The problem of drainage is relevant for any territory on which rainwater can accumulate. For the purpose of its collection and lead, special surface drainage systems are used, the main elements of which are trays for storm sewage.
Despite the seeming simplicity of products, trays will be able to fully fulfill their work only with the right calculation and choice. It is necessary to take into account the intensity of the movement in the place, equipped with railways, the degree of water pollution, the maximum system throughput, the type of surface coverage of the territory.
What is needed and where trays are used
Storm sewing solves the following tasks:
- removal of rainwater from certain territories;
- Protection against the flooding of all kinds of structures, structures and buildings shown below the soil level;
- maintenance of soil in solid and dry state, its protection against possible erosion;
- Extension of the operational resource of sidewalks, roads, cabins and other solid coatings.
Waterproof gutters are used in the following areas:
- Framing of roads, railway tracks, pedestrian tracks;
- In industrial enterprises in order to remove precipitation and other waters from the territories of workshops, warehouses, parking lots, locations of technology. Concrete or reinforced concrete trays for water removal are predominantly used;
- drainage from buildings, houses, gas stations and other facilities;
- In the parks, in the squares and other territories such gutters are used to maintain in the purity of tracks, open places, lawns;
- For removal of water from country houses, cottages, hozpostroops. For this purpose, plastic and composite trays with a slight weight are popular.

What materials are made trays, their standard sizes are manufactured
For equipment of the drainage system, channels of various profiles, sizes made from a variety of materials can be used. For their proper choice, you need to know the features of each of these species. The main difference of trays is the material of the manufacture, so we will pay the maximum attention to this issue.Concrete trays
Heavy but very Reliable and inexpensive Concrete trays are perfectly coping with water assignment even in large volumes. The inertness of concrete (fibrobeton) to aggressive composition allows you to remove salt and other chemical compounds from the foundations of buildings and road surfaces. These are the most reliable of all kinds of similar products that can withstand significant weight loads.

As a flaw can be noted Big weight tray , because it can start with 100 kg. This factor increases the cost of their transportation and installation, as you have to use loader techniques and a large number of workers.
Concrete trays for landfill are installed using the technique
Standard sizes of concrete and reinforced concrete chutes:
- Length - 1 m;
- Width in section - 10-50 cm;
- The height of the design is 9-76 cm.
Plastic trays
Polypropylene and polyethylene (PND) are used for the manufacture of plastic channels. Plastic trays for storm sewage is resistant to most chemicals in rain and wastewater. Them Bottomy is very high Due to the smooth walls on which garbage is not delayed. Small weight of products (up to 15 kg) makes it possible to easily transport them and install trays with your own hands. The use of loading equipment is excluded.
Disadvantages of plastic also take place. Channels have less durability compared to concrete samples and, slightly less durability, as well as higher cost.
Plastic gutter for landing
The most popular dimensions of plastic lavender trays:
- Height with or without lattice - 6-30 cm;
- width - 14-20 cm;
- Standard length - 1 m.
Polymer concrete trays
Such products are gaining popularity due to the combination of positive qualities of concrete and plastic. They are produced from granite crumbs, quartz sand or materials similar to it in combination with epoxy or polyester resins. Polymer components are replaced with cement. Gutter from Polymerbeton have low weight, but significant strength and flexibility. They differ from concrete analogues with smoother walls that improve their bandwidth. Moreover, the load on composite trays can be maximum, as for concrete drainage.
Polymer concrete drainage tray with metal grille
The polymer concrete storm tray has the following dimensions:
- Tray length - 1 m;
- width - 7-30 cm;
- Height - from 5.5-12.5 cm.
Polymer trays
For the manufacture of grooves from such a composite material as a polymer monitor, a mixture of fine sand and a polymer crumb is used. The mixture is heated to the temperature of its melting, and then presses. Products of a given form are obtained at the output. Trays combine in themselves Elasticity of plastic and quartz strength Therefore, can be used in most cases of storm sewage pads. Moreover, their The cost of them is low, and the weight is twice as smaller than that of concrete channels.

