Synchronous operation construction method for adjacent deep and shallow foundation pits
The invention discloses a synchronous operation construction method for adjacent deep and shallow foundation pits, which relates to the technical field of foundation pit support in constructional engineering, and comprises a deep foundation pit, a shallow foundation pit, a composite support structure, a movable pile body, a force transmission piece and a steel enclosing purlin. By arranging the fixed supporting piles and the slope structure, the structural strength, located on one side of the deep foundation pit, of the joint of the deep foundation pit and the shallow foundation pit is effectively enhanced, and by arranging the movable pile bodies and the force transmission pieces, balanced supporting force or pulling force can be applied to the two sides of the first vertical cast-in-place concrete piles; the structure stability of the junction of the deep foundation pit and the shallow foundation pit is guaranteed, meanwhile, the effect of further consolidating the soil body can be achieved, in addition, along with deep excavation of the soil body, the force transmission pieces are replaced in order to meet the force transmission requirements of the movable pile bodies at different depths, and therefore it can be guaranteed that in the whole construction process, the construction efficiency is improved. All the joints of the deep foundation pit and the shallow foundation pit are in a stable structure state, and finally, the movable pile bodies become fixed supporting pile bodies below foundation bottom plates of the deep foundation pit and the shallow foundation pit.
本发明公开一种相邻深浅基坑同步作业施工方法，涉及建筑工程基坑支护技术领域，包括深基坑、浅基坑、复合式支护结构、活动式桩体、传力件、钢围檩。本发明通过设置固定式支护桩及斜坡结构，有效加强了深基坑与浅基坑交接处位于深基坑一侧的结构强度，通过设置活动式桩体及传力件，可在第一竖向混凝土灌注桩两侧施加均衡的支撑力或拉力，保证深基坑与浅基坑交界处的结构稳定，同时，可起到对土体进一步巩固的效果，另外，随着土体的深挖，对传力件进行有序更换，以适应活动式桩体不同深度的传力要求，从而能够保证整个施工过程中，深基坑和浅基坑交接处全部处于结构稳定的状态，最后，活动式桩体成为深、浅基坑基础底板下方的固定式的支撑桩体。
