Cross three-dimensional channel pre-reinforcing and holing construction method
The invention discloses a crossed three-dimensional channel pre-reinforcing and holing construction method, which relates to the field of building construction, and adopts the technical scheme that the method comprises the following steps: S1, reinforcing a soil body behind a pile; s2, a channel steel cross support is arranged above the pre-formed hole; s3, integrally reinforcing the pile body at the upper part of the hole; s4, breaking the hole; s5, the double-row steel beams of the cut pile body are transversely supported and reinforced; s6, steel stand columns are erected; s7, breaking the pile body; s8, backfilling is conducted; s9, upper layer communication construction; s10, cutting off and reinforcing the part, communicated with the connection port, of the pile body on the upper side; and S11, breaking the wall body. The construction method has the beneficial effects that the lower structure is constructed firstly and then the upper structure is constructed in a manner of'bottom-up '; firstly supporting and then dismantling are conducted, supporting is conducted firstly before dismantling, and then the piles are dismantled on the premise that safety is guaranteed; and reinforcing is conducted synchronously, after the pile foundation is dismantled, reinforcing is conducted at the same time, and construction safety is guaranteed.
本发明公开了一种交叉立体式通道预加固及开洞施工方法，涉及建筑施工领域，技术方案为，包括S1、桩后土体加固；S2、预开洞口上方设置槽钢交叉支撑；S3、洞口上部桩体整体加固；S4、洞口破除；S5、对已切除的桩体双排型钢梁横向支护加固；S6、支设钢立柱；S7、桩体破除；S8、回填；S9、上层连通施工；S10、上侧连通接驳口部分桩体切除并加固；S11、破除墙体。本发明的有益效果是：采用“先下后上”，先进行下层结构的施工，再进行上部结构施工；“先支后拆”，在拆除之前先进行支护，保证安全的前提下再进行桩的拆除；“加固同步”，在拆除桩基后，同时进行加固，保证施工安全。
