Description

High-steep side slope landslide disaster protection emergency rescue method Technical Field The invention relates to a landslide emergency rescue method, in particular to a high-steep side landslide disaster protection emergency rescue method suitable for landslide disasters, and belongs to the technical field of emergency rescue. Background In the scenes such as high and steep side slopes, heavy rainfall, freezing and thawing areas, earthquake influence areas and the like, the side slopes are extremely easy to be unstable and induce landslide due to the superposition influence of rainfall infiltration, earthquake vibration and excavation disturbance. The loose accumulation bodies formed after destabilization are difficult to stabilize in a short period, in the landslide rescue and emergency treatment processes, operations such as obstacle removal, search and rescue, guide and reinforcement and the like must be carried out nearby the unstable slope bodies, mechanical vibration, personnel stepping in, rainfall re-infiltration are all very likely to induce secondary collapse, not only can direct threat to life safety of rescue personnel and disaster-stricken masses, but also limit equipment delivery, channel opening and wounding transportation, and uncertainty and complexity of emergency rescue are greatly increased. The existing slope treatment technology mainly faces to the requirements of normalization and long-term stability and comprises systems such as anchor rods (cables), sprayed concrete, lattice beams, soil nailing walls, anti-slide piles, retaining walls, micro piles, comprehensive drainage and the like. The technology generally depends on detailed investigation design and more complete construction procedures, needs stable working face, complete equipment and long construction period, is difficult to meet the emergency safety requirements of fast-forward, fast-handling and fast-evacuation after disaster, and meanwhile, once a rigid structure is formed, the rigid structure is difficult to adjust and remove, and is not suitable for temporary and maneuverable rescue scenes. Aiming at the temporary slope protection during landslide emergency rescue, the simple structures such as sand bags, steel pipe supports, temporary retaining walls, passive protective nets, and industrial piles are generally adopted, and the common problems that ① is insufficient in adaptability, complex slopes and irregular piles are difficult to attach quickly, ② is low in unitization and modularization degree, low in transportation, hoisting and quick assembly efficiency, ③ is limited in anti-slip, impact and energy consumption performance under the action of rainfall re-infiltration and vibration, ④ is insufficient in cooperation with measures such as drainage, unloading and load reduction, and the overall risk reduction effect is limited. Aiming at the aspects of equipment and personnel transportation during landslide emergency rescue, the method generally adopts modes of manual carrying, rope climbing, temporary stairway, simple cableway (pulley block) and the like, and has the problems of limited traffic capacity, insufficient capacity of crossing dangerous zones, low efficiency, poor safety and the like, and the problem that large machines are difficult to approach to a working surface, so that the ascending and descending transportation of materials and wounded persons is often limited by terrains and secondary disaster risks. For monitoring and early warning during landslide emergency rescue, although the technologies of total station displacement monitoring, inclinometer and crack meter, in-hole inclinometry, rainfall and hole pressure sensing, foundation synthetic aperture radar, microseismic/acoustic emission and the like are widely applied, pain points such as long deployment time, scattered data, difficulty in linkage with site operation and the like exist under emergency conditions, the threshold setting and early warning strategies are mostly general schemes, dynamic self-adaption is difficult to carry out according to unloading, reinforcement and rainfall changes in the treatment process, and a closed loop of 'monitoring, evaluation, treatment and reevaluation' is difficult to form. Comprehensively, the prior art lacks system coordination among three key links of temporary slope protection, personnel transportation of equipment and real-time monitoring and early warning, namely, the slope protection system and a transportation path are mutually restricted, a monitoring system and an operation flow are cracked, energy and communication guarantee are dispersed, so that the rescue efficiency and the operation safety are difficult to be simultaneously considered, and secondary disaster risks such as secondary collapse are difficult to be timely perceived and actively managed and controlled. Disclosure of Invention Aiming at the problems in the prior art, the invention provides the high-steep side slope landslide haza
