With the 6th stage for installing steel supporting material (50).As shown in Figure 2 a, the first stage of interception portal (10), is tunnel to be built
The stage that portal (10) is intercepted in a vertical direction.As shown in Figure 2 b, the second stage of nose girder (20) is installed, is intercepted above-mentioned
Portal (10) position is installed by the stage of tunnel-shaped nose girder (20).Above-mentioned tunnel-shaped nose girder (20) is main to install leading for arch
Beam (20) (reference picture 3 and Fig. 4), is drilled patchhole (30) with them as supporting member, thus improves patchhole (30) precision.Edge
Nose girder (20) center line and form through hole (21), with this through hole (21) for supporting member is drilled patchhole (30), or with nose girder
(20) outside is supporting member, patchhole (30) of being drilled on the outside of it, therefore borehole accuracy is higher than conventional art, it is also possible to long
Distance drilling, with sufficiently long steel pipe (40) supporting tunnel, increases tunnel support effect.As shown in Figure 2 c, drill patchhole
(30) phase III, be along nose girder (20) axially, the stage of (30) of being punched side by side by appropriate intervals and tunnel travel direction.
As it was previously stated, consistent on the through hole (21) that can be centrally formed in nose girder (20) of above-mentioned patchhole (30), or by appropriate intervals along
Nose girder (20) outside is formed.As shown in Figure 2 c, the fourth stage of steel pipe (40) is installed in insertion, is the steel formation grout hole (41)
Stage of the pipe (40) installed in patchhole (30).Drilled patchhole (30) shape according to aforementioned stages, steel pipe is mounted with arch
(40).Above-mentioned steel pipe (40) be inserted into patchhole (30) it is inner after, be welded and fixed end and the nose girder (20) of steel pipe (40), or
Steel pipe (40) upper locking nut that end forms screw (43) fixes nose girder (20) and steel pipe (40), thus integration steel pipe
(40) strong construction of tunnel portal (10) and nose girder (20), is built.
In addition, on steel pipe (40) formed above-mentioned grout hole (41), according to foundation situation etc. regulation formed its diameter and
Interval, by above-mentioned grout hole (41), can jet grouting material in the aftermentioned stage.Above-mentioned grout hole (41) both may be formed at whole steel
Pipe (40) periphery, can also be only formed in steel pipe (40) outside half position (reference picture 7a).Here outside half position meaning
Positioned at the semi-circular portions of tunnel lateral direction when installation steel pipe (40).Therefore, in following stages, bootable grouting mainly exists
Implement at steel pipe (40) outside half position.The grout hole (41) formed on above-mentioned steel pipe (40), can be by its outside and inner side
Diameter is mutually perpendicular to, but grout hole can also be inclined, or grout hole outside is different with inside diameter.For example, can be grouting
Hole (41) to steel pipe (40) behind, i.e., tunnel portal (10) direction is formed slopely (reference picture 7b), in such case, steel pipe (40)
When being inserted into patchhole (30), the grout hole clogging for staying in the inner small stone of patchhole (30), soil causes can be prevented.And
And, the grout hole (41) (reference picture 7c) of inner wide and outer narrow can be formed.Now, big grain sand or stone etc. are prevented to grout hole (41)
The inflow of inner side.Even flowing into granule sand or stone, also the narrow apertura lateralis granule than inner wide and outer narrow is flowed into, grout hole (41)
Will not block, and sand, stone for flowing into etc., jet grouting material can be followed to extrude.I.e. certain diameter when, can occur in the middle of hole
The phenomenon of the stone of irregular shape is blocked, but during inner wide and outer narrow, it is difficult to there is this phenomenon.And grout hole (41), outside it
Side can form multiple otch (411) (reference picture 7d and Fig. 7 e).Now, even if getting into big sand, gravelstone grout hole (41) is inner
Head, also can spray husky or stone by the injection material pressure of otch (411), prevent the blocking of grout hole (41).Above-mentioned otch
(411), on the grout hole (41) of certain diameter, or on the grout hole (41) of inner wide and outer narrow diameter, be able to can be formed.Grouting
5th stage be steel pipe (40) it is inner injection injection material come grouting steel pipe (40) and its around stage.Therefore injection material is penetrated into
Around steel pipe (40), steel pipe (40) can be made to be integrally formed with the ground around steel pipe (40), even if being dug by following stages
Pick, it is also possible to prevent caving in for ground etc. (reference picture 3 and Fig. 4).It is now real between patchhole (30) entrance and steel pipe (40)
Ca(u)lk is applied to prevent from injecting the leakage of injection material.As shown in Figure 2 d, the 6th stage of steel supporting material (50) is installed, is while excavating
While installing steel supporting material (50) comes supporting steel pipe (40) and tunneling stage while tunnel internal.Above-mentioned steel supporting material
(50) outside, is isolated to form projection (51) (reference picture 3 and Fig. 5) by appropriate intervals, makes steel pipe (40) positioned at each projection
(51) between.Above-mentioned projection (51) steel supporting material (50) is formed, steel pipe (40) is supported inside and outside, greatly enhances the branch in tunnel
Shield effect.
Conventional art situation, is present because the poor direction of steel pipe (40) is true, and steel pipe (40) and steel supporting material (50) are mutually
Isolation, steel supporting material (50) cannot correct supporting steel pipe (40), and steel pipe (40) is not by its both sides direction, i.e. tunnel circumference side
To support, it may occur that lateral flow, so that situations such as tunnel internal ground occurs caving in, steel pipe (40) can also be inclined simultaneously
Or flow, therefore steel pipe (40) can not normally be supported and be mined tunnel internal.But in the present case, with steel pipe
(40) installation direction is correct, and steel pipe (40) is radially supported securely by steel supporting material (50), and by projection (51), steel pipe
(40) laterally, i.e., the support on steel supporting material (50) axial direction is also firm, therefore stabilization is by support tunneling.For projection
(51), can be formed on all steel supporting materials (50) of tunnel internal.But also only formed in part steel supporting material (50) on demand.
And projection (51) is not limited to shape shown in drawing, as long as even energy lateral stability supporting steel pipe (40), any shape.Separately
Outward, above-mentioned 6th stage may include the process of steel supporting material (50) axial pressure.Spiral thousand is installed i.e. in steel supporting material (50)
Jin top (60) (reference picture 3 and Fig. 5) simultaneously starts it, can be by steel supporting material (50) axial direction, i.e. steel supporting material (50) length direction

Mounted in this burble point, can also be arranged on all points for steel supporting material (50) end separate.Moreover it is possible to be installed in all
Steel supporting material (50) of tunnel internal separates several, it is also possible to separate a part therein, screw jack is installed afterwards
(60).It is no to add because steel supporting material (50) is simple supporting steel pipe (40) and is mined tunnel foundation on conventional art
Laminated structure, it is impossible to the normal cracking for suppressing tunnelling face, the phenomenon such as relax, cave in, caving in of ground.Conversely, it is of the present invention because
By screw jack (60), steel supporting material (50) is compressed by axial direction (length direction), steel pipe (40) is radially distensible, thus presses
Contracting supporting steel pipe (40) and tunnel foundation is mined laterally, so the present invention is prevented or suppressed, and tunnel is cracked, ground relaxes, collapses
The phenomenon, the technology with effect well such as collapse, cave in.
The present invention, can be regardless of the first half in tunnel and latter half of, and whole tunnel is disposably built by the above-mentioned stage,
Tunnel can also be divided into first half and lower half, the first half is only built by the above-mentioned stage, then supplement builds the lower half in tunnel
Portion, whole tunnel is completed with this.
