Bridge engineering construction method

Abstract

The invention discloses a bridge engineering construction method which comprises the following steps that S1 longitudinal and transverse center lines of a pier foundation and a platform foundation are measured by using a theodolite, and excavating is carried out according to excavation depth, soil texture and water seepage conditions; S2 supporting frames are arranged along the two sides of a road, the distance between every two adjacent supporting frames is 5 to 8 m, a protection plate is arranged between the two supporting frames, the two sides of the protection plate are fixed to the supporting frames, and a warning tape is arranged on the outer side of the protection plate; S3 according to a design drawing, the theodolite is used for accurately positioning a pile position, a rotary drilling machine is used for drilling, a pile body is driven in after drilling, a lower bearing platform and an upper bearing platform are sequentially poured on the pile body, and a pier column is poured on the upper bearing platform; and S4 hollow slabs are prepared according to needs, prestress testing is carried out, the hollow slabs are hoisted, a scaffold is built, continuous correction is carried out in the building process, a support and a beam formwork are installed, and layered pouring and continuous pouring are carried out through concrete. The construction efficiency can be improved, and safe construction can be guaranteed.

Description

technical field [0001] The invention belongs to the technical field of bridge construction, in particular to a bridge engineering construction method. Background technique [0002] At present, the construction method of the continuous beam of the existing bridge is: the construction of the continuous beam is carried out after the construction of the pier is completed. However, when the bridge is very high and the span is large, the disadvantages of this method are: the construction period of the bridge pier and bridge is long, there is only one working surface, and each process must be constructed in sequence, which seriously restricts the total construction period, and the error is large. Difficult to guarantee, resulting in repeated construction, further prolonging the construction week. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide a bridge engineering construction method, which helps to improve constructi...
