After the excrement decomposition precipitating for entering to precipitate chamber 15-1, the hyrate physical efficiency on upper layer enters clarification chamber 15-2 by water hole 16, thus
Enter discharge of pipes by outlet 28, prevents line clogging；In addition the excrement sludge to precipitate is decomposed by anaerobic fermentation, is made
Organic matter in excrement resolves into stable inorganic matter, and putrefactive primary sludge is converted into stable ripe sludge, changes excrement
Structure, reduce the moisture content of sludge, excrement drawn clearly to outward transport, landfill or be used as fertilizer, reduce environmental pollution.
In the present embodiment, the purpose of setting septic tank beam body 17 is in septic tank body 21: being to supply the first septic tank
The installation of cover board 22-1 and septic tank cover board connecting plate 23, on the one hand, be for the ease of bearing the first septic tank cover board and changing excrement
The weight of pond cover board connecting plate reduces septic tank cover board deflection deformation；It on the other hand is for the ease of by septic tank cover plate part
It is divided into multiple minor flaps and is attached installation, be easy to lift, reduces difficulty of construction.
In the present embodiment, the purpose that the first septic tank pit shaft 25-1 is arranged on the first septic tank cover board 22-1 is: first,
It is in order to increase the double-deck height for locking well lid 11, so that the double-deck well lid 11 that locks can partially basset, consequently facilitating to heavy
The deposit of shallow lake chamber 15-1 carries out extraction cleaning；Second, it is in order to backfill element soil on the first septic tank cover board 22-1 as change
Manure pit heat preservation, avoids septic tank from freezing, septic tank is caused to block.
In the present embodiment, the purpose that the second septic tank pit shaft 25-2 is arranged on the second septic tank cover board 22-2 is: first,
It is in order to increase the double-deck height for locking well lid 11, so that the double-deck well lid 11 that locks can partially basset, consequently facilitating to clear
The deposit of cavity clearing 15-2 carries out extraction cleaning；Second, it is in order to backfill element soil on the second septic tank cover board 22-2 as change
Manure pit heat preservation, avoids septic tank from freezing, septic tank is caused to block.
In the present embodiment, the purpose that long I-steel 3-2 is arranged is: being to increase two for the ease of the installation of pond body lifting lug 3-3
The spacing of the pond body lifting lug 3-3 of a length direction along septic tank bottom plate 8, consequently facilitating during ensuring lifting, septic tank
The steadily of centre of gravity of body 21；In addition, being the tension resistance shear behavior in order to increase septic tank bottom plate 8, septic tank bottom plate 8 is improved
Intensity.
In the present embodiment, the purpose that short I-steel 3-1 is arranged between two parallel long I-steel 3-2 is: being in order to even
I-steel 3-2 two long is met, so that I-steel 3-2 two long is connected as an entirety, so that it is guaranteed that four pond body lifting lug 3-3 rise
Uniform force when hanging；The tension resistance shear behavior for also increasing septic tank bottom plate 8 simultaneously, improves the intensity of septic tank bottom plate 8.
It is because precipitating decomposition is easy to produce biogas in septic tank, septic tank methane accumulation will increase pond in the present embodiment
Interior pressure can generate explosion, and snorkel 6 is arranged on well lid 11 so locking in bilayer, ventilates, so that it is guaranteed that septic tank
Interior pressure is in safe range.
In the present embodiment, shroud 5 is set outside snorkel 6, be the fallen leaves in order to avoid road surface, impurity or at any time etc. its
His pollutant enter snorkel 6 cause snorkel 6 block.
In the present embodiment, setting waterproof layer 14 with a thickness of 1mm~1.2mm, if the thickness of waterproof layer 14 is greater than 1.2mm
When, waterproof layer can crack, peeling, bond the problems such as insecure；If the thickness of waterproof layer 14 is less than 1mm, cannot effectively rise
To waterproof effect.
