The "horse path" in architecture refers to the ramp built inside the platform, which is generally symmetrical. The surface of the ramp is made of steep bricks, and the edges of the bricks form thick feet, commonly known as "chin", which is convenient for horses and vehicles to get on and off. In building construction, when the slope with a large angle is higher than a certain height, a horizontal road with a width of 1-2m is set on the slope.
According to Baidu Library, the "horse track" in water conservancy refers to the excavation of deep foundation pit foundation, transportation road or platform in cofferdam (which can also be interpreted as the transportation road or platform for excavation of slope), and a drainage ditch will be set on one side of the "horse track" for drainage. The drainage ditch beside the road is used to discharge the water filtered by the cofferdam. The function of the horse path is to intercept rainwater and prevent dam slope erosion; At the same time, it is also used for traffic and dam physical examination and observation; But also beneficial to that stability of dam slope.
The ancient "horse track" refers to the passage of riding into the city, and its main function is to transport soldiers, food and weapons.
