[0071] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the present application.

[0072] As shown in Figure 1 and Figure 2 The present application provides a pavement anti-drainage construction method, which comprises:

[0073] Cement and broken stone mixture is laid on the top of the subbase layer to form the water blocking layer 1;

[0074] The positioning steel frame 4 is inserted and fixed on the water blocking layer 1 before the water blocking layer 1 is formed, and a plurality of drainage pipe fittings 5 are laid on the water blocking layer 1 at equal intervals through the positioning steel frame 4 after the water blocking layer 1 is formed, and asphalt broken stone is laid to form the drainage and permeation layer 2;

[0075] The asphalt concrete layers with different particle sizes are laid on the drainage and permeation layer 2 in sequence to form the pavement layer 3.

[0076] The drainage pipe fittings 5 on both sides of the pavement center line 6 form an inclined downward slope, and the drainage pipe fittings 5 are arranged in parallel, as shown in Figure 3 The drainage pipe fittings 5 are provided with a plurality of drainage holes 7 upward, and the drainage pipe fittings 5 at least have the top blocking pipe 51 and the bottom blocking pipe 52, which are arranged in sequence from top to bottom, as shown in Figure 4 The top blocking pipe 51 is connected with the impact pipe 53, and the top blocking pipe 51 and the impact pipe 53 form the intersection impact area 55 at the connection position, as shown in Figure 5 The bottom blocking pipe 52 is connected with the inclined pipe 54.

[0077] The side surface of the drainage and permeation layer 2 forms two drainage openings 8 along the height direction, and the end portions of the top blocking pipe 51 and the inclined pipe 54 extend to the drainage openings 8 at different positions upward and downward, respectively.

[0078] In the application, the aperture of the drainage hole 7 needs to be controlled according to the actual situation, and if the particle size of the material in the upper part of the pavement layer is small, the aperture of the drainage hole 7 also needs to be reduced.

[0079] The pavement layer can be laid by using the asphalt concrete with different particle sizes, and the particle size gradually decreases from bottom to top.

[0080] In addition, in the application, the water blocking layer 1 is laid on the subbase layer, and the drainage pipe fittings 5 are arranged on the drainage and permeation layer 2, and the blocking layers of the first layer and the second layer are formed in sequence from bottom to top to block the upward rising of the fine particle soil of the subbase, so that the underground water and the fine particle soil are blocked below the drainage and permeation layer 2, and the situation that the subbase fine particle soil blocks the pipeline due to the upward rising of the underground water is reduced.

[0081] The impact pipe 53, the top blocking pipe 51, the inclined pipe 54 and the bottom blocking pipe 52 are arranged in sequence from top to bottom to provide the drainage channels in layers, so that the water bodies in different depth layers of the subbase are drained, and the water bodies in different depths are drained at the vertical line position close to the center line 6. In order to save the position of the water body drainage, two drainage openings 8 are arranged to drain the water bodies of the plurality of drainage pipelines, and the two drainage openings 8 also have the corresponding effect of sharing one drainage opening 8, and the specific effect is as follows.

[0082] The top blocking pipe 51 and the impact pipe 53 share one drainage port 8, the impact pipe 53 is arranged on the top blocking pipe 51, and a meeting impact area 55 is formed at the connection of the top blocking pipe 51 and the impact pipe 53, the high-speed water flow in the impact pipe meets the low-speed water flow in the top blocking pipe 51 at the meeting impact area 55 and generates an impact, on the one hand, the double water flow impact collection makes the flow speed faster, reduces the freezing of the water body in the pipe, and on the other hand, the high-speed impact can knock the fine soil at the end of the pipe out of the pipe, avoiding pipe blockage.

[0083] The inclined pipe 54 and the bottom blocking pipe 52 share one drainage port 8, the bottom blocking pipe 52 is arranged below the inclined pipe 54, and there is a meeting point, on the one hand, the low-speed water flow in the bottom blocking pipe 52 slows down the speed of the fine soil of the roadbed flowing into the pipe to a certain extent, avoiding the accumulation of the fine soil of the roadbed at a position in the pipe and reducing the blockage of the fine soil of the roadbed in the pipe, and on the other hand, the high-speed water flow in the inclined pipe 54 impacts the groundwater or road surface water containing the fine soil of the roadbed at the meeting point, so that the water flows out of the pipe at high speed, avoiding the blockage of the fine soil of the roadbed in the pipe and improving the smoothness of the pipe.

[0084] To ensure the downward flow of the water body, the inclined pipe 54 and the impact pipe 53 form a downward slope outward from the center line 6 of the road surface as a starting point, and to ensure the impact and water flow speed effect, the application also makes the following design, as shown in Figure 4 and Figure 5 The inclination of the inclined pipe 54 is greater than that of the bottom blocking pipe 52, and the inclination of the impact pipe 53 is greater than that of the top blocking pipe 51.

