Embodiment
Below in conjunction with drawings and Examples, the utility model is further described.
Embodiment one
A kind of foundation earth anchor as shown in Figure 1, 2, comprises anchor log and connector.Described anchor log is made up of the anchor head 1 in one, anchor body 2 and anchor tail 3, is steel pile structure.Anchor head 1 is in conical structure; Anchor body 2 and anchor tail 3 in cylindrical structure, and are hollow structure.Described connector comprises screw rod 4, the 1st nut 5, the 2nd nut 6, the 3rd nut 7, the 4th nut 8, movable part 9, handle 10, hand point.Described hand point comprises steel plate strip 11, the 1st steel nail 12, the 2nd steel nail 13, the 3rd steel nail 14.
Movable part 9 is in the shape of a hoof, and it is outside that part is enclosed in anchor tail 3.Screw rod 4 is successively through the other end of one end of movable part 9, anchor tail 3, movable part 9.The two ends of screw rod 4 are fixed with the 1st nut 5 and the 2nd nut 6 respectively.Handle 10 through the hole on movable part 9 stage casing, the both sides in described hole respectively with the 3rd nut 7 and the 4th nut 8 fixed handle 10 in order to avoid handle 10 slidably reciprocates in the hole; Handle 10 can with its cross section center of circle for axle rotates in described hole, to adapt to the diverse location angle at trees ' root place.Movable part 9 can rotate relative to anchor tail 3 for axle with screw rod 4, thus band fixed handle 10 and described hand point move up and down, to adapt to the diverse location height at trees ' root place.Steel plate strip 11 is arranged on the front end of handle 10, and the 1st steel nail 12 and the 2nd steel nail 13 points are located at the two ends of steel plate strip 11, and the 3rd steel nail 14 is arranged on the end of the front end of handle 10.
Anchor body 2 in Fig. 1 adopts omissive representation.
During installation, the general not requirement of angle in soil squeezed into by the anchor log of described foundation earth anchor, and can vertically squeeze into, the certain angle that also can tilt is squeezed into.One strain trees can use 1 ~ 3 described foundation earth anchor to be fixed near its main root.
Drag is tested: described anchor log is that ordinary steel material is made, plating zinc on surface.Anchor head 1 is solid construction; Anchor body 2 and anchor tail 3 are hollow-core constructions, and its external diameter is 80mm, and internal diameter is 70mm.Described connector is that stainless steel material is made.
One, single foundation earth anchor drag test
Table 1 is the trees for 4 meters, same tree crown centre distance ground, after the described foundation earth anchorage trees ' root of single different length, in the drag size that overhead 2 meters of height chest expanders record, and the drag size recorded at distance 2 meters, ground chest expander with these trees of unrooted base anchor process.
Table 1 single foundation earth anchor drag results contrast
| Single foundation earth anchor length or unrooted base anchor | The drag (kg) at 2 meters of | The drag (kg) at 4 meters of |
| 0.6m | 1490 | 745 |
| 0.8m | 2232 | 1116 |
| 1.0m | 2406 | 1203 |
| Unrooted base anchor | 796 | 398 |
The drag at 2 meters of is the drags recorded by chest expander; The drag at 4 meters of is drags that tree crown center and main wind-engaging blast place can bear, and is calculated by formula F 1 × L1=F2 × L2.F1 represents the drag at 2 meters of; L1 represents the distance of F1 distance tree root, is 2 meters herein; F2 represents the drag at 4 meters of; L1 represents the distance of F2 distance tree root, is 4 meters herein.
Single foundation earth anchor considerably increases the drag of trees as shown in Table 1.
Two, three foundation earth anchor drag tests
Table 2 is the trees for 4 meters, same tree crown centre distance ground, after the described foundation earth anchorage trees ' root of three equal length of three groups of different lengths, in the drag size that overhead 2 meters of height chest expanders record, and the drag size recorded at distance 2 meters, ground chest expander with these trees of unrooted base anchor process.
Table 2 three foundation earth anchor drag results contrast
| Three foundation earth anchor length or unrooted base anchor | The drag (kg) at 2 meters of | The drag (kg) at 4 meters of |
| 0.6m | 2252 | 1126 |
| 0.8m | 2354 | 1177 |
| 1.0m | 2716 | 1368 |
| Unrooted base anchor | 726 | 363 |
Three foundation earth anchors considerably increase the drag of trees as shown in Table 2.
For the trees on 4 meters, the tree crown centre distance ground of one tree, suppose that its area perpendicular to wind direction plane is 6 square metres.So when wind-force reach very large intensity time, when such as to produce perpendicular to the blast of every square metre in wind direction plane be 130kg, strong wind is 780kg to its blast produced.From table 1 and table 2, except the described single earth anchor of single 0.6m can not resist strong wind now, foundation earth anchor cited in table all effectively can resist the strong wind of this blast size.And during the anchor of unrooted base, these trees then cannot resist the strong wind of this blast size.
