Abstract
The utility model provides a rainwater pipeline opening preventing a pedestrian from falling into, and relates to the field of urban drainage. The rainwater pipeline opening is used for increasing safety of a rainwater cover and reducing accidents. According to the technical scheme, the rainwater pipeline opening is characterized in that a cement platform is arranged on the inner wall of a rainwater pipeline and is 30-50cm far from a rainwater pipeline opening, a hole formed in the center of the cement platform is a drainage pipeline, a ground rainwater cover is fixed on the rainwater pipeline opening, ground rainwater drainage holes are formed in the ground rainwater cover, an inner rainwater cover is arranged on the cement platform arranged on the inner wall of the rainwater pipeline and is located below the ground rainwater cover, and inner rainwater cover drainage holes are formed in the inner rainwater cover. The rainwater pipeline opening has the advantages that after the ground rainwater cover is damaged, fragments of the damaged ground rainwater cover fall into the rainwater pipeline for filling, the distance between the inner rainwater cover and the ground is reduced, stepping-in difference is reduced, the inner rainwater cover is 30-50cm from a road surface, roller compaction by vehicles is effectively avoided, and completeness of the inner rainwater cover is guaranteed.
Description
Technical field
The present invention relates to urban sewerage and drainage field, particularly prevent that pedestrian from falling into the structure at a kind of rain pipe road junction of storm sewer.
Background technology
On the road in city, there is a lot of rainwater covers, rainwater cover adopts grid cement board or adopts grid iron plate, iron plate is easily stolen by people, cement board is easily ground bad by cart, when there is city ponding, people can't see rain pipe road junction, just likely fall into storm sewer, cause suffocating and die: evening on March 22nd, 2013 Changsha heavy rain, when 21 years old girl Yang Lijun pass by Changsha Tianxin District and are coated with house and rush helvolus road, unfortunately crashing into a uncovered sewer is flushed away, May 19, in the Yueyang according to approximately 160 kilometers of Changshas, local police finds young woman's corpse in Xiang River Xiangyin section.
Summary of the invention
For strengthening the safety measure of rainwater cover, reduce surprisingly, the present invention designs a kind of anti-rain pipe road junction of falling into.
The present invention realizes the technical scheme that goal of the invention adopts: a kind ofly anti-ly fall into rain pipe road junction, it is characterized in that: in the position apart from rain pipe road junction 30-50cm, at storm sewer inwall, have a cemented platform, the hole at cemented platform center is drainage pipe; Surface rain lid be fixed on rain pipe road junction above, surface rain is stamped surface rain lid drain hole, there is an inner rainwater cover below of surface rain lid in the cemented platform of storm sewer inwall, inner rainwater is stamped inner rainwater cover drain hole.
Cemented platform is annular plane, and width is 5-8cm.The diameter of surface rain lid drain hole is 1-2cm, and the Center Gap of surface rain lid drain hole is 5cm.The diameter of inner rainwater cover drain hole is 3-4cm, and the Center Gap of inner rainwater cover drain hole is 6-8cm, and inner rainwater cover adopts cast iron casting moulding, and thickness is 1-2cm.
The invention has the beneficial effects as follows: after earth's surface rainwater cover damages, its fragment drops above inner rainwater cover, reduce the distance on inner rainwater cover and earth's surface, reduce the drop treading in, reduce the probability of the pin of rivering bend, when pedestrian treads in rain pipe road junction, due to the support of inner rainwater cover, also be unlikely to fall into storm sewer, avoided potential safety hazard; Inner rainwater cover, apart from road surface 30-50cm, is effectively avoided rolling of automobile, has guaranteed the intact of inner rainwater cover; The present invention has increased the Safety Redundancy of rainwater cover, thereby strengthens the safety of rainwater cover.
Accompanying drawing explanation
Fig. 1 is a kind of anti-rain pipe road junction schematic diagram that falls into.Fig. 2 is the anti-two rainwater cover schematic diagrames of storm sewer that fall into.
Wherein, 1, rain pipe road junction, 2, storm sewer inwall, 3, cemented platform, 4, drainage pipe, 5, surface rain lid, 6, surface rain lid drain hole, 7, inner rainwater cover, 8, inner rainwater cover drain hole.
The specific embodiment
A kind of anti-rain pipe road junction of falling into, the places different from common rain pipe road junction 1 are, in the position apart from rain pipe road junction 30-50cm, at storm sewer inwall 2, there is a cemented platform 3, cemented platform 3 is identical with the shape of storm sewer, general storm sewer presents drum, therefore cemented platform 3 great majority adopt annular plane, its width is 5-8cm, the circular hole at cemented platform 3 centers is drainage pipe 4, surface rain lid 5 be fixed on rain pipe road junction 1 above, the external surface of surface rain lid 5 is the same with common rainwater cover, with earth's surface in same plane, surface rain lid 5 has surface rain lid drain hole 6, the diameter of surface rain lid drain hole 6 is 1-2cm, the Center Gap of surface rain lid drain hole 6 is 5cm, the below of surface rain lid 5, in the cemented platform 3 of storm sewer inwall 2, there is an inner rainwater cover 7, inner rainwater cover 7 has inner rainwater cover drain hole 8, the diameter of inner rainwater cover drain hole 8 is 3-4cm, the Center Gap of inner rainwater cover drain hole 8 is 6-8cm, inner rainwater cover 7 adopts cast iron casting moulding, thickness is 1-2cm.
