Description

Technical Field

[0001] This utility model relates to a drainage ditch, specifically a drainage ditch for municipal roads, and belongs to the field of municipal engineering technology. Background Technology

[0002] Municipal road drainage ditches are facilities in municipal road drainage systems used to collect, transport, and discharge rainwater, snowmelt, and other wastewater from the road surface. They help protect the roadbed and pavement structure and extend the service life of the road. The structure of a drainage ditch mainly consists of an inlet, a ditch body, a cover plate, and inspection wells. The most common location for drainage ditches is on both sides of the road. They can effectively collect rainwater from the road surface and prevent rainwater from forming runoff on the road surface, which would affect driving safety. Traditionally, drainage ditches are installed by inserting two adjacent ditch bodies together. Before insertion, sealant is applied to the interface of one ditch body, and then the interface of the other ditch body is aligned and inserted. After insertion, another layer of sealant is applied at the connection between the two ditch bodies.

[0003] However, the process of applying sealant before splicing is relatively cumbersome, and the sealant requires a certain drying time, which makes the installation of the channel time-consuming and affects the installation progress. At the same time, it is difficult to accurately control the thickness and uniformity of the sealant. Uneven application of sealant will lead to poor sealing effect at the connection between adjacent channels, thereby increasing the risk of water leakage and affecting the stability of the drainage system. Furthermore, when water leakage occurs at the splice of two channels and repairs are needed, the old sealant at the splice must be removed and reapplied, which is troublesome and difficult to clean thoroughly. Utility Model Content

[0004] The purpose of this utility model is to provide a drainage ditch for municipal roads in order to solve the above-mentioned problems. The setting of the tenon and fixing component makes the adjacent ditch body form a tight sealing structure, effectively preventing water leakage, increasing the stability of the joint between the two ditch bodies, and making the installation and maintenance of the ditch body more convenient.

[0005] This utility model achieves the above-mentioned objectives through the following technical solution: a drainage ditch for municipal roads, comprising multiple ditch bodies, one end of each ditch body having a receiving slot, and the other end of each ditch body having a tenon fixedly connected thereto. The receiving slot of each ditch body is inserted into the tenon of an adjacent ditch body. A fixing component is installed at the insertion point of the receiving slot and the tenon.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-6 As shown, a municipal road drainage ditch includes multiple ditch bodies 1. One end of each ditch body 1 has a receiving slot 2, and the other end of each ditch body 1 is fixedly connected to a tenon 3. The receiving slot 2 of each ditch body 1 is inserted into the tenon 3 of an adjacent ditch body 1. A fixing component 4 is installed at the insertion point between the receiving slot 2 and the tenon 3. The fixing component 4 includes a groove 402, which is formed on the ditch body 1 and communicates with the receiving slot 2. A sealing strip 403 is installed on the outer wall of the tenon 3. The sealing strip 403 engages with the groove 402. The tenon 3 has an installation groove 404. A pressure plate 405 is slidably connected in the installation groove 404. Both ends of the pressure plate 405 are equipped with screws 406. The screws 406 are slidably connected to the tenon 3. The channel body 1 has two screw holes 407 at one end of the receiving slot 2. The bottom end of the screw 406 is threaded into the screw holes 407. A cover plate 7 is installed at the top of the channel body 1. A filter screen 5 is installed on the cover plate 7 through the installation assembly 6.

[0023] As a technical optimization of this utility model, a positioning hole 401 is provided on the channel body 1, and a positioning post 409 is fixedly connected to the bottom end of the tenon 3. The positioning post 409 is inserted into the positioning hole 401. By inserting the positioning post 409 into the positioning hole 401, the tenon 3 is quickly positioned, thereby preventing the tenon 3 and the channel body 1 from shifting laterally. The cross-section of the top of the tenon 3 is "L" shaped, and the cross-section of the sealing strip 403 is "U" shaped, which allows the sealing strip 403 to fit tightly against the inner wall of the channel body 1, thereby increasing the sealing performance at the joint of the two channel bodies 1. A sealing gasket 408 is fixedly connected to the end of the tenon 3. The sealing gasket 408 abuts against the end of the adjacent channel body 1. When the tenon 3 is inserted into the socket 2, the tenon 3 drives the sealing gasket 408 to abut against the end of the adjacent channel body 1, further enhancing the sealing effect and effectively preventing leakage.

