Description

Technical Field

[0001] This utility model relates to the field of embankment seepage treatment technology, specifically to a device for treating embankment seepage in highway reconstruction and expansion projects. Background Technology

[0002] The embankment seepage treatment device for highway reconstruction and expansion projects is a systematic drainage structure designed for different seepage points of old embankments. Its core function is to intercept and guide seepage water to prevent it from wetting the newly filled roadbed, thereby reducing the settlement difference between the old and new roadbeds and enhancing the stability of the joint.

[0003] A structure for effectively treating seepage and stagnant water in roadbeds and pavements under low embankments, disclosed in CN222251565U, is installed on highways to drain accumulated water. This structure utilizes a double-ditch stacked road drainage system. The upper ditch serves both as a drainage system and as a barrier to prevent external groundwater from flowing into the roadbed. Seepage water inside the roadbed is drained into blind ditches and then into the upper drainage ditch by the waterproof geotextile at the bottom of the roadbed and its diversion effect. The method of using double-ditch stacked roadbeds with geotextile waterproofing at the bottom reduces the need for secondary excavation of the side ditches.

[0004] In actual use, existing roadbed seepage treatment devices still cannot collect seepage at different heights of the embankment, making it difficult to drain the seepage inside the embankment. As a result, the seepage accumulates inside the embankment, which can easily cause the embankment to collapse and affect road safety. Summary of the Invention

[0005] The purpose of this invention is to provide a device for treating seepage in embankments during highway reconstruction and expansion projects. This device can effectively solve the problem mentioned in the background art of the inability to conveniently collect seepage at different heights of the embankment, which can easily lead to embankment collapse.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a seepage treatment device for embankments in highway reconstruction and expansion projects, comprising an embankment body, and further comprising:

[0007] A collection mechanism located at the top of the inner side of the embankment body and a drainage mechanism located at the bottom of the collection mechanism;

[0008] The collection mechanism includes a first vertical pipe, two sets of the first vertical pipes are respectively inserted into the slopes on both sides of the embankment body, a second vertical pipe is provided on the opposite side of the two sets of the first vertical pipes, a third vertical pipe is provided on the opposite side of the two sets of the second vertical pipes, and multiple collection pipes are fixedly installed at both ends of the first vertical pipe and the second vertical pipe.

[0009] The drainage mechanism includes multiple drainage pipes, which are fixedly installed at the bottom of two adjacent first vertical pipes. The top sides of the drainage pipes are fixedly connected to the bottom of two adjacent second vertical pipes and third vertical pipes, respectively. Two connecting pipes are fixedly installed between two adjacent drainage pipes, and multiple water collection holes are opened at the top of the connecting pipes.

[0010] Preferably, the embankment body includes a roadbed filler layer, and multiple installation holes are provided on both sides of the roadbed filler layer. Multiple fixing holes are provided at both ends of the inner walls of the two sets of installation holes at the top and middle positions.

[0011] Preferably, the two sets of mounting holes at the top are respectively fitted onto the outside of the two sets of first vertical tubes, the two sets of mounting holes in the middle are respectively fitted onto the outside of the two sets of second vertical tubes, and the two sets of mounting holes at the bottom are respectively fitted onto the outside of the two sets of third vertical tubes.

[0012] Preferably, multiple fixing holes are respectively fitted onto the outside of adjacent collecting pipes, multiple seepage holes are opened at the top of the collecting pipes, and multiple fixing grooves are opened at the bottom of the roadbed filler layer.

[0013] Preferably, the inner walls of the plurality of fixed grooves are respectively fitted onto the outer sides of the plurality of drainage pipes, and the longitudinal dimension of the drainage pipes is the same as the bottom width dimension of the roadbed filler layer.

[0014] Preferably, the top end faces of the first, second, and third vertical pipes are on the same plane as the two side slopes of the roadbed filler layer.