Polymerpessic drainage tray
Sizes of polymerpess trays:
- Length - 1 m;
- Height - 7-12.5 cm;
- Width - 140 cm.
Note: It is also necessary to say about the existence of pig-iron trays for the lavety, but possessing a lot of weight and high cost, these products do not have advantages compared to others.
Load classes tray
To properly select the stoves for storm sewage, it is necessary to take into account the level of loads acting on the surface with the trays located on it. To do this, pay attention to the classes of the maximum permissible loads, which are assigned to such products.A15
The load on such trays is minimal. They can withstand only 1.5 tons. Therefore, they are used in places like children's and sports grounds, small areas, parking, private possessions, cycling and pedestrian walkways.
In 125.
For such products, the load can be increased to 12.5 tons. Suitable for equipment for car parks, roads with a small intensity of motion, drainage from private houses and garages.With 250.
Limit loads for such a class of products - 25 tons. Application areas: equipment of gas stations, roads, removal of water from the house territories in cities.
D 400.
The load - up to 40 tons allows the use of trays at industrial facilities, on high-intensity motor vehicles and the presence of heavy trucks.E 600.
High load, calculated 60 tons, makes it possible to use products in the shops of enterprises, on marine berths, warehouses, places of accumulation and movement of massive goods.
F 900.
This is the maximum load indicator assigned to products. The trays of this class are used in places of concentration and movement of large-sized military and industrial equipment. For example, at airfields, military facilities, some enterprises.Installing stoves for storm sewage
The installation of drainage trays is the process of responsible and time consuming, but when complying with all the installation rules, it is quite possible to mount the drainage trays with their own hands.
Storm sewage from drainage trays
Work is performed in such a sequence:
- It places the territory under the trench of the corresponding width. Be sure to take into account the slope of at least 1 cm on the trafficphone meter for the best samotek of water.
- Trench is thrown throughout the length of the catchment.
- The bottom of the trench is rambling.
- A sandy pillow falls asleep into the trench.
- The bottom and walls of the trench are flooded with a liquid concrete solution.
- If necessary, the sands are first installed. Next, trays are installed on top of the solution. Each of them is joined with a nearby tray. It is allowed to be mumbled with a hammer along the walls of the tray to give it the corresponding position.
Options for stacking trays for water removal with sand-tractor
- Trays are covered with lattices that should be below the surface level by 5 mm.
- At the turns of the trays are joined among themselves by cutting out the marked holes or with the help of rotary inserts.
- All the junctions between adjacent trays are flooded with sealant.
Rain trays installation circuit
Tip: For accurate installation of trays and give them the desired inclination, use the construction level. On the "Eye" to produce such an installation is very problematic.
Recommendations for the operation of storm sewage
Systems of surface drainage periodically must be cleaned of garbage from them. For this purpose, the following methods of cleaning are most often used:- Mechanical cleaning of trays with screwdrivers. It is conjugate with the removal and re-installation of the lattices;
- Hydrodynamic purification of water under pressure. In this case, only one grill is removed for the hose institution in the channel. Water rushes through the canal, leaning all the garbage. It is performed using fire equipment or special devices that create high water pressure.
There are also other ways to clean the ravery, which are applied less frequently, to clean the channels from ice. Thermal purification implies the supply to hot water channels, and chemical cleaning is based on the use of chemicals to remove ice layers. However, the last two ways are not so popular.
Tip: In order not to spend a lot of efforts to clean the already scoring drainage systems, timely show care of landlines, producing their regular prophylactic cleaning in the process of the entire year.
The drainage system collected in all rules will provide high-quality surface drainage of the territory for many years.
Price on storm trays
We present information about the approximate value of some of the elements of drainage systems described above. It will depend on both the material of the product and its size and configuration.
For example, on concrete trays for storm sewage, the price will start from 360 rubles behind the product of the standard length of 1000 mm (width - 140 mm, height - 125 mm), plastic trays of the same length with a galvanized grid can be purchased for 550 rubles (width - 116 mm , Height - 96 mm). Polymer concrete drainage gutters with dimensions of 1000 * 140 * 70 mm will cost approximately 820 rubles.
