Detailed description of the invention
Below specific embodiment of the utility model is described in detail, so that further understand this practicalityNovel.
Fig. 1 is the schematic diagram of prestress anchorage cable of the present utility model. Fig. 2 is 1-1 place cutaway view in Fig. 1.Fig. 3 is 2-2 place cutaway view in Fig. 1. Fig. 4 is 3-3 place cutaway view in Fig. 1.
As shown in Figure 1, a kind of prestress anchorage cable, is followed successively by stretch-draw section 1, free segment 2 from afterbody to endWith anchoring section 3. Wherein, stretch-draw section 1 is passed successively lattice girder 4 and is close to the grappling steel plate of lattice girder 411, and be connected with ground tackle 12 lockings on grappling steel plate 11 surfaces. Wherein, free segment 2 and anchoring section 3Be embedded in lattice girder 4 soil layer below. The front end sleeve in anchoring section 3 intervals is provided with the guiding cap 6 of wedge shape.Prestress anchorage cable also comprises and runs through first Grouting Pipe at free segment 2 centers and run through the of anchoring section 3 centersTwo Grouting Pipe. In work, termination sphenoid concrete must be built with perpendicular rib simultaneously. Above-mentioned ground tackle is preferably and makesWith 15-4 type ground tackle, but the utility model is not as limit.
Next, please also refer to Fig. 2-Fig. 4. As shown in the figure, prestress anchorage cable is many steel strand wires compositionsWire harness 5. Preferably, every bundle anchor cable adopts the high-strength low relaxed prestress steel strand of 4 bundle 7 Φ 15.2 to make.In work, when general steel wire, press design length 32m and calculate, and the stretch-draw section 1 of reserved 1m.
Wire harness 5 in stretch-draw section 1 interval can pass grappling steel plate 11, and locks onto on ground tackle 12. FromOuter surface by the wire harness 5 in section 2 intervals is arranged with sleeve pipe 21, and preferably, this sleeve pipe 21 isSmooth sleeve pipe.
