Construction method and structure of assembly anchor rod frame beam

Abstract

The invention discloses a construction method and structure of an assembly anchor rod frame beam. The construction method is characterized in that an existing integral cast anchor rod frame beam is decomposed into two different prefabricated parts, namely cross prefabricated parts and sealing head prefabricated parts; during specific construction, the side slope protection working efficiency is improved by adopting a field assembly manner, and the side slope protection working efficiency is close to the side slope excavation working efficiency, so that the specification requirement for simultaneous excavation and protection of a side slop from top to bottom is achieved. According to the method, the prefabricated parts can be concentrated and prefabricated in a professional prefabricated field and then transported to a construction site for assembly construction, and due to the fact that formworks does not need to be erected as in the prior art, pouring of concrete and the time for waiting for the concrete to be consolidated are not needed, the side slope protection working efficiency is greatly improved. Therefore, requirements of side slope protection safety codes are met, the construction of simultaneous excavation and protection can be carried out from top to bottom, and the safety risks of landslides and falling objects to injure people are reduced.

Description

technical field [0001] The invention relates to a construction method and structure of an assembled anchor bar frame beam, belonging to the technical field of roadbed slope protection. Background technique [0002] According to the safety specification for slope protection construction, the first level of protection should be excavated from top to bottom to ensure construction safety. But what the slope protection construction of prior art adopted is the integral pouring type anchor bar frame beam. It is necessary to drill the anchor rod or anchor cable hole on the excavated slope first, then fix the anchor rod or anchor cable in the hole, then support the formwork on the slope, and bind the steel bars in the formwork, and finally use the concrete The pouring method integrates the concrete frame beam with the anchor rod or anchor cable to form an anchor rod or anchor cable frame beam. construction. If the construction is carried out in full accordance with the slope prote...

AI Technical Summary

Problems solved by technology

After the slope is excavated, due to the destruction of the surface soil structure, the risks of landslides and falling objects from heights are particularly prone to occur, which will cause safety risks of construction personnel casualties, and the quality of graded construction projects is not easy to control

Therefore, there are still deficiencies in the existing technology
