Embodiment Construction
[0036] Attached to the following Figure 1-5 This application will be described in further detail.
[0037] The embodiment of the present application discloses a prefabricated abutment structure, refer to figure 1 and 2 , including the abutment body 1, the abutment body 1 is composed of a steel cage 11, a steel sleeve 12 and poured concrete; the steel sleeve 12 is in the middle of the steel cage 11, and the steel cage 11 and the steel sleeve 12 are fixed by stirrups Connection: After the steel sleeve and the steel cage 11 are connected, the formwork 2 is built, and concrete is poured into the steel cage 11 to form a prefabricated abutment after solidification.
[0038] refer to Figure 1-3 , wherein, in order to ensure that the steel casing 12 is offset during the concrete pouring process, a positioning column 3 is vertically fixed in the middle of the formwork 2 at the bottom, and the positioning column 3 is smaller than the inner diameter of the steel casing 12; in this e...

The invention relates to a prefabricated bridge abutment structure and a construction method, and relates to the technical field of bridge construction. The bridge abutment comprises a bridge abutment body, the bridge abutment body comprises a steel reinforcement cage and a steel sleeve fixed to the steel reinforcement cage, and the bridge abutment further comprises a positioning mechanism arranged in the steel sleeve. The positioning mechanism comprises a plurality of groups of guide wheels which are distributed along the circumference of the steel sleeve at equal intervals, and a transmission part which correspondingly drives each group of guide wheels to move along the radial direction of the steel sleeve. The method has the effects that the positioning accuracy of the steel sleeve is improved, and subsequent connection of the bridge abutment and the pile foundation is facilitated.
Description
technical field [0001] The present application relates to the field of bridge construction technology, in particular to a prefabricated abutment structure and construction method. Background technique [0002] The abutments, located at both ends of the bridge, support the superstructure of the bridge and connect with the embankment. Its function is to transfer the load of the superstructure of the bridge to the foundation. [0003] In the related art, the bridge abutment is prefabricated, which is formed by pouring steel cages and concrete, and in order to facilitate the connection between the bridge abutment and the pile foundation, during the prefabrication process of the bridge abutment, a height equal to the thickness of the bridge abutment will be fixed inside the steel cage. When connecting the bridge abutment to the pile foundation later, it is only necessary to sleeve the steel sleeve on the pile foundation, and then pour concrete between the pile foundation and the ...
