Fabricated split prefabricated assembled inspection well and construction method thereof
According to the scheme, the construction method comprises the following construction steps that S00, a pipeline and a groove of the inspection well are excavated, tamping treatment is conducted on a foundation of the inspection well, then a cushion layer is laid, and pre-pressing treatment is conducted on the cushion layer through a pre-pressing device; s10, prefabricating an upper well chamber without holes, a lower well chamber with holes, a cover plate, a load reduction annular plate and a side wall truss; s20, the inspection well is installed; s30, vertical rods of the side wall truss are inserted through fixing rings until embedded plugs of the vertical rods are fixedly installed in embedded holes in the expanded bottom ends, and then a load reduction annular plate is welded and installed on the top of the side wall truss; and S40, slope protection and reinforcement are conducted on the side edge of the excavated pipeline, then foam concrete is used for backfilling the periphery of the inspection well, and construction of the inspection well is completed. The inspection well combines the advantages of a prefabricated concrete inspection well and a plastic inspection well, and is convenient and fast to construct, small in dead weight, large in rigidity, low in comprehensive manufacturing cost and low in maintenance cost.
本发明涉及装配式分体预制拼装检查井及其施工方法，该方案包括以下施工步骤：S00、开挖管线以及检查井的沟槽，对检查井地基进行夯实处理，然后铺设垫层并通过预压装置对该垫层做预压处理；S10、预制无开孔上部井室、开孔下部井室、盖板、减载环板及侧壁桁架；S20、检查井的安装；S30、将侧壁桁架的竖杆通过固定环进行插设，直到竖杆的嵌入插头安装固定在扩大底端的嵌入孔内，然后在侧壁桁架顶部焊接安装减载环板；S40、对开挖管线侧边进行护坡加固，然后利用泡沫混凝土对检查井周边进行回填，完成检查井的施工。本申请结合了预制混凝土检查井和塑料检查井的优点，施工方便快捷，自重小刚度大，综合造价低，维护费用少。
