Equipment for combined work of piles shaped like Greek letter 'pi' and rectangular piles

The invention provides equipment for combined work of piles shaped like a Greek letter 'pi' and rectangular piles. The combined work process of a forming machine for the piles shaped like the Greek letter 'pi' and a forming machine for the rectangular piles includes the following steps that firstly, at the initial position of the axis needing pile forming, the forming machine for the piles shaped like the Greek letter 'pi' is used for manufacturing a cement soil inserting pile shaped like the Greek letter 'pi' in the working mode of the forming machine for the piles shaped like the Greek letter 'pi', a second cement soil inserting pile shaped like the Greek letter 'pi' is manufactured at the right side of the cement soil inserting pile shaped like the Greek letter 'pi' at the interval of one rectangular inserting pile, and in this way, multiple cement soil inserting piles shaped like the Greek letter 'pi' at the interval of one rectangular inserting pile are formed; a rectangular hole is formed in the interval between every two inserting piles shaped like the Greek letter 'pi' through the forming machine for the rectangular piles in the working mode of the forming machine for the rectangular piles, concrete is poured into the rectangular holes, one rectangular concrete inserting pile between every two inserting piles shaped like the Greek letter 'pi' is formed, and therefore a pile wall formed by wedge-shaped inserting of the cement soil inserting piles shaped like the Greek letter 'pi' and the rectangular concrete inserting pile between every two cement soil inserting piles shaped like the Greek letter 'pi' and used for soil retaining and leakage defending for a building foundation.
