The invention reLates to an anti-coLLision guardraiL based on an integraL hanging mouLd cast-in-pLace concrete waLL and a construction method. The guardraiL comprises a box girder, a waLL type anti-coLLision guardraiL and an integraLLy tied reinforcement cage, the box girder is provided with a reserved main rib temporary jack and a temporary verticaL puLL-and-puLL rod fixing groove; the main rib of the integraLLy tied reinforcement cage extends into the reserved main rib temporary jack; the integraLLy tied reinforcement cage is fixed on the box girder through an L-shaped Lattice type reinforcement cage fixing frame; the integraLLy tied reinforcement cage is weLded on the L-shaped Lattice type reinforcement cage fixing frame, an integraL embedded bracket is arranged in the integraLLy tied reinforcement cage, and a moving hanging basket is arranged at the outer side of the box girder; a fixed forming inner moLd and a moving forming outer moLd are arranged on the outer side of the waLL type anti-coLLision guardraiL, and the upper end pLates of the frameworks are arranged on the upper parts of the fixed forming inner moLd and the moving forming outer moLd. The box girder has the advantages that the reserved main rib temporary jack and the L-shaped Lattice type reinforcement cage fixing frame are arranged on the box girder, and are used for fixing the integraLLy tied reinforcement cage and ensuring the safety of construction.
Description
technical field [0001] The invention relates to a cast-in-place concrete wall-type anti-collision guardrail and a construction method, in particular to a cast-in-situ concrete wall-type anti-collision guardrail based on an integral hanging form and a construction method. Background technique [0002] In recent years, with the rapid development of my country's urban and rural economies, road construction has also developed rapidly. As a very important functional structure in municipal roads, bridges play a decisive role in improving the urban traffic environment and promoting regional economic development. Moreover, people pay more and more attention to the artistry of bridges, and have higher requirements for bridge aesthetics. As an important part of the auxiliary facilities of the bridge, the anti-collision wall is not only a safety protection structure to ensure driving safety, but also a carrier of street lamps and road signs, and it is also a window that directly shows p...
