Actually fences and nets is something that is present here. But obviously they cannot cover the hole completely because how else they would then dig this soil out? What actually do you suggest for alternative, because I can't see any?

I just found this picture from 2009 at the East Pacific Centre construction site, they were doing something similar back then. I've never seen this at any other Chinese cities though, only Shenzhen.

Hi all.

Hi hmmwv.
Great find.
How close to this site is the East Pacific Center ?
Very interesting to see they do this technique regularly - even the small piles look to be done with the same method as here.

Hi Konta.
Good points.
Still seems rather primitive.
I will say, the pouring of concrete rings to prevent collapse allowing the top to remain open, is much better than the pressurized caisson method of a hundred years ago. That method was used on the Singer building (among
many others) in 1908 and was quite a feat of engineering at that time. They went down 90 feet.

Hi all.

Hi Killer.
Thanks. The 2 sites look to be ~ 3 km. apart.
Fairly close. I wonder if this method of digging piles by hand is a requirement or a choice ?
The red line on the map is the metro line ?
If so it runs close to the other site as well.

So, is this a required method only on sites above the line ?

Inquiring minds want to know.


Ray.

Found some introduction of this piling method:http://b.baidu.com/view/2466627.htm
It goes like this after I put it on translate.google.com(Well,it's that "Hand-dug piles" ):

Hand-dug piles, engineering terms, with human excavation, on-site pouring of concrete piles. Hand-dug piles thicker in diameter, the smallest are 800 mm or more, can carry less and pressure of the floor structure of the main current applications are more common. Set above the pile caps, pile cap beam and then Rachel, linked together, so that each pile evenly distributed force to support the entire building.

Hand-dug piles of construction convenient, fast, no large-scale machinery and equipment, dug pile than the wood piles, concrete piles into the strong earthquake, cost more than red cones punching, punching the impact of cone, impact drill punching, swing rig drilling caisson foundation savings. To the highway, civil construction has been widely used. But dug pile underground work conditions are poor, poor environment, labor-intensive, safety and quality is very important. The venue is strictly prohibited to play down deep pumping, when really need to take a small area due to pumping of construction, attention should be on the surrounding ground and buildings to observe the abnormal situation should be handled promptly notify the relevant units

Wall using c25 concrete piles, steel using r235; the first deepening of about one meter, pouring concrete casing, down to every section of the construction as a construction cycle (ie, pouring concrete, dug every Wall Festival); In order to facilitate the well organized drainage, permeable layer in the reserved section of the Wall scuppers (aperture in the same pipe diameter), taken over in order to facilitate drainage and prior to the pouring of concrete to plug in order to ensure the verticality of the pile, which require each casting finished three Wall to be checked and the center of the pile verticality time; in addition to the piers in the ground outside the position of four weeks to dig ditches and holes should be properly discharge the water outside the drainage holes away from the pile hole. Concrete in the pile foundation, pile holes are shown with only a small amount of seepage should be taken while pouring to avoid a hole concentration of the water more difficult. Such as the porous volume, affect the quality of perfusion, pumping should be concentrated in the hole, reducing the water level in the other hole, this hole final pouring of concrete under water construction; digging holes, if you encounter a large water inflow layers of pressurized water diving , can be cement mortar grouting pebble ring will be closed diving layer processing; dig holes to reach the design elevation, the bottom of the hole should be handled, must be smooth, no loose slag, sludge and other soft sediment layer; not entirely place in strict accordance with current national standard construction procedures.
