Pre-stressed pipe pile planting construction technology
The invention discloses a pre-stressed pipe pile planting construction technology, and relates to the technical field of civil engineering, the pre-stressed pipe pile planting construction technology comprises the following steps: S1, preparing slurry, and mixing concrete or mortar with water to form the slurry; s2, drilling and grouting are conducted, drilling is conducted on the ground to form pile holes, and grouting and stirring are conducted; s3, a front precast pile is implanted, specifically, the front precast pile is vertically implanted into the pile hole, and the front precast pile is tamped, so that the front precast pile is only exposed out of the pile hole by 800mm-1000mm; s4, positioning a rear precast pile, hoisting the rear precast pile, placing the rear precast pile on the front precast pile, and horizontally moving the rear precast pile, so that the rear precast pile is adjusted to be coaxial with the front precast pile; s5, a rear precast pile is locked, the rear precast pile is fixed to the end of the front precast pile, and a composite pile is formed; and S6, the rear precast pile is implanted, the end of the composite pile is tamped, so that the front precast pile enters the pile hole, and the steps S3, S4 and S5 are repeated till the composite pile is completely implanted into the pile hole. The precast pile butt joint device has the effect of improving the butt joint efficiency of the two precast piles.
本申请公开了一种预应力管桩植桩施工工艺，涉及土木工程技术领域，其包括以下步骤：S1.配置浆液，将混凝土或砂浆与水混合形成浆液；S2.钻孔并注入浆液，对地面钻孔形成桩孔并注入浆液搅拌；S3.植入前预制桩，向桩孔中竖直植入前预制桩，并夯击前预制桩，使得前预制桩仅露出桩孔高度800mm~1000mm；S4.后预制桩定位，将后预制桩吊起并放置在前预制桩上，水平移动后预制桩，使得后预制桩被调整至与前预制桩共轴线；S5.后预制桩锁定，将后预制桩固定在前预制桩的端部，形成复合桩；S6.植入后预制桩，夯击复合桩端部，使得前预制桩进入桩孔中，并重复上述步骤S3、S4、S5，直至复合桩全部植入桩孔中。本申请具有提高两个预制桩对接效率的效果。
