Description

Technical Field

[0001] This utility model relates to the field of drainage ditch technology, specifically to a prefabricated drainage ditch that is easy to install. Background Technology

[0002] A drainage ditch is a channel or trench used for drainage, typically to collect and discharge rainwater, groundwater, or other liquids to ensure unobstructed drainage systems around the ground or buildings and to prevent waterlogging or flooding. Drainage ditches are usually made of materials such as concrete, plastic, metal, or resin, and have a certain length and width, extending along the ground or surface to collect and guide water flow.

[0003] The existing technology disclosure number CN221167290U describes a prefabricated integrated drainage ditch with curb, in which multiple ditch module units are set at the edge of the road surface slab and arranged longitudinally along the road surface. Adjacent ditch module units are designed to be assembled and connected, and the top surface or the side surface of the top surface of the ditch module unit forms a grate structure. In this way, the functions of curb and road surface drainage are integrated, and can be adjusted according to the road surface drainage slope, rainwater runoff, and drainage method (single-sided drainage or double-sided drainage).

[0004] However, the two adjacent drainage modules are only bonded together with waterproof mortar. This means that after the drainage ditch is installed, the strength of some parts of the drainage ditch will be reduced due to oxidation after long-term use. It is also easily damaged by external factors such as cars, pedestrians, or impacts. This method of bonding with waterproof mortar means that it cannot be directly replaced. Instead, it can only be repaired by pouring cement and gravel and then allowing it to solidify, which is time-consuming and labor-intensive.

[0005] Therefore, there is a need for a prefabricated drainage ditch that is easy to install, in order to solve the problem of difficult maintenance of existing drainage ditch modules. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a prefabricated drainage ditch that is easy to install.

[0007] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a prefabricated drainage ditch that is easy to install includes a first connecting block and a second connecting block arranged alternately and connected. The upper ends of the first connecting block and the second connecting block are respectively provided with an inwardly recessed first drainage groove and a second drainage groove that extends through the front and rear. The inner wall of the front and rear openings of the first drainage groove is provided with an inwardly recessed abutment groove that extends through the front and rear. The side wall and bottom wall of the abutment groove are provided with a U-shaped sliding connection groove. The front and rear ends of the second connecting block are fixedly connected with a U-shaped protrusion that communicates with the second drainage groove, and the protrusion abuts against the inner wall of the abutment groove. The outer surface of the protrusion is fixedly connected with a U-shaped connecting protrusion that cooperates with the inner wall of the sliding connection groove. A sealing groove is provided on the outer surface of the protrusion away from the second connecting block and the connecting protrusion. The inner wall of the sealing groove is detachably connected with a sealing strip that abuts against the inner wall of the abutment groove. The sealing strip is made of elastic waterproof material.

[0008] By adopting the above technical solution, using the split first and second connecting blocks, two first connecting blocks can be placed in the ditch for the drainage ditch, and then a second connecting block can be placed between the two first connecting blocks from top to bottom. The connecting protrusion on the second connecting block slides into the sliding connecting groove on the first connecting block to complete the connection of the first and second connecting blocks. Before installation, a sealing strip needs to be placed in the abutment groove or sealing groove to ensure that water in the first and second drainage channels will not leak from the connection gap after the first and second connecting blocks are installed. This not only makes the installation of the drainage ditch convenient and quick, but also ensures the waterproof effect. Moreover, if a single first or second connecting block is damaged, the replacement and repair of the first and second connecting blocks can be completed simply by lifting the second connecting block upwards, greatly reducing maintenance costs.

[0009] The present invention is further configured such that: a first upper groove and a second upper groove are respectively provided at the opening positions of the first drainage groove and the second drainage groove, and when the first connecting block and the second connecting block are connected, the first upper groove and the second upper groove are connected, and the first drainage groove and the second drainage groove are connected. A plurality of drainage ditch cover plates are provided in the first upper groove and the second upper groove, which are distributed and abut against each other along the arrangement direction of the first connecting block and the second connecting block. A plurality of positioning blocks that are inserted into the sliding connecting groove are fixedly connected to the side of the drainage ditch cover plate.

