Problems solved by technology

[0004] The purpose of the present invention is to provide a simple structure, convenient construction, capable of resisting huge landslide thrust, solving the problem of uneven internal force and deformation of the front and rear rows of piles, and giving full play to the anti-sliding of the front and rear rows as much as possible. The anti-slide ability of piles can also save materials, improve construction efficiency, and effectively reduce the cost of landslide treatment. Double-row long-short combination anti-slide piles

Embodiment Construction

[0020] Below by example, the specific implementation manner of this patent is described in further detail.

[0021] like figure 1 As shown, a double-row combination of long and short anti-slide piles, the anti-slide piles include a front row of anti-slide piles 1 and a rear row of anti-slide piles 2, the landslide includes a landslide bed 3 and a sliding surface 4 and a landslide body 5 on the landslide bed. There is a certain distance between the front and rear anti-slide piles, generally 2-5h (h is the longitudinal height of the anti-slide pile section) to increase its lateral stiffness. The rear row of anti-slide piles 2 adopts buried anti-slide piles (that is, the pile tops are buried below the landslide ground) to reduce the landslide thrust borne by the rear row of piles and increase the burden of the front row of anti-slide piles 1. The anti-slide pile 1 in the front row adopts a full-length anti-slide pile (that is, the anti-slide pile whose pile top is located near t...

Abstract

A double-row long-short combined landslide-resistant pile comprises a front-row landslide-resistant pile body and a rear-row landslide-resistant pile body and is characterized in that the front-row landslide-resistant pile body is a full-length type landslide-resistant pile, the rear-row landslide-resistant pile body is a buried landslide-resistant pile, the length of the load-bearing section of the rear-row pile body is reduced to reduce the landslide thrust borne by the rear-row landslide-resistant pile body, and the landslide thrust borne by the front-row landslide-resistant pile body is increased. Stress and deformation of the front-row landslide-resistant pile body and the rear-row landslide-resistant pile body are adjusted, the problem of uneven stress and deformation of the front-row landslide-resistant pile body and the rear-row landslide-resistant pile body is solved, and landslide-resistant effects of the landslide-resistant can be brought into play. In addition, the arrangement form of dense middle and sparse two sides allows the landslide-resistant piles on two sides a landslide mass are well brought into play.

Description

technical field [0001] The invention relates to a double-row long-short combination anti-slide pile. Background technique [0002] Landslides are a common geological disaster in mountainous and hilly areas of our country. Landslide disasters often have a serious impact on industrial and agricultural production and national economic construction, and also cause serious losses to the lives and properties of the people. In countries with serious landslide disasters in the world, such as the United States, Japan, Italy, India, China, etc., the losses caused by landslides are more than 1 billion US dollars every year. [0003] Anti-slide piles are one of the main engineering measures to control landslide disasters. With the rapid development of economic construction, more and more deep and large landslides are encountered in actual engineering, and single-row anti-slide piles often cannot provide sufficient anti-slide force. Double-row anti-sliding piles have the advantages of ...
