Construction method for reinforced concrete arch bridge in soft soil foundation
A construction method for a reinforced concrete arch bridge in a soft soil foundation includes the following steps that step1, according to control over quality of a bored pile, pile foundation construction in a riprap region and pile foundation construction in a silt region are performed; step2, a deep foundation pit support structure is formed; step3, according to a formwork supporting system treatment scheme, a foundation changing and filling scheme is adopted for foundation treatment, and a full framing method is adopted for an upper portion structure; step4, curvature type quality control is achieved; step5, according to a concrete pouring sequence, arch structure concrete should be symmetrically poured, in order that pier columns of multiple-arch structures are prevented from bearing unbalanced horizontal thrust to the greatest extent, V-shaped pouring should be performed with the pier columns being the center, and in order to enable one cross structure to bear force symmetrically, pouring should be performed with the arch top being the symmetry from an arch legs to arch top. The construction method has good economic and social benefits and has popularization value.
