Anchor pile and method of construction

 

(57) Abstract:

The invention relates to the construction, namely the design of piles constructed in permafrost weak soils. The inventive anchor in the pile, including the trunk with anchor elements on the side surface, the anchoring elements in the form of one or more flexible mesh panels with a length equal to or smaller length of the barrel, each of which is attached at least part of the edge of the trunk and wrapped loosely around him with the formation of the layers. Flexible mesh elements can be attached to a section of the trunk that is located below the active soil layer. In the method of construction of an anchor pile, including the formation of wells, sinking the piles and pinning her to the ground, dive shaft with anchor elements in the form of one or more flexible mesh panels attached to at least part of the edge of the trunk and wrapped loosely around him, performed simultaneously with the rotation around the longitudinal axis in the direction of tightening the panels, and after the dive produce rotation of the shaft in the opposite direction. The present invention allows to increase the load bearing capacity of piles. 2 S. and 1 C. p. F.-ly, 4 Il.

Known pile, including the basis on which successful thickening, increasing in diameter towards the top of the pile [1] the Method of construction of this pile is that the first score in the soil pipe, which is collected by means of a spring from two or more parts, and then fill the pipe with sand and gravel, and then hammer pile slub. During piling sand and gravel are captured and are fond of swelling of piles, surrounding her. The pipe thus narrows or widens, opening at the bottom with a stationary upper end, allowing the pipe to go along with the pile.

The disadvantages of this design of piles and method of its construction is the necessity of special equipment and material for filling pre-formed wells, the complexity of technology and greater complexity.

Closest to the invention is a pile, marajuana in permafrost soil containing the barrel, in which sealed transverse reinforcing rods forming protrusions [2] the Method of construction of this pile includes a preliminary implementation of wells, the installation into the borehole piles, filling the space of the defects of this pile and method of its construction is the need for backfill and compaction of the material, and low bearing capacity due to the small surface freezing of the ground with the rod projections.

The objective of the invention is to increase the bearing capacity of piles by increasing the surface freezing of the ground anchor elements piles and exceptions backfill and compaction of the material during the construction of piles.

For this to anchor the pile, including the trunk with anchor elements on the side surface, the anchoring elements in the form of one or more flexible mesh panels with a length equal to or smaller length of the barrel, each of which is attached at least part of the edge of the trunk and wrapped loosely around him with the formation of the layers.

Flexible mesh panels can be attached to a section of the trunk that is located below the active soil layer.

The objective of the invention is also achieved by the fact that in the method of construction of an anchor pile, including the formation of wells, sinking of the shaft with anchor elements on the side surface and securing it in the ground, put the barrel with the anchoring elements in the form of one or more flexible mesh panels attached to at least part of the edge of the trunk and freely Ober is zivania panels, and after a dive produce rotation of the shaft in the opposite direction.

In Fig.1 shows the proposed anchor pile when you dive it into the ground; Fig.2 section a-a in Fig.1; Fig.3 anchor pile in working condition; Fig.4 section b-B in Fig.3.

Anchor pile includes a barrel 1, a flexible mesh panel 2, which is fixed one end on the pile shaft along its length and several times wrapped loosely around him. Mesh panels 2 may be cut to pieces a and b, and the level of their separation is near the level of seasonal freezing of soil. Part a corresponds to the area of seasonally frozen ground and not attached to the barrel 1 of the piles.

Mesh cloth 2 can also be placed on the length of the shaft or mounted on a part of the length of the barrel (not shown) depending on the initial conditions.

The method of construction of an anchor pile is implemented as follows.

The barrel 1 of the piles with the wrapped around him and mesh panels 2 are immersed in Britanny frozen or weak ground while rotating in the direction of winding of the wire mesh panels 2, while it tightly to the trunk and do not hinder the immersion piles. After mportant direction. While mesh panels 2, raskruchivayas, away from the trunk and take a concentric spatial position (Fig.3). Surrounding the pile soil fills the cells of the grids and the space between the coils.

During the construction of piles in permafrost mesh cloth 2 freeze together with the soil and form a single monolithic system.

In soft soils mesh panels are reinforcing elements.

Performing mesh panels spanned the length of the barrel is designed to eliminate the effects of frost heave due to the fact that the upper part of the mesh of the cloth moves freely along the shaft together with the ground when the bag expands during freezing and sedimentation after thawing.

When the mesh cloth is fixed on only part of the length of the barrel, will significantly increase the anchoring properties of the piles, as during the reverse rotation of the pile loose part of the mesh of the cloth forms a widening conical shape with a larger radius turns, which increases traction.

1. Anchor pile mainly for frozen and weak soils, including the trunk with anchor elements on the side surface, wherein the anchor shaft, each of which is attached at least part of the edge of the trunk and wrapped loosely around him with the formation of the layers.

2. Pile on p. 1, characterized in that the flexible mesh panel attached to the section of the trunk that is located below the active soil layer.

3. The method of construction of an anchor pile, including the formation of wells, sinking of the shaft with anchor elements on the side surface and securing it in the ground, characterized in that immerse the barrel with the anchoring elements in the form of one or more flexible mesh panels attached to at least part of the edge of the trunk and free wrapped around him, and simultaneously by immersing the barrel rotate around the longitudinal axis in the direction of tightening the panels, and after the dive produce rotation of the shaft in the opposite direction.
