Abstract
The invention relates to a multi-layer sleeve rescuing system for tunnel project collapse and an implementation method of the multi-layer sleeve rescuing system. Soil texture and sandy tunnels are poor in surrounding rock and prone to collapse in the construction process, a traditional rescuing mode is generally that a rescuer uses wood supports on a tunnel face for forming a firm tripod structure and rapidly excavating a rescuing channel, so that time is consumed, and construction safety can not be guaranteed. The multi-layer sleeve rescuing system comprises a multi-layer sleeve longitudinally arranged in a collapse body along a tunnel, the sleeve comprises a large-caliber steel pipe, a medium-caliber steel pipe and a small-caliber steel pipe in sequence from outside to inside, an emergency conveying pipe is arranged in the collapse body on one side of the multi-layer sleeve and is in parallel with the multi-layer sleeve, and multiple prospect holes are formed in the circumferential direction of the multi-layer sleeve and are in parallel with the multi-layer sleeve penetrating through the collapse body, the rescuing channel is broken through within the shortest time, and a trapped person climbs out with the help of a rescuing rope to be out of danger. The targeted multi-layer sleeve is selected and used for the soil texture and sandy tunnels for performing collapse rescuing, rescuing time is effectively shortened, and new collapse accidents are effectively prevented from occurring under the disturbance of rescuing construction.
Description
Technical field
the present invention relates to a kind of construction of tunnel rescue aid that caves in, be specifically related to multilayer sleeve rescue system and implementation method thereof that a kind of construction of tunnel is caved in.
Background technology
Soil property and sandy tunnel country rock are poor, very easily cave in, and earth tunnel are different from rock matter tunnel when construction, the body that collapses after landslide is closely knit shape and piles up, tight exists, and outside air can not enter face by the body space of collapsing, and very easily causes face anoxic and causes trapped personnel to suffocate and die.Meanwhile, after Tunnel Landslide, landslide section is extremely unstable, may produce at any time new landslide.In order to guarantee the safety of rescue, reduce to greatest extent the stranded time of trapped personnel, need the rescue of carrying out of maximal rate safety.Tradition rescue mode is generally rescue personnel and utilizes wood to support at face, forms firm tripod structure, Rapid Excavation rescue passage; Or again excavate rescue passage at tunnel skin, but effect is not clearly, and consuming time and working security can not guarantee.
Summary of the invention
The object of this invention is to provide multilayer sleeve rescue system and implementation method thereof that a kind of construction of tunnel is caved in, can effectively improve rescue speed, prevent new landslide.
The technical solution adopted in the present invention is:
The multilayer sleeve rescue system that construction of tunnel is caved in, is characterized in that:
System includes and is longitudinally arranged at the multilayer sleeve collapsing in body along tunnel, from being followed successively by outside to inside large-diameter steel pipe, medium caliber steel pipe and small-caliber steel pipe, multilayer sleeve one side is collapsed in body and is provided with the emergent carrier pipe that is parallel to multilayer sleeve, is provided with some inspecting holes that are parallel to multilayer sleeve multilayer sleeve ring week.
Described multilayer sleeve is placed on the sleeve pipe platform of the body bottom setting of collapsing.
The implementation method of the multilayer sleeve rescue system that construction of tunnel is caved in, is characterized in that:
Realized by following steps:
Step 1: longitudinally perform the emergent carrier pipe of the body inside of collapsing along tunnel, emergency communication, food etc. are sent into and collapsed in body, determine by emergent carrier pipe the volume morphing that collapses simultaneously, to determine the length of rescue passage;
Step 2: longitudinally perform 3-5 root inspecting hole in the body inside of collapsing along tunnel, determine the locus of rescue passage;
Step 3: in the body bottom of collapsing, sleeve pipe platform is set, utilizes site operation machinery longitudinally to head into the large-diameter steel pipe that diameter is 70-80cm along tunnel, artificial muck removal while often heading into 2m;
Step 4: utilize the large-diameter steel pipe heading in advance as construction passage, the mode that adopts machinery progressively to head in large-diameter steel pipe is inserted medium caliber steel pipe and small-caliber steel pipe successively, composition multilayer sleeve, small-caliber steel pipe and large-diameter steel pipe diameter differ 5-10cm;
Step 5: multilayer sleeve, through collapsing body, is got through rescue passage, and trapped personnel climbs out of along steel pipe successively by rope, safe escape.
The present invention has the following advantages:
The present invention selects targetedly the multilayer sleeve rescue of caving in soil property and Support System in Soft Rock Tunnels, effectively shorten the time of rescue, guarantee rescue safety, meet rescue requirement, construction speed is fast, safe, can the very first time get through life passage, be applicable to soil property and weak surrounding rock landslide rescue, under rescue construction disturbance, effectively prevent the generation of new cave in accident.
