The invention discloses a perforated semicircular anchor wing power penetration anchor capable of enhancing in-place bearing capacity, which comprises a semicircular anchor wing and a counterweight feeler lever, wherein the semicircular anchor wing and the counterweight feeler lever are connected by a plate anchor connecting sleeve, and water permeable holes are uniformly distributed on the semicircular anchor wing. By means of the designed water permeable holes, the drainage condition of the semicircular anchor wing dynamic penetration anchor is effectively improved. In the penetration process of the penetration anchor, the sinking water resistance is not increased, and compared with a traditional power penetration anchor, the construction cost is not increased; positive and negative porepressures on two sides of the anchor body are continuously balanced due to the existence of the water permeable holes, and meanwhile, the generated pore water pressure is continuously dissipated dueto the increase of the drainage paths, so that the disturbed and weakened soil body strength is quickly recovered, and the pulling resistance of the anchor is greatly improved. The advantages of beingsimple in structure, convenient to install and high in reutilization rate are also achieved.
本发明公开了一种可增强在位承载力的打孔半圆形锚翼动力贯入锚,包括半圆形锚翼和配重探杆,所述的半圆形锚翼和配重探杆由板锚联接套筒连接,半圆形锚翼上均匀布置透水孔。本发明所设计透水孔,有效改善半圆形锚翼动力贯入锚的排水条件。在贯入锚的贯入过程中,不会增加下沉水阻力,与传统动力贯入锚相比不会增加施工成本;透水孔的存在使得锚体两侧的正负孔压不断平衡,同时排水路径的增多使得产生的孔隙水压力不断消散,从而受到扰动而减弱的土体强度迅速恢复,使得锚的抗拔能力大大提升。同时本发明还具有结构简单、安装便捷和重复利用高的优点。
