Description
Technical field
The utility model belongs to water source transmission & distribution technology field, the specially efficient desilting pipe of nested type raw water water-supply-pipe.
Background technique
Raw water pipeline construction is the important link in a water supply project, and the safety of operation and water supply to water factory is related
The influence of keyness.In order to reduce entire water intake engineering energy consumption, in engineering design under the premise of meeting recent non-silting velocity, usually
Raw water aqueduct caliber can suitably be amplified, but this frequently can lead to water delivery pipeline system and becomes silted up in recent operating condition
Product even results in water factory's halt production and draws clearly, not only takes time and effort, can also threaten water supply security when serious.
The relevant technologies and the documents and materials for being directed to the product sand processing of raw water aqueduct at present are less, and in water treatment procedure
In widely used setting pot the advantages of it is main are as follows: rejection effect is preferable, the operation is stable, row sand setting it is more convenient, sediment outflow moisture content
It is low.But the shortcomings that setting pot, is main are as follows: construction investment is larger；Occupied area is larger；Construction Boosting pumping station need to be cooperated；Waterpower is stopped
Stay the time longer.Therefore it is not suitable for water source transmission & distribution.
Utility model content
In view of the above technical problems, the utility model provides a kind of efficient desilting pipe of nested type raw water water-supply-pipe, is suitable for
Water source transmission & distribution.
To reach this purpose, the utility model provides the following technical solutions:
The specific technical proposal is:
The efficient desilting pipe of nested type raw water water-supply-pipe, the sand-settling device including round tube shape, the both ends of sand-settling device respectively with original
The connection of water aqueduct, the lower section of the bottom of the sand-settling device is longitudinally disposed, and there are four sand discharge buckets, and each sand discharge bucket bottom is set
There is sludge pipe, sludge pipe is equipped with valve.The diameter of the sand-settling device is greater than the diameter of raw water aqueduct, raw water water-supply-pipe
The top in road and the top of sand-settling device are concordant, and raw water aqueduct bottom and sand-settling device are connected by transitional slope.The transition
Slope reinforcing bar is equipped in slope.
Further, the longitudinally disposed four vertical branch pipes in the sand-settling device bottom, the branch pipe wall are fixed with
Concrete, the interior cavity for forming taper of concrete is sand discharge bucket.
Protrusion is equipped between adjacent sand discharge bucket, protrusion is located in sand-settling device, and raised top edge is horizontal, is equipped in protrusion
Reinforcing rib.
It is additionally provided with maintenance population on the sand-settling device, is equipped with ladder in the maintenance population.
The beneficial effects of the utility model are:
1, it using nested type high-efficiency sand settling pipe, is directly not required to aqueduct origin or beginning drop-over with raw water pipeline auxiliary construction
Independent structures are set, to significantly reduce its requirement to construction land area；
2, by the way that continuous four sediment outflow buckets are arranged in pipe, make water delivery is synchronous with sand setting to carry out, do not interfering raw water tubes
In the case where water inlet, reach water removal in silt particle the effect of, to drastically reduce hydraulic detention time needed for sand setting.
Detailed description of the invention
Fig. 1 is the longitudinal profile structure schematic of the utility model；
Fig. 2 is the horizontal cross-section structure diagram of the utility model.
Specific embodiment
With reference to the accompanying drawing, specific embodiment of the utility model is described in further detail:
As shown in Figure 1 and Figure 2, the efficient desilting pipe of nested type raw water water-supply-pipe, the sand-settling device 1 including round tube shape, sand-settling device
1 both ends are connect with raw water aqueduct 11 respectively, and the lower section of the bottom of the sand-settling device 1 is longitudinally disposed, and there are four sand discharge buckets
2, each 2 bottom of sand discharge bucket is equipped with sludge pipe 3, and sludge pipe 3 is equipped with valve.
Specifically having a size of 7 meters of the length of sand-settling device 1, caliber is DN2220 × 20, and tubing is steel pipe, and bottom is arranged four
