Abstract
The utility model discloses a composite anchor rod device for foundation treatment, which is formed by welding three deformed steel bars and a positioning ring, wherein the three deformed steel bars are welded outside the positioning ring, and the three deformed steel bars are parallel and fixed in interval above the ring; the three deformed steel bars are bound at the part below the circular ring to form a cone, and the lower ends of the three deformed steel bars are welded together; the utility model has simple structure and easy processing and manufacturing; the structure is stable and safe, and the drill hole is easy to insert and convenient to construct; the anchor rod is big with the slurry area of contact, can strengthen the bonding effect of reinforcing bar and slurry, and then promotes the anchoring ability of single anchor rod, reduces the anchor rod use amount, practices thrift construction cost.
Description
Technical Field
The utility model relates to a tunnel construction equipment especially relates to a compound stock device for ground is handled.
Background
In recent years, environmental problems caused by development of underground spaces such as urban rail transit and the like are attracted by wide attention, and particularly, problems that a shield penetrates through a pile foundation of a ground surface structure in a short distance and the like are prominent. In order to reduce the adverse effect of shield construction on surrounding pile foundations, an isolation pile needs to be arranged between the existing pile foundations and the shield tunnel. At present, the form of keeping apart the stake adopts bored concrete pile and spouts stock pile etc. soon more, the utility model discloses mainly be to spouting stock pile design soon, in the actual work progress of spouting stock pile soon, the phenomenon of "hole of collapsing" often appears for the stock is difficult for inserting, delays the construction progress greatly. In order to solve the above-mentioned construction problems, it becomes important to develop a new anchor rod.
SUMMERY OF THE UTILITY MODEL
To above-mentioned condition, in the work progress of jet grouting anchor pile, in order to deal with the hole phenomenon of collapsing that probably appears, the utility model provides a compound stock device for ground is handled.
A composite anchor rod device for foundation treatment is formed by welding three deformed steel bars and a positioning ring, wherein the three deformed steel bars are welded on the outer side of the positioning ring, and meanwhile, the parts of the three deformed steel bars above the ring are kept parallel and fixed in interval; the three threaded steel bars are bound below the circular ring to form a cone, and the lower ends of the three threaded steel bars are welded together.
The three threaded steel bars and the positioning ring are continuously welded together to form a welding seam.
After the lower ends of the three threaded steel bars are welded together, the three threaded steel bars continue to extend downwards for continuous welding to form a welding joint, so that the connection strength of the three steel bars is increased.
The positioning ring is a connecting part for positioning the reinforcing steel bars, so that the material of the positioning ring is required to have better weldability, and the preferred material is low-carbon steel.
Under the condition that the drilling is deeper, the number of the positioning rings can be increased to keep the stability of the upper half section of the twisted steel, the number of the positioning rings is N, and N is larger than or equal to 1.
The beneficial effects of the utility model
1. Simple structure and easy processing and manufacturing.
2. The anchor rod is big with the slurry area of contact, can strengthen the bonding effect of reinforcing bar and slurry, and then promotes the anchoring ability of single anchor rod, reduces the anchor rod use amount, practices thrift construction cost.
3. Stable in structure safety easily inserts the drilling, the construction of being convenient for.
Drawings
FIG. 1 is a schematic structural view of the present invention;
FIG. 2 is a schematic view of a cone structure;
fig. 3 is a schematic view of the positioning ring.
Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
A composite anchor rod device for foundation treatment is shown in figure 1 and is formed by welding threaded steel bars 1 and a positioning circular ring 2, wherein the three threaded steel bars 1 are welded on the outer side of the positioning circular ring 2, the parts of the three threaded steel bars 1 above the circular ring 2 are kept in parallel and fixed at intervals, so that the bonding effect of the steel bars and slurry is enhanced, the reinforcing capability of a single anchor rod is further improved, the using amount of the anchor rod is reduced, and the construction cost is saved; the three deformed steel bars 1 are bound below the circular ring 2 to form a cone, and the lower ends of the three deformed steel bars 1 are welded together. The concrete structural form of the conical body refers to fig. 2, so that the drilling hole 5 is convenient to insert, the construction is convenient, the phenomenon of hole collapse which possibly occurs is effectively solved, and the construction speed is improved.
The three deformed steel bars 1 and the positioning circular ring 2 are continuously welded together to form a welding joint 3.
The cone body is shown in fig. 2, after the lower ends of the three threaded steel bars 1 are welded together, the three threaded steel bars continue to extend downwards for continuous welding to form a welding joint 4, and therefore the connection strength of the three steel bars is improved.
As shown in fig. 3, the positioning ring 2 is a connecting component for positioning reinforcing steel bars, and three reinforcing steel bars are welded in parallel on the positioning ring 2 and keep the same distance, which requires that the material of the positioning ring has better weldability. Low carbon steel with stronger weldability is generally selected.
In the field construction process, if under the condition that drilling 5 is than deep, can increase the stability that the number of location ring 2 kept the first half of twisted steel 1, the number of location ring 2 is decided by the bore depth, but is no less than 1.
Modifications and variations are possible in light of the above teachings, and all such modifications and variations are intended to be included within the scope of the following claims.
