Description
Technical field
A kind of straight waterfall formula drain well lid of the utility model, is related to a kind of inspection shaft drained by straight waterfall formula to earth's surface
Lid, belongs to municipal works field.In particular to a kind of to be entered by inspection well cover outer edge, and piping lane is dropped into along vertical direction
It is interior, and be exhausted in time by return-air slot, and then improve the inspection well cover of drainage efficiency.
Background technique
Currently, needing a large amount of underground piping, such as sewer, gas piping, optical cable etc., therefore in urban construction
Piping lane can be built below city, will be installed inspection well cover in piping lane and earth's surface communicating position for the laying of pipeline, for preventing
Pillar corridor, inspection well cover are mostly circle, and are matched with cover seat of manhole, and with Process of Urbanization Construction, more and more flow automatically Land cover, because
This draining is all completed by inspection well cover, existing inspection well cover draining when, mainly by the drainage hole on inspection well cover into
Row draining, since top drainage amount is big, drainage hole limited amount, it may appear that impeded drainage, cannot along inspection well cover edge into
Row draining, and gas cannot be discharged in time in draining in piping lane, so that there are air pressures in piping lane, formed and contradicted to draining, drop
Low drainage efficiency.
Summary of the invention
In order to improve above situation, a kind of straight waterfall formula drain well lid of the utility model provides a kind of by outside inspection well cover
Edge enters, and drops into piping lane along vertical direction, and is exhausted in time by return-air slot, and then improves drainage efficiency
Inspection well cover.Structure is simple, convenient and practical.
A kind of straight waterfall formula drain well lid of the utility model is achieved in that a kind of straight waterfall formula draining basement of the utility model
Well lid is by inspection well cover, cover seat of manhole, edge rest platform, guiding supporting plate, connecting tube, bottom rest platform, confined planes, cover seat of manhole
Plate and return-air slot composition, connecting tube is placed in cover seat of manhole bottom, and is connected with cover seat of manhole, and multiple guiding supporting plates are respectively placed in company
In adapter tube, and the upward bending in one end extends to and is connected with cover seat of manhole inner wall, and the guiding supporting plate upper surface is equipped with bottom branch
Platform is held in the palm, the bottom rest platform is placed in cover seat of manhole, and it is flat that guiding supporting plate one end outwardly convex forms edge rest
Platform, and convex slope forms confined planes, is angularly distributed between multiple guiding supporting plates, inspection shaft is placed in cover seat of manhole,
The inspection well cover bottom and edge rest platform fit, be equipped between cover seat of manhole inner wall on the outside of the inspection well cover one section away from
From well lid seat board is placed in inspection well cover bottom, and cover seat of manhole board bottom portion and bottom rest platform fit, on the outside of the well lid seat board
It fits with confined planes, multiple return-air slots is provided on the inspection well cover, the import of the return-air slot is small, outlet is big.
" upper surface " that above-mentioned " upper surface " mentioned and will hereafter refer to is subject on attached drawing 1.
In use, connecting tube is placed in piping lane, and and piping lane on the pedestal for first reserving cover seat of manhole installation on the ground
It is connected, forms water stream channel between two adjacent guiding supporting plates, and then is formed between inspection well cover and cover seat of manhole multiple
Independent water stream channel, when being drained, water flow enters in the gap on the outside of inspection well cover between cover seat of manhole inner wall, flows into multiple water
It in circulation road, directly flows down into connecting tube then along guiding supporting plate, is drained subsequently into straight waterfall formula in piping lane, is formed,
Displacement is larger, drains more unobstructed, and as water flow is constantly injected, original gas is impacted in piping lane, and space by
It to compression, is displaced outwardly, is discharged eventually by return-air slot, and then guarantee the stability of air pressure in piping lane, prevent exhaust not in time
Draining is caused to hinder, drainage efficiency is improved, achievees the purpose that drain earth's surface by straight waterfall formula.
Beneficial effect.
One, structure is simple, convenient and practical.
Two, cheap, it is easy to spread.
Three, the efficiency to top drainage can be effectively improved.
Detailed description of the invention
Fig. 1 is a kind of stereo-resolution figure of straight waterfall formula drain well lid of the utility model.
In attached drawing
Wherein part are as follows: inspection well cover (1), cover seat of manhole (2), edge rest platform (3) are oriented to supporting plate (4), connecting tube
(5), bottom rest platform (6), confined planes (7), well lid seat board (8), return-air slot (9).
Specific embodiment:
A kind of straight waterfall formula drain well lid (1) of the utility model be achieved in that by inspection well cover (1), cover seat of manhole (2),
Edge rest platform (3), guiding supporting plate (4), connecting tube (5), bottom rest platform (6), confined planes (7), cover seat of manhole (2) plate
It is formed with return-air slot (9), connecting tube (5) is placed in cover seat of manhole (2) bottom, and is connected with cover seat of manhole (2), multiple guiding supporting plates
(4) it is respectively placed in connecting tube (5), and the upward bending in one end extends to and is connected with cover seat of manhole (2) inner wall, the guiding support
Plate (4) upper surface is equipped with bottom rest platform (6), and the bottom rest platform (6) is placed in cover seat of manhole (2), and the guiding is held
Supporting plate (4) one end outwardly convex forms edge rest platform (3), and convex slope forms confined planes (7), and multiple guiding are held
Supporting plate is angularly distributed between (4), and inspection well cover (1) is placed in cover seat of manhole (2), and inspection well cover (1) bottom and edge rest are flat
Platform (3) fits, and is equipped with a distance between cover seat of manhole (2) inner wall on the outside of the inspection well cover (1), cover seat of manhole (2) plate is placed in
