The device of the fence from the Spunt
According to the construction standards and rules (SNiP) currently in Russia, the fence of the walls of the pit must be carried out with relatively “small” depths. The fencing device is required when the foundation depth exceeds 1.25 meters in the case of sandy and other “mobile” soils, and even in the case of dense soils - from a depth of 2 meters.
Such a requirement is a matter of security. The construction site and the people located on it must be reliably protected from the possible sowing of the walls, from penetration into the groundwater site, from possible flooding in cases where work is carried out near reservoirs. The second function is also protective: the fence takes on part of the shock and vibration loads on the soil during a number of work and thereby protects the foundations of close -up buildings.
The pitfish is fenced using slopes: as in this case, the piles are consistently immersed in the soil. In various cases, squints can be wooden, reinforced concrete and metal. Larsen’s special metal bundles are of the greatest strength, the profiles of which are calculated on the greatest resistance to loads in various directions. The technology using pipes as Spunts is also effective and is widely used.
where the shpuntoval fence from pipes is used
The high strength of the pipes and the ability to withstand not only direct pressure, but also the load “on the bend” makes it possible to use them not only to give the pit to the pit of the desired shape and its protection, but also in many other cases.
A peculiar “upgrade” is a pipe squirt welded (STS), or a pipeline. The pipe “turns” into the trumpeter when he receives a couple of special grooves welded along the product. These locks serve for a sequential connection of individual elements into a single design, a sloping circuit, after which a full protective circuit of the necessary configuration is formed.
Castle joints give the design of tightness and provide ample opportunities for its effective use in solving a variety of construction problems:
- Strengthening slopes and embankments, including embankments of railways and roads.
- Strengthening the coastline as an alternative solution to measures to lower the water level.
- The use of hydraulic facilities, berths, docks and gateways.
- Protection of underground communications from groundwater.
- Creation of hermetic reservoirs for industrial waste, the construction of treatment facilities, landfills.
The advantages of a shopant fence from pipes
The rogue fence from pipes has maximum stability among all squire structures. Which gives an additional opportunity to use it as a constant formwork.
Tightness allows you to use in places with a risk of flooding.
The ability to give additional strength of the entire structure, for which enhancing steel elements or concreting can be placed in the pipe cavity.
Universality: Shpuntovo fencing from pipes can be installed in any categories of soils. Various installation technologies, for example, vibration load, make it possible to install in “constrained circumstances”, for example, in dense urban development.
The possibility of repeated use. After completion of the work, the pipes are extracted from the ground, the “turnover cycle” is up to 10 or more times.
The use of pipes of various diameters for fencing the pit
Modern computer modeling technologies allow you to accurately calculate the strength characteristics of the shopant fence and choose the necessary length and diameter of the products for its formation. Complete compliance with the requirements set in the project makes the use of shpunto structures not only effective, but also economically justified.
That is why such technologies are actively used throughout the country, including areas with the most difficult conditions for building.
Zagorsky Pipe Plant is actively increasing the power of the trumpet, the closest goal of the enterprise - & nbsp; The outload of 100 & nbsp; 000 tons of sloppy pipes per year. According to consumers orders, the metallurgists near Moscow ship their own outdoor pipes with a diameter of 530 to 1420 mm and with a wall thickness of 8 to 35 mm, equipped with castle joints of both Russian and foreign manufacturers. The products of the Zagorsky Pipe Plant are fully consistent with GOST R 52664-2010, which regulates the production and use of a trumpet in the territory of the Russian Federation.
