Shield-reserved penetration composite type foundation pit support wall and construction method thereof
The invention provides a shield-reserved penetration composite type foundation pit support wall and a construction method of the support wall. The support wall can effectively reduce the influence of construction of rail transit underground engineering in the front period on the later-period shield-reserved excavation construction. In order to solve the technical problem, the shield-reserved penetration composite type foundation pit support wall is characterized by comprising a short underground continuous wall and a stirring pile which is externally placed relative to the short underground continuous wall and used for reinforcing the continuous wall; structural steel is inserted in the stirring pile, and the short underground continuous wall is located above a shield-reserved penetration area; the position between the short underground continuous wall and the stirring pile is filled with a high-pressure rotary spraying pile, and the depth of the high-pressure rotary spraying pile exceeds that of the lower portion of the penetration area and meanwhile exceeds a shallow pressure bearing water layer, and the stirring pile is adopted by the support wall for internal reinforcing; and the position between an internal reinforced part and the short underground continuous wall is filled by a high-pressure rotary spraying pile.
