Landslide design

 

The invention relates to the construction and can be used for stabilization of landslide-prone slopes. Landslide design includes a bored pile, combine grillage, connected by an anchor in sustainable soil slope. What's new is that the trunks have piles within the gradient layer team box with the unfolding toward the movement of soil by wing restricting the passage between the piles. Technical result provided by the invention is to reduce material consumption and improve the efficiency of anti-design. 6 Il.

The invention relates to the construction, in particular, can be used to stabilize the landslide slopes.

Known landslide structures including a series of bored piles, United gratings (Braslavsky C. D. Landslide designs on the roads. M.: Transport, 1985, S. 162, 163). The disadvantage of these designs is the large consumption when the device multilayered structures.

In some types of landslides can be identified in the cross-section of the gradient layer, usually clayey soil makoplasty or fluid consistency at which the offset is Acting, 1977, S. 248, Fig. 12.5). The retention of such landslides depends on interaction design with gradient layer.

Closest to the invention is anti-design, including a bored pile, combine grillage, connected by an anchor in sustainable soil slope (Braslavsky C. D. Landslide designs on the roads. M.: Transport, 1985, S. 235, Fig.7.7).

The disadvantage of this design is that the distance between the piles in the row must be determined from the condition forcing weak ground between them. Given the significant difference in the mobility of the soil gradient and passive layers, this distance can be increased if the increase of the piles within the weak layer.

The task of the invention is to reduce material consumption and increasing the efficiency of anti-design.

The problem is solved due to the fact that landslide design, including bored piles, combined grillage, connected by an anchor in sustainable soil slope is within the gradient layer team box with the unfolding toward the movement of soil by wing restricting the passage between the piles.

The technical result image

The invention is illustrated by drawings, where Fig.1 shows a landslide design, side view in cross section along the landslide; Fig.2 is a plan of the landslide; Fig.3 - team insert in the assembled condition of Fig.4 is a view in plan; Fig.5 - team box in the expanded form; Fig.6 - same view in the plan.

In the landslide gradient 1 and passive 2 layers will mix on sustainable soil 3, which has a bored pile 4, the combined grillage 5 held by the anchor device 6 in the ground 3. The trunks of the piles 4 are within the gradient layer 1 team box with pull-down towards the ground movement of the wing 7, rotating around the axes 8 and fixed by the tie rod 9. The wing 7 are located between the disks 10 and 11, located on the subtle end of the barrel 12 piles 4.

Landslide structure erected in the following sequence: drill a well to the calculated depth, then she lowered the lower part of the reinforcing cage with section 13, which must enter into the subtle portion 12 of the barrel, put the team box with the unfolding wing 7, install the upper part of the reinforcing cage and through bitonality pipe concreted shaft bored piles 4, uniting its parts.

Landslide structure, which includes a bored pile, combine grillage, connected by an anchor in sustainable soil slope, characterized in that the trunks have piles within the gradient layer team box with the unfolding toward the movement of soil by wing restricting the passage between the piles.
