ditch cover plate is also known as "gutter cover" and "manhole cover". At first, the "manhole cover" was made of cement and cast iron, but it was easy to be damaged in normal use and the replacement cost was high. It is made of steel grating plate by pressure welding, which has the advantages of simple construction and installation, light weight, good bearing capacity, strong impact resistance, non-slip and excellent drainage. Then, next, Xiaobian introduces the use of ditch cover plate and the types of ditch cover plate.
uses of ditch cover plate
1. water treatment: maintenance of walkways, sewer covers, cleaners, trash racks, running water tanks, hangers for biochemical water treatment tanks, ventilation window, stairs, and pavements for cooling tower operation desks.
2. Chemical plant: stair treads, operating platforms, guardrails, double floors, gutter covers and grids.
3. Petroleum industry: offshore oil platforms.
4. Power plant: cover plate of gutter in chemical water workshop, waste water pool, etc.
ditch cover plate type
1 and XU type ditch cover plate
are suitable for most common concrete ditches without kerbs. The U-shaped trench cover is very simple and economical, and no special kerbs are needed. When the loads are T-6 and T-14, it is recommended to bury angle steel in the ditch. When passing cars is needed, this type of ditch cover is only suitable for side ditches (the direction of traffic is parallel to the direction of the ditch). It is suitable for most common concrete ditches with no edge opening. It is very simple and economical to adopt U-shaped ditch cover, and no special edge opening is needed. When the load is T-6 and T-14, it is suggested to bury angle steel in the ditch. When passing cars is needed, this type of ditch cover is only suitable for side ditches (the direction of traffic is parallel to the direction of the ditch). Code description:
2. XT-type ditch cover plate
is suitable for ditches with bearing kerbs, which are usually protected by angle steel. When it is used as a transverse ditch cover (the direction of the vehicle is perpendicular to the direction of the ditch), considering the danger of the cover plate being provoked by impact, the ditch cover should be bolted or welded on the angle steel masonry, and the steel grid ditch cover should be hot-dipped galvanized for corrosion protection.
3. XM-type covers for water supply and drainage wells, air holes, manholes, etc. of municipal facilities such as roads and parks in ditch cover plate
can be used.
4. XG ditch cover plate
is suitable for the deep trench along the bearing. When it is used side by side with the concrete well cover plate, it can be flush with the upper surface of concrete ditch cover plate; When it is used as a transverse ditch cover (the direction of the vehicle is perpendicular to the direction of the ditch cover), it can effectively prevent the cover from being provoked by impact. Hot dip zinc is used for corrosion protection of steel grating trench cover.
5. Cast iron ditch cover plate
Material: gray iron ductile iron castings
Main uses: used for inspection wells, drainage wells and drain cover plates
The cast iron cover plate products will have quality defects such as blowholes and cracks, and cannot be repaired.
the cast iron cover plate has low toughness and high brittleness, which is in danger of fracture.
In cold weather, the surface of cast iron cover plate freezes, and the anti-skid effect is poor.
6. steel grating ditch cover plate
Material: low alloy carbon steel
Main uses: used as cover plates for inspection wells, drainage wells, drainage wells, light wells, etc.
