Description

Technical Field

[0001] This utility model belongs to the field of drainage guide channel technology, and specifically relates to a drainage guide channel structure. Background Technology

[0002] Drainage channels, also known as drainage ditches, are drainage systems commonly used on hardened surfaces such as streets and squares. They collect, drain, and collect rainwater through channels that are below ground level, allowing rainwater to be quickly drained from the ground during rainy days.

[0003] In the construction of some self-built facilities or later renovations, drainage channels are often constructed by trenching the ground, lining the trenches with bricks, and then covering them. This method is relatively easy to construct, offers a large adjustment range, and is highly flexible. However, during the trenching process, for aesthetic reasons or to avoid certain special terrain features, it is often necessary to create curved channels for turning and transition. The cover plates or gratings used for covering are usually square, and the arc length and the corresponding central angle of the prefabricated curved cover plates or gratings are relatively fixed. They cannot be adapted to the actual arc length or the corresponding central angle of the trench (i.e., the actual central angle may be too large or too small), meaning they cannot be well adapted and transitioned to the curved channel section. This necessitates workers to cut and process the cover plates on-site. On-site cutting and processing is unsafe and can easily lead to damage or scrapping of the cover plates, which is detrimental to practical use. Utility Model Content

[0004] The present invention aims to provide a drainage channel structure to solve the problem mentioned above that the prefabricated grating or cover plate cannot be well adapted to the actual arc-shaped channel.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a drainage guide channel structure, comprising...

[0006] The base has a hanging groove and a drainage groove on the top surface, both of which are arc-shaped in horizontal projection. The drainage groove is opened on the bottom surface of the hanging groove, and the projection of the drainage groove on the horizontal plane is located within the projection of the hanging groove on the horizontal plane.

[0007] The top plate assembly includes a cover plate and a transition plate installed in the mounting groove and arranged alternately. The cover plate has a square cross-section, and the transition plate has an isosceles trapezoidal cross-section. The side of the transition plate corresponding to the waist length abuts against the side of the cover plate, and the sides of the transition plate and the cover plate that abut against each other have the same length.

[0008] The principle and effects of this technical solution:

[0009] 1. By making the waist-length side of the transition plate the same as the side length of the abutting edge of the adjacent cover plate, it is easy to position and install the two cover plates on both sides of the transition plate. The isosceles trapezoidal structure of the transition plate facilitates the corner transition, allowing the arc-shaped drainage channel to be divided into multiple alternately distributed cover plates and transition plates. During this process, the straight sections of the cover plates and drainage channels can remain consistent. The number of transition plates can be increased or decreased according to actual use. Thus, through the setting of this top plate assembly, the device can achieve a better adaptation effect to on-site construction.

[0010] 2. The alternating distribution of isosceles trapezoidal transition plates and cover plates is more aesthetically pleasing than the later cutting of the cover plate, and the edges of the cover plate and transition plate are aligned, resulting in a less abrupt appearance and a stronger overall unity.

[0011] The present invention is further configured such that: limiting protrusions are fixed at both ends of the side wall of the transition plate, and limiting grooves are respectively opened on both sides of the bottom surface of the cover plate, and the limiting protrusions and limiting grooves are adapted to each other.

[0012] The principle and effect of this technical solution: By setting the limiting protrusion and limiting groove, the cover plate and the transition plate can be installed and positioned by the cooperation of the limiting protrusion and the limiting groove when they are spliced ​​together, so as to ensure the splicing accuracy of the cover plate and the transition plate. In addition, the limiting groove can also block the vertical direction of the limiting protrusion, thereby limiting the transition plate.

[0013] The present invention is further characterized by having positioning holes on the transition plate.

[0014] The principle and effect of this technical solution: The positioning hole allows the filter plate to be installed on the bottom surface of the mounting groove by fasteners passing through the positioning hole, thereby achieving the effect of positioning and limiting the position of the transition plate.

[0015] The present invention is further configured such that: a fixing layer and a water-permeable layer are provided in the hanging groove, the fixing layer abuts against the cover plate and the transition plate, the water-permeable layer is provided on the side of the fixing layer away from the cover plate, and a drainage hole is provided on the side wall of the drainage groove, the drainage hole extending to the water-permeable layer.

[0016] The principle and effect of this technical solution: By setting up a fixed layer, the horizontal direction of the top cover assembly can be restricted to ensure that the top cover assembly can be stably positioned above the drainage channel. Through the setting of the permeable layer and drainage holes, the water that has not been covered into the drainage channel can still enter the drainage channel through the permeable layer-drainage holes after reaching the permeable layer, thus improving the ability to treat the surrounding water.

[0017] The present invention is further configured such that: the bottom surface of the hanging groove has inclined sections on both sides, the projection of the inclined section on the horizontal plane coincides with the projection of the permeable layer on the horizontal plane, and the top edge height of the inclined section near the drainage groove is lower than the top edge height of the inclined section away from the drainage groove.

[0018] The principle and effect of this technical solution: The inclined section allows rainwater to enter the bottom of the hanging groove through the permeable layer and then spontaneously move closer to the side of the drainage groove, that is, closer to the drainage hole, and enter the drainage groove through the drainage hole. In other words, the inclined section makes it easier for water accumulated in the permeable layer to enter the drainage groove.

