Variable cross-section mortise and tenon assembly type precast pile and construction method
The invention discloses a variable cross-section mortise and tenon assembly type precast pile which comprises a bottom pile, the bottom pile is vertically, upwards, coaxially and sequentially connected with a plurality of groups of precast piles, the lower ends of the precast piles are coaxially and fixedly connected with the top end of the bottom pile, and the inner diameter of each group of precast piles is larger than that of the lower adjacent group of precast piles. Mortise and tenon grooves are formed in the bottom ends of the inner walls of each group of precast piles above the first group of precast piles, the inner diameter of each mortise and tenon groove is larger than the outer diameter of the adjacent group of precast piles below and is not smaller than 30 mm, and the depth of each group of mortise and tenon grooves is set to be 1.2 times of the diameter of the top face of the adjacent group of precast piles below. And the top ends of the outer walls of each group of precast piles are coaxially embedded into the mortise and tenon joint grooves in the bottom ends of the inner walls of the adjacent group of precast piles above. The bottom piles and the precast piles are arranged to meet the rule that the upper sections of the upper sections are large in size and the lower sections are small in size in load transmission; and the lower group of precast piles and the upper group of precast piles are connected through mortise and tenon grooves which are not smaller than 1.2 times of the outer diameter of the upper group of precast piles, so that the piles can be conveniently aligned and connected.
本发明公开了一种变截面榫卯装配式预制桩，包括底桩，底桩垂直向上同轴依次连接有多组预制桩的下端与底桩的顶端同轴固定连接，每组预制桩的内径尺寸均大于下方相邻一组预制桩的内径尺寸，第一组预制桩上方的每组预制桩内壁底端均开设有榫卯槽的内径尺寸均大于下方相邻一组预制桩的外径尺寸且不小于30mm，每组榫卯槽的深度均设置为下方相邻一组预制桩顶面直径的1.2倍，每组预制桩的外壁顶端均同轴嵌入上方相邻一组预制桩内壁底端的榫卯槽中，本发明中的底桩和预制桩均设置为符合荷载传递上大下小规律的上节截面尺寸较大，下一组预制桩与上一组预制桩之间通过不小于上一组预制桩外径尺寸1.2倍的榫卯槽连接，便于对齐接桩。
