Description

Technical Field

[0001] The present invention relates to the technical field of building construction, and more specifically, to an assembled fiberglass flume structure and an installation method thereof. Background Art

[0002] Road ponding poses a serious threat to the stability of the road structure and driving safety. As an important part of the road drainage system, the flume is mainly used to collect the ponding on the road surface and quickly divert it to the roadside ditch of the road cutting, thereby effectively reducing the ponding on the slope, avoiding geological disasters such as slope instability, landslides or debris flows caused by long-term soaking, and at the same time reducing the scouring effect of the water flow on the slope and improving the drainage efficiency.

[0003] Traditional flumes mostly adopt masonry structures (such as concrete or grouted rubble stone), which have defects such as long construction period, high cost, and obvious restriction by climate conditions. In recent years, assembled fiberglass (FRP) flumes have emerged on the market. It consists of a receiving port and several precast flume sections. During installation, the elevation and plane position of each section need to be located first, then hoisted into place in sequence, and connected by flanges or lap joints. Finally, it is fixed to the foundation with anchor bolts.

[0004] However, the existing assembled fiberglass flumes still have the following technical problems: 1. The degree of fit between the flume body and the slope surface is insufficient. After long-term use, gaps are easily generated due to deformation, resulting in leakage or local ponding; 2. The anchoring method is limited, relying only on anchor bolts for fixation. The applicability of anchor bolts is restricted by the foundation material (such as soft soil, gravel, etc.), and the anchoring force provided by the sand cushion is weak, which is easy to cause the overall sliding of the flume body and affect the structural stability.

[0005] Based on the above technical defects, it is urgent to propose a new type of fiberglass flume structure and installation method to optimize the sealing performance, enhance the anchoring reliability, and improve the overall drainage performance. Summary of the Invention

[0006] Aiming at the deficiencies of the prior art, the purpose of the present invention is to provide an assembled fiberglass flume structure and an installation method thereof that can ensure a tight fit between the flume body and the slope surface.

[0007] The technical solution adopted by the present invention to solve its technical problems is: An assembled fiberglass flume structure includes a receiving port, which is in a trapezoidal groove structure. The large-mouth end of the receiving port is used to connect with the highway curb, and the small-mouth end is used to dock with the adjacent flume section. A number of flume sections are in a rectangular groove structure. Each flume section is connected in sequence. The frontmost flume section is connected to the small-mouth end of the receiving port, and the end of the rearmost flume section is used to connect with the drainage ditch. Connecting devices are arranged between the adjacent receiving port and flume section, and between adjacent flume sections, for realizing the connection between each section. A cement mortar layer is arranged on the lower side of the receiving port and flume sections. The receiving port and flume sections are fixedly connected to the foundation through the cement mortar layer.

[0008] As a preference, a further technical solution of the present invention is: Preferably, inner supports are arranged between the two side walls of the receiving port and flume sections.

[0009] Preferably, the inner support structure is an X-shaped cross support frame. The two ends are connected to the side wall of the receiving port or flume section through quick-release bolts, and the surface of the support frame is coated with an anti-corrosion coating.

[0010] Preferably, the connecting device includes a male hook and a female hook. The male hook is in a J-shaped structure. The female hook includes an outer wrapping part that fits the outer contour of the male hook and a hook connecting part that bends inward from the outer wrapping part and is clamped into the inner side of the male hook.

[0011] Preferably, rubber buffer cushion layers are arranged at the bottoms of the receiving port and flume sections.

[0012] The present invention also discloses an installation method for the assembled fiberglass flume, which is carried out by applying the assembled fiberglass flume structure. The specific steps are as follows: S1. Measurement and positioning: Use a total station to carry out axis lofting according to the design drawings to determine the center line and elevation control points of the flume. S2. Foundation trench construction: Excavate the foundation trench along the lofting axis. The bottom of the trench is tamped with a vibrating rammer to form a longitudinal drainage slope as required by the design. S3. Bedding laying: Lay a cement mortar bedding on the bottom of the foundation trench that has passed the acceptance. S4. Flume body assembly: Place the receiving port, and then connect each flume section in sequence from upstream to downstream behind the receiving port. S5. Mortar bedding and positioning: Press the assembled flume as a whole into the bedding so that the bottom of the flume body is fully in close contact with the mortar bedding. S6. Sealing treatment: The mortar extruded during pressing overflows along both sides of the flume body to form a sealing band. S7. Quality acceptance: Carry out a water passing test to check the leakage situation at the connection parts.

[0013] Preferably, in step S3, the thickness of the cement mortar bedding is 10 cm.

[0014] Preferably, in step S6, it further includes using a trowel to compact and smooth the overflow mortar and the slope surface.

[0015] The present invention adopting the above technical solution, compared with the prior art, its prominent features are: By setting the internal support structure and the cement mortar layer, the overall anti-deformation ability of the chute is improved, effectively solving the leakage problem caused by deformation of the traditional structure; the grouting method is used for construction, and through the double sealing structure of the bottom mortar cushion layer and the overflow sealing belt, the leakage rate of the chute during the later use process is reduced; at the same time, the grouting method construction breaks through the limitation of the foundation material, and the applicability under complex geological conditions such as soft soil and gravel is significantly improved.

In this embodiment, overhanging eaves 5 are provided on both sides of the receiving port 1 and the water trough section 2.

[0020] To prevent the cement mortar from squeezing the receiving port 1 and the side walls of the water trough section 2 during the bedding and positioning of the chute, causing deformation of the side walls, internal supports 4 are provided between the two side walls of the receiving port 1 and the water trough section 2. As Figure 3 , the internal support 4 can be of a straight structure; the internal support 4 can also be a support frame with an X-shaped cross structure, and both ends are connected to the side wall of the receiving port 1 or the water trough section 2 through quick-release bolts, and the surface of the support frame is coated with an anti-corrosion coating.

The female hook 302 includes an outer wrapping part that fits the outer contour of the male hook 301 and a hook part that bends inward from the outer wrapping part and is clamped into the inner side of the male hook 301.

[0022] Rubber buffer cushions are provided at the bottoms of both the receiving port 1 and the water trough section 2; through the elastic deformation of the rubber buffer cushions, local concentrated loads (such as the impact force brought by the rapid flow) can be dispersed, avoiding stress cracks at the bottom of the fiberglass tank body.

[0023] The present invention also discloses an installation method for an assembled fiberglass chute, which is carried out using the assembled fiberglass chute structure.