[0019] The present invention is further configured such that: a boss is fixed on the top surface of the mounting groove, a clearance groove is provided on the bottom surface of the cover plate, the clearance groove is adapted to the boss, an installation hole is provided on the boss, and a clearance hole corresponding to the installation hole is provided on the top surface of the cover plate.

[0020] The principle and effect of this technical solution: By setting the boss and the relief groove, the cover plate can be fitted onto the boss through the relief groove. The boss can limit the horizontal movement of the cover plate, thereby improving the stability of the cover plate relative to the mounting groove. Furthermore, by setting the mounting hole and the relief hole, the cover plate can be connected and fixed by bolts and fasteners passing through the relief hole and the mounting hole.

[0021] The present invention is further configured such that a support block is installed inside the drainage channel, and the top surface of the support block abuts against the cover plate and the transition plate.

[0022] The principle and effect of this technical solution: By setting up support blocks, when the width of the drainage channel is relatively wide, the bending moment force required to be borne by the middle of the cover plate and transition plate can be reduced by setting up intermediate supports, thereby improving the support strength of the top plate assembly.

[0032] Example:

[0033] As attached Figure 1-5 As shown, this utility model discloses a drainage channel structure, including a base 100 and a top plate assembly. The base 100 can be an existing concrete pavement or a pavement to be poured later. The top surface of the base 100 has a hanging groove 110 and a drainage channel 120, both with horizontal projections in the shape of arcs. (It also has a straight section, but the straight section is not the key improvement point of this solution. The straight section only needs to use a cover plate 210, and the cover plate 210 used for the straight section is completely consistent with the model and specifications of the cover plate 210 used for the arc section in this solution, so it will not be described in detail here.) The drainage channel 120 is opened on the bottom surface of the hanging groove 110, and the projection of the drainage channel 120 on the horizontal plane is located within the projection of the hanging groove 110 on the horizontal plane.

[0034] The top plate assembly includes a cover plate 210 and a transition plate 220 installed in the mounting groove 110 and arranged alternately. The cover plate 210 has a square cross-section (the horizontal cross-section is usually rectangular, also called a plate, and the top surface of the cover plate 210 has drainage holes / grooves, etc.). The transition plate 220 has an isosceles trapezoidal cross-section (the cross-section in the horizontal direction). The side of the transition plate 220 corresponding to the waist length abuts against the side of the cover plate 210, and the lengths of the sides of the transition plate 220 and the cover plate 210 that abut against each other are the same. In this solution, the included angle between the two sides of the transition plate 220 corresponding to the waist length and the longer bottom side of the transition plate 220 can be 80° or 82°. 5°, the length corresponding to the shorter bottom edge of the transition plate 220 should not be less than 100mm. Limiting protrusions 221 are fixed at both ends of the side wall of the transition plate 220. Limiting grooves 211 are opened on both sides of the bottom surface of the cover plate 210. The limiting protrusions 221 and the limiting grooves 211 are adapted to each other. Positioning holes 222 are opened on the transition plate 220. A boss 130 is also fixed on the top surface of the hanging groove 110. A clearance groove 212 is opened on the bottom surface of the cover plate 210. The clearance groove 212 is adapted to the boss 130. An installation hole is opened on the boss 130. A clearance hole corresponding to the installation hole is opened on the top surface of the cover plate 210.

[0035] A support block 140 is also installed inside the drainage channel 120. The top surface of the support block 140 abuts against the cover plate 210 and the transition plate 220.

[0036] The mounting groove 110 is further provided with a fixing layer 111 and a permeable layer 112. The fixing layer 111 abuts against the cover plate 210 and the transition plate 220. The permeable layer 112 is located on the side of the fixing layer 111 away from the cover plate 210. The side wall of the drainage trough 120 has drainage holes 121 that extend to the permeable layer 112. The bottom surface of the mounting groove has inclined sections 113 on both sides. The projection of the inclined section 113 on the horizontal plane coincides with the projection of the permeable layer 112 on the horizontal plane. The top edge height of the inclined section 113 near the drainage trough 120 is lower than the top edge height of the inclined section 113 away from the drainage trough 120. The fixing layer 111 is made of concrete, and the permeable layer 112 can be made of gravel or permeable concrete, etc.

[0037] In use, a drilling tool is used to drill a hole at an angle in the inclined section 113 until it connects with the drainage channel 120. Then, the arc-shaped section corresponding to the drainage channel 120 and the hanging groove 110 is installed, positioned, and adjusted so that the cover plate 210 and the transition plate 220 completely cover the arc-shaped section. Anchoring holes are made in the hanging groove 110 to position the boss 130 and the transition plate 220. Then, the cover plate 210 and the transition plate 220 are installed and fixed in the hanging groove 110 using fasteners. At this time, the pouring is carried out. The fixing layer 111 is constructed in a way that allows it to abut and limit the top plate assembly. During pouring, a release agent is applied to the outer edges of the cover plate 210 and the transition plate 220. Before the fixing layer 111 is completely solidified, the cover plate 210 and the transition plate 220 need to be demolded once to prevent the fixing layer 111 from sticking to the cover plate 210 and the transition plate 220. A permeable layer composed of permeable bricks or other permeable structures is set on the side of the fixing layer 111 away from the top plate assembly. The boss 130 is not required when the width of the drainage channel 120 is small.
