Double-wet-joint segment prefabricated bridge assembling linear adjusting device

Abstract

The invention belongs to the technical field of bridge engineering, and discloses a double-wet-joint segment prefabricated bridge assembling linear adjusting device which is used for linear adjustmentof assembling between a prefabricated segment beam to be assembled and a pier top segment beam. Pier top section beams at two ends of the prefabricated section beam to be assembled are a first pier top section beam and a second pier top section beam respectively. The device comprises a plurality of telescopic actuating devices arranged at a joint portion between the prefabricated segment beam tobe assembled and the first pier top section beam a power system electrically connected with each telescopic actuating device, and a data analysis system which is in a signal connection with the powersystem and a measurement system which is in the signal connection with the data analysis system, wherein the telescopic actuating devices are respectively arranged at a roof plate position of the piertop section beam and an intersection position between a bottom plate and a web, and a telescopic end of the telescopic actuating device is connected with the prefabricated section beam to be assembled and can drive the prefabricated section beam to be assembled to move. And the telescopic end of the telescopic actuating device drives the prefabricated section beam to be assembled to be connectedwith the pier top section beam in the XY plane and the XZ plane.

Description

technical field [0001] The invention relates to the technical field of bridge engineering, in particular to a line shape adjustment device for prefabricated bridge assembly of double wet joint segments. Background technique [0002] The key to segmental prefabricated bridges is alignment control, which includes two parts, prefabricated alignment and assembled alignment. The control accuracy of the prefabricated alignment can ensure that the local alignment between segments meets the requirements, and the core of the assembly alignment control is to ensure that the overall alignment meets the requirements, as shown in the attached figure 1 As shown, for the segmental prefabricated bridge with double wet joints 2 and 3, after the segmental matching prefabrication is completed, the local alignment between the prefabricated segmental beams 1 to be assembled has been controlled by the prefabrication stage, which can be regarded as the prefabricated The segment beam 1 is a whole....

Problems solved by technology

[0007] Option 1) Because gaskets are installed between segments, it will greatly affect the durability of joints between segments, and even cause local stress on concrete segmental beams due to improper gasket settings, resulting in uneven stress on segments. cracking or partial crushing

[0008] Option 2) The requirements for the bridge erecting machine are very high, and the bridge erecting machine is required to be able to move in three directions under load, and it is highly dependent on the erection equipment, such as the deformation of the bridge erecting machine during the erection process, and the accuracy of the three-way movement of the bridge erecting machine Control, etc., will greatly affect the accuracy of assumptions. If the operation is improper, it may even cause the overall displacement, tilt, and collapse of the bridge erecting machine, resulting in accidents.
