Design And Notices Of Steel Grid Trench Cover
Galvanized steel plate or stainless steel grating can be used for the material selection of stealth well cover. The main structure of the inner and outer frame is all bent into "L" form. It is welded and welded. The inner frame is optional welding steel, and the strength and stability of the inner frame can be strengthened, and the filled mortar can be effectively attached. Because of its compact structure and better load carrying performance and stability, the structure has been widely used in most occasions, such as residential roads, street facing and so on.
The design of the steel grid trench cover is to ensure the smooth passage of the disabled and improve the overall landscape of the sidewalk, and the "recessive" of the inspection wells on the municipal public pipeline on the sidewalk, and the detailed design of the cover structure of the stealth well. The hidden well covers consist of top steel grooves and steel grille plates. An embedded piece of steel frame consisting of a steel frame at the time of installation. The hidden well cover is applied to a circular well with a square or diameter R < 800mm at side length L < 800mm; the stealth well cover two is applicable to the cable well or the cover well with a width of L > 800mm. When the manhole cover is overhauled, the concealed manhole cover should be placed as smoothly as possible, so as to avoid the side or side stand placement.
The stealth Surface Layer Paving on the sidewalk is consistent with the pavement brick pavement material, and should be connected to the blind road brick. When the cover is across the non motorized lane and the sidewalk, and the sidewalk is not coplanar with the non motor vehicle road, the invisible well cover is located in the area of the non motorized driveway for cover treatment. The surface is paved with the non motorized lane. Use self tapping screws to fix on the stealth manhole cover. If necessary, use strong glue on the back. When installing, the logo should be kept consistent with the pavement. If the gas and electric well logo pattern part uses the stamping process to make the concave 0.5mm, the red reflector should be painted in the groove.
Matters needing attention
(1) in principle, the double ended manhole cover is used in the circular inspection well, and the single well cover is used in the square wells such as cable trench.
(2) before the construction of the stealth cover of the municipal inspection well, the total thickness of the stealth well cover should be determined according to the location of the location of the location. Accordingly, the original municipal well head height should be reduced and the 50mm clearance is reserved for the stealth well cover to be leveled. The riding inspection covers should be combined with a variety of pavement materials, and the color and texture of all materials should be integrated with the surrounding pavement.
(3) steel grating plates are only used for sidewalks and non motorized lanes.
(4) attention should be paid to the installation of the cover of the stealth well: when the cover is covered on the hard pavement, the cracks in the cover of the well cover are consistent with the cracks in the surrounding stone, and the opening direction of the cover of the same section and the area is consistent.
(5) the link between the inspection well and the road should be smooth, and the cover of the wellbore on the sidewalk should be covered with the cover of the stealth (the cover of the well cover and the pavement of the sidewalk). The check well frame should not be more than + 5mm, and the height difference between the well cover and the well frame should not be more than + 3mm. The type of professional pipeline should be marked on the inspection manhole cover.
(6) the invisible manhole covers made by factories need to provide all kinds of raw material reports, factory certificates and other related documents, and send the finished products for testing. Site production requires professional qualification, raw materials need to be submitted for inspection, finished products need to be tested, and construction should timely send samples and check.
