Embodiment Construction

[0030] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0031] Such as figure 1 with figure 2 A kind of expansive soil anchor cable grout stop shown, comprises centering bracket 1, steel strand 2, high-pressure grouting pipe 3 and expansive soil ( figure 1 The dry soil 4 comprising the initial expansive soil and the expansive soil 5 after expansion are shown in , the expansive soil is wound between each of the steel strands 2 after being packaged with a flexible material, and the high-pressure grouting pipe 3 Passing through the expansive soil, the centering bracket 1 is arranged at both ends of the expansive soil anchor c...

Abstract

The invention discloses an expansive soil anchor rope stop-grouting plug, and an anchor rope structure using the same and a construction method thereof. The expansive soil anchor rope stop-grouting plug comprises centering brackets, steel strands, high-pressure grouting pipes and expansive soil, wherein the expansive soil is wound among all the steel strands after being packaged by a flexible material; the high-pressure grouting pipes penetrate through the expansive soil; and the centering brackets are arranged at the two ends of the expansive soil anchor rope stop-grouting plug. When the grouting or even the high-pressure grouting is performed, a free section and an anchorage section of an anchor rod can be thoroughly separated, on one hand, the pulp leakage and pulp return can be prevented during the grouting, and on the other hand, the pulp can be preferably dispersed and compacted under the effect of grouting pressure; the expansive soil anchor rope stop-grouting plug is simple in structure; and the materials of the stop-grouting plug are richer in southwest China, and are low in price.

Description

technical field [0001] The invention relates to the technical field of engineering construction such as bridges, in particular to a construction method for an anchor cable structure using expansive soil anchor cable grout stoppers. Background technique [0002] At present, there are many types of grout stoppers for anchor cables, including a certain elastic conical plug body, two metal positioning plates and an expanded rubber body. However, the above-mentioned two anchor grout stoppers are usually placed near the orifice. If they are applied to anchors with long free sections, the construction will be difficult and the application fields will be limited. Therefore, it is very urgent to invent a new and practical grout stopper for the anchorage section of the anchor cable for the anchor rods with longer free sections in foundation pit engineering and slope protection engineering. Contents of the invention [0003] The purpose of the present invention is to design a kind o...
