Description

Technical Field

[0001] This invention relates to the field of highway construction technology, and in particular to the structure, system and construction method of a permanent and temporary fiberglass composite trough for highways. Background Technology

[0002] The statements in this section are merely background information related to the present invention and do not necessarily constitute prior art.

[0003] Typically, after the water-stabilized layer and lower layer of a highway are laid, curb stones and permanent concrete drainage channels are installed. This creates a "gap period" between the construction of the water-stabilized layer and the surface layer. Under extreme rainfall, this period is prone to slope damage due to two main reasons: First, improper construction sequence. If the permanent drainage channel is constructed prematurely, before the road surface is laid, its inlet is usually 10-20cm higher than the top surface of the unpaved roadbed. During rainfall, water cannot drain smoothly into the drainage channel and instead seeps down through the gaps in the curb stones. There are two main causes of water damage: First, hidden runoff. This runoff diffuses within the water-stabilized layer and seeps out from weak points on the slope, continuously eroding the slope soil and gradually weakening its structure, eventually leading to slope collapse or erosion. Second, silty sand and silty soil subgrades inherently lack erosion resistance. These soils have fine particles and loose pore structures, making them inherently weak against water erosion. Under extreme rainfall conditions, rainwater can quickly infiltrate and saturate the soil, significantly reducing its structural strength. Internal erosion can induce localized collapses or even landslides, resulting in severe water damage. This type of water damage is often characterized by rapid development and wide-ranging destruction. When these two factors combine, they further exacerbate the severity of water damage, posing a significant threat to the stability of the subgrade during construction. In other words, the existing concrete chutes are designed to drain surface water, but their drainage depth is relatively shallow, making them prone to overflow.

[0004] In addition, most existing rapid flow channels are precast concrete channels, which have several prominent problems in practical applications: First, they are difficult to construct due to their heavy weight, making them laborious to transport and difficult to install; during long-term use, they are prone to severe weathering due to wind and rain, and the use of de-icing agents in winter can cause chloride ions to corrode the concrete surface; when the rapid flow channel is damaged, repair is difficult, and if not handled properly in time, it can easily lead to local erosion of the slope; more seriously, due to their heavy weight, they are prone to subsidence and collapse under extreme rainfall conditions, which can cause cracks in the rapid flow channel and even lead to the risk of landslides.

[0005] Existing technologies also include polymer composite material drainage channels. Although these drainage channels can solve the problems of poor durability, small drainage volume, and poor sealing of traditional drainage channels, their design purpose is also to solve the drainage problem of road surface layers.

[0006] To address the aforementioned issues, temporary sluices are installed on the road surface. However, these temporary sluices have poor construction techniques, large gaps between them and the road surface, and are prone to erosion and hollowing. In summary, none of the three types of rapid flow channels can solve the problem of road surface drainage during the "gap period". Summary of the Invention

[0007] To address the shortcomings of existing technologies, the purpose of this invention is to provide a permanent and temporary combined fiberglass material trough structure for highways, ensuring the effectiveness of roadbed drainage under extreme rainfall conditions and avoiding slope damage caused by unreasonable construction procedures or temporary and permanent drainage processes.

[0008] To achieve the above objectives, the present invention is implemented through the following technical solution: The highway-use permanent and temporary fiberglass material rapid flow channel structure includes an inlet channel, a drainage channel, a turning head, and an outlet channel connected in sequence. The rapid flow channel is made of high-polymer fiberglass material. The bottom surface of the inlet channel is flush with the bottom surface of the water-stabilized layer. The top surface of the inlet channel near the curb extends beyond the top of the surface layer. The connection between the inlet channel and the water-stabilized layer is sealed. The curb at the inlet side of the inlet channel is disconnected. The inlet side of the inlet channel is open so that water from the surface layer flows into the inlet channel. Both sides of the inlet side of the inlet channel are connected to the curb through inlet connectors so that water from the surface layer flows into the inlet channel under the guidance of the inlet connectors.

