Description

The invention relates to the construction, in particular to the construction of deep piers made of shells.

Known sva, including a hollow trunk with a rigidly fixed diaphragm in the form of vertical partitions in the lower part of the trunk I ...

The disadvantage of this pile is the difficulty of immersing it to a great depth due to the great resistance to immersion caused by premature soil compaction in the internal cavity of the pile.

Closest to the proposed technical essence and the achieved result is a pile comprising a hollow barrel and a horizontal diaphragm 2 placed in its cavity.

This pile is characterized by a low bearing capacity and difficult to immerse it in the ground.

The aim of the invention is to thrust the bearing capacity and facilitate immersion.

This goal is achieved by the fact that the shaft, including the hollow barrel and the horizontal diaphragm placed in its cavity, is equipped with traction and the diaphragm is made with through-shaped anals, in which are installed the tightening devices, and each lower end is rigidly attached to the lower parts of the hollow shaft and passed through the appropriate jig in the diaphragm.

Figure 1 shows a diagram of the pile in the beginning of the dive, a longitudinal section; Fig. 2 shows the same after immersion; on fig.Z - section aa in figure 2; Fig. 4 - mount knot gi to the diaphragm, a longitudinal section; Fig. 5 is a plan view of the mount.

Sva includes a hollow barrel 1 with a knife part 2 and placed in its

The flatness is horizontal diaphragm 3. To the knife part 2 around the perimeter there is a rigidly fixed clamp 4 of the cable with anticorrosive protection or a reinforcing rod.

The diaphragm is made with scood channels 5, in which clamping devices 6 are installed.

The other end of the cable 4 is freely passed through the through channel 5 diaphragm | 3 and 3, correspondingly to the clamping device 6, made, for example, in the form of a removable clamp collet in the diaphragm 3.

Sva works as follows. .

When the pile is immersed by well-known structures (not pokayy), the diaphragm 3 is located in the internal cavity of the barrel 1 and slides along tam 4, resting on the ground and not impede immersion. After the pile is deepened to a height somewhat shallower than the depth of its project foundation, for example, 1-2 meters by known methods, for example, by applying rods (not shown) or directly on the site, the ends of g 4 are clamped to the diaphragm 3 by installing them in the through channels 5. During Further diving of the pile, the diaphragm 3 also sinks and compresses the soil in the area of the pile base to form a soil core.

The proposed pile can be immersed, especially in weak soils, to a considerable depth without first excavating the soil from under its base, which provides an increase in its bearing capacity by 1.3-1.5 times, and the implementation of a moving diaphragm many times reduces the resistance force when diving piles, chuo reduces the time for its immersion.
