Earth cutting method for soil discharge slope of deep foundation pit
An earth cutting method for an earth discharge slope of a deep foundation pit comprises the following construction procedures that firstly, preparation work before construction is conducted; secondly, a base is excavated, wherein excavation of a soil discharging slope is conducted after other parts of the foundation pit are constructed to the base; step 3, detecting the excavated ramp; step 4, excavating in layers and stages, and excavating earthwork 5m below the earth surface of the soil discharge ramp by adopting a common excavator; fifthly, concrete is sprayed between anchor rod waist beam piles for construction and maintenance, meanwhile, earthwork is transferred to the soil discharging slope, and sixthly, a long-arm hook machine is used for excavation 5-12 m below the earth surface; and step 7, same as the step 5 in working procedure, concrete is sprayed between anchor rod waist beam piles for construction and maintenance, meanwhile, earthwork is transferred to the soil discharging slope, a common excavator, a long-arm excavator and a small excavator are adopted to be matched with a foundation pit supporting structure for construction, simultaneous excavation is conducted according to the slopes with different depths, the engineering construction progress can be accelerated, and the construction efficiency is improved. And idling of mechanical equipment is reduced.
一种深基坑排土坡道挖土方法，包括以下施工工序，步骤一：进行施工前的准备工作；步骤二：基底开挖，排土坡道的开挖在基坑其他部位施工至基底后进行；步骤三：对开挖后的坡道进行检测，步骤四：分层、分阶段开挖，排土坡道地表下5m土方采用普通挖掘机进行开挖；步骤五：对锚杆腰梁桩间喷射混凝土施工并进行养护，同时排土坡道进行倒运土方，步骤六：使用长臂钩机对地表下5‑12m进行开挖；步骤七：和步骤五工序相同，对锚杆腰梁桩间喷射混凝土施工并进行养护，同时排土坡道进行倒运土方，采用普通挖掘机、长臂挖掘机、小型挖掘机配合基坑支护结构施工，并根据不同深度的坡道进行同时开挖，能够加快工程施工进度，减少机械设备窝工。