[0085] The inclination of the inclined pipe 54 is greater than that of the bottom blocking pipe 52, and the bottom blocking pipe 52 not only blocks the fine soil of the roadbed, but also makes part of the fine soil of the roadbed flowing in the pipe flow at low speed, avoiding the blockage of the pipe by the accumulation of the fine soil flowing at high speed in a short time, the water body entering the bottom blocking pipe 52 first flows at low speed to avoid the blockage and accumulation of the fine soil in a short time, and then flows at high speed in the second half of the inclined pipe 54 to quickly drain the pipe and also to avoid surface blockage, the different inclination designs above achieve the segmented speed regulation effect of the water body flow.

[0086] The inclination of the impact pipe 53 is greater than that of the top blocking pipe 51, the water in the impact pipe 53 flows at a high speed, the water in the top blocking pipe 51 flows at a low speed compared with the water in the impact pipe 53, the high-speed water in the impact pipe 53 and the low-speed water in the top blocking pipe 51 meet at the intersection impact area 55 and generate an impact, the double water flow impact gathering makes the flow speed faster, reduces the freezing of the water in the pipe, and the high-speed impact can also drive the fine soil at the end of the pipe out of the pipe, avoids the pipe blockage, and the high-speed impact water can also impact the formed ice in the pipe and accelerate the melting of the ice.

[0087] In addition, in the present application, as shown in Figure 4 and Figure 5 The connection position of the inclined pipe 54 and the bottom blocking pipe 52 is at the end of the bottom blocking pipe 52, the connection position of the impact pipe 53 and the top blocking pipe 51 is away from the end of the bottom blocking pipe 52, and the connection positions of the inclined pipe 54 and the bottom blocking pipe 52 and the impact pipe 53 and the top blocking pipe 51 are on the same vertical line, which is also for the positioning of the steel frame 4.

[0088] In order to save the position of the pipe, the end positions of the top blocking pipe 51 and the inclined pipe 54 are adjacent to the end position of the drain outlet 8, the end positions of the top blocking pipe 51 and the inclined pipe 54 are close to each other, and the positioning steel frame 4 is used for fixing.

[0089] The pavement drainage construction method provided by the present application also comprises the following steps:

[0090] Based on the thickness and width of the roadbed bottom layer, the end positions of the inclined pipe 54, the top blocking pipe 51, the bottom blocking pipe 52 and the impact pipe 53 are calculated.

[0091] The distance from the end of the impact pipe 53 close to the position of the pavement center line 6 to the top of the drain permeable layer 2 is a, the distance from the end of the impact pipe 53 close to the position of the pavement center line 6 to the end of the top blocking pipe 51 close to the position of the pavement center line 6 is b, the distance from the end of the bottom blocking pipe 52 close to the position of the pavement center line 6 to the end of the inclined pipe 54 close to the position of the pavement center line 6 is c, and a:b:c = 0.5:1:1.

[0092] The above-mentioned proportional end position setting is to enable the inclined pipe 54, the top blocking pipe 51, the bottom blocking pipe 52 and the impact pipe 53 to be dispersed (wherein the top blocking pipe 51 and the inclined pipe 54 are arranged close to each other), and in the actual application process, the position of the drain outlet 8 is usually fixed, so the calculation of the position of the end of the pipe according to the proportion can usually obtain the fixed form of the pipe (which needs to ensure that the pipe is always inclined downward).

[0093] A proportion range value can also be set, for example, so that a occupies 20% to 35% of the drainage permeable layer 2, to adjust the position of the pipeline during installation.

[0094] The setting of the a:b:c=0.5:1:1 ratio is adjusted based on actual conditions, assuming that the road surface is narrow and the pipeline arrangement may not have enough space, at this time, a can be set to approach 0 (the end of the impact pipe 53 close to the road surface center line 6 position approaches the top of the drainage permeable layer 2), and the distance from the end of the bottom blocking pipe 51 to the water body group fault 1 is also set to approach 0.

[0095] In the present application, the top blocking pipe 51, the bottom blocking pipe 52, the impact pipe 53, and the inclined pipe 54 are installed and fixed by the positioning steel frame 4. The positioning steel frame 4 of the present application adopts the following preferred embodiments, as shown in Figure 11 and Figure 12 The positioning steel frame 4 includes a positioning U-shaped frame 41 arranged at the end of the top blocking pipe 51 and the inclined pipe 54 away from the drainage port 8, and a positioning shaft 42 arranged inside the positioning U-shaped frame 41. The positioning U-shaped frame 41 is inserted into the water body blocking layer 1 at the bottom, and the positioning shaft 42 is arranged in two. The outer width of the top blocking pipe 51 is greater than the outer width of the inclined pipe 54, and the inner width of the top blocking pipe 51 is consistent with the inner width of the inclined pipe 54. The two sides of the top blocking pipe 51 close to the bottom are each provided with a side slot 9, and the ends of the positioning shaft 42 are connected to the side slot 9 and the outer wall of the inclined pipe 54, respectively.

