Abstract

The invention discloses a road and bridge construction process, which comprises the following steps of: construction measurement: measuring a construction site for multiple times by using an engineering measurement tool, recording measurement data for multiple times, taking an average value of the measurement data for multiple times as the value of the measurement data , and drawing up a construction scheme; foundation construction: specifically, excavating a foundation pit according to the construction scheme, and then conducting pile foundation construction; abutment construction: specifically, after the pile foundation construction is completed, erecting an abutment support, installing abutment steel bar formworks, and pouring abutment concrete; upper structure construction: pre-buryinga steel bar frame on the abutment, pouring the steel bar frame by using concrete to form a cover beam, pre-burying steel bars for mounting a padstone above the cover beam, pouring the padstone through the pre-buried steel bars, mounting a padstone support in the middle of the upper surface of the padstone, and hoisting the box girder to the padstone support; bridge deck construction, conducting construction lofting, concrete pavement layer laying and pavement laying on the box girder in sequence. The purposes of improving the road and bridge construction process and improving the quality of the built bridge are achieved.

Description

technical field

[0001] The invention relates to the technical field of bridge construction, in particular to a road and bridge construction technology. Background technique

[0002] Bridges generally refer to structures erected on rivers, lakes, and seas to allow vehicles and pedestrians to pass smoothly. In order to adapt to the modern high-speed development of the transportation industry, bridges are also extended to cross mountains, poor geology, or meet other traffic needs to make traffic more convenient. building. However, the existing road and bridge construction technology is poor, and the quality problems of the built bridges are prone to occur. Contents of the invention

[0003] The purpose of the present invention is to provide a road and bridge construction technology, aiming to solve the technical problems in the prior art that the road and bridge construction technology is poor and the built bridge is prone to quality problems.

[0004] In order to achieve t...
