Most of the canals in Xinjiang are built in the location of the mountain pass. The flood peak of the river is large in summer, carrying a lot of sediment and showing a short duration, and the scouring of the riverbed after the sluice gate is serious, threatening the stability of the gate chamber. In the engineering construction, the energy-saving and anti-shock treatment is mainly carried out in two types: sloped apron + deep partition wall and loped apron + apron board. In order to analyze the effect of these two types of energy dissipation, a comparative study was carried out through the hydraulic model test by choosing the Tarlang Canal Head Project. The experiment shows that the both kinds of energy dissipation work have good effect. The slope structure of the apron board can also cause the flood to produce partial reflux, which will bring the bed sediment back to the wall part, thereby reducing the scouring on the tooth wall. To this end, the experiment focuses on three kinds of structural sizes of skirt board elimination test. The test results show that the apron board energy dissipation type with the length of 6m is close to the erosion depth of the deep tooth wall energy dissipation type, and the depth is the shallowest. However, the position of the apron board crater is greater than that of the deep tooth wall. As a result, the apron board energy dissipation type can improve the safety performance of the tooth wall, while protecting the slope apron wall from being washed.
