Abstract

The invention provides a bridge temporary support which comprises an adjustable support and a supporting frame, and the adjustable support is located at the top of the supporting frame and used for adjusting the horizontal height of a bridge segment installed on the temporary support. According to the temporary support of the bridge, the calibration speed of the bridge subsections can be increased, the course closure time in bridge construction is shortened, and meanwhile deformation caused by differential settlement after closure of the bridge subsections can be eliminated. Meanwhile, the invention further provides a construction method of the bridge.

Description

technical field [0001] The invention relates to the technical field of municipal bridge engineering construction, in particular to a bridge temporary support and a construction method. Background technique [0002] The segmentation positioning of existing long-span steel structure bridges is divided into preliminary positioning and precise positioning. Such as figure 1 As shown, the preliminary positioning is carried out by the crane ship. Two pairs of limit plates 3 should be preset on the two sets of temporary supports 1 at both ends of the bridge segment 2. The limit plates 3 are used to limit the position where the bridge segment 2 will be placed. Then the bridge section 2 is roughly moved in place, and the gap between the limiting plate 3 and the bridge section 2 is controlled at about 5-10cm. Accurate positioning adopts three-dimensional adjustment method, that is, under the condition that the crane ship does not loosen the hook, the movable jack is used to carry out...
