Construction method for compression-resistant and pulling-resistant end bearing pile in soil
According to the construction method for the compression-resistant and pulling-resistant end bearing pile in the soil, a reinforced concrete drill bit and a steel pipe pile are pressed into the soil in a static pressure mode, the steel pipe pile is pressed till the pile tip makes contact with the rock surface, and then a certain number of reaming self-locking anchor rods are installed in the steel pipe pile; the anchor rod enters a rock layer by a specified depth by drilling through the pile tip and is self-locked, then a reinforcing mesh is placed in the steel pipe, common concrete is poured, and the self-locking anchor rod and the steel pipe pile are connected into a whole, so that the force among the pile bottom, the pile body and the soil layer can be effectively transmitted, and the compression resistance and the pulling resistance are effectively improved.
本发明公开的一种用于土中抗压和抗拔端承桩的施工方法，通过利用钢筋混凝土钻头和钢管桩静压入土中，钢管桩静压至桩尖接触岩石表面，接着在钢管桩内安装一定数量的扩孔自锁锚杆，锚杆通过钻穿桩尖进入岩石层内规定深度并自锁，然后在钢管内放置钢筋网、灌注普通混凝土，扩孔自锁锚杆与钢管桩连接成一个整体，这样就能有效传递桩底、桩身与土层之间的力度，有效提高抗压、抗拔的性能。
