Concrete prefabricated pipe pile only bearing anti-drawing effect
The invention belongs to the field of constructional engineering, and particularly relates to a concrete prefabricated pipe pile only bearing an anti-drawing effect. The concrete prefabricated pipe pile only bearing the anti-drawing effect comprises a concrete prefabricated pile body, a detachable hollow guide rod and a metal pile tip. The concrete prefabricated pile body is provided with a pile top and a pile bottom. The concrete prefabricated pile body is driven into foundation soil. The detachable hollow guide rod is arranged in a cavity of the concrete prefabricated pile body, a pile tip connecting thread is arranged at the bottom end of the detachable hollow guide rod, a guide rod connecting thread is arranged at the top end of the metal pile tip, and the detachable hollow guide rod is in threaded connection with the metal pile tip. The concrete prefabricated pipe pile has the following beneficial effects that the metal pile tip is arranged on a pile tip of the concrete prefabricated pipe pile, pile sinking pierces into soil mass to more easily penetrate through a hard soil layer, the efficiency of pile sinking is improved, and disturbance for the surrounding soil mass is reduced; and the pile tip can be recycled, a cavity can be formed between the pile tip and the foundation soil, the purpose of saving materials is achieved, the size of the metal pile tip can be customized, and the use range is wide.
本发明属于建筑工程领域，具体地，涉及一种仅承受抗拔作用的混凝土预制管桩。仅承受抗拔作用的混凝土预制管桩，包括：混凝土预制桩身、可拆卸空心导杆、金属桩尖，混凝土预制桩身具有桩顶、桩底，混凝土预制桩身打入地基土中；混凝土预制桩身的空腔内设有可拆卸空心导杆，可拆卸空心导杆底端设有桩尖连接螺纹，金属桩尖顶端设有导杆连接螺纹，可拆卸空心导杆与金属桩尖螺纹连接。本发明具有如下有益效果：金属桩尖至于混凝土预制管桩桩尖，使得沉桩刺入土体更加容易穿过坚硬土层，提高沉桩的效率，减少对周边土体的扰动；桩尖可回收重复利用，可以在桩尖与地基土之间形成空腔，节省材料的目的，金属桩尖大小可以定制，使用范围广。
