Abstract
A pipe pile-jet grouting pile united supporting underground wall structure comprises prestressed pipe piles pressed into earth at intervals. The prestressed pipe piles surround the periphery of a basement to be constructed for a circle. High-pressure jet grouting soil-cement piles are tightly arranged between every two adjacent prestressed pipe piles side by side so that united piles can be formed. The earth is dug from top to bottom in sections. Reinforced concrete basement annular wall bodies are poured from top to bottom in sections at the inner sides of the united piles. The annular wall body at the upper layer and the annular wall body at the lower layer are connected through the instant grouting method, so that a basement continuous wall is formed by the annular wall bodies at the layers. Wall attached columns can be arranged in each annular wall body. Anchoring pulling ribs or pile hoops are arranged on each prestressed pipe pile at intervals in the length direction and connected with pulling connection pieces of the basement continuous wall, so that a whole waterproof body is formed by the basement continuous wall and the prestressed pipe piles. The pipe pile-jet grouting pile united supporting underground wall structure is convenient to construct, reliable in construction, capable of omitting temporary supporting cost, free of bad influence on the environment, free of the requirement for earthwork backfilling and short in work period.
