Description
The present invention is the shield tunnel excavator that adopts shielding cylinder.Specifically, in the earth chamber that shielding cylinder is spaced previously, the viscosity of excavating the native sand that comes out is improved, then, be not intactly will appear to have those earth that to discharge from the earth chamber to discharge immediately, but,, particularly can will make the mud effect and further improve in that system mud is indoor in the digging field (in that structure that the tunnelling face that promptly prevents crumbles) according to the pressure size of earth.Technical scope of the present invention is exactly relevant with such shield tunnel excavator.
Generally, the shielding mining method is so that an example of tunnelling method that soft region was carried out is celebrated.So-called shielding mining method, in fact be exactly with shielding cylinder, be about to guarantee when this can make excavator operate that the device cylindrical shell of the steel that it has certain operating space constantly pushes ahead under surface layer, on one side ground is inserted in the front portion of the shielding cylinder of this steel, the tunnel excavated on one side.Meanwhile, above-mentioned shielding cylinder is pushed ahead, the ground surface around the tunnel, cylindrical shell top of Xing Chenging is guaranteed and unlikely subsiding therefrom.This is because in advance the arcuation body result that combine of the rearward end of shielding cylinder with the former arrangement in the form of a ring that is connected, because the propelling of above-mentioned shielding cylinder and guaranteeing and can carrying out continuously of the face of land, tunnel are so also can build the tunnel at broken ground.
For the ease of understanding, the spy will describe it in detail according to the 1st figure and the 2nd figure as the technical design thought in the past on basis of the present invention.In the tunnel excavator as shown in the drawing, after the diesel engine b startup of the shielding cylinder a that is suitable for the mountain region is advanced, rotating sharpener c has just rotated, and in rotary cutting tool bit d place of arrival, digging field, sand has been excavated immediately.In diesel engine b running, when the system mud material when ascending pipe e delivers to earth chamber f, rotary cutting tool bit d excavates, agitator g will import the native sand of earth chamber f and make mud material and mix, stir.At this moment, in the f of earth chamber, obtain well-beaten native sand and the system mud material has become earth with moderate plastic fluidity and impermeability.And, in case be full of earth among the automatic transmission machine barrel machine h that the earth in the f of earth chamber can be sent, can keep soil pressure with the spiral transmitter i in the automatic conveyer cylindrical shell h and crumble and groundwater pressure to resist the digging field.It is to be monitored by the soil pressure meter k that is arranged on dividing plate j place that earth in the f of earth chamber is pressed.Crumble and ground water pressure for resisting the digging field, when insufficient pressure, can make the revolution of the spiral transmitter i in the automatic conveyer cylindrical shell h reduce withstand voltage to increase, perhaps, can also detect the fltting speed that whether is necessary driving the shielding cylinder l of shielding cylinder a improves withstand voltage to increase.
And spiral transmission i rotates continuously, and the suitable earth of viscosity that obtains in the earth chamber is little by little moved on in the automatic conveyer cylindrical shell h.The earth that moves on in the automatic conveyer cylindrical shell h is sent from spiral transmitter i rear portion outlet opening m, again from outlet opening m falls hopper o on the belt conveyor n.The water content of the earth of being sent by belt conveyor n and the water content in natural mountain region are practically identical, can carry out processed and carry out by original state.In addition, f front, whole earth chamber is actually that we opens, and the earth pressure in the f of earth chamber is added to the digging field, can also resist ground water pressure when preventing to crumble.And, because earth chamber f and automatic transmission machine barrel a(should be " shielding cylinder a "-translator) interior no gap, be full of earth with impermeability, in fact just can stop underground water to flow in the shielding cylinder a.Shielding cylinder l orders about shielding cylinder a to be continued to move forward, and uses the tunnel surface of the part p guard shield cylindrical shell a back of shielding cylinder back and its overlap joint on the one hand, and the tunnel is extended forward gradually.
, in the structure shown in the 1st figure and the 2nd figure, when the diameter in the tunnel of required excavation, build relatively hour can obtain satisfied result; Yet, satisfying the increase of tunnel diameter and when shielding cylinder a diameter is increased, the radial direction of rotating sharpener C is away from axle center one side (following all title " outer ring "-translators) and variant near the linear velocity of axle center one side (following all title " inner ring "-translators), thereby the mixing power of the agitator g of earth chamber f Internal and external cycle and inner ring has produced the ripple reputation, just can not form the earth of homogeneous quality in the f of earth chamber, particularly the soil pressure in whole earth chamber f is inhomogeneous, so can not keep evenly the soil pressure of whole digging field, this just might be owing to the digging field safety that makes the operator that crumbles can not get assurance.
As mentioned above, the present invention aims to provide a shield tunnel excavator that can be achieved as follows: the fluctuation of the mixing power in the earth chamber reduces significantly; Owing in whole earth chamber, can obtain uniform mixing power, so can form the earth of homogeneous quality; Owing to prevent that the digging field from crumbling effectively, so that operator's safety guaranteed fully.
