Installation instructions
When the septic tank is buried to a depth of ≧. meters, the ground load is highway grade. If the load exceeds highway grade, structural protection measures need to be added to the road surface. The specific situation will be determined by on-site technicians.
. When the septic tank is buried at ﹤. meters, if vehicles need to pass, structural protection measures need to be added to the road surface. The specific situation will be determined by on-site technicians.
. Burial depth calculation (as shown in the figure) and pipeline connection instructions
The calculation formula is as follows (the distance between the top of the water inlet pipe and the top of the septic tank tank, and the distance between the top of the upper pipe of the water outlet pipe and the top of the septic tank tank ).
No groundwater++ +
With groundwater+++ +
When ordering, the purchaser needs to explain the pipe diameter to the manufacturer. Before the septic tank leaves the factory, the manufacturer is responsible for the tank body Take out the connecting pipe, and the connection from the tank to the water inlet and outlet inspection well shall be completed by the purchaser. The pipeline connection shall refer to the technical regulations of pipeline engineering.
.The exhaust pipe of the septic tank is made according to the national standard atlas.
. For inspection well practices, please refer to the relevant practices in drainage projects in the North China Standard "General Atlas for Construction and Installation of Construction Equipment".
.Septic tanks in parallel
When the septic tank volume exceeds, two single tanks can be connected in parallel. (The distance between the two tanks should not be less than 1. The other methods are the same as those for the single tank).
Grooving and backfilling
The geological conditions should be understood when excavating the foundation trench
When the local endurance is ≧ tons, if there is groundwater, well points or open drainage can be carried out according to the situation and then laid to ≧ level It is enough to lay the sand cushion after adding a sand and gravel cushion. When there is no groundwater, the bottom of the tank needs to be tamped. After the bottom of the tank is tamped, the sand cushion is laid to avoid being buried on a foundation with poor soil quality.
. The local endurance is ﹤ton-hour. The foundation needs to be added with ≧concrete cushion and then sand cushion can be laid.
The slope of the foundation trench can be determined according to the soil conditions, but a backfill working surface should be left around the septic tank.
After the septic tank is installed in place, the soil should be backfilled in time. When backfilling the soil, both sides of the bottom of the septic tank must be compacted, and the compaction coefficient should be above %. The backfilling of soil and filling of the septic tank with water should be carried out at the same time. The water filling level must be up to The upper outlet of the septic tank is located to prevent the septic tank from shifting. It is strictly forbidden to use construction waste as backfill, and sharp stones must be removed.
