摘要： PROBLEM TO BE SOLVED: To provide a pile construction method with a small removal amount of contaminated soil.SOLUTION: A casing press-fitting step 10 is executed first. That is, a casing is press-fitted to the ground containing the contaminated soil. In the ground, a sand layer, a silt layer, a gravel layer and a support layer are laminated in the order under a contaminated soil layer containing the contaminated soil. The casing is at such a depth that it passes through the contaminated soil layer and the sand layer and reaches the silt layer present under the sand layer. Then, an earth removal step 12 is executed. That is, earth and sand are removed while excavating the inside of the casing. An excavation depth is to the lower end of the casing. Then, a pile construction step 14 is executed. That is, an existing pile is built to the depth to reach the support layer through the inside of the casing. Finally, a casing pull-out step 16 is executed. That is, after constructing the existing pile, while filling soil cement in a gap of the inner peripheral wall of the casing and the outer peripheral wall of the existing pile, the casing is pulled out before the soil cement is hardened.
摘要翻译：要解决的问题：提供具有小的污染土壤去除量的桩施工方法。解决方案：首先执行套管压配合步骤10。也就是说，将壳体压配合到含有污染土壤的地面上。在地下，在含有污染土壤的污染土层下，依次层叠砂层，粉砂层，砾石层和支撑层。壳体处于这样的深度，使其穿过污染的土壤层和砂层，并到达存在于砂层下面的淤泥层。然后，执行地球去除步骤12。也就是说，在挖掘套管内部的同时，移除砂土。挖掘深度为套管的下端。然后，执行桩施工步骤14。也就是说，现有的桩被建立到深度以通过套管的内部到达支撑层。最后，执行套管抽出步骤16。也就是说，在构造现有的桩之后，在将土壤水泥填充到壳体的内周壁和现有桩的外周壁的间隙中的同时，在土壤水泥硬化之前将壳体拉出。版权所有（C）2012，JPO＆INPIT
