Description
Technical field
The invention belongs to Rock And Soil reinforcement technique fields, and in particular to a kind of anchoring section radial direction lengthening expansion increasing resistance anchor
Bar.
Background technique
Anchor pole is widely used in a kind of engineering measure of Rock And Soil reinforcing.Anchor pole belongs to pulling force rod piece architecture, passes through
The effect of body of rod pulling force transmitting, the Rock And Soil for being readily able to sliding are tightly pressed against on the Rock And Soil of deep stability, increase Rock And Soil
Frictional force, so as to improve the stable state of shallow rock soil body.
Most of anchor pole is that withdrawal resistance is provided using anchoring section-triangular frictional resistance of mortar-Rock And Soil, however sand
The limited modulus of pulp material and intensity are difficult to provide enough withdrawal resistances;In addition, anchor pole during one's term of military service, mortar is vulnerable de-
It falls, anchor pole is caused to can not work normally.For these problems, engineers and technicians have invented another kind of anchor pole at present, i.e., by anchor
Gu enhancing resistance to plucking resistance using the high intensity and high-modulus characteristic of reinforcing bar, while guaranteeing anchor pole not in section expansion insertion Rock And Soil
Transmitting load can be failed to because of mortar to Rock And Soil, it is ensured that anchor pole is on active service steadily in the long term.
A kind of herring-bone form anchor pole is disclosed in the Chinese patent of Patent No. 201610999648.3.But it is deposited when anchor pole is too long
In the problem of rotation process difficulty, and blade is meticulous excessively thin causes intensity deficiency that can not provide enough withdrawal resistances.Number of patent application
To disclose the attached branch recoverable anchor rod of segment type elasticity in 201711395993.7 Chinese patent.But such anchor pole because it is meticulous not
Suitable for big depth engineering reinforcement Rock And Soil, and deployment mechanism disclosed in patent not can guarantee the attached branch of elasticity can smoothly be inserted into rock
In the soil body, in addition elastic attached branch and anchor pole junction are weak, and there is also the problems of intensity deficiency.In short, existing anchor pole is inserted into rock
The blade of the soil body or attached Zhi Qiangdu are generally insufficient, and interposer and the unbearable larger load of anchor bar body connecting portion are easy
Existing breakage phenomenon, the effect for enhancing resistance to plucking resistance is not satisfactory, is unfavorable for achievements conversion application of such anchor pole in engineering.

In on 5 inner wall of expanding reach, second knife plate 9 is under the connecting rod 10 drive in the guide-track groove 507 along the expansion
5 axis upward slidings of section, when second knife plate 9 is flushed with 8 plate of the first knife, it is recessed that the dovetail protruding portion is caught in the dovetail
In concave portion, while one end of the flexible connector 11 is inserted into the spliced eye 804, connects first knife 8 and described the
Two knife plates 9;When first knife 8 and the second knife plate 9 are fully deployed, the fixed block 710 is inserted into the limit hole 902,
For locking second knife plate 9.
The working principle that a kind of anchoring section of the present invention radially lengthens expansion increasing resistance anchor pole is specific as follows:
When being not used, first knife plate 8 is leaned against on small cushion cap 703, and is located in expanding reach 5;Second knife plate, which is located at, to be expanded
In big section 5.
As shown in figure 12, in use, first drilling through a deep hole on Rock And Soil, the anchor pole is inserted into deep hole, interior anchor pole 2
It is connect by lock nut 3 with stretching device.After being completely fixed in the anchor pole insertion deep hole, then interior anchor pole 2 is given to apply outward
The power of lifting, interior anchor pole 2 drive longitudinal rod 701 to move outward, so that the first knife plate 8 in expanding reach 5 progressively disengages and small holds 703
Platform is along arc guide rail 705, while the first knife plate 8 is moved radially along anchor pole, while releasing the first limit bolt 505 and the second limit
Limitation of the bolt 702 to the first knife plate 8, along anchor pole, radially across the second square hole 502, ground is inserted into expansion to the first knife plate 8 outward
In body;Second knife plate 9 moves up under the pulling force effect of connecting rod 10 along guide-track groove pulley group 508, continues the longitudinal direction that pulls outward
Bar 701, the first knife plate 8 continues on arc guide rail 705 from 502 radial development of second hole, when the opposite shifting of the first knife plate 8 at this time
It moves to big cushion cap 704, arc guide rail 705 no longer provides radial propulsive force to the first knife plate, and the first knife plate 8 is due to Rock And Soil
Squeezing action and fixation can not move, at this point, the dovetail protruding portion 803 and spliced eye 804 of the first knife plate 8 just with the expansion
5 inner walls of section are overlapped.
As shown in Figs. 13 and 14, the continuation of longitudinal rod 701 lifts outward, the dovetail recessed portion 904 and first on the second knife plate 9
The dovetail protruding portion 803 of knife plate 8 is connected, and the flexible connector 11 in the second knife plate 9 in compressive state springs into inserting for the first knife plate 8
It connects in hole 804, two knife plates form a whole knife plate, are cantilever beam structure on mechanical structure, can bear the power of any direction
With torque without mobile and rotation;The continuation of longitudinal rod 701 lifts outward, and connecting rod 10 does circumference with respect to the first articulated shaft 708
Movement pushes the continuation of the second knife plate 9 radially to further spread out in the insertion soil body, until connecting rod 10 is parallel with force bearing plate 709, holds
Fixed block 710 on power plate 709 is inserted into the limit hole 902 of the second knife plate 9, at this point, fully unfolded position is presented in two knife plates;
Interior anchor pole 2 is locked in fixed disk 1 by lock nut 3, is fallen to prevent interior anchor pole 2;Finally in hole perfusion mortar, mud or
The slurry of cement slurry, slurry flows into the expanding reach 5 from the first square hole 501, third square hole 503, and passes through arcuate socket
711 fill full expanding reach 5, and anchor bar body is freezed solidly in Rock And Soil.
