Fabricated supporting system without inner support in large-area foundation pit and construction method of fabricated supporting system
The invention relates to an inner-support-free fabricated supporting system in a large-area foundation pit and a construction method thereof, the fabricated supporting system comprises a foundation pit support structural member, the top and waist of the foundation pit support structural member are respectively provided with a top beam and a purlin beam, and the outer side of the foundation pit is provided with fabricated prestressed anchoring parts; the inclined supporting piece is arranged on the inner side of a foundation pit of the enclosure structure, an included angle is formed between the inclined supporting piece and the enclosure structure, and the tops of the inclined supporting piece and the enclosure structure are connected; the inclined supporting pieces are arranged right opposite to the assembly type prestress anchoring pieces, and beam string structure pieces are arranged at the positions, between the adjacent inclined supporting pieces, of the top beam and the purlin beams respectively. Deformation of the foundation pit can be effectively controlled, a large number of inner supporting rod pieces are prevented from being used in the foundation pit, it is guaranteed that a large earth cutting space is formed in the foundation pit, and the technical effect that the whole foundation pit is detachable and reusable is achieved.
一种大面积基坑中无内撑的装配式支护体系及其施工方法，其中的装配式支护体系，包括：基坑围护结构件，所述基坑围护结构件的顶部和腰部分别设有冠梁及围檩梁，其基坑外侧设有装配式预应力锚固件；倾斜支撑件，所述倾斜支撑件设置在所述围护结构的基坑内侧，所述倾斜支撑件与所述围护结构呈夹角布置且顶部相连；所述倾斜支撑件与装配式预应力锚固件正对布置，所述冠梁及围檩梁上在相邻倾斜支撑件之间的位置均分别设有张弦梁结构件。本发明能够既有效控制基坑变形，又避免在基坑内使用大量内支撑杆件，保证基坑中具有较大的挖土空间，还实现了整体可拆卸、可复用的技术效果。