[0024] As a technical optimization of this utility model, the installation component 6 includes a connecting strip 601. The connecting strip 601 is fixedly connected to both sides of the filter screen 5. The inner wall of the cover plate 7 has two sliding grooves 602. The connecting strip 601 is slidably connected to the sliding grooves 602. By pushing the connecting strips 601 on both sides of the filter screen 5 into the sliding grooves 602 on the cover plate 7, the cover plate 7 is quickly connected to the filter screen 5. The cross-section of the cover plate 7 is U-shaped, and the cross-section of the connecting strip 601 is trapezoidal, which guides the movement of the connecting strip 601, making it more convenient and flexible for the connecting strip 601 to slide in the sliding groove 602.

[0025] As a technical optimization of this utility model, the bottom end of the filter screen 5 is fixedly connected with two sets of positioning rods 603, and the top end of the channel body 1 is provided with two sets of positioning grooves 604. The positioning rods 603 are inserted into the positioning grooves 604, and the filter screen 5 drives the positioning rods 603 to be inserted into the positioning grooves 604 on the top of the channel body 1, thereby positioning the filter screen 5 and the cover plate 7 and preventing the filter screen 5 and the cover plate 7 from moving laterally.

[0026] As a technical optimization of this utility model, the cover plate 7 is provided with two sets of drainage grooves 8. The cooperation between the filter screen 5 and the drainage grooves 8 on the cover plate 7 can realize the orderly flow and efficient discharge of rainwater, while effectively intercepting and filtering impurities such as leaves on the road. The outer wall of the channel body 1 is fixedly connected with reinforcing ribs 9, and the setting of reinforcing ribs 9 increases the strength and stability of the channel body 1.

[0027] In use, when connecting two adjacent channel bodies 1, the end of one channel body 1 with the tenon 3 is aligned with the receiving slot 2 of the adjacent channel body 1. Then, the tenon 3 is pushed downwards to insert it into the receiving slot 2. During this process, the sealing strip 403 on the outer wall of the tenon 3 is driven to embed into the groove 402, forming a tight sealing structure to prevent water leakage at the joint of the two adjacent channel bodies 1. At the same time, the sealing gasket 408 at the end of the tenon 3 abuts against the end of the adjacent channel body 1, further enhancing the sealing and buffering effect. The tenon 3 is continuously pressed downwards until the positioning post 409 at the bottom of the tenon 3 is inserted into the positioning hole 401 of the adjacent channel body 1. The positioning post 409 and the positioning hole 401 are then used to accurately position and prevent the channel body 1 from shifting laterally. When installing the filter screen 5 on the cover plate 7, the connecting strips 601 on both sides of the filter screen 5 are aligned with the sliding groove 602 on the inner wall of the cover plate 7. Then, the filter screen 5 is pushed towards the cover plate 7. The filter screen 5 drives the connecting strips 601 to slide on the sliding groove 602. The filter screen 5 is quickly fixed to the cover plate 7 by the sliding engagement of the connecting strip 601 and the sliding groove 602, making the installation and removal of the filter screen 5 convenient. Next, the cover plate 7 is installed on the channel body 1. During operation, the positioning rod 603 at the bottom of the filter screen 5 is aligned with the positioning groove 604 at the top of the channel body 1, and the cover plate 7 is moved downwards so that the positioning rod 603 is inserted into the positioning groove 604. At the same time, the bottom ends of the filter screen 5 and the cover plate 7 come into contact with the channel body 1, thus quickly completing the installation of the filter screen 5 and the cover plate 7. The cover plate 7 is provided with a drainage groove 8. The cooperation between the filter screen 5 and the drainage groove 8 on the cover plate 7 plays a good guiding and filtering role in the drainage process. Next, the pressure plate 405 is placed into the mounting groove 404 of the tenon 3. Then, the screw 406 is passed through the pressure plate 405 and the tenon 3, and the bottom end of the screw 406 is screwed into the screw hole 407 on the channel body 1. By tightening the screw 406, the joint of two adjacent channels 1 is further fixed, thereby ensuring the stability of the connection between multiple channels 1.
