Description

Technical Field

[0001] The utility model belongs to the technical field of civil engineering slope construction, and in particular relates to a road embankment slope drainage system. Background Art

[0002] During the construction of earth embankment slopes in the rainy season, heavy rains can easily cause water accumulation on the embankment road surface, which will wash and erode the earth embankment slopes, seriously affecting the slope stability and overall appearance. In general, the method of setting up earth dikes on the top of the slope and multiple interception channels at the corresponding positions of the route is used to prevent and control rainwater accumulation on the embankment road surface. Since the dikes used in this method are mostly made of earth, there is no good connection between the interception channels and the soil. In heavy rains, the dikes are often washed away, the interception channels slide and dislocate, and the soil near the interception channels slide and collapse. The interception and drainage effects are poor, affecting the quality of the slopes. The slopes need to be repeatedly repaired, which is time-consuming and labor-intensive. This method cannot be widely promoted and used.

[0029] Example 1

[0030] The utility model provides a road embankment slope drainage system, comprising a water retaining unit 11 arranged on the top of the slope, a drainage unit 12 arranged on the slope body, and a drainage ditch 13 arranged at the bottom of the slope, wherein the drainage unit 12 is formed by a plurality of water diversion structures arranged on the slope body being connected to each other, and the water diversion structure comprises a bottom plate 21, two water retaining plates 22 arranged on both sides of the bottom plate 21, a connecting groove 23 arranged on the end of the bottom plate 21 different from the water retaining plate 22, and a connecting plate 24 whose two ends are respectively connected to the connecting grooves 23 on two adjacent water diversion structures.

[0031] In this embodiment, in order to improve the sealing effect, a waterproof layer is provided on the lower surface of the connecting plate 24. The waterproof layer can be made of waterproof cloth, or it can be made by painting waterproof material on the lower surface of the connecting plate 23. Whether it is waterproof cloth or waterproof material, it is a technology well known to those skilled in the art, so it will not be described in detail.

[0032] It can be understood that the specific structure of the water retaining unit 11 and the drainage ditch 13 is a structure well known to those skilled in the art, and the specific functions are: the water retaining unit 11 is mainly used to block and collect precipitation on the top of the slope, and the water retaining unit 11 is connected to the drainage unit 12 to discharge the collected water into the drainage ditch 13 through the drainage unit 12.

[0033] Therefore, the structural setting of the drainage unit 12 is the focus of this embodiment, which is mainly used to solve the problem of water leakage at the joint when the drainage unit 12 is spliced ​​in the prior art. In this embodiment, the bottom plate 21 and the two water retaining plates 22 are integrally formed, and the U-shaped structure formed is used as the main structure of water delivery. The connecting groove 23 is opened at the front end of the U-shaped structure, and the opening of the connecting groove 23 forms a step surface on the bottom plate 21, and the lower part is just used to install the connecting plate 24, and after the connecting plate 24 is installed in the connecting groove 23, the surface of the connecting plate 24 is flush with the surface of the floor 21, thereby forming a completed plane for water delivery.

[0034] In this embodiment, since the two ends of the connecting plate 24 are respectively installed on two adjacent bottom plates 21, the joint between the two water diversion structures disappears, thereby avoiding the problem of water leakage. More preferably, after the two ends of the connecting plate 24 are respectively embedded in the two connecting grooves 23, the gap between the two bottom plates 21 is adjusted so that the sides of the two bottom plates 21 also abut against each other, thereby ensuring the tightness of the structure and reducing the probability of water leakage.

[0035] In this embodiment, the connection groove 23 is provided with a positioning hole 231, and the connection plate 24 is provided with a positioning column 241 adapted to the positioning hole 231. The purpose of such arrangement is to improve the installation accuracy of the connection plate 24 and improve the construction efficiency.

[0036] In this embodiment, the connecting plate 24 near the water retaining unit 11 or the drainage ditch 13 includes a first plate body 242 for connecting with the connecting groove 23, and a second plate body 243, one end of which is hinged with the first plate body 242 and the other end is connected with the water retaining unit 11 or the drainage ditch 13; the second plate body 243 is provided with a countersunk hole 244 and a connecting bolt 245 installed in the countersunk hole 244 and connected with the water retaining unit 11 or the drainage ditch 13. The purpose of such a setting is to take into account the problem that the unsmooth connection between the end of the water diversion structure and the water retaining unit 11 or the drainage ditch 13 will lead to a decrease in drainage efficiency, and by making the second plate body 243 cover the connection between the water diversion structure and the water retaining unit 11 or the drainage ditch 13, the smoothness of the connection is improved, and the water body is ensured to pass smoothly and quickly.

[0037] In some embodiments, the second plate 243 may be a flexible waterproof cloth, which is laid at the connection between the water diversion structure and the water retaining unit 11 and the drainage ditch 13 for transition. The flexible waterproof cloth is an existing material, so it will not be described in detail.

[0038] Compared with the prior art, this embodiment solves the problem of easy water leakage at the joints in the prior art mainly through the structural setting of the connecting groove and the connecting plate, and the structure has the advantages of simple installation and precise positioning.

[0039] Example 2

[0040] This embodiment further optimizes the structure based on the embodiment 1, as shown below:

[0041] The water diversion structure further includes a mounting plate 25 disposed at a side end of the water retaining plate 22 , a plurality of mounting holes 26 disposed on the mounting plate 25 , and fixing columns 27 passing through the mounting holes 26 and inserted into the soil layer of the slope.

[0042] The fixing column 27 includes a column 271 passing through the mounting hole 26, an external thread 272 arranged on the column 271, a limiting nut 273 threaded with the external thread 272 and located at the connection between the column 271 and the mounting hole 26, a tip 274 arranged on the end of the column 271, and an internal thread cap 275 arranged on the end of the column 271 away from the tip 274 and connected to the external thread 272.

[0043] It is worth mentioning that the setting direction of the mounting plate 25 is parallel to the bottom plate 21, and the lower surface height of the mounting plate 25 is higher than the lower surface of the bottom plate 21. The purpose of such setting is to provide an adjustment space on the mounting plate 25 for installing the limit nut 273. The limit nut 273 can determine the height of the mounting plate 25 on the column 271, so that the bottom plate 21 has a certain height adjustment range in the direction perpendicular to the surface of the slope body, which can not only maintain the parallelism between the bottom plate 21 and the slope body, but also accurately adjust the height difference between two adjacent water diversion structures, so that the installation connection line between the two is as parallel to the slope body surface as possible, further improving the tightness and smoothness of the connection between the water diversion structures, and ensuring the smooth and rapid discharge of water. The setting of the tip 274 is mainly used to facilitate the column 271 to enter the slope soil layer and improve the installation stability of the water diversion structure; the function of the internal threaded cap 275 is to cooperate with the limit nut 273 to accurately fix the position of the mounting plate 25 on the column 271, thereby ensuring the precise docking of the two water diversion structures, and the second function is to prevent the column 271 from being directly exposed to the external environment and rusting.

[0044] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
