Abstract

The invention relates to the development of anti-landslide structures and improves the efficiency of / -holding landslides in the zakplasticheskaya-:; gr type. The structure includes racks 1, placed in pairs in a row transverse to the direction of the landslide, and vertical swivel plates 2 fixed to the racks with the help of clamps 4. Each plate is made with a bevel of 30-45 & on the end face facing the landslide, and with a bevel 45-60 - on the other end. In each pair of plates, fixed on the corresponding pair of racks, bevels are turned to each other. When the landslide is moving, the soil exerts pressure on the bevels facing the ends of the plates.

The invention relates to the field of construction and relates to the construction of a rock-and-landslide structure, intended to stabilize a landslide of the non-plastic type.

The aim of the invention is to increase the effectiveness of the retention of landslides of the zoplastic type: Figure 1 shows the anti-landslide EJoe construction, top view; in fig. 2 - the same, front view; fig 3 is the same, ed in the side.

The anti-landslide structure includes pillars 1, placed in pairs across the direction of the landslide, vertical swivel plates 2 A pair of pillars of pillars 1 are fixed in base 3, which is located in stable rocks. Plates are put on racks 1 and fixed on them with the help of clamps 4, the ends of the panels facing the landslide are made obliquely at an angle of 30-45 °, the other ends of the plates are also made with bevels, the angle of which is 45-60 ° , In each pair of racks, the bevels of the plates fixed to them are brought together.

Short trenches are torn off on the landslide body in the I-direction longitudinal to the landslide. A trench 3 is arranged in the trench, in which vertical pillars 1 are buried in a vertical position, ijbie plates 2 are hung on the stand-

When the landslide is moving, the soil exerts pressure on the bevelled ends of the ijUiHT. A horizontal, self-exerting pressure force arises, which

rolls the plates. The reversal continues until the rear ends of the plates are closed. The distance between the pairs of plates is chosen so that after they are fully opened, a continuous wall is formed.

As a result of the use of the landslide construction,

the possibility of holding landslides of the visco-plastic type without trench fragments across the slope, reducing its stability, as well as reducing the volume of earthworks and mounting material consumption, increasing safety and reducing labor costs during the construction of the structure,

Claims (1)
