沙井袋
Sand well the bag

P18  

  沙井袋是一种抗拉强度较高,透水透气性好,耐酸碱腐蚀和微生物侵蚀的材料。采用沙井袋打砂桩,利用沙井袋的隔离、渗透功能和砂子的渗透性能,可加速软土地基的固结,缩短固结时间,加快施工进度,并大大节约砂子用量,是进行软土地基处理的有效方法。因此被广泛应用于公路、铁路、机场、港口、堤坝等软土地基处理工程中。
  Sand well the bag is a kind of anti- to pull the strength higher,water the well ventilated is good,and the acid-proof alkali decay with the material that the microorganism erode.Adoption sand well the bag beatthe sand stake the valid method for insulation for,make use of the sand well the bag,permeating the function with permeating of sand son function,can accelerating the knot of the soft soil using measuring ,is proceeding soft soil foundation handling,Extensive of for this reason quilt Used for the highway,railroad,Airport,Port,Dike,The soft soil foundation of etc.handles the engineering the inside.