In the present embodiment, when it is implemented, the waterproof layer 14 is JS water-repellent paint, it is because anti-using other films
After water material is brushed, need to carry out the coating of mortar cover；And its coating for not needing mortar cover, reduce construction work
Sequence, and can effectively increase the volume in septic tank；In addition JS water-repellent paint does not pollute the environment, and ageing-resistant performance is strong, prevents
The water service life is long, can effectively adapt to buried septic tank, and its cohesive force is strong, JS water-repellent paint and septic tank medial surface
Adhesion strength improves its durability and stability up to 0.5MPa or more.
In the present embodiment, septic tank leads 9 medial surface of wall and the junction of 8 medial surface of septic tank bottom plate is provided with armpit angle 31
Purpose is: first, it is for the ease of leading wall 9 and the progress waterproof layer coating of 8 junction of septic tank bottom plate to septic tank；Second, be
In order to reduce the stress that septic tank leads wall 9 Yu 8 junction of septic tank bottom plate, septic tank is avoided to lead the company of wall 9 Yu septic tank bottom plate 8
It meets place and crack occurs.
In the present embodiment, the purpose that waterproof mortar course 10 is arranged at import 27 and outlet 28 is: being because being prevented first
The coating of water sand pulp layer 10 reduces the gap of import 27 and outlet 28, consequently facilitating import bellows 27-1 and outlet bellows
The installation of 28-1, so that the import bellows 27-1 of installation is located at the center of import 27, outlet bellows 28-1 is located at
The center of mouth 28；The purpose of leak stopping spirit packing course 2 is set, is because of import bellows 27-1 and outlet bellows 28-1 installation
Later, to clog import bellows 27-1 and export gap certain between bellows 28-1 and waterproof mortar course 10, thus really
Protect the sealed connection of import bellows 27-1 and import 27 and outlet bellows 28-1 and outlet 28.
In the present embodiment, when it is implemented, JS water-repellent paint can also be used in the leak stopping spirit packing course 2.
In the present embodiment, the concrete cushion 29 with a thickness of 100mm~120mm.
In the present embodiment, the purpose of the bottom setting concrete cushion 29 of septic tank body 21, first, it is to be change excrement
Pond provides a smooth mounting surface, it is ensured that septic tank lifts in place；Second, it is because if there is ground in septic tank installation region
It is lauched stretching or rainwater is entered in foundation pit, the bearing capacity of bottom of foundation ditch can be destroyed, septic tank is caused to tilt or settle；The
Three, it is to avoid septic tank bottom to generate ponding for water proof, draining, influence soil matrix condition.
In the present embodiment, setting concrete cushion 29 is with a thickness of the purpose of 100mm~120mm: if concrete mats
The thickness of layer 29 is greater than 120mm, on the one hand will increase construction cost, on the other hand can increase the height of septic tank body, cannot
Effectively ensure that the thickness of the above back fill course of septic tank cover board；If the thickness of concrete cushion 29 is less than 100mm, bearing capacity
It is small, isolation effectively cannot be supported to septic tank.
In the present embodiment, the spacing of two neighboring water hole 16 is 250mm~300mm, and the water hole 16 is rectangle mistake
Water hole.
In the present embodiment, the purpose that lower layer's steel mesh 1 and upper steel mesh 4 is arranged is: being for the ease of suspender 3 on the one hand
The installation of middle long I-steel 3-2 and short I-steel 3-1；On the other hand, it is strength and stability in order to enhance septic tank bottom plate.
In the present embodiment, because pouring to form septic tank bottom plate 8 and septic tank leads wall 9 first during practice of construction, so
9 top of wall is led in septic tank afterwards to pour to form side wall 12, therefore is set in the junction that side wall 12 leads wall 9 with septic tank
It is equipped with steel plate for sealing water 7, so that one end of steel plate for sealing water 7 protrudes into septic tank and leads wall 9, the other end of steel plate for sealing water 7 protrudes into all side walls
Body 12 avoids seeping water to realize that side wall 12 and septic tank lead the further waterproof of the junction of wall 9.
