The method of construction of an anchor pile in casinopokernews heaving soils

 

(57) Abstract:

Use: in the construction during the construction of pile anchors for fixing in the ground guyed masts, poles of power lines and other structures tower in casinopokernews heaving soils. The essence of the invention: method of construction of an anchor pile in casinopokernews puchinistyh soils, including deep in the soil of the pile shaft and connect it to an anchor thrust, before burying the trunk produce the sensing axis of constructed piles and determine the thickness of the compacted soil layer underlying the active layer, the tip of the pile shaft deepened below the depth of seasonal freezing on the thickness of the underlying active sdoi compacted soil layer, and the depth in the ground of the pile shaft is carried out using the inventory extension, and between the pile top and bottom faces Pei seasonal soil freezing, place the hard permeable diaphragm which is mounted on the bottom of the drilled hole. Technical result provided by the invention is the simplification of the construction of the anchor pile in casinopokernews heaving soils and increase the reliability of protection against rebound when polysilazane pile anchor device for securing a variety of building structures in soils, susceptible to frost heave.

A known method of construction of an anchor pile, including the depth in the ground of the pile shaft and connecting it to the anchor rod.

The disadvantage of this method is the necessity of cutting into the soil Foundation inclined slots for transmission of thrust anchor connected with angerami object.

Object of the invention is the simplification of the construction, as well as improving the reliability of protection against frost heaving, and increased load capacity of an anchor pile.

The problem is solved due to the fact that the method of construction of an anchor pile in casinopokernews heaving soils, including deep in the soil of the pile shaft and connect it to an anchor thrust, before burying the trunk produce the sensing axis of constructed piles and determine the thickness of the compacted soil layer underlying the active layer, the tip of the pile shaft deepened below the depth of seasonal freezing on the thickness of the underlying active layer of a compacted soil layer, which is determined by the results of sensing, and the depth in the ground of the pile shaft is carried out using the inventory extension, which at the time of immersion connect with ogol the disconnection of the anchor rod from the extension and remove it. Up to the depth of the tip of the pile shaft drill hole, the pile shaft is immersed in its bottom, and between the pile top and bottom boundaries of the seasonal soil freezing in the well establish rigid permeable plate or diaphragm.

The technical effect achieved due to these technological features, is the simplification of the construction of the anchor pile in casinopokernews heaving soils, increasing the reliability of the protection from frost heaving and strength retention in the soil against the action of pulling a load.

The effect is achieved through the use of high strength properties of the underlying active layer of compacted soil layer and enhance them using established within this layer rigid plate or diaphragm, as well as through the use of inventory extension connected to the pile top during her dive through the anchor rod.

The construction of the anchor pile in casinopokernews heaving soils in accordance with the proposed method is accomplished by penetration of the pile to the level of the ground surface, connect it with the anchor rod with the inventory extension, and then further distesa from piles and is extracted from the ground, and the free end of the anchor pull connected with angerami object. Before burying piles produced by the sensing axis of constructed piles determine the thickness of the compacted soil layer underlying the active layer.

During the construction of piles in dense or frozen ground to a depth of seasonal freezing pre-drill hole, and the pile immersed in her bottom also using the inventory extension.

In another process variant, the connection of the anchor rod and the extension with the pile may be carried out before its penetration into the soil. In this case, the immersion piles produced from the very beginning together with extension, as with the ground surface and from the bottom of the drilled hole.

To increase the strength of fixing the piles in the soil and enhance its anchor properties on the bottom of a well placed hard permeable diaphragm, made in the form of concrete or metal perforated plate or grating. Freezing heaving layer through the diaphragm exerts pressure on the melted base, which leads to compaction and increase the friction of the thawed soil on the lateral surface of the pile. Reducing the moisture content of thawed soil under freezing layer AFL, the Oia on the lateral surface of the pile. This increases the effort of crushing piles in the surrounding array of soil and increase its bearing capacity.

The proposed method allows to significantly simplify the technology of construction of the anchor piles in casinopokernews heaving soils and to increase the reliability of protection from frost heaving while increasing load capacity.

This is due to the fact that the pile is beyond heaving layer in freezing ground, with enhanced strength properties and tangential heave force acting on the anchor rod, the amount is disproportionately small compared with the crushing strength of the pile in the soil due to the low surface freezing of thrust with the heaving ground.

The proposed method is most effective can be used in the construction of various building structures, angerami in the soil, for example, the relay communication masts, poles of power lines and other objects of the tower type.

1. The method of holding the anchor links in casinopokernews heaving soils, including deep in the soil of the pile shaft and connect it to an anchor thrust, characterized in that before the depth of stolo active layer, the tip of the pile shaft deepened below the depth of seasonal freezing on the thickness of the underlying active layer of a compacted soil layer, and the depth in the ground of the pile shaft is carried out using the inventory extension, which at the time of immersion connect with pile top by means of anchoring thrust, and after reaching the end of stem above the depth shall detach the anchor rod from the extension and remove it.

2. The method according to p. 1, characterized in that to the depth of the tip of the pile shaft drill hole, and the pile shaft is dipped into her bottom.

3. The method according to p. 2, characterized in that after immersion of the pile shaft in a drilled bore between the pile top and the bottom of the active layer are installing a hard permeable plate or diaphragm.
