HDPE双壁波纹管施工方案的优化操作!

  HDPE双壁波纹管密度高,重量轻。聚乙烯双壁波纹管的密度为0.941-0.965,重量仅为钢管的八分之一,水泥管的十分之一。大大降低了运输安装成本和起重成本。PE双壁波纹管具有较强的耐化学腐蚀性能。优良便捷的施工时间——大大缩短了施工时间——省力——大大降低了施工强度——连接可靠性大幅度提高高密度聚乙烯(HDPE)具有优异的化学稳定性、耐老化和环境应力开裂功能。HDPE双壁波纹管属于柔性管。
  HDPE double-wall bellows have high density and light weight. The density of polyethylene double-wall bellows is 0.941-0.965, the weight of which is only one eighth of that of steel tubes and one tenth of that of cement tubes. The transportation installation cost and lifting cost are greatly reduced. PE double-wall bellows have strong chemical corrosion resistance. High-density polyethylene (HDPE) has excellent chemical stability, aging resistance and environmental stress cracking function. HDPE double-wall bellows belong to flexible tubes.
  HDPE双壁波纹管根部在插座与插座接口、机械连接等部位的沟槽内,应在铺设管道时随挖随放。槽的长度、宽度和深度可由管接头的尺寸决定。连接完成后,立即回填中粗砂。外壁为环形波纹结构,大大提高了管道的环刚度,增加了管道对土荷载的阻力。在这一功能上,HDP巨型双壁波纹管与其他管道相比具有显著的优势。本工程采用挖掘机开挖。基坑开挖应严格控制开挖深度和管道中心线。机械开挖余量为20cm。
  HDPE double-wall corrugated pipe roots in the socket and socket interface, mechanical connection and other parts of the groove, should be laid with the excavation of the pipeline. The length, width and depth of the groove can be determined by the size of the pipe joint. When the connection is completed, the medium and coarse sand should be backfilled immediately. The outer wall is a circular corrugated structure, which greatly improves the ring stiffness of the pipeline and increases the resistance of the pipeline to soil load. In this function, HDP giant double-wall bellows have significant advantages over other pipelines. Excavator excavation is used in this project. Excavation depth and pipeline center line should be strictly controlled in foundation pit excavation. The mechanical excavation allowance is 20 cm.

  双壁波纹管,不仅提高了电力的使用功率,增加了生产设备的安全性,hdpe双壁波纹管160,hdpe大口径波纹管降低了维修费用,并经常维修保养,双壁波纹管,还提供了清洁、安全的工作环境。地下室地面不透水的水,在地面上离地面,也就是说,做一层排水板是由地面之前,圆桌,留下一个盲沟附近,因此,地下水不来,通过排水板渗透自然空间到附近的盲沟,然后通过盲沟排水坑。规划建筑屋顶上种植美化,不仅解决了停车问题,并增加了美化城市乡村地区,现在城市建设是一种常见的方法,特别是在地下车库屋顶防水维护要求高,杂乱的环境,对耐腐蚀性能的需求,防止植物刺,防水维护,快速排水,土壤渗透性、保温的要求。如果这些问题得不到解决,许多问题将不可避免地在几年内出现。
  The double-wall bellows not only improve the power consumption of electric power, but also increase the safety of production equipment. The HDPE double-wall bellows 160 and the HDPE large-caliber bellows reduce the maintenance cost and often maintain. The double-wall bellows also provide a clean and safe working environment. The impermeable water on the basement floor is off the ground, that is to say, to make a drainage board is made by the ground before the round table, leaving a blind ditch nearby. Therefore, groundwater can not come, through the drainage board to infiltrate the natural space to the nearby blind ditch, and then through the blind ditch drainage pit. Planning and beautifying the roofs of buildings not only solves the parking problem, but also increases the beautification of urban and rural areas. Now urban construction is a common method, especially in underground garage roofs with high requirements for waterproofing and maintenance, chaotic environment, demand for corrosion resistance, prevention of plant thorns, waterproofing and maintenance, rapid drainage, soil permeability, etc. Requirements for thermal insulation. If these problems are not solved, many problems will inevitably arise in a few years.
  而且修葺不容易,造价昂贵,因此要保证栽培屋面的系统安全,必须考虑提高工程质量。排水,土工布具有突出的引水功能,它可以在土壤中形成排水通道,并将剩余的液体和气体从土壤结构中排出。一旦攻泡沟,应及时清理积水,软化土层,由气泡清除,更换填满砾石,在根部做好。施工过程中的测量主要是确定管道底部的高度。机械开挖后,选择管道底部测量,确保管道底部高度符合规划要求。管道安装后进行测量,及时处理问题,使管道底部高度控制在允许误差范围内。计量工作天天开始前,要进行相邻水平的校核计量。
  Moreover, repairing is not easy and the cost is expensive. Therefore, in order to ensure the safety of the roof system, we must consider improving the quality of the project. Drainage, geotextile has prominent water diversion function, it can form drainage channels in the soil, and the remaining liquid and gas are discharged from the soil structure. Once the bubble trench is broken, the water should be cleared in time, the soil should be softened, the bubbles should be cleared, the gravel should be replaced, and the roots should be done well. The measurement in the construction process is mainly to determine the height of the bottom of the pipeline. After mechanical excavation, the bottom of the pipeline should be measured to ensure that the height of the bottom of the pipeline meets the planning requirements. After installation, the pipeline is measured and the problem is handled in time so that the bottom height of the pipeline can be controlled within the allowable error range. Before the metering work begins every day, the adjacent level of checking and metering should be carried out.
