Description

Technical Field

[0001] The invention relates to the technical field of road drainage, and in particular to an assembled roadbed intercepting ditch. Background Art

[0002] In roadbed projects, the application of prefabricated roadbed ditches is increasing. This technology mainly uses prefabricated components to assemble on site to achieve the purpose of rapid construction, reduce on-site workload and improve project quality. It has the advantages of high efficiency, high quality, flexibility and environmental protection.

[0003] When laying existing prefabricated roadbed intercepting ditches at the construction site, trenches are usually dug according to design requirements to ensure that the ditch bottom is flat and has a certain longitudinal slope for drainage. Then the prefabricated intercepting ditch components are laid in sequence from downstream to upstream. During laying, special connectors or caulking materials are used to firmly connect adjacent components to ensure that the interfaces are sealed and waterproof. After the components are installed, earth or other filling materials are backfilled in layers on both sides and the top according to regulations. However, only open interfaces or notches are usually opened on the intercepting ditch components. The connection strength between the two intercepting ditch components is low. When used for a long time or when the geology changes, the adjacent intercepting ditch components are prone to separation, thereby affecting the normal use of the intercepting ditch.

[0031] See also Figure 1-Figure 3 , an assembled roadbed intercepting ditch comprises: two slide rail devices 1 symmetrically distributed front and back, a plurality of water guiding devices 2 evenly distributed and interconnected are connected between the two slide rail devices 1.

[0032] See also Figure 1 , Figure 4 and Figure 5 The slide rail device 1 includes a rectangular frame slide rail 11, a plurality of evenly distributed support columns 13 are installed at the lower end of the rectangular frame slide rail 11, and a plurality of evenly distributed positioning holes 12 are opened on the upper frame wall of the rectangular frame slide rail 11.

[0033] During the specific work, two slide rail devices 1 and multiple water guiding devices 2 are transported to the laying position, and then the rectangular frame slide rail 11 is selected, and the two rectangular frame slide rails 11 are plugged and fixed in the ground at the laying position through multiple support columns 13.

[0035] See also Figure 4 and Figure 5 The water guide mechanism 21 includes a water guide frame 211 disposed between the two slide rail devices 1 , and the water guide frame 211 is a U-shaped structure with an opening facing upward.

[0036] See also Figure 4 , Figure 7 and Fig. 9 The sliding mechanism 22 includes a rectangular protrusion 221 integrally formed on the outer surface of the opening of the water guide frame 211, the rectangular protrusion 221 is located at the upper end of the rectangular frame slide rail 11, a downward pressing opening 222 is opened at the upper end of the rectangular protrusion 221, and a stepped circular hole 223 is opened on the bottom wall of the downward pressing opening 222, and a limiting rod 224 is inserted into the stepped circular hole 223.

[0037] During specific operation, the limit rod 224 and the stepped circular hole 223 are initially in a separated state. After the two rectangular frame slide rails 11 are fixed, multiple water guide frames 211 are placed between the two rectangular frame slide rails 11 in sequence. The water guide frame 211 drives the two rectangular protrusions 221 to be placed on the upper ends of the two rectangular frame slide rails 11. The rectangular protrusions 221 slide in cooperation with the rectangular frame slide rails 11. The multiple water guide frames 211 placed between the two rectangular frame slide rails 11 can be ensured to be at the same height, avoiding the unevenness of the paved ground from affecting the splicing of the multiple water guide frames 211.

[0038] See also Figure 6 , Figure 7 and Fig. 9 A U-shaped plug-in slot 212 is provided at one end of the water guide frame 211, and the plug-in slot 212 is plugged into the sealing mechanism 23. A U-shaped connecting protrusion 213 is integrally formed at the other end of the water guide frame 211. First limiting holes 214 connected to the plug-in slot 212 are provided on both end walls at the opening of the water guide frame 211, and second limiting holes 215 are provided on both end walls at the opening of the connecting protrusion 213.

[0039] See also Figure 5 , Figure 6 , Figure 7 and Fig. 9The connecting protrusion 213 of any water guide frame 211 is plugged into the adjacent plug-in groove 212 to enable multiple water guide mechanisms 21 to be spliced ​​with each other, multiple cover plates 241 cover the upper ends of multiple water guide frames 211, the first limiting hole 214 is aligned with the second limiting hole 215, and the two spliced ​​water guide mechanisms 21 are limitedly connected through the plug-in mechanism 242.

[0040] See also Figure 5 and Figure 6 The water guide mechanism 21 is connected to a sealing mechanism 23, and the sealing mechanism 23 includes a connecting frame 231 inserted into the plug-in groove 212. The connecting frame 231 is a U-shaped structure and has a U-shaped cross-section. A sealing rubber pad 232 is laid in the connecting frame 231. The sealing rubber pad 232 located on the outside of the connecting frame 231 is fitted with the end of the water guide frame 211 where the plug-in groove 212 is opened.

