Embodiment Construction

[0028] Examples see figure 1 , figure 2 As shown, the rapid rescue method of this tunnel door collapse collapse, its steps are as follows.

[0029] Step 1. Install the spiral excavation pipe jacking and pipe curtain construction equipment with screw excavation function and oil cylinder jacking function at 21 places in the safety zone of the excavated tunnel, and can perform both spiral excavation and oil cylinder jacking operations at the same time. The pipe screen construction equipment consists of a frame, a drilling rig, a drilling tool and a back top, wherein the drilling tool is connected to the drilling rig, the drilling rig is set on the frame, and the tail end of the drilling rig is pushed against the front end of the back top.

[0030] Step 2, use the spiral unearthed pipe jacking pipe curtain construction equipment, at the bottom of the closed door collapse area 20 in the excavated tunnel hole, push the steel pipe that can accommodate at least one person through th...

Abstract

The invention discloses a rapid rescuing method for tunnel gateway collapse. The rapid recuing method comprises the following steps: I, installing spiral excavation pipe-jacking pipe curtain construction equipment provided with a spiral excavation function and an oil cylinder jacking function, and capable of simultaneously performing spiral excavation operation and oil cylinder jacking operation at a safety area in an excavated tunnel hole; II, arranging at least one steel tube capable of passing through a person on the bottom of a gateway collapse area in an the excavated tunnel by virtue of the spiral excavation pipe-jacking pipe curtain construction equipment, introducing the steel through into a construction operation area of the excavated tunnel after passing through the gateway collapse area, and forming an escape channel by the steel tube; III, directing the staff in the construction operation area to escape to the safety area from the escape channel. The invention belongs to a novel-use invention of the known product, the spiral excavation pipe-jacking pipe curtain construction equipment is transferred and applied to a tunnel collapse manual rescuing direction from the tunnel forepoling construction direction, so that the complexity of the tunnel collapse rescue is greatly lowered, and the tunnel collapse rescue speed is increased.

Description

technical field [0001] The invention relates to a method for rescuing construction workers when a tunnel closes and collapses. Background technique [0002] The scale of tunnel construction in my country is huge, and tunnel closures and landslides occur from time to time. The so-called closed door landslide means that when construction workers are working on the face of the tunnel, part of the tunnel that has been constructed behind will collapse and the front construction workers will be trapped inside and unable to leave the dangerous area. This kind of situation generally occurs in the scene where the secondary lining does not keep up in time and the supporting force of the primary lining in the collapsed area is insufficient. When a tunnel closes and collapses, the construction workers are trapped in a narrow dangerous area, and the quick rescue of the trapped people becomes the top priority. [0003] Traditional rescue methods mainly use manual digging of an escape pi...
