TECHNICAL FIELD

[0001] The utility model relates to the technical field of concrete prefabricated component, and the specific field is a high anti-crack concrete prefabricated water interception ditch. BACKGROUND

[0002] As an important component of highway drainage system, the water interception ditch plays an important role in intercepting the slope water along the highway, reducing the burden of the side ditch, and protecting the slope foot and the side slope from being washed by water flow. Generally, the water interception ditch adopts a groove structure of bricklaying or concrete structure pouring, and a cover plate of metal or concrete structure with openings is covered on the groove structure. Rainwater flows into the water interception ditch through the cover plate with openings and then enters the highway drainage system through the water interception ditch. In some areas with abundant rainfall, especially in the rainy season, the amount of slope water along the highway is large, and debris on the mountain or roadbed is easily washed into the water interception ditch by the water flow. Large-volume debris is accumulated on the rainwater grate of the water interception ditch, which may cause the water flow to overflow to the road surface and affect the driving safety. SUMMARY

[0020] The specific implementation manners of the utility model are described in detail below in combination with the drawings, so that those skilled in the art can more clearly understand how to practice the utility model. Although the utility model is described in combination with its preferred specific implementation manners, these implementation manners are only illustrative but not limit the scope of the utility model.

[0021] Reference Figures 1-4In one embodiment of the utility model, a kind of high anti-crack concrete prefabricated water interception ditch is by the water interception ditch body 1 of multiple single structures head-to-tail connection composition ditch, single water interception ditch body 1 inside is also equipped with filter assembly 2, filter assembly 2 can follow the depth of water volume in water interception ditch body 1 up and down sink and float, for the water that enters water interception ditch is initially filtered, intercept larger volume of sundries;The top of single water interception ditch body 1 is also equipped with rainwater grate (not shown in drawing), for the water after the secondary filtration of filter assembly 2 is filtered.The water interception ditch of this utility model can be installed on both sides of highway, which can greatly improve drainage capacity and ensure driving safety.

[0022] The water interception ditch body 1 is a groove structure composed of a horizontally arranged bottom plate 12 and two vertically arranged side plates 11;the front end of the water interception ditch body 1 is provided with a male joint, and the rear end is provided with a female joint;the male joint and the female joint are matched with each other;when the water interception ditch is assembled, the male joint and the female joint between adjacent prefabricated monomers are embedded and closely attached to each other, which can improve the overall stability of the water interception ditch and enhance the waterproof effect;the top of the water interception ditch body 1 is provided with a placement step 15 for installing a rainwater grate.

[0023] The water interception ditch body 1 further includes a support plate 13, which is installed on the top of the side plate 11 away from the highway, and the support plate 13 is located on the right side of the bottom plate 12 in the embodiment. Figure 1 The support plate 13 is horizontally arranged, and the main end face of the support plate 13 is parallel to the main end face of the bottom plate 12;the support plate 13 is further provided with a square hole 14 extending longitudinally along the length direction of the support plate 13.

[0024] The filter assembly 2 includes a filter plate 21, a buoyancy piece 22, a limiting strip 23, and a plurality of nylon ties 24;the filter plate 21 is provided with a plurality of evenly arranged filter holes;the diameter of the filter holes is larger than the diameter of the rainwater grate;the buoyancy piece 22 is fixedly installed on the lower end of the filter plate 21 by the nylon ties 24;the length direction of the buoyancy piece 22 is consistent with the length direction of the filter plate 21;the limiting strip 23 is fixedly arranged on the upper end of the filter plate 21;in the implementation process, in order to facilitate installation, the limiting strip 23 and the filter plate 21 can be inserted or connected by screws;it should be noted that the buoyancy piece 22 is a tubular structure with both ends closed, and the hollow structure can generate a large buoyancy.

[0025] In the initial state, the upper end of the limiting strip 23 is flush with the upper end of the water interception ditch body 1, and the buoyancy piece 22 is slightly higher than the bottom plate 12;such arrangement can not only prevent the limiting strip 23 from blocking water when the water volume is small, but also avoid the buoyancy piece 22 from blocking the silt at the bottom of the water interception ditch, thereby ensuring normal water delivery of the water interception ditch when the water volume is small.

[0026] In one embodiment, the buoyancy piece 22 can also be a solid rod structure;at this time, the buoyancy piece 22 can be made of foamed plastic material.
