Construction method for newly building bridge substructure at existing underground pipe culvert
The invention discloses a construction method for newly building a bridge substructure at an existing underground pipe culvert. The construction method comprises the following steps that S1, a long pile casing is arranged in a drilled pile foundation hole opening, and concrete is injected into the long pile casing to form a pile foundation; s2, a box culvert of the drilled existing underground pipe culvert is constructed, and a waterproof structure and a water passing pipe penetrating through the waterproof structure are arranged; s3, bearing platform construction is conducted on the pile foundation; and S4, pier column construction is conducted on the bearing platform, and an underground pipe culvert is newly built on the other side of the bearing platform. Construction operation of a pile foundation is achieved by arranging the long pile casing, the situation that slurry in the long pile casing seeps to pollute the environment is prevented, and meanwhile hole collapse caused by the fact that water in an existing underground pipe culvert flows into the pile casing to dilute the slurry is also prevented; besides, a waterproof structure and a water passing pipe penetrating through the waterproof structure are arranged in the box culvert, water in the box culvert is prevented from flowing into a pile foundation, meanwhile, normal drainage in the current box culvert is guaranteed, and the municipal drainage problem after an existing underground pipe culvert is broken and before a new pipe culvert is built is solved.
本发明公开了一种在现有地下管涵处新建桥梁下部结构的施工方法，包括如下步骤：S1：在钻设的桩基孔口内设置长护筒，将混凝土注入长护筒内形成桩基；S2：对被钻开的现有地下管涵的箱涵进行施工，并在设置防水结构和贯穿防水结构的过水管；S3：在桩基上进行承台施工；S4：在承台上进行墩柱施工，并在承台的另一侧新建地下管涵。通过设置长护筒实现桩基的施工作业，防止长护筒内的泥浆渗出污染环境，同时也防止现有地下管涵内的水流入护筒内稀释泥浆造成塌孔；另外，在箱涵内设置防水结构和贯穿防水结构的过水管，防止箱涵内的水流入桩基内，同时保证了现状箱涵内的正常排水，解决了设在较现有地下管涵破除后、新管涵未建前市政排水问题。
