Embodiment 1

[0029] see image 3 and Figure 4 , an anti-skid corrugated steel pipe pile, comprising two rows of corrugated steel pipe groups arranged in the sliding direction of expansive rock and soil body 1, each row of corrugated steel pipe groups is composed of a number of corrugated steel pipes 3 arranged with a certain gap, each row of corrugated steel pipes The number of corrugated steel pipes 3 in the group is determined according to the length of the anti-skid surface. The corrugated steel pipes 3 of the two rows of corrugated steel pipe groups are staggered and inserted, that is, the gap between the corrugated steel pipes in the first row and the corrugated steel pipes in the second row is facing each other. The lower part of each corrugated steel pipe is buried in the sliding bed 2, and the corrugated steel pipe 3 is filled with backfill, which is concrete mortar 4 in this embodiment.

[0030] In this embodiment, the corrugated steel pipes 3 of the single-row corrugated steel ...

Embodiment 2

[0033] see Figure 5 , an anti-slip corrugated steel pipe pile, comprising three rows of corrugated steel pipe groups arranged in the sliding direction of expansive rock and soil, each row of corrugated steel pipe groups is composed of a number of corrugated steel pipes 3 arranged at certain intervals, each row of corrugated steel pipe groups The number of corrugated steel pipes 3 in the center depends on the length of the anti-slip surface. The corrugated steel pipes 3 of the three-row corrugated steel pipe group are staggered and inserted in pairs, that is, the gap between the corrugated steel pipes 3 in the first row and the corrugated steel pipes 3 in the second row Facingly, the gap between the corrugated steel pipes 3 of the second row and the corrugated steel pipes 3 of the third row is directly opposite, and the lower part of each corrugated steel pipe is embedded in the sliding bed, and the corrugated steel pipes are filled with backfill. In this embodiment, the backfi...

Embodiment 3

[0037] An anti-skid corrugated steel pipe pile, including four rows of corrugated steel pipe groups arranged in the sliding direction of expansive rock and soil, each row of corrugated steel pipe groups is composed of a number of corrugated steel pipes arranged at certain intervals, and each row of corrugated steel pipe groups The number of corrugated steel pipes depends on the length of the anti-skid surface. The corrugated steel pipes of the four-row corrugated steel pipe group are staggered and inserted in pairs, that is, the gap between the corrugated steel pipes in the first row and the corrugated steel pipes in the second row is directly opposite, and the corrugated steel pipes in the second row The gap between the corrugated steel pipes in the third row and the corrugated steel pipes in the third row is in direct alignment with the gap between the corrugated steel pipes in the third row and the corrugated steel pipes in the fourth row. In this embodiment, the backfill is...

Abstract

The invention relates to an anti-sliding corrugated steel pipe pile. The anti-sliding corrugated steel pipe pile comprises a plurality of rows of corrugated steel pipe sets arranged in the sliding direction of an expansive rock-soil body, each row of corrugated steel pipe sets is formed by arranging a plurality of corrugated steel pipes at certain intervals, the adjacent corrugated steel pipe sets are staggered, the corrugated steel pipes of one row of corrugated steel pipe sets are opposite to the gaps of the other row of corrugated steel pipe sets, the lower part of each corrugated steel pipe is embedded in a sliding bed, and the corrugated steel pipes are filled with backfill. The multiple rows of corrugated steel pipe sets are arranged in an inserted mode to form the anti-landslide three-dimensional array, the filler is poured into the corrugated steel pipes to enable the corrugated steel pipes to be extremely firm, and compared with common steel pipe piles, the anti-deformation capacity is greatly improved; and the stress performance of the whole anti-landslide array is good, and the anti-sliding capacity and the rockfall impact resistance of the sections prone to landsliding are greatly improved.

Description

technical field [0001] The invention relates to the field of landslide prevention and control, in particular to an anti-slide corrugated steel pipe pile. Background technique [0002] Landslide refers to a certain part of the rock and soil on the slope of the mountain under the action of gravity (including the gravity of the rock and soil itself and the dynamic and static pressure of groundwater), which produces shear displacement along a certain weak structural surface (band) and moves downward to the slope as a whole. effects and phenomena. Commonly known as "Zoushan", "Collapsed Mountain", "Ground Slip", "Soil Slip", etc., it is one of the common geological disasters. [0003] In areas with many mountainous areas, after the construction of railways or roads, various landslide disasters such as collapse, cracking, and misalignment of retaining walls are prone to occur, especially mudslides caused by earthquakes and heavy rains. Therefore, rapid rescue has become a top pri...
