Abstract

The invention discloses a trestle construction method for bare rock geology. The trestle construction method mainly comprises the following steps of construction preparation, abutment construction, shore first pier enlarged foundation construction, first pier steel pipe pile construction, first construction platform construction, secondary pier structure foundation construction, secondary pier structure reinforcement construction, extension of a construction platform of the next stage and repeating of the steps. Meanwhile, common parts and construction methods thereof are optimized. And the trestle construction efficiency is improved. The method is applied to the field of trestle construction.

Description

technical field [0001] The invention relates to the field of trestle construction, in particular to a deep-water heavy-duty trestle construction method specially dealing with bare rock geology. Background technique [0002] Heavy-duty trestle: The trestle is an auxiliary temporary bridge structure temporarily built for transporting materials during engineering construction. It can cross rivers, lakes, seas or canyons. The span steel structure has a long service life and a high safety level. Among them, "heavy" refers to the large carrying capacity. [0003] Double-row brake piers of trestle bridges: brake piers refer to the piers that bear the horizontal thrust of all or a certain section of the bridge structure in the multi-span trestle bridge structure spanning rivers, lakes, seas or canyons. The braking pier is generally arranged in double rows and multi-rows with pier pipe piles, also known as double-row braking pier. The pier pipe piles are driven vertically into the ...
