　　In 1983, according to statistics from 258 cities in China, the daily average amount of sewage discharged through urban drainage pipes was 57.46 million cubic meters, of which 13.45 million cubic meters were domestic sewage, accounting for 23.4%. The amount of domestic sewage depends on the amount of domestic water used. During the use of domestic water, the vast majority is discharged as domestic sewage. Rainwater runoff is related to local rainstorm intensity, catchment area and surface characteristics of runoff generation. The rainstorm intensity used in the drainage pipeline design depends on the design return period (the average number of repeated occurrences). Therefore, the value of the design recurrence interval affects the technical and economic effects of the project. The value is too high, and the designed rainwater runoff is large, which will increase construction investment. But in important areas or areas where short-term waterlogging can cause serious losses, the design return period should be set at a higher value.

　　The inner diameter of the drainage pipe is generally between 0.10 and 0.15m,

　　Product use: Vertical and horizontal drainage and permeability of highways

　　Basic Introduction

　　English name of drainage pipe: drainage pipe

　　Definition 1: Mainly used for railway bridge drainage, bridge guardrail supports on both sides of highways, and engineering and chemical sewage systems.

　　Definition 2:1 The construction of drainage pipes should be carried out according to the design requirements. The drainage pipes should protrude from the bottom of the structure by no less than 30mm, and the longitudinal spacing should not exceed 4m.

　　2. For overpasses and bridges on highways, the drainage pipe should not be directly hung under the slab. The drainage pipe can be directly led to the ground through longitudinal and vertical drainage pipes.

　　Performance Characteristics

　　1、 Drainage safety: The orifice is located in the valley, and due to the bidirectional effect of the wave crest and the filtering fabric, the orifice is not easily blocked, ensuring smooth flow of the permeable system.

　　2、 The organic combination of strength and flexibility: The unique double corrugated structure effectively improves the external pressure strength of the product, and the drainage system will not be affected by external pressure deformation and affect the drainage effect.

　　3、 Economy type: Compared with other drainage pipes of the same diameter, its selling price is lower.

　　Product Usage

　　1. Vertical and horizontal drainage and permeability of highways;

　　2. Vertical and horizontal drainage on the back of various retaining walls and side ditches on highways;

　　3. Drainage of tunnels and underground passages;

　　4. Water supply and drainage for municipal engineering, water treatment plants, sewage treatment plants, garbage dumps, etc;

　　5. Drainage of rest green spaces such as golf courses, sports fields, and parks;

　　6. Soil and water conservation for slope development in mountainous areas;

　　7. Underground drainage for land preparation projects;

　　Cast iron drain pipe, suitable for paving structures with waterproof layers. The inner diameter of the drainage pipe is generally 0.10-0.15m, and the lower end of the pipe should extend at least 0.15-0.20m below the bottom of the roadway slab to prevent moisture from seeping into the surface of the main beam ribs.
