Abstract

A double-row anti-slide pile support structure in the shape of a character, including a front row of anti-slide piles and a rear row of anti-slide piles. Lian Liang. Its advantages are: the double rows of anti-slide piles are all embedded in the stable rock and soil body, making full use of the shape of the piles, and setting the herringbone truss connecting beam at the end of the cantilever to bear the horizontal thrust and reduce the bending moment. The purpose is to control the horizontal displacement better, the ability to bear the landslide thrust is greatly improved, and it is more economical and reasonable. The support structure improves the stress and deformation state of the cantilever piles, effectively solves the problem that a single row of piles cannot resist excessive landslide thrust, and can also effectively solve the problem of the angle between the landslide thrust direction and the slope surface of the empty slope. It is especially suitable for large-scale landslide control projects and high slope support projects.

Description

Pin-shaped double-row anti-slide pile retaining structure

technical field

The utility model relates to an anti-sliding retaining structure, in particular to an anti-sliding retaining structure used for large-scale landslide treatment projects and high slope support projects.

Background technique

High slope support and landslide control have always been a major problem in the engineering field. Often in mining, road construction, bridge building, and mountain building leveling, complex strata may be encountered, and a large number of high Slope cutting and artificial filling of slopes will greatly change the original topography and landform, breaking the original self-balance, and will cause a certain scale of sliding, posing a great threat to people's lives and property. Therefore, it is necessary to carry out reliable anti-skid support.

For large-scale landslide control projects and high slope support projects, we often use anti-slide piles, anchor cables, anti-slide piles + anchors, anti-slide piles + braces and other measures. Single-row anti-slide piles and multi-row anti-slide piles can control large-scale landslides, and multi-row anti-slide piles can resist landslide thrust in stages. They have the disadvantages of unclear force on the front and rear piles and high cost. The measure of anti-sliding piles + braces is more economical, but its disadvantage is that the braces should be located on stable ground, and when the (potential) sliding surface is deep, the braces are often difficult to construct. Anchor cable is an economical solution, but its construction is very difficult, it is difficult to form holes in complex strata, and the construction quality is difficult to control, and its long-term reinforcement effect is often difficult to guarantee due to the stress relaxation effect. In addition, the anchoring formation of the anchor cable is more restricted.

Contents of the invention

The utility model provides an anti-skid retaining structure, which can effectively solve the above-mentioned problems in the prior art.

The utility model is a double-row anti-sliding pile support structure in the shape of a character, including a front row of anti-slide piles and a rear row of anti-slide piles. concrete trusses,

The two ends of the herringbone truss reinforced concrete truss connecting beam are arranged on the pile tops of the front and rear rows of anti-sliding piles; or one end is on the pile top and the other end is on the bottom of the piles.

The pin-shaped double-row anti-slide pile retaining structure is realized in this way:

⑴The front row of anti-slide piles and the rear row of anti-slide piles shall be constructed first, and the piles shall be arranged in a font style;

(2) The front row of anti-slide piles and the rear row of anti-slide piles are embedded in a stable rock and soil layer, that is, a stable stratum below the (potential) sliding surface;

(3) Chisel off the pile top laitance of the front row anti-slide piles and the rear row anti-slide piles until the design pile top elevation;

⑷Reinforced concrete lock beams are installed on the tops of the front row of anti-slide piles and the rear row of anti-slide piles, and herringbone reinforced concrete connecting beams are arranged between the tops of the front and rear rows of piles to form a herringbone truss connecting beam;

(5) Herringbone truss beams can be buried below the ground.

The beneficial effects of the utility model are as follows: the double rows of anti-slide piles are embedded in the stable rock and soil body, and the font layout of the piles is fully utilized. The purpose is to better control the horizontal displacement, and the ability to bear the thrust of the landslide is greatly improved, and it is more economical and reasonable. The support structure improves the stress and deformation state of the cantilever piles, effectively solves the problem that a single row of piles cannot resist excessive landslide thrust, and can also effectively solve the problem of the angle between the landslide thrust direction and the slope surface of the empty slope. The process is simple, and the spatial three-dimensional structure layout is reasonable and stable, and it is especially suitable for large-scale landslide control projects and high slope support projects.
