摘要:
Trench digging and carrying with the same bucket attachment present on one track vehicle, the created dual functionality saves both time and expense by doing on-site what would normally be required to be done with two separate vehicles and additional manpower. The bucket attachment is especially advantageous when used in areas with limited space. Another advantage is that the modification can be adapted to bucket vehicles of various sizes.

A process and tool for installing and removing various kinds of wear parts used with earth working equipment. The process and tool allows the operator to remove and install the wear parts at a safe distance so that the operator is physically remote from the potential risks of the removal and installation process. The tool may be manually operated via an operator or the tool may be a semi-automated or fully automated.

A device for supporting and guiding supplying lines used with a digging tool on a drilling machine is described. The device comprises a support branch, formed by a plurality of spacers, adjacent to one another in which a rope or tie-rod is inserted in a housing comprised in the spacers, a supplying pipe for the supplying line and a crosspiece comprising a seat adapted to support the supplying pipe. Each pair of adjacent spacers comprises retaining means. Each retaining means comprises a retaining element, associated to a first spacer of a pair of adjacent spacers, and a slot having a shape substantially matching the shape of the retaining element, associated to a second spacer of the pair of adjacent spacers. A retaining element, during use, engages with a slot allowing relative axial movement, in the longitudinal direction of the rope, of a predetermined amount.

A guidance control system is configured to control the positioning and spatial orientation of a digging implement mounted on a frame of an trenching machine for working a subsurface of earth to a desired trench profile. The position of a dynamic cutting edge of the digging implement is monitored and then controlled so that the sensed dynamic cutting edge position is equal substantially to the calculated dynamic cutting edge position. The guidance control system includes sensors, a processor, and accessible memory providing digital design information regarding the desired trench profile.

To construct an underground structure having smooth wall surfaces in a simple, safe and reliable way, plates (11,12) are buried in parallel, and soil and sand (G1) between the plates is removed. If the places where the plates are to be buried are loosened in advance, they can be buried more easily. A strut member (14) is interposed between the plates, which are used as both forms and sheathing. A hollow body, together with steel plates arranged on both sides of the hollow body, is buried into the ground, the bottom of the hollow body is closed with a shutter, the hollow body is drawn up together with soil in it, leaving the steel plates in the ground, and the remaining steel plates are used as both forms and sheathing. Reinforcement bars are disposed in the groove space thereby formed, and concrete is poured to build an underground structure.

Effective techniques and equipment are described for maintaining and improving dredge disposal sites. In one aspect, the use of winching equipment is described to move a digging vehicle within a containment area for effective creation of ditching to permit substantial dewatering and drainage of the dredge spoil to dry it. Substantially dried spoil is removed from the containment area pit using amphibious scraper equipment. The substantially dried spoil may then be used to build up the berm surrounding the dredge pit.

In a method of making holes of selective external configuration in a rock or earth formation, two or more rotatable drills provided with drill crowns are driven into the ground. The drill crowns are so arranged that they will touch each other or are radially spaced a small distance from each other and are substantially on the same level. The drill crowns are simultaneously axially displaced while they are rotated each about its own axis only. The drill crowns sit on drill rods provided with guide means such as tubes which are driven into the ground substantially simultaneously as the drill crowns. The guide means may be connected together to form a single common guide structure. When drilling two or more holes situated adjacent one or more previously drilled holes, a guide means having spacer means is inserted into a previously drilled hole, said spacer means guiding the drill for the further holes relative to the previously drilled hole by engagement with the residual walls of the drilled hole. The invention also refers to a drilling machine comprising two or more drill crowns for carrying out the above method.
摘要:
A method and apparatus for waste disposal whereby an encased helical auger may be used sequentially for creating voids in the soil and for compacting waste material in said voids; dump bin and conveyor means for feeding waste material to said encased auger and means for scattering earthen material over a considerable area of the ground after it has been removed from the earth by said auger for covering voids previously filled with waste material.
