Description
Technical Field
[0001] This utility model relates to the field of highway engineering technology, specifically to a fiberglass rapid flow channel with a stress-relief sill in a highway subgrade drainage system. Background Technology
[0002] In the field of highway engineering, chutes, as a pavement drainage structure, are widely used in embankment sections of highways or ordinary roads, playing a crucial role in quickly diverting surface water to drainage ditches at the toe of the road slope. For example, the Chinese utility model patent "Fiberglass Chute" (patent number ZL202023185246.0) utilizes a prefabricated structure manufactured in a factory workshop. Rapid assembly is achieved through the cooperation of the access channel, the chute body, and cross-shaped pins, solving the problems of difficult construction and modification of traditional concrete chutes. It also offers advantages such as convenient disassembly and transportation. Since its introduction, this product has been used in multiple highways, basically meeting drainage requirements. However, long-term practice has revealed the following shortcomings:
[0003] The rapid flow channel lacks water flow direction markings, requiring manual direction determination during installation, which reduces installation efficiency; the anchor bolt holes are designed with an upward protrusion, resulting in the anchor bolt caps not being flush with the outer edge of the channel after installation, affecting aesthetics; the channel lacks a pressure relief curb, leading to excessively fast rainwater flow and high kinetic energy, which can easily erode and damage surrounding buildings.
[0004] To this end, the inventors conducted beneficial explorations and attempts, and found a solution to the above problems. The solution to be introduced below was developed under this background. Utility Model Content
[0005] The technical problem to be solved by this utility model is to provide a fiberglass rapid flow channel with a pressure relief sill to address the shortcomings and defects of the existing technology.
[0006] The technical problem solved by this utility model can be achieved by the following technical solution:
[0007] A fiberglass trough with a pressure-relief curb includes an inlet groove and a trough body. The inlet groove has one end as a curbstone inlet and the other end as a trough inlet. The trough inlet is generally U-shaped, while the curbstone inlet is flared. The angle between the trough inlet and the curbstone inlet is 120-160 degrees. The trough body is also generally U-shaped. The trough bodies are connected by overlapping joints. A pressure-relief curb is provided at the bottom of the trough body.
[0008] In a preferred embodiment of this utility model, the stress relief sill is arranged perpendicular to the length direction of the rapid flow channel, and the cross-section of the stress relief sill is square or arc-shaped, with a height of 40mm and a width of 55mm.
[0009] In a preferred embodiment of this utility model, the top opening of the inlet groove and the rapid flow groove is bent outward to form a groove wing plate. The groove wing plate is provided with multiple sets of concave anchor bolt holes. The concave anchor bolt holes are adapted to cross-reinforced anchor bolts, and the anchor bolt caps are flush with the outer edge of the groove wing plate.
[0010] In a preferred embodiment of the present invention, the curbstone access end of the access groove is adapted to the road curbstone and its bottom surface is 1cm lower than the asphalt surface layer, and the overlap length of the adjacent rapid flow channel is 10cm and adopts the top-down overlap method.
[0011] In a preferred embodiment of this utility model, the rapid flow channel body is fixed at the overlap by a cross-shaped reinforced anchor rod.
[0012] In a preferred embodiment of this utility model, the surface of the rapid flow channel is provided with a water flow direction arrow.
[0013] In a preferred embodiment of this utility model, the inlet groove, the rapid flow groove body, and the stress relief sill are all made of SMC sheet glass fiber through high temperature pressing.
[0014] Due to the adoption of the above technical solution, the beneficial effects of this utility model are as follows:
[0015] In this embodiment of the utility model, an arc-shaped energy dissipation sill is added to the bottom of the rapid flow channel, which can effectively slow down the water flow speed and consume the kinetic energy of the water flow, avoiding erosion of downstream buildings or slopes due to excessive flow speed, and solving the problem of damage to surrounding facilities caused by excessive kinetic energy in traditional rapid flow channels.
