Abstract

The invention discloses a cast-in-place construction method of a corrugated steel web cantilever beam cast-in-place concrete bridge, and relates to the technical field of bridge construction, and the cast-in-place construction method of the corrugated steel web cantilever beam cast-in-place concrete bridge comprises the steps of field measurement, field pouring, maintenance and acceptance check. According to the method, the construction environment is measured on site, a corrugated steel web cantilever beam bottom film is manufactured, matched reinforcing steel bars and embedded parts are selected, the accuracy in the construction process is improved, bubbles in concrete are removed in the mode of using the vibrating bar and knocking the corrugated steel web cantilever beam bottom film, the concrete is maintained through a water spraying maintenance method, the quality of the concrete is improved, the concrete is sampled and detected in an equidistant sampling mode, inaccurate detection caused by accidental errors can be reduced, and the percent of pass of the concrete at all positions can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of bridge construction, in particular to a cast-in-place construction method for a corrugated steel web cantilever beam cast-in-place concrete bridge. Background technique [0002] Bridge construction is the process of building a bridge according to the design content; it mainly refers to bridge construction technology, construction organization, construction management, construction quality, etc. In the process of bridge construction, the cast-in-place construction process of cantilever beams with corrugated steel webs is an important link. [0003] But in the prior art, the cast-in-place construction method of most corrugated steel web cantilever girder cast-in-place concrete bridges causes the concrete quality of pouring to reduce because air bubbles easily exist in the concrete. Contents of the invention [0004] The purpose of the present invention is to provide a kind of cast-in-place construction m...