[0015] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0016] 1. The first, second, and third vertical pipes can collect the flowing water on both sides of the embankment. At the same time, the collection pipes at both ends of the first and second vertical pipes can collect seepage water from different locations inside the subgrade filler layer, realizing full-section seepage water collection of the embankment. The seepage holes enable the collection pipes to stably collect the seepage water. Then, multiple drainage pipes can discharge the seepage water collected by the collection mechanism from inside the embankment, thereby preventing seepage water from eroding the embankment and ensuring the stability of the embankment.

[0017] 2. Two adjacent drainage pipes can be connected through the connecting pipe. The water collection hole opened at the top of the connecting pipe can further collect the seepage water inside the subgrade fill layer, thereby preventing the seepage water from accumulating at the bottom of the subgrade fill layer, reducing the erosion of the bottom of the subgrade fill layer by the seepage water, and ensuring the safety of the embankment itself.

[0018] 3. The prefabricated design of the mounting holes and fixing holes allows the drainage system to be constructed simultaneously with the embankment filling, which shortens the construction period compared to the traditional later excavation and installation process.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] This utility model provides, for example Figure 1-6The highway reconstruction and expansion project embankment seepage treatment device shown includes the embankment body 1, and also includes:

[0032] The collection mechanism 2 is located on the top inner side of the embankment body 1, and the drainage mechanism 3 is located at the bottom of the collection mechanism 2.

[0033] To facilitate the collection of seepage water inside the embankment body 1, the collection mechanism 2 includes a first vertical pipe 201. Two sets of first vertical pipes 201 are respectively inserted into the slopes on both sides of the embankment body 1. A second vertical pipe 202 is provided on the opposite side of each set of first vertical pipes 201, and a third vertical pipe 203 is provided on the opposite side of each set of second vertical pipes 202. Multiple collection pipes 204 are fixedly installed at both ends of the first vertical pipes 201 and second vertical pipes 202. Seepage water from the slopes on both sides of the embankment body 1 can be collected through the first vertical pipes 201, second vertical pipes 202, and third vertical pipes 203. Seepage water around the first vertical pipes 201 and second vertical pipes 202 can be collected through the collection pipes 204 at both ends of the first vertical pipes 201 and second vertical pipes 202, thereby effectively collecting seepage water inside the embankment body 1. Preferably, the collection pipes 204 are provided with guide ribs to guide capillary water to converge into the vertical pipes.

[0034] In order to facilitate the discharge of the collected seepage water from the inside of the embankment body 1, the drainage mechanism 3 includes multiple drainage pipes 301. The drainage pipes 301 are fixedly installed at the bottom of two adjacent first vertical pipes 201. The drainage pipes 301 can be set with a longitudinal slope of 1%-2% to form gravity drainage. Preferably, the inner wall of the drainage pipes 301 can be coated with a nano hydrophobic coating. The first vertical pipe 201 and the drainage pipe 301 can be connected by flanges. The top two sides of the drainage pipe 301 are fixedly connected to the bottoms of two adjacent second vertical pipes 202 and third vertical pipes 203, respectively. Two connecting pipes 302 are fixedly installed between adjacent drainage pipes 301. Multiple water collection holes 303 are opened at the top of the connecting pipes 302. Seepage water collected by the first vertical pipes 201, second vertical pipes 202, and third vertical pipes 203 can be discharged from the inside of the embankment body 1 through the drainage pipes 301. The connecting pipes 302 can connect adjacent drainage pipes 301, and the water collection holes 303 at the top of the connecting pipes 302 can collect seepage water from the bottom of the embankment body 1, allowing it to be discharged through the drainage pipes 301. This prevents surface seepage water from eroding the embankment body 1, ensuring the stability of the embankment body 1 and thus ensuring road safety. The vertical pipes and drainage pipes in this invention can be made of HDPE double-wall corrugated pipes to meet the pressure resistance requirements. The connecting pipe 302 not only drains water, but its mesh structure also enhances the overall rigidity of the roadbed, which can reduce differential settlement between the old and new roadbeds.

