Stand column prefabrication construction process

Abstract

The invention provides a stand column prefabrication construction process. The stand column prefabrication construction process comprises the following steps of 1, selecting stand column steel bar machining equipment; 2, machining a grout sleeve; 3, conducting steel bar machining; 4, installing auxiliary equipment; 5, hoisting a stand column steel framework; step 6, machining a stand column sheet steel form; step 7, assembling the sheet steel form and putting the stand column steel framework into the sheet steel form; 8, installing a concrete pouring platform and pouring concrete; and 9, removing the sheet steel form and conducting concrete curing and storage. Compared with the prior art, the stand column prefabrication construction process has the following beneficial effects that the appearance quality and the inner quality of a prefabricated stand column, the accuracy of a connecting sleeve, the positioning accuracy of connected steel bars and the like are ensured, environmental protection is enhanced, the problem of labor difficulty is solved, the industrialization skills of workers are improved, and the construction period is shortened.

Description

technical field [0001] The invention is a column prefabrication construction technology, which belongs to the field of highway engineering. Background technique [0002] As the key to highways and municipal viaducts, bridges play an extremely important role. They have greatly improved the traffic network of highways and municipal viaducts, improved transportation capacity, promoted social and economic development, and brought great benefits to the majority of traffic participants. convenient. [0003] Many problems often arise in large-scale bridge construction. Among them, some bridge construction methods based on on-site concrete pouring construction mainly reflect the following problems: the ground and water area of ​​the bridge site have been occupied for a long time as a construction site, and traffic and other order in the construction area are seriously disturbed; construction equipment and auxiliary facilities are repeatedly configured, The consumption of resources...

Problems solved by technology

Among them, some bridge construction methods based on on-site concrete pouring construction mainly reflect the following problems: the ground and water area of ​​the bridge site have been occupied for a long time as a construction site, and traffic and other orders in the construction area are seriously disturbed; construction equipment and auxiliary facilities are repeatedly configured, The consumption of resources and energy is large, and the waste of financial and material resources is large; construction noise cannot be effectively controlled, construction sewage spills often occur, and surrounding residents and traffic participants complain a lot; accidental falling objects on site are inevitable, and the risk of construction and traffic accidents is high

When building a sea-crossing bridge in a marine environment with harsh weather conditions, there will be problems such as difficulty in pouring concrete on site, difficulty in ensuring construction quality and safety, high cost of fresh water transportation, and easy pollution of the marine natural environment.
