Description

1

The invention relates to the construction and can be used for the construction of the foundation.

The aim of the invention is to reduce energy consumption by immersing or extracting split-length elements on the section.

Fig. 1 shows a device for immersing or extracting hollow elements, a general view; in fig. 2 is a sectional view in FIG. 1j of FIG. 3 is a section BB in FIG. 1 in FIG. 4 - section bb In Fig „1„

The device for immersing or extracting the hollow elements consists of one-type horizontal unbalance shafts 2 and 3S connected to the reversible drive 1 which are fixed to sections 4 and 5 of the hollow element that is cut along the length. Between themselves, the action and 5 are connected by means of an elastic tape 6. The unbalance shafts 2 and 3 are fixed on sections 4 and 5 parallel to the reserve plane and connected to each other through synchronizers made in the form of splined shafts 7, to intensify the immersion or extraction processes x 4 and 5 can be installed on several groups of unbalance shafts 2 and 3. At each section, the unbalance shafts are interconnected by means of gears 8.

The operation of the device is as follows.

To immerse the building element, a small well is preliminarily formed, the device is inserted into it and drive 1 is turned on, and the direction of rotation of the drive is chosen so that the unbalances of shafts 2 and 3 rise upwards after the divergence. In this case, after the unbalance of shafts 2 and 3

will begin to disperse, they will sweep sections 4 and 5 behind them, as a result of which the latter will tightly press against the walls of the well. Then the unbalances of the shafts 2 and 3 will begin to move upwards, and sections 4 and 5 due to the friction between them and the walls of the well will remain in place. Upon further rotation, the unbalances of shafts 2 and 3 together with sections 4 and 5 will converge, which will lead to the formation of a gap between sections 4 and 5 and the walls of the well and the possibility of intensive immersion of sections 4 and 5 in

5 soil when moving debalans shaft 2 and 3 down. After which the cycle is repeated.

To remove the building element, the direction of rotation of the actuator 1 is changed, with the result that after the unbalance of the shafts 2 and 3 are dispersed, they will move downwards, which will cause the building element to lock. And after

The 5 unbalances of the shafts 2 and 3 will descend, together with sections 4 and 5, they are directed upwards, which will lead to the extraction of the building element.
