Embodiment Construction
[0025] Such as Figure 1~4 As shown, a hardening structure at the bottom of the drainage ditch includes a bottom hardening device, which is arranged at the bottom of the drainage ditch, and the bottom hardening device includes a T-shaped pile 1, a beam 2, a cover plate 3, and a T-shaped pile 1 Set at the bottom of the drainage ditch, completely inserted into the ground, the top surfaces of multiple T-shaped piles 1 are on the same level, and beams 2 are arranged on multiple T-shaped piles 1, and multiple cover plates are arranged on the beams 2 3.
[0026] The cover plate 3 is a cover plate with through holes.
[0027] Cement mortar is poured in the gap between the cover plate 3 and the slope body 4 .
[0028] Both ends of the bottom hardening device are provided with thrust piers 5 to prevent longitudinal displacement.
[0029] The lower part of the thrust pier 5 is made of masonry rubble, and the upper part of the thrust pier 5 is made of cast-in-place concrete.
