[0008] Wherein, wing plates extending horizontally outward are respectively arranged on both sides of the top of the U-shaped groove, and the wing plates and the upper part of the groove wall of the U-shaped groove are perpendicular to each other.

[0009] One end of the U-shaped groove is provided with an inwardly concave tongue-and-groove groove, and the other end of the U-shaped groove is provided with an outwardly convex tongue-and-groove flange, and the tongue-and-groove flange of one U-shaped groove is embedded in the tongue-and-groove groove of the adjacent U-shaped groove.

[0010] Wherein, the width of the protrusion is equal to the width of the top opening of the U-shaped groove.

[0011] Wherein, a rubber sealing strip with an L-shaped longitudinal section is pasted on the end of the cover plate opposite to the extension pedal.

[0012] Wherein, the top end of the extension pedal is an inclined surface, and the top end of the extension pedal gradually increases from a side close to the cover plate to a side away from the cover plate.

[0013] Wherein, the longitudinal section of the water leakage hole is an inverted isosceles trapezoid.

[0014] The beneficial effects of the utility model are as follows: a U-shaped groove is used instead of cement mortar for base laying and bricks for ditch wall construction, a cover plate is used to cover the top of the U-shaped groove to prevent people from falling into the U-shaped groove, and an extension plate is used instead of paved pavement bricks for people to walk on; the drainage ditch structure adopts a modular design, and can be dry-constructed in a building block manner, without the need for cement mortar for bonding and fixing, so that the U-shaped groove and the cover plate can be reused.

[0021] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0022] like Figures 1 to 4 As shown, a drainage ditch structure of a construction site includes a U-shaped groove 1 and a cover plate 2. The U-shaped grooves 1 are placed in sequence in the grooves formed by excavation. Two adjacent U-shaped grooves 1 are connected by tongue-and-groove connection. The cover plate 2 is placed on the top of the U-shaped groove 1.

[0023] One end of the U-shaped groove 1 is provided with an inwardly concave tongue-and-groove groove 12 , and the other end of the U-shaped groove 1 is provided with an outwardly convex tongue-and-groove flange 13 . The tongue-and-groove flange 13 of one U-shaped groove 1 is embedded in the tongue-and-groove groove 12 of the adjacent U-shaped groove 1 .

[0024] A downwardly protruding bump 21 is provided at the bottom of the cover plate 2. The bump 21 is stuck in the top opening of the U-shaped groove 1. The width of the bump 21 is equal to the width of the top opening of the U-shaped groove 1. The bump 21 cooperates with the groove side wall to clamp the upper part of the groove wall of the U-shaped groove 1.

[0025] A plurality of leaking holes 22 penetrating vertically and evenly distributed are provided in the protrusion 21 and the cover plate 2 , and the longitudinal section of the leaking hole 22 is an inverted isosceles trapezoid.

[0026] An extension pedal 23 for people to walk on is provided on the side of the cover plate 2 close to the construction site. The top of the extension pedal 23 is an inclined surface, and the top of the extension pedal 23 gradually increases from the side close to the cover plate 2 to the side away from the cover plate 2.

[0027] Wing plates 11 extending horizontally outward are respectively arranged on both sides of the top of the U-shaped groove 1, and the wing plates 11 are perpendicular to the upper part of the groove wall of the U-shaped groove 1. The wing plates are used to increase the support area of ​​the top of the U-shaped groove 1 to prevent the U-shaped groove 1 from sinking in the groove.

[0028] A rubber sealing strip 3 with an L-shaped longitudinal section is pasted on the end of the cover plate 2 opposite to the extended pedal 23. During installation, the rubber sealing strip 3 is clamped between the cover plate and the concrete road cast along the periphery of the construction site to prevent water on the concrete road from flowing into the gap between the cover plate and the concrete road.
