Concrete storm (rain) channels for sewerage: reinforced concrete, with a grate

Modern sewerage systems must have concrete storm channels in order to effectively control rainfall runoff and avoid flooding. These channels are essential for moving excess water away from streets, buildings, and other urban infrastructure. They are frequently constructed of reinforced concrete and have a protective grate on top. Even in the worst weather, their sturdy construction guarantees longevity and durability.

Storm channels made of reinforced concrete are especially well-liked because of their durability and resilience to damage. The reinforcement—typically steel bars—improves the concrete’s resistance to pressure and large loads, which makes them perfect for high-traffic areas. The channels’ lifespan is increased by this extra durability, which also lowers maintenance expenses and the need for frequent replacements.

In order to minimize blockages and maintain smooth water flow, the grates that cover these storm channels are essential in keeping debris out of the sewer system. These grates are made of different materials and designs to suit different needs and aesthetic tastes. The grates improve safety in addition to their functional advantages by averting mishaps and injuries that might result from open channels.

An enduring and effective way to manage rainwater is to integrate concrete storm channels into sewerage systems. Urban environments are kept safe and functional even in the midst of heavy rainfall thanks to their carefully chosen design and materials. We can recognize the significance of these channels in preserving efficient and long-lasting water management systems by comprehending their advantages and characteristics.

Storm sewerage system

A storm drain, sometimes referred to as a storm sewer, is a unique type of drainage system made up of pipelines, water receivers, inspection wells, filters (to collect debris), and a sizable rainwater collection well. When all these components are combined into a single system, you can efficiently remove extra water from spaces and objects so that gravity pulls it away.

Where it accumulates the most is where rain and melt water collection is arranged. The first part of the system consists of concrete sewage trays, drain pipes and funnels, and water receivers under drainage pipes close to sidewalks, roads, locations, etc.

The sewage system can be linear and cover all surfaces (paths, sites, roofs) or point-based, with rainers installed only under drainage pipes, depending on the type of water collection.

• The area from which water is removed.
• Average precipitation in the climate zone.
• Characteristics and properties of the soil.
• Communications that are underground.

The most common material used to construct the drainage system is 11–12 centimeter polyvinyl chloride sewer pipes, which are robust and long-lasting enough. Installing pipes facing the storage tank requires a 5 centimeter slope per linear meter. The arrangement of storm sewer pipelines is similar to that of residential installations.

Inspection wells are used to service the system and quickly clear obstructions. In both closed and mixed storm sewer systems, a well must be installed at the lowest point. Water is accumulated, distributed, and released from a well; the well’s volume must match the liquid’s volume.

Concrete (or polymer concrete), plastic (long service life, resistant to various impacts), and metal (mandatory waterproofing) can all be used to construct a well. The greatest choice for a suburban area is a concrete sewer storage well, but you’ll need to consider how to deliver and install it because of its heavy weight, which calls for specialized equipment.

A bottom is created in the well by pouring concrete or using a finished product for optimal operation. On top of the well is a cover that has a hatch.

You can also make a sewerage tank yourself: dig a pit, fill it with sand and crushed stone, concrete the bottom, make formwork and lay a reinforcement frame in it, install pipes, concrete, and perform waterproofing. Next, a cast-iron grate is put in place.

It’s a good idea to consider how the collected water will be used later on, such as for household, industrial, and irrigation purposes (but only after cleaning). Water collection trays can be made of concrete, composite, or metal. A concrete tray is typically selected because of its clear functional benefits.

A concrete tray with a grate is installed to prevent injuries and the entry of different debris into the system, safeguarding and making the product’s surface safe. Grates are typically composed of metal.

Classification of concrete trays

Concrete trays are manufactured in compliance with GOST 21509-76, 26633-2015, and 13015-2012. P, U, trapezoidal trays are used for water drainage. Because the products are frequently made with a structural slope, water flows through the trays naturally (or without).

– the highest load that high-power products are designed to handle; these products are installed on the grounds of airports, military installations, and spaceports.

