摘要:
Methods and apparatus for facilitating a locate and/or marking operation by assessing risk associated with the locate and/or marking operation. A communication interface receives a locate request ticket generated by a one-call center. A processor parses the locate request ticket to extract ticket information obtained from the locate request ticket. The processor further performs a statistical analysis of historical information that is selected based on the ticket information and includes historical damage reports for underground facility infrastructure and/or historical records of previously completed locate request tickets. At least one risk designation is assigned to the locate request ticket based on the statistical analysis of the historical information. The risk designation is transmitted or stored to facilitate clearing the locate request ticket and/or dispatching a locate technician to perform the locate and/or marking operation.
摘要:
Methods and apparatus to evaluate a quality of a locate operation performed at a work site of proposed excavation following issuance of the instruction to a field-service technician. An input/output (I/O) interface receives an electronic manifest of the locate operation. The electronic manifest includes geographic information indicating a first location at which the electronic manifest was created. A distance is determined between the first location and a second location at which the locate operation was requested to be performed. One or more indications of a quality assessment of the locate operation are generated based on whether the distance is within or equal to a predefined range.
摘要:
Methods, apparatus and systems including a computer comprising at least one hardware processor, at least one tangible storage medium (memory), and at least one input/output (I/O) interface for evaluating a quality of a locate and/or marking operation. First information relating to the locate and/or marking operation is compared to second information relating to one or more environmental landmarks. One or more indications of a quality assessment of the locate and/or marking operation is automatically generated based on such a comparison, and the one or more indications of the quality assessment are electronically stored on the at least one tangible storage medium, and/or electronically transmitted via the at least one I/O interface, so as to provide an electronic record of the quality assessment.

摘要:
A method comprises providing a liner to at least a portion of at least one surface, the liner comprising the product of reaction of (a) at least one prepolymer bearing isocyanate groups; (b) at least one polymer bearing isocyanate-reactive groups; and (c) at least one polymerizable reactive diluent; wherein the surface comprises at least one inorganic mineral other than a metal or a glass, with the proviso that the surface is a surface other than a trafficable surface.
摘要:
A liner is the product of reaction of (a) a hydrophilic prepolymer bearing isocyanate groups; and (b) a water-borne polymer dispersion, the polymer bearing groups that are reactive to isocyanate groups; wherein the dispersion has a sufficiently high solids content, and the polymer has a sufficiently high modulus and glass transition or crystalline melting temperature, that the product of reaction exhibits a 24-hour Tensile Strength of at least about 2.5 MPa.
摘要:
The present invention is directed, inter alia, to devices and methods for excavating valuable materials, particularly soft ores such as oil sands, oil shales, and the like, that use one or more of a number of features, including backfilling for ground support, a small trailing access tunnel, processing of the valuable material in the excavation with the tailings optionally being used as backfill and the valuable material being transported to the surface, a plurality of movable shields for ground support, and/or a movable tail shield to provide interim support to the backfill while additional liner sections are installed and/or formed.
