Description

Technical Field

[0001] The utility model relates to the technical field of highway construction, in particular to a foldable temporary drainage trough for a roadbed. Background Art

[0002] Temporary drain chutes are essential drainage structures during highway subgrade construction. They serve as temporary drainage systems when water accumulates during rainfall. Typically, before permanent subgrade drainage is completed, several temporary drain chutes are installed at regular intervals along the subgrade slopes to drain rainwater away from the slopes. This is particularly true during highway subgrade construction in plain areas, where large volumes of fill and high fill heights can lead to significant surface water accumulation during the rainy season. This can easily erode the slopes and cause them to become unstable.

[0003] In the prior art, most of the drain troughs on the market are manufactured in one piece. During transportation or storage, the drain troughs need to be stacked. Stacking the drain troughs up and down will cause the drain trough below to deform, which will affect subsequent use. In addition, the existing drain troughs occupy a large space and a large storage space, which is not conducive to transportation and storage.

[0004] Chinese patent CN201920860683.6 discloses a "rapid flow trough for highway engineering," publication number CN210085979U. The device comprises a U-shaped trough with a hollow structure. The inner wall of the U-shaped trough is provided with a weighted filler groove. Cover plates are provided on the tops of both sides of the U-shaped trough, and a number of debris baffles are equidistantly provided at the ends of the two cover plates that are adjacent to each other. However, this device has some drawbacks: it cannot be folded, takes up a large amount of space, and is not conducive to transportation and storage. Utility Model Content

[0005] In order to solve the above problems of the prior art, the utility model provides a foldable temporary drainage chute for roadbed. The device can be folded and can be unfolded flat for easy transportation and storage.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a foldable temporary drainage trough for roadbed, comprising a plurality of trough bodies, wherein the trough bodies include a bottom plate, side plates symmetrically hinged on the bottom plate, and a fixing plate for connecting the side plates, wherein the side plates are parallel to the length direction of the bottom plate.

[0007] With the above structural design, when the device is stored, the side panels can be unfolded flat, which greatly reduces the space occupied by the tank body and makes it easier to stack the device, thereby facilitating transportation and storage.

[0008] Preferably, the side panels are hinged to the bottom panel via hinges, and a sealing strip is provided at the hinge between the side panels and the bottom panel.

[0009] With the above structural design, the hinges between the side panels and the bottom panel are sealed to prevent water leakage.

[0010] Preferably, a fixing pin is passed through the fixing plate, the upper end of the side plate is fixedly connected to the folding plate, and a plurality of mounting holes matching the fixing pin are provided on the folding plate.

[0011] With the above structural design, when the side panels are folded, the erected side panels are fixed, which has a simple structure and is quick to install.

[0012] Preferably, a plurality of ground nails are provided on the fixing plate, and the ground nails are of a spiral structure.

[0013] By adopting the above structural design, the device is fixed on the ground, which increases the stability of the device and prevents the trough body from deflecting under the action of external forces.

[0014] Preferably, both ends of the bottom plate are corrugated structures, and the corrugated structures are triangular corrugations, semicircular corrugations, or square corrugations.

[0015] With the above structural design, when the trough bodies are connected head to tail, the head end of the lower trough body can overlap and engage with the tail end of the upper trough body, thereby increasing the tightness of the connection.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1) When the device is stored, the side panels can be unfolded flat, greatly reducing the space occupied by the tank body, making it easier to stack the device for transportation and storage.

[0018] 2) The length of the device can be adjusted at any time according to the length of the slope, which can effectively save manpower and material resources and save construction costs.

[0019] 3) The device can be fixed on the ground to increase the stability of the device and prevent the trough from being deflected by external forces. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] See also Figure 1 、 Figure 2 、 Figure 3 The utility model provides a technical solution: a foldable temporary drainage trough for roadbed, comprising a plurality of trough bodies 1, wherein the trough body 1 comprises a bottom plate 11, side plates 12 symmetrically hinged on the bottom plate 11, and a fixing plate 13 for connecting the side plates 12, wherein the side plates 12 are parallel to the length direction of the bottom plate 11, and the side plates 12 and the bottom plate 11 together form a U-shaped trough structure.

[0024] The side panel 12 is hinged to the bottom panel 11 via a hinge 2. A sealing strip 3 is provided at the hinge between the side panel 12 and the bottom panel 11. The sealing strip 3 is fixedly connected at the edge of the side panel 12 or the bottom panel 11, or the edges of both the side panel 12 and the bottom panel 11 are fixedly connected to the sealing strip 3. The hinge 2 is provided below the sealing strip 3.

[0025] The fixing plate 13 is provided with a fixing pin 41 , the upper end of the side plate 12 is fixedly connected to the folding plate 4 , and the folding plate 4 is provided with a plurality of mounting holes 42 matching the fixing pin 41 , and the lower end of the fixing pin 41 is provided with an external thread.

[0026] A plurality of ground spikes 5 are passed through the fixing plate 13 , and the ground spikes 5 are of a spiral structure.

[0027] Both ends of the bottom plate 11 are corrugated structures, and the corrugated structures are triangular corrugations, semicircular corrugations, or square corrugations.

[0028] In order to facilitate the connection of the trough body 1, the opening at the front end of the trough body 1 should be slightly larger than the opening at the rear end. Accordingly, the corrugated structure should be able to facilitate the bottom plate at the upper end to be stacked on the bottom plate at the lower end, that is, the tail end of the upper trough body can be overlapped and clamped on the head end of the lower trough body.

[0029] In order to prevent fallen leaves or plastic bags from falling into the trough body due to bad weather and causing blockage of the trough body, the size of the slot formed in the trough body 1 matches the size of the fixing plate 13. The fixing plate 13 can cover the slot of the trough body 1, thereby preventing the trough body 1 from being blocked by foreign garbage.

[0030] When using this device:

[0031] The first step is to select the number of troughs 1 according to the length of the roadbed slope, and then overlap and clamp the tail end of the upper trough to the head end of the lower trough, and so on, to connect the troughs 1 end to end;

[0032] The second step is to install the fixing plate 13 at the connection of the tank body 1. The staff first folds the side plate 12 on one side, then uses the fixing pin 41 to pass through the fixing plate 13 and the mounting hole 42 on the folding plate 4, and then tightens it with a nut. Next, the staff performs the same operation on the side plate 12 on the other side.

[0033] In the third step, the staff drives the ground nails 5 into the ground to firmly fix the device on the ground, and the installation is completed;

[0034] In the fourth step, after the device is used, the fixing pin 41 and the nut are removed in sequence, and the unfolded trough bodies are stacked up and down for storage or transportation.