[0041] In specific operation, after a plurality of water guide frames 211 are placed between two rectangular frame slide rails 11, two adjacent water guide frames 211 are spliced ​​in sequence. During the splicing process of the two adjacent water guide frames 211, the connecting protrusion 213 of one water guide frame 211 is inserted into the plug-in groove 212 of the other water guide frame 211. When the connecting protrusion 213 cooperates with the plug-in groove 212, the connecting protrusion 213 moves into the corresponding connecting frame 231. The sealing rubber pad 232 in the connecting frame 231 increases the sealing between the connecting protrusion 213 and the connecting frame 231. As the connecting protrusion 213 moves, the two water guide frames 211 are pressed against each other and squeeze the sealing rubber pad 232 outside the connecting frame 231, effectively The recess at the end of the water guide frame 211 is filled, thereby increasing the sealing between the two water guide frames 211 and preventing water from flowing out of the gap between the two water guide frames 211. When the two water guide frames 211 are close to each other, the two second limiting holes 215 on the connecting protrusion 213 that cooperate with each other are coaxial with the two first limiting holes 214 connected to the plug-in groove 212. This step is then repeated until multiple water guide frames 211 are plugged into and matched with each other, and then multiple limiting rods 224 are respectively plugged into the corresponding stepped circular holes 223. The limiting rods 224 penetrate the stepped circular holes 223 and are plugged into and matched with the corresponding positioning holes 12, thereby realizing the function of limiting the rectangular protrusion 221, and then realizing the function of limiting the water guide frame 211.

[0042] See also Figure 1 , Figure 5 , Figure 7 and Fig. 9The water guide mechanism 21 is connected to a top cover mechanism 24, and the top cover mechanism 24 includes a cover plate 241 placed on the upper end of the water guide frame 211. Two plug-in mechanisms 242 are symmetrically connected to the cover plate 241, and the two plug-in mechanisms 242 are respectively connected to the two first limiting holes 214 on the water guide frame 211.

[0043] See also Figure 7 and Fig. 9 A rectangular notch communicating with the downward pressure opening 222 is provided in the middle of both ends of the opening of the water guide frame 211 , and a placement opening 2111 for placing the cover plate 241 is also provided at both ends of the opening of the water guide frame 211 .

[0044] See also Figure 7 and Fig. 9 The cover plate 241 is provided with a plurality of evenly distributed water leakage holes, and both the front and rear ends of the cover plate 241 are provided with positioning protrusions 2411 , and the positioning protrusions 2411 are slidably matched with the rectangular notch and the downward pressure opening 222 at the same time.

[0045] During specific operation, after multiple water guide frames 211 are spliced, multiple cover plates 241 are placed in the placement openings 2111 on the multiple water guide frames 211 in turn. When the cover plates 241 are placed, the two locking protrusions 2411 are driven to slide and cooperate with the two downward pressure openings 222, which not only guides the placement of the cover plates 241, but also limits the limiting rods 224 in the stepped circular holes 223 to prevent the water guide frames 211 from sliding. After the cover plates 241 cover the upper end of the water guide frames 211, the water inlet position of the water guide frames 211 is blocked to prevent branches, plastics and other garbage from entering the water guide frames 211.

[0046] See also Figure 7-Figure 9 The plug-in mechanism 242 includes a placement countersunk hole 2421 opened at the upper end of the cover plate 241, a limiting groove 2422 is opened on the annular hole wall of the placement countersunk hole 2421, and a placement notch is opened on the upper groove wall of the limiting groove 2422. A rotating column 2423 is rotatably connected in the placement countersunk hole 2421, and a limiting plate 2424 that slides with the limiting groove 2422 is installed on the annular surface of the rotating column 2423. A plug-in rod 2425 is installed at the lower end of the rotating column 2423, and the plug-in rod 2425 slides through the cover plate 241 and is plug-in-matched with the first limiting hole 214.

[0047] In specific operation, after the cover plate 241 is placed on the upper end of the water guide frame 211, the two rotating columns 2423 are moved to the top of the two placement countersunk holes 2421 of the cover plate 241, and the rotating columns 2423 are moved downward, and the rotating columns 2423 drive the limiting plate 2424 and the plug-in rod 2425 to move. The plug-in rod 2425 penetrates the cover plate 241 downward and is plugged and matched with the coaxial second limiting hole 215 and the first limiting hole 214 at the same time, thereby improving the connection strength between the connecting protrusion 213 and the plug-in groove 212, thereby improving the connection between the two water guide frames 211. The strength of the rotating column 2423 is achieved, and at the same time, the rotating column 2423 drives the limiting plate 2424 from the placement gap into the limiting groove 2422, and then the rotating column 2423 is rotated, and the rotating column 2423 drives the limiting plate 2424 away from the placement gap, and the limiting groove 2422 limits the limiting plate 2424 to prevent the rotating column 2423 from being separated from the placement countersunk hole 2421. After multiple rotating columns 2423 are connected to multiple cover plates 241, soil is backfilled to both sides of multiple water guide frames 211, and then fixed with concrete, and the installation of the assembled roadbed intercepting ditch is completed.
