Penetration type skewback and foundation pit excavation method thereof
The invention discloses a penetration type skewback and a foundation pit excavation method thereof. The penetration type skewback comprises an upper side face and a lower side face which are opposite. The left side surface and the right side surface are opposite; the top surface and the bottom surface are opposite; the upper side surface is arc-shaped; the bottom surface is a stepped bottom surface; the lower side face, the left side face, the right side face and the top face are all planes, and the vertical face of the penetrating type skewback is obliquely arranged along the axis of an arch. According to the embodiment of the invention, the arch seats are arranged along the axial direction of the arch, so that the vertical force and the horizontal thrust transmitted by the arch rib are more directly and effectively borne; the layered step type foundation pit excavation method is adopted, and the problems that other skewback forms are large in construction difficulty, poor in construction safety, large in concrete use amount and large in soil excavation amount are solved.
本发明公开了一种贯入式拱座及其基坑开挖方法，该贯入式拱座包括：相对的上侧面和下侧面；相对的左侧面和右侧面；相对的顶面和底面；所述上侧面呈弧形；所述底面为台阶式底面；所述下侧面、所述左侧面、所述右侧面、所述顶面均为平面，所述贯入式拱座的立面顺接拱轴线倾斜布置。本发明实施例采用沿拱轴线方向布置拱座的方式，更为直接、有效地承担拱肋传递下来的竖向力和水平推力作用；采用的分层台阶式基坑开挖方法，解决了其它拱座形式存在的施工难度大、施工安全性差、混凝土用量大以及土体的开挖量大的问题。
