Embodiment Construction

[0056]The present invention is made in conjunction with the accompanying drawings and specific examples, but the scope of the invention is not limited thereto.

[0057]In the description of the present invention, it is to be understood that the orientation or positional relationship of the term "upper", "lower", "left", "right", "front", "post", etc. is based on the drawing. The orientation or positional relationship is intended to facilitate the description of the present invention, rather than indicating or implying that the device or element must have a particular orientation, and therefore, it is not understood as limiting the invention. The term "installation", "connection", "fixed", etc. should be broadly understood, for example, may be a fixed connection, or a detachable connection, or an integral connection, can be directly connected, or indirectly through an intermediate medium It is also possible to communicate inside the two components; for those skilled in the art, the abov...

Abstract

The invention provides a pier and beam integrated bridge girder erection machine and a hole passing construction method, and belongs to the technical field of bridge erection, the pier and beam integrated bridge girder erection machine comprises a longitudinal guide beam, a main beam, a crown block, four sets of support leg devices and a cross beam. The main beam is installed below the longitudinal guide beam, the cross beam is connected with the longitudinal guide beam, the crown block is installed on the cross beam, and the support leg devices are installed below the main beam. A carrier roller assembly and a hanging assembly are arranged on the support legs, the carrier roller assembly drives the main beam to move in the front-back direction, and the hanging assembly drives the support legs to move in the front-back direction. According to the machine, the pier columns and the split cover beams in the span are firstly installed, then hole passing operation is conducted to the next span to conduct pier column and cover beam hoisting operation, circulation is conducted, the pier columns and the split cover beams in the whole line are installed through one bridge girder erection machine, the problem that the wet connection waiting time of the split cover beams is long is solved, and the construction efficiency is high. Hoisting operation of pier columns, bent caps and box girders can be completed in an operation area with poor foundation bearing capacity, the foundation does not need to be reinforced, construction cost is low, and safety risks are low.

Description

Technical field[0001]The present invention belongs to the field of bridges, and more particularly to a pier girder integrated bridge and via construction method.Background technique[0002]Bridge prefabricated components are advanced technology in the construction of municipal highways, using factory prefabricated processing, more energy saving, green and environmentally friendly. Traditional bridge prefabricated components are lifted, multi-use car hang or crawler cranes, and have a greater demand for the ground base load, and more strict and strict in the inlet field, there are more restriction factors. Due to the smaller land construction of the municipal road bridge, it is prone to lifting safety accident during the construction process, and it will be difficult to remedy once there is a problem.[0003]The existing pier girder integrated bridge can integrate the pier, cover beam and tank girder to integrate, and a single machine can complete the hoisting operation of the correspond...
