Concrete tray - types: drainage trays of concrete goods,

In order to protect against the processes of corrosion and negative phenomena of communication, it is necessary to use high-quality and durable products. And reinforced concrete trays just have the necessary set of characteristics in order to protect cable systems and communication pipelines from negative impacts, while at the same time providing access to them in the event of an emergency.

In addition, trays of concrete can serve as a good drain for discharge from the building of thawed and rainwater.

Types of trays of concrete to the destination

Production of products of this type is conducted from a solution of the brand M200 and above. Such structures in the production process are reinforced with reinforcing rods of class A-1 and A-2, or with the help of wire brand Bp-1.

The use of the method of vibration compaction of a concrete structure in the process of manufacturing allows us to finally obtain products of dense structure, capable of withstanding aggressive environmental influences.

According to the data specified in GOST 21509-85, high requirements are placed on trays of concrete in the following parameters:

• Low Temperature Resistance;
• Moisture proof;
• High technical characteristics of reinforcing steel;
• The optimum thickness of the concrete layer;
• Ability to resist corrosion processes;
• High quality materials used to create mortar;
• Uniform structure, eliminating voids and shells;
• Resistance to mechanical stress.

According to the design of the product itself and the main purpose of the application, the trays can be divided into three main types:

1. Drainage;
2. Cable tray;
3. Tray for heating.

Drainage trays of concrete goods

Concrete rain tray is designed for collecting and transporting water.

There are also several types of such products, which differ in the purpose, design, and functions that they perform:

1. Drainage - allows you to divert rain and soil moisture from the ground floors and foundations of buildings and structures;
2. Prikromochny - removal of moisture from the roadway to the slopes;
3. Telescopic - channel channel moisture removal from bridges and slopes;

1. Stormwater - collection and disposal of stormwater;
2. Sewer - transportation of wastewater to the collectors of the system;
3. Culvert or runoff gutter - abstraction of excess moisture by the method of drift.

Types of trays for drainage

The shape and appearance of trays of concrete products for removal of moisture are of the following form:

1. Parabolic;
2. Trapezoidal;
3. U-shaped;
4. U-shaped and in the form of a trapezoid with a rounded chute.

Depending on the conditions under which the operation will be carried out, there are continuous trays and products with a vertical drain. Also trays of such appointment can be integral and combined with various standard sizes.

Marking of products of this type contains the letter "L" and two numbers:

• 1 number - the number of the series;
• 2nd number - parameters of the vertical load for which the product is designed.

Note! The greater the value of the 2nd number, the deeper the product must be mounted.

Concrete road trays also vary in production method.

Depending on this characteristic, they are:

1. Made by vibropressing;
2. Made by casting.

Tray for laying heating mains

Specialized concrete products channels protect the heat supply pipes from corrosion processes, rodents and heat losses.

These channels are of two types:

1. KLP - trays, the design of which provides for the installation of a removable cover;
2. CLS - constructions are trays above and below the channel, interconnected by channels.

Previously, brick structures were used for these purposes, but concrete products have undeniable advantages in comparison with them:

• Ease of installation;
• Low price;
• High load bearing performance;
• Possibility of installation in seismically active zones, on weak soil and soil waters;
• Resistance to adverse weather conditions;
• Resistance to temperature changes;
• The big weight providing designs a motionlessness;
• Big operational period;
• Environmental Safety;
• Resistance to rusting and corrosion.

Tray installation в домашних условиях

Often in the process of home construction there is a need to install such a product as a concrete cable tray or drainage tray.

Instructions for the construction of drainage tray system consists of the following steps:

1. The trench is digging, which by its parameters should be twice the parameters of the tray;

Council If the system provides for the installation of a trash box, it is necessary to prepare a recess for it. A sand trap may be required if the tray is connected to the sewer.

1. A dug trench is filled with concrete in 10 layers;
2. The trash box is installed at the very beginning of the route or the thread marking the flow line is pulled;
3. The structure is collected, and placed in the created water conduit;

Council To connect the concrete joint should be used grooves and grooves.

1. Joints are reliably sealed with a concrete solution;
2. On the sides, the trays are fixed with stones, after which they are poured with rubble and earth, dug earlier;
3. From above trays are closed with bars or plates.

Observing all stages of work, you can easily create a tray for concrete with your own hands.

Finally

Concrete trays are a rather important and widely used product that allows you to prevent negative environmental effects on communication systems and to organize high-quality drainage from any surface.

The choice of such structures should be made based on the size, shape and calculated load on the product, and only then at a cost. By choosing this way, you will be able to create a high-quality and durable drainage system and protect communications from many destructive factors.

A video in this article will open you many secrets of choice and tell you about the huge number of types and types of concrete trays.
