Embodiment
Embodiment:
Fig. 1-2 is referred to, the present embodiment shows a kind of assembled bellows enlarged footing anchor pole:
Including finish rolling deformed bar 1, flexible pouch 2, expand body section sleeve pipe 3, unidirectional grout pipe 4, one-way exhaust pipe 5, top Bearing plate 6, bottom bearing plate 7, taper are oriented to chapeau de fer 8, and finish rolling deformed bar 1 expands on body section sleeve pipe 3 through body section sleeve pipe 3 is expanded Pouch 2 is enclosed with, unidirectional grout pipe 4 and one-way exhaust pipe 5 are welded with top bearing plate 6, bottom bearing plate 7 has a cone below Shape is oriented to chapeau de fer 8.
Some supports 9 placed in the middle are provided with finish rolling deformed bar 1, the surface of finish rolling deformed bar 1 scribbles anti-corrosion asphalt paint.Expand Body section sleeve pipe 3 welds with top bearing plate 6, bottom bearing plate 7.Finish rolling deformed bar 1 passes through stress nut with expanding body section sleeve pipe 3 10 connections, stress nut 10 contact with being fixed on the thrust plate 11 of bottom bearing plate 7 below.Thrust plate 11 passes through thrust screw rod 16th, Thrust nut 17 is fixed on bottom bearing plate 7.
Top bearing plate 6 and bottom bearing plate 7 are respectively welded with pouch fixed cylinder 14, and flexible pouch 2 is solid by clips 15 Due in fixed cylinder 14.Top bearing plate 6 is welded with unidirectional grout pipe 4, one-way exhaust pipe 5, the slip casting inside flexible pouch 2 Unidirectional grout valve 12 is installed on pipe 4, one-way exhaust valve 13 is installed on the blast pipe 5 outside flexible pouch 2.Bottom pressure-bearing Plate 7 is provided below taper and is oriented to chapeau de fer 8, and taper, which is oriented on chapeau de fer 8, to be had into cement mortar hole.
