Abstract
The utility model relates to a culvert construction device, in particular to a high-strength corrugated culvert pipe which comprises a metal pipe with uniform wall thickness through one-step hydraulic or rolling molding, and the pipe wall of the metal pipe is ring corrugated. The utility model has the advantages of high strength, good flexibility, uniform wall thickness, convenient transportation and simple and fast installation.
Description
Technical field
The utility model relates to a kind of culvert building device.
Background technique
Existing culvert is constructed employed culvert pipe in the process, mostly is concrete reinforced pipe, and this culvert pipe is at the bigger extremely frigid zones of day and night temperature, owing to easy bursting by freezing of the reason of expanding with heat and contract with cold or expansion breakage.And the replacing of culvert pipe and repairing efficiency are long, and the expense height can make a big impact to the traffic of culvert pipe top road simultaneously.In the existing culvert pipe, also have a spot of metal culvert pipe, but all there are more incomplete place in its making method and culvert pipe moulding,, but can't realize using effect preferably so its fabricating cost is higher.
Summary of the invention
The purpose of this utility model is to avoid the deficiencies in the prior art that a kind of high strength is provided, and pliability is good, and wall thickness is even, and convenient transportation is installed simple and direct high strength ripple culvert pipe.
For achieving the above object, the technological scheme that the utility model is taked is: a kind of high strength ripple culvert pipe, include a wall thickness even metal pipe, and the tube wall of described metal tube is the annulus corrugated.
Further, described metal tube is at least two, is connected by connection set between the metal tube in twos.
Further, described metal tube is that hydraulic pressure or roll extrusion are one-body molded.
Another structure characteristic of the ripple culvert pipe of shaped by fluid pressure is that pipe thickness is even, has avoided the damage of existing forming technique for tube wall as far as possible, and this has just guaranteed the high strength and stability of this novel culvert pipe, thereby has increased the working life of culvert pipe.Because this novel employing shaped by fluid pressure technology so the waveform of this novel culvert pipe is natural and tripping, has so just improved the non-deformability of ripple culvert pipe greatly.Existing forming technique generally is the roll extrusion technology, and the raising along with the roll extrusion technology also still can reach technique effect of the present utility model certainly.
Further, described connection set includes flange plate, is provided with packing ring in the flange plate joint.Metal tube utilizes flange plate to achieve a butt joint, and in the docking operation, the tight degree in order to ensure butt joint adds seal washer between joint two flange plate.
Further, described packing ring is asbestos or rubber washer.。
Further, the inner and outer surface of the tube wall of described metal tube is equipped with hot galvanizing anticorrosive coat or pitch anticorrosive coat or both and is provided with simultaneously.
Further, the angle of the line of the intersection point of the crest of the ripple of described metal tube tube wall and ripple center line and ripple and ripple center line formation is about the 15-35 degree.The line that crest that described ripple center line is a ripple and trough mid point are formed.
Further, the internal diameter of described metal tube is generally 0.5m-8m, and the pipe thickness scope is 2.5mm-10mm.
Further, pitch of waves scope is 110mm-200mm, and the wave height scope is 25-70mm.
The beneficial effects of the utility model are: high strength, and pliability is good, and wall thickness is even, and convenient transportation is installed simple and direct.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A portion enlarged view of the utility model Fig. 1;
Fig. 3 is the sectional view of tube wall of the present utility model.
Embodiment
Below in conjunction with accompanying drawing principle of the present utility model and feature are described, institute gives an actual example and only is used to explain the utility model, is not to be used to limit scope of the present utility model.