[0009] As described above, in the highway permanent and temporary fiberglass material rapid flow channel structure, the top surface of the water inlet channel body near the curb is flush with the top of the curb. The connection between the water inlet channel body and the water-stabilized layer is sealed with mortar. In this way, the rapid flow channel structure can still be used normally after the surface layer is fully constructed, so that both permanent and temporary rapid flow channels can be used normally. The depth of the water inlet trough is 37cm on the side closest to the curbstone, and 15cm-30cm on the other side. The depth of the water inlet trough on the side furthest from the curbstone is the same as the depth of the drainage trough.

[0010] As described above, in the highway permanent and temporary combined fiberglass material rapid flow channel structure, the bottom of the inlet connector is located below the curb stone, one side of the inlet connector is fixedly connected to the end face of the curb stone, and the other side of the inlet connector is fixedly connected to the side of the inlet channel body.

[0011] As described above, the highway permanent and temporary combined fiberglass material rapid flow channel structure includes a water inlet connector comprising a support plate, which is placed at the bottom of the curb stone. The end of the support plate supports a first plate and a second plate. Both the first plate and the second plate are perpendicularly connected to the support plate. The first plate and the second plate are connected in an L-shaped structure. The first plate is connected to the curb stone, and the second plate is fixedly connected to the side of the water inlet channel body.

[0012] The highway-use permanent and temporary fiberglass material rapid flow channel structure described above also includes a first anti-fall water component. The first anti-fall water component is placed between the water inlet tank and the surface layer end side. One side of the first anti-fall water component is in contact with the water inlet tank, and the height of the other side of the first anti-fall water component is adjustable. The first anti-fall water component has a downward slope structure or the first anti-fall water component is a plate-shaped structure.

[0013] As described above, in the highway permanent combined fiberglass material rapid flow channel structure, the first anti-fall water component is provided with support rods on both sides near the surface layer. The support rods are provided with multiple protrusions or grooves. The two sides of the first anti-fall water component are provided with recesses or protrusions. The protrusions of the support rods can be inserted into the recesses on the side of the first anti-fall water component, and the protrusions can be inserted into the grooves. When the first anti-fall water component is a plate-shaped structure, it can be directly inserted into the groove of the support rod.

[0014] The highway-use permanent and temporary fiberglass material rapid flow channel structure described above also includes a second anti-fall water component. The second anti-fall water component is in contact with one end of the first anti-fall water component. The second anti-fall water component is disposed in the water inlet tank and is located near the water inlet side of the water inlet tank. The second anti-fall water component has a downward-facing slope structure.

[0015] As described above, the highway permanent and temporary combined fiberglass material rapid flow channel structure, from the direction of the water inlet channel to the drainage channel, the water inlet channel includes a first section, a second section and a third section connected in sequence, the bottom surface of the first section is a plane, the bottom surface of the second section is a slope section, the bottom surface of the third section is a plane section, and the depth of the first section is deeper than the depth of the third section. From the side of the water inlet trough closest to the curb to the other side, the depth of the second section gradually decreases, and the depth of the third section gradually decreases. The angle between the second segment and the first segment is 120°-150°.

[0016] Secondly, a rapid flow channel system employs multiple rapid flow channel structures made of composite fiberglass material for highway use, wherein the distance between two adjacent rapid flow channel structures is less than or equal to 150 meters.

[0017] Thirdly, the present invention also provides a construction method for a highway-use permanent-temporary bonded fiberglass material rapid flow channel structure, including the following: Excavate the inlet trench to a set distance below the water-stabilized layer. First, lay a mortar cushion layer, then place the inlet tank body. The bottom surface of the inlet tank body is flush with the bottom surface of the water-stabilized layer. Seal the connection between the inlet tank body and the water-stabilized layer. One end of the inlet connector is connected to the curbstone, and the other end is connected to the side of the inlet trough. Excavate trenches along the slope direction to place drainage troughs, bends, and outlet troughs. The drainage troughs are connected to the bends. During the installation of the bends, a mortar pad of a set thickness is laid on the bottom surface of the bends, and the bends are connected to the outlet troughs.

