Embodiment Construction

[0061] see Figure 1-Figure 11 , the composite anchor cable structure of the present invention includes a prefabricated inner anchor head 1, a steel strand 2, a hoop ring 3, a positioning frame 4, a drill hole 5, a primary grouting pipe 7, a secondary grouting pipe 6, and a third grouting pipe 34. Bellows 32, prefabricated grouting body 17 and outer anchoring end E are described as follows:

[0062] 1. Prefabricated inner anchor head 1:

[0063] The prefabricated inner anchor head 1 includes a carrier G, an extrusion sleeve 23, an extrusion spring 24 and a positioning mechanism. The carrier G includes: a steel pressure bearing plate 15 is provided at the bottom of the stainless steel pipe 21 of the anchor head. The center of the anchor head stainless steel pipe 21 passes through the central grouting pipe 18, and a prefabricated grouting body 17 and a threaded stress rib 20 are arranged on the part above the steel bearing plate 15. Around the center of the prefabricated grouti...

Abstract

The invention relates to a compound-type prestressed anchor cable structure. The compound-type prestressed anchor cable structure comprises a prefabricated inner anchor head, a free section, an outer anchoring section and an anchor head part, wherein the prefabricated inner anchor head is provided with steel strands in a penetrating manner; the prefabricated inner anchor head is manufactured in a factory; the prefabricated inner anchor head and the steel strands are adhered to the bottom of a drill hole by using a grouting body; the upper part of the drill hole is the free end, which is at a free state, of each steel strand; the outer anchoring section is arranged at an opening of the drill hole; the anchor head part is arranged outside the opening of the drill hole and is fixed with the top end of each steel strand. The compound-type prestressed anchor cable structure is characterized in that the prefabricated inner anchor head is arranged on the bottom of the drill hole; the outer anchoring section is arranged between the upper end of the free section and the opening of the drill hole; grouting by the grouting body is carried out by three times, wherein the first grouting is stopped in the middle of the free section, fracturing grouting is adopted in the second grouting process to form the anchoring section, and the third grouting is carried out after a grout body of the anchoring section reaches an age and has the capability of stretching the steel strands, namely, the outer anchoring section is subjected to grouting, and except that the steel strand of the free section is at a free state, the steel strands of the inner anchor head and the outer anchoring section are adhered with the grouting body to form the compound-type prestressed anchor cable with the prefabricated inner anchor head and the outer anchoring section.

Description

technical field [0001] The invention relates to a composite prestressed anchor cable structure and a construction method thereof, which are suitable for slope reinforcement projects of roads, railways, mines, municipal administrations and the like. Background technique [0002] As a hidden project, the slope anchoring project is buried in various types of rock and soil as its main materials, steel and concrete. It will be corroded and damaged by various erosive media to varying degrees when it is in contact with groundwater and site soil for a long time, which will cause structural damage. The physical and mechanical properties such as durability and strength are reduced. [0003] In order to improve the durability and effectiveness of anchoring engineering, in addition to improving existing technologies, it is important to study new anchoring structures and develop anchoring technologies with better durability in combination with continuously developing new technologies, ne...
