Supporting foundation reinforcing method for large-volume jacking engineering
The invention relates to a supporting foundation reinforcing method for a large-volume jacking project, which comprises a back wall and a raft, and comprises the following steps of: S101, arranging a combined reinforcing pile behind the back wall; s103, a plurality of steel sheet piles are driven behind the combined reinforcing piles, and foundation pit excavation is synchronously conducted in front of the back wall; after the step is finished, the step S105 and the step S109 are synchronously carried out; s105, a back wall combined grouting pipe is pre-buried in the back wall; s107, the soil body behind the back wall is subjected to grouting reinforcement; s109, a raft plate is constructed in front of the back wall, and a raft plate combined grouting pipe is pre-buried in the raft plate; and S111, the soil body at the bottom of the raft is subjected to grouting reinforcement. The reinforcing steel bars of the back wall and the raft plate are bound together to form a complete whole, and the raft plate and the back wall are reinforced respectively, so that the construction safety is ensured; due to the fact that the reinforcing structures of the raft and the back wall are located on the two sides of the back wall respectively, construction can be conducted at the same time, and construction time is saved.
本发明涉及一种用于大体积顶进工程的支撑基础加固方法，包括后背墙和筏板，包括以下步骤：步骤S101：在后背墙的后方设置组合加固桩；步骤S103：在组合加固桩的后方打设若干钢板桩，在后背墙的前方同步进行基坑开挖；本步骤结束之后，步骤S105、步骤S109同步进行；步骤S105：在后背墙内预埋后背墙组合注浆管；步骤S107：对后背墙后方的土体进行注浆加固；步骤S109：在后背墙的前方施工筏板，在筏板内预埋筏板组合注浆管；步骤S111：对筏板底部的土体进行注浆加固。后背墙与筏板的钢筋绑扎在一起，形成一个完整的整体，并分别对筏板和后背墙进行加固，保证施工安全；由于筏板与后背墙的加固结构分别位于后背墙的两侧，因此可同时进行施工，节约施工时间。