[0018] The beneficial effects of the present invention are as follows: 1) This invention provides a rapid flow channel, which includes an inlet channel body. The sides of the inlet channel body are connected to the curb stone through inlet connectors. The bottom of the inlet channel body is lower than the surface layer and flush with the bottom surface of the water-stabilized layer, ensuring the depth of the inlet side of the inlet channel body. In this way, before the surface layer is completed, the water on the surface of the surface layer can smoothly enter the rapid flow channel and flow out, preventing large-area water accumulation and avoiding the problem of water seeping down the curb stone gaps to form hidden runoff and eroding the slope soil.

[0019] 2) The inlet connector structure of this invention is reasonably set. The support plate of the inlet connector can be placed below the curbstone. The first plate of the inlet connector is connected to the end face of the curbstone, and the second plate is connected to the side of the inlet trough body to ensure the stable setting of the inlet connector. The setting of the inlet connector can effectively guide the water between the rapid flow trough and the surface layer, and prevent the water at the surface layer from flowing out through the gap between the rapid flow trough and the curbstone.

[0020] 3) The water inlet trough structure is reasonably designed in this invention. The first drainage depth can reach the water-stabilized layer. However, because of the increased depth, the water flowing at the surface layer can smoothly enter the water inlet trough before the surface layer is constructed. When the water flow is large, the drainage capacity of the water inlet trough is guaranteed, so that the water on the road surface can be quickly discharged into the water inlet trough, ensuring the rapid flow of water on the road surface.

[0021] 4) The present invention provides a rapid flow channel structure, which is provided with a first anti-fall water component and a second anti-fall water component. The first anti-fall water component is located between the water inlet tank and the end side of the surface layer, and the second anti-fall water component is located in the water inlet tank. The two can contact each other, so that the water flow can flow downward along the surface of the first anti-fall water component and the second anti-fall water component. Moreover, as the surface layer is constructed layer by layer, the tilt angle of the first anti-fall water component can be adjusted to ensure the anti-fall water effect.

[0022] 5) The rapid flow channel in this invention is made of high-molecular glass fiber composite material, which has durability and corrosion resistance. Combined with the construction of curb stones, it can achieve seamless connection between the rapid flow channel and the surrounding structure, avoiding the hidden danger of leakage in the later stage from the construction source. Moreover, compared with the rapid flow channel of traditional concrete structure, it has the advantages of energy saving, environmental protection and low carbon. Attached Figure Description

[0031] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the invention. Unless otherwise specified, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0032] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of exemplary embodiments according to the invention. As used herein, unless otherwise expressly indicated by the invention, the singular form is also intended to include the plural form. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof. As described in the background section, in the prior art, poor drainage of the road surface during subgrade construction leads to slope damage caused by water. In order to solve the above technical problems, this invention proposes a permanent and temporary combined fiberglass material rapid flow channel structure for highways.

[0033] Example 1 In a typical embodiment of the present invention, reference is made to Figure 1 As shown, the highway-use permanent and temporary fiberglass material rapid flow channel structure includes an inlet channel 5, a drainage channel 6, a turning head 7, and an outlet channel 8 connected in sequence. The bottom surface of the inlet channel 5 is flush with the bottom surface of the water-stabilized layer 3. The connection between the inlet channel 5 and the water-stabilized layer 3 is sealed with mortar. The bottom surface of the inlet channel 5 is set lower than the bottom surface of the surface layer 2. The inlet side of the inlet channel 5 is open so that rainwater from the road surface can flow into the inlet channel. The two sides of the inlet side of the inlet channel are connected to the curb stone 12 through inlet connectors 1, so that the water flow from the surface layer can flow into the inlet channel under the guidance of the inlet connectors. The curb stone 12 is supported by the curb stone base 17. The curb stone on the inlet side of the inlet channel 5 is disconnected to ensure that the water flow is directed into the inlet channel 5.

