隐形井盖创新工艺改造 破解人行道管理难题

Stealth well cover innovation process transformation to solve sidewalk management problems

随着城市现代化水平的提高，市政道路作为城市基础设施和城市环境的载体,其建设标准也随之不断提升。近年来，我市的新建市政道路人行道大多采用大理石、烧结砖等铺装，同时人行道上的各类检查井也采用隐形井盖的形式，将检查井隐藏在人行道下面，以保证道路的整体美观性。

With the improvement of the level of urban modernization, the construction standards of municipal roads as urban infrastructure and urban environment have also been continuously improved. In recent years, most of the new municipal road pavements in our city are paved with marble and sintered bricks. At the same time, all kinds of check wells on the sidewalks also use the form of invisible well cover. The inspection wells are hidden under the sidewalk to ensure the overall beauty of the road.

但这种井盖自身重量太大，在后期管线单位的维护作业中，因井周边缝隙中塞满沙土开启困难，管线维修人员经常用铁锤、撬棍等敲击井盖甚至砸碎井盖内的人行道板方能开启井盖。这就导致人行道板缺失、损坏严重，不仅带来行人通行安全隐患，同时也影响道路形象，成为新的城市管理难题！

But the weight of this kind of shaft is too large. In the maintenance operation of the late pipeline unit, it is difficult to open the hole cover with iron hammer, crowbar and even smash the sidewalk board in the cover of the well. This leads to the lack of sidewalk panels and serious damage. It not only brings hidden dangers to pedestrians, but also affects the road image, becoming a new urban management problem.

为破解隐形井盖道板缺损难题，李沧区建管局市政部门创新改造工艺，在京口路果园路周边进行试点，采用在原隐形井盖模具上焊接镀锌花纹铁板取代水泥砂浆粘铺人行道板的维修方法，保障人行道设施完好，行人通行安全顺畅。这种改造工艺在青岛市属于首创！

In order to solve the problem of the defect of the stealth hole cover, the innovation and renovation process of the Municipal Administration Department of the Licang construction administration bureau was carried out in the vicinity of the Jingkou road Orchard Road. Unobstructed. This transformation process is the first one in Qingdao.

隐形井盖改造工艺

Transformation process of stealth shaft cover

先将病害井盖的水泥砂浆和铺装材料拆除，再对原井盖的方形模具进行打磨、开孔（可以将渗入的水分及时排除，减少对模具的锈蚀）、除锈、涂漆，后用 5 mm厚的镀锌花纹板焊接到原隐形井盖模具上，保证井盖顶面高程与道路高度一致。

First, the cement mortar and paving material of the damaged well cover are dismantled, and then the square mold of the original shaft cover is grinded and opened (which can be removed in time to reduce the corrosion of the mold), to remove rust and to paint, and then to be welded to the original stealth cover mold with 5 mm thick galvanized pattern plate to ensure the height of the top of the cover and the road. Highly consistent.

1、通过焊接镀锌花纹板替代水泥砂浆粘铺人行道铺装板材，降低了原隐形井盖的重量。经测量，原隐形井盖重量为124kg，改造后的隐形井盖为58kg，重量减轻了一半，提高了操作维修的灵活性。

1, by welding galvanized pattern plate instead of cement mortar to paste pavement pavements, reducing the weight of the original invisible manhole cover. After measurement, the weight of the original invisible manhole is 124kg, and the stealth manhole cover is 58kg, and the weight is reduced by half, which improves the flexibility of operation and maintenance.

2、通过充分利用原隐形井盖的模具，起到了节约材料、绿色环保的效果。

2, by making full use of the mould of the original invisible cover, it has the effect of saving materials and environmental protection.

3、通过使用镀锌花纹板材，保障了隐形井盖的强度，有效提高了防滑性和防锈、防腐性能。

3, through the use of galvanized plate, protect the strength of the invisible manhole cover, effectively improve the skid resistance, rust and corrosion resistance.

4、在盲道等特殊部位焊接5mm厚的不锈钢冲压盲条，与周边道路盲道顺接，保证盲道的使用功能的同时，在视觉上与周边环境相融合，道路环境更加优美和谐。

4, the blind track and other special parts of the blind track welding 5mm thick stainless steel stamping blind strip, and the surrounding road blind path to connect, ensure the use of the blind channel function, in the visual and surrounding environment, the road environment is more beautiful and harmonious.
