Background
With the development of domestic capital construction, China has achieved outstanding performance in the field of building construction.
The section steel concrete composite structure is an independent structural type of embedding section steel into reinforced concrete; because the section steel is added in the reinforced concrete, the section steel has inherent strength and ductility; the section steel, the steel bar and the concrete work integrally, so that the section steel concrete structure has the advantages of large bearing capacity, large rigidity and good earthquake resistance compared with the traditional reinforced concrete structure; compared with a steel structure, the fireproof steel structure has the advantages of good fireproof performance, good stability of the local part and the whole structure and steel saving; at present, steel reinforced concrete structures are mostly adopted for some large buildings or building structures with large span.
In the tunnel construction process, collapse easily occurs due to instability of the rock stratum or the soil layer, so that safety of workers is endangered, and therefore a supporting structure for the rock stratum or the soil layer is evolved in the tunnel excavation process; because the section steel concrete composite structure saves steel, has large bearing capacity, large rigidity, good anti-seismic performance, good fireproof performance and good local and overall stability of the structure, the section steel concrete composite structure adopted in the tunnel to support the rock stratum or the soil layer in the tunnel is superior to the reinforced concrete support; because the influence in arc space in the tunnel, complete shaped steel concrete integrated configuration installs the difficulty in the tunnel, and radian and length can't be held, so at present mostly at the external split, splice in transporting the tunnel again.
The installation method of the section steel concrete composite structure comprises the steps of erecting section steel, supporting a rock stratum or a soil layer above a tunnel by utilizing the section steel in the early stage, and wrapping the section steel by using concrete; after the tunnel is excavated, concrete pouring is carried out only after the section steel arch frame is erected for a period of time; shaped steel bow member mainly leans on support frame and stock to support before concrete placement, but shaped steel can not be paved the inner wall in whole tunnel, along with the excavation in tunnel, because falling rocks or piece influence staff of work in the tunnel can appear at the reason tunnel top of vibrations, and great falling rocks more directly influences staff's life safety.
Disclosure of Invention
The invention aims to solve the technical problem that falling rocks or fragments fall to influence the work and life safety of workers because a steel arch structure cannot fully cover the inner wall of a tunnel in the current steel concrete building process.
