It is quite simple to equip a storm drainage system on your own. However, for its effective operation, it will be necessary to calculate the throughput. If you carry out these works correctly, then the storm drain will be able to save you from the numerous inconveniences expressed in the malfunction of the rainwater runoff. Among other things, with the help of this system you can make any design more durable. Here we are talking about road surfaces, foundations that deteriorate due to soil washing out.
Classification of the system according to the precipitation method
Storm sewers may be of an open type, while water will be discharged through gutters outside the site. Trays can be recessed, as well as fixed or installed in tracks. The open type system is most often used in small areas, as well as in small settlements where the population density is relatively low.
If you are interested in Superstroy storm water drainage systems, then you can equip a closed-type sewage system, which involves a deep drainage system. At the same time, rain is collected by built-in trays, as well as sand traps. Through the pipes, the liquid enters the storm wells, and then with the help of pumping equipment it is sent to the sewerage network. After the sewer, the liquid enters the thalwegs, and then to the treatment plant, after - to artificial reservoirs.
If you decide to choose a mixed type system, you will have to install not only trays on the street, but also mount pipes underground. In this design, drainage is carried out by gravity, except in cases where conditions are not so favorable. These may be uneven terrain.
The network route is laid along the shortest distance before the outlet into the collector, and after - into the reservoir. In this case, non-pressure pipes based on reinforced concrete should be used. This option is suitable for reducing construction costs.
For reference
In addition to the linear method of collecting rainwater, we can distinguish the envelope method, which is more complex. But it is preferable to drain the liquid in a linear way - this is exactly the case when a simpler design is better.
Expert advice
If you are going to equip storm water disposal systems, then it is highly undesirable to combine them with drainage, since in general the system will work inefficiently. The storm water shouldwork alone, overflowing it can cause the foundation to be washed away, with devastating consequences.
Installation of the roofing part of the system
After the necessary calculations have been made, you can begin installation work. Pipes that drain liquid from the roof must have a slope that is 2% in relation to the length. This parameter should not be made more impressive.
Installation technology involves the following manipulations. The master will have to install storm water inlets. For them, holes should be made in which the receivers are fixed with bituminous mastic. After that, the existing joints are waterproofed. If you are installing storm water drainage systems, then you should decide whether they will be point or linear. Depending on this, you will need to hang the pipe or receiving trays.
The next step is to install downpipes for risers or a storm drainage system. It will be necessary to provide a closed spillway to the collector. Storm drainage can act as a receiver if the spillway is open. Drainage must be of the tray type.
Stormwater drainage systems involve installation, which is carried out using clamps. The latter are fixed on ceilings or walls. You must markup in advance, while the master should take into account the angle of inclination, which is mandatory.
Work on the ground part of the drainage system
When stormwater drainage systems are being equipped, there is a need to carry out the installation of the ground part. In this case, the installation requires compliance with a certain technology. The sequence of work involves ensuring the correct slope, for which a tracing cable should be used. As soon as the markup has been carried out, earthworks will need to be carried out. To do this, the master must prepare a trench and wells, taking into account the depth of freezing. You should dig grooves into which ground trays will be mounted. The next step is the installation of ground storm water inlets. The trenches should be well prepared, for this a layer of sand is laid out on the bottom, which is then carefully rammed.
Features of work performance
Stormwater drainage systems, photos of which you can see in the article, provide for the presence of pipes and trays that are laid in the next stage at the places provided for these elements. You should combine the elements of the sewer system, sand traps, storm water inlets and wells into one system. At the final stage, the trays are fixed with cement mortar. The gratings are being installed, and after that the pipelines can be closed.
The surface storm drainage system must be tested, for this the master must carry out a test spill. On this, we can assume that the arrangementcompleted. Such a system will be ready to serve for many years, but this statement will only be true if you operate the system correctly.
Arrangement of the drainage system
Installation of drainage systems provides for a drainage system. If we are talking about point drainage, then you need to use local drainage systems, namely wells and storm water inlets. With their help, it will be possible to collect liquid from one area, this may concern, for example, the roof of a house. Installation is carried out under a drainpipe or irrigation taps. These elements must contain grids, which are complemented by a filter basket. The latter will serve to retain debris, which is sometimes brought in for water. Drainage is connected to the underground sewer pipes, this will eliminate the flow of storm water into the well.
A do-it-yourself storm drainage system can be equipped and supplemented with storm linear drainage. This part of the system is necessary to collect precipitation from a large area. With the help of this component, it is possible to solve the problem of water disposal in a complex way. The master can use linear drainage, namely channels, trays and gutters. Inside the sand traps there should be a basket in which debris accumulates. Sewer cleanup should begin by emptying these bins.
Nuances of installation work
If you will equip storm systemsdrainage in the country, then you must follow certain rules. Initially, marking is carried out, and pipes are also prepared. Most often, the latter are made of PVC, and their diameter is 110 millimeters. The elements are connected to each other by means of a double coupling. You can replace the pillow that is laid on the bottom of the trench with crushed stone, the thickness of such a layer should be equal to 8 centimeters, after which pipes are laid on such preparation. Then the earth should be backfilled, each layer should be well tamped. Attention should be paid to the point that the system must be installed vertically under the downpipe.
