Embodiment 1

[0039] Refer to attached figure 1 Shown is the anchor cable-reinforced soil combined soil retaining member of this embodiment, including foundation 1, I-shaped column 2, flat wall module 3, steel bar connector 4, geogrid 5, anchor rod 6, filler 7 , drain channel 8, anchor hole 9. The drainage channel 8 can be provided with a reasonable shape and size as required, and is not limited to a strip channel. refer to Figure 2-Figure 3 , the I-shaped column 2 is clamped and embedded on the foundation 1, and the flat wall module 3 is inserted into the flange of the adjacent I-shaped column 2, referring to Figure 4-Figure 5 , the back of the flat wall module 3 has a steel connector 4, and a drainage channel 8 is arranged on the wall; the steel connector 4 is an "L" steel member, and a gap is formed between the steel connector 4 and the flat wall module 3 One end of the geogrid 5 is sleeved on the reinforcement connector 4 and stuck in the gap, so that the reinforcement connector 4 ...

Embodiment 2

[0050] In this embodiment, the main structure is the same as that of Embodiment 1, the difference is that the clamping material is a rib-type geogrid, refer to Figure 7 As shown, when the flat wall module 3 is connected with the ribs 11, the ribs 11 can be tied to a horizontal steel bar 10 first, and then the horizontal steel bar 10 can be inserted into a row of "L" shaped steel bars to embed in the gap .

[0051] Concrete construction steps are in the reinforced soil construction process of step 4 in embodiment 1, when the reinforcement material embedded in the back of the wall panel is the rib band 11, the rib band 11 can be bound on a horizontal steel bar 10 earlier, Insert the horizontal steel bar 10 bound with the rib band 11 into the "L" shaped steel bar member. When the soil subsides, the tendon band 11 can move downward along the "L" shaped reinforcement member, which effectively reduces the damage of the reinforcement due to the settlement of the slope.

Abstract

The invention discloses an anchor cable-reinforced soil composite soil retaining component and a construction method thereof, belonging to the technical field of slope support; comprising a column and a wall module, the column is provided with a slot, and the wall module is inserted on both sides In the slot of the column; the inner surface of the wall module is provided with a connecting member, and a gap is formed between the connecting member and the wall module. One end of the reinforcing material is sleeved on the connecting member and stuck in the gap. Filling is arranged between them; when the soil subsides, the reinforced material can move down along the connecting member; the invention significantly improves the bearing capacity and deformation resistance of the slope, and solves the problem that the reinforced material is easily damaged in the existing connecting structure The problem is applicable to a variety of geological situations.

Description

technical field [0001] The invention belongs to the technical field of slope support, and in particular relates to an anchor cable-reinforced soil composite retaining component and a construction method thereof. Background technique [0002] The prestressed anchor cable structure refers to the combination of retaining wall and prestressed anchor cable, which can be used separately, in a certain way, and the support structure is formed through the interaction of the anchor cable, retaining wall and slope rock and soil. Jointly bear the rock-soil pressure generated by the landslide thrust or the unloading and relaxation of the slope, so that the slope is in a stable state. Because the prestress can be applied in the anchor cable in advance, the prestressed anchor cable support structure can actively control the relaxation and deformation of the slope. The prestress of the anchor cable makes the unstable sliding mass in a three-dimensional stress state of high confining pressu...