Trays are made using the vibrocast and vibropressed methods. While the second technology considerably raises the quality, the first technology assumes a lower strength and durability of the finished product.

Characteristics of drainage trays

The purpose and production method of concrete drainage trays dictate their technical characteristics and properties. The higher the grade of cement used in the tray’s construction, the greater the load that it can support. Steel rod reinforcement is used to strengthen.

• Compressive strength – corresponds to at least concrete grade M300.
• Filler fraction – maximum 15 millimeters.
• Cement for production – minimum grade M400.
• Concrete thickness above the reinforcement – a layer of at least 15 millimeters.
• Appearance – absence of any irregularities and drips, cracks and chips.

The products’ dimensions can vary; standard models assume a length of 1000 millimeters, but width, height, and wall thickness can also vary.

Advantages and disadvantages

The primary benefits and drawbacks of any storm drain tray are dictated by its manufacturing characteristics. Vibration pressing produces high-quality products with superior features and technical characteristics, making them the most popular.

• High resistance to moisture, sudden temperature changes.
• Resistance to dynamic loads and corrosion.
• Safety in operation and environmental friendliness.
• Long service life – up to 70 years.
• Good mechanical strength.
• Universality of use of the element for creating various systems.
• Stability due to high weight, which is especially important when large volumes of wastewater accumulate.
• Ease of installation and maintenance.
• Relatively low cost.

It is important to note that this type of reinforced concrete product has certain drawbacks, including its high weight, the requirement for special equipment at the site, and relatively high transportation costs.

Effective sewerage systems require concrete storm channels, which are frequently constructed of reinforced concrete and have grates on top of them. In order to minimize flooding and water damage, these channels effectively divert rainwater away from buildings, roads, and other structures. Smooth water flow is ensured by the grates, which keep debris out, and durability and longevity are guaranteed by the use of reinforced concrete. The advantages, installation procedure, and maintenance advice for these essential urban infrastructure parts will all be covered in this article.

Production of concrete trays

There are several ways to make drainage trays: you can pour them yourself at home or in a factory using vibration casting or vibration pressing techniques.

Production in factory conditions

Businesses most frequently employ the vibration pressing method, which increases the time and cost of product creation but ensures the right quality—particularly crucial when pouring products with strict specifications.

• Mixing concrete mortar from M400 cement, sand, fine/medium crushed stone (1:2:4), mixing with water.
• Pouring the mortar into a prepared form installed under the press. The products are reinforced with steel rods with a diameter of 5-6 millimeters, pre-treated against corrosion.
• Pressing the elements with the removal of air and excess moisture.

Independent production of trays

Using boards or plywood, create a U-shaped formwork and cover it with a polyethylene film to create drainage trays by hand. After that, combine the mortar, insert the reinforcing rod into the form, fill the formwork with the mixture, and press half of the sewer pipe in (this will produce a depression with a smooth surface that has the required shape). The building is taken apart in a single day, and the tray is given 28 days to strengthen.

It’s best to use a deep vibrator, bayonet with a reinforcing rod, or tap the form on a regular basis to get rid of extra air.

For efficient water management, concrete storm channels are crucial, especially in locations that frequently experience high rainfall. By effectively directing rainwater away from structures and roadways, these channels reduce the chance of flooding and structural damage. These channels can handle a lot of water and withstand severe weather because reinforced concrete is used in them, which gives them strength and durability.

These storm channels have grate covers that add another level of security and functionality. By keeping debris out of the drainage system, the grates lower the possibility of blockages that could cause flooding. By obstructing open channels, which can be dangerous for both cars and pedestrians, they also improve safety.

All things considered, reinforced concrete storm channels with protective grates are a reliable option for contemporary sewer systems. They are essential in preserving the integrity of urban infrastructure because they effectively manage rainfall and guarantee the proper functioning of drainage systems. Building high-quality storm channels can help create safer, more resilient environments while sparing communities the expensive effects of flooding.
