Trench sheets are usually required to monitor the performance of a L8 and FLP 600/3.5 structure either during or after construction If the anchorage is located between bc and bf, only partial resistance is developed due to the intersection of the active and passive failure wedges. Measurements of movements and pressures furnish valuable information for use in verifying design assumptions. However, the theoretical reduction in anchor capacity may be analytically determined.

Most importantly, the data may forewarn of a potentially dangerous situation that could affect the stability of the structure.,FLP600/6 Sheet Pile Anchor Walls - Short steel sheet piles driven in the form of a continuous wall may be used to FLP 600/3.5 trench sheeting anchor tie rods. The ,FLP600/3.5 tie rods are connected with a waling system similar to that for the “parent” interlocking trench sheet wall, and resistance is derived from passive pressure developed as the tie rod pulls against the anchor wall. When a sheet pile L 8 wall is constructed on soft or diversely bedded soil, in areas of high or fluctuating water tables, or is frequently subjected to its maximum loading condition, instrumentation is certainly warranted. However, if the failure wedges do FLP 600/6 intersect, the total passive resistance of the anchor wall will be reduced by the amount.

Trench sheet should depend on site FLP600/6 and FLP700/8 conditions, type of data required, reliability, durability, and ease of construction. To provide some stability during installation of the piling and the wales, pairs of the piling should be driven to a greater depth at frequent intervals. Piezometers. A piezometer is an instrument mainly used for monitoring pore water pressures in foundation and backfill materials. The anchor wall is analyzed by conventional FLP600/3.5 means considering full interlocking trench sheets passive pressure developed only if the active and passive failure zones do not trench sheets intersect. The most common type is the open tube or open stand pipe piezometer, offering both simplicity and reliability. Thoroughly clean interlock with wire wheel brush (or hand brush)Remove grit and debris from interlock by blowing. Pore pressure data can be used in an effective stress analysis, which can indicate a state of impending FLP700/8 failure not apparent from a total stress (Q) analysis. If oil is present in interlock, heat to remove oil FLP 700/8 by acetylene torch.

Trench sheeting FLP 600/6 and FLP 700/8 must be clean and dry. Also from these piezometers a general foundation zone permeability can be estimated for use in seepage analyses. Piezometers attached to the sheet pile prior to installation should be protected from possible damage during driving. Installing piezometers, after driving or backfilling the sheet pile, becomes more difficult. The stub must be high enough to level the trench sheet pile (see detail). Since the beams are level,the pile should be level. (this is critical - Piles must be level. The level must be maintained until the A-30 is cured.)

Interlocking trench sheet are generally used for measuring L 8 and FLP600/3.5 lateral displacement of foundations and embankments but can be used to monitor horizontal movements in sheet pile walls. The more common types employ a casing of either plastic, aluminum, or steel installed in a vertical bore hole or securely attached to the surface of a sheet pile. Set piles in position so the socket is open and easily accessible. If piles are singles (not paired) place two steel beams parallel and level across the beams. Weld stub on one beam to support the “up” side of the FLP600/6 pile. Normally, the lower end of the inclinometer casing is anchored firmly in rock to prevent movement at trench sheeting this end, thus serving as a reference point. Remove (with grinder) any rough or sharp edges on the leading interlock (male side). The treated L 8 interlock (female side) will be driven over the male side. Any rough or sharp edges may damage the bead of A-30. If a rock interlocking trench sheeting anchor is not available, the lower end should penetrate a minimum of 15 feet in soil that will not experience movement. The tie rod connection to the anchorage should be ideally ‘ located at the point of the resultant earth pressures acting on the anchorage.

Use urethane foam, L8 pieces of closed FLP700/8 cell backer rod or similar material to dam ends of interlock. Inclinometers attached to trench sheets sheet piles are limited to the length of the pile if they are to survive driving. This limitation does not permit data collection for movements occurring below the tip. Measuring and FLP 600/3.5 Mixing - The A-30 is a two component material. Measure the 15:1 ratio (15 parts resin and 1 part hardener) carefully and mix thoroughly. For these cases an additional inclinometer, which penetrates into a nonmoving deep formation, may be warranted. - measure carefully and mix well. Do not mix more than you can apply within 2 hours. One pail or resin and one can of hardener will yield 4 gallons. POT LIFE is approximately 2 hours!The effects of interaction of the active and passive failure surfaces, as mentioned above, also apply to the design of deadmen anchors.

The most common FLP 600/6 strain gauges used for monitoring sheet pile structures are of the electrical resistance and vibrating wire type. Mixing is complete when the amber color is equal throughout the mixture. Two quarts of resin trench sheet will require 4.25 ounces of hardener. These gauges are designed to measure minute changes in a structural dimension, which can then be converted to a stress, load, or bending moment. Or another example 7.5 quarts of resin will require 0.5 quarts of hardener. If the FLP 700/8 material is not measured correctly and mixed well, it may not cure or expand as intended. The electrical resistance strain gauges are made so that they can be easily attached to a surface by means of an epoxy adhesive or by welding.
