如何克服井盖“颠、破、响”三大顽疾?

来源:http://www.kpp647.com添加时间:2019-04-22 17:01:23

山东球墨铸铁井盖厂家发现,因井周破损井盖招致的伤人伤车事故屡见不鲜,小小井盖,已成为很多城市道路养管单位挥之不去的“心头痛”——井盖沉降、井周破损,而成为“隐形炸弹”、“吃人圈套”。井盖常见问题有哪些?

Shandong Ductile Iron Manhole Cover Manufacturer found that the accidents of injuring people and injuring vehicles caused by damaged manhole cover are common. Small manhole cover has become a headache for many urban road maintenance units, such as settlement of manhole cover and damage around manhole, and has become "invisible bomb" and "cannibalism trap". What are the common problems of well cover?

传统井盖受力集中在砖砌井墙,受碾压后易形成根底损坏、井盖下陷、井周破损。

The traditional well cover stresses are concentrated on the brick wall, which is easy to cause root damage, well cover subsidence and peri-well damage after being rolled and compacted.

问题缘由剖析

An Analysis of the Causes of the Problem

1。在车辆荷载作用下,由于构造刚度不同,检查井与四周路面变形不谐和,由此产生应力突变或应力集中,重复作用后便招致路面开裂;

1。 Under the action of vehicle load, because of the different structural stiffness, the deformation of inspection wells is not harmonious with the surrounding pavement, resulting in sudden stress change or stress concentration, and the repeated action will cause pavement cracking。

2.检查井在施工过程中未依照标准规范停止对称夯实,检查井井盖、井座不稳定,与路面高程或道路的纵、横坡度不吻合,形成行驶车辆跳车,会加大对井周路面的冲击;

2。 During the construction of inspection wells, symmetrical compaction is not stopped in accordance with the standard specifications, and the cap and seat of inspection wells are unstable, which does not coincide with the elevation of pavement or the longitudinal and transverse gradients of roads, thus causing vehicle jumping, which will increase the impact on the pavement around the wells。

3.检查井井盖和井盖座存在质量问题或者运用不当等都会惹起井盖呈现病害。

3. Inspecting the quality problems of well cap and well cap seat or improper application will cause the disease of well cap.

如何克制“颠、破、响”,井盖三大顽疾

How to restrain "bumping, breaking and ringing", the three major stubborn illnesses of well cover

  1. 严厉工程丈量。增强工程丈量放样、复核工作,防止井圈、井盖装置坐浆过厚;

1. Strict engineering measurement. Strengthen the work of measuring and lofting and checking in engineering to prevent the over-thick slurry setting of wellbore and cover device.

2.严厉施工流程。对施工人员停止装置工艺交底,严厉执行相关的施工技术请求。增强检查井井周夯实回填土强度认识,增强井座座浆密实度;严厉控制高程,保证检查井盖、井座与施工设计道路的高程或路面的纵、横坡度吻合;增强资料的管理和检查机制;现场人工拌和的配料必需严厉依照规范配合比拌和;

2. Strict construction process. For the construction personnel to stop the device process submission, strict implementation of the relevant construction technology requirements. Strengthen the understanding of the strength of the compacted backfill around the inspection well and enhance the compactness of the slurry of the well seat; strictly control the elevation to ensure that the elevation of the inspection well cover and the well seat coincides with the elevation of the construction design road or the longitudinal and transverse gradients of the road surface; strengthen the management and inspection mechanism of the data; and mix the ingredients manually in the field strictly according to the standard mixing ratio;

3.严厉验收规范。现场施工、监理要做好相关质量验收工作;

3. Strict acceptance criteria. On-site construction and supervision should do a good job of quality acceptance.

4.严厉井盖选型。检查井盖由于材质不同,其性能也各不相同,需求分离检查井盖的装置位置,选择适宜的井盖类型。在机动车道下的检查井盖,优先采用具备防响、防滑、防盗、防坠落和防位移功用的井盖。

4. Strict cap selection. Because of the different material and performance of the inspection covers, it is necessary to separate and inspect the location of the covers and select the appropriate type of covers. For inspecting well covers under motor lanes, priority should be given to those with functions of anti-noise, anti-skid, anti-theft, anti-falling and anti-displacement.