[0010] By adopting the above technical solution, the positioning block with through holes can prevent pedestrians from tripping over the leaking first and second drainage channels. On the other hand, the positioning block can also perform preliminary filtration of the water flowing into the first and second connecting blocks, preventing large debris from falling directly into the first and second drainage channels and affecting the drainage effect. At the same time, the positioning block located on the side of the drainage ditch cover is engaged with the sliding connecting groove to complete the positioning of the drainage ditch cover in the front and rear direction of the first and second connecting blocks, preventing the drainage ditch cover from shifting during use and failing to cover the upper openings of the first and second connecting blocks.

[0011] The present invention is further configured such that there is a gap between the connecting protrusion and the sliding connecting groove, allowing the first connecting block and the second connecting block to swing.

[0012] By adopting the above technical solution, the gap between the connecting protrusion and the sliding connecting groove allows for a slight oscillation during the installation of the first and second connecting blocks, which can adapt to the ups and downs and left and right deflections of the site, thereby increasing the usability.

[0013] The present invention is further configured such that: the sealing strip is specifically made of elastic epoxy resin material, and its maximum thickness when naturally extended is greater than the distance between the sealing groove and the side wall of the abutment groove, and its minimum thickness under compressive deformation is less than the distance between the sealing groove and the side wall of the abutment groove.

[0014] By adopting the above technical solution, a sealing strip made of elastic epoxy resin material is placed in the sealing groove. When the second connecting block is installed, the sealing strip is inserted into the space between the sealing groove and the abutment groove as the second connecting block moves, and the gap is blocked to prevent water leakage in the first drainage groove and the second drainage groove, thereby increasing the drainage effect.

[0015] The present invention is further configured such that: the number of positioning blocks on one drainage ditch cover is four, and the four positioning blocks are distributed at the four corners of the drainage ditch cover and are respectively engaged with the positioning blocks on another drainage ditch cover in the same sliding connection groove.

[0016] By adopting the above technical solution, a sliding connection groove contains two different positioning blocks on the drainage ditch cover plates. The sliding connection grooves located at the four corners of the drainage ditch cover plates each contain positioning blocks on the drainage ditch cover plates. By utilizing the structure of several distributed positioning blocks that restrict the movement of the positioning blocks in the front, back, left, and right directions, the position restriction of the drainage ditch cover plates is further increased, thereby improving the installation effect.

[0017] In summary, this utility model has the following beneficial effects:

[0018] The first connecting block and the second connecting block are connected as one unit by using the connecting protrusion to slide into the sliding connecting groove. Then, the gap between the first connecting block and the second connecting block is blocked by the sealing strip located between the abutment groove and the sealing groove, ensuring that water will not leak into the first connecting block and the second connecting block. This not only improves the installation and maintenance of the drainage ditch, but also ensures that it has good waterproof and drainage effects. Attached Figure Description

[0027] The present invention will now be described in detail with reference to the accompanying drawings of the embodiments thereof. Example

