Embodiment Construction

[0030] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0031] Refer to attached Figure 1-Figure 2 Shown is the hybrid reinforced soil retaining wall of the present invention, including ordinary wall panels 1, prestressed wall panels 2, wall panel foundations 3, unbonded prestressed tendons 4, side pressure plates 5, geogrids 6, and fillers 7 . One end of the unbonded prestressed tendon 4 is connected to the side pressure plate 5 embedded in the filler 7 , and the other end is anchored to the prestressed wall panel 2 after being stretched by the anchor 8 . Refer to attached Figure 3-Figure 4 As shown, the back of the prestressed wall panel 2 has horizontal and vertical ribs, and an inwardly recessed anchor hole is left at the intersection of the horizontal and vertical ribs; refer to the attached Figure 5-Figure 6 As shown, there is no rib set on the back of the ordinary wall panel 1, and the connectin...

Abstract

The invention discloses a mixed reinforced retaining wall. The mixed reinforced retaining wall comprises an ordinary wall panel, a prestressed wall panel, a wall panel base, non-bonding prestressed tendons, side pressing plates, geogrids and filler, wherein the ordinary wall panel and the prestressed wall panel are supported on the wall panel base; the prestressed wall panel is connected with the non-bonding prestressed tendons; the ordinary wall panel is connected with the grogrids; one or more grogrids are arranged between the two vertical non-bonding prestressed tendons; one ends of the non-bonding prestressed tendons are connected with the side pressing plates; and the other ends of the non-bonding prestressed tendons are stretched and anchored on the prestressed wall panel. According to the mixed reinforced retaining wall, a traditional reinforced soil technology is combined with a non-bonding prestressed reinforcement technology, the filler is passively restrained by reinforced soil fraction through the traditional reinforced soil technology, the active restraint strengthening action, of the non-bonding prestressed reinforcement technology, on the filler is exerted as well, economy of the non-bonding prestressed reinforcement technology is improved, and construction difficulty of the non-bonding prestressed reinforcement technology is reduced as well.

Description

technical field [0001] The patent of the invention relates to the field of retaining walls, in particular to a hybrid reinforced retaining wall. Background technique [0002] Unbonded prestressed reinforcement technology is an efficient geotechnical reinforcement technology. This technology actively squeezes the filler to form a compression zone through the tension of the prestressed tendon in the main force-bearing part. The filler in this compression zone is in the triaxial The state of compressive stress increases the shear strength of the filler, improves the internal stability of the retaining wall, and reduces soil deformation. Compared with ordinary reinforced soil technology, the use of this geotechnical reinforcement technology can further reduce the horizontal deformation and vertical deformation of the retaining wall, and can control and adjust the prestress level according to actual needs, and can be supplemented during the construction process. Tension reduces ...
