Foundation pit excavation supporting method and structure considering space-time effect
The invention discloses a foundation pit excavation supporting method and structure considering the space-time effect, and relates to the technical field of foundation pit excavation supporting, and the concrete scheme is as follows: the foundation pit excavation supporting method considering the space-time effect comprises the following steps: a first supporting piece is clamped with an assembled Larsen sheet pile, and then sinks into the bottom of a foundation pit for a set depth along an excavation sideline of the foundation pit; a first layer of soil is excavated, second supporting pieces are fixedly connected with the large-diameter steel pipe piles within the excavation range of the foundation pit and then embedded into the bottom of the foundation pit by a set depth, and the first supporting pieces, the second supporting pieces and the large-diameter steel pipes are in one-to-one correspondence; steel coupling beams are arranged between the first supporting pieces and the second supporting pieces for fixing, surrounding purlins are arranged between every two adjacent first supporting pieces, a second layer of soil is excavated, and the steel coupling beams and the surrounding purlins are continuously arranged at set intervals; on the third layer, the first batch of soil is excavated in a spaced alternate bin sloping mode, a bottom plate and a force transmission belt are constructed to serve as a supporting structure to provide supporting force for supporting replacement, then the second batch of soil is excavated, and the remaining bottom plate is constructed.
本发明公开了一种考虑时空效应的基坑开挖支护方法及结构，涉及基坑开挖支护技术领域，具体方案如下：一种考虑时空效应的基坑开挖支护方法，包括第一支护件与拼装后的拉森板桩卡接后沿基坑开挖边线沉入基坑底设定深度；开挖第一层土，并在基坑开挖范围内将第二支护件与大直径钢管桩固定连接后嵌入基坑底设定深度，第一支护件、第二支护件、大直径钢管一一对应；第一支护件与第二支护件间设置钢连梁固定，相邻两第一支护件之间设置围檩，开挖第二层土，间隔设定距离继续设置钢连梁和围檩；第三层采用间隔跳仓放坡开挖第一批土并施工底板和传力带，作为支护结构提供换撑支撑力，之后开挖第二批土并施工剩余底板。
