Description
Technical field
The present invention relates to bind section of jurisdiction and the column of a kind of assembly of shield duct piece, more particularly to a kind of fissure of displacement rectangular shield
The splicing structure and method of section of jurisdiction.
Background technology
Pipe sheet assembling is an important subdivisional work in shield method tunnel construction, is occupied very in Analysis on Shield Tunnel Driven Process
Special position, vital effect is played to whole engineering.Pipe sheet assembling quality directly affects the stress shape of shield tunnel
Condition, influences the quality of whole engineering.Pipe sheet assembling is improper easily to there is faulting of slab ends, subtended angle, anchor ring injustice, produces local stress collection
In, and then section of jurisdiction fragmentation, seepage may be caused, or even there is the consequence that lower endless tube piece can not be assembled.
In rectangular shield method constructing tunnel, Rectangular Tunnel section of jurisdiction (setting up post in centre) is spelled using staggered joint erection mode
Dress construction, tunnel segment structure form is increasingly complex, and no similar engineering is referred to, and assembled process is more difficult to control, be mainly shown as with
Under several aspects：
1) assembled theory difference is big
Based on the functional characteristic of the special assembling machine of rectangular shield, rectangle pipe sheet assembling sequential selection, movement, positioning etc. are relatively round
Shape tunnel is different.The cyclization of circular tunnel section of jurisdiction normally only controls the insertion of " crucial block ", but Rectangular Tunnel tunnel segment structure
It is special, when controlling " crucial block " insertion, it is necessary to while ensureing the headroom size in direction anyhow.
2) ring highness change difficulty is big
The connected mode of oblique bolt is used between rectangular tube loop and ring, adjustable clearance is smaller between ring and ring, once ring
The discrepancy in elevation is excessive will to cause oblique bolt not insert smoothly, therefore larger to ring highness change difficulty during assembly.
3) ring, longitudinal joint subtended angle control difficulty are big
The connected mode of oblique bolt is used between section of jurisdiction ring and ring, section of jurisdiction block uses pre-embedded bolt type joint steel box with block
With reference to the type of attachment of lag bolt, adjustable clearance is smaller, easily causes section of jurisdiction fragmentation once section of jurisdiction ring, longitudinal joint subtended angle are excessive and oozes
Leakage, while may cause bind block and middle standing pillar insertion difficulty, has a strong impact on formed pipe tablet quality.
4) middle standing pillar insertion difficulty is big
The more difficult control in gap and correspondence position between upper and lower piece of rectangle section of jurisdiction, easily occurs when middle standing pillar is longitudinally inserted into
Dislocation, deflection, section of jurisdiction fragmentation, anchor ring are uneven, and difficulty of construction is larger.
5) assembled proficiency is poor, assembled speed is slow
Rectangle section of jurisdiction needs 2 single armed ring rotation assembling machines and 1 both arms assembling machine to coordinate assembled, while needing double
Operate assembling machine and mutually tacit agreement coordinates, operating method has significant difference with conventional Dan Yuan, it is therefore desirable to the adaptation of a period of time.
The positioning requirements of rectangular tube slabbing sole piece, the block that binds, block and middle standing pillar are especially high simultaneously, the time that assembled endless tube piece needs
It is longer.
6) stability contorting difficulty is big during assembly
During rectangle pipe sheet assembling, top section of jurisdiction is unilateral fixation, and domain section of jurisdiction is before block insertion of binding
Horizontal boom state, relative to circular cross-section section of jurisdiction, rectangle section of jurisdiction keeps shape more difficult during assembly, stability contorting difficulty
Greatly.

Good section of jurisdiction Forming Quality, spy is assembled suitable with the section of jurisdiction F that binds, upper T-shaped section of jurisdiction B of the invention and column section of jurisdiction C using two kinds
The different pipe sheet assembling method of sequence, carries out contrast test, and obtain following correction data：
Some fissure of displacement pipe sheet assembling quality controls of the assembling method of fissure of displacement rectangular shield section of jurisdiction of the present invention have been also listed below
The measuring method of method processed, fissure of displacement pipe sheet assembling quality control index and fissure of displacement pipe sheet assembling quality control index.
