Dimensions of sewage manholes, polymer, technical specifications, installation

The construction of any building involves the arrangement of engineering communications, most often when using special wells. Such designs allow for easy and quick maintenance of systems as needed, ensuring operational safety, reducing the risk of emergencies. The construction of such systems involves the use of polymer hatches, which are installed on inspection wells.

general description

Until recently, most often used products made of cast iron. Polymer hatches are elements made from a number of components, among them composite ingredients. In the production process, hot pressing technology is used. The hatch sewer polymer-sandy - this is one of the varieties of the mentioned products. Among other things, the classification is based on the intensity of the load on the surface of the product. By this principle, it is necessary to distinguish some groups of goods, namely, heavy and light.

Marking hatches

Hatches sewer polymer-composite are issued with an indication of the appropriate marking, which determines the direction of use. When buying, you should pay attention to the abbreviation, located on the front surface of the structure. The letters G and PG indicate that the product is intended for ground and underground protection of the fire hydrant. "B" indicates the possibility of using manholes in water mains, while the letter "D" indicates that the sewage hatch is used as a storm shower.

Main positive characteristics

Hatches sewer polymer square and round have significant advantages, if you compare with analogues made of other materials, such as wood, steel or cast iron. The positive features include a long service life, which lasts more than 50 years. Among other things, the products are sufficiently resistant to corrosion and fracture, which could occur when exposed to any kind of aggressive environment. Installing products is fairly simple, since they have a negligible weight, the mass of one unit of production can vary from 10 to 35 kilograms. This fact facilitates the process of transportation. The duration of life is also determined by high resistance to solar radiation. On sale you can find a wide range of models that have different decorative features, as well as shades. Designs are excellent at high temperature, they can operate under a wide temperature range from -10 to +50 degrees. Due to the fact that there are no toxic substances in the composition, the described products can be called environmentally safe. The hatch sewer polymer, the technical characteristics of which are presented in the article, can be used instead of cast-iron products, which indicates interchangeability. Consumers note a high level of protection, this indicates that the products are equipped with special locks, which eliminate the possibility of theft.

Varieties in the form

Manhole sewer hatches, plastic, polymeric, plastic are manufactured in the factory with different shapes. Thus, round structures are required for private or repair work in sewer wells. This form is used most often in comparison with others because the inspection shaft assumes the need to install such products. Choosing a certain model, you need to be guided not only by performance, but also by dimensions. If we talk about the general purpose hatch, we should consider the main quality characteristics of the design, among them the inner and outer diameters of the shell. It should be mounted on the upper end of the well, while its parameters should correspond to the dimensions of the neck as much as possible. If you are interested in the dimensions of sewage hatches polymer, you need to know that on the sale you can find designs with an internal opening diameter ranging from 315 millimeters to one meter. If there is a need, then you can also prefer square products, there are no restrictions on the typical dimensions of such hatches. Manufacturers make them with some step, which is equal to 50 millimeters. The most minimal size is 300 millimeters, while the maximum is 800 millimeters. When choosing the sizes of sewage hatches polymeric, it is necessary to pay attention to the fact that the cover can be hermetic or have special slots. The latter option is used to equip storm sewerage in both private and industrial construction.

Recommendations for using the hatch

It is not only the dimensions of the polymer manhole covers that are important, but also the compliance of the technology with their installation. The master will have to put the gasket, install the hatch itself, after leveling the surface. A number of professionals recommend that the hatch and rim of the well additionally mount hinges on which the lock is hung. If there is a shut-off hatch, you should check for gaps and cracks every year. They can affect the efficiency of the system. If any damage has been observed, it is recommended to replace the product. If the hatch has been installed in the northern region or the area with high precipitation, then additional protection of the hatch should be made using a special panel. It can be made from a variety of membrane materials, however, as an alternative solution, traditional foam can be used. Suitable and thermo panels, as well as other similar coatings. This will protect the product from the negative impact of the environment and extend its life. Regardless of the condition, it is recommended that the lid be replaced every seven years.

Installation of a plastic hatch

Whatever the size of the sewerage hatches polymer you were chosen, the installation works are carried out using the same technology, the process will not be difficult. Initially, a ring is installed on the floor, which is made of reinforced concrete. Then the ring is poured with concrete of a suitable brand. The next step is to install the hatch cover in the ring. However, these manipulations should be carried out only after the concrete has hardened. The product should be placed strictly horizontally with respect to the surface of the earth. Raise it above the soil level should be 5 cm.

It is important to equip the blind area, which is located around the polymer hatch. It must be sloped to remove excess moisture. It should be given a width in the range of 1 to 1.5 meters. If you want to simplify the work, then you need to choose models that have special mounting grooves.

Cost

If you decide to use a sewer hatch, the price of this product should certainly interest you. Having visited the store of the corresponding goods, you can buy a hatch, paying 800 rubles for one unit.

Conclusion

Recently, with the arrangement of engineering systems, the most commonly used hatch sewage polymer, the price of such a product is available, which is why such structures have found wide distribution both in industry and among private consumers. Perhaps, you should pay attention to this solution.
