(54) DEVICE FOR MANUFACTURING PACKING PILES

one

FIELD OF THE INVENTION The invention relates to the construction, in particular to the fabrication of rammed concrete piles with a high laying capacity.

A device for concreting a pile pile is known, which includes a concrete pipe, a double cone nozzle, a feed hopper and a drive 1.

The disadvantage of this device is the shallow depth of the wavy surface, which entails a slight increase in the contact of the pile with the ground.

A device for forming ramming piles is known in which a device is used including a concrete tube with screw blades and an actuator 2.

The disadvantage of this device is the low productivity of the formation of ramming piles.

The purpose of the invention is to increase the productivity and quality of the stuffed pile.

This goal is achieved by the fact that, in a device for the manufacture of printed piles, in a tubing concrete block with screw blades, an actuator, the base of the concrete block is provided, connected to it through a rotation mechanism, with a tubular head having walls in it. longitudinal movement of the sleeve interacting with the screw blades placed in the recesses of the head and hingedly attached to it, with the sleeve provided with spring-loaded retainers.

FIG. 1 shows the device until it is in contact with the bottom of the well, general view; in fig. 2 - the same, after the moment of contact with the bottom of the well; in fig. 3 is a section A-A in FIG. 2; in fig. 4 is a section BB in FIG. 2; in fig. 5 is a sectional view BB in FIG. 3; in fig. 6 — node I in FIG. five.

Claims (2)

The device for making stuffed piles includes a concrete pipe 1 with a feed funnel 2, a head 3 connected to the base of the concrete-casting pipe 1 by means of a rotation mechanism, and a sleeve 5 interacting with screw blades 6 attached to the head 3 using joints 7. The head 3 is evenly guiding screws 8 located along its circumference, on which sleeve 5 is fitted with keyed slots, equipped with clamps 9 with spring 10. In addition to the guide screws 8, head 3 is equipped with stop screws I. Device The structure has loops 12, by means of which it is suspended to a forklift 13. An armature frame 14 can be placed in a concrete-cast pipe 1. The device operates as follows. With the help of a forklift 13 and loops 12, the device is lowered into the well 15. The reinforced cage 14 is also lowered into the concrete pipe 1. the outer surface of the head 3, the spring 10 is compressed by the clips 9. Upon further lowering of the device into the borehole 15, the base of the sleeve 5 contacts the ground, as a result of which it moves relative to the head 3 along the guide screws 8. As a result of the action of the upper end of the sleeve 5 on the screw blades 6, the latter are turned around their axes on the hinges 7 and occupy an open position, and the latches 9 are in the recesses 1 of the head 3 opposite the stop screws 11 and with the help of a spring 10 acting on the latches 9, the sleeve 5 will be fixed to the head 3 and will prevent the return of the screw blades 6 to the heads. Then with the help of a forklift 13 begin lifting the device up. Due to the inclined arrangement of the blades 6, when they are pressed into the lateral surface of the well, the head 3 is rotated by means of the rotation mechanism 4, as a result of which the helical blades 6 form the helical surface of the well. As the device rises, the concrete is filled into the cavity of the well with the formed screw surface, thus ensuring the implementation of the screw-shaped rammed pile. To rotate the sleeve 5 in the lower extreme position, the stop screw 11 acts on the clips 9, compressing the spring 10. The use of a device for the fabrication of stuffed piles increases both the productivity of the work and the quality of the screw-like stuffed piles with increased bearing capacity. The invention of the device for the manufacture of stuffed piles, including a concrete pipe with screw blades, is driven in that, in order to increase the productivity and quality of the printed pile, the base of the concrete pipe is provided the walls of the pockets, with a sleeve installed in it with the possibility of longitudinal movement, interacting with screw blades placed in the niches of the head and not arnirno attached to it, m bushing is provided with spring loaded latches.
