Cast iron hatch GOST 3634 99 is designed for installation on inspection wells of underground utilities. The variety of types is associated with operating conditions, load resistance and safety precautions. The production of protective products and material requirements are regulated by established international standards.

Types of protective hatches and their purpose

Access to viewing underground communications, such as sewage, cable, and pipeline systems, is provided by the manhole of the inspection well.

The main purpose of the covers is to ensure the safety of pedestrians and cars, as well as protection from damage and clogging of underground networks.

The standard for cast iron manhole covers has been developed based on global requirements for labeling, design, testing and quality control of products. Hatches are produced in accordance with the requirements of GOST 3634 99 “Hatches for inspection wells and storm water inlets for storm drainage wells.”

Depending on the installation conditions and loads, different types of hatches are distinguished. They are associated not only with ease of installation and operation, but also with the aesthetic content of the structure and the preservation of technical parameters, regardless of the conditions of use.

Extra-heavy protective structures, with a diameter of 550 mm, a weight of 155 kg, and a rated load of 600 kN, are installed in docks and airfields.

Heavy main hatches weighing about 140 kg are mounted on main lines and can withstand loads of up to 400 kN. On urban roads with heavy traffic, products weighing 120 kg and a rated load of 250 kN are installed.

Medium products that can withstand loads of up to 125 kN are installed in residential areas and roads with limited traffic load. Lightweight sewer manholes, which weigh 65 kg, are installed on sidewalks, pedestrian areas, and lawns.

Hatches for wells are manufactured in accordance with the requirements of the established standard according to approved drawings. Castings must not contain defects that affect the strength of the product.

The design provides for at least one hole to allow the lid to be opened. It should simultaneously fly tightly to the supporting surface and fit freely into the body.

If we characterize round-shaped cast iron manholes, then there are 2 main parameters for them - the outer and inner diameter of the hole.

All dimensional parameters of the product are specified in GOST 3634 99, but in practice you can find cast iron manhole covers with a diameter of 380-810 mm. The full opening size is 450-550 mm.

The cover of the protective structure can be square in shape. The minimum side length can be 300 mm and increase by 50 mm with each step. The optimal dimensions of this design are 800 mm.

Technical specifications

Cast iron hatches must be equipped with an elastic gasket between the upper and lower parts of the structure. The material from which protective products for manholes are produced must meet the requirements of the state standard.

Manhole covers and housings are made of gray cast iron grade SCH20. If necessary, it is possible to replace the material with another brand, provided that the maximum load is ensured.

The manufacturer applies markings to the outer part of the hatch structure, and the date of manufacture to the inner part. Each product has a passport, which indicates data about the product, warranty period, and date of acceptance by the technical control department.

Each batch is subjected to strength testing and mechanical load testing.

The service life of cast iron hatches is at least 80 years, and the withstand load is up to 90 tons. They are resistant to temperature changes. The only drawback of cast iron structures is their high cost.

The construction of a technological well is associated with the need for constant maintenance and ongoing repairs of various types of pipelines. Therefore, such structures are reliable and provide conditions for access to underground communications.

Installation and operation

Tightly closed hatch covers do not guarantee complete safety and protection from various objects falling into the opening. The main purpose for which heavy material is used in manufacturing is to prevent accidental falls.

The cast iron lid is quite heavy, so it is necessary to apply a certain force to overweight and move it. Cast iron is resistant to atmospheric conditions, corrosion, durable, and does not crack under stress.

Limited access to the manhole, in which the distribution and shut-off equipment assemblies are concentrated, as well as the monitoring and control mechanisms of the systems, is provided by the manhole cover.

Well holes must be closed so that they cannot be opened by random one-sided loads or curious passers-by.

If the hatch needs to be installed on a personal plot, then the main efforts must be made when installing the supporting part of the structure. The support ring has technological holes necessary for high-quality armoring of the structure.

The cover of the sewer well should rise above the surface if it is placed on a lawn area. When installing on a roadway, a minimum slope must be provided in the area where the cover will be installed to ensure water drainage.

Ease of installation is closely related to strict adherence to operating rules. The well cover must be opened with extreme care, especially if it is made of cast iron. The heavy weight of the product may cause injury.

An open well must be ventilated, and all work may only be carried out with personal protective equipment.

Light cast iron hatch “K” for inspection wells designed for installation on sewer, water supply and utility networks. The products are installed on the roadways of streets, sidewalks, general purpose roads, pedestrian paths and courtyards, depending on the load carried by the hatches. On roads with busy traffic, a heavy cast iron hatch is installed.

A cast iron sewer hatch is a part of the sewer system that performs the function of protecting the sewage system from debris getting into it. It also serves to ensure that workers have the opportunity to maintain and repair huge highways. The only option to get into the sewer is the correct organization of technological wells, which are closed with special hatches. They do not open under the weight of cars or under the influence of ordinary people. In such wells, as a rule, shut-off and distribution equipment units, control and monitoring devices for systems are installed.
