Abstract
The utility model discloses a tubular bearing head which comprises an outer pipe and a U-shaped ring, with the outer pipe arranged outside the U-shaped ring. A connecting plate is arranged in the outer pipe and is fixedly connected with the outer pipe. The U-shaped ring is arranged at the central part of the outer pipe through the connecting plate, ensuring the tubular bearing head to convey the loadings to an anchor cable body evenly. The loadings are conveyed to the ground through the anchor cable body. In the tubular bearing head, an outer pipe is arranged outside the U-shaped ring to increase the section area of the tubular bearing head, ensuring the U-shaped to be kept at the central part of a bore. The utility model is applicable to a pressure dispersion-type prestressing anchor cable which has to be improved in anti-pull force through enlarging the diameter of the bore at a soft ground. The bore at the tubular bearing head is not enlarged due to the separation of the outer pipe while other bores are enlarged during the drilling construction, ensuring the tubular bearing head to be kept at the relative central position of a circle of the enlarged bore; thereby, the loadings are evenly transferred to the anchor cable body by the tubular bearing head so that the anti-pull force of the anchor cable is improved.
Description
Technical field
The utility model relates to carrier head, particularly a kind ofly is used for that the construction project basement foundation ditch is gone along with sb. to guard him, the tubular carrier head in the pressure dispersing type prestress anchorage cable of geological hazard control slope reinforcement.
Background technology
The pressure dispersing type prestress anchorage cable is applied to basement foundation ditch and goes along with sb. to guard him, the slope reinforcement that forms because of soil excavation in building, road and the hydraulic engineering, and the slope reinforcement in the geological hazard control is the some in the slope reinforcement tectonic system.Carrier head is the important component of pressure dispersing type prestress anchorage cable, and the load that puts in the prestress anchorage cable is delivered in the anchoring stratum through carrier head and anchor cable body by steel hinge line.
Prestress anchorage cable generally is 10 °～35 ° settings of horizontal sextant angle in the anchoring stratum, the prestress anchorage cable of existing structure, because the action of gravity of steel hinge line and carrier head, carrier head always sinks to the borehole wall downside, even if employing counter-boring techniques, no matter boring expands great degree to, and carrier head always is in below, cross section, boring garden.Because carrier head is in the below of borehole wall, carrier head and anchor cable body and directly contact with the soil body of hole wall not in same axis, and its load can not be delivered in the anchor cable body effectively, and the intensity of the soil body is far below the cement paste intensity of anchor cable body, thereby causes the resistance to plucking of prestress anchorage cable lower.
Summary of the invention
The purpose of this utility model be provide for the deficiency that solves above-mentioned technology a kind of can make carrier head place drill center, effectively transmit load, improve the tubular carrier head of the uplift resistance of anchor cable.
In order to achieve the above object, the tubular carrier head that the utility model is designed, it is made up of outer tube and U-loop, and outer tube is arranged on the outside of U-loop.Be fixedly connected with junction plate in the outer tube, U-loop is arranged on the centre of outer tube by junction plate, and tubular carrier head can be delivered to load in the anchor cable body uniformly, is delivered in the soil body through the anchor cable body again.
The resulting tubular carrier head of the utility model by increased the sectional area of carrier head at U-loop outer setting outer tube, makes U-loop remain on the drill center position.Tubular carrier head is suitable for soft stratum especially, needs through enlarging the pressure dispersing type prestress anchorage cable that bore diameter improves uplift resistance.In the reaming construction, owing to be subjected to the obstruct of outer tube, carrier head boring partly can be not extended, and the boring beyond the carrier head is enlarged through the reaming construction, make carrier head can remain on the relative home position of extended boring, thereby guaranteed that carrier head can transfer loads in the anchor cable body uniformly, is improved the uplift resistance of anchor cable.
Description of drawings
Fig. 1 is the front view of the utility model embodiment 1 tubular carrier head;
Fig. 2 is that the utility model embodiment 1 tubular carrier head is used in combination structural representation;
Fig. 3 is the right view of the utility model embodiment 2 tubular carrier heads.
The utility model will be further described in conjunction with the accompanying drawings below by embodiment.
As shown in Figure 1, the tubular carrier head that present embodiment is described, it is made up of outer tube 3 and U-loop 2, and outer tube 3 is arranged on the outside of U-loop 2, and to increase the sectional area of tubular carrier head, steel hinge line 1 is walked around U-loop 2 in outer tube 3 inside, and draw outside the boring at two ends.
As shown in Figure 2, the application of tubular carrier head in the pressure dispersing type prestress anchorage cable, the muscle of forming by steel hinge line 1 and tubular carrier head of being advocated, place boring 5, construct through reaming again, make that the bore diameter except that tubular carrier head position is enlarged, make tubular carrier head can remain on the position that enlarges the relative center of boring, thereby improved the uplift resistance of anchor cable greatly.According to the uplift resistance requirement of geological conditions and anchor cable, tubular carrier head can singlely use, and also can several be used in combination.
The tubular carrier head that present embodiment is described, be welded with junction plate 1 in its described outer tube 4, U-loop 3 is arranged on the centre of outer tube 4 by junction plate 1, and tubular carrier head can be delivered to load in the anchor cable body uniformly, is delivered in the soil body through the anchor cable body again.
Claims (2)
1. tubular carrier head, it is made up of outer tube (3) and U-loop (2), it is characterized in that outer tube (3) is arranged on the outside of U-loop (2).
2. tubular carrier head according to claim 1 is characterized in that being fixedly connected with in the described outer tube (3) junction plate (4), and U-loop (2) is arranged on the centre of outer tube (3) by junction plate (4).
