Embodiment Construction

[0029] figure 1 and Figure 5 It shows an embodiment of an integral U-shaped anchor cable pre-embedded channel of the present invention, the pre-embedded channel includes a U-shaped pipe 1, a plurality of steel strands 2, a plurality of isolation rings 3 and pre-embedded and fixed in the concrete foundation A plurality of brackets 4, the U-shaped pipe 1 is fixed on a plurality of brackets 4, and a plurality of spacer rings 3 are evenly spaced in the U-shaped pipe 1, and a plurality of steel strands 2 pass through all the spacer rings 3 in turn, and are formed by The spacer ring 3 isolates multiple steel strands 2 from each other, which can prevent the steel strands 2 from forming mutual interference and extrusion in the U-shaped pipe 1, so that the prestress distribution of the steel strands 2 is more uniform, and can effectively improve the overall U-shaped pipe. The construction quality of the type anchor cable pre-buried channel, and the structure is simple and reliable, c...

Abstract

The invention discloses an integral U-shaped anchor rope embedded duct and a mounting method thereof. The embedded duct comprises a U-shaped pipeline, a plurality of steel strands, a plurality of isolating rings and a plurality of supports, the supports are fixedly embedded into a concrete foundation, the U-shaped pipeline is fixed onto the supports, the isolating rings are uniformly arranged in the U-shaped pipeline at intervals, and the steel strands sequentially penetrate all the isolating rings and are mutually isolated by the isolating rings. The embedded duct is simple in structure, prestress is uniformly distributed, and construction quality can be effectively improved. The mounting method includes the steps: 1) mounting a rope penetrating duct; 2) feeding and winding the steel strands; 3) enabling bundled ends of the steel strands to penetrate into a comb hole device and the isolating rings; 4) connecting a guider with a pulling rope; 5) penetrating the rope; 6) performing measuring, adjusting and positioning.

Description

technical field [0001] The invention relates to a U-shaped anchor cable and an installation method thereof, in particular to an integral U-shaped anchor cable pre-buried tunnel and an installation method thereof. Background technique [0002] The type of prestressed anchor cables for gate piers of high arch dams in my country is traditionally designed as linear anchors. Ertan Hydropower Station is the first high arch dam in China to use U-shaped anchor cables. The use of U-shaped anchor cables does not require the installation of corridors, shafts, etc., and achieves the purpose of not weakening the dam structure and improving the stress distribution conditions of the dam around the anchor cables. At the same time, the stress distribution of the arc section that acts as the "anchor end" is relatively uniform. It is conducive to the stability and safe operation of the dam structure. But at the same time, the length of the U-shaped anchor cable is more than double that of the...