[0016] In this embodiment of the utility model, the surface of the rapid flow channel is provided with a water flow direction arrow, which can intuitively indicate the installation direction, avoid reverse installation caused by human judgment errors, and greatly improve construction efficiency; at the same time, the overlapping method of the inlet channel and the rapid flow channel and the concave anchor hole design ensure rapid positioning and stable connection during the installation process.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the utility model will be further described below.
[0022] Please see Figure 1-3 As shown, this utility model discloses a fiberglass trough with a stress-relief sill. The inlet groove 10 and the trough body 40 are precisely shaped using a mold, while reserving space for the concave anchor bolt hole 50. The inlet groove 10, the trough body 40, and the stress-relief sill 70 are all made of SMC sheet glass fiber through high-temperature pressing. This material not only has high strength but also adapts well to various outdoor environments. During the pressing process, it is essential to ensure a tight connection between all structural components, especially the connection between the stress-relief sill and the trough body, which must be firm and reliable.
[0023] In this embodiment of the utility model, one end of the access groove 10 is a curbstone access end 20, and the other end is a rapid flow groove access end 30. The curbstone access end 20 is generally shaped like a figure-eight trumpet, and the rapid flow groove access end 30 is shaped like a U-bend. The angle between the rapid flow groove access end 30 and the curbstone access end 20 is 120 degrees to 160 degrees, and it is seamlessly connected to the curbstone, allowing rainwater to flow smoothly into the groove. The top opening of the groove wall extends outward to form a pair of access groove wing plates 11. Multiple sets of recessed anchor bolt holes are provided on the access groove wing plates 11, and the hole openings are flush with the outer edge of the access groove wing plates 11. At the same time, the outer edge of the multiple sets of recessed anchor bolt holes extends along the bottom of the groove wing plates to form an arc-shaped reinforcing rib structure 12.
[0024] In this embodiment of the invention, the rapid flow channel 40 has an overall elongated concave channel structure, resembling a longitudinally extending "U"-shaped channel, providing directional guidance space for water flow. The depth of the inlet of the rapid flow channel 40 is designed to be 20cm instead of the original 9cm, reducing the risk of water overflowing from the inlet. The two side walls of the rapid flow channel 40 are relatively regular, gradually widening from bottom to top, forming a stable channel boundary. Its bottom is flat or has a slope adapted to drainage needs, ensuring smooth water flow. The opening at the top of its channel wall also bends outward to form a pair of rapid flow channel wing plates 41, with multiple sets of concave anchor holes 50 distributed on the wing plates 41.
[0025] After production is completed, the installation phase begins, starting with the installation of the inlet trough 10. The curbstone inlet 20 of the inlet trough is adapted to the road curbstone, and its bottom surface 21 should be 1cm lower than the asphalt surface layer. This ensures better connection with the road surface and prevents rainwater leakage. Next, the connection between the inlet trough 10 and the trough body 40, as well as the connection between the trough body 40 and other troughs, is handled. They are fixedly connected by an overlapping method, with an overlap length of 10cm between adjacent troughs using an overlapping method. That is, the outer wall 40 of the previous trough body overlaps the inner wall 42 of the next trough body to be connected. It should be noted that the width of the outer wall 40 of the previous trough body is slightly narrower than the width of the inner wall 42 of the next trough body to be connected. Alternatively, a leak-proof structure can be formed by using an upper pressing and lower locking groove at the 40° overlap of the two rapid flow channels. This involves setting a raised locking strip on the bottom outer wall of the rapid flow channel and setting a concave strip-shaped locking groove on the bottom surface of the next rapid flow channel to be connected. A fixed elastic rubber strip is set inside the locking groove along the length of the groove. This overlapping method can effectively ensure the leak-proofness and stability of the connection.
[0026] For securing the components, the recessed anchor holes 50 on the inlet trough 10 and the rapid flow channel body 40 are fitted with cross-shaped reinforced anchor bolts 60, with the anchor bolt caps flush with the outer edge of the channel body. The inlet trough 10 and the rapid flow channel body 40 can also be secured at their joints using cross-shaped reinforced anchor bolts 60. The anchor bolts enhance the stability of the entire rapid flow channel structure, providing resistance to the impact of water flow.
