Reinforced concrete retaining wall and variable cross-section special-shaped pile combined structure and construction method
The invention provides a reinforced concrete retaining wall and variable cross-section special-shaped pile combined structure and a construction method.The combined structure is arranged between a pre-pile-building structure and an unstable geologic body and comprises a reinforced concrete retaining wall, a top beam, a first special-shaped cross-section pile and a second special-shaped cross-section pile. The reinforced concrete retaining wall is arranged along the whole length of an unstable geologic body, the second special-shaped section pile, the first special-shaped section pile, the top beam and the reinforced concrete retaining wall are sequentially poured from bottom to top, and all parts of the combined structure are connected in an anchoring mode. A plurality of steps are excavated on the original slope surface of the unstable geologic body, and backfill soil is arranged between the plurality of steps and the combined structure. The section size of the pile body can be optimized under the condition that the use function of the support pile and the site safety are not changed, the requirement for the stability of a filling site is met, the use space of the top face of the structure and the safety of a pre-built structure of the structure are guaranteed, the construction cost is reduced, and comprehensive benefits are improved.
本发明提供了一种钢筋混凝土挡墙与变截面异形桩组合结构及施工方法，该组合结构设置于桩前建构筑物和不稳定地质体之间，包括钢筋混凝土挡墙、冠梁、第一异形截面桩、第二异形截面桩。钢筋混凝土挡土墙沿不稳定地质体通长布置，第二异形截面桩、第一异形截面桩、冠梁、钢筋混凝土挡墙自下而上依次浇筑，该组合结构各部分进行锚固连接；不稳定地质体的原始坡面上开挖多级台阶，多级台阶与该组合结构之间设回填土。本发明能够在不改变支护桩使用功能和场地安全的情况下，对桩身截面尺寸进行优化，不仅满足了填方场地稳定要求，确保结构顶面使用空间及结构前建构筑结构安全，而且降低了工程造价，提高了综合效益。
