Background technology
Bituminous paving because its road-ability is good, noise is little, construction convenient and swift with maintenance and become highway in China and
The primary structure form of urban road, but due to when bituminous pavement design horizontal wall inscription incorrect or asphalt pavement construction matter is set
Measuring the reasons such as poor, often there is the phenomenon such as impeded drainage, surface gathered water in bituminous paving, thus causes vehicle to sail hydrops section into
Shi Rongyi produces water drift phenomenon, and the coefficient of friction on road surface strongly reduces, and car braking distance is corresponding to be increased, and easily causes traffic thing
Therefore, cause serious threat to the traffic safety of vehicular traffic.
China's bituminous paving hydrops problem majority of case is at present, and bituminous paving failed to pay attention to road row in the design phase
Water designs, and causes horizontal wall inscription design unreasonable or be not provided with effective pumping equipment getting rid of landing rainwater on the way, Colophonium
Road surface just finds that the part way of road exists the problem such as impeded drainage, surface gathered water after being open to the traffic, if adjusting the most again
The horizontal wall inscription gradient or build the facilities such as drain pipe, gully, porous pavement maintenance project cost can be significantly increased and also construct change
Need during making to suspend traffic for a long time, make troubles to people's trip.

As preferably, when the outlet that this utility model is used is multiple, the spacing of adjacent two outlets is 5-
10m。
The beneficial effects of the utility model are:
This utility model provides a kind of maintenance of surface structure improving bituminous paving drainability, by bituminous paving
The transverse groove of upper surface and connecting with transverse groove is placed in the cannelure of bituminous paving sidepiece can effectively increase the cross-section of river
Area, effectively help the rainwater dropped on road surface quickly to discharge road scope；Bituminous paving with cutting can be effective
Improve surface layer coefficient of friction, and rainwater catchment can be kept the road surface relatively dry with vehicle tyre contact portion in groove,
Eliminate the hydroplaning between tire and bituminous paving, reduce the generation of vehicle water drift phenomenon；Road surface through cutting process after, road table
Become uneven, relative airtight cave between tire with road surface, cannot be formed, when vehicle crosses the road surface with cutting without
Method produces very fast compression and the release of air, and then traveling noise is weakened；Pavement Improvement process is easy, quick, can
Effectively save maintenance fund, shortens curing time, has significant economic and social benefit.

Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearer, real with concrete below in conjunction with the accompanying drawings
Executing example, be further elucidated with this utility model, the present embodiment is implemented under premised on technical solutions of the utility model, Ying Li
Solve these embodiments be merely to illustrate this utility model rather than limit scope of the present utility model.
If existing bituminous paving the design inadequate or horizontal Longitudinal Slope Design of the horizontal wall inscription gradient is improper, running into the sky that rainfall is bigger
Air-capacitor Yi Lubiao forms hydrops or the radial direction current along direction of traffic, has a strong impact on vehicular traffic safety.
This utility model is based on Problems Existing, it is considered to uses the method for road surface cutting to promote the drainage efficiency on road surface, increases
The moisture holding capacity of road, it is to avoid surface gathered water, improves the safety of bituminous paving rainy day driving.
As it is shown in figure 1, a kind of maintenance of surface structure improving bituminous paving drainability, including protobitumen road surface 1, laterally
Groove 2, cannelure 3, outlet 4.Transverse groove 2 is connected with cannelure 3, and cannelure 3 is connected with outlet 4, can make landing
Rainwater on road surface imports in transverse groove 2, then sequentially pass through transverse groove 2, cannelure 3, outlet 4 drain into runway road surface scope
Outside.
Transverse groove 2 can be perpendicular to direction of traffic or be 45 ° of angles with direction of traffic, and in the present embodiment, transverse groove direction takes
It is perpendicular to direction of traffic.Cannelure is parallel to direction of traffic, is arranged at the trackside of the relatively low side of road elevation.
Seeing Fig. 2, in the present embodiment, transverse groove 2 cross sectional shape takes rectangle, transverse groove groove width 8-9mm, takes in the present embodiment
8mm；Transverse groove groove depth 4-5mm, takes 5mm in the present embodiment；Transverse groove spacing 50-60mm, takes 55mm, cannelure in the present embodiment
Cross sectional shape takes trapezoidal, cannelure top width 100-120mm, takes 100mm in the present embodiment；Cannelure bottom width 60-80mm, this
Embodiment takes 60mm；Cannelure groove depth 20-30mm, takes 25mm in the present embodiment.
Cannelure arranges an outlet 4 every 5-10m, and in the present embodiment, outlet is spaced apart 5m.Outlet 4 with let out
The water discharger for road such as the mouth of a river, gutter is connected, outside the rainwater collected in cannelure 3 can being drained into road surface scope.
This utility model is applicable to that horizontal wall inscription design in protobitumen road surface is improper or bituminous paving drainage system drainage efficiency is too low
And cause rainwater to flow out road watch speed and cross the situations such as slow and surface gathered water.This utility model additionally provides a kind of bituminous paving cutting
Remodeling method is as follows: road cleaning is clean, according to spacing, the fabric width of cutting of cutting, if special messenger is on road before (1) cutting transformation
The line of ink marker on bullet on panel, to control the track route of gaining machine.(2) enter as the gaining machine preferably employing 16 cutter heads of 7.5KW
Row cutting, adjacent panels keeps groove to link up when cutting, and machine operator must control machinery at any time, it is ensured that cutting suitable
Straight degree and quality.(3) in operation process, cutter head cooling water amount is bigger, workman specialize in gaining machine water.(4) cutting
Operation process can produce the serosity mixing foreign material in a large number, bring inconvenience therefore when operation to construction cleaning, permissible
The crown slope on track is utilized to make mud flow to side, road, the then mud on labor cleaning road surface and foreign material.For road
On road, the remaining foreign material got off, rinse well road surface with giant, prevent slip from depositing on road surface.For as far as possible
Shorten the activity duration, during construction operation, it should carve one section and clean one section.(5), after having constructed, vehicle can be put
OK.
Of the present utility model ultimate principle, principal character and advantage have more than been shown and described.The technical staff of the industry
It should be appreciated that above-described embodiment limits this utility model, all employing equivalents or the mode of equivalent transformation the most in any form
The technical scheme obtained, all falls within protection domain of the present utility model.
