Embodiment 1

[0031] Such as Figure 1-4 As shown, a rooted anchor support device is composed of a hollow anchor tube 2 and at least one set of root anchor rod groups 7 matched with the hollow anchor tube 2;

[0032] In the hollow anchor tube 2, one end of the hollow tube body 1 is provided with an anchor head 3, and the inner wall of the hollow tube body 1 is provided with at least one set of slots along the direction of the tube body. Arranged inner wall slots 10, each inner wall slot 10 is provided with a plurality of through holes 8, and the other end of the hollow pipe body 1 is provided with an anchor tube fixing plate 5;

[0033] The root anchor rod group 7 includes two root anchor rods. The root anchor rod includes a vertical main rod 6. The rod 6 is provided with a plurality of horizontal stabbing rods 4 matched with the through holes 8 on the hollow anchor pipe, and the top of the vertical main rod 2 is provided with an anchor rod fixing plate 9 .

[0034] The vertical main rod ...

Embodiment 2

[0038] As shown in 5-8, a method for anchoring and supporting a slope using the above-mentioned anchoring and supporting device, the method includes the following steps:

[0039] Step 1: insert the hollow anchor pipe 2 into the soil body of the predetermined slope surface 15;

[0040] Step 2: Put each root anchor in the root anchor group 7 into the hollow pipe body 1 along the corresponding inner wall slot 10, and align the transverse spurs 4 on each root anchor with the inner wall slot 10 Corresponding through holes 8;

[0041] Step 3: By inserting a force applying device into the hollow anchor pipe 2, the transverse thorns 4 on each root anchor rod pass through the corresponding through hole 8 and enter the soil body of the slope surface 15, Complete the installation of the root anchor group 7;

[0042] Step 4: pull out the force applying rod in the hollow anchor pipe 2 through the pull-out device;

[0043] Step 5: Carry out cement mortar sealing to the hollow anchor pipe...

Abstract

An inner rooting type anchorage supporting device is composed of a hollow anchorage pipe and at least one rooting type anchorage rod set matched with the hollow anchorage pipe; in the hollow anchorage pipe, an anchorage head is arranged at one end of a hollow pipe body, at least one clamping groove set is formed in the inner wall of the hollow pipe body in the pipe body direction, one clamping groove set is composed of two inner wall clamping grooves formed in the diameter direction of the hollow pipe body, each inner wall clamping groove is provided with a plurality of through holes, and an anchorage pipe fixed plate is arranged on the top of the other end of the hollow pipe body. According to the inner rooting type anchorage supporting device and a slope anchorage supporting method thereof, the problem that anchorage rods and soil are prone to loosening can be solved, occlusion and bonding effects between soil and a supporting anchorage tool are improved, and the anchorage supporting effect of a slope is improved.

Description

technical field [0001] The invention relates to the field of slope anchoring, in particular to an internally rooted anchoring and supporting device and a slope anchoring and supporting method thereof. Background technique [0002] Bolt support is a common method in slope support. In ordinary slope anchoring support, the anchor rod is usually driven into the pre-drilled hole in the surface rock mass or the rock mass around the chamber, and the bonding effect between the anchor rod and the soil mass is used to increase the overall strength of the soil mass. sex and stability. However, in ordinary slope anchoring and support, the bond between the anchor rod and the soil due to mutual extrusion is not very strong. With the change of soil conditions such as soil moisture content, the anchor rod and soil It is easy to loose between bodies, which affects the anchoring effect. Contents of the invention [0003] The technical problem to be solved by the present invention is to p...
