Xuzhou Drain Pipe - Bridge Cast Iron Drain Pipe High speed Cast Iron Drain Pipe Manufacturer Production can be customized according to drawingsThe drainage pipes on the bridge pier are installed in advance below, and then connected to the drainage pipes on the top of the bridge pier through an automatic elevator.

　　Install drainage pipe supports, use a small electric drill to drill holes on the box girder and bridge pier, and install the drainage pipe supports. Generally, they should be installed every two meters, and special areas can be appropriately densified.

　　For the anti-collision guardrail in the deep part of the drainage pipe, the severely corroded and damaged drainage pipe should be chiseled out to the inside of the guardrail, ensuring that the PVC pipe penetrates the guardrail by no less than 10cm. The joint between the PVC pipe and the original drainage pipe can be bonded with high contact adhesive, and the PVC pipe and the protective fence should be fixed with mortar. For bridge piers located in ponds or other areas where automatic elevators cannot be placed, cranes should be used to cooperate, and the specific tonnage should be determined according to the actual situation on site.

　　The installation of the middle row of drainage pipes requires the installation of drainage pipes inside the box girder. Therefore, before installation, the drainage pipes and other materials need to be transported to the box girder. The drainage pipes can be lifted inside through the gap at the bridge pier, and the installation is the same as the drainage pipes on both sides.

　　Construction steps: Set up a work platform, clean (replace) the drainage pipe, install reinforcement and PVC pipe fittings for sealing, build the work platform and prepare for lifting the bearing platform. According to the determined construction plan, set up the work platform on the construction site, which should be firm and reliable to ensure the safety of construction personnel and bridge traffic. After installing all the drainage pipes, place the prefabricated C30 concrete slab below the outlet of the drainage pipe, mainly to prevent long-term erosion of the pier and abutment.

　　Installation of drain pipe bracket

　　Deep in the drainage pipe, the anti-collision guardrail should be horizontally (vertically arranged). The severely corroded and damaged drainage pipe should be chiseled out to the inside of the guardrail, ensuring that the PVC pipe is not less than 10cm deep into the guardrail. The joint between the PVC pipe and the original drainage pipe can be bonded with high contact type adhesive. A 5KW small diesel generator should be used to fix the gap between the PVC pipe and the protective guardrail with mortar, and a 3KW small electric drill should be driven to drill holes on the bridge. In principle, drainage pipe supports should be installed every two meters. Special parts can be appropriately densified, and drainage pipe supports should be installed.

　　The drainage pipe is a drainage system that connects with the drainage pipe to divert rainwater to the bottom of the bridge; A drainage pipe is a drainage system that is pre embedded on both sides or in the middle of a cast-in-place beam or prefabricated beam, as well as on the bottom plate, before pouring. This process is suitable for the installation and construction of drainage and drainage pipelines in railway bridges. Including installation of embedded parts, connection of drainage pipes, installation of pipe covers, installation of drainage pipes, etc.

　　Confirm the type and drainage method of the drainage pipe to be replaced on the construction site, and accurately measure the distance between the outlet and the two sides of the pier as the basis for cutting
