The alphabetical A of mark represent the insertion tube device in some views, and it comprises that a shell that forms the device person in charge itself 1, one extend and playpipe 2 and nozzle 3 eccentric with it in shell 1.Nozzle 3 is contained in the lower end of pipe 2, is connected in such a way with pipe 2.Promptly the injection direction by nozzle is by means of the profile of shell itself or the top view on the ground of the Warning Mark on shell.
Shell 1 comprises a series of suitably isometric pipeline section, connects by means of the diaphragm 9 between bonding part 8 that forms on the pipe section and the pipe section that is inserted in adjacency.Diaphragm 9 is suitable for the pipe of fixing the inside, will make an explanation in suitable part later on.In the embodiment that has explained, though pipe section is along the shape of the trapezoid cross section bar of the injection direction diameter reduction of nozzle 3, pipe section can also conversion and is the shape of flange pipe, and the flange of this pipe is equipped with Warning Mark.When using the dihedral pipe section, pipe section can be clamped by the front by anchor clamps, and can not slippage.Therefore pipe section is just enough resisted big twisting moment, and can make device obtain truly having the operation of benefiting.The anchor clamps that reference numbers 4 representatives link to each other with the supporting and the rotary device 5 of insertion tube device, anchor clamps 4 comprise that being located at periphery goes up adjustable locator 6a, 6b again, separate angulately each other with angular distance thus, the insertion tube device is placed in optional position.Rotate by device 5 as the insertion tube device.When the angle between locator 6a, the 6b was made as α, each anchor clamps 4 and insertion tube device A just correspondingly rotated by angle [alpha], and converter 7 is met locator 6a or 6b.The direction of rotation of driving element 10 of just reversing anchor clamps.Therefore insertion tube device A continues by one and the alternately rotation of another direction.The angular distance of passing by and determining by angle [alpha].Install above-mentioned converter 7.And protrude upward from driving element 10.During in removing locator 6a and 6b any, its direction of rotation of insertion tube device A reversing, 360 ° of the each rotations of this device.Reference numbers 11 representatives are with insertion tube device A immigration downwards with from the underground device that shifts out.Drill bit 12 is contained in front end or the lower end of insertion tube device A, and when insertion tube device A alternately rotated by one and another direction continuously, drill bit 12 was excavated hole, a place in ground.When dredge operation is advanced and when increasing cavity depth, insertion tube device A is just slow gradually fall enter underground.The fulcrum that nozzle is supported blend stop 13 is placed on 14 places, bottom, arrives the spray nozzle 3 above the drill bit 12 thus, so that supporting spray nozzle 3, and can slide up and down along insertion tube device A.When the bottom 14 of supporting blend stop 13 when insertion tube device A moves up, the front end of supporting blend stop 13 just flatly stretches out from pipe unit A, and from insertion tube device A nozzle 3 is extended laterally thus.When playpipe 2 and shell 1 irrespectively moved up and down, nozzle 3 just can support blend stop 13 with nozzle and irrespectively move up and down.In insertion tube device front end one side that nozzle 3 one side opposites are installed a ultrasonic sensor 15 has been installed, has been opened a suck-back pipe 16 and a curing materials playpipe 17 in pipe unit A one side that ultrasonic sensor 15 places are installed.The hollow inside of shell 1 has formed suck-back pipe 16 in the embodiment that has explained.Reference numbers 19 is represented a sensor rope.Suck-back pipe and injection of material pipe 16,17 can be replaced by single common tube parts according to the type of used curing materials.
Because the structure and the layout of the parts of the said equipment, when operation, insertion tube device A is continuously by one and the alternately rotation of another direction, and with drill bit 12 when underground G excavates the hole, just transfer to underground G and go.When insertion tube device A transfers to underground hole of digging out; vertical tube 20 around the insertion tube device A protects just that the cave wall is unlikely to collapse; and come pumping stabilizing solution by pipe 18 simultaneously; be connected to suitable stabilizing solution source of supply (not shown) place in the outer end through pipe 18, and communicate at inner and pipe 18 and the insertion tube device periphery pipe 20 that enters the hole.Stabilizing solution is by to there eddy flow transmission, and with from ground and by excavating filling hole, causing and form that the soil that is cut of soil layer gained has formed mud around the hole.The stabilizing solution of eddy flow upwards is drawn into ground above the hole with the soil that is cut and mud by suck-back pipe 16.The composition of removing therefrom on the ground then stays stabilizing solution.So it is recovered in the hole by pipe 18 and pipe 20.When insertion tube device A has reached underground desired depth or hole and excavated underground desired depth, just under high pressure spray the soil layer that excavated material comes dislocation to limit the hole and form a base tunnel by injection into orbit pipe 2 and nozzle 3.According to about the illustrated the same manner of jetting stability liquid, the soil that is cut upwards is drawn on the ground by suck-back pipe 16.Except the swabbing action that itself provides by suck-back pipe 16, when suck-back pipe 16 is also loaded onto an auxiliary air pipe 21, can provide airlift usefulness, so that increase suction effect by auxiliary air pipe 21.Because the position of injection nozzle 3 can change by the control of said nozzle supporting blend stop 13, so desirable Any shape can be excavated in the hole.Under the stuffing pressure of the stabilizing solution of eddy flow, the cave wall can be protected, unlikely collapsing, and also the volume in hole and shape then detect by ultrasonic sensor 15.Detected volume and shape are transferred on the monitor (not shown) on the ground by sensor rope 19.By from nozzle 3 injection along the base tunnel wall under constant speed and constant voltage, reach the concavo-convex external forms of determining excavation by sensor 15, can obtain the data of relevant underground character, the shape in hole can be determined according to perceived soil property.
After the hole forms reservation shape, by curing materials playpipe 17 curing materials is ejected into and comes filling hole in the hole.Do not spray excavated material by nozzle when spraying curing materials, at this moment nozzle 3 or suck-back pipe 16 can be used as the curing materials playpipe according to the type of curing materials.
Curing materials can be selected by the combination that comprises cement, silicate of soda, acrylic acid amides, pitch, urine gastral cavity resin and isocyanates according to the specific solidification structures that will form.By repeating above program, just formed continuous solidification structures, perhaps in the specific region that this process can also be applied to reinforce.
Because the above-mentioned structure and the layout of device of the present invention just can obtain following effect.
Because the insertion tube device is continuously by one and the alternately rotation of another direction, rather than only rotation continuously in one direction, so just realized a kind of fabulous arrangement of mechanism, therefore monitor on the ground, underground sensor device, the mechanism of insertion tube device front end, on the ground apparatus for work and material feeding mechanism can be connected with each other satisfactorily by fairly simple device, when the insertion tube device rotates, unlikelyly be subjected to interrupted interference, as what in prior art, experienced.
And then because the anglec of rotation of insertion tube device, by crew-served converter 7 and adjustable locator 6a, 6b, can select arbitrarily to be provided with, this just can form a fan-shaped solidification structures in predetermined angular range, and solidification structures can be concentrated formation in the zone of accurately stipulating.
In addition, form solidification structures, thereby can replace by means of habitual piling operation and obtain high-intensity solidification structures owing to replacing the soil that is cut fully with packing material by means of rotary fluid.
Nozzle can limit solidification structures becomes a kind of optional or desirable shape.
The present invention has only at length represented with an embodiment and when illustrating, certain above-mentioned situation is the purpose in order to explain just, rather than regards limitation of the invention as.
