Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is further detailed.
See accompanying drawing 1-4, the present embodiment comprises anchorage of rubber dam bag groove 1, the steel fibrous concrete front wedge 2 be arranged in anchorage of rubber dam bag groove 1, steel fibrous concrete back wedge 3, last item 4 and be located at the anchored end of the bottom spacer 6 in base plate anchor slot; Described anchorage of rubber dam bag groove 1 section configuration is the rectangular channel of side band fluted 9, and described last item 4 is arranged in groove 9, and described last item 4 place is provided with dam bag 5 and bottom spacer anchored end; Be positioned at above described steel fibrous concrete front wedge, back wedge and be provided with pea gravel concreten layer 8 in described anchor slot 1.Described last item 4 is hardwood, rubber bar, steel pipe or reinforcing bar.
Described anchorage of rubber dam bag groove 1 height H (width is also H, and both are measure-alike, shown in Fig. 2) is 1/10 of dam bag height, and anchorage of rubber dam bag groove 1 height H is not less than 220mm; The length L of described groove 9 is its width of 30 ~ 60mm(L is also 30 ~ 60mm).Described steel fibrous concrete front wedge 2 section configuration is at right angles trapezoidal, the few 20mm of aspect ratio anchor slot 1 height H, and the inclination angle on inclined plane is β=12 ° ~ 16 °, and length is 500 ~ 600mm; Described steel fibrous concrete back wedge 3 section configuration is at right angles trapezoidal, the few 40mm of aspect ratio anchor slot 1 height H, desirable α=12, inclination angle on its inclined plane ° ~ 16 °, and length is 225 ~ 275mm; One piece of corresponding 2 pieces of steel fibrous concrete back wedge 3 of steel fibrous concrete front wedge 2 is evenly arranged.The scale error of anchor slot and steel fibrous concrete wedge is all not more than 2mm.
