Embodiment Construction

[0012] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0013] Such as figure 1 As shown, the anchor rod of the present invention includes a rod body 1. The difference from the prior art is that the anchoring section of the rod body 1 is provided with several elastic attachments 2, and the elastic attachments 2 are arranged on the rod body 1 upwards. The angle at which the elastic branch 2 and the rod body 1 are naturally deployed is 5° to 85°, and the angle at which the elastic branch 2 and the rod body 1 are naturally deployed in this embodiment is 24°. The end of the elastic attached branch 2 is provided with a stressed short branch 3 extending away from the rod body 1 , and there is an included angle between the stressed short branch 3 and the elastic attached branch 2 .

[0014] When used according to engineering needs, such as figure 2 As shown, the anchor rod is gradually and directly impl...

Abstract

The invention discloses an anchor rod, which comprises a rod body (1). An anchoring section of the rod body (1) is provided with a plurality of elastic attached branches (20 which are upwardly arranged on the rod body (1); a natural unfolded angle between each elastic attached branch (2) and the rod body (1) is 5-85 degrees; the end of each elastic attached branch (2) is provided with a stressed short branch (3) which extends along the direction away from the rod body (1); and an included angle is formed between each stressed short branch (3) and each elastic attached branch (2). The anchor rod has the advantages of few construction processes and short construction time.

Description

Technical field: [0001] The invention relates to a soil reinforcing rod, in particular to an anchor rod. Background technique: [0002] At present, the anchor rods used in soil slope support, foundation pit support and base anti-floating generally have three structures, one is the anchoring section with threads, the other is the anchoring section with positioning plates, and the other is It is the anchor section with both thread and positioning plate. When using, generally drill a hole in the soil layer in advance, then put the anchor rod into the hole, and finally grout in the hole. After the slurry solidifies and reaches a certain strength, the anchor rod and the cured slurry start to play a role, preventing The surrounding soil body slides or uplifts. This type of bolt has many construction procedures, and it needs to wait until the grout reaches a certain strength to play a role, so the construction time is also long. Invention content: [0003] The technical proble...
