Build houses, shopping malls are being built, bridges constructed pavilions. But very often we can see and a construction site.
City below, as the roots of the forest, just entwined underground utilities: collectors, heating, sewerage, thermal camera, the whole river and underground drains, dressed in a pipe.
In this article, we will focus on the most frequently occurring concrete for the construction of underground communications:
- Rings wells (or another wall of the ring).
It may seem strange why so many wells in the city? People for a long time enjoyed running water, filters, and urban water leaves much to be desired. All these wells are viewing, they are designed for running specialists to thermal mechanical equipment in underground teplokamerah to adjust and repair. Build drinking wells from concrete rings is also possible, but it is better to do it in an ecologically clean areas.
2. Trays of heating serve as casing, which protects the pipe. They are installed in three ways: bottom down, on top of the floor slab is placed, upside down and bottom set bottom plate (it has a powerful reinforcement) or, if the pipes of very large diameter to establish a other. Trays of heating are not intended for the organization of drainage, with the exception of Trays brand LK.
3. Sometimes you can see that's such an interesting structure:
This so-called dobornye trays. They have the same functions and features as conventional trays of heating mains, but much shorter. They are used on non-linear sections.
Twists and turns of heating systems (also referred to as compensators) often do not due to the nature of the landscape, but and that due to temperature variations (and flows through the pipes often boiling) within the lengthened pipe norm.
4. Angles of rotation sometimes draped foundation blocks FBS.
From block basement walls are also often spread the wall of heating chambers.
5.Teplovuyu camera on top of a special cover plate teplokamery overlap. Such plates are often holes from two to four, which are closed with iron hatches with vandal-proof locks. Hole again designed to penetrate repairmen in the event of an accident, and hatches prevent the penetration of the curious.
6. For the organization of the underground drainage easier to use concrete pipe spigot TB.
7. If the drain or discharge is a big load (roads, railways) use the more powerful links in HCC, HSC and RFP.
8. What is it?
This communication wells, they no otnoshniya to the pipe network and collectors do not have. They placed the equipment for underground telephone lines. Telephone wells also have an inspection hatch. Learn more about these concrete products can be found here.
9. These small plates are called a booster cushion. They are placed on the bottom of the pan and have them directly to the pipe rests.
10.
This channel plates, ie slabs trays. If the plates are marked:
- P - This plate cover of the brand A tray
- PT - floor slab for the brand LC tray
- AP - bottom plate for the brand LC tray
These boards are also flashings, i.e. short (they are placed on the non-linearities), angular (RC PTU) may be produced with holes.
Perhaps our article will not open new horizons for professional builders, but satisfy the curiosity of the townspeople accidentally looked into the trench dug up, will help.
Underground utilities are not visible, but a lot depends on them: the heat in their homes, water, working toilet, communications, that is to say almost anything.
