Xinzhou Drainage Pipe Manufacturer - Production of Customized Cast Iron Drainage Pipes and PVC Drainage Pipes

Description :

　　Xinzhou Drainage Pipe Manufacturer - produces customized cast iron drainage pipes and PVC drainage pipes. When the bridge is located in a general outdoor area, the bridge deck drainage adopts direct drainage, that is, dispersed drainage. The dispersed drainage section does not have longitudinal drainage pipes on both sides. The longitudinal drainage pipe is only used for centralized drainage sections, and the bridge deck drainage pipe extends 10cm from the corresponding position at the bottom of the beam and slab

　　Do not install vertical drainage pipes or vertical drainage pipes for bridge piers. After the bridge deck water flows into the drainage pipes, it is directly discharged to the ground. two Centralized drainage is generally set up at bridge deck drainage points crossing highways, railways, villages, and adjacent towns. The drainage pipes are connected to the drainage pipes on both sides of the beam, and are led to the top of the pier at the outlet end along both sides of the beam and the bottom of the beam. Buffer the water through the downspout and then discharge it to the ground through the downspout. three The drainage system at the expansion joint (1) is designed to reduce the impact of accumulated water on the corrosion and aging of the expansion joint, and to prevent the formation of water flow along the bridge direction in ballastless track bridges. Install a centralized drainage device at the expansion joint to divert water from the expansion joint and introduce it into the bridge deck drainage system through drainage pipes. (2) Each end of the beam is equipped with a middle drainage pipe and an expansion joint drainage pipe. The expansion joint drainage pipe is led to the top of the pier and connected to the middle drainage pipe at either end of the beam. If the beam needs to be equipped with drainage pipes on both sides, the drainage pipes on both sides and the expansion joint drainage pipe are connected to the middle drainage pipes at both ends of the beam

4. Drainage at the middle of the beam end (1) The accumulated water between the rail supports is led to the bottom of the beam through the beam end drainage pipe, which is connected to the beam bottom drainage pipe. The collected water is buffered at the top of the pier and then discharged to the ground through the downspout. (2) If the beam needs to be equipped with drainage pipes on both sides, the drainage pipes on both sides and the expansion joint drainage pipe should be connected to the middle drainage pipe at the end of the beam and collected together into a drainage bucket. (3) During the installation of drainage pipes, high-altitude hazardous operations should be minimized or avoided as much as possible, and a portion of the pipeline installation should be completed in the precast beam yard as much as possible. For example, vertical centralized drainage pipes can be installed uniformly in the beam yard, and then the pipes connected to the ground can be installed after the installation is completed, greatly saving installation costs and reducing the difficulty of construction and installation, especially for cross line construction. If the beam is cast in situ with brackets, the drainage pipes can be directly installed when the brackets are removed, which will also reduce the waste of labor and materials caused by re erection construction afterwards. (4) The installation of drainage pipes is based on the requirements of the drawings, and the centralized drainage outlets on both sides are related to the slope of the bridge deck. The outlets are located at the downhill end. The drainage pipe itself also has a slope, which facilitates the drainage of flat slope beams. During construction and installation, attention should be paid to the outlet. (5) The installation of drainage pipes is carried out through specially designed mobile hangers or steel pipe racks. First, hanging brackets and fixed supports for downspouts are installed. Generally, supports are set every 1.5 meters, and their positions can be adjusted according to actual needs; Another step is to install pipelines; Tighten the hanging bracket and the fixed bracket for the downspout with bolts. 5、 After installing the drainage pipe and drain pipe, plug the outlet of the drain pipe with filling material. After the bridge deck construction is completed, remove the filling material and install the pipe cover. 12.1.6 Construction Machinery and Process Equipment The main machinery used for construction includes: engineering transport vehicles, cranes, process equipment such as stairs, cutting machines, adhesives, wrenches, handrails, steel pipe racks or steel hangers. 12.1.7 Operation Organization 1 In bridge construction, the drainage pipe is a single and important task that does not require too much labor. However, it is an indispensable component of the bridge and must be taken seriously. It cannot be forgotten or installed arbitrarily. Special personnel are responsible for installation and inspection. Improper installation can easily lead to water seepage and corrosion of the surface concrete of the bridge.
