Problems solved by technology

[0003] The above method has the following disadvantages: 1. Larger grading covers a large area and is not suitable for road sections with complex surrounding environments and many land use restrictions.
2. For deep and wide side ditches, the actual section size is much larger than the requirements of the water section, which not only increases unnecessary land occupation, but also causes waste of materials
3. Masonry and cast-in-place construction, the construction period is long and the quality is not easy to control

specific Embodiment

[0028] Specific examples: such as Figure 1-5 As shown, the main body 1 of the drainage side ditch has an overall size of 2000mm×650mm×1050mm, the cross-section of water is 0.29㎡, the size of the cover plate 2 is 740mm×640mm×50mm; 150mm×150mm, the detailed construction steps are as follows: (1) Prefabricate the side ditch according to the design length of the side ditch; (2) Excavate the pit body and make the foundation; (3) Install the main body 1, and paint waterproof adhesive material on the inside of the groove b , Lap tenon a and groove b sequentially; (4) install cover plate 2; (5) backfill soil on both sides of side ditch main body 1.

Abstract

The invention relates to a narrow-deep type prefabricated drainage gutter, which comprises a main body and a cover plate which are mutually connected, wherein the main body comprises a tenon which is arranged at one end, and the other end of the main body is provided with a groove which is in corresponding to the tenon of an adjacent gutter; a groove, in which a cover plate is embedded, is formed in the top of the main body; and beams are arranged at two ends of the top. Compared with the prior art, the prefabricated drainage gutter disclosed by the invention has the advantages of being small in occupied area, high in construction speed, capable of achieving self-sealing and self-cleaning effects and the like.

Description

technical field [0001] The invention relates to a side ditch, in particular to a narrow and deep prefabricated drainage side ditch. Background technique [0002] Side ditch refers to the ditches set up on both sides of the roadbed to collect and drain the running water of the road surface, road shoulder and slope. For roads located in plain areas that need to be provided with side ditches, due to the flat terrain, it is often difficult to find a suitable water outlet when designing the drainage system. Therefore, the distance between the water outlets is large and the drainage distance is long. There is a large difference between the elevation and the elevation of the road surface. The width-to-depth ratio of traditional gutters (external section width / external section depth) is relatively large, usually not less than 0.8. In order to meet the height difference requirements between the bottom of the ditch and the road surface, a shallow side ditch needs to be matched with ...
