Description

Technical Field

[0001] The invention relates to the technical field of road drainage structures, and in particular to a road surface transverse gap type drainage ditch and a construction method thereof. Background Art

[0002] In the drainage design of road engineering, the surface water of the road surface is generally collected in the side ditch in the form of lateral drainage by setting the road crown cross slope, and then discharged from the road boundary through facilities such as rapids troughs and drainage ditches. When the road crown cross slope is small, the road surface is wide, and the instantaneous rainfall is large, the surface water of the road surface will be difficult to quickly discharge from the road surface, which will significantly increase the thickness of the road water film and seriously affect the anti-skid performance of the road surface, which is easy to cause vehicles to slip and stall, causing casualties and economic losses. However, in the curved part of the road, it is necessary to set the road surface superelevation to offset the centrifugal force that the vehicle bears during the curve driving process. It is inevitable that there will be gentle cross slope sections or zero slope sections. In addition, for one-way roads with more than three lanes or wide road surfaces at the nose of interchanges, due to actual conditions such as construction quality, road subsidence, and instantaneous heavy rain, some sections have poor drainage, which seriously affects the driving comfort and safety on rainy days.

The radii corresponding to the first arc segment 13 and the third arc segment 15 are both R1, and the radius corresponding to the second arc segment 14 is R2, where R1 is greater than R2. The specific dimensions of the first arc segment 13, the second arc segment 14 and the third arc segment 15 can be optimized and adjusted as needed.

[0039] In some embodiments, a first support structure 16 and a second support structure 17 are provided on the drain trough body 1. Both the first support structure 16 and the second support structure 17 are connected to the drain trough body 1. Both the first support structure 16 and the second support structure 17 extend along the length direction of the drain trough body 1. The first support structure 16 and the second support structure 17 are equal in length to the drain trough body 1. The first support structure 16 and the second support structure 17 are symmetrically arranged. The first support structure 16 is located on one side of the water inlet 3, and the second support structure 17 is located on the other side of the water inlet 3.

[0040] In some embodiments, the first support structure 16 and the second support structure 17 have the same structure. Both the first support structure 16 and the second support structure 17 are angle steels. Both the first support structure 16 and the second support structure 17 include a first support plate 18 and a second support plate 19. One end of the first support plate 18 is connected to one end of the second support plate 19, and the first support plate 18 extends in a direction perpendicular to the second support plate 19. The first support plate 18 is connected to the drain trough body 1 by welding. The second support plate 19 of the first support structure 16 is located at the end of the first support plate 18 of the first support structure 16 close to the second support structure 17. The second support plate 19 of the second support structure 17 is located at the end of the first support plate 18 of the second support structure 17 close to the first support structure 16. After the concrete 20 is filled in the filling cavity 2, the first support structure 16 and the second support structure 17 are welded. The second support plate 19 of the first support structure 16 is flush with the first opening plate 9, and the second support plate 19 of the second support structure 17 is flush with the second opening plate 10. The second support plates 19 of the first support structure 16 and the second support structure 17 can play a limiting role on the bonding layer and the wearing layer 24 during the construction of the road surface transverse gap type drain trough 100 in this embodiment, preventing the bonding layer and the wearing layer 24 from loosening and falling off to block the water inlet 3.

[0041] In some embodiments, there are at least two drain trough bodies 1. The drain trough bodies 1 are arranged in sequence along the width direction of the road. The ends of the drain trough bodies 1 are arranged in a dislocation manner with the lane wheel track belt. The position of the lane wheel track belt is preferably located in the middle of the drain trough body 1, that is, in the middle of the length direction of the drain trough body 1, to avoid uneven settlement of the roadbed at the bottom of the road surface transverse gap type drain trough 100 caused by the long-term eccentric load of the vehicle, thereby affecting the flatness of the road surface. The length of the drain trough body 1 is 1 m to 3 m to avoid cracking caused by the shrinkage and expansion deformation of the mass concrete 20.

