DRAINING EQUIPMENT DESTINED TO LAND RECLAMATION WORKS

摘要

The invention relates to a changeable equipment that can be mounted on a bulldozer and used in closed, trenchless drainage works. The draining equipment consists of a chassis on which is articulated the frame of the scorification equipment, at its lower part, through an axle bearing, being articulated a vertical knife which allows the introduction of the drain tube; in the ground, the knife is maintained in working position with two hydraulic cylinders, which are part of the equipment and are mounted on the same frame; in order to remove compaction and allow good soil break up, they have a knife provided with a lower tip used for the equipment teeth; on the knife slanted edge is screwed a plate wider than the knife's thickness; for soil break-up, it is provided in the knife's lower part with some nozzles, mounted on a tube through which are sprayed chemical substances for soil stabilization; for digging angle control and correction, it is provided with a device consisting of a tube made of electro-insulating material, curved upward and partially filled with mercury, which moves according to the element working position, establishing thus the electrical connection between the contacts mounted in the tube.
