Construction method of muck pool with large-height-difference buttress retaining wall
The invention discloses a construction method of a muck pool with a large-height-difference buttress retaining wall. The construction method comprises the following steps that the buttress retaining wall which is vertically arranged is constructed on a structural top plate of an open excavation section tunnel behind an underground excavation section tunnel, the top of the buttress retaining wall is close to the ground, and the two sides of the buttress retaining wall are connected with enclosure structures on the two sides of the open excavation section tunnel correspondingly; performing waterproof construction on the top surface of the structural top plate and the wall back surface of the buttress retaining wall to form a waterproof structural layer; earthwork backfilling is conducted in the space defined by the enclosure structures on the two sides, the structural top plates and the buttress retaining walls to form a backfill soil layer; and a deslagging pool bottom plate and a buttress side wall are constructed on the top of the backfill soil layer, the buttress side wall is vertically arranged on the deslagging pool bottom plate in a supported mode, the buttress side wall and the buttress retaining wall are arranged in parallel in a spaced mode, and the two sides of the buttress side wall are further connected with enclosure structures on the two sides of the open excavation section tunnel correspondingly. According to the construction method, the technical problem of construction of the muck pool after tunnel excavation is solved, the capacity of the muck pool is larger than that of a muck pool constructed on a shortcut, and the muck pool does not occupy the shortcut.
本发明公开了一种具有大高差扶壁柱挡土墙的渣土池施工方法，包括以下步骤：在暗挖段隧道后方明挖段隧道的结构顶板上施工出竖直设置且顶部靠近地面并两侧分别与明挖段隧道两侧的围护结构连接的扶壁柱挡土墙；在结构顶板的顶面及扶壁柱挡土墙的墙背面进行防水施工以形成防水结构层；在由两侧的围护结构、结构顶板及扶壁柱挡土墙围设的空间内进行土方回填形成回填土层；在回填土层的顶部施工出渣池底板，及竖直支设于渣池底板上且与扶壁柱挡土墙平行间隔设置并两侧还分别与明挖段隧道两侧的围护结构连接的扶壁柱侧墙。本发明的施工方法土池，不仅解决了隧道开挖后方施工渣土池的技术问题，且渣土池容量比在便道上施工渣土池的容量大，且不占用便道。
