Description
Technical field
The utility model relates to road surfaces to clear up field, specially a kind of highway bridge road surface drainage device.
Background technique
With the fast development of China's economy and carrying forward vigorously for Process of Urbanization Construction, the construction of highway in China science of bridge building is needed
Ask also increasing, in recent years, the construction speed of the roads such as town road, highway is continuously improved, but some construction technologies
Problem also occurs therewith, especially the drainage system of highway bridge；Highway bridge surface drainage is very important problem, when
When there is ponding on road surface, easily there is tyre slip phenomenon in passing vehicle, leads to traffic accident occur, however ordinary highway bridge face
When drainage system is there is raining heavily, drainage speed is slow or sundries blocks the drain, and road surface is caused to have the problem of ponding,
Ponding exclusion is mainly carried out using the structure for excavating rhone on highway bridge bridge floor at present, the structure of this rhone is set
It counts relatively simple, destroys the basic structure of highway, so that road life shortens, there is drainage speed in actual use
Slowly, it is easy to block, accumulates the defects of sundries is not easily cleaned in rhone, existing novel pavement drainage arrangement exists when in use
Certain drawbacks not only more cannot simply open water drainage cover board when removing contamination to drainage arrangement, but also be difficult to row
Rubbish during water inside sewage is collected processing, blocking drainage pipeline is prevented, further, it is difficult to the rubbish inside pipeline
Unified taking-up and processing are carried out, is wasted a lot of manpower and material resources, is increased processing cost, bring in the actual operation process
Certain influence, for this purpose, it is proposed that a kind of novel pavement drainage arrangement.
On avenue, drainage manhole cover plays an important role in the rainwater dredged on street.Summer in China,
Rainwater is more, rainfall is big, and the precipitation on street if not ruled out in time is easy to appear ponding, waterlogging, will cause sternly to the traffic in city
The influence of weight, existing drainage manhole cover has plenty of round-meshed circular metal part, is leaked down rainwater by circular hole, due to circular hole
Size it is limited, drainage efficiency is lower；Have plenty of and is formed by several reinforcement weldings, the drainage manhole cover of this structure, although can
The rubbish such as branch, leaf and polybag to realize the quick drain of rainwater, but on street, are easily accessible in sewer, make
At peculiar smell, it is total that drainage arrangement refers to that the facilities such as collection, conveying, the processing of water quality and the discharge of draining are combined into a certain way
Body, the general name of drainage channels and building at different levels to water logging control, prevention against water-logging and anti-salt, drainage arrangement are typically found at drainage channel
On, drainage channel is generally divided into the several levels such as hondo, Zhigou and bucket ditch, when drainage area is larger or landform is more complex, gutter
Road series can suitably increase, it also functions to water storage and backwater effect mainly to drain sometimes, with the continuous construction in city,
The effect of drainage arrangement also becomes more to come also greatly, and with the blocking of urban inner drainage, when surface gathered water is excessive, ponding is not
Conducive to discharge, which results in a series of problems such as the traffic paralysis of urban inner and people's trip inconvenience, therefore, draining dress
It sets as one of component most important in municipal sewerage system, has to carry out sufficient design in process of construction, how go
Build a better drainage system.
