Abstract

The utility model discloses a catch basin silt filter unit, which comprises a catch basin silt sack. The body of the silt sack is made of the netty material. The shape of the sack opening is corresponding to the shape of the catch basin opening. Water flowing into a catch basin is filtered at first, and the solids such as silt, leaves, and the like, are collected in the sack, so as to lead the water that enters into the sewage not to contain the solids with bigger particles, which greatly decreases waterlogged probability of the pavement and guarantees smoothness of the sewage and the pavement. The filter unit of the utility model has the advantages of simple structure and convenient operation.

Description

A kind of inspection shaft silt filter

Technical field

The utility model relates to a kind of device that the water that enters inspection shaft is filtered of being used for.

Background technology

Inspection shaft in the urban road plays drainage, and the ponding on the road surface enters sewer by inspection shaft, and the road surface just can not flooded by ponding and keep unimpeded.But water advances entering the same of sewer by inspection shaft, also the solids on the road surfaces such as mud, sand, leaf is poured together sewer (especially when heavy rain or water pipe explosion, because discharge is big, the easier generation of this situation), thereby causes the obstruction of sewer.For avoiding freely influence road traffic because of following water, relevant department regularly (as the first quarter, half a year etc.) manually dredge between two inspection shafts with the overlength bamboo chip, not only operate inconvenient, labour intensity is high, and effect is undesirable again.Particularly China's number was economized and to be suddenly rained cats and dogs this year, and because of sewer has not freely caused disaster, even organic field suspends because of ponding, caused inconvenience to people's lives.

Summary of the invention

Thereby technical problem to be solved in the utility model be to propose a kind of simple in structure, easy to operate, can filter the water that enters inspection shaft and ensure the unobstructed inspection shaft silt filter of sewer.

For solving the problems of the technologies described above, a kind of inspection shaft silt of the utility model filter comprises inspection shaft silt bag, and the bag of described silt bag is made by Web materials, and its pocket shapes is corresponding with the inspection shaft opening shape.

Above-mentioned a kind of inspection shaft silt filter, the sack periphery of described silt bag are provided with a circle iron plate or mould sheet.

Above-mentioned a kind of inspection shaft silt filter, a described circle iron plate or mould sheet and can shrink.

Above-mentioned a kind of inspection shaft silt filter, described iron plate or mould sheet and be provided with draw ring or pulling eye.

Above-mentioned a kind of inspection shaft silt filter, it also comprises the inspection shaft fence, the cross-sectional openings of this inspection shaft fence is bigger than inspection shaft opening.

The utility model has been owing to adopted above-mentioned technical pattern, during use, the inspection shaft silt bag of filter is sheathed on the inspection shaft mouth, and it is fixing then its periphery to be pushed down the back with the inspection shaft lid.Like this, along with pouring solids such as silt in the inspection shaft, leaf together, water just can be collected in the bag behind the inspection shaft silt bag filtration, and the water that enters in the sewer does not just contain the bigger solids of particle substantially, thereby be difficult for causing sewer to stop up, thereby greatly reduce the probability of surface gathered water, ensured that the road surface is unimpeded.After accumulating the solids of certain capacity in the silt bag, the silt bag that can more renew, and old silt bag still can use after cleaning.It has simple in structure, easy to operate advantage.The sack periphery of silt bag is provided with a circle iron plate or moulds sheet is convenient to the fixing of silt bag, contractile iron plate or mould sheet and can make the silt bag be applicable to the inspection shaft of difformity, different sizes.Iron plate or mould sheet and be provided with draw ring or pulling eye can be when changing the silt bag, makes full use of environmental sanitation department existing equipment (as the crane that lifts by crane roadside bulky refuse case every day etc.), has the silt bag of solids to hang away with long-pending, the person's of lightening one's labor working strength.When transposing silt bag, deeply make on the road solids such as a large amount of silts, leaf directly pour sewer to make it blocked for preventing to cross with big flood because of heavy rain ponding, the inspection shaft fence can be placed the inspection shaft inlet peripheral, like this, just can play macrofiltration the water that enters in the inspection shaft.

Description of drawings

Fig. 1 is the structural representation of the inspection shaft silt bag of the utility model inspection shaft silt filter;

Fig. 2 is the structural representation of the inspection shaft fence of the utility model inspection shaft silt filter.

The specific embodiment

As shown in Figure 1, inspection shaft silt filter comprises inspection shaft silt bag 1, and the bag of silt bag 1 is made (can use materials such as woven cloth, plastic wire or stainless steel cloth) by netted braided material, and the shape of its sack is corresponding with the inspection shaft opening shape, as square, circle etc.The sack periphery is provided with a circle iron plate 2 (also can adopt and mould sheet), and the centre of a circle iron plate 2 is provided with fracture, makes iron plate 2 can take out tight or loosen.Iron plate 2 is provided with draw ring 3 (also can directly on iron plate 2 pulling eye be set).

As shown in Figure 2, inspection shaft silt filter also comprises inspection shaft fence 4, and it can adopt iron sheet, plastics etc. to make, and the density between its hurdle can design more greatly.The cross-sectional openings of inspection shaft fence 4 is bigger than inspection shaft opening.

Claims

1, a kind of inspection shaft silt filter is characterized in that, it comprises inspection shaft silt bag, and the bag of described silt bag is made by Web materials, and its pocket shapes is corresponding with the inspection shaft opening shape.

2, a kind of inspection shaft silt filter as claimed in claim 1 is characterized in that, the sack periphery of described silt bag is provided with a circle iron plate or moulds sheet.

3, a kind of inspection shaft silt filter as claimed in claim 2 is characterized in that, a described circle iron plate or the centre of moulding sheet are provided with fracture.

4, as claim 2 or 3 described a kind of inspection shaft silt filters, it is characterized in that described iron plate or mould sheet and be provided with draw ring or pulling eye.

5, as claim 1,2 or 3 described a kind of inspection shaft silt filters, it is characterized in that it also comprises the inspection shaft fence, the mode cross section aperture efficiency inspection shaft opening of this inspection shaft fence is big.
