| .检查井砌筑技术要点 Key points of inspection well masonry (1)在已安装完毕的排水管的检查井位置处，放出检查井中心位置线，按检查井尺寸摆出井壁砖墙位置。 (1) At the position of the inspection well of the drainage pipe that has been installed, set out the central position line of the inspection well, and set out the position of the brick wall of the shaft wall according to the size of the inspection well. (2)在检查井基础面上，先铺砂浆后再砌砖，一般采用一丁一顺或二丁一顺砌筑。每层砖上下皮竖灰缝应错开。随砌筑随检查尺寸。 (2) On the foundation surface of the inspection well, the mortar shall be paved first, and then the bricks shall be laid. Generally, the one-step masonry or two-step masonry shall be adopted. The vertical mortar joints on the upper and lower surfaces of each layer of brick shall be staggered. Check the dimension along with the masonry. (3)井内踏步，应随砌随安随座浆，其埋入深度不得小于设计规定。踏步安装后，在砌筑砂浆未达到规定强度前，不得踩踏。混凝土检查井井壁的踏步在预制或现浇时安装。 (3) The steps in the well shall be installed along with the masonry, and the embedded depth shall not be less than the design requirements. After the step is installed, it is not allowed to step on it before the masonry mortar reaches the specified strength. The steps of concrete inspection shaft wall shall be installed during prefabrication or cast-in-place. (4)排水检查井内的流槽，应在井壁砌到管顶时进行砌筑。水检查井流槽的高度与管顶齐平；雨水检查井流槽的高度为管径的1/2。当采用砖砌时，表面应用1：2水泥砂浆分层压实抹光，流槽应与上下游管道接顺。 (4) The launder in the drainage inspection well shall be built when the well wall is laid to the top of the pipe. The height of the flow channel of the water inspection well is flush with the top of the pipe; the height of the flow channel of the rainwater inspection well is 1 / 2 of the pipe diameter. When brick masonry is adopted, the surface shall be compacted and polished with 1:2 cement mortar layer by layer, and the chute shall be connected with upstream and downstream pipelines. |
