The invention discloses a vehicle passage foundation pit construction method which comprises the following steps: firstly, carrying out traffic conversion half-range traffic opening, and constructing a support pile after a foundation pit is excavated to the elevation of the top beam bottom of a pile foundation; the foundation pit is excavated downwards through a reverse construction method, and meanwhile an anchor lock structure is supported on the side wall; the foundation pit is downwards excavated to the foundation pit bottom elevation, and after the main body structure of the channel on the side is constructed, layered rolling and backfilling are conducted, and the road is recovered; and the steps are repeated to conduct foundation pit construction on the road on the other side. According to the vehicle passage foundation pit construction method, according to the traffic conversion requirement, a framing construction scheme is combined with a pile-anchor supporting mode to support the side wall, the problem that a slope cannot be made due to the fact that the construction occasion is limited is solved, zero-slope foundation pit excavation is achieved, and therefore the period needed by construction is shortened.
本申请公开一种车行地通道基坑施工方法，包括以下步骤：先进行交通转换半幅通车，待开挖基坑至桩基冠梁底标高后施作支护桩；采用逆作法下挖基坑，同时在侧壁支护锚锁结构；下挖基坑至基坑底标高，施工该侧通道的主体结构后，分层碾压回填并恢复道路；重复前述步骤对另一侧道路进行基坑施工。本申请使用的一种车行地通道基坑施工方法，根据交通转换要求，采用分幅施工方案结合桩锚支护的形式对侧壁进行支护，解决施工场合受限无法放坡的问题，做到零放坡开挖基坑，从而缩短施工所需的周期。
