Abstract: The present invention relates to a pulling resistance testing box for earth nail. Said testing box includes the following several portions: a testing box main body with first additional chamber and second additional chamber, rock and soil sample, earth nail, an upper cover plate, a rubber water bag and a pulling force applying device. Said invention also provides the concrete structure and mounting mode of the above-mentioned every portion and the working principle of said testing box.
一种土钉抗拔力测试箱,包括:一测试箱主体,其左右两侧面(即土钉的尾部和前部)分别凸设有与该测试箱主体相连通的一第一附加室和一第二附加室,在该测试箱主体和该第一附加室内充填有岩土样本;待测试的土钉设置在该测试箱主体中;一上盖板,可拆卸地连接到该测试箱主体的上端,用于封闭该测试箱主体;一橡胶水袋,设置在该上盖板的下表面与该岩土样本的上表面之间,用于对该岩土样本施加垂直方向的压力;一拉拔力施加装置,设置在该测试箱主体的该第二附加室一侧,该拉拔力施加装置与该土钉的另一端连接,用于对该土钉施加拉拔力;当该测试箱工作时,测量施加到该土钉上的拉拔力和该土钉在该拉拔力作用下的位移,可以得到该待测试土钉的抗拉拔能力。
