Each 3 meters of left and right, intensity index are not less than 0.8Mpa for 28d.Cement system, which reinforces, can facilitate grouting at the tail of the shield machine to form hoop, close shield
Structure rear water.
Step 2：Further reinforced into hole portal using Horizontal Freezing method, it is specific as follows：
As Figure 2-3, the Horizontal Freezing method is used in the method into setting freezing hole 41 on the portal of hole, shape
Into reinforcing area 6 is freezed, specifically, freezing hole 41 is divided into 3 circles and is arranged, and freezing pipe 61 is set in freezing hole 41.It is preferred that
Ground, sets 34 freezing holes 41, it is 3.5m effectively to freeze length in portal outer ring 4；Set altogether in portal centre circle 3 and portal inner ring 5
25 freezing holes 41 are put, effectively freeze length 2.4m, wherein portal outer ring 4 is located at outside portal, and portal inner ring 5 is located in portal
Portion.The mean temperature of frost wall reaches -10 DEG C at into hole hole, and by consolidation by freezing, the soil body can be prevented when portal is cut
Cave in and percolating water.
Further, as shown in figs. 4 and 6, a coil spring steel plate 12, the spring steel are welded in the steel ring into hole portal
Plate 12 is tiltedly located on susceptor plate 123 by two blocks of steel plates 122 are parallel, and between two blocks of steel plates 122 filling sponge 121, it is necessary to
It is noted that the position that steel spring plate 12 is set cannot shelter from the envelope curved plate at hole, this setup can either have
Anti- leak-stopping mud sand leakage is imitated, and can guarantee that sealing grouting quality.
Step 3：Described into assembled steel jacket box 8 in the portal of hole, as shown in figure 4, specific as follows：
1) it is first that adjustment ring 81, standard ring 82 is cyclic in installation on ground, adjustment ring 81 and standard ring 82 are connected with；
2) adjustment ring 81 and the steel ring into hole portal are welded together, specifically, by adjustment ring 81 and standard ring
82 priorities are hung in into being installed in the hole of hole, and adjustment ring 81 and standard ring 82 are connected with, while adjustment ring 81 and portal
Steel ring is welded to connect, and ensures to weld seamless.It should be noted that due to having been subjected to consolidation by freezing into hole hole,
First the freezing pipe 61 of portal inner ring 5 is disconnected temporarily when steel jacket box 8 are installed, after steel jacket box 8 installs, then by the jelly
Knot pipe 61 passes through steel jacket box 8, and recovers connection again；
3) finally rear end cap 83 and the standard ring 52 are connected with, form counter force system, it is preferable that can bear

4) concrete is laid with 8 bottom of cylinder sleeve case, specifically, as shown in figure 5, in 60 ° of 8 bottom of steel jacket box model
Interior laying concrete layer 84 is enclosed, the preferred low grade C20 plain concretes of the present embodiment, thickness 12cm, both can guarantee that carrying shield
The ability of machine, and can guarantee that and do not damage cutter head of shield machine, after the completion of laying, 83 wicket of sealed rear end cover.
Step 4：Shield machine is received using the steel jacket box 8, as shown in fig. 7, specific as follows：
1) shield machine is in place, and specifically, shield machine is advanced into cutterhead apart from 2 meters or so positions of Horizontal Freezing body frost wall
Shutdown is put, makes cutterhead avoid cutterhead from being frozen in outside freezing influence area；
2) chisel into hole portal, specifically, into lateral aperture is set in the range of the portal of hole, the present embodiment is preferably in " rice " word
Shape sets lateral aperture, it is preferable that and lateral aperture sets 9, aperture 8cm, and brill depth is 2~3m, while observes portal water leakage situation,
If normal, start the door that holes, it is preferable that portal is cut from top to bottom, partly wall 11 is first cut, pulls out in the range of portal
Freezing pipe 61, and freezing hole 41 is blocked in first time, the present embodiment is preferably using cement mortar closure freezing hole 41.Need to note
Meaning, pays special attention to protect freezing pipe 61 during cutting.Then with cutting remainder wall 11, and dial except ground 11 outermost of wall
The reinforcing bar of row, is chiseled into hole portal；
3) shield machine is pushed into the steel jacket box 8, and the steel jacket box 8 is filled with filler, specifically, due in shield
When structure machine is pushed into steel jacket box 8 so that pressure constantly raises in steel jacket box 8, in order to allow 8 timely release of steel jacket box, is filled out with filler
Steel jacket box 8 is filled, it is filler that the present embodiment, which preferably flows shape soil, stream shape soil is full of steel jacket box 8, it is ensured that steel jacket box 8, which seals, not to be leaked.
Step 5：Shield machine is constructed described in entering into hole portal, specific as follows with continued reference to Fig. 4 and 7：
1) shield cutter system is unlocked, specifically, shield cutter system is unlocked, remains that cutterhead rotates, it is so anti-
Only cutterhead is frozen；
2) shield machine is promoted, forms tunnel, specifically, shield machine is slowly advanced, and knife cutting Frozen Soil 13, makes Frozen Soil
13 fully cuttings, the Frozen Soil 13 are integrally pushed into the native storehouse of steel jacket box 8.It should be noted that cutterhead meeting before upper access bridge
Stop operating, at this time enter empty push-model, pressure in steel jacket box 8, before cutterhead stops operating, tries one's best out when being pushed away for mitigation sky
Soil in empty soil storehouse, can when sky pushes away using belt conveyor of shield machine by 13 dispatch of Frozen Soil in native storehouse to outside
Using Tu Cang pressure in steel jacket box 8 is reduced into soil.Preferably, when shield machine thrust and excessive soil pressure, open steel jacket box 8 and let out
Pressure valve carries out release；Using assembling machine manipulator's assembly tunnel duct piece 14 in shield machine, tunnel is formed, it is preferable that in cutterhead
Before completely by Frozen Soil 13, tensed using drawknot device into hole section tunnel duct piece 14, prevent tunnel duct piece 14 from loosening displacement.
3) shield machine is shut down after being advanced designated position, specifically, when shield drive end unit leaves about 1 meter of liner 10,
Meet that shield machine is shut down into during the envelope steel plate requirement of hole portal.
Step 6：After the completion of the shield machine construction, to carrying out slip casting into hole hole, hole hole is sealed into, it is specific as follows：
1) to carrying out secondary grouting into the last 10 ring tunnel duct piece 14 of hole portal, specifically, in tunnel duct piece 14 into
Hole endless tube piece 141 uses dual slurry slip casting, and single slurry slip casting is used to remaining tunnel duct piece 14.Carried out into hole endless tube piece 141 double
Fully to be tamped into hole endless tube piece 141 and portal steel ring gap during slurry slip casting, be conducive to block leakage passage；
2) after slip casting solidification, if 14 injected hole of tunnel duct piece cuts off the adjustment ring 81 in steel jacket box 8 without leak；
3), specifically, will by the steel ring steel plate welded seal into hole endless tube piece 141 and into hole portal in tunnel duct piece
What is exposed uses steel plate welded seal into hole endless tube piece 141 and portal steel ring.The present embodiment is preferably used into hole endless tube piece 141
Steel plate section of jurisdiction is born, can ensure to protrude liner 10 into hole endless tube piece 141, be conducive to thoroughly separate leakage passage.
Obviously, those skilled in the art can carry out invention spirit of the various modification and variations without departing from the present invention
And scope.If in this way, these modifications and changes of the present invention belong to the claims in the present invention and its equivalent technologies scope it
Interior, then the present invention is also intended to including these modification and variations.