[0096] In the above embodiment, the outer width of the top blocking pipe 51 is greater than the outer width of the inclined pipe 54, and the two sides of the top blocking pipe 51 close to the bottom are each provided with a side slot 9. The top of the positioning U-shaped frame 41 corresponds to the installation of the side slot 9, and the side of the positioning U-shaped frame 41 corresponds to the installation of the outer side of the inclined pipe 54. The width of the positioning U-shaped frame 41 from the cross section is the same as the width of the pipeline, which reduces the horizontal occupation space of the positioning U-shaped frame 41 and enables the pipeline to be closely arranged, avoiding the water body from entering the horizontal gap between the pipelines.

[0097] In addition, the positioning shaft 42 is arranged to enable the positioning blocking pipe 51 and the inclined pipe 54 to be fixed on the positioning U-shaped frame 41.

[0098] In order to avoid interference between the above structure and the bottom blocking pipe 52, the end of the bottom blocking pipe 52 is arranged away from the road surface center line 6 and away from the positioning U-shaped frame 41.

[0099] In order to install and fix the top blocking pipe 51, the bottom blocking pipe 52, the impact pipe 53, and the inclined pipe 54, as shown in Figure 13 , Figure 14 , Figure 15 , Figure 16 ,Figure 17 As shown, the positioning steel frame 4 also includes a fixed frame 43 inserted into the water blocking layer 1, four positioning slots 44 set on the fixed frame 43, positioning cylinders 45 set in the positioning slots 44, and movable cylinders 46 movably set on the positioning cylinders 45. The positioning slots 44 are opposite each other in pairs. The end of the movable cylinder 46 penetrates through the side of the positioning cylinder 45 and extends into the interior of the positioning cylinder 45. The length of the movable cylinder 46 extending into the positioning cylinder 45 is less than the internal height of the top blocking pipe 51 and the inclined pipe 54. Figure 7 and Figure 8 As shown, the top blocking tube 51 and the inclined tube 54 are installed inside the positioning cylinder 45, and the impact tube 53 and the bottom blocking tube 52 are installed inside the movable cylinder 46. The end of the impact tube 53 extends into the top blocking tube 52, and the end of the bottom blocking tube 52 extends into the inclined tube 54.

[0100] In the above embodiment, the positioning groove 44 is adapted to the side of the top blocking pipe 51 and the tilting pipe 54 that have completed the tilt adjustment, that is, the tilt of the positioning groove 44 is the same as that of the corresponding pipe.

[0101] The length of the movable cylinder 46 extending into the positioning cylinder 45 is less than the internal height of the top blocking tube 51 and the inclined tube 54, in order to avoid the movable cylinder 46 interfering with the inside of the top blocking tube 51 and being stopped during rotation.

[0102] like Figure 17 As shown, the positioning cylinder 45 has a first through-hole 47, and the top blocking tube 51 has a second through-hole 48, as... Figure 19 As shown, the inclined tube 54 has a third through-hole 49, and the first through-hole 47 corresponds to the second through-hole 48 and the third through-hole 49 respectively.

[0103] like Figure 15 As shown, the impact tube 53 passes through the first through-hole 47 and the second through-hole 48 and enters the top blocking tube 51, as... Figure 19 As shown, the bottom blocking tube 52 passes through the first through-hole 47 and the third through-hole 47 and enters the impact tube 53, as... Figure 18 As shown, a connecting shaft 416 is provided on the side of the movable cylinder 46, and the movable cylinder 46 is rotatably mounted on the inner wall of the first through-hole 47 via the connecting shaft 416.

[0104] In this invention, the movable cylinder 36 can be rotated to adjust the angle between itself and the positioning cylinder 45, thereby adjusting according to the previously calculated pipe position.

[0105] Since the thickness of the drainage permeable layer 2 is smaller than the width, the inclination of the pipe in the present application is basically small, and the angle between the positioning cylinder 45 and the movable cylinder 46 is small. In order to avoid the rotation adjustment of the movable cylinder 46 by the positioning cylinder 45 from causing stopping, the length of the second through hole 48 and the third through hole 49 is longer than the length of the first through hole 47, and the length of the first through hole 47 is the same as the length of the positioning cylinder 45.

[0106] In the above embodiment, the first through hole 47 extends from the head to the tail along the direction of the positioning cylinder 45, that is, the movable cylinder 46 can be freely rotationally adjusted on the positioning cylinder 45, but in the present embodiment, the second through hole 48 and the third through hole 49 have a certain length limit, which limits the adjustment angle of the corresponding pipe.

[0107] In order to avoid other materials in the drainage permeable layer 2 from entering the pipe through the second through hole 48 and the third through hole 49, the length of the second through hole 48 and the third through hole 48 is determined based on the angle calculation and pipe position calculation each time, so that the impact pipe 53 just abuts on the second through hole 48 to close the second through hole 48, and the bottom blocking pipe 52 just abuts on the third through hole 49 to close the third through hole 49.
