Described are improved devices and processes for manufacturing concrete articles, including concrete pipe. In one embodiment, the invention provides an apparatus that has a first platform that is located beneath the floor of a manufacturing facility. The first platform includes a top surface and is configured to move bi-directionally along an axis. Two form bases can reside on the top surface of the first platform, each form base further including a form core that extends vertically from the first platform through respective holes in a second platform that resides above the first platform at an elevation even with or just above the floor's surface. The second platform is configured to move bi-directionally with the first platform between one of two cranes disposed on either side of a concrete mixer. A form is placed over the first core, which is then positioned under the outlet of an auger that receives concrete from the mixer. After filling is complete, the first core is positioned under the first crane which provides ballast to compress the concrete, and the second core (with a form) is placed under the auger's outlet for filling. After compression of the first form complete, the form can be removed using an overhead crane, and the second core is relocated to the second crane for concrete compression.

The present invention relates to a method for producing a tower segment of a concrete tower of a wind energy installation, comprising the steps: providing a segment mold having at least one formwork for defining a mold of the tower segment that is to be produced and for filling with concrete; filling the segment mold with concrete in order to form the tower segment by the subsequent hardening of the concrete; measuring the tower segment thus hardened for creating a three-dimensional, virtual actual model of said tower segment; producing said three-dimensional actual model; comparing the three-dimensional actual model with a predefined mold, in particular a stored three-dimensional, virtual target model; and determining a deviation between both virtual models and changing the segment mold, in particular changing the at least one formwork when the deviation exceeds a first predefined threshold value.

A manufacturing method of a concrete pile is shown. The method includes the following, that is, pouring concrete in the pile molding space, reducing the pile molding space to compress and mold the concrete, draining water drained from the concrete by compression and molding outside of the formwork from the drainage hole, and holding the concrete a predetermined amount of time to harden the concrete. The formwork includes an outer formwork that molds an outer wall surface of the concrete pile, an inner formwork that molds an inner wall surface of a hollow space of the concrete pile, and a pair of end formwork that mold upper and lower end surfaces of the concrete pile. The drainage hole is a gap between adjacent components when the mold is tightened, and the gap is configured to be capable of being opened larger during cleaning than when the mold is tightened.
