As long as dynamic operation is carried out on the granular foundation or on the stratified foundation containing granular soil, the sheet pile used for liquefaction can exist in SKZ 31 or SKZ 33. If the installation of the sealant system and the storage and driving will follow the SKZ 33, the resistance of the reverse joint is p = 3 x 10-10 M / S (9.8 x 10) -10 ft / sec if the SKZ 31 ProfilARBED is purchased. The reverse SKZ 34 joint below the SKZ34 pull rod reAny soft soil, even at a very large depth, may be consolidated under the weight of the nearest backfill, causing land subsidence sheet piles for sale. The risk of liquefaction should be assessed on a case by case basis according to the technical report GL-88-9 (Torrey 1988).
The steel sheet pile is usually a circular structure SKZ 34 or SKZ 36 or SKZ 38 steel bar with upsetting thread ends to avoid reducing net area due to thread. To eliminate laxity, screws are usually provided in each pull rod. The distance is determined in 200 field tests, in which a special test device is used to measure the SKZ33 discharge through the joint (with Roxan seal) as a function of the pressure drop applied (see the "first part"). The soil meets the standard of this report, and it is assumed that the acceleration of soil particles in the process of piling will be SKZ36 enough to cause liquefaction, and small settlement will lead to the droop of the rod under the weight of the soil above it. This droop will cause the tensile stress of the SKZ 38 bar to increase because it tends to SKZ 36 to pull the sheet. Nevertheless, safety factors applicable to this value should be carefully chosen, taking into account the dispersion of data and the inherent risks of projects. Therefore, there is potential damage. Then we should limit the piling, for example, the maximum water level during SKZ34 driving. In order to eliminate this situation, one of the following methods can be used: 1. Use SKZ 38 light vertical piles to support pull rods at intervals of 20 to 30 feet. 2. put anchor into the large pipeline and keep the minimum distance from the sediment of liquefaction prone soil; the size and rated energy of SKZ36 pile hammer. The horizontal response from the anchored sheet pile wall is passed to the pull rod through a longitudinal bending member. Complete prohibition of driving may be necessary.
SKZ31 and SKZ33 piling have been successfully applied to the embankments of the Mississippi and Atchafalaya rivers. Although the Roxan system has been strictly tested, ProfilARBED and / or Adeka Ultra Seal can not be liable for damage caused by improper use or improper use in any case. It usually consists of two spaced structural steel SKZ33 channels, and their web plates are placed back-to-back in horizontal position. It is based on the possibility of stage liquefaction at the water level above the land surface to prevent or limit the piling, and plan to carry out piling or flood control SKZ38 work within 1500 feet of the dam. The channels are spaced enough between their web plates to remove the upsetting ends of the pull rods. Any SKZ38 restrictions on piling should be assessed to prevent damage to the public.
The pull rod placed above the loose granular or soft clay can bear the load pipe section or other types of separators to maintain the required spacing when the channels are connected together. It is obvious that only when SKZ 33 is sufficiently embedded in the impervious layer to avoid significant flow around the pile foot, good SKZ38 results can be obtained. A value larger than a traditional method. Due to potential SKZ31 soil compression, whether it is due to volume change, distortion or consolidation, the weight of overlying soil will cause additional load when the rod deflects.
