Problems solved by technology

[0012] Since the current design principles of anti-slide piles do not take into account the characteristic that the soil can form an arch, relative to the entire landslide body, no matter the arrangement of anti-slide piles, the arrangement density, or the strength of each pile are considered individually, and are not considered. It can organically combine the setting method of piles with the natural characteristics of the soil, so the current pile arrangement method has a large amount of work, high treatment cost and low treatment effect

Embodiment Construction

[0023] Fig. 1 is a schematic diagram of the geological structure of the landslide. The sliding belt 1 is located on the sliding bed 2, and the sliding belt slides downward along the sliding surface 3 between it and the sliding bed.

[0024] figure 2 , image 3 Shown is the schematic diagram of pile arrangement of the present invention, pile row 4 is made of several connected single piles, adjacent two rows of piles form a V-shape without apex, the V-shaped opening faces the sliding body direction, and the gap between the two rows of piles is The minimum spacing and included angles match the physical state of the landslide zone. According to the geometric characteristics of the landslide, several groups of V-shaped pile row units can be arranged at appropriate distances.

[0025] Such as Figure 4 Shown is the schematic diagram of the structure of the simulated device for verifying the present invention. The device is an open box with a depth of 10 centimeters. Two sheet pil...

Abstract

The invention discloses a new design method for slope fixing piles. The method uses soil doming theory, the slide resisting piles are arranged with V type, the aperture direction of the V type faces to the slope. The slide resisting force can be upgraded about 20% in the invention, compared with current pile with the same projection area. Many local arc are formed in the slope, though the soil has local deformation, it will be compacted tighter and tighter, thus the local stability if enhanced, and the whole slope is more stable because of the slide resisting piles.

Description

technical field [0001] The invention relates to a method for arranging piles for slope reinforcement, in particular to a method for arranging piles for anchoring landslide bodies. Background technique [0002] Landslides are a common unfavorable geological phenomenon in construction projects. Landslides should be avoided as much as possible in the process of project site selection. Various landslide problems require effective engineering measures to control them. [0003] Setting anti-sliding retaining structures to prevent slope sliding is the most effective treatment method in current engineering, among which anti-sliding piles are the most widely used. The basic anti-slide principle is to set a series of piles at appropriate positions in the landslide zone, these piles pass through the slide zone and enter the lower stable foundation, and use the anchorage section of the piles to prevent the slide of the slope. [0004] Anti-slide piles can be selected in various forms ...
