Electrified railway existing bridge and culvert whole-hole moving-out construction method
The invention provides an electrified railway existing bridge and culvert whole-hole moving-out construction method, which comprises the following steps that a flagstone foundation is formed through building flagstones under an existing railway bridge; a tension pile is arranged in foundation soil; earthwork is used for filling between the flagstone foundation and the tension pile for forming an earthwork filling layer; a concrete side slag blocking wall is cast; a beam conveying rail is paved and fixed; the whole-hole beam plate moving-out is carried out in a construction operation site; stone ballasts are filled back, a railway route is recovered and the like. The electrified railway existing bridge and culvert whole-hole moving-out construction method provided by the invention has the advantages that the condition that the normal use of a railway power supply system is not influenced in the beam plate dismounting process can be ensured, in addition, each hole beam plate on the railway bridge can realize the integral one-step dismounting, the rail-way sealing construction time is shortened, in addition, the construction is convenient, the safety is higher, the construction period is short, and the construction cost is low.
