Description

Technical Field

[0001] This utility model relates to the field of roadbed drainage, and specifically discloses a prefabricated roadbed drainage ditch. Background Technology

[0002] Side ditches are longitudinal artificial ditches set on the outer side of the shoulder of cut roadbeds and the outer side of the foot of low fill roadbeds. They are used to collect surface water on the road surface, drain slope water intercepted by the roadbed on the slope above the road, quickly collect it and introduce it into a smooth drainage channel, and discharge it under the road through bridges and culverts.

[0003] With the vigorous construction of highway projects in my country, improving project quality, reducing labor costs, and accelerating construction speed have become inevitable trends. Prefabricated assembly technology is an effective way to solve these problems. Currently, roadbed drainage mostly adopts the method of cast-in-place concrete drainage ditches, which requires a lot of labor, has a long construction period, and relatively poor quality. Many drainage ditches develop defects such as deformation and damage after a few years of operation, resulting in high maintenance costs.

[0004] Existing prefabricated drainage ditches, due to their modular assembly method and lack of buffer structures, are prone to deformation after assembly, resulting in poor safety and short service life. Utility Model Content

[0005] This utility model proposes a prefabricated roadbed drainage ditch, which is easy to assemble quickly. The components are mutually restrained, making them less prone to deformation and ensuring the stability of the assembly. At the same time, it has a buffering effect, which improves the safety of the assembled drainage ditch and extends its service life.

[0006] This utility model is implemented as follows: a prefabricated roadbed drainage ditch includes a roadbed and a drainage ditch. The drainage ditch is equipped with bottom edge blocks and side edge blocks. The side edge blocks are arranged in groups, symmetrically and obliquely on both sides between two adjacent bottom edge blocks. Each bottom edge block includes a base and a dovetail block (larger at the top and smaller at the bottom). The base and dovetail block have the same width, and the top three-quarters of the base along its width is integrally formed with the bottom three-quarters of the dovetail block. A splicing block is located at the center of the end of the dovetail block extending beyond the base. A splicing groove adapted to the dovetail block is formed on the side of the dovetail block away from the splicing block. The lower end of each side edge block is engaged in a groove formed between the dovetail block and the base. Polygonal frames are provided on opposite sides of both left and right side edge blocks. Several equidistant protrusions are arranged along the length of the top of each dovetail block. A capping strip is provided on the top of two adjacent side edge blocks, with one side of the capping strip overlapping the roadbed. The top of the capping strip and the top of the roadbed are in the same plane.

[0007] Preferably, as an assembled roadbed drainage side ditch of the present utility model, a positioning groove is formed in the front end face of the rear side block along the height direction, and a positioning strip adapted to the positioning groove is provided on the rear end face of the front side block.

[0008] Preferably, as an assembled roadbed drainage side ditch of the present utility model, a "丄"-shaped guiding strip is provided at the bottom of the coping strip along the width direction, a guiding groove adapted to the guiding strip is formed in the top of the side block along the width direction, and the guiding strip is located in the guiding groove.

[0009] Preferably, as an assembled roadbed drainage side ditch of the present utility model, the joints between two adjacent swallowtail blocks, the joints between two adjacent side blocks, and the joints between two adjacent coping strips are respectively sealed with cement.

[0010] Preferably, as an assembled roadbed drainage side ditch of the present utility model, a drainage cover is provided above between the left and right side blocks, and a through groove with a width of one finger is formed in the top of the drainage cover along the length direction.

[0011] Preferably, as an assembled roadbed drainage side ditch of the present utility model, support blocks fixedly connected to the side blocks are provided on both sides below the drainage cover, and the support blocks are in a right-angled triangle shape.

[0012] Preferably, as an assembled roadbed drainage side ditch of the present utility model, the height of the drainage cover is slightly lower than the height of the coping strip.

[0013] The beneficial effects of the present utility model are:

[0014] In the present utility model, through the bottom block, the side block, and the coping strip, the assembly of the assembled roadbed drainage side ditch is simple and fast. After assembly, the assembled parts restrict each other pairwise, and are not easy to warp, misplace, separate, or deform, ensuring the stability of the assembly and shortening the construction period. At the same time, the side block is inclined, and the polygonal frame and convex ribs on the inner wall can buffer the internal water flow, reduce the scouring of the inside of the drainage groove, improve the safety of the assembled drainage groove, and extend the service life.

Specific embodiments

[0021] The present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments to help understand the content of the present utility model. The methods used in the present utility model are all conventional methods unless otherwise specified; the raw materials and devices used are all conventional commercially available products unless otherwise specified.

[0022] Please refer to Figure 1-4 A prefabricated roadbed drainage side ditch, comprising a roadbed 1 and a drainage trench 2. A bottom block 3 and side blocks 4 are assembled in the drainage trench 2. The side blocks 4 are symmetrically arranged in groups and obliquely on both sides between two adjacent bottom blocks 3. The bottom block 3 includes a base 5 and a swallowtail block 6 with a larger upper part and a smaller lower part. The base 5 and the swallowtail block 6 have the same width, and three-quarters of the top of the base 5 in the width direction is integrally formed with three-quarters of the bottom of the swallowtail block 6. At the center position of one end of the swallowtail block 6 that extends beyond the base 5, there is a splicing block 7. A splicing groove 8 adapted to the swallowtail block 6 is formed on one side of the swallowtail block 6 away from the splicing block 7. The lower end of the side block 4 is clamped in the clamping groove 9 formed between the swallowtail block 6 and the base 5, and polygonal frames 10 are provided on both opposite sides of the left and right side blocks 4. A number of equally spaced convex ribs 11 are arranged in the front and back in the length direction on the top of the swallowtail block 6. A coping strip 12 is provided on the top of the front and back adjacent side blocks 4, and one side of the coping strip 12 overlaps on the roadbed 1. The top of the coping strip 12 and the roadbed 1 are on the same plane. A "丄"-shaped guiding strip 15 is provided at the bottom of the coping strip 12 in the width direction. A guiding groove 16 adapted to the guiding strip 15 is formed in the width direction on the top of the side block 4, and the guiding strip 15 is located in the guiding groove 16. A positioning groove 13 is formed in the height direction on the front end face of the rear side block 4, and a positioning strip 14 adapted to the positioning groove 13 is provided on the rear end face of the front side block 4, and the positioning strip 14 is located in the positioning groove 13. The joints between two adjacent swallowtail blocks 6, the joints between two adjacent side blocks 4, and the joints between two adjacent coping strips 12 are respectively sealed with cement.

