Support dismounting and replacing construction process for foundation pit construction
The invention discloses a support dismounting and replacing construction process for foundation pit construction, and belongs to the technical field of support replacing construction, and the support dismounting and replacing construction process comprises the following steps: S1, after the bottom of a foundation pit is excavated, namely after the foundation pit is excavated to a preset foundation pit depth, constructing a structural bottom plate below a supporting beam at the bottommost layer, and ensuring that the structural bottom plate is always positioned below the supporting beam; s2, after the structural bottom plate reaches the strength required by design, a bottom temporary supporting structure used for supporting a bottom layer supporting beam is erected on the structural bottom plate, and it needs to be guaranteed that the top end of the bottom temporary supporting structure makes contact with the bottom of the supporting beam; s3, after the bottom temporary supporting structure is erected, a top temporary supporting structure is erected between the bottom layer supporting beam and the upper layer supporting beam; the supporting beams needing to be dismantled are connected with the supporting beams above the supporting beams, so that the supporting beams above the supporting beams can provide upward pulling force for the supporting beams, the bearing pressure of the disc buckle support can be reduced, the disc buckle support is prevented from being pressed to deform or collapse, and safety is improved.
本发明公开了一种用于基坑建设的拆撑换撑施工工艺，属于换撑施工技术领域，包括以下步骤：S1：基坑开挖见底后，即基坑开挖至预设的基坑深度后，在最底层支撑梁的下方对结构底板进行施工，需保证结构底板始终位于支撑梁的下方；S2：结构底板达到设计要求强度后，在结构底板上搭设用于支撑底层支撑梁的底部临时支护结构，且需要保证底部临时支护结构的顶端与支撑梁的底部接触；S3：底部临时支护结构搭设完成后，在底层支撑梁与其上方一层支撑梁之间搭设顶部临时支护结构；将需要拆除的支撑梁与其上方的支撑梁连接，使得其上方的支撑梁能够为其提供向上的拉力，能够减轻盘扣支架的承重压力，避免盘扣支架受压变形或倒塌，提高了安全性。
