Shanghai Jintai SZ80-35 all casing drilling rig in Qingtian test pile excellent performance
The day before, a "pile open up a fresh outlook competition" in Zhejiang Wenzhou "Qingtian overseas Chinese economic headquarters building pile construction site. In pile test equipment are domestic famous brands of rotary drilling rig, the mud wall hole of the drilling machine, and in the mountains of southern Zhejiang widely used "Wu Kasi impact drill, and" Shanghai Jintai SZ80-35 all casing drill.
A seemingly ordinary pile foundation engineering, construction side is so, while the introduction of a variety of different scaled method in pile testing equipment, mainly is the complexity of the geology based on characteristics.
SZ80-35 is a new type of multi function drilling machine developed and manufactured by Shanghai Jintai Construction Machinery Co., Ltd., which has the following characteristics:
1. the main use of electro-hydraulic walking pile frame, grounding ratio down, column three point support structure, to ensure that the whole machine is very strong stability;
2. double power head configuration, two power head are respectively driven casing drilling / pulling and drilling, casing drive head output torque of 600KN.m, power head drill rod driving torque is 360KN.m, powerful driving force and the casing process combination, can adapt to the sand layer and gravel layer, stratum, rock and other types of Karst complex geological conditions;
The 3. drill pipe adopts the whole section spiral drill pipe, and the drilling process is drilled in the end, which greatly saves the manpower and time cost caused by adding the drill pipe;
4. the equipment is equipped with hydraulic Kim self-made slag bucket, bottom slag without the aid of other machinery;
5.SZ80-35 has great development space in multi process application. Besides long spiral drilling, it also uses DTH hammer, hydraulic hammer, SMW drilling rig, SMC drilling rig, etc. to realize pile construction, such as cast-in-place pile, secant pile, mixing pile and CFG, CFA and so on;
6. the pore size of the equipment is hole, the hole wall is regular, the pile hole vertical precision is high, and the slurry wall protection is not needed in the construction process, so as to achieve no mud discharge.
