Deep foundation pit rapid unearthing construction method by combining trestle with in-pit road
The invention relates to a deep foundation pit rapid unearthing construction method by combining a trestle with an in-pit road. The construction method comprises the following steps that excavating is performed at a set position to form a first support foundation trench, and a first support beam is constructed in the first support foundation trench; the first-layer earthwork of the foundation pit is excavated, a transportation trestle is constructed on one side, and the transportation trestle formed through construction is located at the top of the foundation pit and connected with the two opposite sides of the foundation pit in a jacking and supporting mode; and a transportation ramp connected with the transportation trestle is laid in the foundation pit, the next layer of earthwork of the foundation pit is excavated, the next supporting beam is constructed, in the earthwork excavation process, the earthwork is transported out of the foundation pit through the transportation ramp and the transportation trestle, and the step is repeated till the earthwork in the foundation pit is excavated. The transportation trestle and the transportation ramp are arranged to connect the bottom of the foundation pit with the top of the foundation pit, so that an earthwork vehicle can directly convey earthwork out, and the excavation efficiency is improved; and in the excavation process of each layer of earth, the corresponding supporting beams are constructed firstly, the foundation pit is supported through the supporting beams, and stability and safety of the foundation pit are guaranteed.
本发明涉及一种深基坑利用栈桥结合坑内道路快速出土施工方法，包括如下步骤：于设定位置挖掘形成首道支撑基槽，并于首道支撑基槽内施工首道支撑梁；挖掘基坑的首层土方，并于一侧施工运输栈桥，施工形成的运输栈桥位于基坑的顶部并顶撑连接基坑的相对两侧；于基坑内铺设连接运输栈桥的运输坡道，挖掘基坑的下一层土方并施工下一道支撑梁，在挖掘土方的过程中，利用运输坡道和运输栈桥向基坑外运送土方，重复该步骤直至基坑内的土方挖掘完成。本发明设置运输栈桥和运输坡道连接基坑底部与基坑顶部，使得土方车能够直接将土方输送出去，提高了出土效率。每层土方开挖的过程中，均先施工对应的支撑梁，利用支撑梁支护基坑，确保基坑稳定和安全。
