¡¡¡¡Corrugated culvert life is used in the office environment, can guarantee the normal office of the shortest time line or loop back office number. Made of corrugated culvert elastic sealing system, often in the office of the bear more recycled back to the changes in the number of load and larger displacement, because this confirmation corrugated culvert use life, has important significance. Because the corrugated culvert utility is not the same, the using life of the requirements are also different. Corrugated culvert office in compression conditions permitted compression displacement than allowed tensile displacement in the office of the tensile condition to the point, so in the preset corrugated culvert should as far as possible to make corrugated culvert in the office of the compression condition. After the experiment found that, in general, a corrugated culvert pipe with same material, the same specifications, which allow the compression displacement is 1.5 times the tensile displacement allowed. For the office in corrugated culvert compression condition, its maximum compression displacement is: corrugated culvert under pressure under compression utility, to the maximum displacement between you and I contact each other corrugated by initiation of the value, also known as the structure to allow maximum displacement, it is equal to the free length and the maximum compression corrugated culvert length difference.
¡¡¡¡(1) a corrugated culvert pipe system effectively to pay for the position deviation caused by the installation, the life is only a few times is enough.
¡¡¡¡(2) constant temperature controller corrugated culvert effectively to switch frequency higher, its life to reach 10000 capacity to meet the application requirement.
¡¡¡¡(3) corrugated culvert effectively in vacuum switch as the vacuum tight closure, the life would be 30000 times the ability to guarantee the normal office.
