Applications and Setups This chapter describes three fundamentals for using the Model DG511/711 to install gravity flow pipe; they are Grade, Elevation, and Line, otherwise known as G-E-L. To install gravity flow pipe, the pipe is set to a percentage of Grade that has been determined by some engineered plans. The gravity flow pipe is designed to be set to some engineered Elevation. Finally, the gravity flow pipe will be installed between two designed points, therefore defining Line.
5 Applications and Setups Grade 5.1 Grade establishes the slope of the pipe and is generally displayed in percent (%). A rise of 1 m (1ft) over a run of 100 m (100 ft ) equals 1.00%. The process for setting up the Model DG511/711 remains the same. The laser beam shall be sloped to match the plans. The Elevation of the pipe or cut to invert is given from the plans at which the laser shall be used to control that elevation, and finally set the laser on Line to match the orientation of the pipe run.
Applications and Setups When setting the laser, a surveyed manhole grade hub must be available to set the laser at the proper elevation and the pipe will be installed at the correct elevation. Setup, Step-byStep Set Grade 5 5.4 5.4.1 Press the positive or negative grade button to set the Laser at the correct grade as determined by the engineered plans. 1 Line 5.3 Line ensures proper direction of the pipe run between manholes according to the engineered plans.
5 Applications and Setups Set Elevation for Small In-the-Pipe or Pre-cast Inverts 5.4.2 1 The laser automatically centers in the 150 mm (6 inch) diameter pipe and pre-cast inverts without additional accessories. 3 Use the following chart to determine how to set up the laser so the laser beam is centered in the following pipe sizes. 2 The laser automatically centers in 200 mm (8 inch) diameter pipe with the 1238 mounting plate. Table 5.

Refraction 7 7 1 Refraction is the bending of light at the interface of two substances caused by a difference in the speed of light. Shooting a laser beam through a pipe having gas and varying temperatures can be compared to shining a flashlight beam into a pool of water and seeing the light bend. Refraction of the laser is preceded by what appears to be a flaming of the laser spot at the edges. When this occurs, it is time to mix the air within the pipe by some external means such as a blower.
7 Refraction joints of the pipe have not had a chance to cool in the shade of, and against the earth of the trench. 6 If possible, always back-fill the pipe as you go. The earth is a great temperature stabilizer as it surrounds the pipe. The earth tends to stabilize the temperature of the pipe and the air inside. Use of a blower in conjunction with backfilling accelerates temperature stabilization. Always back-fill immediately unless the jobsite condition makes it impossible.
11 If the beam still can not be controlled, have your backhoe excavate five buckets full and then one or two empty buckets as if it were bailing water. The blower is pushing heavy fumes in the pipe that can not get out of the trench without someone’s help. Cast the empty bucket on the low side of the surface or on the downwind side of the cut.
7 Refraction 4 Start the blower with the first section of pipe. Use the table on the blower to determine the blower speed from the length and size of pipe being installed. Although very unlikely, be aware too much air can also cause refraction.

Calibration 9 CHAPTER 9 Checking the Calibration 9.
9 Calibration Checking the calibration of your pipe laser is easy. All you need is an engineer’s rule and your pipe laser: 1 Select a level road, parking lot or field whose rise is not more than 10 cm in 30 m (4 inches in 100 ft). Choose two points (A and B) about 30 m (100 ft) apart. The distance does not have to be measured, but the points must be found, so mark them well. 2 3 Set up the pipe laser just behind the lowest point and rough level.
9 Calibration 12 Subtract the A1 and B1 elevation readings from A2 and B2 elevation readings. Note – Your laser is in calibration if the difference between A2 – A1 equals B2 – B1. Note – If A2 – A1 is greater than B2 – B1, the laser beam is shooting high and you should readjust the laser’s calibration bringing the beam to level. Note – If A2 – A1 is less than B2 – B1, the laser beam is shooting low and you should readjust the laser’s calibration bringing the beam to level.
9 Calibration Grade Check 9.3 A B After the first 8–15 m (25–50 ft) of pipe has been laid, it is recommended that you make a grade check to ensure that the setup is correct, and that the system is properly operating. 3 The difference between the readings equals the rise over the run. The illustration shows a method for checking grade.
