Construction method of traffic trunk road basement channel
The invention relates to the technical field of earthwork construction, in particular to a traffic trunk road basement channel building method. The method comprises the following steps: manually dividing a ground construction area into a plurality of single vertical shaft pre-digging areas; the pre-excavation areas of the two head single vertical shafts are excavated in sequence to form independent single vertical shafts; the two head single shafts penetrate through; performing backfilling and soil covering on the two head single vertical shafts to recover traffic; the next single vertical shaft pre-excavation area continues to be excavated to form a single vertical shaft again, and penetrating is conducted in time; backfilling and soil covering are carried out again; and according to the method, earthwork operation of the remaining single vertical shaft pre-excavation areas is completed in sequence. Therefore, on one hand, the construction length of each single vertical shaft is relatively limited, and side wall reinforcement, soil retaining and underground water leakage prevention treatment can be conveniently executed with low cost and low construction difficulty; on the other hand, after the single vertical shafts are excavated, the single vertical shafts can be backfilled and covered with soil in time, the influence on the surrounding environment is reduced, and the traffic capacity of part of lanes is kept all the time.
本发明涉及土方施工技术领域，尤其是一种交通干道地下室通道建造方法。对地面施工区域进行人为划分，以分隔为多个单体竖井预挖区域；依次开挖两头部单体竖井预挖区域，以成形独立的单体竖井；贯通两头部单体竖井；对两头部单体竖井进行回填、覆土，以恢复交通；继续开挖下一单体竖井预挖区域以再次形成单体竖井，并及时进行贯通；再次实施回填、覆土作业；参照上述方法，依序完成剩余单体竖井预挖区域的土方作业。如此，一方面，各单体竖井的施工长度相对有限，便于低成本、低施工难度执行侧壁加固、挡土及防地下水渗漏处理；另一方面，单体竖井被开挖后，均可得到及时地回填、覆土，利于降低对周边环境的影响，且始终保留部分车道的通行能力。
