Soft foundation construction method for precast concrete piles
The invention discloses a soft foundation construction method for precast concrete piles, which is suitable for a soft soil foundation with a hard shell layer on the upper layer, and comprises the following steps: firstly, punching holes in the hard shell layer on the upper layer, placing the precast concrete piles in the holes, and then vibrating and sinking the precast concrete piles into a soft soil layer below the designed depth; and a part of the top of the precast concrete pile is left in the hard shell layer, and finally the hole above the precast concrete pile is filled with gravel or sandy soil. According to the soft foundation construction method of the precast concrete piles, vibration sinking of the precast concrete piles is carried out in the lower soft soil layer with the designed depth, the bearing capacity of the soil body after construction can be greatly improved, soil body sedimentation is controlled, and in addition, part of the top of each precast concrete pile is left in the hard shell layer, so that the construction cost is reduced. The risk that the pile body slides in a soft soil layer can be effectively prevented, and then the construction effect can be well guaranteed.
本发明公开了一种预制混凝土桩的软地基施工方法，适用于上层为硬壳层的软土地基，所述方法包括：首先在上层硬壳层中打孔并置入预制混凝土桩，然后将预制混凝土桩振沉至设计深度的下方软土层中，并使预制混凝土桩的顶部有一部分留在硬壳层中，最后在预制混凝土桩上方的孔内填入碎石或砂土。本发明的预制混凝土桩的软地基施工方法，由于使用预制混凝土桩振沉是设计深度的下层软土层中，可以大大提升施工后土体的承载力，控制土体沉降，并且，由于预制混凝土桩的顶部有一部分是留在硬壳层中，可以有效防止桩体在软土层中发生滑动的风险，进而能很好的保证施工效果。
