Description

The anchorage element that is used for emergent flood spillway erosion control material
Technical field
The utility model relates to a kind of for the fixing member of flood spillway erosion control material, belongs to the hydraulic engineering technical field.
Background technology
Existing anchorage element in use, need long rod member more and imbed darker, come the anchoring soil body with this, reach the purpose of member resistance to plucking, because the phase mutual friction between that part of rod member and surrounding soil in the soil body is imbedded in its main uplift resistance source, when member began loosening in the soil body and extracts, its resistance to plucking effect reduced along with extracting of member.
Understand according to the applicant, when emergent flood spillway erosion control material anchoring, set-up time to anchorage element has relatively high expectations, when emergent flood spillway overflows flood, current produce a uplift force to anchorage element, therefore for emergent flood spillway is set fast, must adopt the short anchorage element of the general member of length, must guarantee the anchorage element of weak point guarantee the to meet an urgent need anchoring effect of flood spillway erosion control material of length simultaneously.
The utility model content
First technical problem to be solved in the utility model is at the prior art deficiency, to propose the anchorage element that is used for emergent flood spillway erosion control material that a kind of set-up time is fast and resistance to plucking is effective.

The specific embodiment
Embodiment one
The anchorage element that is used for emergent flood spillway erosion control material of present embodiment as depicted in figs. 1 and 2, comprises nail bar 1, is located at the nail point 2 of following closely bar one end and the ailhead 3 of being located at the nail bar other end.Nail bar 1 middle part is shaped at least one through hole 1-1.Coaxial 5 are hinged with a pair of thorn of expansion certainly 4 that is in the shape of the letter V in the through hole 1-1, and the dead end 4-1 that expands thorn certainly stretches out in through hole 1-1.
When anchorage element hammered into the soil body, the dead end 4-1 that a pair of expansion thorn certainly 4 rotates close to each other and expansion thorn certainly in opposite directions were resisted against obliquely and follow closely on the bar 1; When anchorage element upwards is pulled up from the soil body, a pair ofly leaves nail bar 1 from the dead end 4-1 that expands thorn 4 reverse rotations away from each other and expand thorn certainly and insert in the soil body.
For when nail bar 1 is hammering into the soil body and pulling up, have interactional uplift resistance all the time between nail bar 1 and the soil body, the nail bar 1 of present embodiment is to wait straight-bar.Hammer into the soil body for anchorage element is easier, the nail point 2 of present embodiment is made as taper shape.The length of the expansion thorn certainly 4 of present embodiment is greater than the length of through hole 1-1.
Be provided with two locator protrusions 1-2 in the through hole 1-1 of present embodiment relatively, two locator protrusions 1-2 are along the direction setting of through hole 1-1.When anchorage element upwards is pulled up from the soil body, a pair of from expanding thorn 4 reverse rotations away from each other and being resisted against on the locator protrusions 1-2.
Experiment showed, that when anchorage element upwards is pulled up a pair of when expanding angle between the thorn 4 smaller or equal to 120o, it is bigger to expand between thorn 4 and the soil body interactional uplift resistance certainly, the resistance to plucking better effects if from the soil body.
The center line of the axis of the axle 5 of present embodiment, nail bar 1 length direction and the center line of through hole 1-1 are vertical each other.Certainly, the center line of the center line of the axis of axle 5, nail bar 1 length direction and through hole 1-1 each other can be not vertical mutually yet.
The ailhead 3 of present embodiment is made as nut, the nail bar 1 be shaped on the screw thread that is spirally connected with nut, nut be screwed onto the nail bar 1 on and can along the nail bar about in the of 1 spiral move.
Also be provided with dismountable handle 6 on the nail bar 1 of present embodiment, nail bar 1 is shaped on the handle installing hole that is positioned at the nut top.
As shown in Figure 3, the expansion certainly of present embodiment thorn 4 is made as taper.
As shown in Figure 4 and Figure 5, during actual the use, anchorage element length is 50.5cm, stinging 4 length from expansion is 5cm, the nail bar 1 of anchorage element is 60 ° with the angle that stings 4 from expansion, the uplift resistance maximum value of anchorage element is 430N, according to field trial, pulls out the maximum value that 4cm then reaches uplift resistance on the anchorage element.
Embodiment two
The anchorage element and the embodiment one that are used for emergent flood spillway erosion control material of present embodiment are basic identical, as shown in Figure 6 and Figure 7, difference is except identical with embodiment one: a pair ofly be connected with spring 7 from expanding between the thorn 4, a pair ofly go up binding rope 8 is arranged from expanding thorn.When rope 8 tightens, a pair of expansion thorn certainly 4 overcomes spring force to be drawn close each other; When rope 8 was lightened restrictions on, a pair of thorn 4 that expands certainly was separated from each other under the spring force effect.
During actual the use, earlier anchorage element is knocked in the soil body, when the dead end 4-1 that expands thorn certainly of anchorage element is about to imbed the soil body, untie rope 8, continue again anchorage element is rammed the soil body, destruction from the surrounding soil of the anchorage element of dead end 4-1 that expands thorn is littler, and contacting between nail bar 1 and the soil body is tight.When pulling out on the anchorage element, under the effect of spring 7, easier making from the soil layer that expands thorn 4 tops promotes a pair ofly to leave nail bar 1 from the dead end 4-1 that expands the thorn reverse rotation away from each other and expand thorn certainly and insert in the soil body, when pulling out 5cm on the anchorage element, launch fully from expanding thorn 4, at this moment anchorage element uplift resistance maximum.Find that through actual the use anchorage element uplift resistance of the present utility model significantly improves the stability of member anchoring than having improved 60% under the general case.
The utility model is not limited to above-described embodiment.All employings are equal to replaces the technical scheme that forms, and all drops on the protection domain of the utility model requirement.
