Pipe Jacking Machine/MTBM
Jiangsu Jueyan Heavy Industry Technology Co., Ltd
Jiangsu Jueyan Heavy Industry Technology Co., Ltd.Is located in Changzhou, a well-known and economically developed city that is in the Yangtze River Delta with advanced economy and advanced technology.With strong technical force and advanced production technology, the company has a scientific research team with decades of experience in the non-excavation industry.The current product line has a series, multi-function and miniaturization.Decades of industry precipitation, hundreds of cases have accumulated, and the first composite pipe jacking machine developed in China.
Q:What is Compound Pipe Jacking Machine?
A:The design concept of the composite pipe jacking machine is:A soft soil machine that is commonly used in composite soft soil layers, and this machine can be remoulded to a hard rock machine that can be used for rock surface construction by changing the cutting cutter;Our newest machine has enough space for operators to change the cutting cutter during the tunneling process when the diameter of pipe jacking machine is bigger than 1500mm,also the earth pressure balanced pipe jacking can be completed by replacing the screw excavator.
Q:What is the performance of Compound Pipe Jacking machine ?
A:The whole machine is waterproof (Chinese patent number ZL201822154528.0).
Without changing the operator's operating habits, in the normal jacking, the pit laser transmitter is still used to monitor the head jacking latitude and longitude changes, and an intelligent sealed warehouse is added.In case of emergency or off duty, the "tail warehouse" "Door open" and "Tail warehouse door close" conversion buttons perform one-button opening and closing actions, which effectively improves the effective protection against water permeation that may occur at high water levels, severe weather, and operating errors, and the waterproof rating is IP67.
By removing the crushing wheel and the attachment of cutter head , this machine can be remoulded to the panel machine which is more efficient for silty clay layer construction and the machine can be remoulded in the construction site.(accessories included)
There is no need to return to the factory.By replacing the rock cutter head on the site and connecting the front monitor, the rock machine required for pure rock geology can be formed (sold separately).
According to many years of construction experience, we combined with actual working conditions.We developed electronic integrated control system independently, that can control the pump and valve group components integratedly during the entire construction process.Also, the whole process of construction can be convenient, simple, safe and reliable.
Geological conditions applicable to factory equipment (patent application number 20191078525.4)
A.It is suitable for pebble layer, sand pebble layer, soil pebble layer with particle size <= 30% of its own pipe diameter.
B.Miscellaneous filling layer (no steel bar, large amount of non-degradable soft domestic garbage), plain filling layer;
C.Suitable for all kinds of hard non-strongly cohesive soil layers with uniaxial compressive strength <= 10MPa;
D.Combined with soil improvement media to adapt to various sand layers;
Special Design
Power system of the equipment , correction system of the pumping station, bypass system, pressure monitoring system and control system can all be designed for intercommunication of adjacent pipe diameters.Example:Ø800 and Ø1000 can be shared;