[0034] The top surface of the water inlet trough 5, which is close to the curbstone, is flush with the top of the curbstone. This way, after the top structure above the surface layer is completed, the trough structure can still be used normally, enabling both permanent and temporary troughs to be used normally.

[0035] The rapid flow channel is made of high-polymer fiberglass composite material, which is durable and corrosion-resistant. The rapid flow channel is installed after the water-stabilized layer is laid and the curb is constructed. At this time, the water-stabilized layer has formed a stable load-bearing foundation. Combined with the curb construction, the rapid flow channel can be seamlessly connected with the surrounding structure, avoiding the risk of leakage in the later gaps from the construction source. It effectively solves the problem of water seepage during the construction period - when it rains, the water on the road surface or water-stabilized layer can flow directly into the rapid flow channel, completely eliminating the situation in traditional processes where water seeps down along the gaps in the curb to form hidden runoff and then erodes the slope, cutting off the cause of water damage at the root. On the other hand, to ensure long-term stability, after the surface layer is laid, the side of the water inlet trough 5 closest to the curb stone is sealed with mortar between it and the water-stabilized layer to prevent water from flowing through the gap between the water inlet trough and the water-stabilized layer and causing erosion of the slope structure.

[0036] It is easy to understand that the inlet side of the water inlet trough 5 is open so that rainwater from the road surface can flow into the water inlet trough 5. The top of the inlet connector 1 is flush with the top of the water inlet trough 5 or the top of the inlet connector 1 is lower than the top of the water inlet trough 5. The bottom surface of the inlet connector 1 is higher than the bottom surface of the water inlet trough 5. The inlet connector 1 and the bottom surface of the water inlet side of the water inlet trough 5 are both fixed to the support block. The support block is located on the side of the top of the large-particle permeable layer and the base layer. One end of the inlet connector 1 is fixed to the side of the water inlet trough 5, and the other end of the inlet connector 1 is fixed to the end face of the curb stone 12. The inlet connector 1 is set to better connect the water inlet trough 5 and the curb stone 12, reduce the reliance on cement for sealing, and improve construction efficiency.

[0037] Specifically, the width of the inlet trough 5 near the curb is greater than the width of the other side, i.e., the inlet trough 5 is V-shaped. From the inlet trough to the drainage trough, the inlet trough includes a first section 14, a second section 15, and a third section 16 connected in sequence. The bottom surface of the first section 14 is flat, the bottom surface of the second section 15 is sloping, and the bottom surface of the third section 16 is flat. The bottom surfaces of the first section 14 and the third section 16 are parallel to each other. The angle formed between the second section and the first section is 120°-150°. The minimum drainage depth of the first section is set at 30cm, which allows the inlet trough to... Although the top of the first section is higher than the already constructed surface layer, the increased depth allows water from the top of the surface layer to still smoothly enter the inlet channel. This ensures the drainage capacity of the inlet channel even with large water flows, allowing surface water to drain quickly and flow rapidly. Considering cost and drainage capacity, the drainage depth of the first section 14 of the inlet channel 5 is set at 37cm. The depth gradually decreases according to the slope angle, reaching 15cm-30cm at the connection point with the drainage channel, with 20cm being the preferred depth. The depth of the first section 14 and the third section 16 of the inlet channel is designed to allow for the installation of a permanent and temporary combined rapid flow channel after the water-stabilized layer is laid, ensuring permanent drainage of the road surface until the surface layer is completed.

[0038] refer to Figure 2 and Figure 3As shown, the inlet connector 1 includes a support plate 11. The end of the support plate 11 supports a first plate 9 and a second plate 10. Both the first plate 9 and the second plate 10 are perpendicularly connected to the support plate 11. The first plate 9 is provided with an opening, which can be an elongated hole. Fasteners such as expansion bolts pass through the opening 13 and are connected to the end face of the curbstone 12. The second plate contacts and is fixed to the side of the inlet trough (which can be fastened with bolts). The inlet connector 1 has a reasonable structure and plays an effective connecting role, which facilitates the smooth flow of water from the road surface to the inlet trough.

