Deep foundation pit reinforcing method for strong permeable soft stratum
The invention relates to a deep foundation pit reinforcing method for a strong permeable soft stratum. The deep foundation pit reinforcing method comprises the following steps that S101, a reinforcement cage of a cast-in-place pile is prefabricated, and a plurality of reinforcing pieces are fixedly installed on the reinforcement cage of the cast-in-place pile at intervals; s103, pouring a cast-in-place pile: pouring concrete of the cast-in-place pile; and S105, grouting reinforcement is conducted, specifically, the soil body on the peripheral side of the cast-in-place pile is reinforced through a reinforcing piece. According to the reinforcing method, the cast-in-place piles are fully distributed in the foundation pit at intervals, the reinforcing pieces are embedded in the cast-in-place piles, the multiple reinforcing pieces are arranged, and the lengths of the reinforcing pieces are different, so that a grouting area is evenly distributed, soil around the foundation pit is evenly reinforced, the reinforcing effect is controllable, construction is easy and convenient, and overexcavation does not need to be conducted; the components and proportion of the slurry can be adjusted according to different stratum environments, so that the slurry is suitable for various stratum environments and various support forms, is high in applicability and has wide popularization and application values.
本发明涉及一种用于强透水软弱地层的深基坑加固方法，包括以下步骤：步骤S101、预制灌注桩的钢筋笼：在灌注桩的钢筋笼上间隔固定安装若干加固件；步骤S103、浇筑灌注桩：浇筑灌注桩的混凝土；步骤S105、灌浆加固：通过加固件对灌注桩周侧的土体进行加固。本加固方法在基坑内间隔满布灌注桩，灌注桩内预埋加固件，加固件设置有多个，且长度均不同，使得灌浆区域分布均匀，对基坑周围土体均匀加固，加固效果可控，施工简单方便，无需进行超挖；且可根据不同地层环境调整浆液成分、配比，适用于多种地层环境以及多种支护形式，适用性强，具有广泛推广应用的价值。
