检查井砌筑技术要点
Key points of inspection shaft masonry Technology
(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) Set out the center line of the inspection well at the inspection well position of the installed drainage pipe, and set out the position of the wall brick 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 shaft, the mortar is laid first and then the brick is laid. Generally, one-step one-step or two-step-one-step masonry is adopted. The vertical mortar joint of upper and lower skin of each layer of brick shall be staggered. Check the size 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 built, installed and grouted at the same time, and the buried depth shall not be less than the design specification. After the step is installed, it is not allowed to step 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 chute in the drainage inspection well shall be built when the shaft wall is built to the top of the pipe. The height of the flow channel of the water inspection well is flush with the pipe top; The height of the chute of the rainwater inspection well is 1 / 2 of the pipe diameter. When brick masonry is adopted, the surface shall be compacted and polished by 1:2 cement mortar layer by layer, and the chute shall be connected with the upstream and downstream pipes.
3. 抹面、勾缝技术要求
3. Technical requirements for plastering and pointing
砌筑检查井、井室和雨水流水槽模具 u型槽模具 电缆槽模具 隔离墩钢模具 护坡砖模具 钢制闸门 螺杆式启闭机 卷扬式启闭机口的内壁应用原浆勾缝，有抹面要求时，内壁抹面应分层压实，外壁用砂浆搓缝应严密。其抹面、勾缝、座浆、抹三角灰等均采用1：2水泥砂浆，抹面、勾缝用水泥砂浆的砂子应过筛。
The inner walls of inspection well, chamber and rain inlet shall be pointed with original mortar. When there is a requirement for plastering, the inner wall plastering shall be compacted layer by layer, and the outer wall shall be tightly rubbed with mortar. The 1:2 cement mortar shall be used for plastering, pointing, setting and triangular plastering. The sand of cement mortar used for plastering and pointing shall be screened.
