Accompanying drawing explanation
Fig. 1 is the cell board structural representation of the nonmetal high-strength sound barrier of high ferro embankment in this utility model one embodiment.
Fig. 2 is a cross section view of Fig. 1.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out clear,
Complete description.
In one embodiment, it is provided that a kind of nonmetal high-strength sound barrier of high ferro embankment, including: be positioned at embankment one or both sides
Many support posts；Multiple cell boards of stacking it are provided with between adjacent two support posts of homonymy；As shown in Figures 1 and 2,
Cell board includes: have internal cavities one closed shell, and the material of this closed shell is concrete, and it includes head and the tail successively
Upper head plate 3, panel 1, bottom plate 4 and the backboard 2 connected；Internal cavities is filled with an absorbent treatment (not shown)；Absorbent treatment
Including being positioned at a rock cotton board of panel 1 side, it is positioned at a grain plastic plate of backboard 2 side, and is positioned at rock cotton board and panel
A glass film between 1.
Overall dimensions according to practice of construction situation cell board is chosen as: length 1960 to 3960 millimeters, highly 430 to 500
Millimeter, thick 120 to 140 millimeters.
Wherein, the thickness of panel 1 is chosen as 35 to 40 millimeters.Offering uniform multiple elongated holes on panel 1, punching rate is
25%.The thickness of backboard 2 is chosen as 30 to 35 millimeters.The thickness of upper head plate 3 and bottom plate 4 is 35 to 40 millimeters.
It addition, upper head plate 3 and bottom plate 4 are respectively formed with the convex beam isometric with cell board, groove.So that it is neighbouring
Stable fastening between two cell boards.On this basis, a sealing gasket also it is equipped with between neighbouring cell board.
