Technique for establishing and recording a boring tool path using a survey reference level
First Claim
1. In an overall process in which a boring tool is moved through the ground within a given region along a particular path from a specific starting point, a method of establishing the location of at least a portion of said particular path within the given region, said method comprising the steps of:
- (a) establishing within the region (i) a vertical survey reference level and (ii) a reference path;
(b) providing a portable locator and information generating means for generating certain information about the position of the boring tool relative to the position of the locator, said information generating means being located partially at said boring tool and partially at said locator;
(c) when said boring tool reaches various spaced-apart locations as it moves along the particular path, at each such location positioning the locator on the reference path at an associated reference point which is specifically determined by the position of the boring tool at the associated location on the particular path;
(d) with the locator positioned at each of said reference points, generating and recording the positional information of the boring tool at the associated location on the particular path; and
(e) from the recorded information of the boring tool at the various associated locations on the particular path, establishing an after-the-fact path containing the associated locations such that the associated locations are known locations with respect to both said reference path and said vertical survey reference level, said after-the-fact path corresponding generally to at least a portion of the particular path taken by the boring tool, whereby even if the reference path changes in time due to a change in the terrain vertically defining the reference path, the after-the-fact path will still be able to be located with respect to said vertical survey reference level.

Abstract
An overall process in which a boring tool is moved through the ground within a given region along a particular path from a specific starting point is disclosed herein. A method of establishing and graphically recording the location of at least a portion of the particular path taken by the boring tool within the given region is also disclosed herein along with and with respect to a reference path which may change with time and vertical survey reference path which will remain unchanged with time.

18. In an overall process in which a boring tool is moved through the ground within a given region along a particular path from a specific starting point, a method of graphically establishing the location of the particular path within the given region, said method comprising the steps of:
-
(a) establishing within the region (i) a vertical survey reference level and (ii) a reference path; (b) providing a portable locator and means for generating certain information about the position of the boring tool relative to the position of the locator said means being located partially at said boring tool and partially at said locator; (c) when said boring tool reaches various spaced-apart locations as it moves along the particular path, at each such location positioning the locator on the reference path at an associated reference point which is specifically determined by the position of the boring tool at the associated location on the particular path; (d) with the locator positioned at each of said reference points, generating and recording the positional information of the boring tool at the associated location on the particular path; and (e) from the recorded information of the boring tool at the various associated locations on the particular path, establishing and graphically representing said reference path, said vertical survey reference level and an after-the-fact path containing the associated locations such that the associated locations are known locations with respect to both said reference path and said vertical survey reference level, said after-the-fact path corresponding generally to at least a portion of the particular path taken by the boring tool, whereby even if the reference path changes in time due to a change in the terrain vertically defining the reference path, the after-the-fact path will still be able to be located with respect to said vertical survey reference level. - View Dependent Claims (19)

-
(a) establishing within the region (i) a vertical survey reference level and (ii) a reference path; (b) providing a portable locator and information generating means for generating certain information about the position of the boring tool relative to the position of the locator, said means being located partially at said boring tool and partially at said locator; and (c) using said portable locator, said information generating means, and additional means, establishing and graphically representing said reference path, said vertical survey reference level and an after-the-fact path corresponding generally to the particular path taken by the boring tool, whereby even if the reference path changes in time due to a change in the terrain vertically defining the reference path, the after-the-fact path will still be able to be located with respect to said vertical survey reference level. - View Dependent Claims (21)