[0042] The present embodiment adopts a slit-type water inlet 3 with a width of 2 cm to 3 cm, which can quickly collect water on the road surface without affecting driving comfort; the drainage trough body 1 adopts a steel structure, and the interior of the drainage trough body 1 is filled with concrete 20 to form a combined structure of the steel structure and the concrete 20, which greatly improves the mechanical properties of the road transverse slit drainage trough 100, such as compression resistance and bending resistance, and ensures that the road transverse slit drainage trough 100 can withstand the long-term action of vehicle loads within the design period without being damaged. In addition, the prefabricated road transverse slit drainage trough 100 can simplify the manufacturing process, and the external drainage trough body 1 can be directly used as a template for concrete 20 to improve production efficiency; the drainage channel plate 11 forms a drainage channel 4 protruding in the direction away from the water inlet 3, which to a certain extent alleviates the slit cantilever existing in the rectangular drainage channel. The problems of too long structure and relatively concentrated structural stress are solved, and the structural stress distribution of the transverse gap type drainage ditch 100 of the pavement is optimized, and a certain water-passing cross-sectional area is guaranteed, so that the surface water of the pavement can be fully collected; the top surface of the transverse gap type drainage ditch 100 of the pavement is paved with a wear layer 24, and the first supporting structure 16 and the second supporting structure 17 are welded on the top surface of the transverse gap type drainage ditch 100 of the pavement to provide lateral support for the wear layer 24 on the top surface, thereby achieving a smooth transition and a unified appearance between the section where the transverse gap type drainage ditch 100 of the pavement is located and the general section, and the added flexible wear layer 24 and the adhesive layer with waterproof effect can alleviate the infiltration of surface water and the decrease in flatness caused by the deformation of the pavement structure to a certain extent, thereby reducing the sense of frustration when the vehicle passes through the transverse drainage ditch quickly and improving driving comfort.

[0043] The transverse slit drainage groove 100 of the road surface of this embodiment can significantly improve the structural stress state under the action of traffic load, can adapt to the action of long-term traffic load, ensure that vehicles pass through the transverse slit drainage groove 100 of the road surface smoothly and quickly, and effectively guarantee driving comfort without obvious frustration. By setting a single row or multiple rows of transverse slit drainage grooves 100 of the road surface with a long drainage path or poor drainage such as wide road surface, gentle slope section, zero slope section, etc., the drainage path of the water on the road surface is effectively shortened, and the thickness of the water film on the road surface is reduced in rainy weather, thereby greatly improving the safety of high-speed driving on rainy roads, reducing the incidence of traffic accidents, and reducing casualties and economic losses.

[0044] Embodiment 2

[0045] like Figures 1 to 6 As shown, this embodiment also discloses a construction method of a road surface transverse gap type drainage groove 100 of embodiment 1, comprising:

[0046] Step 1: groove the pavement structure to form a placement groove 26, which is sequentially extended by a crushed stone layer 27, a water-stable layer 28 and an asphalt layer 29 of the pavement structure;

[0047] When grooving the pavement structure, there are two cases:

[0048] In the first case, for a newly built road, after the pavement structure is paved, groove according to the size of the transverse gap drainage trough 100 on the pavement. Reserve 4 cm to 5 cm in the width direction and 5 cm to 8 cm in the depth direction for filling cement mortar 25 for leveling. Groove the entire width range in the transverse direction of the road (i.e., the direction perpendicular to the driving direction), and remove the waste generated by grooving.

[0049] In the second case, for an existing road, after laying out and positioning the position of the transverse gap drainage trough 100 on the pavement, groove according to the size of the transverse gap drainage trough 100 on the pavement. Reserve 4 cm to 5 cm in the width direction and 5 cm to 8 cm in the depth direction for filling cement mortar 25 for leveling. Groove the entire width range in the transverse direction of the road (i.e., the direction perpendicular to the driving direction), and remove the waste generated by grooving.

[0050] Step 2: Form a cement mortar layer on the inner wall of the placement groove 26. Place the drainage trough body 1 one by one in the placement groove 26. Fill the cement mortar 25 between the cement mortar layer on the side wall of the placement groove 26 and the drainage trough body 1, and finally scrape the surface cement mortar 25 flat.

[0051] Step 3: Perform shot peening or sandblasting on the upper surfaces of the first top plate 5 and the second top plate 6 of the drainage trough body 1, spray hot modified asphalt to form a bonding layer, and lay a 4 cm to 5 cm thick hot mix modified asphalt mixture on the bonding layer to form a wearing course 24. The gradation and materials of the wearing course should be consistent with those of the general section. As an option, the hot mix modified asphalt mixture can use coarse aggregates such as basalt and diabase and SBS (styrene-butadiene-styrene, thermoplastic styrene-butadiene rubber) modified asphalt binder to improve the comprehensive road performance of the wearing course. The wearing course 24 is flush with the upper surface of the pavement structure and is compacted using a small compaction device. The traffic can be opened after the temperature of the wearing course 24 drops below 50°C. In this embodiment, by performing shot peening or sandblasting on the upper surfaces of the first top plate 5 and the second top plate 6, the surface roughness of the first top plate 5 and the second top plate 6 is improved, and the bonding effect between the bonding layer, the wearing course 24 and the drainage trough body is enhanced, avoiding diseases such as pushing and peeling, thereby improving the service life of the wearing course 24.

[0052] In the present invention, specific examples are used to elaborate on the principle and implementation manner of the present invention. The description of the above embodiments is only used to help understand the method and its core idea of the present invention; at the same time, for those of ordinary skill in the art, according to the idea of the present invention, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation to the present invention.
