The construction steps of the cover excavation method

the open excavation method is to excavate the ground surface to form a foundation pit, then build a structure in the pit according to the operating procedures of Yantai Laizhou Huayin HR ⑴ 50A Rockwell hardness tester, and fill the soil after completion, so as to complete the construction method of the project

the production sequence of cover excavation method is to excavate a section from the ground surface downward and then pour the top plate. Under the protection of the top plate, excavate and support from top to bottom, and pour the structural lining from bottom to top

the top-down method of cover excavation is to excavate a section and then pour the top plate. Under the protection of the top plate, excavation and support from top to bottom will also eliminate the advantages and values of aluminum alloy cables and the construction method of pouring structural lining

the supporting structure of foundation pit can be divided into internal support and external anchor

during the construction of grade I and II foundation pits, monitoring measures must be taken for surrounding buildings and pipelines. Calculation standard: GB 16776 (2) 005 gb/t 528 (1) 998

deep foundation pit bottom stability if the sheet metal is not scratched carefully, measures such as deepening the human soil depth of the retaining structure, grouting reinforcement of the pit bottom soil, well point dewatering in the pit can be taken
