W-shaped high-capacity anti-slip structure and construction method

Abstract

The invention discloses a w-shaped high-capacity anti-slip structure and a construction method, and aims to greatly improve the anti-slip capacity of an anti-slip pile and reduce the risk of landslidegeneration. The structure comprises anti-sliding bodies longitudinally and transversely arranged in rows at intervals in the sliding direction of the sliding bodies, each anti-sliding body comprisesanti-sliding piles built on the lower portion of a construction well, the anti-sliding piles vertically extend by a certain height in sliding bodies and a sliding bed near a sliding belt, and the anti-sliding piles in every two adjacent rows of anti-sliding bodies are arranged on a plane in a staggered mode. Connecting beams which are fixedly connected with the anti-sliding piles and apply prestress to the anti-sliding piles are arranged between the anti-sliding piles which are adjacent up and down in the slide bodies to form a three-dimensional integral anti-sliding structure. A three-dimensional water guiding and drainage system is constructed at the upper part of the construction well and adjacent to the sliding bodies, and groundwater and downward seepage water in the sliding bodies are collected and drained out of the ground.

Description

technical field [0001] The invention relates to a large-capacity anti-slip structure in civil engineering, in particular to a w-shaped large-capacity anti-slip structure and a construction method. Background technique [0002] Landslides will pose a great threat to engineering safety. Using reasonable engineering measures to control landslides is an important disaster control technology in geotechnical engineering. The most effective traditional engineering measures to deal with landslides are anti-slide piles and their composite structures. His The principle is mainly to use the lateral resistance of the anti-slide piles to resist the landslide thrust caused by the sliding of the sliding mass to ensure the stability of the sliding mass. However, traditional anti-slide piles still have disadvantages, such as the pile cross-section is too large, a large pile body section is required to resist landslide thrust, and even several rows of piles are required to support at the same...

Problems solved by technology

However, traditional anti-slide piles still have disadvantages, such as the pile cross-section is too large, a large pile body section is required to resist landslide thrust, and even several rows of piles are required to support at the same time, resulting in high cost and long construction period; The force is uneven, and each pile is set independently. When the sliding body slides, it is very likely that the overall damage will be caused by local damage, and the entire anti-slide pile structure will fail.

For example, the traditional anti-slide piles are transformed into "gate" piles, chair piles, bent piles, and h-shaped piles through connecting beams. Did not get substantial savings, and the difficulty of construction increased
