The utility model discloses utilize the hoop stiffening rib to consolidate the tip of corrugated steel culvert pipe, not only can increase the mechanical strength of corrugated steel culvert pipe tip, because hoop stiffening rib and annex bury the headwall moreover for corrugated steel culvert pipe combines more firmly with the headwall, and bulk strength improves by a wide margin, has just so effectively prevented the emergence of headwall fracture phenomenon, has improved engineering quality greatly.
Description
Technical Field
The utility model relates to a corrugated steel culvert pipe of high strength can effectively prevent culvert, tunnel, underpass, underground piping's headwall fracture, belongs to underground or underwater structure technical field.
Background
The corrugated steel plate is a novel building material, has good ductility and strong anti-deformation capability, and also has the advantages of quick and convenient installation, short construction period, low processing cost, environmental protection and the like. At present, corrugated steel plates are widely used in traffic engineering and municipal engineering to manufacture engineering components such as culverts, tunnels, underground passages, underground pipelines and the like. However, after the pipe diameter exceeds 2 meters, the end part of the traditional corrugated steel culvert has the phenomenon of strength weakening, which easily causes end wall cracking, thereby seriously affecting the engineering quality, and therefore, the existing corrugated steel culvert needs to be improved.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a high strength corrugated steel culvert pipe to the drawback of prior art to improve the mechanical strength of culvert pipe tip, guarantee the engineering quality.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the high-strength corrugated steel culvert pipe comprises a corrugated steel culvert pipe body and a circumferential reinforcing rib arranged at the end part of the corrugated steel culvert pipe body, wherein the circumferential reinforcing rib is attached to the outer side of the corrugated steel culvert pipe body and is fixedly connected with the corrugated steel culvert pipe body.
In the high-strength corrugated steel culvert pipe, the circumferential reinforcing ribs are 360-degree circumferential ribs or arc ribs less than 360 degrees, which are attached to the outer side of the corrugated steel culvert pipe body.
In the high-strength corrugated steel culvert pipe, the annular reinforcing ribs are corrugated steel plates attached to the outer side of the corrugated steel culvert pipe body.
In the high-strength corrugated steel culvert pipe, L-type bolts embedded into the end wall are arranged on the corrugated steel plate, and the L-type bolts are directly fixed on the corrugated steel plate or connected with the corrugated steel plate through the connecting plate.
In the high-strength corrugated steel culvert pipe, the annular reinforcing ribs are the section steel embedded in the end wall.
Above-mentioned high strength corrugated steel culvert pipe, shaped steel sets up two at least, and they are arranged along the length direction of corrugated steel culvert pipe body, is connected through the connection dead lever of burying the headwall between the adjacent shaped steel.
The utility model discloses utilize the hoop stiffening rib to consolidate the tip of corrugated steel culvert pipe, not only can increase the mechanical strength of corrugated steel culvert pipe tip, because hoop stiffening rib and annex bury the headwall moreover for corrugated steel culvert pipe combines more firmly with the headwall, and bulk strength improves by a wide margin, has just so effectively prevented the emergence of headwall fracture phenomenon, has improved engineering quality greatly.
Drawings
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
FIG. 1 is a schematic structural view of the present invention when the circumferential stiffener is a corrugated steel plate;
fig. 2 is a schematic structural view of the present invention when the circumferential reinforcing rib is a section steel (angle steel).
The reference numbers in the figure are 1, a corrugated steel culvert body, 2, circumferential reinforcing ribs, 3, L type bolts, 4, a connecting plate, 5, a connecting fixing rod, 6 and an end wall.
Detailed Description
The utility model provides a high strength corrugated steel culvert pipe, the tip outside of this kind of corrugated steel culvert pipe is equipped with the hoop stiffening rib, and the hoop stiffening rib can increase the structural strength of corrugated steel culvert pipe tip, avoids the corrugated steel culvert pipe to take place to warp because of the tip and causes the headwall fracture.
The circumferential reinforcing rib can be a corrugated steel plate or a section steel. In the circumferential direction of the corrugated steel culvert body 1, the circumferential reinforcing ribs can be 360-degree annular ribs, can also be arc-shaped ribs within the range of 180-270 degrees, and can also be arc-shaped ribs arranged on weak positions.
The hoop reinforcement rib 2 in figure 1 adopts a corrugated steel plate, the width of the corrugated steel plate is determined according to the parameters such as the diameter of the corrugated steel culvert body 1, the corrugated steel plate is connected with the corrugated steel culvert body 1 through bolts, in order to further improve the strength of the corrugated steel culvert, a plurality of L-type bolts 3 can be arranged on the corrugated steel plate, each L-type bolt 3 is fixed on the corrugated steel plate through a nut, or the L-type bolt 3 is fixed on a connecting plate 4 firstly, and then the connecting plate 4 is welded on the corrugated steel plate, the L-type bolt 3 and the corrugated steel plate are embedded into an end wall together, so that the corrugated steel culvert body 1 and the end wall are combined more firmly, the overall strength is higher, and the structure well solves the problem of the weak strength of the end part of the corrugated pipe.
The circumferential reinforcing rib 2 in fig. 2 is made of section steel, the section steel in the drawing is angle steel, and other section steels such as T-shaped steel, H-shaped steel, i-shaped steel and the like can be adopted in specific implementation. Shape and corrugated steel culvert pipe body 1 phase-match behind the shaped steel arc, utilize the bolt to link together shaped steel and corrugated steel culvert pipe body 1, shaped steel can set up one, also can set up two or more, a plurality of shaped steel are arranged along corrugated steel culvert pipe body 1's length direction, when setting up two or more shaped steel, connect through connecting dead lever 5 between the adjacent shaped steel, shaped steel all buries the headwall with connecting dead lever 5, become a whole with the headwall, the stability of structure has effectively been strengthened.
