Abstract
An internal supporting structure of bridges, culverts and tunnels belongs to the technical field of road, bridge and culvert facilities and is used for internally supporting passages, negative wells, urban utility tunnels and drainage facilities in projects including highways, municipal administrations and railways. The technical scheme is that the internal supporting structure is of a pipe-shaped structure with two ends opened, the wall of a pipe body is corrugated, the cross section of the pipe wall is round, arch-shaped or oval, and the height and the span of the pipe wall are matched with those of the construction bridges, culverts and tunnels. The wall of the pipe body is formed by respectively connecting a plurality of bent corrugated plates along the circumference and the axial direction of a pipeline, circumferential joint positions of left corrugated plates and right corrugated plates which are adjacent to each other are vertically overlapped, and pipeline axial joint positions of front corrugated plates and rear corrugated plates which are adjacent to each other are all provided with flanging bent for 90 degrees and connected through fastening bolts. The internal supporting structure can adopt factory standardization processing, has the advantages of being light in weight, high in strength, fast in construction and convenient to construct, occupies only 1/3 of construction time of concrete structures, and can save about 20% of manufacture price.
Description
Technical field
The utility model relates to the inner supporting structure of passage, negative well, city common trench and drainage in the engineerings such as a kind of highway, municipal administration, railway, belongs to road bridges and culverts facility technology field.
Background technology
In the buried structure of highway constructions such as highway, municipal administration, in the building of engineerings such as the reinforcing of old bridges and culverts, city common trench, highway tunnel, negative well, coal mine roadway, owing to outsidely not have an operating surface of constructing; Often need carry out construction internally, adopt conventional concrete structure construction difficulty big, not easy to operate; Construction period is long; And the construction costs expense is high, and the fast-developing needs of modern project that are far from suitable are necessary to improve at aspects such as new material, new technologies.
The utility model content
The utility model technical problem to be solved provide a kind of can be big in span, the job site realize in the narrow space very much construction simply, bridges and culverts, tunnel inner supporting structure efficiently.
The technical scheme that solves the problems of the technologies described above is:
A kind of bridges and culverts, tunnel inner supporting structure, it is a kind of tubular structure of both ends open, tube body wall is a corrugated, the cross section of body is circular, arch or ellipse, the height of body with stride the footpath and be complementary with construction bridges and culverts, tunnel.
Above-mentioned bridges and culverts, tunnel inner supporting structure, said tube body wall is connected to form by the crooked corrugated sheet of polylith, and the polylith corrugated sheet interconnects along circumference and pipeline axial respectively; The circumferential seam crossing of two corrugated sheets that the left and right sides is adjacent overlaps up and down; Corresponding screw is arranged on the plate face of overlap joint, be installed with fastening bolt in the screw, the pipeline axial seam crossing of two corrugated sheets that front and back are adjacent all has the flange of bending 90o; Corresponding screw is arranged on the flange, be installed with fastening bolt in the screw.
Above-mentioned bridges and culverts, tunnel inner supporting structure, said body to stride the footpath be 4000～18000mm, the corrugated sheet that constitutes tube body wall is a steel material, the steel plate thickness of slab is 2.5---8mm, the pitch of waves is that 100-400mm, the depth of convolution are 25-150mm.
Above-mentioned bridges and culverts, tunnel inner supporting structure, said corrugated sheet steel plate thickness of slab are that 5.0mm, the pitch of waves are that 150mm, the depth of convolution are 50mm.
The tube wall of the utility model is designed to corrugated; Section is rounded, arch or ellipse, and it strides the footpath can accomplish 4 meters-18 meters, can adopt factory normalization processing; Have in light weight; The advantage that intensity is high, speed of application is fast, be convenient to construct is 1/3rd of concrete structure on the engineering time, can save about 20% on the cost.
