Description
Technical field
The invention belongs to traffic city planting ductwork apparatus fields, and in particular to a kind of trench water drainage cover board, which are mainly applied to
Enterprise's different kinds of roads, ditch, the place for especially having loaded vehicle to cross are also applied to the various traffic links such as highway, street and municipal administration
The place needed.
Background technique
Sewer cover plate or trench water drainage cover board are much using link, are having stronger static pressure and impact force.Such as
On highway, when the vehicle of fair speed rolls up, impact force is the vehicle hydrostatic power of several times.Inspection well cover and trench row
The damage of water cover plate, 90% or more be cover board anti-shear ability can not overcome impact bring shearing force and damage (Fig. 1).It passes
The method of system be thicken its structure, but it is too thick after, not only consume a large amount of material, there is also difficulties for installation.It is built some
The place that component uses is built, the problems such as there is also the permissions of load.It is public to be responsible for factory for especially factories and miness unit communal facility department
The maintenance of facility, the breakage of trench water drainage cover board often bring hidden danger to the personal safety of employee altogether.
Summary of the invention
For above one or more technical problems, a kind of section arc trench water drainage cover board and mold are provided.
The principle of the present invention are as follows:
Using the principle of mechanics and structure, when external force is on the object of different structure, force resolution is different
: two end faces of traditional trench water drainage cover board be it is parallel, act on power above and the thickness of material all leaned on to be formed
Anti-shearing force overcomes (see Fig. 1)；Trench water drainage cover board of the invention, end face be it is arc-shaped, act on power above, only
A part overcomes by the shearing force that the thickness of material is formed, and direction other then along circular arc is to the edge of trench water drainage cover board
Diffusion, this part power are that the intensity of material and anti-pressure ability is leaned on to absorb, the anti-shearing force formed by the thickness of material and material,
Need smaller (see Fig. 2)；Therefore the damage of trench water drainage cover board is just drastically reduced.
The one side of technical solution of the present invention provides a kind of section trench containing arc water drainage cover board comprising ontology, more
A drainage hole, the ontology include first end face, second end face, first side, second side；
The first end face and/or the second end face are arc, and the first end face and the second end face are uneven
Row, the shape in the section of the ontology includes at least one arc-shaped side；

Further, the first end face and the second end face are arc；The middle section of the second end face is
Segmental arc, segmental arc two sides are horizontal segment.
Further, the first end face and the second end face are arc；The middle section of the second end face is
First segmental arc, segmental arc two sides are the second segmental arc, and the radius of the first segmental arc is greater than the second segmental arc；The first end face
Third segmental arc is formed, the radius of third segmental arc is less than the first segmental arc.
Further, the cross sectional shape of the ontology is arch bridge shape.
Further, the second end face is arc；The middle section of the second end face is the first segmental arc, segmental arc
Two sides are the second segmental arc, and the radius of the first segmental arc is greater than the second segmental arc.
Further, the second end face is arc；The middle section of the second end face is segmental arc, segmental arc two sides
For horizontal segment.
Further, the horizontal projection shape of the ontology is cuboid, and the drainage hole is strip hole, the drainage hole
It is evenly distributed on the body.
Further, the drainage hole is two rows of uniformly distributed arrangements.
Further, the ontology uses cast iron or precast reinforced concrete.
Another aspect of the present invention provides a kind of mold, adopts a split structure, including upper die and lower die, its is recessed for upper mold
If the shape in portion and the upper half of the above-mentioned section water drainage cover board of trench containing arc match, the shape of its projection portion of lower die with it is upper
The lower half for the section water drainage cover board of trench containing arc stated matches.