[0039] Specifically, the side of the support plate 11 extends beyond the second plate 10, so that the support plate 11 is placed on the bottom surface of the curb stone 12, ensuring the stability of the inlet connector 1.

[0040] In some examples, considering the service life of the inlet connector 1, a third plate is provided on the top of the inlet connector. The third plate connects the first plate 9 and the second plate 10. A reinforcing rib is also connected between the third plate and the first plate 9 to improve the structural strength of the inlet connector.

[0041] In addition, the existing structure is used for the turning head 7, the water outlet trough 8 and the drainage trough 6. The drainage trough 6 is provided with multiple sections. The end of the water outlet trough 8 away from the turning head 7 is set as a sloping structure to be flush with the side of the drainage ditch. The connection of each component in the rapid flow channel is sealed with weather-resistant sealing material.

[0042] To eliminate the height difference between the top of the surface layer and the inlet channel 5, prevent water flow from impacting the inlet channel 5 or the soil below, protect the rapid flow channel structure itself, and avoid secondary erosion of the slope by the drop, refer to Figure 4 As shown, the rapid flow channel structure also includes a first anti-fall water component 19. The first anti-fall water component 19 is placed between the inlet tank 5 and the end of the surface layer 2. One side of the first anti-fall water component 19 is in contact with the inlet tank 5. Considering that the surface layer 2 is constructed layer by layer, in order to follow the layer-by-layer construction of the surface layer 2, the height of the other side of the first anti-fall water component 19 is adjustable. In this way, as the surface layer 2 is gradually constructed, the height of the side of the first anti-fall water component 19 near the curb stone 12 can be adjusted, so that the angle of the first anti-fall water component 19 gradually increases to match the increase of the surface layer 2. The first anti-fall water component 19 has a downward slope structure, that is, the longitudinal section of the first anti-fall water component 19 is triangular, or the first anti-fall water component 19 is a plate-shaped structure. After the surface layer construction is completed, the side of the first anti-fall water component 19 near the inlet tank 5 is sealed to the bottom and side wall of the inlet tank 5 through existing sealant. Specifically, the first anti-fall component 19 is positioned at the center of the top side of the water inlet tank, providing space for the support rods 21. Support rods 21 are respectively installed on both sides of the first anti-fall component 19 near the surface layer 2. The support rods 21 are specifically located inside the water inlet connector 1, with a spacing between them and the curb stone 12. The bottom of the support rods 21 is inserted downwards to a predetermined depth, allowing for fixation of the support rods 21 during the mortar application process. (Refer to...) Figure 5 As shown, the support rod 21 is provided with multiple grooves 20, and the two sides of the first anti-fall water component 19 are respectively provided with protrusions 22. The protrusions 22 can be inserted into the grooves 20. As the surface layer 2 rises, the protrusions 22 of the first anti-fall water component 19 are inserted into the grooves of the support rod 21 at the corresponding height. The transverse cross section of the groove 20 is semi-circular, and the protrusions 22 can be hemispherical or rectangular blocks to facilitate the insertion of the protrusions 22 into the grooves 20 of the support rod 21. Of course, when the first anti-fall water component 19 is a plate-shaped structure, the first anti-fall water component can be directly inserted into the grooves 20 of the support rod to adjust the tilt angle of the first anti-fall water component 19.

[0043] In other examples, the support rod 21 is provided with multiple protrusions at different heights. The two sides of the first anti-fall water component 19 are respectively provided with recesses. The recesses on both sides of the first anti-fall water component 19 can be inserted into the protrusions of the support rod 21. As the surface layer 2 rises, the recesses of the first anti-fall water component 19 are inserted into the protrusions of the support rod 21 at the corresponding height. The protrusions can be hemispherical structures to facilitate insertion into the recesses of the first anti-fall water component 19.

