Protective device for high and steep slope at tunnel portal
The invention provides a protection device for a high and steep side slope of a tunnel portal, which comprises a protection net, a plurality of groups of anchoring mechanisms for fixing the protection net on the side slope and reinforcing plates connected between every two adjacent anchoring mechanisms, and each group of anchoring mechanism is respectively arranged at each corner position of the protection net; the anchoring mechanism comprises a pre-embedded anchor seat pre-embedded in the side slope soil and an anchor rod piece fixed to the pre-embedded anchor seat, the anchor rod piece and the pre-embedded anchor seat jointly clamp and fix the protective net, and the anchor rod piece penetrates through the pre-embedded anchor seat and is anchored in the side slope soil; the reinforcing plates are connected between the adjacent pre-embedded anchor seats, positioning nails are arranged on the side faces of the reinforcing plates, and the positioning nails penetrate through the protective net and are anchored in the slope soil. On the basis, the reinforcing plate pieces, the pre-embedded anchor seats and the anchor rod pieces jointly form an integral anchoring system of the protective net, when the local position is loosened, the influence on the integral anchoring system is small, and the protective net can keep good protective capacity.
本申请提供了一种隧道口高陡边坡的防护装置，包括包括防护网、用于将防护网固定于边坡的多组锚固机构以及连接于每两相邻锚固机构之间的加固板件，各组锚固机构分别设置于防护网的各个边角位置；锚固机构包括预先埋设于边坡土壤内的预埋锚座以及固定于预埋锚座的锚杆件，锚杆件与预埋锚座共同夹持固定防护网，且锚杆件穿设于预埋锚座并锚固于边坡土壤内部；加固板件连接于相邻预埋锚座之间，且加固板件的侧面设有定位钉，定位钉穿过防护网并锚固于边坡土壤内部。基于此，加固板件、预埋锚座和锚杆件共同形成防护网的整体锚固体系，当局部位置出现松脱时，对整体的锚固体系所造成的影响较小，有利于使防护网能够保持良好的防护能力。
