1, it radiates convenient for the cable in underdrain；
2, after multiple trench cover splicings, repair and maintenance is carried out convenient for opening trench cover by the sunk structure；
If 3, meeting rainy weather, which can also be used in rainwater and flows into ditch.
Preferably, when the cover sheet thickness be 5-6cm when, further include reinforcing bar, the reinforcing bar along the cover board length and/
Or width direction is set in the cover board.And when the thickness of cover board is smaller, such as 3-4cm, then no setting is required in cover board reinforcing bar,
In general, the cover board of 5-6cm can be used for the gutter of highway, and the cover board of 3-4cm can be used for tunnel side ditch.
Preferably, the steel-bar arrangement is at operculum colpi plate thickness direction side 1-1.5cm.The sunk structure
The angle of broadside and bevel edge is 130-135 °.
Beneficial effect by adopting the above technical scheme is: passing through the reasonable position setting of reinforcing bar and sunk structure angle
Optimum choice effectively improves the intensity and durability of cover board entirety, substantially increases the service life of cover board.