[0023] In this embodiment: the bottom edge blocks 3 are arranged sequentially at the bottom of the drainage ditch 2, with the rear bottom edge block 3 extending beyond the base 5 and overlapping the top of the base 5 located on the front bottom edge block 3. Simultaneously, the splicing block 7 on the rear bottom edge block 3 is fitted into the splicing groove 8 on the front and rear bottom edge blocks 3. The splicing block 7 and the splicing groove 8 serve as guides, facilitating quick assembly of the bottom edge blocks 3. After assembly, adjacent bottom edge blocks 3 are relatively constrained, preventing misalignment. The lower ends of the side edge blocks 4 on both sides are engaged in the slots 9 formed between the dovetail block 6 and the base 5, and the positioning strip 14 on one side edge block 4 is engaged in the positioning groove 13 on the other side edge block 4. Furthermore, one side edge block 4 spans two bottom edge blocks 3, and after assembly, the side edge block 4 aligns with the two bottom edge blocks. 3. Mutual restraint: The top strip 12 is placed on top of the two side blocks 4, and the guide strip 15 at the bottom of the top strip 12 is restricted by the guide groove 16, which can prevent the top strip 12 from tilting or misaligning, and make it easy and quick to assemble the top strip 12 onto the top of the side blocks 4. After assembly, the top strip 12 and the two side blocks 4 restrain each other, preventing them from separating at will and making them less prone to deformation, thus ensuring the stability of the assembly and shortening the construction cycle. Cement is used to seal the joints at the splicing gaps, which can prevent seepage in the drainage ditch 2. The polygonal frame 10 on one side of the side block 4 and the protruding ridge 11 on the top of the bottom block 3 can both buffer the water flow in the drainage ditch 2, reducing the scouring of the inside of the drainage ditch 2, improving the safety of assembling the drainage ditch 2, and extending its service life.

[0024] As a technical optimization of this utility model, a drainage cover 17 is provided above the two side blocks 4 on the left and right sides, and a through groove 18 with a width of one finger is opened on the top of the drainage cover 17 along the length direction.

[0025] In this embodiment, the through groove 18 on the drainage cover 17 serves as a guide. The drainage cover 17 can be set according to actual needs. For example, in a pedestrian crossing section, the drainage cover 17 can be attached to the assembled drainage ditch.

[0026] As a technical optimization of this utility model, the drainage cover 17 is provided with support blocks 19 on both sides below it and fixed to the side block 4. The support blocks 19 are in the shape of right triangles.

[0027] In this embodiment, the support block 19 supports the drainage cover 17, further improving the stability of the drainage cover 17.

[0028] As a technical optimization of this utility model, the top of the dovetail block 6 is provided with a number of equidistant ridges 11 arranged in the front and back along the length direction, and the ridges 11 are in the form of an upward convex arc-shaped strip structure.

[0029] In this embodiment, the arc-shaped strip structure can reduce the scouring of the bottom edge block 3 by the water flowing in the drainage ditch.

[0030] As a technical optimization of this utility model, the height of the drainage cover 17 is slightly lower than the height of the top bar 12.

[0031] In this embodiment, the height of the drainage cover 17 is slightly lower than the height of the capping strip 12, which further facilitates the collection of rainwater above the roadbed 1 into the drainage ditch through the drainage cover 17.

[0032] Working principle and usage process of this utility model:

[0033] The bottom edge blocks 3 are arranged sequentially at the bottom of the drainage ditch 2, with the rear bottom edge block 3 extending beyond the base 5 and overlapping the top of the base 5 located on the front bottom edge block 3. Simultaneously, the splicing block 7 on the rear bottom edge block 3 fits into the splicing groove 8 on the front and rear bottom edge blocks 3. After assembly, adjacent bottom edge blocks 3 are relatively restrained, preventing misalignment. The lower ends of the side edge blocks 4 on both sides are engaged in the slots 9 formed between the dovetail block 6 and the base 5, and the positioning strip 14 on one side edge block 4 is engaged in the positioning groove 13 on the other side edge block 4. Furthermore, one side edge block 4 spans two bottom edge blocks 3, ensuring that the side edge block 4 is aligned with both bottom edge blocks 3 after assembly. The bottom edge blocks 3 are mutually constrained, and the top strip 12 is placed on top of the two side edge blocks 4. After assembly, the top strip 12 and the two side edge blocks 4 are mutually constrained. After the whole assembly is completed, the adjacent parts will not separate at will, are not easily deformed, ensure the stability of the assembly, and have a short construction period. After assembly, cement is used to seal the joints to prevent seepage in the drainage ditch 2. The polygonal frame 10 on one side of the side edge block 4 and the protruding ridge 11 on the top of the bottom edge block 3 can both buffer the water flow in the drainage ditch 2, reduce the scouring of the inside of the drainage ditch 2, improve the safety of the assembled drainage ditch 2, and extend its service life.
