Abstract

The invention provides a porous large-section cast-in-situ box girder and a construction method. The method comprises the following steps that 1, foundation treatment is conducted, specifically, stepsare excavated on an original foundation, and mortar plastering construction is conducted by adopting a Z-shaped dragging sliding device for carrying out foundation construction; 2, a support is set,specifically, after the foundation reaches a certain strength, a support system is set up; 3, a bottom die is mounted, and specifically, the bottom die of the box girder is mounted; 4, the support ispre-pressed, and specifically, the support system is pre-pressed by using a water bag; 5, an inner die is mounted; 6, box girder construction is conducted; 7, a box girder formwork is removed; and 8,the support system is removed. Aimed at the porous large-section cast-in-situ box girder ultrahigh full framing system construction method, the engineering cost is effectively reduced, the construction speed is accelerated, and the good technical economic benefits can be achieved by applying the method to practical engineering.

Description

technical field [0001] The invention relates to the field of civil engineering, in particular to a porous large-section cast-in-place box girder and a construction method, which are suitable for the construction of a super-high full-height support system of a porous large-section cast-in-place box girder. Background technique [0002] With the rapid development of social economy, bridge engineering has become the focus of people's attention. At this stage, the role of highway bridges in our country in social and economic development is becoming more and more prominent. People are more concerned about the style, structure and aesthetics of continuous bridges. requirements are also increasing. With the development of science and technology in our country, the construction technology of continuous box girder construction is also changing with each passing day. [0003] At present, during the construction of box girders, problems such as difficult construction quality control o...
