塑料检查井的应用与施工
Application and construction of plastic inspection well
检查井是用于雨污水排放管道的附属构筑物,是便于定期检查和疏通管道,防止管道堵塞的必要设施。
The inspection well is an auxiliary structure for the drainage pipeline of rainwater and sewage. It is a necessary facility for regular inspection and dredging of pipelines and prevention of pipeline blockage.
传统砖砌检查井的施工方法是用砖块砌筑井体,然后将管道插入井体并用水泥砂浆填补井管接口处。该工艺落后,施工效率低,连接效果差会导致严重渗漏、泄漏,并违背了标准化原则。
The construction method of traditional brick inspection wells is to block the well body with bricks, then www.xingcheng365.com lfzhuangxiu.75ix.com qinhuangdao.89ix.comliuliwa.89ix.com uxingcao.75ix.cn huafenchi.75ix.cninsert the pipe into the well body and fill the interface of the well pipe with cement mortar. The technology is backward, the construction efficiency is low, and the poor connection results will cause serious leakage and leakage, and violates the standardization principle.
一、塑料检查井的适用范围
The scope of application of plastic inspection wells
1、建筑小区(居住区、公共建筑区、厂区等)范围内埋地塑料排水管道外径不大于800mm、埋设深度不大于6m、不下井操作的塑料排水检查井工程的设计、施工和维护保养。
1. The design, construction and maintenance of the plastic drainage pipe in the residential area (residential area, public building area, factory area and so on) is not more than 800mm, the buried depth is not more than 6m, and the plastic drainage inspection project is not under the operation of the well.
2、一般土质、软土土质、季节性冻土土质和湿陷性黄土土质条件下的塑料排水检查井施工。
2. Construction of plastic drainage well for general soil, soft soil, seasonal frozen soil and collapsible loess soil.
3、抗震设防裂度为9度及9度以下的地区。
3. The area with 9 degrees of seismic fortification and below 9 degrees.
4、一般车道的地面荷载按汽车总重15t(后轮压5t);消防车道的地面荷载按汽车总重30t(后轮压6t)设计。
4, the ground load of general lanes is 15t according to vehicle gross weight (rear wheel pressure 5T); the ground load of fire lane is designed according to vehicle gross weight 30t (rear wheel pressure 6T).
5、地下水位按地面下不高于1.0m设计。
5. The groundwater level is not more than 1.0m under the ground.
二、塑料检查井的组成
Two, the composition of the plastic inspection well
检查井由井座、井筒和井盖及其配件组成。
The inspection well is composed of a well seat, a wellbore and a well cover and its accessories.
1、井座材料一般以聚氯乙烯(PVC)、聚乙烯(PE)、聚丙烯(PP)等高分子树脂为主;
1. The material of well seat is mainly polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP) and other polymer resins.
2、井筒一般宜采用成品埋地塑料管材,其管材需符合下列要求:
2. Wellbore generally should be finished with buried plastic pipes, and the pipes should meet the following requirements:
(1)井筒管材的环刚度应大于等于4KN/m2;
(1) the ring stiffness of wellbore pipes should be greater than or equal to 4KN/m2.
(2)井筒材料应符合GB/T 10002.3、GB/T 18477.1、GB/T 19472.2和EN 1398.1(外径系列)标准的要求。
(2) wellbore materials should meet the requirements of GB/T 10002.3, GB/T 18477.1, GB/T 19472.2 and EN 1398.1 (outer diameter series) standards.
3、井盖材料主要以PVC塑料树脂、热塑性树脂(PE、PP、ABS等)和碳酸钙、粉煤灰、矿渣为主要原料,再添加一定的助剂。
3, the main materials are PVC plastic resin, thermoplastic resin (PE, PP, ABS, etc.) and calcium carbonate, fly ash and slag as the main raw materials, and then some additives are added.
三、塑料检查井与传统砖砌井的比较
Three, comparison between plastic inspection well and traditional brick masonry
1、制作工艺
1. Production process
塑料检查井:以高分子树脂为原料,工厂预制生产,一次注塑成型,质量稳定可控。
Plastic inspection well: using polymer resin as raw material, factory precast production, one injection molding, stable and controllable quality.
传统砖砌检查井:以粘土实心砖、水泥、黄砂为材料,现场手工制作。
Traditional brick inspection wells: clay solid bricks, cement, yellow sand as materials, on-site hand-made.
3、节能环保
3, energy saving and environmental protection
塑料检查井:节水、节地、节材、节能,同时废旧材料可循环利用,使用寿命长,至少50年;
Plastic inspection wells: water saving, land saving, material saving and energy saving. At the same time, waste materials can be recycled and their service life is long, at least 50 years.
传统砖砌检查井:砖砌检查井在制砖时耗费能源,耗费水资源,耗费良田,同时污染环境。
Traditional brick inspection wells: Brick inspection wells consume energy in building bricks, consume water resources, consume fertile fields, and pollute the environment.
