Abstract

The invention discloses a self-lifting sliding and turnover construction system and a construction method. The system comprises a framework type combination crown block hanging bracket device and a semi-automatic turnover device. The construction method comprises steps as follows: construction of reinforcing steel bars of a pier body, large-area formwork bracket splicing, sliding formwork bracket splicing, self-lifting hanging bracket splicing, concrete pouring, sliding formwork bracket sliding rising, large-area formwork turnover and next stage of reinforcing steel bar construction. A self-lifting technique can be adopted, auxiliary construction by mechanical equipment such as a tower crane, a truck crane and the like can be omitted, high-pier construction is realized with the self-lifting technique, and the method guarantees the construction speed of a sliding formwork and the appearance quality of a turnover formwork without relying on external machines.

Description

technical field

[0001] The invention belongs to the field of bridge construction, and in particular relates to a self-elevating and slipping construction method. Background technique

[0002] my country's highway industry is changing with each passing day. For regional economic development, more expressways extend into deep mountains, or cross rivers, lakes, rivers and seas. Therefore, the design of high piers in bridge engineering is very common. At present, there are usually three types of high pier construction in my country: turning formwork, sliding formwork, and climbing formwork. In view of the high construction technology requirements and high construction costs of climbing formwork, climbing formwork is mostly used in super-large bridge main pier projects, and the number is more Many ordinary high piers are usually constructed by overturning or sliding form. However, the overturning and sliding form construction methods have the following problems:
