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 invention relates to a collapse rescue technology, in particular to a quick and labor-saving safe rescue method which is realized by adopting the following steps: S1, a jacking track, a jacking reaction frame, a jacking machine head and a plurality of groups of supporting segments are respectively prefabricated; S2, the collapse body is subjected to back pressure reinforcement; S3, the jacking track, the jacking reaction frame and the jacking machine head are hoisted and spliced; S4, the box-shaped frame is propped forwards, and the four hydraulic jacks extend synchronously; S5, after one jacking stroke is completed, the four hydraulic jacks retract synchronously; S6, after all the soil bodies are transported out, the four hydraulic jacks stretch synchronously; S7, after one jacking stroke is completed, the four hydraulic jacks retract synchronously; and S8, the circular-tube-shaped machine shell forwards penetrates through the collapse body in a jacking mode. The rescue efficiency is greatly improved, the excavation process is carried out under the protection of the circular-tube-shaped machine shell, disturbance to surrounding soil is reduced, the stability performance is high, and therefore the safety of the rescue process is fully guaranteed.

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...
