Foundation pit excavation method
The invention relates to a foundation pit excavation method. The method comprises the following steps that 1, a dewatering belt is arranged in a to-be-excavated foundation pit area, wherein the dewatering belt intersects with the seepage direction of underground water in the to-be-excavated foundation pit area, and underground water in a dewatering belt setting area through using the dewatering belt so as to block the underground water in front of the dewatering belt; 2, an area located at the downstream of the dewatering belt in the seepage direction of the underground water is excavated; 3,another dewatering belt on one side of the dewatering belt in the upstream of the seepage direction of the underground water is arranged; step 4, an area located at the downstream of the newly arranged dewatering belt in the seepage direction of the underground water is excavated. According to the foundation pit excavation method, dewatering is only carried out in the foundation pit, and thereforelarge-area sedimentation outside a pit can be avoided.
本发明涉及一种基坑开挖方法，该基坑开挖方法，该方法包括以下步骤：步骤一、在待挖基坑区域设置降水带，降水带与待挖基坑区域内部的地下水渗流方向交叉；利用所述降水带抽吸降水带设置区域的地下水，以将地下水阻断到降水带之前；步骤二、开挖在地下水渗流方向上位于降水带下游的区域；步骤三、在降水带的位于地下水渗流方向上游的一侧设置降水带；步骤四、开挖在地下水渗流方向上位于新设置的降水带下游的区域。该基坑开挖方法仅在基坑内降水，避免坑外产生较大面积沉降。
