1.产品运至工地时，安装前应对产品进行验收，是否是所需要的型号，检查有无破损。根据进污口、最终出水口以及施工图，测量场地放线，在确定能保证产品能放置的情况下进行挖槽。
When the product is shipped to the site, the product should be checked before installation, if it is needed, check for breakage. According to the fouling, the final outlet and the construction drawing, the measuring the line of the site is used to ensure that the product can be kept in place.
2.开挖确认地下是否有其他管线，有就要注意不要损坏。有无地下水、土质等情况。
Make sure that there are other lines in the ground, and be careful not to damage them. There is no groundwater, soil, etc.
3．根据化粪池的型号和土质情况，进行放坡（根据土质而定）。
According to the type and soil condition of the septic tank, the slope (according to the soil quality) is carried out.
4.挖槽前应准备好电源、水泵、干净水源、铁掀、合尺、测量仪器等，施工中必备的工具，以备出现特殊情况使用。
4. Chamfer should be ready before the power supply, water pumps, clean water, iron lift, tape, measuring instruments, such as the construction of the necessary tools, special condition for use.
5.所挖出的土，必须距槽四周5米以外，防止土的侧压造成塌方，另外也给吊装产品时留有工作场地。
The earth, which is dug up, must be five meters away from the groove, prevent the lateral pressure of the soil from causing a collapse, and also leave the work space for the suspension product.
6.遇有地下水时而且坑深度不够的情况下，必须用土袋等打围堰或者打桩，然后抽水，继续工作。挖好坑槽，测量标高是否达到要求深度。将探坑槽内的水抽净后铺设干性混凝土，使之找平，目的是使产品安装后沉降一致。同时在混凝土中预留四到八个角铁或者钢筋等，以便用绑带（不锈钢、塑料绳等不易生锈腐烂的物体）固定化粪池。
In case of ground water, and when the pit is not sufficiently deep, it must be used for cofferdam or piling, and then pumping and continuing to work. Dig the groove to measure whether the elevation reaches the required depth. Remove the water from the pit trough and then lay dry concrete and make it flat. The aim is to make the product settle after installation. At the same time reserved four to eight Angle iron or steel bar in concrete, etc., in order to use bind belt (stainless steel, plastic, etc. Is not easy to rust decay objects) fixed septic tanks.
7.无地下水时，对基础进行夯实、铺砂。根据示意图及要求进行基础处理。
When there is no ground water, the foundation is rammed and sanded. Base processing according to schematic and requirement.
