Indentation device for piles

The utility model relates to the field of construction, in particular to devices for pressing piles, dowels, casing pipes, cores, shells, etc. elements.

The ABC-35 installation is known for pushing piles under the supports of power lines and a contact network, mounted on two tractors, one of which is a working one and a second one. 1 A pressing equipment is installed on the working tractor. The reinforced concrete pile is pressed into the ground using a winch, the force of which is transmitted through the chain hoist system and a movable headgear.

The disadvantages of the installation are:

bulkiness of equipment, in connection with which it is difficult to use installations in cramped construction conditions;

small pushing force, which limits the size of the piles.

the inability to immerse piles close to one another and protruding above the soil surface by more than 0.6 m, as well as to produce pile bushes.

The closest technical solution to the utility model is a device for immersion piles indentation, which contains a basic machine with attachments, a guide rack with a working body and a special anchor. 2

However, the known equipment does not provide full use of the length of the guide strut, has a relatively small performance due to the idle strokes of the power cylinder rod and low reliability, due to the presence of an additional locking device and the large length of flexible hydraulic hoses forced to move with a cylindrical hydraulic cylinder., H , The objective of the utility model is to increase the productivity and reliability of the device for immersing piles by indentation due to liquids; | and cyclic process of pile sinking and simplification of the design.

The specified technical result is achieved by the fact that the working body of the device for immersion piles by indentation is made in the form of a hydraulic cylinder with a flexible rod to the middle of which a pile head cap is attached that moves along the guide rack, and the rod itself is looped through bypass blocks around the guide rack (pile mast)

In FIG. 1 shows a device for immersion piles indentation on the basis of the tractor, side view; in FIG. 2 scheme of the working body; in FIG. 3 is a section along AA in FIG. 2. (Vice-rector for scientific work: pile machines with a lateral arrangement of a guide rack (pile mast), for example, SP-49, S-878, KO-16. Therefore, in the application, as a base machine, Fig. 1 shows a copier equipment with a lateral arrangement of a guide device (pile mast). The device for immersion piles by indentation (Fig. 1) contains a base machine 1 with attachments guiding the rack 2, to the rear of which is attached a working member 3, made in the form of a hydraulic cylinder with a flexible rod 4, to the middle of which ( Fig. 2a) attached n pile headgear 5, moving along the guide post 2 in the front part .. The working body rod 4 is looped through the bypass blocks 6 located at the upper and lower ends of the guide post 2. The reactive force arising from the pressing of the pile 7 is received by the guide post 2 and transmitted to a special anchor device 8, through the console 9. The device for immersion piles works as follows: After installing the base machine 1 on the dive point of the pile, install a vertical guide rack 2 and produce anch alignment with anchor 8. When supplying the working fluid to the under-piston cavity of the hydraulic cylinder 3, the pile head 5 is lowered into the lower position, the pile 7 is pulled and put into the head 5. When the working fluid is fed into the over-piston cavity of the hydraulic cylinder, the head 5 with the pile 7 is raised and the pile 7 is installed to the starting position. Then the liquid is again fed into the sub-piston cavity of the working body. The head restraint 5, lowering, transfers the force developed by the hydraulic cylinder 3 to the pile 7 and presses it into the ground. The soil reactivity when immersing piles 7 is perceived by the weight of the base machine 1 and the anchor device 8. The process of immersing piles is carried out continuously. The indentation rate depends on the flow rate of the working fluid. After immersion of the pile 7 in the ground, the anchor 8 is removed, the base machine 1 is moved to the place of immersion of the next pile. The implementation of the working body in the form of a hydraulic cylinder with a flexible rod 4, to the middle of which is attached a pile head cap 5, which moves along the guide post 2, and the rod itself is looped through bypass blocks 6 around the guide post 2, eliminates the cyclical nature of the device and simplify the design, which generally leads to increased performance and reliability of the device for pushing piles. 1.Ganichev I.A.
