Abstract:
The invention contemplates a working implement, for use with an excavating type machine, which semi-automatically brings a pipe section to a specified grade, slope, and line for emplacement in a line of pipe sections to be laid on the specified grade slope and line. The implement is rigidly mounted to the excavation machine whereby the position of the implement can be maintained within narrow tolerances while the pipe section is linearly inserted into a previously laid pipe section, and can be retained at the specified grade, slope, and line while fill material is emplaced and consolidated about and under the pipe, with sufficient density that the pipe can be released without the pipe moving outside normal tolerances of the specified grade, slope and line. In general, the invention contemplates the machine and implement automatically bringing the pipe section to such specified height or grade, thus bringing the pipe section into position and angular alignment with respect to the specified pipe line, automatically establishing and holding specified slope, and optionally cross-slope, of the pipe section. The pipe section is then linearly inserted into the previously laid pipe section by the operator manually activating the linear insertion actuator.
Abstract:
An apparatus for cutting soil and constructing containment barriers, such as for constructing a subsurface containment walls or bassins for contaminated material, comprises a beam (4) pivoted to a support (6) on the surface for abutting an extended length of soil (2a). The beam (4) comprises a cutting means for creating a cutting action against the extended length of abutting soil. The cutting means is preferably a conduit containing a plurality of jet ports through which high pressure fluid is ejected to impact the soil to be cut. The conduit is preferably rapidly reciprocated. As cutting occurs, the beam (4) and the conduit pivot relative to the support to maintain the cutting apparatus adjacent the face of the soil (2a) to be cut. If the support is mobile, it can advance the cutting action by pulling the beam and conduit beyond the sector through which the beam (4) and conduit can pivot. A method of cutting soil comprises generating cutting action along an extended locus of soil, and advancing the cutting action along a descending locus of the soil (2a) in response to gravity.
Abstract:
Water is removed from an underground perforated pipe (14) by a submersible pump (20) inserted into an imperforate pipe (12) extending from above ground to below ground level for communication with the perforated pipe (14). An inflatable bladder (32) seals the submersible pump (20) to the inner wall (13) of the imperforate pipe (12) for facilitating suction of water from the perforated pipe (14) into the imperforate pipe (12). Water is drawn into a proximal end of the pump (20) and expelled out of a distal end of a pump, and out of the imperforate pipe (12) above ground level. By sealing the pump (20) to the inner wall (13) of the imperforate pipe (12), the pump (20) is capable of drawing water from an underground perforated pipe located at a depth greater that the pumping capacity of the pump (20) for drawing up water.
Abstract:
Bei diesem Verfahren zur maschinellen Herstellung einer Rohrgrabensohle (6) und zum Verlegen von Rohren (8) auf dieser Sohle wird die Rohrgrabensohle (6) etwas größer als die Außenfläche (11) des Rohres (8) im Auflagerbereich in geometrisch gleicher Form ausgehoben. Nachdem das Rohr (8) im Rohrgraben (1) in Position gebracht worden ist, wird ein Schlitzraum (13), der von der Außenfläche (11) des Rohres (8) und der Rohrgrabensohle (6) begrenzt ist, mit Füllmaterial (15) ausgefüllt. Zur Erzielung einer rationellen, arbeits- und kostensparenden Füllmaterialverdichtung wird das Füllmaterial (15) mittels eines Preßluftstromes (19) in den Schlitzraum (13) eingeblasen und dabei unmittelbar verdichtet (Fig. 5).
Abstract:
An apparatus for laying a pipe in a trench comprises a placement assembly 2 for placing the pipe in the trench and a compactor mechanism 3 for compacting of aggregate about the pipe, the compactor mechanism being coupled to the placement assembly. The placement assembly comprises an extendable member which in inserted inside a pipe and withdrawn when the pipe is in place in a trench. The placement assembly may also comprise a means for controlling alignment which may further comprise a laser or other beam emitting device, and a target. The compactor may comprise a pair of reciprocating elongate members which may be moved between a position parallel to the pipe and a position perpendicular to the pipe for compaction. The compactor may be carried on a telescopic arm 11 by means of which it moves along the length of the pipe. The apparatus may be adjusted to cater for a range of pipe sizes.
Abstract:
Novel tools and techniques for installing lines or cables, including, without limitation, power lines, low voltage lines, telecommunications lines or cables (e.g., telephone cables, network cables, television cables, etc.), and/or the like, and, in particular, installing optical fiber and/or other lines, slightly below ground level in a roadway or other ground surface. In some cases, a method might include creating a channel in the ground surface, placing one or more lines (e.g., power lines, low voltage lines, telecommunications lines, and/or the like) in the channel, and placing a capping material in the channel, thereby encapsulating the lines. In some cases, placing the one or more lines in the channel might include placing a conduit (containing the one or more lines) in the channel, and encapsulating the one or more lines might include encapsulating the conduit. The capping material might include polyurea, thermosetting material, and/or any other suitable material.
