Characteristics and Types of FRP Gully Gratings
1.Introduction: The Bast FRP rain gully gratings are molded from resin composites and are available in a variety of types to suit different span loads and requirements.
2.rain water gully gratings features: rain water gratings construction is simple, light weight, good load, impact resistance, Ning Bend is not folded, large displacement, beautiful and durable process after molding, anti-corrosion, with the benefits of cast iron. The use of hinged joints or hooks is easy to open and has an anti-theft function.
3.the use of rain water dice: the best drainage, high strength, specifications, low cost, widely used in municipal roads, garden equipment, residential quarters, campus, stadium tube and other different occasions.
The company can also produce other standard shapes of rainwater gully gratings according to the requirements of special customers.
(1) According to different materials of rainwater gratings, rainwater gully gratings are divided into hot dip zinc rainwater gratings and stainless steel rainwater gully gratings.
(2) According to the shape of the rainwater raft, it can be divided into: ordinary rainwater rafts, U-shaped rainwater rafts, tubular rainwater rafts and openable rainwater rafts.
Rainwater scorpion landscaping price is convenient to use and light weight: the weight of the product is only about three minutes of cast iron, which is convenient for transportation, installation and repair, which greatly reduces the labor intensity. The rainwater on the street surface first flows into the drainage pipe through the connecting pipe through the gully. The form, quantity and arrangement of the gully shall be determined according to the quantity generated by the catchment area, the discharge capacity of the gully and the form of the road.
The rain scorpion has provided us with a lot of conveniences, and it has brought great convenience to our lives. However, in the process of installing the rain scorpion, we can better serve the rain scorpion according to professional methods. Let us introduce the reinforcement method of the well ring in the rainwater raft.
Firstly, the reinforcement of the well and the installation of the rain tweezers should be carried out before the construction of the asphalt surface layer, and the shape and size of the reinforcement of the well ring are determined according to the size of the Manhole Cover and the design requirements of the reinforcement well. Generally, the square centered on the wellhead is cut by a cutting machine to excavate the pavement structure within the reinforcement range of the well. A small part of the pavement structure can be reserved for manual cutting to ensure that the groove wall is straight and tidy.
The second is to determine the height of the masonry according to the design requirements of the reinforcement well. The foundation pit is cleaned before installing the steel frame, and the low-grade strength concrete is poured around the well wall of the Composite Manhole Cover to level it. The steel frame should be processed into a square shape, which should be in line with the wellhead position during installation, and ensure the protective layer of the steel bar. The installation of the skeleton should be firm, and the concrete should be prevented from being stepped on when pouring.
The embedded bolt can be installed at the same time as the well frame or by the mold;the bolt should be placed vertically, and the nut should be fastened before the concrete is poured to make it effectively connected with the reserved holes of the concrete and the cover frame.
Rainwater scorpion has provided us with a lot of convenience and brought great convenience to our lives. However, in the process of installing rainwater rafters, we can better serve rainwater rafters according to professional methods. The following describes the reinforcement method of the well ring in the rainwater raft.
First, the reinforcement of the well and the installation of the Beast polymer composite glass fiber reinforced plastic rain tweezers should be carried out before the asphalt surface construction, and the shape and size of the well ring reinforcement should be determined according to the size of the manhole cover. And design requirements for reinforcement wells. Typically, a square centered at the wellhead is cut by a cutter to excavate the pavement structure within the reinforcement of the well. A small portion of the pavement structure can be reserved for manual cutting to ensure that the groove walls are straight and tidy.
The second is to determine the height of the masonry according to the design requirements of the reinforcement well. The foundation pit is cleaned prior to installation of the steel frame and low grade strength concrete is cast around the well wall of the composite manhole cover to level it. The steel frame shall be machined in a square shape and shall be installed in the same position as the wellhead and ensure the protective layer of the steel. The installation of the skeleton should be firm and the concrete should be prevented from being stepped on.
The embedded bolts can be installed at the same time as the derrick or through the mold; the bolts should be placed vertically and the nuts should be fixed before the concrete is poured so that they are operatively connected to the reserved holes of the concrete and derrick.
