Abstract
The invention discloses a supporting method and structure for a deep accumulation body slope. Two rows of round-section reinforced concrete piles which are arranged in a staggered manner are used as the main supporting structure for the deep accumulation body slope, the clear distance between the edges of the piles is controlled to be 10 cm or so, and the main supporting structure is mainly used for preventing water flow from washing and scouring the deep accumulation body slope. The pile tops of the round-section reinforced concrete piles are connected into a whole through a pile top concrete connection beam. The pile top concrete connection beam is integrally connected with a concrete fitting slope on the pile top concrete connection beam so that it can be ensured that the round-section reinforced concrete piles and the concrete fitting slope are integrally stressed. By means of the supporting method and structure, the round-section reinforced concrete piles are used as the main supporting structure for the deep accumulation body slope 1, mechanical hole forming is mainly adopted in construction, and the construction efficiency can be obviously improved; the construction difficulty and the safety risk in the construction period can be effectively lowered, and the guaranteed rate in the construction period is higher; and the purpose that the parts, between the piles, of the accumulation body slope are prevented from being washed by the water flow can be effectively achieved by reasonably designing the pile distance.
