its rotation at a certain angle using hydraulic cylinders 14 and simultaneously pushing the cylinders 15 connected to the clamp 16. All operations for moving the pipe 18 are carried out from the hydraulic drive 9 from the console 10 controls - the moment When the casing is rotated, it is perceived by the yoke 16, hydraulic cylinders 14, support 12, bearings 11 and further from the hydraulic table 2 through the base machine. The slope of hydrrG ho ° ta, Gob ::: eGa G; About ODT2 in the bearing I. Drilling of the soil in the pipe 18 is carried out by means of a drill tool 8 on the rod 4. When the tool 8 is immersed in the projections 7 on the leash 6, it engages with the projections 22 on the plate 21. At the same time the fixing of the rod 4 from the turn in the leash 6 is achieved by its square cross section and the corresponding hole in the leash 6. The rotation of the bur 8 is transmitted from the engine 26 through its gear 25 to the faceplate 21 and then through the lugs 22 to 7 to the leash 6 and the rod 4. Free rotation of the faceplate 21 is provided gO, but stable izatsi drive on the 18 18 - through the keys 24, which are engaged with the grooves of the base 19. To protect the drive from contamination on the faceplate 21, the housing 23 is strengthened. As the drill and drilling tool 8 moves with the rod 4 down until it is filled with soil tool cavity 8, then go to the surface and unload in turn from the well. In the case of using a pipe 18 consisting of a series of sections, when they are expanded, the actuator is removed from the pipe 18, and then installed again after the expansion. Well batching is performed when the actuator is removed from the pipe. The boom 4 from the swivel 5 is also removed, and the base machine is used for its intended purpose to perform rigging.

At the same time, the proposed device allows the drilling of wells and the construction of burr-bearing piles, both under the protective casing and without it.
