Description

Technical Field

[0001] This invention belongs to the field of geotechnical engineering and relates to a slope anchoring structure, specifically a link anchoring structure for a suspended flexible slope support system. Background Technology

[0002] Flexible slope protection nets, prestressed anchor cable frames, and anti-slide piles are widely used. Among them, flexible slope protection nets are used for the reinforcement and protection of soil or rock slopes with potential geological hazards such as collapse, landslide, shallow sliding, and rockfall. They are mainly used in engineering fields such as deep slope sliding, large landslides, and slope protection.

[0003] Suspended flexible protection technology has the advantages of short construction and installation cycle, fast construction speed, no need for shoveling, applicability to various complex terrains, and integration of the entire slope into a whole.

[0004] 1. The suspended flexible slope support system has a small frame volume, especially when the landslide thrust is large. The reinforced concrete volume of the frame structure is very small, and the concrete area of ​​the slope surface is small, making it easy to achieve slope greening.

[0005] 2. Sloping frame construction is easy and fast, making it particularly suitable for emergency rescue or temporary projects.

[0006] 3. It is suitable for rapid and large-scale construction, making it very convenient to carry out mechanized or semi-mechanized construction.

[0007] 4. The entire frame system is a whole, and there is no need for expansion joints to separate the frames. As a result, if a local collapse occurs, the nearby frames will play a joint anti-slip role.

[0008] 5. The connection between the anchor beam, anchor cable, and anchor rod still cannot effectively convert the tension of the prestressed anchor cable and anchor beam into anti-slip force.

[0009] However, there are no efficient and reliable connecting components for suspension anchor beams, vertical anchor beams, super anchor cables, and transverse anchor beams.

[0010] Therefore, a new solution is needed to address the above problems. Summary of the Invention

[0011] To achieve the above objectives, the present invention relates to a linking and anchoring structure for a suspended flexible slope protection system, the details of which are as follows:

[0012] A linking and anchoring structure for a suspended flexible slope support system includes a main beam hoop 1, a ground anchor pipe 2, an open anchor plate 3, a transverse anchor beam hook 4, an anchor hole 5, an anchor hole opening 6, a transverse anchor beam 7, a main anchor beam 8, a ground anchor cable 9, an anchor plate opening 10, a beam hoop opening 11, a locking main anchor cable 12, a perforated main anchor cable 13, a suspension type anchor beam 14, a vertical anchor beam 15, an end anchor plate 16, and an end locking main anchor cable 17.

[0013] Its features are: the anchor pipe 2 passes through the upper side of the main beam hoop 1 from the lower side and is welded to the outer side of the main beam hoop 1; the transverse anchor hook 4 is mechanically connected to the lower side of the main beam hoop 1; and the open anchor plate 3 is connected to the main beam hoop 1 by a ring welding method.

[0014] The main beam hoop 1 has a hoop opening 11 on each side, and an anchor plate opening 10 is provided at the position where the opening 11 of the hoop 1 connects with the opening anchor plate 3.

[0015] The open anchor plate 3 is provided with anchor holes 5, and a locking main anchor cable 12 is fixed to the anchor holes 5 by steel strand clamps;

[0016] The main beam hoop 1 has perforated main anchor cables 13 installed on both sides of the anchor pipe 2 in the internal space of the space.

[0017] After the perforated main anchor cable 13 is installed inside the main beam hoop 1, the opening 11 of the beam hoop and the opening 10 of the anchor plate are sealed by welding or mechanical connection.

[0018] The open anchor plate 3 is provided with anchor holes 5, and each anchor hole 5 is provided with an anchor hole opening 6. A locking main anchor cable 12 is fixed to the anchor hole 5 by steel strand clamps. After the locking main anchor cable 12 is installed in place, the anchor hole opening 6 is closed by welding. The end anchor plate 16 is placed at the end of the main beam hoop 1. The end anchor plate 16 is provided with anchor holes 5, and each anchor hole 5 is provided with an anchor hole opening 6. An end locking main anchor cable 17 is fixed to the anchor hole 5 by steel strand clamps. After the end locking main anchor cable 17 is installed in place, the anchor hole opening 6 is closed by welding.

[0019] The end-locking main anchor cable 17 is part of the perforated main anchor cable 13.

[0020] This invention relates to a connection and anchoring structure for a suspended flexible slope support system, comprising: a main beam hoop 1, a ground anchor pipe 2, an open anchor plate 3, a transverse anchor beam hook 4, an anchor hole 5, an anchor hole opening 6, a transverse anchor beam 7, a main anchor beam 8, a ground anchor cable 9, an anchor plate opening 10, a beam hoop opening 11, a locking main anchor cable 12, a perforated main anchor cable 13, a suspension type anchor beam 14, a vertical anchor beam 15, an end anchor plate 16, and an end locking main anchor cable 17.

[0021] The advantage of this invention is that it links the main anchor beam 8, the transverse anchor beam 7, and the ground anchor cable 9 together by implementing a linking and anchoring structure for a suspended flexible slope support system in stages.

[0022] Its basic principle is as follows: There are beam hoop openings 11 on both sides of the main beam hoop 1. Part of the steel strand of the main anchor beam 8 is perforated by the main anchor cable 13 and enters into both sides of the anchor pipe 2 inside the main beam hoop 1 through the beam hoop opening 11. After the perforated main anchor cable 13 is installed, the beam hoop opening 11 and the anchor plate opening 10 are closed by welding or mechanical connection.

[0023] The open anchor plate 3 is connected to the main beam hoop 1 by a ring welding method;

[0024] An anchor hole 5 is provided on the open anchor plate 3, and each anchor hole 5 is provided with an anchor hole opening 6. The main anchor cable 12 is installed and locked through the anchor hole opening 6. The main anchor cable 12 is fixed and locked by the anchor clamp. After the main anchor cable 12 is installed in place, the anchor hole opening 6 is closed by welding.

[0025] The end anchor plate 16 is placed at the end of the main beam hoop 1. The end anchor plate 16 is provided with anchor holes 5, and each anchor hole 5 is provided with an anchor hole opening 6. The end locking main anchor cable 17 is fixed to the anchor hole 5 by steel strand clamps. After the end locking main anchor cable 17 is installed in place, the anchor hole opening 6 is closed by welding. Since the height of the end anchor plate 16 is greater than the diameter of the main beam hoop 1, the locking of the end locking main anchor cable 17 on the end anchor plate 16 further prevents the relative movement of the main beam hoop 1 on the main anchor beam 8.

[0026] During construction, the main anchor cable 12 is first tensioned and locked, and then the ground anchor cable 9 passes upward through the ground anchor pipe 2 and is tensioned and locked with the anchor.

[0027] When the link anchoring structure is applied to the vertical anchor beam 15, the vertical anchor beam 15 replaces the main anchor beam 8, and the horizontal anchor beam 7 is connected to the vertical anchor beam 15 through the horizontal anchor beam hook 4. When the link anchoring structure is applied to the suspension type anchor beam 14, the suspension type anchor beam 14 replaces the main anchor beam 8, and the vertical anchor beam 15 replaces the ground anchor cable 9.
