Construction method for foundation pit enclosure and earth excavation
The invention discloses a construction method for foundation pit enclosure and earth excavation. The construction method comprises the following steps of construction drawing design and drawing review, construction site preparation, support enclosure arrangement, drainage measure arrangement, earth excavation, cushion layer, bottom plate and force transmission belt pouring, support dismantling, basement structure construction completion, earth backfilling and grouting after pile pulling. Compared with the prior art, while the enclosure construction quality is emphasized, reasonable and reliable foundation reinforcement measures in the pit are adopted, and accumulated water in the foundation pit is pumped out in time, so that in the whole pit digging process, the foundation pit has better stability, meanwhile, excavation is performed in sequence in a segmented and layered mode from top to bottom, the gradient is reasonably controlled, slope toe cutting is avoided, side slope instability is prevented, and the safety is better.
一种基坑围护及土方开挖的施工方法，包括以下步骤：施工图纸设计及图纸会审，施工现场准备，设置支撑围护，设置排水措施，进行土方开挖，浇筑垫层、底板和传力带，拆除支撑，完成地下室结构施工，土方回填，拔桩后注浆；与现有技术相比，注重围护施工质量的同时，采用合理可靠的坑内地基加固措施，且及时抽去基坑积水，使得整体挖坑过程中，基坑具有更好的稳定性，同时开挖由上而下分段分层、依次进行，合理控制坡度，避免切割坡脚防治边坡失稳，具有更好的安全性。
