Embodiment Construction
[0013] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0014] see figure 1 and figure 2 The structure of the prefabricated concrete half-culvert jet trough includes four parts: bottom fixed mortar 1, concrete prefabricated half-culvert pipe 2, large arc-shaped energy-dissipating steps 9, small-arc-shaped energy-dissipating steps 10, and two ditches 3 at the top. A concrete prefabricated half-culvert pipe 2 is arranged on the bottom fixed mortar 1, and a small arc-shaped energy-dissipating step 10 with an arc height of 40 mm to 60 mm is provided in the middle of the groove bottom of the single-section concrete prefabricated half-culvert pipe 2, preferably with a height of 50 mm. The joints of two concrete prefabricated half-culvert pipes 2 are provided with arc-shaped energy-dissipating steps 9 with an arc height of 180 mm to 220 mm. Bottom fixing mortar 1 adopts M7.5 cement mortar, width 4 shoul...
