Embodiment Construction
[0035] The present invention will be described in detail below with reference to the drawings and embodiments.
[0036] A manual digging pile system, such as figure 1 with figure 2 As shown, it includes a hollow pile hole 1 and a concrete casing 2 arranged on the wall of the hollow pile hole 1, and multiple concrete casings 2 are poured in sections from top to bottom. Two air exchange pipes 3 are pre-embedded vertically and oppositely in the concrete casing 2, and the air exchange pipes 3 in the upper and lower concrete casings 2 are connected by an adapter. By embedding two opposite air exchange pipes 3 vertically in the concrete casing 2, it is convenient to transport fresh air from outside to the hollow pile hole 1 through one of the air exchange pipes 3, and through the other air exchange pipe 3 The toxic gases and nitrogen-rich and oxygen-deficient gases in the hollow pile hole 1 are discharged, and the air exchange pipe 3 can also be used as a drain pipe, so as to facilita...
