Description

Technical Field

[0001] This utility model belongs to the field of mountain road technology, and in particular relates to a road cross-section structure for mountain roads. Background Technology

[0002] Mountain roads are a type of road specifically designed to traverse mountainous terrain. They are characterized by winding and tortuous horizontal alignments and steep longitudinal gradients. They are mainly used to connect mountain towns and villages. Although they are expensive to build, they are crucial to local transportation.

[0003] Chinese patent CN222313683U discloses a road structure for mountain highways. The patent describes a structure comprising a pavement structure, a roadbed excavation slope, a first roadbed edge structure located on the water-facing side of the roadbed excavation slope, a roadbed fill slope, and a second roadbed edge structure located on the upper part of the roadbed fill slope. The first and second roadbed edge structures are respectively located on both sides of the road structure. The first roadbed edge structure includes, from bottom to top, a cushion layer, an anti-erosion layer, a riprap connecting layer, and a drainage structure layer. The beneficial effects of this invention are: the first roadbed edge structure can protect the interior of the roadbed below the pavement structure, resisting the strong downcutting effect of floods and preventing direct erosion of the roadbed by water flow, thus avoiding roadbed hollowing and collapse; on the other hand, by designing upper drainage ditches, it can effectively remove surface water from the roadbed, preventing surface water from affecting roadbed stability and improving the durability and service life of the highway.

[0004] However, the above-mentioned scheme is not suitable for simple filtration of drainage. When it rains, rainwater will carry some soil and some gravel into the drainage ditch, which may block the drainage pipe or outlet, making drainage not timely and smooth, and thus affecting the stability of the roadbed. Therefore, it is necessary to design a road cross-section structure for mountain roads. Summary of the Invention

[0005] This utility model provides a road cross-section structure for mountain highways, aiming to solve the problem that some currently used road cross-section structures are inconvenient for simple drainage filtration.

[0006] This utility model is implemented as follows: a road cross-section structure for mountain highways includes a cement reinforcement slab; a gravel roadbed fixedly connected to the top of the cement reinforcement slab, a concrete pavement fixedly connected to the top of the gravel roadbed, and protective posts fixedly connected at equal intervals on one side of the top of the concrete pavement; a drainage ditch fixedly connected to the other side of the concrete pavement and the gravel roadbed, and drainage pipes fixedly connected at equal intervals on one side of the bottom of the drainage ditch; and a filter assembly assembled on the inner wall of the drainage ditch, the filter assembly being used to filter sand and gravel impurities.

[0007] Preferably, the filter assembly includes: slots equally spaced on one side of the inner wall of the drainage ditch; and a filter frame movably connected inside the drainage ditch, with a locking block fixedly connected to the upper end of one side of the filter frame.

[0008] Preferably, the upper end of one side of the inner wall of the filter frame is arc-shaped, and the other side of the inner wall of the filter frame is inclined.

[0009] Preferably, a fixing plate is fixedly connected to the other side of the top of the filter frame, and the fixing plate is arc-shaped.

[0010] Preferably, the card block and the inside of the card slot form an engaging structure, and the card slot and the card block are convex in shape.

[0011] Preferably, a baffle plate is fixedly connected to one end of the inner wall of the drainage pipe, and the length of the drainage pipe is greater than the width of the concrete pavement and the gravel roadbed.

[0012] Preferably, the top of the concrete pavement is sloping, and the bottom of the concrete pavement is located on the side away from the drainage ditch.

[0013] Preferably, the bottom end of the cement-reinforced slab is fixedly connected with reinforcing piles at equal intervals, and the reinforcing piles are distributed in a triangular pattern at the bottom end of the cement-reinforced slab.

[0014] Compared with related technologies, the road cross-section structure for mountain highways provided by this utility model has the following beneficial effects: Using a filter frame to shield and filter one end of the drainage pipe prevents impurities such as sand and gravel from entering the drainage pipe along with the rainwater in the drainage ditch, thus preventing blockage. This ensures smooth drainage of rainwater and prevents excessive accumulation of rainwater in the mountain soil due to blockage, which could affect the stability of the road or cause rainwater to overflow from the top of the drainage ditch onto the concrete pavement surface.

