NEBUTA NO IE – WA RASSE 090514 site visit
The site after the heavy rains of today. Because of these circumstances only 1 pile was installed. The next one was planned for friday the 15th of May. Eventually, because of trouble with the equipment, the second pile was installed on Monday 18th of May.
The construction of this years Nebutas has started. Through the entrance of one of the tents specially erected for the construction I could get a glimps of the wire and stick sub-structure being erected.
Today I attended the test piling session. First the dimensions of both piles were checked followed by the an inspection of the boring head (two diameters are used 750 for the shaft and for the last bit a widening to a 1100 diameter), calibration of the pile driver, the positioning of the pile hole, followed by the test boring and the inspection of the cement milk mix. First the two holes are drilled after which the piles are installed.
The inspection is not only meant to verify that the material is as specified but also to see the work flow. Each team has a different way of working and it needs to be ascertained that each step proceeds without problems. Today it was planned to install two piles but because of the weather conditions only one could be completed. On a day with good weather 4 piles are planned to be installed.
Also today the first audit was successfully completed.
After the drilling of the hole up to 27m the first part of the pile is inserted. The second part of the pile is welded on site to the first part to create a pile of the required 29m length. this image shows the welding of the two parts together.
