The first is to ensure the construction quality and prevent leakage; The
second is to ensure the quality of fecal pipe installation.
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. 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. 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.
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. 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
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.