[0044] In addition, the rapid flow channel structure also includes a second anti-fall water component 18. The top of the second anti-fall water component 18 contacts the bottom of the first anti-fall water component 19. The second anti-fall water component 18 is located in the water inlet tank body and is positioned near the water inlet side of the water inlet tank body 5. The second anti-fall water component 18 has a downward-facing sloping structure, and its longitudinal cross-section is also triangular. The second anti-fall water component 18 is sealed to the bottom and side wall of the water inlet tank body 5 using existing sealant to ensure the stable installation of the second anti-fall water component 18.

[0045] The rapid flow channel made of polymer materials has the characteristics of strong weather resistance, erosion resistance, and light weight. The rapid flow channel provided in this embodiment guides the water flow through the inlet connector and is equipped with a deeper inlet channel body. During rainfall, the surface water on the road surface is smoothly discharged into the rapid flow channel, preventing it from seeping down along the cracks in the curb stone to form hidden runoff that erodes the slope soil. It not only meets the temporary drainage needs during the construction period, but also serves as a permanent facility that can continue to play a role, achieving a combination of temporary and permanent facilities, and truly solving the water damage problem related to rapid flow channels from the root.

[0046] Example 2 This embodiment discloses a rapid flow channel system, which adopts the rapid flow channel structure of permanent and temporary fiberglass material for highways described in several embodiments.

[0047] To reasonably control the drainage spacing, adjacent rapid flow channels are arranged at a distance of less than or equal to 150 meters. This spacing is based on the optimized calculation of the road surface catchment area and runoff velocity, which can efficiently cover the roadbed area and ensure that the surface water on the road can be quickly collected and drained in time during extreme rainfall, thus preventing large-scale water accumulation.

[0048] Example 3 This embodiment discloses a permanent and temporary fiberglass-bonded rapid flow channel structure for highways, including the following: Excavate the inlet trench to the water-stabilized layer 3 (large particle permeable layer) and reach the base layer 4, for example, 15 cm below the water-stabilized layer. First, lay a mortar cushion layer with a thickness of more than 5 cm, and then place the inlet tank. The bottom surface of the inlet tank should be flush with the lower end of the large particle permeable layer. The connection between the inlet tank and the large particle permeable layer should be sealed with crack-resistant mortar. During the installation of the inlet connector, ensure that the inlet side of the rapid flow channel is level with the slope surface. After determining the installation angle of the rapid flow channel, one end of the connector is connected to the curb with an expansion bolt, and the other end is connected to the side of the inlet channel body. Use EPDM rubber gaskets at the connection to ensure a sealing effect. After the water-stabilized layer (large-particle permeable layer) is laid, during the curbstone installation stage, according to the shape of the inlet connector, a 50cm trench is dug at the shoulder and the bottom surface is compacted and covered with soil. Excavate a 30cm trench along the slope to place the drainage trough, turning head, and outlet trough. The drainage trough and inlet trough are connected using an overlapping tile joint and secured with galvanized bolts. Weather-resistant sealant is used to seal the joints between the components. During the installation of the turning head, a 5cm thick mortar pad is laid on the bottom surface of the turning head to ensure the stability of the rapid flow channel. Finally, the outlet trough is installed. In addition, the drainage ditch, the bend and the outlet ditch on both sides need to be fixed with anchor bolts (the anchor bolts pass through the drainage ditch, the bend and the outlet ditch and are fixed to the slope), and the soil should be backfilled and compacted. The construction method provided in this embodiment fixes both ends of the inlet connector to the curbstone to ensure firmness. At the same time, the bottom surface of the inlet trough is flush with the water-stabilized layer (large particle permeable layer), and a 5 cm mortar pad is laid on the bottom surface to prevent the rapid flow trough from settling. The entire rapid flow trough can be successfully installed smoothly.

[0049] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
