The invention discloses a rock wall crane beam structure and a construction method thereof. The rock wall crane beam structure comprises a rock wall crane beam fixed on a surrounding rock wall surface, and a prestressed anchor rod for connecting surrounding rock with the rock wall crane beam, wherein an anchoring hole is formed in the wall surface of the surrounding rock, a through hole penetrating through the two wall surfaces of the rock wall crane beam in the length direction of the prestressed anchor rod is formed in the rock wall crane beam, the anchoring hole and the through hole communicate to form a containing hole, an anchoring end is formed at one end of the prestressed anchor rod, a locking end is formed at the other end of the prestressed anchor rod, and a free section is formed between the anchoring end and the locking end. The anchoring end is anchored in the anchoring hole, the free section is tensioned in the containing hole, and the locking end is locked on the free surface of the rock wall crane beam. A new force transmission mode is innovatively adopted, so that tensile force is directly transmitted to the deep part of the rock wall, the cement mortar is prevented from being subjected to tension-shear action, the advantage of high compressive strength of the cement mortar in a three-way compressive stress state is brought into full play, the anchoring end isfar away from the free surface, and the stability of a cavern is effectively ensured.

    本发明公开了一种岩壁吊车梁结构及其施工方法,包括固定于围岩壁面上的岩壁吊车梁,以及连接围岩和岩壁吊车梁的预应力锚杆;围岩的壁面上开设有锚固孔,岩壁吊车梁上设有贯穿岩壁吊车梁沿预应力锚杆长度方向两个壁面的通孔,锚固孔与通孔连通形成容置孔,预应力锚杆的一端形成锚固端,预应力锚杆的另一端形成锁紧端,锚固端和锁紧端之间形成自由段;锚固端锚固于锚固孔中,自由段张拉于容置孔中,锁紧端锁紧于岩壁吊车梁的临空面上。本发明创新性地采用新的传力模式,使得拉力直接传至岩壁深处,避免水泥砂浆受拉剪作用,充分发挥水泥沙浆在三向受压应力状态下抗压强度高的优势,锚固端远离临空面,有效保证了洞室稳定。
