Construction method of anchorage anchoring system

Abstract

The invention discloses a construction method of an anchorage anchoring system. The construction method comprises the following steps of (1) constructing a well cover of a sinking well; (2) pouring concrete in a step area of an anchor beam bracket layer by layer; (3) installing the anchor beam bracket; (4) installing an anchor beam and an anchor rod bracket; (5) installing anchor rods and pouringanchor block concrete layers one by one; (6) continuing anchor block construction. According to the construction method, a mixed anchoring bracket system is formed, and a construction mode of installing the anchor rods during pouring is adopted at the same time. According to the method, the mixed anchoring bracket system is formed, the rigidity of the anchoring bracket is enhanced correspondingly,the cumulative deformation effect is eliminated, repeated operation caused by deformation of the bracket is effectively prevented, the construction efficiency is improved, the use amount of section steel is reduced, and the input cost is reduced.

Description

Technical field [0001] The invention relates to the field of bridge construction, in particular to a construction method of an anchorage system. Background technique [0002] In the process of bridge construction, the anchorage of anchorage generally adopts section steel anchor system and prestressed anchor system. Although section steel anchor system uses a large amount of steel, requires high production, installation and construction accuracy, and has a large amount of work, the system does not require post-maintenance It is a one-time investment and permanent use type without later investment. Therefore, from the perspective of the full life of the bridge, the section steel anchoring system has a strong advantage over the prestressed anchoring system, but the anchoring bracket of the section steel anchoring system generally adopts steel structure , Installed in place one by one, however, during the installation process of the section steel anchoring system, the steel structure...

Problems solved by technology

[0002] In the process of bridge construction, the anchorage of the anchor generally adopts the section steel anchorage system and the prestressed anchorage system. Although the section steel anchorage system uses a large amount of steel, requires high precision in manufacturing, installation and construction, and requires a large amount of work, the system does not require post-maintenance. , no need for later investment, it is a one-time investment and permanent use type. Therefore, from the perspective of the whole life of the bridge, the section steel anchorage system has a strong advantage over the prestressed anchorage system, but the anchor bracket of the section steel anchorage system generally adopts steel structure , installed in place in turn, however, during the installation process of the section steel anchorage system, the steel structure bracket is continuously raised, resulting in an increase in the flexibility of the overall anchor bracket, and at the same time, the force on the bracket continues to increase, and the cumulative deformation increases, resulting in the completion of the installation of the anchor system. The accuracy has changed many times and repeated adjustments will greatly affect the installation progress and consume a lot of manpower and material resources
