Sheet piling works

The use of metal sheet piles

Sheet piles (or dowels) - a metal piles for the device walling or impervious curtains.

The solid wall, built of closely adjacent to each other sheet piles, called tongue and groove or near the fence. To make such a connection structure has a solid and reliable, each element has on the side of the locks, whereby strong adhesion occurs.

The sheet metal piles may be different profiles: flat, Z-shaped, trough-shaped or executed according to the "Larsen". Flat dowels are used in the design of impervious curtain, Z- and trough - in the construction of retaining walls, bridges, barrier installations, berths, sluices. Industrial metal sheet piles can be applied repeatedly as fencing of trenches, pits, trenches.

Before you immerse tongue, you must check its straightness, integrity of locks, to get rid of sagging, and the top of the cut a hole through it to connect the sheet pile with vibrator lanyard. If necessary, you need to make and the angular tongue.

Methods dive tongue and recommendations for their application

The tongue may be immersed in the following ways:

• •  stroke (pile-driving hammers);
• •  vibratory (by means of the vibrator);
• •  static indentation piles into the ground;
• •  vibrovdavlivanie combined (vibration method with the addition of the weight load of the machine itself).

One or another way to dive is applicable in different cases (there are practical recommendations for the use of various methods in specific circumstances).

Thus, the impact method is appropriate for any soil; vibro - in the case of non-cohesive sandy soils or sandy loam type; vibrovdavlivanie - for clay soil softness or tekucheplastichnogo type fluid-loam; and indentation - when immersed in a fluid such as clay soil.

Vibrating way of piling

Using this method, the tongue dipped into the ground by vibration, which creates a special machine. Feeling strong vibrations pile overcomes the frictional force on its side surface and resistance at its tip, leaving the soil to the desired depth. Are taken into account the oscillation amplitude vibratory and weight - they should provoke the irreversible destruction of the soil structure.

Typically vibration method is used when dealing with water-saturated soil.

If the ground is dense and malovlazhnogo, you must have the leading well.

When submerged the tongue to a great depth, and insufficient power vibrator, soil pre tempted water jet power showers.

vibro method is very ergonomic in the use of space: for enough space for the installation of the crane or excavator.

Movax vibrator based excavator produces lateral grip and piles can move it all over the construction site to lift, load and extract the metal tongue. In the case of complex soil and sheet piling device to a depth of 15m, is used mounted pogruzhateli more power. Work also can be carried out with the boats.

Sheet piling or sheet pile wall - a watertight solid wall formed sheet piles (Larssen sheet piling, sheet piling PVC ECP tongue, tongue Arcelor, etc.). Sheet pile wall keeps the soil from collapsing in the construction of various building structures, defends during excavation of ground water. The construction of sheet piling is carried out by immersion of the tongue.
