Some specific embodiments according to the present invention, the first frame 12 are equipped with multiple overflowing along its circumferentially spaced arrangement
The mouth of a river 16, the size of gap 16 are not less than the bore size of rain grid 1, and turned-out fold of opening of the first frame 12 is turned over
Side 17, flange 17 ride upon water inlet convenient for the first frame 12 or are connected with other blowdown apparatus.
Optionally, as shown in figure 3, the height of two montants 13 in four montants 13 positioned at 12 the same end of the first frame is small
In the height of two montants 13 of the other end, the first frame 12 is horizontally disposed, and the second frame 14 tilts set relative to horizontal direction
It sets, 10 bottom surface of the first Hanging Basket uses inclined form, and in range to a certain degree, the accumulation of pollutants of retention is in bottom surface relatively low one
Side, to make the higher side of non-contaminant deposition retain itself conveyance capacity, after bottom, which is contaminated object, to be paved with, conveyance capacity
It reduces, rainwater is mainly flowed out by surrounding osculum 11, can still fall into the second interception area of the second Hanging Basket 20 formation.
According to one embodiment of present invention, as shown in Fig. 2, the second Hanging Basket 20 includes third frame 21, third frame 21
Be formed as rectangle frame and be connected with the first Hanging Basket 10, the projected area of third frame 21 in the horizontal plane exists more than the first Hanging Basket 10
Projected area on horizontal plane, filter screen 22 are located in rectangle frame, can be along stream when rainwater is flowed down along 10 side wall of the first Hanging Basket
Dynamic direction is fallen into the second Hanging Basket 20, realizes second interception.
According to one embodiment of present invention, the first frame 12, the second frame 14 and third frame 21 are respectively formed as not
Become rusty steel materials and parts, and filter plate 15 is respectively formed as metal material materials and parts with filter screen 22, and the Prefabricated combined septic tank 100 has enough as a result,
Strength and stability meets load bearing demand.
Preferably, filter plate 15 and the first frame 12, montant 13 and the second frame 14 can be to be weldingly connected, filter screen 22
May be to be weldingly connected with third frame 21, the knot that is weldingly connected is firm.
According to one embodiment of present invention, Prefabricated combined septic tank 100 further includes hinge 30, and one end of hinge 30 is formed as hook-shaped
To be connected with four apex angles of 14 bottom surface of the second frame, the other end of hinge 30 welds phase with four apex angles of third frame 21
Even, hinge 30 is stainless steel materials and parts, and hinge 30 has the characteristics that flexibility is high, is hardly damaged, good reliability and controllability are strong.
Preferably, Prefabricated combined septic tank 100 further includes handle 40, and handle 40 is located at opposite to two in the opening of the first frame 12
For lifting Prefabricated combined septic tank 100, handle 40 is stainless steel materials and parts and is weldingly connected with the first frame 12 for side.
The installation of Prefabricated combined septic tank 100 according to the ... of the embodiment of the present invention is detailed below and uses process.
By taking the transformation of present situation inlet for stom water as an example：As shown in figure 5, adaptable Prefabricated combined septic tank 100 is made according to inlet for stom water size, beat
Rain grid 1 is opened, after the first Hanging Basket 10 and the connection of the second Hanging Basket 20, is all put into inlet for stom water, at this time on the first Hanging Basket 10
Along being positioned on 1 bearing of rain grid, the suspension of Prefabricated combined septic tank 100 is completed, and rain grid 1 again upper cover is finally restored (newly-built
Engineering can omit the step of opening grate).
When rainfall, runoff rainwater enters inlet for stom water, falls into the first Hanging Basket 10, the retention area pair constituted by opening filter plate 15
Larger pollutant is retained, and rainwater is flowed out by the osculum 11 for retaining area bottom and surrounding, into the second Hanging Basket 20, by mistake
The retention area that strainer 22 is constituted carries out second interception area to rainwater, and particulate matter is trapped removal herein.
The pollutant for retaining area's bottom deposit, slides along inclined-plane to relatively low side, upper side retains itself conveyance capacity；When
After the contaminated object in bottom is paved with, conveyance capacity reduces, and rainwater is mainly flowed out by surrounding osculum 11, can still fall into second interception
Area.
When rainfall intensity and runoff rate are excessive, or the conveyance capacity in retention area is reduced to when being unable to meet demand, mistake
Amount rainwater is discharged by gap 16, and the gap between Prefabricated combined septic tank 100 and well body flows down, and is discharged into Storm Sewer Network.
To sum up, Prefabricated combined septic tank 100 according to the ... of the embodiment of the present invention, by being spaced setting the below the first Hanging Basket 10
Two Hanging Baskets 20, the Prefabricated combined septic tank 100 have thick, thin two-stage retention, and it is preferable to cut dirty effect, can reach prevention city black and odorous water,
Reduce the purpose of storm sewer silting；Excessive rainwater can be discharged by gap 16, and 16 conveyance capacity of gap is not less than rain
Eradicating water grate 1 crosses ability of staying, and draining is safe；Features simple structure prevents from blocking, and reliability is high, installation, dismounting, cleaning and maintenance
It is more convenient, have compared with high practicability and operability；Suitable for the environment-friendly type inlet for stom water for creating region and built region
Environment-friendly type inlet for stom water transformation.
Blowdown apparatus according to the ... of the embodiment of the present invention includes the Prefabricated combined septic tank 100 according to above-described embodiment, due to according to this
The Prefabricated combined septic tank 100 of invention above-described embodiment has above-mentioned technique effect, therefore, blowdown apparatus according to the ... of the embodiment of the present invention
With corresponding technique effect, that is, there is thick, thin two-stage retention, section dirty effect is preferable, can reach prevention city black and odorous water, subtract
The purpose of waterpipe silting short of rain；Excessive rainwater can be discharged by gap 16, and 16 conveyance capacity of gap is not less than rainwater
Grate 1 crosses ability of staying, and draining is safe；Features simple structure prevents from blocking, and reliability is high, installation, dismounting, cleaning and safeguard compared with
