Abstract

The utility model relates to a soil nail centering structure, 3 centering reinforcing steel bars are arranged on the soil nail at intervals in a circumferential direction at equal intervals, the centering reinforcing steel bars are bent into a Z shape by one reinforcing steel bar and divided into 3 segments, one segment is a supporting segment, the other segment is a binding segment, a transition segment is arranged between the supporting segment and the binding segment, the supporting segment is parallel to the binding segment, two ends of the transition segment are respectively connected with one ends of the supporting segment and the binding segment, and the connection part is a fillet; the binding section is bound and fixed with the soil nail through a steel wire, and the distance between the supporting section and the axis of the soil nail is equal to the radius of the anchor hole of the soil nail. The utility model discloses can avoid causing the welding to hinder to the soil nail to fish tail pore wall when avoiding the soil nail to install in the anchor eye guarantees the centering of soil nail in the anchor eye, guarantees the anchor effect of soil nail.

Description

Soil nail is to well structure
Technical Field
The utility model belongs to excavation supporting construction field relates to an adopt soil nail when consolidating foundation ditch slope, the installation centering structure of soil nail in the anchor eye.
Background
The soil nail support is a technology for reinforcing the side slope by drilling an anchor hole on the side slope of the foundation pit, inserting a soil nail into the anchor hole, and then grouting in the anchor hole to enable the soil nail and the side slope soil body to be consolidated into a whole. When the soil nail is installed in the anchor hole, the soil nail is ideally positioned in the middle of the anchor hole, namely the axis of the soil nail is coincident with the axis of the anchor hole. The current soil nail centering method is to weld 3 centering steel bars on a soil nail at intervals in a circumferential direction, the centering steel bars are perpendicular to the soil nail, and the distance from the axis of the soil nail to the end part of the centering steel bars is equal to the radius of an anchor hole, so that the soil nail can be just positioned at the center of the anchor hole after being inserted into the anchor hole, but the following problems exist: firstly, the end part of the centering steel bar is easy to scratch the hole wall, so that the grouting anchoring effect is influenced; secondly, the centering reinforcing bar welds with the soil nail, can cause the welding to hinder to the soil nail, influences the withdrawal resistance of soil nail.
Disclosure of Invention
The utility model aims at the above-mentioned problem, a novel soil nail centering structure is provided, under the prerequisite of guaranteeing soil nail centering in the anchor eye, the anchor power of guaranteeing the soil nail is not influenced.
The technical scheme of the utility model as follows:
the utility model provides a soil nail is to well structure, every equidistant hoop equidistance sets up 3 centering reinforcing bars on the soil nail, its characterized in that: the centering steel bar is bent into a Z shape by one steel bar and is divided into 3 sections, one section is a supporting section, the other section is a binding section, a transition section is arranged between the supporting section and the binding section, the supporting section is parallel to the binding section, two ends of the transition section are respectively connected with one ends of the supporting section and the binding section, and the joint is a fillet; the binding section is bound and fixed with the soil nail through a steel wire, and the distance between the supporting section and the axis of the soil nail is equal to the radius of the anchor hole of the soil nail.
The utility model discloses can avoid centering reinforcing bar fish tail pore wall to centering reinforcing bar has adopted the ligature connection with the soil nail, has avoided causing the welding to hinder to the soil nail, avoids influencing the anti-pulling force of soil nail, can guarantee soil nail anchor effect, has improved excavation supporting's factor of safety.
Drawings
Fig. 1 is a schematic structural diagram of the present invention;
FIG. 2 is a schematic view of the structure of the centering bars;
fig. 3 is a schematic view of the installation state of the present invention in the anchor hole.
Detailed Description
As shown in fig. 1 and 2, 3 centering steel bars 2 are annularly and equidistantly arranged on a soil nail 1 at certain intervals, each centering steel bar is bent into a Z shape by one steel bar and is divided into 3 sections, one section is a supporting section 21, the other section is a binding section 22, a transition section 23 is arranged between the supporting section and the binding section, the supporting section 21 is parallel to the binding section 22, two ends of the transition section 23 are respectively connected with one end of the supporting section and one end of the binding section, and the joint is a fillet; the binding section 22 and the soil nail 1 are bound and fixed through the steel wire 3, and the distance between the supporting section and the axis of the soil nail is equal to the radius of the anchor hole of the soil nail.
Above-mentioned structure, centering reinforcing bar and soil nail ligature can not cause the damage to soil nail structure.
As shown in figure 3, the soil nail 1 is inserted into the anchor hole 4, when the soil nail is inserted, the front end of the supporting section 21 of the centering steel bar 2 faces the outside of the anchor hole, and the supporting section slides along the wall of the anchor hole without scratching the wall of the anchor hole. After the soil nail is installed in place, the soil nail 1 is positioned in the center of the anchor hole 4, and the best anchoring effect can be achieved after grouting of the anchor hole.
