Problems solved by technology

If the anchor cables of the existing specifications are used, a hand-held drilling rig is required to drill holes. The construction speed is slow, the labor intensity is high, the noise pollution is large, the operation is difficult, and there are great safety hazards for people working under the unsupported roof.

Embodiment 1

[0020] in figure 1 A structure of the present invention is shown in the figure, that is, the resin anchoring section of the cable body is a large-diameter mine anchor cable with a cable hoop-type enlarged diameter structure. It is composed of a cable body 11, an anchor 2, a supporting plate 12, and a mixing joint 1. The cable body 11 is composed of a cable body wire 13, a head rigid core tube 9, a flexible core tube 4, a tail rigid core tube 3, a choke hoop 5, a cable hoop 6, a head hoop 7, and a guide cable head 8.

[0021] The front part of the anchor cable body 11 is a resin anchoring section where the resin anchoring agent 10 is used for end anchoring. The anchor 2 and the supporting plate 12 are installed on the cable body 11 at the tail of the anchor cable. The stirring joint 1 is fixedly connected to the tail end of the cable body, that is, the rear end of the rigid core tube at the tail, and is fixedly connected to the cable body wire 13. In the figure, the upper part o...

Embodiment 2

[0037] in figure 2 Another structural form of the present invention is shown in the figure, that is, the cable body resin anchoring section is a large-diameter mine anchor cable with a ring-expanded diameter structure. It is composed of a cable body 11, an anchor 2, a supporting plate 12, and a mixing joint 1. The cable body 11 consists of a cable body steel wire 13, a head rigid core tube 9, a flexible core tube 4, a tail rigid core tube 3, a choke hoop 5, a cable hoop 6, a head hoop 7, a guide cable head 8, and an expansion The ring 14 constitutes.

[0038] The expanded diameter structure adopted in the cable body resin anchoring section in this example is an expanding ring type, that is, the cable body high-strength steel wire in the resin anchoring section between the choke hoop 5 and the head hoop 7 on the cable body resin anchoring section An expansion ring 14 is added between 13 and the rigid core tube 9 of the head, so that the part where the expansion ring 14 is added ...

Embodiment 3

[0041] in Figure 5 The third structural form of the present invention is shown in the figure, that is, the resin anchoring section of the cable body is a large-diameter mine anchor cable with a steel wire outer-wound expanded diameter structure. It is composed of a cable body 11, an anchor 2, a supporting plate 12, and a mixing joint 1. The cable body 11 consists of a cable body steel wire 13, a head rigid core tube 9, a flexible core tube 4, a tail rigid core tube 3, a choke hoop 5, a cable hoop 6, a head hoop 7, a guide cable head 8, and outer It is constructed around steel wire 15.

[0042] The steel wire outer-winding type expansion structure, that is, a cable hoop 6 is arranged between the choke hoop 5 and the head hoop 7 on the resin anchor section of the cable body, and the cable hoop 6 is placed between the choke hoop 5 and the cable hoop 6 Between the hoop 6 and the head hoop 7, an outer winding steel wire 15 having a diameter larger than that of the cable body high-st...

Abstract

A large-diameter anchor cable for a mine is composed of a cable body, an anchor, a support plate and a stirring connector.The cable body is composed of a cable body steel wire, a head rigid core tube, a flexible core tube, a tail rigid core tube, a choke cable band, a cable band, a head cable band, a guide cable end and the like.The external diameter of the cable body is phi 30-50 mm; the head rigid core tube, the flexible core tube and the tail rigid core tube are located in the center of the cable body and connected in sequence; the core tubes can be replaced by a head rigid core rod, a flexible core rod and a tail rigid core rod correspondingly.The external circumference of the cable body resin anchorage section adopts a cable band type or expanding ring type or steel wire wrapping type expanding structure to expand the diameter of the cable body resin anchorage section and reduce a diameter difference between the cable body and a drill hole, and the stirring effect and the anchoring force of resin are improved.The resin anchorage problem of the large-diameter anchor cable is solved for applying the anchor cable to a non-coal mine.Large-diameter anchor cables with different diameters can be processed by means of existing high-strength steel wires according to site requirements.

Description

Technical field [0001] The invention relates to an anchor cable for supporting or reinforcing and reinforcing geotechnical engineering such as underground engineering and tunnels, and in particular to a large-diameter mine anchor cable suitable for non-coal mines. Background technique [0002] At present, the anchor cables used in mines and geotechnical engineering are mainly divided into two types, one is resin anchor cables, and the other is grouting anchor cables. Because the resin anchor cable has the advantages of fast construction speed, high prestress, simple processing, low cost, etc., it is widely used in mine shaft support. The resin anchor cable is first anchored with resin on the anchor cable body, and then a pallet and rigging are installed at the tail of the anchor cable for pre-tensioning. To ensure the quality of anchoring, the difference between the diameter of the cable body and the diameter of the drill hole is required to be in the range of 6-10mm. However, ...
