Abstract
The utility model relates to an improved hinge type large-tonnage anchor apparatus, comprising a hinge type large-tonnage anchor device A and a hinge type large-tonnage anchor device B. The back sides of the hinge type large-tonnage anchor device A and the hinge type large-tonnage anchor device B are both provided with limiting rings. Limiting holes are arranged on the limiting rings. One end of the hinge type large-tonnage anchor device A is provided with a groove. A revolution clamping slot at one end of the hinge type large-tonnage anchor device B is inserted into and connected with the groove through an interference fit latch so that the revolution clamping slot and the groove can rotate relative to each other around the interference fit latch. The diameter of the revolution clamping slot is 6 centimeters. According to the utility model, the hinge type large-tonnage anchor device A and the hinge type large-tonnage anchor device B are both relatively large in area, so that the bearing pressure of a grouting body is reduced under an unchanged pressure force. Based on the detection, the pressure can be reduced from 150 MPa to 63 Mpa. The pulling force of an anchor pole can be increased from a commonly used 700 KN to 1200 KN. At the same time, the diameter of the revolution clamping slot is 6 centimeters so that the revolution radius of a steel strand is increased and the strength breakage rate of the steel strand is low and around 8%. In addition, the anchor apparatus in the aforementioned structure can be conveniently inserted into a 147 sleeve pipe having an inner diameter of 11 cm.
