Abstract
The utility model discloses a supporting structure of a corrosion and collapse tunnel section. The supporting structure comprises I-beams, the corrosion or collapse tunnel section, sleepers, steel tubes and feet-lock bolts. The corrosion or collapse tunnel section is provided with a permanent concrete lining structure body, a corrosion or collapse cavity is formed above the permanent concrete lining structure body, the I-beams are evenly distributed in the permanent concrete lining structure body and are firmly welded to the feet-lock bolts, the sleepers are arranged on the tops of the I-beams, and the steel tubas are arranged in the corrosion or collapse cavity. The supporting structure has the advantages that construction quality of temporary supporting and safety of constructors are guaranteed in the tunnel construction period, meanwhile, the steel rib binding construction procedure is simplified, the construction process of the concrete lining structure body is accelerated, and project investment is saved.
Description
Technical field
The utility model relates to a kind of supporting and protection structure for corrosion and landslide hole section, belongs to tunnel support technical field.
Background technology
At present, according to tunnel excavation supporting quality, control feature, when running into corrosion, landslide hole section, generally take to manage canopy or Simple wood support carries out temporary lining processing, after Tunnel excavation completes, again corrosion, landslide hole section are carried out to permanent concrete lining.Because the rigidity such as pipe canopy and Simple wood support are lower; globality is poor; can not effectively tackle corrosion, the piece stone that falls down of landslide section top, hole, and easily by piece stone pound distortion and and lose construction period safeguard protection effect, bring potential safety hazard to engineering construction phase constructor's person.And after pipe canopy and timbering are pounded distortion, occupied concrete lining structure section, can not guarantee concrete lining architecture quality, brought potential safety hazard to the permanent operation of engineering.Facts have proved, adopt in the situation of as above this construction technology, construction period temporary lining measure is not ideal enough, and construction period constructor personal safety exists hidden danger; In addition, because structure section size is occupied, permanent concrete lining structure workmanship can not get guarantee, and the permanent operation of engineering exists potential safety hazard.
Summary of the invention
The purpose of this utility model is to provide a kind of supporting and protection structure for corrosion and landslide hole section, can overcome the deficiencies in the prior art, can simplify reinforcing bar binding working procedure, accelerate concrete lining structure construction speed, save construction investment, ensure construction quality and constructor's safety of supporting simultaneously.
The purpose of this utility model is achieved through the following technical solutions: a kind of supporting and protection structure for corrosion and landslide hole section, it comprises i iron, corrosion or landslide hole section, sleeper, steel pipe and lock foot anchoring stock, in corrosion or landslide hole section, be provided with permanent concrete lining structure, the top of permanent concrete lining structure is corrosion or landslide cavity, i iron be evenly arranged in permanent concrete lining structure and and lock foot anchoring stock firm welding, sleeper is set up the top at i iron, and steel pipe is placed in corrosion or landslide cavity.
In described permanent concrete lining structure, be provided with principal rod.
The beneficial effects of the utility model are: the i iron of employing not only rigidity and toughness high, and with sleeper, pea gravel concreten forms integral body in good condition, can effectively cushion corrosion, the impulse force of piece stone is fallen down at landslide section top, hole, the construction quality of tunnel construction phase temporary lining and constructor have obtained safely guarantee, simultaneously due to i iron and sleeper, pea gravel concreten forms rigid body, can do not pounded distortion by piece stone, can not occupy permanent concrete lining structure section, and i iron can be used as primary structure member and substitutes the corresponding site reinforcing bar in permanent concrete lining structure, simplified reinforcing bar binding working procedure, accelerated concrete lining structure construction speed, saved construction investment.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the sectional view of the utility model i iron;
Fig. 3 is the sectional view of the utility model sleeper;
Fig. 4 is the sectional view of the permanent concrete lining structure of the utility model.
Wherein, 1-i iron, 2-corrosion or landslide hole section, 3-sleeper, 4-corrosion or landslide cavity, 5-pea gravel concreten, 6-steel pipe, the permanent concrete lining structure of 7-, 8-principal rod, 9-lock foot anchoring stock.
The specific embodiment
Below in conjunction with accompanying drawing, further describe the technical solution of the utility model, but described in claimed scope is not limited to.
Fig. 3 as shown in Figure 1, Figure 2,, a kind of supporting and protection structure for corrosion and landslide hole section, it comprises i iron 1, corrosion or landslide hole section 2, sleeper 3, steel pipe 6 and lock foot anchoring stock 9, in corrosion or landslide hole section 2, be provided with permanent concrete lining structure 7, the top of permanent concrete lining structure 7 is corrosion or landslide cavity 4, i iron 1 be evenly arranged in permanent concrete lining structure 7 and and lock foot anchoring stock 9 firm welding, sleeper 3 is set up at the top of i iron 1, and steel pipe 6 is placed in corrosion or landslide cavity 4.
As Fig. 4, in described permanent concrete lining structure 7, be provided with principal rod 8.
Pea gravel concreten 5 is inputed in corrosion or landslide cavity 4 by steel pipe 6, when permanent concrete lining structure 7 pouring construction, i iron 1 can be used as the steel bar stress 8 that primary structure member substitutes corresponding site, because i iron is set up in employing, lay railway sleepers and build pea gravel concreten, construction technology is convenient, feasible, and safe and reliable, i iron, sleeper and pea gravel concreten form rigid body, difficult quilt is pounded distortion, can not occupy permanent concrete lining structure section, guarantee concrete lining structure quality, i iron can be used as primary structure member and substitutes the corresponding site steel bar stress in permanent concrete lining structure simultaneously, simplified reinforcing bar binding working procedure, accelerated concrete lining structure construction speed, saved construction investment.
