Description
Technical field
The present invention relates to sewage, excrement and urine treatment technology field, and in particular to a kind of monolithic reinforced-concrete filth disposal
Pond and preparation method thereof.
Background technique
Filth disposal is to handle the sewage in life or in industry, and septic tank is to handle sewage or excrement
A kind of device, sewage is mixed with dirt under normal conditions, the sludgd deposition of heavy amount in lower vessel portion, lightweight
In upper vessel portion, the outlet by the way that one end is arranged in is discharged for sewage and the methane accumulation of generation.First of compartment plate
Lower hole excrement, dirt gear in the first interior, after anaerobic fermentation, the deposition of dirt of weight is in bottom of pond, and water is from the first Room
Flow to second Room.Continue to precipitate by second Room, water flows to third room from the hole on second compartment plate, and process is sunk several times
It forms sediment, the water from outlet outflow is substantially clear water, then drains into municipal pipeline and carries out disinfection processing.
Excrement, sewage treatment product currently on the market has glass toughening manure pit, prefabricated octagonal (rectangular) reinforced concrete
Native septic tank.
Glass fiber reinforced plastics septic pool volume is big, and the first warehouse accounts for whole half, light-weight, is readily transported.But this product is not
Acid and alkali-resistance, service life are short.It is used in residential quarters, after 20-30, aging is needed to change.Moreover, product price is more expensive, no
Energy pressure-bearing, can not install under lane.
Prefabricated octagonal (rectangular) reinforced concrete septic tank, acid and alkali-resistance, long service life can achieve project of vital and lasting importance
Standard can also be installed under cell road, and load-bearing presses every meter up to 30 tons or more.But such first warehouse of product is small, it is easily stifled
Plug, and because live lamination is installed, seam is more, welding, is easy displacement, is detached from, infiltration.Pond body is caused to settle after several years, it is dirty
Water, fecal pollution underground water pollute environment.

3. the first steel plate strip tailored by dome-shaped cutting is respectively welded in two ends and is welded with reinforcing rib, in the first steel plate
The first steel plate is welded on item.The thicker steel plate strip with a thickness of 80-100mm of first steel plate strip, preferred thickness 80mm.Certainly,
The thickness of first steel plate strip is also possible to 90mm or 100mm.Then, bottom plate is welded at 250 position of groove marked and is divided
Vertical plate is not welded in the two sides of bottom plate, to form groove 250.The first steel plate pot cover is welded in two ends again.First steel plate pot cover
That the semicircle lid formed is welded by multiple fan-shaped steel plates, lid is the arcwall face outwardly protruded, evagination one facing towards
On the outside of mold, to facilitate subsequent demoulding.
Upper punching block internal model 211 is made in 1-3 through the above steps.
4. the second steel plate strip of dome-shaped is tailored in cutting, as upper 212 moulding of punching block external mold.Similarly, the second steel plate strip
Thickness be also 80-100mm thicker steel plate strip, preferred thickness 80mm.Certainly, the thickness of the second steel plate strip is also possible to
90mm or 100mm.Casting gap is reserved between the first steel plate and the second steel plate strip.
5. putting the second steel plate strip, lateral I-steel and longitudinal steel plate strip and welding, 212 steelframe of punching block external mold in composition.
When putting, according to the shape-designing of upper punching block internal model 211 at dome-shaped.
6. smooth the second steel plate tailored by dome-shaped cutting of mating formation in side on upper 212 steelframe of punching block external mold by wind mould
And spot welding.Second steel plate is two pieces of curved plates, and two piece of second steel plate extends along mold axis, and two piece of second steel plate interval is set
It sets, so that the notch extended along mold axis is reserved at the top of upper punching block external mold 212, with the subsequent casting of aspect.
7. the two ends in upper 212 steelframe of punching block external mold weld the second steel plate pot cover.Equally, the second steel plate pot cover be also by
Multiple fan-shaped steel plates weld the semicircle lid to be formed, and lid is the arcwall face outwardly protruded, and the one of evagination is facing towards mold
Outside, to facilitate subsequent demoulding.
Upper punching block external mold 212 is made in 4-7 through the above steps.
(12) lower punching block is prepared, including prepares lower punching block internal model and lower punching block external mold:
1. it is framed to be combined into rectangular lower chassis with I-steel and channel steel welding, then divides venting line, marks 250 and of groove
The position of two ends.
2. two arc section channel steels are welded at the framed both ends of lower chassis and are connected the arc section channel steel at both ends with reinforcing bar,
It is arranged positioned at two ipsilateral arc section channel steel intervals, to reserve the space of setting upper frame frame mould；Then, in arc section channel steel
Rectangular upper frame frame mould is combined into I-steel and channel steel welding in the space that top reserves.
3. the third steel plate strip tailored by arc-shaped cutting is respectively welded in two ends and is welded with reinforcing rib, in third steel plate
Third steel plate is welded on item.Bottom plate is welded at the groove location marked and welds vertical plate in the two sides of bottom plate respectively, with shape
At groove.Third steel plate pot cover is welded in two ends.
Lower punching block internal model 221 is made by upper step 1-3.
4. the 4th steel plate strip of dome-shaped is tailored in cutting, as lower 222 moulding of punching block external mold.In third steel plate and the 4th steel
Casting gap is reserved between lath.
5. putting the 4th steel plate strip, lateral I-steel and longitudinal steel plate strip and welding, lower 222 steelframe of punching block external mold is constituted.
6. smooth the 4th steel plate tailored by arc-shaped cutting of mating formation in side on lower 222 steelframe of punching block external mold by wind mould
And spot welding.
7. the two ends in lower 222 steelframe of punching block external mold weld the 4th steel plate pot cover.
It should be noted that the punching block internal model 221 and when lower punching block external mold 222 under production, can refer to punching block internal model 221
With lower punching block external mold 222, in the application, third steel plate strip, third steel plate, third steel plate pot cover, the 4th steel plate strip, the 4th steel plate
And the 4th steel plate pot cover, model, structure and size etc. respectively in upper punching block 210 the first steel plate strip, the first steel plate,
First steel plate pot cover, the second steel plate strip, the second steel plate and the second steel plate pot cover, details are not described herein again.
Lower punching block external mold 222 is made in 4-7 through the above steps.
(13) it according to the big little makings compartment model of interiors of products, then, is welded at the top of upper punching block external mold 212 with steel plate
Manhole out.Specifically:
According to the big little makings compartment model of interiors of products, compartment model is by the channel steel brake forming with a thickness of 50mm.
Then, manhole is welded out with steel plate at the top of upper punching block external mold 212.The top of upper punching block external mold 212 is arranged in manhole
In notch.
(2) assembling reinforcement skeleton:
It is laid with steel mesh and screw-thread steel according to the shape of punching block, to form framework of steel reinforcement between external mold and internal model.Specifically:
(21) 3 first screw-thread steels are curved punching block arc and are through in triangle u stirrup in a groove and bound.Triangle
Stirrup is the screw-thread steel brake forming for being 8mm by diameter.Preferably, the diameter of the first screw-thread steel is 12mm.
(22) the second screw-thread steel that diameter is greater than the first screw-thread steel is discharged into rectangularity in punching block bottom, and by the first spiral shell
