Foundation pit emergency rescue device and emergency rescue method thereof
The foundation pit emergency rescue device comprises supporting piles, a top beam, a supporting frame and a bearing frame, the supporting piles are arranged along the periphery of a foundation pit, a soil pit is excavated in a soil body on the outer sides of the supporting piles, the supporting frame is connected to the top beam in a buckled mode, the bearing frame is fixedly installed on the supporting frame, and the supporting frame and the bearing frame do not make contact with the bottom of the soil pit; and a soil body is filled in the bearing frame. The invention further discloses a construction method of the foundation pit emergency rescue device. The supporting frame is arranged on the top beam, and the bearing frame is installed on the supporting frame. The bearing frame is filled with the soil body with the corresponding size and weight, so that the bearing frame transmits the bending moment towards the outside of the foundation pit to the supporting pile through the supporting frame to reduce the excavation depth, and the bending moment towards the outside of the foundation pit generated by the supporting frame to the supporting pile can be adjusted by adjusting the weight of the soil body filled in the bearing frame; therefore, the anti-pressure capability of the support pile is improved.
本发明公开了一种基坑抢险装置，包括支护桩、冠梁、支撑架和承重框，支护桩沿着基坑外围设置，支护桩外侧的土体上开挖有土坑，支撑架扣接于冠梁上，承重框固定安装于支撑架上，且支撑架和承重框不与土坑的底部接触；承重框内填装有土体。本发明还公开了一种基坑抢险装置的施工方法。本发明采用在冠梁上设置支撑架，并在支撑架上安装承重框。通过在承重框中装填相应体积和重量的土体，使得承重框通过支撑架向支护桩传递向基坑外方向的弯矩，以减少开挖的深度，并且可以通过调节承重框内装填的土体的重量来调节支撑架对支护桩产生向基坑外的弯矩的大小，从而提高支护桩的抗压能力。
