Abstract
The utility model discloses a low earthing corrugated steel and concrete integrated configuration box passageway, the box structure that is formed by the assembly of corrugated steel roof and two curb plates, two curb plates all are higher than the roof vault, set up the horizontal pull rod between the board of both sides, the roof external fixation sets up the vertical ascending shear force piece, and shear force piece and pull rod fixed connection, be equipped with horizontal reinforcing bar net above the pull rod, reinforcing bar net and shear force piece are connected, concrete is poured to cover reinforcing bar net above the roof; the arch height of the top plate can be set to be lower, and the method can be suitable for roads and highways with lower roadbed heights; the top part of the concrete composite structure can be rigid only by paving a thinner pavement layer; the stability of box passageway is improved, and the roof is restricted to the horizontal thrust of both sides by the pull rod, and the curb plate can not expand to both sides, and the curb plate has reduced the reliance to both sides soil body thrust against simultaneously.
Description
Technical Field
The utility model relates to a highway culvert passageway especially relates to a low earthing wave form steel and concrete integrated configuration box passageway.
Background
The assembled corrugated steel box channel is formed by assembling four corrugated steel plates, namely an upper corrugated steel plate, a lower corrugated steel plate, a left corrugated steel plate and a right corrugated steel plate, and is shown in figure 1. The assembled corrugated steel plate box-type channel with the structure has the advantages that the arch height of the top plate is high, the channel is not suitable for roads with low roadbed, but if the arch height of the top plate of the box-type channel is too low, the horizontal pushing force of the side top plate to the arch springing to the two sides is very large, the two side plates can be expanded to the two sides, meanwhile, the internal stress of the top plate can be increased remarkably, and meanwhile, the stability of the structure is reduced remarkably.
Disclosure of Invention
Utility model purpose: the utility model aims at providing a integrated configuration box passageway that is used for low road bed road and stable in structure.
The technical scheme is as follows: the utility model provides a low earthing wave form steel and concrete integrated configuration box passageway, the box structure that forms by the wave form steel roof and two wave form steel curb plates assembly that upwards arch, two curb plates all are higher than the roof vault, set up horizontal pull rod between the both sides board of vault top, the roof external fixation sets up vertical ascending shear force spare, the pull rod top is equipped with the horizontally reinforcing bar net, the reinforcing bar net is connected with shear force spare, the concrete is pour to covering the reinforcing bar net to the roof top.
Further, the shearing force piece is fixedly connected with the pull rod.
Furthermore, the pull rod is attached to the wave trough of the vault of the top plate, the contact area of the pull rod and the top plate is increased, and the height of the poured concrete is reduced.
Further, the shear pieces are steel bars/shear nails.
Furthermore, a wave-shaped flange is fixedly connected to the top plate, a bolt and a corresponding screw hole are formed in the side plate, and the side plate is connected with the wave-shaped flange in a clinging mode through the bolt.
Furthermore, the pull rod penetrates through the two side plates, and a fixing nut is arranged on the outer side of each side plate.
Further, the pull rod is a steel bar or a steel bar.
Furthermore, the box-type structure is also provided with a bottom plate which is a corrugated steel plate or a concrete road.
Further, the side plates are installed on a concrete foundation.
Has the advantages that: compared with the prior art, the utility model has the advantages of as follows: 1. the arch height of the top plate can be set to be lower, so that the method can be suitable for roads and highways with lower roadbed heights; 2. the stability of the box-type channel is improved, the horizontal thrust of the top plate to two sides is limited by the pull rod, the side plates cannot expand to two sides, and meanwhile, the side plates reduce the dependence on the reverse thrust of soil bodies on two sides; 3. the top can ensure normal traffic only by laying a thinner pavement layer.

FIG. 1 is a schematic cross-sectional view of a prior art structure;
fig. 2 is a schematic cross-sectional view of the present invention.
Detailed Description
The technical solution of the present invention will be further explained with reference to the accompanying drawings.
As shown in fig. 2, the low earth-covered corrugated steel and concrete composite structure box-type channel is assembled by a corrugated steel top plate 1 and two side plates 2 which have certain outer arc radians, and the bottom plate can be a concrete road or a steel plate and other materials; the side plates 2 are fixedly arranged on a concrete foundation; the inner sides of the two side plates 2 are fixedly connected with the wave-shaped flanges 6 through bolts respectively, and two ends of the wave-shaped steel top plate 1 are welded and fixed with the two wave-shaped flanges 6 respectively; the heights of the two side plates 2 are higher than the arch height of the top plate 1, the pull rod 3 is transversely tensioned in the wave-shaped wave trough of the top plate 1, two ends of the pull rod 3 respectively penetrate through the wave-shaped flanges 6 on the two sides and are fixed on the outer sides of the two side plates 2 by nuts, and the pull rod 3 can be a steel bar or a steel bar; a plurality of shear pieces 4 are welded and fixed on the top plate 1, the shear pieces 4 can be shear nails or steel bars or a mixture of steel bars and the shear nails, and the shear pieces 4 are fixedly connected with the pull rods 3; a horizontal steel bar mesh 5 is arranged above the pull rod 3 in a clinging manner, and the steel bar mesh 5 is also connected with the shearing piece 4; and after the box-type structure is assembled, pouring concrete on the top end, and stopping pouring when the steel bar net 5 is covered to form the final box-type channel of the low-earth-covered corrugated steel and concrete combined structure.
