Pound grade stakes into the ground on each end of the area you need sloped. How to calculate cubic yards for rectangular, circular, annular and triangular areas. You don't need a slope percentage calculator most of the time if you already have the slope; just multiply by 100, or equivalently, and move the decimal point in the slope two places to the right. Multiply the number of feet of your pipe (X) by the inches you’re planning to slope the line (Y). Note 2: These are the minimum sloping requirements. As an example, let’s calculate the slope angle of a simple trench that is 6 feet deep by 2 feet wide, factoring in the type of soil. Calculate a slope, a gradient, a tilt or a pitch Calculating a Slope from the Length and Height. 1. Whether is be a 10 feet deep 3 feet wide trench for pipe installation or a large excavation for a building basement the OSHA requirements are very clear on the safety guidelines required for a safe work area. The stake at the top of the slope is called the hinge. Measure the length of the trench. Excavation in sharp sand should be sloped 1 1/2 unit for each unit depth. To/ Reader You’ve asked this question. Now divide the number by 8 to learn how much deeper one end of the pipe must be to achieve a slope of 1/8" per foot. You can also use the attached trench drain calculator to complete your trench drain design. Before placing your pipe, use this formula to determine the slope and create a sewer pipe slope chart to follow. Trench Excavation Slope. a) To determine the pipe distance for 48-inch and larger sewers in circular manholes, determine "If the slope is tall, you will need to crawl up to the top and pull your grade down to the toe. Place a stake in the ground at the highest point on the slope you wish to calculate. 3) Pipe slope and distance for sewer pipelines 48-inch and larger diameter. They assume sandy loose soil so slope distance is equal to 1.5:1. The Slope Calculator Tool was created to assist construction professionals with the design of excavation and trenching operations. Make a new mark on the second stake this distance below the mark you recently made to show level. Hold the slope angle tool horizontal and perpendicular to the sides of the slopes (kneel down to get close to the horizontal). Lay a tape measure along the ground adjacent to the trench or along the base of the trench if that is flatter. Record the length. The field quick angle slope tool gives you and your team an advantage when excavating to install underground utilities. The horizontal distance from top of slope to bottom of slope 2. Stability of slopes in open excavation in different soil condition along with the factors that control slope stability in open excavation are discussed. 1. Calculate cubic yards, cubic feet or cubic meters for landscape material, mulch, land fill, gravel, cement, sand, containers, etc. Example 1: If you have 10 feet of pipe, and you’d like to slope your pipe ½ inch per foot, your equation would be 10 x ½ = 5 inches.
