Abstract

The present invention is designed for the anchor device structure in the underground anchoring method, which is constructed when it is impossible to guarantee the reliability of the stable state of the ground or when it is judged that it is necessary to firmly maintain the current state. Examples of crafts include maintaining and reinforcing the ground to stabilize the collapse of slope collapse, land sliding prevention work, retaining wall reinforcement work, building foundation buoyancy prevention work, Dolphin buoyancy wind power construction, and earthquake-resistant construction work. Anchor construction is carried out in order to do this, but the conventional anchor construction as described above first drills the target ground to a certain length to form a perforated part, inserts a tension member made of a metal rod into it, and injects cement milk between the tension member and the perforated part. It was a method of curing and solidifying If there is an underground vein, the adhesion between the inner wall of the space portion and the cement milk fixing the tension member is weak, there was a problem of lowering the fixing effect.

The present invention is equipped with the anchor device of the present invention to the end of the tension member to maintain the stable state of the ground to solve the above problems, by this anchor device to firmly support the dangerous ground with short air and low construction cost It is about devising to make it possible.

The present invention is a design for the anchor device structure in the underground anchor construction method, which can be constructed when it is impossible to guarantee the reliability of the stable state of the ground or when it is determined that it needs to be firmly fixed. Examples of the construction include maintaining the stable state of the ground in the collapse prevention work in case of slope collapse, Land Sliding prevention work, molten wall reinforcement work, building foundation buoyancy prevention work, Dolphin buoyancy wind power work, and earthquake proofing work. And the anchor construction to reinforcement, but the conventional anchor construction as described above, first drills the ground to a certain length to form a perforated part, inserting a tension member made of a metal rod therein and cement milk between the tension member and the perforated part It was the method of curing and solidifying by injecting the bar. If there is an underground water vein, because the adhesion of the cement milk and fixing the tension member and the inner wall of the space portion weak there is a problem of lowering the fusing effect.

The present invention is equipped with the anchor device of the present invention to the end of the tension member to maintain the stable state of the ground to solve the above problems, by this anchor device to firmly support the dangerous ground with short air and low construction cost When devised to devise so as to be described in detail based on the accompanying drawings as follows.

1 is a view illustrating the state of the anchoring construction for the construction of the slope collapse prevention, etc. as the anchor device of the present invention, Figure 2 is the depth of the depth required for the anchor device of the present invention Referring to the anchor device 1 according to the present invention for carrying out the anchor construction in the first and second diagram as a work flow chart showing a state of insertion and mounting sequentially, the lower portion of the tension member (2) having a certain strength and length The inner cylinders 3 and the lower cylinder 1b of which the inside is hollow, respectively, are inserted into the inner cylinder 3 and the outer cylinder 4 sealed up and down, and the inner cylinder 3 has a constant height at the outer periphery of the lower end of the inner cylinder 3; And through the through hole 6 penetrating the dolwon (5) to connect the lower part of the through hole (6) and the pipe (7) for injection of the chemical (cement milk or mortar), but the pipe for the injection of the chemical A ( 7) is withdrawn to the inner cylinder (3) upper surface (1a) for A chemical solution injection A plurality of ANCHORBAR (10) to be connected to the frame (not shown in the drawing) and the hinge (9) coupled to the inner circumferential wall (3) and the upper outer wall of the support bracket (8) is hinged freely The front end of the anchor bar 10 forms an edge portion 15a with an arc in a direction opposite to the upper end edge portion 15 of the outer cylinder 4.

The through-hole 12 is located outside the inner cylinder 3 of the structure described above so that the front end portion 11 of the tension member 3 is mounted in the center of the lower surface 1b of the outer cylinder 4 connected to the inner cylinder 3 up and down. 2 is formed in the lower surface (1b) is laid out a plurality of discharge holes 13 for discharging the liquid B and the outer circumferential surface of the upper end of the outer cylinder (4) the same height as the height of the dolwon (5) protruding in the lower end of the inner cylinder (3) Protruding the inner dolwon 14 with the dolwon (5) of the inner cylinder (3) to ensure a constant space (S) between the dolwon (5) and the inner dolwon 14 and the dolwon (5) and the outer cylinder inner peripheral surface The abutment surface of the dolwon 14 and the abutment surface of the outer circumferential surface of the inner cylinder 3 are each interposed with a sealing material (P) (Pa) in order to maintain closeness.

Then, the B chemical liquid injection pipe 7a penetrates the inner cylinder surface 1a to the predetermined position of the outer cylinder 4 inside the outer cylinder 4, and the outer edge 4 of the outer cylinder 4 has a circular arc. By forming, the anchoring device 1 of this invention is comprised. The part A (clamping part) shown in FIG. 1 is a well-known method, and thus description thereof is omitted. Unexplained reference numeral 16 in the drawing indicates the underground drilling portion for the anchor construction.

When explaining the operation state of the present invention configured as described above

To do anchor construction like the first degree

A chemical solution is fixed through the A chemical liquid injection pipe 7 while the anchor device 1 of the present invention is inserted into the lower portion of the underground drilling unit 16 by working in the same order as in Figs. When injected at the pumping pressure, the chemical A is injected into and filled with the space S provided between the inner cylinder 3 and the outer cylinder 4 of the anchor device 1 through the pipe 7 while being filled with the outer cylinder 4. The inner circumferential source 14 of the inner cylinder 3 and the inner circumferential wall of the outer cylinder 4, and the inner circumferential wall 14 of the inner cylinder 3 Since the sealing material (P) (Pa) is interposed and sealed between the outer circumferential wall, respectively, the A chemical liquid filled into the space (S) does not leak and pushes the outer cylinder (4) upward.

When the outer cylinder 4 rises in this way, the lower end of the anchor cover 10 and the upper end edge of the outer cylinder 4 are fixed to the outer circumferential surface of the inner cylinder 3 with the hinge 9 as the outer cylinder 4 rises. The lower end of the anchor bar 10 coupled to the hinge 8 to the inner cylinder 3 has a circular arc at the corner 15a, and the upper end of the outer cylinder 4 also has a corner 15 at both ends. Since it is formed in an arc in a direction opposite to the arc of the corner (15a) of the anchor cylinder (10) by the continuous rise of the outer cylinder (4) slides in response to the upper edge of the outer cylinder (4), a plurality of anchors The bars 10 are spread out at regular inclinations to the outside, respectively. Meanwhile, the B drug solution injected through the B drug injection pipe 7a fills the interior space of the anchor device 1 according to the present invention, and also through the underground hole through the discharge hole 13 installed in the bottom of the outer cylinder 4. The empty space of (16) is filled, and in this state, the A and B chemicals filled in the underground perforation part 16 and the inner space of the anchor device 1 are quickly settled, and the anchor bar 10 which is opened outward at a predetermined angle is As the anchor device 1 itself is firmly fixed in the ground in the state of being opened, it is possible to perform anchor construction such as retaining wall reinforcement work, slope collapse prevention work, etc. as a simple structure and construction cost.
