Method for bridging and reinforcing side slope crack by using anchoring structure
The invention provides a method for bridging and reinforcing a slope crack through an anchoring structure, the anchoring structure comprises a frame beam, a free section and an anchoring section, the free section and the anchoring section are communicated, the free section comprises an inner grouting pipe, an outer grouting pipe and a middle section grouting and bridging device, one end of the outer grouting pipe is communicated to the anchoring section, an outer pipe opening is formed in the middle section of the outer grouting pipe, and the middle section grouting and bridging device is communicated with the outer pipe opening. The middle-section grouting bridging device is arranged at an outer pipe opening of the outer grouting pipe and provided with a grout outlet hole, and one end of the inner grouting pipe extends into the outer grouting pipe, extends to the middle-section grouting bridging device along the outer grouting pipe and is communicated and rigidly connected with the outer grouting pipe. During reinforcement, specific parameters of the anchoring structure are determined through detection, so that the middle-section grouting bridging device is located at a crack forming surface or a soft soil layer range, after primary grouting condensation, the outer grouting pipe is tensioned to enable the frame beam to extrude a soil body so as to enable the cracks to be in close contact with one another, and then slope cracks are bridged and reinforced through secondary grouting. And the effect of gradually stabilizing the slope is achieved.
本发明提供一种利用锚固结构对边坡裂隙弥合加固的方法，所述锚固结构包括框架梁、相连通的自由段和锚固段，自由段包括：内注浆管、外注浆管和中段注浆弥合装置，外注浆管的一端连通至锚固段，在外注浆管的中段处设有外管开孔，中段注浆弥合装置设置在外注浆管的外管开孔处，中段注浆弥合装置具有出浆孔，内注浆管的一端伸入外注浆管的内部且沿外注浆管延伸至中段注浆弥合装置并与之连通且刚性连接。加固时，通过探测确定锚固结构的具体参数，使得中段注浆弥合装置位于裂隙形成面处或软弱土层范围处，初次注浆凝结后，张拉外注浆管致框架梁挤压土体使得裂隙紧密接触，之后通过二次注浆，对边坡裂隙弥合加固，达到边坡逐渐稳定的效果。
