14. Anchoring Pipes on Steep Slopes.

1) Pipe Slopes twenty (20%) percent to under fifty (50%) percent. a) Concrete anchors for DIP and AWWA C900/905 PVC pipe, 24-inch diameter and smaller, are to be according to the Standard Detail M/4.0. b) On profile show the concrete anchor and the spacing in accordance with Standard Detail M/4.0. Space the anchors depending on the pipe slope. HCI Helical Piers and Anchors of Texas, Oklahoma, New CHANCE Helical Piers. The earliest known use of an anchor foundation was for the support of lighthouses in tidal basins around England. A blind English brickmaker, Alexander Mitchell, is credited with the design of a "screw pile" for this purpose in 1833.

Helical Piles - What an Engineer Needs to Know - Articles The engineer can use the relationship between installation torque and load capacity to establish minimum torque criteria for the installation of production helical foundations. The recommended default values for Kt [10 for square shaft and 7 for 32 -inch OD pipe shaft] will typically provide conservative results.

This dragging force equates to less than 0.054 ksi or less than 0.18% specified minimum yield strength (SMYS) of the pipe. The support anchors are designed to provide stability to the pipeline where spans develop. By design, the anchor supports can de- Piling AnchorsFast, easy, affordable foundations. 1(19) Spread; raft; & pile foundations; walls & other structures retaining or supporting soil or water; excavations; bridge piers & abutments;

Potential Advantages and Limitations - Helical Foundations

Potential Advantages of Using Screw-Piles and Helical Anchors. A1. Rapid Installation. Screw-piles and helical anchors are usually installed using conventional construction equipment such as a track excavator or a mini-excavator equipped with an appropriately sized low SCREW ANCHORS ECONOMICALLY CONTROL PIPELINE For an application where the screw anchor shaft is in tension (for example, pipeline buoyancy), the shaft is typically made from 38 mm (1.5 in.) square solid steel and is 1.8 m (6 ft) to 3.0 m (10 Spiral Welded Pipe - Nucor SkylineThe difference is the coil is wound at an angle, so the weld runs around the outside of the pipe in the shape of a helix. This allows for a lot more variation in diameter and thickness than ERW pipe. Spiralweld pipe is most commonly used for pipe diameters between 24 in. and 120 in. and for thicknesses of 1.0 in. or less. Manufacturing Process

This technology eliminates the costs and hazards of weights traditionally used for marine buoyancy control. The leading edge in helical foundationsof helical anchors. Contractors used a configuration consisting of 1-1/2 RCS solid steel square shaft 8-10-12 lead helices with an ultimate capacity of 3,400 pounds. The top row of anchors were installed to 17 feet with a design load of 7 KIP. The second row was installed to 14 feet with a capacity of 21 KIP.

TerraTorque Inc - Pipeline Helical (Screw) Anchors

Pipeline helical (screw) anchors have been used for decades in the oil and gas pipeline industry. They are a well established technology recognized worldwide as an economical and practical solution for onshore pipeline buoyancy control, offshore pipeline buoyancy control, offshore pipeline stabilization and pipeline span rectification.
