Description
Technical Field
The utility model relates to the technical field of urban road surface rainwater collection and drainage and outside lane flat stones, in particular to a design structure of an urban road surface linear water collection technology.
Background
With the continuous growth of the scale of cities, the current city construction concept of China is 'promoting the high-quality development of cities, and building park cities to make the cities healthier, safer and more pleasant and become a space for the high-quality life of people'. Therefore, the improvement of the quality of the urban infrastructure is imperative, and the collection and the discharge of the drainage (rainwater) of the urban road still have some defects, so that the development requirements of high quality and high quality of the city are difficult to meet.
1. Rainwater collection on urban roads mainly adopts a punctiform water collection mode, namely rainwater openings are formed in two sides of the roads every 50m or so, and rainwater on the road surfaces flows into rainwater pipelines under the roads after being collected by the rainwater openings and is finally discharged into a receiving water body. The water collecting mode has the problems of large road surface runoff, low drainage speed, unsmooth discharge and the like, and no better solution is provided at present.
2. Under the condition of short-time heavy rainfall, the phenomenon of 'seeing the sea' on the road is frequent. The rainwater on the road surface directly flows into the rainwater port; the rainwater on the road surface changes into river along the longitudinal slope and the cross slope runoff of the road without a rainwater port, thereby influencing the traffic safety of the road and hindering the travel of surrounding residents.
3. The road structure layer is prolonged by the runoff rainwater soaking time, the road surface is easy to damage, the road structure layer is unevenly settled, the service life of the road structure layer is seriously influenced, and the landscape effect of the road surface is also influenced to a certain extent.
4. The distance between the rainwater inlets is set (the distance between the rainwater inlets is required in drainage standards)
) The limit, for the convenience of inlet for the rainwater mouth inserts, rainwater inspection shaft interval is littleer (about 50 m) usually, leads to on the road surface rainwater inspection shaft quantity to increase, very easily appears "rotten eye", and visual impression and driving comfort are all unsatisfactory.
5. For landscape roads such as parks, greenbelts, riverways and the like on two sides of the road, the drainage requirements of buildings and users are randomly marked, and the problem of water collection on the road surface is only solved. At the moment, drainage (rainwater) facilities (rainwater pipelines, rainwater openings and the like) are only built for meeting the requirement of pavement drainage, so that the engineering investment is increased, and the landscape effect is not facilitated.
In view of the above circumstances, it is a necessary way for the development and construction of cities to develop a new way for collecting water on the road surface.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a design structure of a linear water collecting technology for an urban road pavement, so as to solve the problems in the background technology.

3. The linear water collecting mode is continuous in water collecting, and a continuous drainage channel is arranged in the side ditch, so that the problem that the traditional rainwater inlet cannot be connected in series too much can be solved; meanwhile, the method is not limited to the rainwater inlet interval required in the design Specification for outdoor drainage (GB50014), the arrangement interval of the rainwater inspection wells can be properly increased, the number of the inspection wells on the road is reduced, the phenomenon of 'rotten eyes' on the road surface is effectively relieved, and the driving comfort and the good road surface impression are improved.
4. The linear water collecting mode can increase the circulating time of rainwater in the side ditch and has certain delay effect on rainwater runoff flood peaks.
6. When urban roads are only considered to collect and discharge road surface rainwater, if linear drainage side ditches are arranged on two sides of a motor vehicle lane, the laying length of rainwater pipelines under the roads can be reduced, and underground space is saved.
7. Because the condition of uneven settlement possibly exists in the later stage of the motor vehicle lane, accumulated water points are easy to form, if linear drainage side ditches are arranged, only the pavement surface layer needs to be filled to the original elevation, the pavement does not need to be excavated, and drainage facilities (a rainwater port and a drainage pipeline) do not need to be additionally arranged, and the treatment method is simple and easy to implement.
8. The linear drainage side ditches are connected into a whole, and can be used as an external mold without slope during construction of a road structure layer, so that the engineering quantity of the road structure layer is reduced (detailed in table 1), and the comprehensive engineering cost is reduced (detailed in table 2).
9. The inner cavity of the linear drainage side ditch is arranged in an egg shape, so that an overflowing water head is raised relative to a semi-circle shape, the overflowing capacity is enhanced, the water conservancy condition is excellent, and siltation is not easy to generate.
10. The water collecting gap at the top of the linear drainage side ditch is narrow (not more than 25mm), fallen leaves or other impurities are difficult to enter the side ditch through the gap, and the side ditch is difficult to block; meanwhile, the coherent gaps are positioned on the two sides of the road, so that the lines are beautiful and the landscape effect is good.
11. The linear drainage side ditch can select other suitable products according to actual requirements, adopts off-site prefabrication and on-site assembly, is convenient to transport and construct, and is beneficial to shortening the construction period.
