Description
技术领域 technical field
本实用新型涉及一种塑料检查井踏步承载试验检测装置，属于产品性能检测与试验领域。 The utility model relates to a detection device for a step bearing test of a plastic inspection well, which belongs to the field of product performance detection and testing.
背景技术 Background technique
检查井，俗称“窖井”，是在地下管线位置上每隔一定距离修建的竖井，是城市道路地下基础设施之一，主要供检修管道、清除污泥及用以连接不同方向、不同高度管线使用的构筑物。大部分设在转弯处、管道交汇处、管径或坡度改变处、跌水处以及直线管段上。塑料检查井由于具有密封性好，可全天候施工，不受天气制约，可分体组合，能上下调节高度，排水性能优异，施工方便，重量轻，易于运输，施工周期短，综合造价低，维护费用少等优点，而逐步取代了传统的砖砌结构或钢筋混泥土结构的检查井。塑料检查井在使用时，为了检修人员上下方便，往往在井壁上焊接踏步，以供人上下使用，但为了保证上下人员的安全，必须对焊接踏步进行承载试验检测，而现对塑料检查井的检测大多采用传统的材料试验机测试平台来达到，占地面积大，加载不平稳，测力范围窄，检测效率低。踏步作为维修人员进出检查井的阶梯，它的承载强度达到标准尤为重要，因此必须设计一种塑料检查井踏步承载试验检测装置。 Inspection wells, commonly known as "cellar wells", are shafts built at intervals of underground pipelines. They are one of the underground infrastructures of urban roads. They are mainly used for maintenance of pipelines, removal of sludge, and connection of pipelines in different directions and heights. The structures used. Most of them are located at bends, pipe junctions, pipe diameter or slope changes, water drops, and straight pipe sections. Due to its good sealing performance, the plastic inspection well can be constructed around the clock without being restricted by the weather. It can be combined separately, and the height can be adjusted up and down. With the advantages of low cost and other advantages, it gradually replaced the inspection well of the traditional brick structure or reinforced concrete structure. When the plastic inspection well is in use, for the convenience of maintenance personnel, steps are often welded on the well wall for people to go up and down. Most of the testing is achieved by using the traditional material testing machine test platform, which occupies a large area, the loading is not stable, the force measurement range is narrow, and the testing efficiency is low. As the steps for maintenance personnel to enter and exit the inspection well, it is particularly important that its bearing strength meet the standard. Therefore, it is necessary to design a plastic inspection well step load test device.
