Foundation pit support structure spanning existing building and construction method of foundation pit support structure
The invention relates to a foundation pit support structure crossing an existing building and a construction method thereof, and belongs to the field of open-cut foundation pit support structure construction. Fender posts are arranged on the two sides of the existing building, and pile top beams are arranged above the existing building and between the tops of the fender posts; reinforced concrete breast boards are connected between the pile top beams and the sides, close to the foundation pit, of the fender posts, and the fender posts play a role in supporting and stabilizing soil bodies around the foundation pit, so that the soil bodies are prevented from collapsing. The pile top beams are arranged at the top ends of the fender posts, the fender posts on the two sides of the existing building and on the periphery of the foundation pit are connected, and the stability of the whole enclosure structure is improved. The reinforced concrete breast boards are used for resisting lateral pressure of the soil body and underground water, preventing collapse of the soil body and permeation of the underground water, playing a role in supporting the soil body and ensuring the stability of the soil body around the foundation pit. According to the method, the existing structure does not need to be relocated or a post-construction structural form does not need to be changed, the stability of the existing structure is effectively protected, and the influence on the existing structure is reduced.
本发明的跨越既有构筑物的基坑围护结构及其施工方法属于明挖基坑围护结构施工领域，本发明在既有构筑物的两侧设置围护桩，在既有构筑物上方、围护桩的顶部之间设置桩顶冠梁，并在桩顶冠梁与围护桩的临基坑侧之间连接钢筋混凝土挡土板，其中围护桩起到支撑和稳定基坑周边土体的作用，防止土体坍塌。桩顶冠梁设置在围护桩的顶端，将既有构筑物两侧及基坑周边的围护桩连接起来，增加整个围护结构的稳定性。钢筋混凝土挡土板用于抵抗土体和地下水的侧向压力，防止土体坍塌和地下水的渗透，起到支撑土体的作用，保证基坑周边土体的稳定性。本发明不需要改迁既有构筑物或者改变后施工结构形式，有效地保护既有构筑物的稳定性，减少对既有构筑物的影响。