[0035] To facilitate the installation of the collection mechanism 2, the embankment body 1 includes a roadbed filler layer 101. Multiple installation holes 102 are provided on both sides of the slope of the roadbed filler layer 101. Multiple fixing holes 103 are provided at both ends of the inner walls of the two sets of installation holes 102 at the top and middle positions. The two sets of installation holes 102 at the top are respectively fitted onto the outside of the two sets of first vertical pipes 201, the two sets of installation holes 102 at the middle position are respectively fitted onto the outside of the two sets of second vertical pipes 202, and the two sets of installation holes 102 at the bottom are respectively fitted onto the outside of the two sets of third vertical pipes 203. The first vertical pipes 201, second vertical pipes 202 and third vertical pipes 203 can be installed and fixed through the installation holes 102, so that the first vertical pipes 201, second vertical pipes 202 and third vertical pipes 203 can collect the seepage water on the surface of the roadbed filler layer 101.

[0036] To fully collect and drain seepage water from the subgrade filler layer 101, multiple fixing holes 103 are respectively fitted onto the outside of adjacent collection pipes 204. Multiple seepage holes 205 are opened at the top of the collection pipes 204, and multiple fixing grooves 104 are opened at the bottom of the subgrade filler layer 101. The inner walls of the multiple fixing grooves 104 are respectively fitted onto the outside of multiple drainage pipes 301. The longitudinal dimension of the drainage pipes 301 is the same as the bottom width dimension of the subgrade filler layer 101. The top end faces of the first vertical pipe 201, the second vertical pipe 202, and the third vertical pipe 203 are on the same plane as the two side slopes of the subgrade filler layer 101. The fixing holes 103 can be used to install the collection pipes 204, so that the seepage holes 205 can collect the seepage water from the surrounding area. The fixing grooves 104 can be used to install and fix the drainage pipes 301. The seepage water collected by the first vertical pipe 201, the second vertical pipe 202, and the third vertical pipe 203 can be discharged from the inside of the subgrade filler layer 101 through the drainage pipes 301.

[0037] During road widening, according to the construction requirements of the embankment body 1, multiple first vertical pipes 201 are installed on both sides of the drainage pipe 301. Then, a second vertical pipe 202 is installed on the opposite side of the two first vertical pipes 201, and a third vertical pipe 203 is installed on the opposite side of the two second vertical pipes 202. Then, two connecting pipes 302 are fixedly installed between two adjacent drainage pipes 301. Then, multiple collection pipes 204 are installed on the outer sides of both ends of the first vertical pipes 201 and the second vertical pipes 202. Then, filler is applied to the outside of the collection mechanism 2 and the drainage mechanism 3, so that the roadbed filler layer 10... 1 can cover the outside of the collection mechanism 2 and the drainage mechanism 3, so that the installation hole 102 is formed inside the roadbed filling layer 101 and is sleeved on the outside of the first vertical pipe 201, the second vertical pipe 202 and the third vertical pipe 203. At the same time, a fixing hole 103 is formed on the outside of the collection pipe 204, thereby forming a fixing groove 104 on the outside of the drainage pipe 301. This allows the collection mechanism 2 and the drainage mechanism 3 to remain stable inside the roadbed filling layer 101, and at the same time, the top end face of the first vertical pipe 201, the second vertical pipe 202 and the third vertical pipe 203 is on the same plane as the slopes on both sides of the roadbed filling layer 101.

[0038] The seepage water around the top of the collection pipe 204 can be collected through the seepage hole 205. The first vertical pipe 201, the second vertical pipe 202 and the third vertical pipe 203 can collect the seepage water on the surface of the roadbed filler layer 101. Then, the collected seepage water can be discharged from the inside of the roadbed filler layer 101 through the drainage pipe 301. At the same time, the seepage water at the bottom of the roadbed filler layer 101 can be further collected through the water collection hole 303 opened at the top of the connecting pipe 302. This can prevent the seepage water from eroding the roadbed filler layer 101, ensure the stability of the roadbed filler layer 101, and thus ensure the safety of the road. This embodiment specifically solves the problem in the prior art that the inconvenience of collecting seepage water inside the embankment leads to the embankment being easily eroded by seepage water and collapsing.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model are included within the scope of protection of this utility model.
