The invention discloses a municipal road inspection well and a construction method thereof. The municipal road inspection well comprises a concrete shaft, a lime soil layer, an asphalt layer, a heavy cast iron well lid, a reinforced concrete bearing plate and a concrete layer. The reinforced concrete bearing plate is adopted, the influence of pavement load on deformation of the inspection well is changed, the load bearing area from the cover seat is enlarged, the reinforced concrete integral bearing plate disperses well cover concentrated stress, the roadbed is used for reducing the driving impact pressure of the shaft, the surrounding roadbed structure is used for sharing and bearing, and the shaft is not directly stressed independently; meanwhile, the problem that asphalt fragments fall off is solved, and the phenomena of local sinking and upheaval caused by uneven settlement of the periphery of the well circumference are overcome; by adopting the post-excavation construction method, the problems of bumping caused by the fact that the elevation of the inspection well is generally lower than the surrounding road surface at present, jerry work and material consumption and hollowness of the support in the process of lifting the cushion of the inspection well are solved, and the problem of traffic flow regulation is solved.

本发明公开了一种市政道路检查井及其施工方法，包括混凝土井筒、灰土层、沥青层、重型铸铁井盖、钢筋混凝土承载板、混凝土层。本发明采用钢筋混凝土承载板，改变路面荷载对窨井变形影响，扩大来自盖座的荷载承载面积，钢筋混凝土整体承载板分散井盖集中应力，利用路基降低井筒行车冲击压力，由周边路基结构来分担承载，不再单独由井筒直接受力，从而缓冲车辆冲击荷载，同时解决沥青碎块脱落问题，克服井周圈周边不均匀沉降导致局部下陷、拥包现象；采用后挖施工方法，解决了目前检查井标高普遍低于周边路面、导致跳车问题，解决了检查井起垫工序支撑偷工减料、空心问题，解决了交通调流问题。
