Abstract:
The present invention relates to a bridge drainage facility capable of treating initial rainwater, an initial rainwater inducing method using the drainage facility, and a non-point pollution reducing facility and a method thereof comprising the drainage facility. More specifically, the present invention relates to a bridge drainage facility for inducing initial rainwater generated from a bridge on a river to a non-point pollution reducing facility, which comprises a vertical pipe in connection with a catch pit installed on one side of a road on the bridge; a longitudinal drainage pipe which is connected to both end parts of the vertical pipe respectively, is installed to a reducing facility installed on a ground part of an abutment, and induces the collected initial rainwater to the reducing facility; an overflowing pipe which is installed on one side of each of the vertical pipes, receives excessive water whose amount exceeds the capacity of the longitudinal drainage pipe except for the initial rainwater of the rainwater collected in the vertical pipe, and drains the excessive water to the river, wherein the overflowing pipe is shaped into a curved ��shape, and the length of the vertical pipe is 200 to 450 mm.

본 발명은, 교량의 교각연결용 기초 시공방법에 관한 것이다. 이는 특히, 각각의 교각과 대응되도록 교각과 적어도 동일한 직경을 갖도록 지면에 기둥기초를 굴삭한후 그 내측에 철근을 설치하고, 상기 철근이 설치되는 기둥기초의 내측에 콘크리트를 타설하며, 상기 기둥기초의 상부에 교각을 연결하는 구성으로 이루어 진다. 이에따라서, 푸팅및 다수의 항타말뚝시공 공정을 배제시킴으로써 주변지반의 교란을 최소화 하고, 시공시 소음진동을 최소화 하며, 충분한 근입심도를 유지하도록 하는 것이다. 기둥기초, 교각, 철근, 교량, 굴착
