Abstract

The invention discloses a prefabricated prestressed anchor rod construction structure. The prefabricated pre-stressed anchor rod construction structure comprises a drill bit, a hollow primary anchor pipe and a hollow secondary anchor pipe, during use, the hollow mother anchor pipe can be fixed through mechanical equipment and driven to rotate, hole digging is conducted through a drill bit at the end of the hollow mother anchor pipe, after the hollow mother anchor pipe enters a hole, the hollow child anchor pipe is fixed through the mechanical equipment and pulled outwards, and the hollow mother anchor pipe is driven to rotate. The telescopic column of the hollow secondary anchor pipe is inserted into the second through hole of the hollow primary anchor pipe, axial fixation of the hollow secondary anchor pipe and the hollow primary anchor pipe is achieved, then the hollow secondary anchor pipe can be driven by mechanical equipment to rotate, hole digging continues to be conducted inwards, manual connection of the anchor pipes is not needed in the working process, construction efficiency is improved, interruption in the process is not needed, and construction efficiency is improved. And continuous automatic operation is realized.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a prefabricated prestressed anchor rod construction structure. Background technique [0002] In civil engineering slope reinforcement and urban deep foundation pit support projects, prestressed anchor rods are often used as the stressed components of the support structure. However, due to the limitations of site and geological conditions, it is inevitable to carry out prestressed anchor bolt construction in local bad geology and soil layers that are not easy to form holes. Existing prestressed anchor rods usually include structural components such as drill bits, hollow anchor pipes, centerers, and connecting sleeves. Install the drill bit on one end of the hollow anchor pipe, and use mechanical equipment to drive the hollow anchor pipe to rotate, so that the drill bit rotates to achieve drilling. If the length of a single hollow anchor tube is not enough, a centra...
