塑料检查井的特点

Characteristics of Plastic Inspection Well

塑料检查井是连接雨水、污水排放塑料管道以及供养护工人或设备检查、清除异物的附属构筑物,对于自动化或半自动化定期检查和疏通管道极为方便。它与塑料管道、配件共同组成了一个流通性能好、密封性强、使用寿命长、施工安装便捷,节材省地的环保排污管道系统。塑料检查井以高分子树脂塑料为原料,采用组合结构,典型结构。一般由井座、井筒、井盖、盖座和混凝土支撑板（必要时）等组成,选用相应的变径接头、可变角接头及密封圈等配件。

Plastic inspection wells are accessory structures connecting plastic pipes for rainwater and sewage discharge, and for maintenance workers or equipment to inspect and remove foreign bodies. They are very convenient for automatic or semi-automatic periodic inspection and dredging pipes. Together with plastic pipes and fittings, it forms an environmental protection sewage drainage pipeline system with good circulation performance, strong sealing, long service life, convenient construction and installation, and saving material and land. Plastic inspection wells are made of macromolecule resin plastics and adopt combined structure and typical structure. Generally, it is composed of well seat, well bore, well cover, cap and concrete support plate (if necessary). Corresponding variable diameter joint, variable angle joint and sealing ring are selected.

它具有如下特点：

It has the following characteristics:

1） 所采用的塑料为热塑性塑料,加工耗能低,同时环保节能、耐腐蚀、使用寿命长。

1) The plastics used are thermoplastics with low energy consumption, environmental protection, energy saving, corrosion resistance and long service life.

2） 塑料检查井采用工厂化生产,产品尺寸精确,质量稳定,生产周期快且制作过程不受现场条件如气候、地质的影响。

2) Plastic inspection wells are manufactured in factories with accurate product size, stable quality, fast production cycle and production process not affected by site conditions such as climate and geology.

3） 塑料检查井与塑料排水管道使用相同的塑料材质,相同的基础形式，相同的接口形式,可以有效地解决管道与井的连接问题。

3) Plastic inspection wells and plastic drainage pipes use the same plastic material, the same basic form and the same interface form, which can effectively solve the connection problem between pipelines and wells.

4） 可采用弹性密封圈连接或胶粘剂粘接,避免了不均匀沉降对管道造成的破坏,大大提高了管道和井的抗渗性、密封性,有利于排水管道长期安全使用,也避免了地下水的二次污染,安全环保。

4) Elastic sealing ring connection or adhesive bonding can be used to avoid the damage caused by uneven settlement of pipelines, greatly improve the impermeability and sealing of pipelines and wells, which is conducive to the long-term safe use of drainage pipelines, and also avoid the secondary pollution of groundwater, safety and environmental protection.

5） 安装操作简便,施工速度快,塑料检查井的施工安装都较传统砖砌检查井简便,从基础施工到井体安装、连管安装、防沉降大盖板安装的施工周期较砖砌井成倍地缩短,这就解决了以往塑料排水管道施工中普遍存在的“管道施工快,但检查井施工慢”的问题。只有当管道检查井的施工速度也相应提高,才能充分体现塑料排水管道施工方便快速的优越性。

5) Installation operation is simple, construction speed is fast, construction and installation of plastic inspection wells are simpler than traditional brick inspection wells. Construction period from foundation construction to wellbore installation, connecting pipe installation and installation of large anti-settlement cover plate is twice shorter than brick construction wells, which solves the common problem of "pipeline construction is fast, but construction of inspection wells is slow" in plastic drainage pipeline construction. Only when the construction speed of pipeline inspection wells is increased correspondingly, can the advantages of convenient and fast construction of plastic drainage pipelines be fully embodied.

6） 塑料检查井内壁光滑流畅,摩阻系数小,污物不易滞留堵塞,雨污排放效率是传统检查井的一倍、塑料检查井为圆形井筒受力条件好。

6) The inner wall of plastic inspection wells is smooth and smooth, and the friction coefficient is small. The sewage is not easy to be retained and blocked. The drainage efficiency of rainwater and sewage is twice as high as that of traditional inspection wells. The stress condition of plastic inspection wells is good for circular wellbore.

7） 所使用的塑料原料,可回收利用,节省宝贵的粘土资源,符合国家可持续发展的基本国策、塑料检查井综合成本低,比传统检查井更具市场竞争优势。

7) The plastic raw materials used can be recycled, and valuable clay resources can be saved. It conforms to the basic national policy of sustainable development of the country. The comprehensive cost of plastic inspection wells is low, and it has more market competition advantages than traditional inspection wells.
