目前,一种是就地灌注的抗压混凝土桩,一种是用于抗拉的锚固桩。但在某些结构中,桩往往反复受到压力和拉力的作用。这类桩处于严重疲劳状态,目前还是把一根或几根锚固杆插到地层里,四周裹上混凝土来做这类桩。但这种传统桩可能会因水泥块的破裂渗水而导致锚杆锈蚀。抗压抗拉桩就是要求确保桩底锚固牢靠,即使 At present, one is a compressive concrete pile poured in situ, and the other is an anchoring pile for tensile strength. However, in some structures, piles are often subjected to pressure and tension. These types of piles are in a state of severe fatigue. At present, one or more anchor rods are inserted into the ground and surrounded by concrete to make such piles. However, such conventional piles may cause corrosion of anchor rods due to water seeping through cracking of cement blocks. Compression and tension piles are required to ensure that the bottom of the pile is firmly anchored, even if
