三格化粪池厕所施工关键一是保证建筑质量，防止渗漏；二是把好过粪管安装质量关。
The first is to ensure the construction quality and prevent leakage; The second is to ensure the quality of fecal pipe installation.
1、施工人员工具的准备：具体施工人员应事先准备好砖刀、大小灰板、大小灰披、卷尺、水平仪、刷子、浇水泥用的模板等。
1. Preparation of tools for construction personnel: specific construction personnel shall prepare brick knife, large and small ash board, large and small ash drape, tape, level instrument, brush, formwork for pouring cement in advance.
2、材料的准备：在施工之前，施工人员需按砖砌、水泥预制、现浇等不同类型的用料需要，通知建厕农户，备足砖、水泥、砂石、钢筋、便器、进粪管、过粪管等材料，方可进行施工。
2. Preparation of materials: before construction, the construction personnel should inform the toilet farmers to prepare enough bricks, cement, sand, reinforcement, toilet, fecal pipe, fecal pipe and other materials according to the needs of brick, cement prefabrication, cast-in-place and other different types of materials.
3、放样和挖坑：根据用户需要和具体情况，选好化粪池的位置、确定形状和池子的大小，按照实际推广容积和各池长度量好尺寸，撒上石灰线。放线时应留出砖砌或现浇余地，一般每条边放出5cm 。
3. Lofting and digging: according to the user's needs and specific conditions, select the location of the septic tank, determine the shape and size of the tank, measure the size according to the actual promotion volume and the length of each tank, and sprinkle the lime line. When setting out, the space for brickwork or cast-in-place should be reserved. Generally, 5cm should be set out on each side.
放线完了以后，要进行挖三格粪池坑，掏出坑内的泥土。土坑的深度为120cm。
After setting out, we should dig three dung pits and take out the soil in the pit. The depth of the pit is 120cm.
4、底板的处理：底层先铺5 cm碎石垫层，上浇8cm厚混凝土，混凝土标号为150号。
4. Treatment of the bottom plate: the bottom layer is paved with 5 cm gravel cushion, and poured with 8 cm thick concrete, the concrete grade is 150.
5、砖砌或浇铸化粪池：按化粪池的尺寸先砌好墙体，分三格，中间分隔两道墙体，由于第二池较窄，施工有一定困难，因此，砌到一定高度后，抹好扭王块模具 高铁遮板模具 阶梯护坡模具 拱形护坡模具 卵形槽模具 保定室内设计培训 保定平面设计培训水泥再继续砌墙。注意埋放好过粪管各一根。混凝土浇铸化粪池应按尺寸固定好模板，然后用150号混凝土浇灌，厚度为5 cm并用湿草帘复盖，2天左右待水泥凝固后方可拆除模板。
5. Brick or cast septic tank: according to the size of septic tank, build the wall first, divide it into three grids, and separate two walls in the middle. Because the second tank is narrow, it is difficult to construct. Therefore, after building to a certain height, plaster the cement, and then continue to build the wall. Pay attention to bury a fecal pipe. For concrete casting septic tank, the formwork shall be fixed according to the size, and then poured with 150 concrete with a thickness of 5 cm and covered with wet straw curtain. The formwork can be removed after about 2 days of cement solidification.
