Storm well disposed on the houseterritory in order to divert excess water, which is formed by melting snow and as a result of rain. As one of the components of the storm sewer acts rainwater well, which has in its composition:
The shower well has a throat, throughwhich water flows into the mine. After precipitation can be used. The well is protected by a cover to exclude the likelihood of ingestion of a person and foreign objects.
The shower well can be made of plastic or concrete. Most often in the latter case, reinforced concrete is used. Depending on the purpose, the wells can be divided into:
The first kind of wells is also calledfiltering. Such structures are devoid of bottom, because they are located on the site below the occurrence of groundwater. The liquid that enters the absorption well goes into the ground. The storm sewer well is designed for areas where groundwater is quite high.
The fluid entering this structure mayused in the next stage for irrigation. In order to extract water from such a well, pumps are used. The differential storm well is installed where there are impressive drops in the earth. Such designs allow you to eliminate the flow of water that would be able to disable the system.
For the reason that such a well can bemade of plastic or reinforced concrete, the technology of installation of these structures is different. In the case of a plastic product, a corrugated pipe or well of the desired diameter is prepared in the first stage. For the work should take care of the availability of:
If required, you need to prepare a plasticbottom. Seals will be needed to ensure the reliability of the connection elements. And for additional protection of these places should use a sealant. To strengthen the connection of the mine with the bottom can be done with mastic.
Well storm sewer can berepresented by a corrugated pipe. A pit and trench for laying pipes are prepared for installation. The soil is strengthened from below with fine gravel or sand. Holes are made in the corrugated pipe that will be needed to connect the pipes.
Using a rubber seal shouldconnect piping. The joints are treated with sealant. If the well will have a bottom, then it is fixed on a concrete base. In the next step, you can begin to install the corrugated pipe.
The bottom and the pipe at the junction are processedmastic, it is desirable to use the one that is made on the basis of bitumen. Around the perimeter of the walls of the well covered with gravel, and then - with earth. At the final stage, a protective cover is installed over the shaft. The well can be made independently of plastic rings or corrugated pipe, this approach will save.
If the well is made of reinforced concrete, then it will be much more difficult to install it than plastic. For the work will need:
The bottom of the well will be a stove.In addition to cement mortar, plaster and bitumen should be prepared for sealing joints. At the first stage it is necessary to dig a hole and trenches for pipelines. A concrete slab is installed at the bottom. An alternative solution is to pour the base from the concrete mix. The foundation and rings are processed by bitumen, which significantly extends the service life of the products.
As soon as the plate dries, you can startinstallation of rings, while not doing without lifting equipment. It is important to eliminate distortions. Joints between the rings are treated with cement mortar and bitumen. After drying these materials should be engaged in finishing the walls with plaster.
На дно колодца следует насыпать песок.Primer is used for backfilling. All layers are compacted using special equipment or shovels. At the final stage, the well is covered with a lid, and a blind area is made around it. Its width should be 150 cm or more. This will strengthen the structure.
Storm water distribution wellusually it is a container made of durable fiberglass, which often has reinforced walls. This design is supplied with inlet and branch ducts. Capacity closes the lid. The input channel is usually one, whereas the output channels must be two, they are organized at different levels.
Распределительный колодец снабжается ventilation pipe. Designed for the distribution of water and fluid supply to the treatment plant. A staircase is provided inside the enclosure for ease of maintenance. The neck of the well has a diameter that is usually 60 cm. This allows the installation of a cast iron manhole top. Structurally, it is possible to install a plastic hatch. This is true for the case when the well is located in a green area.
Drainage well for storm sewerlocated in places where moisture accumulates most often, here can be attributed hollows in the ground, as well as the site under the drainpipe. Such a tank has the form of a vertical drainage pipe, into which groundwater and surface water flow. Design capacity is quite high.
If it is a linear storm sewer,then in this case the walls of the drainage well are additionally reinforced with concrete rings. However, considering the issue from the point of view of economy, it should be emphasized that the most advantageous option of the mine is a plastic well in the form of a structure with drainage pipes connected. The walls are strengthened by casing pipes whose diameter varies from 300 to 400 mm.
The device of a storm well you already know aboutThis was discussed above. However, for proper operation, it is important to know not only that. Experts recommend that you familiarize yourself with the features of cleaning. The described system requires care. After all, it can be littered with sediments and accumulated debris. Manipulations can be carried out in the following ways:
The mechanical method is used most often.for cleaning individual systems. It provides for the manual removal of dirt from gutters, water inlets, drainage channels and fluid cleaning systems. To do this, you can use brooms, mops and special devices with tips.
Hydrodynamic method for cleaning wellsalso quite common. It involves the use of high pressure technology. Destruction of blockages is carried out under the influence of a jet of water. Cleaning storm wells by this method involves the use of household pumps that supply water from a source, as it can be a specialized technique.
The thermal method is different from the one described above.the fact that sewage enters the water under high pressure and with a high temperature in the range from 120 to 140 ° C. The advantage of this approach is the possibility of cleaning the system from dirt and debris, as well as fat deposits.
The tank described above acts asthe final point that should be put when arranging the surface drainage system. Considering the varieties of such structures, it is necessary to allocate the receiving storm wells. They are installed where groundwater is high. Water comes into such a well, which can then be used to water the plants. The principle of operation of such a system is the accumulation of fluid and its subsequent use.