[0027] In this embodiment of the invention, the bottom of the rapid flow channel is provided with a pressure relief sill 70. The pressure relief sill has a square or arc-shaped cross-section, with a height of 40mm and a width of 55mm. The arc-shaped pressure relief sill 70 can effectively slow down the water flow velocity, consume the kinetic energy of the water flow, and reduce the scouring of the downstream. At the same time, the bottom surface of the rapid flow channel 40 is recessed or protruding with a water flow direction arrow 80. The arrow clearly indicates the direction of the water flow, making it convenient for installers to quickly and accurately determine the installation direction, improving installation efficiency, and avoiding the impact on drainage effect due to incorrect installation direction.
[0028] The specific construction and installation process of this utility model embodiment is as follows:
[0029] I. Product Configuration and Selection
[0030] (a) Component composition
[0031] It consists of an inlet slot, a standard rapid flow channel body, a rapid flow channel body with a stress relief sill, and cross-shaped reinforced anchor bolts, and supports expansion and splicing as needed.
[0032] (II) Selection Parameters
[0033] Available colors include RAL2008 orange and 7042 traffic gray, suitable for different environmental signage needs; the default length of a single rapid flow channel is 1 meter, and for every additional meter, one additional rapid flow channel and two cross-shaped reinforced anchor rods are required.
[0034] II. Construction Process and Operating Standards
[0035] (a) Surveying and setting out
[0036] Core requirements: Based on the drawings, accurately locate the direction of the rapid flow channel, and the width of the line should be slightly smaller than the size of the rapid flow channel (leaving a 5-10mm allowance). Utilize the "narrow gap extrusion force" to enhance the friction between the rapid flow channel and the slope, ensuring that the installation is linear, straight, and accurately positioned.
[0037] (ii) Trench excavation
[0038] Process selection: manual excavation to avoid mechanical disturbance of the slope soil and ensure the stability of the structural foundation.
[0039] (III) Installation of Access Slot
[0040] Positioning and Connection:
[0041] The funnel-shaped opening at the inlet of the ditch is embedded in the curbstone, with the bottom surface 1cm lower than the asphalt surface layer. The lower opening points towards the toe of the slope along the ditch, and the tilt angle is adjusted according to the slope.
[0042] The junction with the curbstone uses an "embedded seal" to ensure that rainwater does not leak in.
[0043] Anchoring and seepage prevention:
[0044] Four cross-shaped reinforcing anchors are symmetrically arranged and driven into the slope using the "hammer-driven symmetrical hole" technique.
[0045] Gap treatment: Fill and compact the gaps between the bottom of the inlet groove, the flared end and the curb with cement mortar to form a "rigid anti-seepage layer" to prevent water seepage.
[0046] (iv) Installation of rapid flow channels
[0047] Section 1 Rapid Flow Channel (Initial Section)
[0048] Overlap requirements: The upper opening of the rapid flow channel and the lower opening of the inlet channel should overlap with the upper opening, with an overlap length of ≥10cm. The arrow on the bottom of the channel (pointing to the lower opening of the rapid flow channel) should be consistent with the direction of water flow to ensure that there is no reverse installation.
[0049] Anchoring and fixing: Two cross-shaped reinforced anchor rods are symmetrically arranged on the upper part of the rapid flow channel and driven into the slope to form an "initial anchoring system" with the anchor rods of the access channel.
[0050] Intermediate section rapid flow channel (Section 2 - Section N)
[0051] General standard: The upper opening of each section of the rapid flow channel overlaps the lower opening of the previous section with an "upper pressing down" joint, with a length of 10cm. The arrows on the bottom of the channel continuously point to the foot of the slope, forming a "flow guiding channel".
[0052] Anchoring rules: Two cross-shaped reinforcing anchors are symmetrically arranged at the joint, and the spacing between the anchors is adapted to the width of the trench to ensure the connection rigidity of the trench.
[0053] The final rapid flow channel (terminal section)
[0054] Terminal anchoring: After the overlap, two cross-shaped reinforced anchors are symmetrically arranged at the bottom of the rapid flow channel to resist the impact force at the end of the water flow.