1st, fissure of displacement pipe sheet assembling method of quality control：
1. before pipe sheet assembling, shield tail squeeze must be cleaned out, and the inside can not have section of jurisdiction fragmentation or finger stone, in order to avoid make to fall
When sole piece is assembled, it is impossible to make it equal with upper endless tube piece anchor ring；
When 2. binding block F blocks with B2 block pipe sheet assemblings, check the waterstop of section of jurisdiction whether there is the phenomenon come off, in order to avoid in section of jurisdiction
Translated into when assembled outside groove, make not closely connected with the anchor ring of previous ring, cause the percolating water phenomenon of section of jurisdiction；
3. check whether bind block F blocks and the anchor ring of B2 blocks section of jurisdiction are smooth, if out-of-flatness, wedge is pasted using use in time
Son, the correction of section of jurisdiction is carried out to it；Pasting for chock is typically pasted with staged, the pasting of chock be difficult it is blocked up, in order to avoid
Section of jurisdiction is produced crack, influence tunnel quality；
4. block B1 blocks section of jurisdiction is descended to belong to first piece of positioning section of jurisdiction, its assembled quality will can directly influence domain pipe sheet assembling quality
And its relative position with shield, it can especially influence the assembly of center pillar C blocks.So, except ensureing it with front ring section of jurisdiction without marking time, occupy
Middle assembly etc. typically requires outer, also should ensure that its perpendicularity (level, two directions in longitudinal direction) with tunnel axis；
5. at the end of upper block B2 block pipe sheet assemblings, the segment bolt close to upper piece side of B2 blocks section of jurisdiction two should not be tightened, and be easy to
Adjustment up and down when column is assembled；
6. jack should accordingly retract by the order of segment assembly., can in the case where section of jurisdiction screw-socket aligns when assembled
Some jack corresponding to the section of jurisdiction are drawn close as needed in order to assembly；
7. jack is drawn close in time after assembly is good, prevents shield from retreating；
8. anchor ring flatness：The ring that must think highly of oneself is done, and by ring inspection, marking time for adjacent block section of jurisdiction should be less than 4mm；
9. anchor ring advanced argument is controlled：Inspect periodically anchor ring advanced argument, the moment ensures section of jurisdiction domain anchor ring and tunnel axis
Perpendicularity；
10. adjacent ring highness change：The size of the high residual quantity of adjacent ring directly influences the quality and tunnel for building up tunnel axis
Useful area, it is therefore necessary to the strict control ring discrepancy in elevation.The adjacent ring section of jurisdiction discrepancy in elevation≤4mm；
Vertical, ring bolt connection：There is vertical, ring bolt connection cyclic section of jurisdiction, and tight ness rating that it is connected is by direct shadow
Ring the overall performance and quality to tunnel.Therefore vertical, ring bolt should be tightened in time after terminating per ring assembly, promoting next ring
When, longitudinal bolt should be tightened up in the presence of the power of jack top.Released as endless tube piece after vehicle frame, it is necessary to tighten up vertical, ring again
To bolt；
The control in tunnel footpath anyhow：When assembled per ring, the footpath anyhow in tunnel should be measured, underproof timely correction is opened
Use section of jurisdiction stabilizing mechanism, it is ensured that cyclic tunnel cross sectional shape, anyhow footpath variable quantity should be less than 0.2%D (D be tunnel anyhow
Footpath).
2nd, fissure of displacement pipe sheet assembling quality control index：
1. footpath anyhow：Anyhow footpath is an important indicator of shaped tunnel stability, and horizontal duck's egg often occurs in circular tunnel
Or the situation of perpendicular duck's egg, footpath change is more complicated anyhow during class rectangle pipe sheet assembling, and local location is likely to occur footpath change anyhow
Small, local location is likely to occur footpath anyhow and becomes big.
2. the ring discrepancy in elevation and seam joint open：The section of jurisdiction ring discrepancy in elevation and seam joint open are reflection tunnel total quality and stability
Another important indicator.The ring discrepancy in elevation crosses conference so that longitudinal bolt is acted on by shearing force for a long time, is easily deformed, and influences
The overall stability in tunnel.Segment joint joint open is excessive easily to cause section of jurisdiction fragmentation and seepage, at the same may cause to bind block and
Middle standing pillar insertion is difficult, has a strong impact on formed pipe tablet quality.
3. section of jurisdiction rotates：Larger rotation once occurs perpendicular to axis direction for section of jurisdiction, it will cause section of jurisdiction gap of the shield tail not
, assembly and the cyclic tunnel quality of follow-up section of jurisdiction are had a strong impact on.
4. section of jurisdiction waterproof：Section of jurisdiction waterproof is mainly made up of itself waterproof and seam waterproof.During pipe sheet assembling once
Destruction is produced to section of jurisdiction waterproof, it would be possible to cause section of jurisdiction percolating water.
3rd, the measuring method of fissure of displacement pipe sheet assembling quality control index：
1. section of jurisdiction rotates：The left and right discrepancy in elevation of upper endless tube piece is measured by survey crew before pipe sheet assembling, water is used
Object staff is placed in bottomed piece of centre；If it is high to measure the left side, then next bottomed piece of ring in assembly it is corresponding to
The right side rotates, and finally makes bottomed piece between two parties and two ends are almost just the same；Per an assembled ring, survey crew must be to bottomed
The ring discrepancy in elevation of block is measured.
2. section of jurisdiction footpath anyhow：In order to monitor Lining Ring deformation during section of jurisdiction is shifted into, set up certain on section of jurisdiction
