摘要： Systems and methods to provide pressed aggregate-filled cavities for improving ground stiffness and uniformity are disclosed. According to an aspect, a method includes using a mechanism to press into a ground surface in a substantially downward direction to create a concavity. The method also includes substantially or completely filling the concavity with unstabilized or chemically stabilized aggregate, soil, or sand. Further, the method includes using the mechanism to press the aggregate within the concavity to achieve a desired ground stiffness.

摘要： A device for coupling to a working end of a hydrovac boom hose is disclosed. The device includes a tubular suction tube configured for removably coupling to the working end of the hydrovac boom hose such that an opening of the working end remains unobstructed. A plurality of high pressure rotating turbo nozzles are located around a circumference of the tubular suction tube such that the rotating turbo nozzles surround the working end of the hydrovac boom hose to dislodge earthly materials under the device. The high pressure rotating turbo nozzles are configured for emitting high pressure water that dislodge earthly material. An outer housing to enclose and protect the tubular suction tube, rotating turbo nozzles, and onboard locating device, and to provide an air duct for ambient air to pass down threw. A plurality of air vents in the outer housing that provide flow of ambient air to an area being excavated. The conduit coupled with the outer housing, the conduit for allowing ingress of water to the plurality of high pressure rotating turbo nozzles.

摘要： The present invention relates to a core drill apparatus which is mounted to a working boom of an excavator so as to drill rock or a concrete structure and, more particularly, to a core drill apparatus for installation in an excavator, which comprises a ring gear and a plurality of elevation cylinders that are connected to and installed in a working support frame mounted to the end of a working boom of an excavator so as to rotate the working support frame, and at the same time, is configured to support the working frame while adjusting the height of the slope using the elevation cylinders when the working frame is supported on an inclined work surface. Therefore, the present invention enables a drilling bit provided in the working support frame to stably drill a structure regardless of the inclination of a work surface to be drilled, and can thus significantly improve the efficiency of a drilling operation.

摘要： An underground-structure construction method of arranging an underground structure by causing drilling apparatuses engaged with a concrete-made closed-shaped bottom frame to travel in a reciprocating manner to drill a just-underground of a bottom part of the underground structure, discharging to an earth surface excavated earth and sand of an internal ground, and extending a building frame of an upper part of the underground structure includes: open-cutting a ground to form a larger-sized mortar-shaped working hole; forming a closed-shaped horizontal reference area in an edge ground; arranging a bottom frame on the horizontal reference area; building a first stage building frame on the bottom frame; and backfilling, with backfill soil, an annular-shaped outer space of inner and outer spaces as a result of dividing the working hole, the drilling apparatuses being caused to uniformly drill, from the horizontal reference area as a drilling initiation plane, the just-underground of the bottom part.

摘要： A machine and method utilize a tracked undercarriage including a frame with a central body, front and rear transverse assemblies connected to the central body and extending on opposite sides. Each of a pair of lateral tracks is connected, at the front and at the rear, to ends of the transverse assemblies. The base machine includes excavation equipment having different working positions/configurations. Each of a pair of front load cells of the tracked undercarriage is mounted between a lateral track and the front transverse assembly. Each of a pair of rear load cells is mounted between a lateral track and the rear transverse assembly. Each load detects force data indicating the reaction force exerted between the associated lateral track and the respective transverse assembly. A control system computes a barycentre planar position of the machine situated substantially at a reference plane computed as a function of the force data.
