Nantong Drainage Board Manufacturer Backfill:
1, Backfilling should be carried out after the drainage pipeline (including pipes and inspection wells) has passed inspection and should be done simultaneously with the backfilling of the pipeline trench.KKolps33378
2, Before backfilling, sandbags, steel rods, and wooden supports can be used to secure the well base and well shaft, and water accumulation in the foundation pit and trench should be eliminated.156-2152-1000 Manager Shao
3, Backfill materials: Material used for backfilling in the trench from the bottom of the pipe foundation to 0.5m above the top of the pipe can include crushed stone, sand with a particle size of less than 40mm, high (medium) calcium powder fly ash, medium coarse sand, or good quality soil excavated from the trench.
4, Backfill soil must not include sludge, garbage, or frozen soil, and must not contain stones, bricks, or other angular hard objects.KKolps33378Nantong Drainage Board Manufacturer
5, In local areas where the depth of frozen soil is greater than or equal to 1.0m, medium coarse sand should be backfilled within at least 100m around the well shaft within the frozen layer.156-2152-1000 Manager Shao
6, Backfilling should be done manually in a symmetrical layered manner, with the same compaction as the pipe backfill, and must not cause displacement or tilting of the well shaft. Mechanical backfilling is strictly prohibited.Nantong Drainage Board ManufacturerKKolps33378
From deep to shallow, the basic construction steps, I estimate that reverse construction methods will not be used on municipal roads. In my opinion, road construction should pay attention to the following: firstly, the roadbed should be stable, as a sheet of paper can bear a thousand pounds, focusing on the compaction of the base layer; secondly, the edge formwork of the concrete pavement must be stable and sealed tightly; otherwise, when vibrating the concrete, issues such as bulging or leaking will arise, making the pavement look unappealing; thirdly, the flatness of the pavement is crucial; fourthly, for expansion and contraction joints, I believe the timing for cutting contraction joints must be well controlled, as concrete shrinkage can cause cracking in the pavement; fifthly, the mix ratio.
The purpose of the inspection well is primarily to facilitate the maintenance of urban underground infrastructure, including electricity supply, water supply, drainage, communications, cable television, gas pipes, and street lamp lines, for easy installation.Nantong Drainage Board Manufacturer.156-2152-1000 Manager Shao
They are generally set at the junctions of pipelines, at bends, where the diameter or slope changes, and at regular intervals along straight pipeline sections to facilitate regular inspection of auxiliary structures.
Drainage Volume:Nantong Drainage Board Manufacturer
According to statistics from 258 cities in China in 1983, the average daily volume of wastewater discharged from urban drainage pipelines is 57.46 million cubic meters, of which domestic sewage accounts for 13.45 million cubic meters, or 23.4%. The volume of domestic sewage depends on the amount of domestic water used. Most of the domestic water used eventually becomes domestic sewage discharged.
The rainwater runoff is related to the local heavy rainfall intensity, drainage area, and surface characteristics that generate runoff. The heavy rainfall intensity used in drainage pipeline design depends on the design recurrence period (the average number of years for a recurrence).
Therefore, the choice of the design recurrence period affects the technical and economic effectiveness of the project. If the value is too high, the designed rainwater runoff will be large, increasing construction costs. However, in important areas or regions where short-term water accumulation can lead to serious losses, a higher design recurrence period is advisable.
