Abstract

The invention relates to a composite bearing plate capable of enhancing a front grouting body and a rear grouting body. The composite bearing plate comprises a bearing plate body, a central hole and rib penetrating holes are formed in the bearing plate body, the composite bearing plate further comprises a pipe joint hole formed in the bearing plate body, a double-headed screw connection pipe is arranged in the pipe joint hole in a penetrating mode, a first end and a second end are arranged at the two ends of the double-headed screw connection pipe in the axial direction, a bearing section pipejoint is connected to the first end in a threaded mode, and a tension section pipe joint is connected to the second end in a threaded mode, holes communicating with the inner wall of the bearing section pipe joint are formed in the side wall of the bearing section pipe joint, holes communicating with the inner wall of the tension section pipe joint are formed in the side wall of the tension section pipe joint, an end sealing plate is arranged at the end, away from the double-headed screw connection pipe, of the tension section pipe joint, and a reinforced grouting pipe is connected to the end, away from the double-headed screw connection pipe, of the bearing section pipe joint. The invention further provides an anchor rod adopting the composite bearing plate. According to the technical schemes, soil scraps or soil slag in a certain range before and after the bearing plate can be purified, and the strength of the front grouting body and the rear grouting body of the bearing plate is greatly improved.

Description

technical field [0001] The invention relates to a combined pressure bearing plate and anchor rod capable of strengthening front and rear grouting bodies. Background technique [0002] The tensile-compression composite anchor (as disclosed in Patent No.: ZL201420450678.5) has significantly improved bearing capacity and greatly reduced engineering cost, and has been applied in practical projects one after another. The tension-compression composite bolt technology has broad application prospects in anchoring projects such as slopes, foundation pits, water conservancy, dams, mines, and underground engineering. [0003] One of the mechanisms for the significant increase in the bearing capacity of the tension-compression composite bolt is that the large concentrated load transmitted from the anchor head to the bearing plate is decomposed into two small concentrated loads by the action of the bearing plate. Tension anchorage shared. In front of the pressure plate, the grouting bo...
