Variable cross-section cemented soil core-inserted composite pile, construction device and method
The invention discloses a variable cross-section cemented soil core-inserted composite pile, a construction device and a method, and belongs to the field of civil engineering. Materials can be saved,a core pile is selected according to different stratums and upper structure bearing requirements, and the bearing capacity is high. The variable cross-section cemented soil core-inserted composite pile comprises a main pile body and the core pile located in the main pile body. The length of the core pile is not greater than that of the main pile body. The main pile body is provided with a first end face and a second end face, the diameter D1 of the first end face is greater than the diameter D2 of the second end face, the diameter D2 of the second end face is greater than the diameter d of thecore pile and is greater than 0.8 D1, and the end portion of the main pile body can be connected with an expansion head.
本发明公开了一种变截面水泥土插芯组合桩、施工装置及方法，属于土木工程领域，能节约材料，根据不同的地层及上部结构承载要求进行芯桩的选择，承载力高，包括主桩体和位于主桩体内的芯桩，芯桩长度不大于主桩体长度，主桩体具有第一端面和第二端面，第一端面直径D大于第二端面直径D，且第二端面直径D大于芯桩直径d且大于0.8D；主桩体的端部还能够连接扩大头。
