Abstract
The utility model relates to a culvert top wall waterproof composite board. The culvert top wall waterproof composite board is characterized by being formed by sequentially compositing an anti-corrosion board (1), a magnesium oxide glass fiber board (2), an EVA board (3) and a non-woven fabric layer (4) from top to bottom. The thickness of the EVA board (4) is ranges from 0.5mm to 1.5mm. According to the culvert top wall waterproof composite board, the magnesium oxide glass fiber board, the anti-corrosion board and the non-woven fabric layer are composited on the surface of the EVA board, the good waterproof performance is achieved, strength is greatly improved, the performance of the composite board can be well guaranteed even when the composite board is located in the dank environment for a long time due to the anti-corrosion board, the service life is long, and the safety performance is high.
Description
Technical field
The utility model relates to a kind of splash guard, relates in particular to a kind of culvert roof waterproof composite board.Belong to the water conservancy technical field of civil engineering.
Background technology
In the work progresss such as tunnel, subway, need to carry out waterproofing work to roof, when it needs good water resistance, also need higher intensity, existing most processing method is to adopt the EVA(ethylene-vinyl acetate copolymer) plate carries out waterproof, and this kind of splash guard can play the well anti-buffer action that blends, but, its intensity is low, and easy fracture is difficult to meet the roof waterproof demands such as tunnel, subway.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and the culvert roof waterproof composite board that a kind of intensity is high is provided.
The purpose of this utility model is achieved in that a kind of culvert roof waterproof composite board, it is composited from top to bottom successively by anticorrosive board, magnesia glass fiberboard, EVA plate and nonwoven layer, the thickness of described EVA plate is 0.5 ~ 1.5mm, and described anticorrosive board is pitch and PE blend anticorrosive board.
Described nonwoven layer is the terylene needle punched non-woven fabrics.
Compared with prior art, the beneficial effects of the utility model are:
The utility model culvert roof waterproof composite board, in EVA plate surface recombination magnesia glass fiberboard, anticorrosive board and nonwoven layer, when playing good water resistance, increased greatly intensity, due to the existence of anticorrosive board, even long-term under dark and damp environment, also can well guarantee its performance, long service life, security performance is high.
The accompanying drawing explanation
The section structure schematic diagram that Fig. 1 is the utility model culvert roof waterproof composite board.
Wherein:
1-anticorrosive board
2-magnesia glass fiberboard
3-EVA plate
4-nonwoven layer.
The specific embodiment
Referring to Fig. 1, a kind of culvert roof waterproof composite board that the utility model relates to, it is composited from top to bottom successively by anticorrosive board 1, magnesia glass fiberboard 2, EVA plate 3 and nonwoven layer 4, and the thickness of described EVA plate 3 is 0.5 ~ 1.5mm.
Described nonwoven layer 4 is the terylene needle punched non-woven fabrics.
Described anticorrosive board 1 is pitch and PE blend anticorrosive board.
During use, coordinate geotextiles to use, effect is particularly remarkable.
