Shpunt it that? Areas of use

Construction work below levelsoil, require its additional strengthening for protection from water or other mechanical interference. This is especially true for loose lands, which are unstable on their own.

The construction of the building begins with a pit. To prevent the destruction of nearby buildings, the relief of the surface of the ground and the landscape, additional reinforcement of the excavation using Larsen's tongue is used.

Definition

Shpunt is a metal construction of a boxsections with linear locks along the edges. When immersed in the ground, the elements are fixed together by means of grooves on the structure. As a result, a continuous continuous canvas is formed.

Larssen L5 pile is made of steelincreased strength in order to easily transfer the immersion in hard soil. Depending on the load on the construction, piles of 15 to 23 mm thick are used. With the correct installation, the construction restrains the movement of ground and underground water, which gives an advantage in construction.

Dips from polymers

For the production of piles, not onlysteel, but also high-strength polymers - polyvinyl chloride and fiberglass. Despite the increased degree of brittleness in comparison with the classical tongue piles made of metal, polymeric ones have a more budgeted cost.

The advantage of polymers is resistance to corrosion. Due to this they are often used to strengthen terraces, coastlines, slopes. Used for the construction of small buildings.

Application area

A dowel is a design that has severalvarieties, of which metal and polymer are most often used. Depending on the characteristics of the material and soil, such elements are used in such cases:

• strengthening the shoreline of water bodies;
• the construction of bridge supports and other hydraulic structures;
• strengthening foundation pits during the construction of large buildings;
• protection of the foundation from groundwater;
• Fencing of a specific area of ​​the soil from landslides.

The dowel creates a sealed space thatrestrains the natural movement of soil and groundwater. In the water zone, it is possible to create a ring from which water is completely pumped out for the construction work.

Installation technique

Shpunt is a kind of pile that sinksin the ground with the help of special construction equipment. Clogging of such elements is carried out in the ground by mechanical action on the upper part of the structure.

Construction techniques create vibrations or tremors,which softly pile up the pile in the soil. At the same time, for small designs, there are handholds for piercing dowels. The choice of the installation method is determined by the characteristics of the soil. So, in the soil, which contains a large number of stones or other hard inclusions, extremely strong metal structures are installed.

Since the tongue is a pile, the assembly begins withfixing the element in an upright position. To facilitate the installation and movement of the pile in the soil, the grooves for the fasteners are treated with a thick layer of lubricant. When installing piles in places with a high level of groundwater, the seams between the elements of the structure are further sealed with silicone-based compounds. For polymer piles, additional lubrication is not required in most cases.

To limit the impact on surrounding buildings, the following measures are taken:

• reduction of hammer impact force;
• Drilling a well for each individual element of the structure;
• reduction in the number of tongues slaughtered simultaneously;
• use of immersion lubricants.

This takes into account the condition of all buildings within a radius of 20 m from the construction site.
