混凝土检查井模具用于适用于煤、热、水、电、气等市政地下构筑物的新型砌筑材料。如:排水、储水设施的各类检查井、雨水口、方沟、化粪池及小型构筑物、桥梁翼墙等。
对混凝土检查井模具进行处置的时机应选择在铺设完中沥青面层之后进行。按反开挖工艺开挖检查井模具基坑,以井口为圆心,开挖范围为井边外50深度至路床。应采用路面组合式检查井圆孔钻机或风镐人工破除,预留边缘部分采用人工凿除。混凝土检查井模具高程提前计算砌井墙砖皮数,高度应考虑钢筋砼圈梁井座及路面的尺寸关系,确保检查井盖与周边路面平整。
The concrete manhole mould is used as a new masonry material for municipal underground structures such as coal, heat, water, electricity and gas. Such as various inspection wells, rainwater inlets, square ditches, septic tanks and small structures of drainage and water storage facilitiesBridge, wing wall, etc.
The time for disposal of concrete manhole molds shall be after the laying of medium asphalt surface course. The mold foundation pit of the inspection well shall be excavated according to the reverse excavation process, with the wellhead as the center, and the excavation range is 50 deep outside the well to the road
Bed. The round hole drill or air pick of pavement combined inspection well shall be used for manual breaking, and the reserved edge shall be chiseled manually. The number of bricks on the well wall shall be calculated in advance for the mold elevation of the concrete inspection well, and the height shall consider the reinforced concrete ring beam well seat
And the size relationship of the pavement to ensure that the inspection well cover is flat with the surrounding pavement.
