When arranging a centralized and autonomous sewage system, a well is installed without fail. It allows you to periodically maintain and clean the sewage disposal structure. Well polymer today is in demand among consumers. This is due to its characteristics and reasonable cost.
Plastic wells allow you to clean the resulting blockage, check the sanitation. You can install such an element of the system yourself. What to look for when choosing, as well as how to install, should be considered before starting work.
Appointment
A polymer well is a device that allows control and provides access to sewage pipes. In addition, there are varieties of designs in which you can store the electric cable. Wells are used in storm-drainage, drainage, fiber-optic, gas, sewer, telephone and other networks.
To perform its functions, the product has a bottom, a shaft (body), a neck and a hatch. Also in its structure may include bends and pipes, supply communications. Previously used brick wells. In their place came new materials. Reinforced concrete varieties require special installation costs. Therefore, many owners of private homes prefer polymer options.
According to building codes and regulations, such products must be installed in all drainage networks. It must be installed in places of rotation or change in the level of pipes.
Design
Each well has basic structural elements. The first of these is the bottom. It allows you to tightly close the inner space from the ingress of groundwater or liquid from the well itself into the ground. This element must withstand significant loads.
Polymer manhole covers have standard sizes. They are laid on the neck, if the cover belongs to a variety of pedestrian or technological. If the hatch is automobile, it is mounted on a special base plate. This prevents the asphalt from being pushed near the well.
Pipes connect the system with various communications. They can be created for PVC outlets, corrugated pipes. The designation of the diameters of the sections can be performed on the inside or outside.
Types of wells
The presented elements of the drainage system can have various dimensions. This characteristic is determined by the daily disposal of sewage. Depending on the purpose, there are a viewing, water intake and polymer-sand well .
Also distinguish household, drainage, production and storm wells. They can be made of polyethylene, PVC, polypropylene, a mixture of various polymers.
According to the manufacturing technology, welded and solid structures are distinguished. If you want to install a sufficiently large well, it can be assembled from several parts. But for a small mine, an integral type of structure is suitable.
The difference between the wells also lies in the interior. There are products with smooth walls, as well as corrugated varieties. In the latter embodiment, one-and two-layer walls are distinguished.
Cost
Modern polymer wells, the price of which can vary significantly, can be characterized by various qualities. According to customers, such structures should be strong enough, resistant to groundwater pressure and other loads.
To ensure that the products presented comply with sanitary and construction requirements, most often, when creating their design, stiffeners are provided. Such wells cost about 15-25 thousand rubles. Such structures are able to withstand various adverse environmental influences and last a long time.
Smooth-walled structures are also on sale. They do not differ in high durability. Their cost may be in the range of 6-10 thousand rubles. According to users, such products are not able to withstand even one year of operation under the condition of a snowy winter.
Polymer manhole covers are sold separately. Their cost can vary from 1 to 5 thousand rubles. When choosing, it is necessary to take into account operating conditions, the size of the loads that will affect the system.
Hatch strength class
A polymer well may have various dimensions, strength, and the number of constituent elements. The final cost of the construction depends on this. When choosing, you should also pay attention to the class of the hatch. This is one of the most important components of the system. There are 4 classes of covers for wells.
The D400 standard is intended for highways. It is able to withstand maximum loads. For the arrangement of sewage systems inside the city, where the hatch opens onto the carriageway, the C250 product is suitable. It can withstand loads up to 25 tons.
For sidewalks, park areas, a B125 class hatch is quite suitable. It is also used in parking lots. For a private house, it will be enough to purchase an “A15” type hatch if it opens onto a green lawn or pedestrian walkway. In this case, the cost will be significantly lower.
Plastic benefits
Sewer polymer wells have several main advantages. The presented designs are highly durable. If necessary, they can be further enhanced. The tray part is resistant to wear, which can significantly extend the service life.
The inlet and outlet nozzles are connected to the well hermetically. Factory connections also have a high level of tightness. In the manufacture of the design, you can specify any dimensions of the product.
Installation of plastic wells is quick and easy. The costs of their acquisition and installation will be minimal. Plastic is resistant to the aggressive effects of effluents. The presented products are practical, affordable. This makes them in demand today.
Features of choice
In order to properly operate the sewage system, it is necessary to pay attention to the correct choice of the type of product. There is a polymer-sand prefabricated well , inspection and water intake structures.
In the first embodiment, the product has a length of 2 m and a shaft width of 1.5 m. There is no throw at its bottom. Here, drainage material (crushed stone, gravel) is poured, which passes the treated effluents into the ground. Thanks to the special design, such structures capture sand and other small particles without passing them into the soil.
Manholes are required in potentially hazardous areas of the water supply. In such places, communications change their direction. If a breakthrough occurs, the master will be able to get to the pipe and fix the problem.
Storage facilities hold drains inside themselves until they are pumped out. This option is used in areas where there is no centralized sewage system. In order not to send drains into the ground, a similar system is used.
Prefabricated and monolithic structures
The buyer has the opportunity to choose prefabricated or monolithic structures. In the first case, polymer rings for a well are acquired . They are assembled at the installation site. Using these elements, you can assemble a building of almost any depth. Each component has an o-ring. The tightness of the well depends on their quality. The more components are used to create the structure, the more flexible it will be. But this increases the likelihood of leakage.
If you want to provide increased compressive strength of the walls of the well, monolithic structures should be purchased. It is important to correctly assess the amount of water that will be inside.
Materials
Sewerage in a private house with your own hands, a scheme of which is developed taking into account the characteristics of operation, can be created from various materials.
PVC systems are highly resistant to aggressive substances, as well as incombustible. However, in conditions of temperature differences and the need to ensure a high level of tightness, it is better to give preference to wells made of polyethylene. They are able to withstand soil pressure even in severe frosts.
If it is likely to affect the walls of the soil structure, it is recommended to install structures made of polypropylene. It is a ductile, durable material that is resistant to wear. It can also be soldered. Therefore, prefabricated structures are preferable to create from polypropylene.
Installation Features
Sewerage in a private house with your own hands, the scheme of which is not very complex, is mounted in several stages. In this case, you do not need to use additional special equipment. Installation does not take much time.
First you need to dig a pit. It should be 20 cm wider than the well. The bottom is lined with gravel. If you plan to create a cumulative structure, the base is concreted completely. For drainage varieties, cement is poured only around the perimeter.
The well with the help of special equipment is introduced into the pit and fixed with cables. Next, connect the sewer pipes. The tank is filled with water and backfilled. A technological ring is installed, a manhole cover.
After a proper leak check of all elements of the system, the sewer well can be operated for its intended purpose.
Having considered what a polymer well is, as well as its features and varieties, each owner of a private house will be able to independently choose the best option. Do-it-yourself installation, performed in accordance with the recommendations of building codes, will be carried out quickly and efficiently.
