What types of wells are there?
A reinforced concrete well’s dimensions, components, and volume can vary. The system’s operational requirements and required functions dictate all of this. As a result, the requirements for a storm or sewer well will be entirely different from those for a water well. However, the default design configuration is used as a starting point in any case.
Structure
The bottom, wall rings, cover, and hatch are the four main components of any reinforced concrete well. Wells with floor slabs are used in road construction, and square tanks are occasionally installed in sewer systems, but these are the exceptions rather than the rule.
– Monolithic slabs of reinforced concrete that serve as the well’s bottom and shield it from groundwater.
Ordinary water or sewer manholes look like this, but alternative designs are also possible. Therefore, sometimes a ring with a bottom is installed in place of a bottom, or the site is concreted by pouring concrete. If the manhole is located on a road, a rectangular support plate is used to cover it instead of a lid.
Unified sewer reinforced concrete manholes, which are constructed as a solid cylindrical block with a bottom and a pre-made hole for the pipe reinforced with metal mesh, are frequently used to form storm drainage systems.
Purpose
There are three primary product categories based on the kinds of systems that reinforced concrete manholes are utilized for.
Pipelines with a maximum diameter of 30 centimeters are typically designed for autonomous home systems, and wells are composed of meter-diameter round rings. Large-diameter rings are used to set up a mini-pool or cellar in a private residence.
According to GOST 8020, all unified and prefabricated products used in the construction of sewer and drainage systems are made from concrete of classes B15–B22.5, with a minimum degree of frost resistance of F150 (the number of freeze/thaw cycles that a product made of reinforced concrete can withstand without deteriorating and being destroyed).
There are several varieties of reinforced concrete wells, each with a distinct function. Storm wells handle precipitation runoff, sewerage wells manage wastewater, prefabricated wells provide flexibility and ease of installation, and water wells guarantee a clean supply of water. Because of their robust construction and long lifespan, these wells are able to tolerate large loads and challenging weather. Knowing the various kinds and how they are used will help you choose the best well for your purposes, guaranteeing effective and durable performance.
SNiP requirements for the device of sewer wells
The operating conditions and features of the structure being built must be considered when selecting reinforced concrete wells and their configuration. For instance, wells equipped with rectangular floor slabs with hatches are used for systems situated on highways, and reinforced concrete rings with a bottom are used for waterproof structures.
Every reinforced concrete well is made using heavy concrete of class B15 in compliance with GOST 8020-90, series 3.900.1-14 specifications. The concrete from B20 is used for support slabs. For well working chambers, the minimum frost resistance of concrete is F75; for other products, it starts at F100. W6 is the standard for water resistance.
Volumetric reinforcement cages manufactured on specialized machinery are used to reinforce the working chambers of wells. Round reinforced concrete pipes are reinforcing with the same cages. Ordinary reinforcement meshes may be bent to create cages during road construction.
Meshes cut from volumetric frames in the areas where openings occur reinforce the bottom of the wells. Water and gas wells are an exception, as their bottoms are strengthened with unique reinforcement meshes.
The following classes and types of reinforcing steel are appropriate for strengthening: thermomechanically strengthened rod classes 5781, hot-rolled rod classes A-I-III according to GOST 5781, and wire class Вр-I according to GOST 6727. As per GOST 10884, At-IIIΡ/At-IVС. Every manhole structure is constructed in compliance with SNiP 2.04.03.
For inspection manholes
Installing inspection manholes at pipeline connections—where the pipelines’ direction, diameter, and elevation change—is a good idea. The control points are located closer together the thinner the pipe. The largest diameter is used to determine the manhole’s size in the home and commercial sewerage plan.
- If the pipe is less than 60 centimeters, the manhole should be 1 meter in diameter.
- Pipe from 60 to 70 centimeters – manhole 1.25 meters.
- 80-100 centimeters – 1.5 meters.
- 100-120 centimeters – 2 meters.
- For a small diameter pipeline with a laying depth of less than 120 centimeters, manholes with a diameter of 70 centimeters can be installed. If the depth reaches 3 meters, a round manhole must be at least 1.5 meters in size.
- Working height – from the bottom to the support point of the ceiling. For a sewer well it is equal to 180 centimeters. To descend into this part, a stationary or hanging ladder must be mounted (steel brackets are also possible). If the depth is from 1.5 meters – a fence is also required.
- The standard well neck is 70 centimeters, but at the turning points (this is where blockages most often occur), the dimensions of the manhole are increased so that cleaning equipment can be lowered.
- Hatches should be mounted 5-7 centimeters above the ground for a green area, 20 centimeters higher for an undeveloped area, flush with the soil for a roadway or sidewalk.
- If the bottom of the well is located below the groundwater level, it must be protected from moisture. The walls are also insulated – at least 50 centimeters above the water mark.
For drop wells
Drop wells allow for the reduction of pipe depth in some pipeline sections, which lowers the amount of excavation work required and, ultimately, the system’s cost. These kinds of wells dampen the flow rate, which keeps the pipeline from experiencing a water hammer.
Only in cases where the discrepancies and pipe diameters are less than 50 and 60 centimeters, is it feasible to forego installing a damper well. The drain in this case is located in the inspection well.
- All parameters of the designed drop wells directly depend on the height of the difference and the diameter of the pipeline. For differences of up to 6 meters, the well is made in the form of a riser with a diameter corresponding to the cross-section of the supply pipe or more.
- A receiving funnel is made above the riser, in the stilling zone – a pit with a base, which is reinforced with a metal plate. For risers with a diameter of up to 30 centimeters, a guide elbow is made instead of a pit.
- For storm sewers, at differences of up to a meter, drainage wells with water-stilling grates/beams are provided (their number depends on the difference in marks).
It is necessary to become familiar with the specific requirements before beginning the design and implementation of work for septic tanks and storm drains.
Modern infrastructure relies heavily on reinforced concrete wells, which provide dependable and long-lasting solutions for a range of requirements. These wells offer sewage systems a strong, leak-proof environment that is necessary for efficient wastewater management.
