A prestressed anchor bolt tensioning construction technology

Abstract

The invention discloses a prestressed anchor bolt tensioning construction process. The construction process includes the following steps: drilling-corrugated pipe leveling-grouting-anchor installation; step 1: drilling, using an electric drill to open a foundation on the side of the road hole, the foundation hole is perpendicular to the road surface, put the lower anchor pad at the bottom of the foundation hole, and insert the bellows into the inside of the foundation hole, the bottom of the bellows is threaded with the lower anchor pad; step 2: leveling the bellows, Use the leveling mechanism to fix the upper part of the bellows, and the leveling mechanism uses the limit plate to fix and limit the bellows until the bellows is perpendicular to the road surface, pour concrete slurry into the foundation hole, and the concrete slurry is self-modulated to the bottom of the tank hole The duration is within 30 minutes. By adding a leveling step in the installation process of the corrugated pipe and the foundation hole, the corrugated pipe is leveled before pouring concrete slurry into the foundation hole, so that the corrugated pipe can be fixed vertically to the road surface, and the fixing process is more firm and less prone to damage. The slurry shakes after extrusion.

Description

technical field [0001] The invention relates to an anchor bolt construction technology, in particular to a prestressed anchor bolt tensioning construction technology, which belongs to the application field of anchor bolt construction. Background technique [0002] During the construction of the bridge, the bridge is often reinforced with cables to make it more stable in use, prolong its service life, and not easily damaged. The bottom of the cables is usually fixedly connected with the anchor bolts on the road or bridge surface. [0003] The Chinese patent with the application number 201110393062.X discloses a construction method for the suspended installation of structural anchor bolts, according to the anchor bolts and mold making → pile foundation reinforcement installation → anchor bolt positioning → anchor bolt installation → Finished product protection → concrete pouring process for construction. In this construction process, the process of connecting the bellows to t...

Problems solved by technology

[0005] The purpose of the present invention is to provide a prestressed anchor bolt tensioning construction process, which can solve the problem that the existing anchor bolt tensioning construction process cannot keep the bellows vertical to the ground, and the bellows is prone to produce tension after being pulled. Uneven force, bending and breaking
