Embodiment Construction

[0033] A fast and labor-saving safe rescue method, which is realized by the following steps:

[0034] Step S1: Prefabricate the jacking rail 1, the jacking reaction frame, the jacking head, and several sets of supporting segments respectively;

[0035] The jacking reaction frame includes a box-shaped frame 201 and a supporting circular tube 202; the rear end surface of the supporting circular tube 202 is respectively connected to the front side of the left front column, the front side of the right front column, the front side of the front upper beam, and the front lower side of the box-shaped frame 201. The front side of the beam is fixed as one;

[0036] The jacking machine head includes a circular tubular casing 301, a circumferential rib A302, four circumferential ribs B303, a circular sliding seat 304, four hydraulic jacks 305, and a hydraulic pump station 306; The front-end nozzle of the shell 301 is a chamfered nozzle facing forward and downward; the circumferential rib...

Abstract

The present invention relates to landslide rescue technology, specifically a fast and labor-saving safe rescue method, which is realized by the following steps: Step S1: Prefabricate the jacking track, the jacking reaction frame, the jacking head, and several groups of supports respectively. Protective tube; Step S2: Reinforce the collapse body against pressure; Step S3: Hoist and splice the jacking rail, jacking reaction frame, and jacking head; Step S4: Hold the box frame forward, four The hydraulic jacks elongate synchronously; step S5: after completing one jacking stroke, the four hydraulic jacks retract synchronously; step S6: after all the soil is transported out, the four hydraulic jacks elongate synchronously; step S7: after completing one jacking stroke, The four hydraulic jacks are retracted synchronously; step S8: the circular tubular casing pushes through the landslide body forward. It not only greatly improves the rescue efficiency, but also the excavation process is carried out under the protection of the circular tubular casing, which reduces the disturbance to the surrounding soil and has high stability, thus fully ensuring the safety of the rescue process.

Description

technical field [0001] The invention relates to landslide rescue technology, in particular to a quick and labor-saving safe rescue method. Background technique [0002] Landslides are common accidents in tunnel construction and mine operations. Once a landslide accident occurs and people are trapped, how to rescue the trapped people in the shortest time is the primary task of rescue. In order to rescue the trapped people, the domestic rescue method commonly used at present is the small pilot pit rescue method. This kind of rescue method is to excavate a small pilot pit with a rectangular or triangular section in the landslide body, and utilize wooden box frames or hydraulic supports as support to form a method for rescue passages. This method has the following shortcomings: the one is that it takes a long time to When the body is relatively loose, it usually takes 3-4 hours to reach a depth of 1m. When encountering a large rock, use a pick or manual brazing to break it, whi...
