prefabricated concrete double-layer corrugated plate structure, arch culvert and pipe culvert
The invention relates to the technical field of corrugated plates, and provides a prefabricated concrete double-layer corrugated plate structure, an arch culvert and a pipe culvert.The prefabricated concrete double-layer corrugated plate structure is characterized in that an arc-shaped outer-layer steel corrugated plate is arranged on one side of an arc-shaped inner-layer steel corrugated plate, and a cavity is formed between the arc-shaped outer-layer steel corrugated plate and the arc-shaped inner-layer steel corrugated plate; the transverse convex flange plate and the transverse concave flange plate are oppositely arranged on the two sides of the cavity, and the transverse convex flange plate is provided with a convex part; a die cavity is defined by the arc-shaped outer-layer steel corrugated plate, the arc-shaped inner-layer steel corrugated plate, the transverse convex flange plate and the transverse concave flange plate, a groove is formed in the transverse concave flange plate, and the convex part is matched with the groove; the arc-shaped steel bar frame is arranged in the die cavity; the outer-layer shear nails and the inner-layer shear nails are arranged on the arc-shaped steel bar frame; the concrete layer is arranged in the die cavity and surrounds the arc-shaped steel bar frame, the outer-layer shear nails and the inner-layer shear nails. According to the technical scheme, the problem that the metal steel corrugated pipe deforms or collapses under the condition of large span or high filling in the prior art is solved.
本发明涉及波纹板技术领域，提出了一种预制混凝土双层波纹板结构、一种拱涵及一种管涵，包括，弧形外层钢波纹板设置在弧形内层钢波纹板一侧，二者之间形成腔体；横向凸型法兰板和横向凹型法兰板相对设置在腔体两侧，横向凸型法兰板上具有凸部；弧形外层钢波纹板、弧形内层钢波纹板、横向凸型法兰板和横向凹型法兰板之间围成模腔，横向凹型法兰板上具有凹槽，凸部与凹槽相配合；弧形钢筋架设置在模腔内；外层剪力钉、内层剪力钉设置在弧形钢筋架上；混凝土层设置在模腔内，将弧形钢筋架、外层剪力钉和内层剪力钉包围。通过上述技术方案，解决了相关技术中大跨径或高填土情况下，金属钢波纹管变形或垮塌的问题。