[0028] This is a prefabricated drainage ditch that is easy to install, such as Figures 1 to 6As shown, the device includes alternating and connected first connecting blocks 11 and second connecting blocks 12. The upper ends of the first connecting blocks 11 and 12 are respectively provided with inwardly recessed first drainage grooves 13 and 20 extending through the front and rear. The inner wall of the front and rear openings of the first drainage groove 13 is provided with inwardly recessed abutment grooves 15 extending through the front and rear. The sidewalls and bottom walls of the abutment groove 15 are provided with U-shaped sliding connecting grooves 16. The front and rear ends of the second connecting block 12 are fixedly connected to U-shaped structures that communicate with the second drainage grooves 20. A protrusion 19 abuts against the inner wall of the abutment groove 15. A U-shaped connecting protrusion 17 is fixedly connected to the outer surface of the protrusion 19 and mates with the inner wall of the sliding connecting groove 16. A sealing groove 18 is formed on the outer surface of the protrusion 19 away from the second connecting block 12 and the connecting protrusion 17. A sealing strip 21 is detachably connected to the inner wall of the sealing groove 18 and abuts against the inner wall of the abutment groove 15. The sealing strip 21 is made of elastic waterproof material. A first upper groove 14 and a second upper groove 15 are respectively formed at the opening positions of the first drainage groove 13 and the second drainage groove 20. Upper groove 24, and when the first connecting block 11 and the second connecting block 12 are connected, the first upper groove 14 and the second upper groove 24 are connected, and the first drainage groove 13 and the second drainage groove 20 are connected. A plurality of drainage ditch cover plates 22 are provided in the first upper groove 14 and the second upper groove 24, distributed along the arrangement direction of the first connecting block 11 and the second connecting block 12 and abutting against each other. A plurality of positioning blocks 23 are fixedly connected to the side of the drainage ditch cover plate 22, which are inserted into the sliding connecting groove 16. There is a space between the connecting protrusion 17 and the sliding connecting groove 16 for the first connecting block 11 and... The gap of the swing of the second connecting block 12, the sealing strip 21 is specifically made of elastic epoxy resin material, and its maximum thickness when naturally extended is greater than the distance between the side wall of the sealing groove 18 and the abutment groove 15, and its minimum thickness under force compression deformation is less than the distance between the side wall of the sealing groove 18 and the abutment groove 15. There are four positioning blocks 23 on one drainage ditch cover plate 22, and the four positioning blocks 23 are distributed at the four corners of the drainage ditch cover plate 22 and respectively engage with the positioning block 23 on another drainage ditch cover plate 22 in the same sliding connecting groove 16.

[0029] First, place at least two first connecting blocks 11 in the already poured drainage ditch, ensuring the distance between the two first connecting blocks 11 is equal to the length of one second connecting block 12. Then, slide one second connecting block 12 from top to bottom into the space between the two first connecting blocks 11. Specifically, slide the connecting protrusion 17 from top to bottom into the sliding connecting groove 16, thus completing the connection between the first connecting blocks 11 and the second connecting block 12. Simultaneously, before installing the first connecting blocks 11 and the second connecting block 12, a sealing strip 21 made of elastic epoxy resin material can be directly wrapped around the sealing groove 18, or the sealing strip 21 can be directly adhered to the sealing groove 18 using glue or other methods. This allows the sealing strip 21 to slide synchronously into the abutment groove 15 during the connection of the first connecting blocks 11 and the second connecting block 12, sealing the connection point and preventing water from leaking out from the gaps. This facilitates installation while ensuring a good waterproof sealing effect. To enhance drainage, several drainage ditch covers 22 are inserted into the upper openings of the first upper groove 14 and the second upper groove 24. The side walls of the first upper groove 14 and the second upper groove 24 restrict the lateral movement of the drainage ditch covers 22. When the drainage ditch covers 22 are inserted into the first upper groove 14 and the second upper groove 24, the positioning blocks 23 on the side walls of the drainage ditch covers 22 simultaneously slide into the sliding connecting groove 16, further restricting the front-to-back movement of the drainage ditch covers 22. This completes the positioning and installation of the drainage ditch covers 22. When block 11 or the second connecting block 12 has a problem and needs to be repaired or replaced, first lift the drainage ditch cover 22 at the corresponding position upward and remove it, then lift the second connecting block 12 near the corresponding position upward, and then remove the first connecting block 11. This completes the disassembly of the first connecting block 11 or the second connecting block 12 at the corresponding damaged position. Then, put the replaced first connecting block 11 or the second connecting block 12 into the ditch. The order of placement is as follows: first put in the first connecting block 11, and then slide the second connecting block 12 into it from the top to complete the installation.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
