Abstract

The invention provides a bridge arch foot supporting device and a construction method thereof. The device comprises a supporting frame, a first supporting mechanism and a second supporting mechanism, wherein the bottom end of the supporting frame is connected with a bearing platform of an arch foot to be supported; a lower chord of the arch foot to be supported is connected with the supporting frame through the first supporting mechanism; and an upper chord of the arch foot to be supported is connected with the supporting frame through the second supporting mechanism. The first supporting mechanism in the bridge arch foot supporting device is connected to the lower chord of the arch foot to be supported, and the second supporting mechanism is connected to the upper chord of the arch foot to be supported; furthermore, the first supporting mechanism and the second supporting mechanism are both connected with the supporting fame, so that the arch foot to be supported is pre-buried through a rigid fixing measure to ensure that no displacement and deflection are caused on the angle and the position of the arch foot to be supported during crossing construction of the arch foot to be supported before civil engineering pouring, and the installation angle and locating coordinates are guaranteed; and moreover, the time for adjusting the arch foot to be supported is also saved, and the construction efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to a bridge arch foot support device and a construction method thereof. Background technique [0002] The under-supported inverted triangular steel tube concrete truss arch bridge has an inverted triangular cross-section of the arch rib and is composed of multiple steel tube chords. The arch rib adopts embedded structure and is fixed on the concrete abutment, and the abutment adopts reinforced concrete structure, and the interface gradually changes from the trapezoid at the end of the arch to the rectangle at the end of the beam. The arch rib is divided into three sections according to the pre-embedded and non-embedded sections. The pre-embedded section of the arch rib at both ends is called the arch foot, and the non-embedded section in the middle is called the middle section. The arch foot section is composed of two parts, one part needs to be pre-buried in the abutment...
