Description

(54) PILED

The invention relates to industrial and civil construction and can be used in the construction of bridges, television masts, gantry cranes and other structures in which piles operate with alternating loads (for lifting and indentation).

In a well-known retractable blade pile with a chain of psysheui of its layers, the ability of the loiasty is revealed by mechanical action through the pile cavity on the mechanism to open the blades 1 j.

. /

The disadvantage of such a pile is that the area of the blades is limited by the size of the body and, thereby, the increase in its carrying capacity is limited.

The closest to the present invention in its technical nature is the pile, comprising a hollow shaft with a blade that opens, 2l.

; The disadvantage of this pile is that the area of the retractable blades is limited by the size of the body of the pile, and thus the bearing capacity of the pile as a whole.

The purpose of the invention is to increase the bearing capacity of the pile.

This is achieved by the fact that the shaft is equipped with shafts, on each of which a blade is installed, the axis of each shaft is located below the center of gravity of the looaoti, and in place of the blade next to the shaft there is a fitment of the right side.

On fgg. 1 depicts a pile at the time of submersion into the ground (total VVD) in FIG. 2 - lower part of the pile with a partial incision; in fig. 3 - Sechevve And “And fvg. 2} in FIG. 4 - Sichiv BB FIG. 2} on fng. 5 bottom part of the pile in the building of ntxiaoite; va figs, 6 - vba b figs, s.

The SVA includes the POLE 1 trunk, on the end of which there are openings 2, of which the hinge E is pivotally attached with the possibility of rotation around its horizontal axis 4,

Claims (2)

The blades 3 consist of plates 5 with one longitudinal channel 6 and several marginal channels 7. All transverse channels 7 are connected to the longitudinal channels 6 E and are connected to the inside of the blade 8 with the outer surface of the blade 3, the Blade 3 is mated with the shaft by means of the shaft 9 At the end of the shaft 9, a ring-shaped image is welded onto the washer 10, On the washer 10 there are two sockets 11, inside of which are recessed under spring fingers 12, At the end of the swath 1 are attached onqpfaj 13, on which I have two holes 14. Holes 14 and sockets 11 are located at an angle of 9o to each other. At the end of shaft 9, there are square protrusions 15, which are included in the notches 16 of the retainer 17, which are manganese on the hydraulical shock force, “le 18.” In the lower part of the pile, on the drill pipes 19, a hydraulic strike was ejected by the mechanism 18, which is installed 10. Drill bits 19 aartneug 20 are connected to a water pump 21 by means of a flexible hose 22. The SV is loaded into the ground as follows. Before the pile is immersed in the ground, lopaTB 3 is installed in the vertical fall. Generator is fixed in it with a fixer ITs laid out on the hydraulic mechanism 18, Pump 21 supplies water under pressure “Yuraa Flexible hose 22, swivel 2O and bu“ pipes 19 to the hydraulic mechanism Namu 18, Supply of water under pressure to the impact mechanism 18 provides soada air vibrations in the vertical direction. From now on, the water flows through the aeroolve {6 and piparechnye 7 channels to the outer air and erodes the shaft outside the trench through which the mouth passes 3. As a result, the soil resistance decreases as soon as the pile is immersed in the soil by its own. After loading the piles into the ground to the design mark, the hydraulic hammer mechanism 18 is removed with the lock 17 with the IMAZ-7 lock 17 and the chDEa are lowered by the hydraulic mechanism 18 (without lock 17) from the bottom of the pile. Then the Aragca shaft 1 is started using the screwing mechanism. Due to the fact that the axes of the shafts on which the blades 3 are located lie at the bottom of the center of the sheet of nonac-refij, the latter start to rotate around the axes of the shafts. , vraszut until the blades are fixed-ruyugs in a horizontal position. This is achieved by the fact that the slots 11 on the washer 10 and the o-wool 14 on the supports 13 coincide and 1 draws into the trunk 14, so that the blades 3 are automatically fixed in a horizontal position relative to the body of the pile. The application of the proposed szhi facilitates the process of opening the lopagegea and will exclude the construction of foundations from the bottom of the mine, and also replaces the pile driving equipment with a light baud. Cava's claims, comprising a hollow stem with a blade blade MI; It is equipped with shafts, in order to increase the carrying capacity of the pile, it is equipped with shafts, on each of which you can freely set the axis other than the center. Zhega blades, and in the place of junction of each blade to the trunk there is a ustansfpeno fixing device. Sources of information taken into account during the examination: 1.