[0015] By utilizing the sloping top of the concrete pavement, rainwater on the concrete pavement surface can be drained more quickly and smoothly through the gaps between the guard posts. Rainwater flowing down from the mountain surface enters the drainage ditch and is then discharged through the drainage pipe. This facilitates timely and rapid drainage of rainwater, preventing rainwater from accumulating on the concrete pavement surface and causing traffic disruptions or safety hazards caused by roadbed erosion. At the same time, a shield is installed at one end of the drainage pipe to prevent small animals from accidentally climbing into the drainage pipe and getting stuck. Attached Figure Description

[0019] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0020] A preferred embodiment of the road cross-section structure for mountain highways provided by this utility model is, for example... Figures 1 to 5 As shown: A road cross-section structure for mountain highways includes a cement reinforcement slab 5; a gravel roadbed 3 fixedly connected to the top of the cement reinforcement slab 5, a concrete pavement 2 fixedly connected to the top of the gravel roadbed 3, and guard posts 1 fixedly connected at equal intervals on one side of the top of the concrete pavement 2; a drainage ditch 8 fixedly connected to the other side of the concrete pavement 2 and the gravel roadbed 3, and drainage pipes 4 fixedly connected at equal intervals on one side of the bottom of the drainage ditch 8; and a filter assembly 7 assembled on the inner wall of the drainage ditch 8, which is used to filter sand and gravel impurities.

[0021] It should be noted that some existing road cross-section structures used for mountain roads still have certain shortcomings in actual use. In the comparison document, when it rains, rainwater will carry some soil and some gravel into the drainage ditch 8, which may block the drainage pipe 4 or the drain outlet, making drainage not timely and smooth, and thus affecting the stability of the roadbed.

[0022] In a further preferred embodiment of the present invention, the filter assembly 7 includes: slots 703 equally spaced on one side of the inner wall of the drainage ditch 8; a filter frame 701 movably connected inside the drainage ditch 8, and a locking block 704 fixedly connected to the upper end of one side of the filter frame 701.

[0023] In this embodiment, the filter frame 701 is used to shield and filter one end of the drain pipe 4, preventing impurities such as sand and gravel in the rainwater inside the drainage ditch 8 from entering the drain pipe 4 and causing blockage. At the same time, the filter frame 701 can also store some of the filtered sand and gravel, thereby reducing the scouring force of rainwater on the filter frame 701. In addition, the filter frame 701 can be slid out for cleaning or replacement by using the sliding of the locking block 704 and the locking groove 703.

[0024] In a further preferred embodiment of the present invention, the upper end of one side of the inner wall of the filter frame 701 is arc-shaped, and the other side of the inner wall of the filter frame 701 is inclined.

[0025] In this embodiment, the filter frame 701 with its inner wall sloped is used so that the falling sand and gravel can be more concentrated on one side inside the filter frame 701.

[0026] In a further preferred embodiment of the present invention, a fixing plate 702 is fixedly connected to the other side of the top of the filter frame 701, and the fixing plate 702 is arc-shaped.

[0027] In this embodiment, an arc-shaped fixing plate 702 is used to serve as a handle, thereby facilitating the removal of the filter frame 701 via the fixing plate 702.

[0028] In a further preferred embodiment of the present invention, the card block 704 and the card slot 703 form an engaging structure, and the card slot 703 and the card block 704 are convex in shape.

[0029] In this embodiment, the engagement between the convex locking block 704 and the locking groove 703 improves the firmness and stability of the engagement between the filter frame 701 and the inside of the drainage ditch 8.

[0030] In a further preferred embodiment of this utility model, a baffle plate 9 is fixedly connected to one end of the inner wall of the drainage pipe 4, and the length of the drainage pipe 4 is greater than the width of the concrete road surface 2 and the gravel roadbed 3.

[0031] In this embodiment, the baffle 9 is used to prevent small animals from accidentally climbing into the drain pipe 4.

[0032] In a further preferred embodiment of the present invention, the top of the concrete pavement 2 is inclined, and the bottom of the concrete pavement 2 is located on the side away from the drainage ditch 8.

[0033] In this embodiment, the concrete pavement 2 with a sloping top can quickly and smoothly drain rainwater from its surface.

[0034] In a further preferred embodiment of this utility model, reinforcing piles 6 are fixedly connected at equal intervals to the bottom end of the cement reinforcing plate 5, and the reinforcing piles 6 are distributed in a triangular pattern at the bottom end of the cement reinforcing plate 5.

[0035] In this embodiment, the overall structural strength is improved by using triangularly distributed reinforcing piles 6.

[0036] In summary, the top of the concrete pavement 2 is sloped, which facilitates the guidance of rainwater falling onto the top of the concrete pavement 2, preventing rainwater from accumulating at the top of the concrete pavement 2 and causing driving safety issues. In addition, the drainage ditch 8 can collect rainwater flowing from the mountainside, preventing it from directly washing onto the surface of the concrete pavement 2. The filter frame 701 is used to filter the rainwater entering the drainage ditch 8, and then it is discharged through the drainage pipe 4, thereby improving its drainage effect. Furthermore, the filter frame 701 can prevent sand and gravel from clogging the drainage pipe 4 and affecting the drainage rate, thereby preventing rainwater from overflowing from the drainage ditch 8 due to untimely drainage, or rainwater from accumulating in the soil and affecting the reliability of the road structure. The shield 9 can also prevent small animals from accidentally climbing into the drainage pipe 4 and getting stuck and blocked.
