RUAN CHENGFENG / FAN LI / NAN BO

The invention discloses a construction method for assisting in deep foundation pit excavation and brick blank membrane construction, and relates to the technical field of building construction. The construction method for assisting in deep foundation pit excavation and brick forming die construction comprises a brick forming die and comprises the following specific operation steps that S1, lofting is conducted according to the position and size of an elevator shaft and a water collecting well foundation pit in a design drawing, and an excavator is arranged to conduct excavation at a 60-degree slope; according to the construction method for assisting deep foundation pit excavation and brick blank film construction, the device is easy to manufacture, construction is rapid, installation is convenient, and the secondary cleaning cost caused by water accumulation and mud upwelling at the bottom of the foundation pit can be effectively avoided. Secondary rework caused by collapse of the side edge of the foundation pit due to mud alluviation can be effectively prevented, the construction period is shortened, the cost is saved, it is ensured that the base is dry during subsequent waterproof construction, and quality guarantee is provided for waterproof construction.

本发明公开了一种辅助深基坑开挖及砖胎膜施工的施工方法，涉及建筑施工技术领域。该辅助深基坑开挖及砖胎膜施工的施工方法，包括砖胎模，具体操作如下：S1、根据设计图纸中电梯井与集水井基坑位置尺寸进行放样，安排挖机以放坡60°进行开挖。该辅助深基坑开挖及砖胎膜施工的施工方法，装置制作简单，施工快捷，安装方便，可有效避免基坑底部积水和泥浆上涌而导致的二次清理费用。可有效防止因泥浆冲积而导致的基坑侧边塌陷而带来的二次返工，缩短工期、节约成本，且在后续防水施工时确保基底干燥为防水施工提供质量保证。
