In order to illustrate that the assembling method of fissure of displacement rectangular shield section of jurisdiction of the present invention has higher assembled efficiency and good section of jurisdiction Forming Quality better, the pipe sheet assembling method that special employing two kinds is different from the assembled order of the section of jurisdiction F that binds of the present invention, upper T-shaped section of jurisdiction B and column section of jurisdiction C, carry out contrast test, and obtain following correction data:
Below the measuring method of some fissure of displacement pipe sheet assembling method of quality control of the assembling method of fissure of displacement rectangular shield section of jurisdiction of the present invention, fissure of displacement pipe sheet assembling quality control index and fissure of displacement pipe sheet assembling quality control index is also listed.
1, fissure of displacement pipe sheet assembling method of quality control:
1. before pipe sheet assembling, the squeeze of shield tail must be cleaned out, and can not there be the cracked or finger stone in section of jurisdiction the inside, so as not to make bottomed piece assembled time, it cannot be made equal with a upper endless tube sheet anchor ring;
2. bind block F block and B2 block pipe sheet assembling time, check that the waterstop of section of jurisdiction is with or without the phenomenon come off, in order to avoid translate into outside groove when pipe sheet assembling, makes with the anchor ring of last ring not closely connected, causes the percolating water phenomenon of section of jurisdiction;
3. check that whether the anchor ring of bind block F block and B2 block section of jurisdiction is smooth, if out-of-flatness, application adopts in time and pastes chock, it is carried out to the correction of section of jurisdiction; Pasting of chock is generally pasted with staged, and pasting of chock is not easily blocked up, in order to avoid make generation crack, section of jurisdiction, affects tunnel quality;
4. descend block B1 block section of jurisdiction to belong to section of jurisdiction, first piece of location, its assembled quality directly will can affect domain pipe sheet assembling quality and the relative position with shield structure thereof, especially can affect the assembled of center pillar C block.So, except guarantee its with front endless tube sheet without marking time, between two parties except the General Requirements such as assembled, the verticality (level, longitudinal direction two directions) of itself and tunnel axis also should be ensured;
5., at the end of going up block B2 block pipe sheet assembling, on next-door neighbour, the segment bolt of side, block B2 block section of jurisdiction two should not be tightened, be convenient to column assembled time adjustment up and down;
6. jack should by the corresponding retraction of the order of segment assembly.Time assembled, when section of jurisdiction screw-socket aligns, some jack corresponding to this section of jurisdiction can be drawn close as required so that assembled;
7. assembled good after draw close jack in time, prevent shield structure from retreating;
8. anchor ring planeness: ring of must thinking highly of oneself is done, and by ring inspection, marking time of adjacent block section of jurisdiction should be less than 4mm;
9. anchor ring advanced argument controls: make regular check on anchor ring advanced argument, and the moment guarantees the verticality of section of jurisdiction domain anchor ring and tunnel axis;
10. adjacent ring highness change: the size of adjacent ring high residual quantity directly has influence on the quality and tunnel useful area of building up tunnel axis, therefore must the strict gate ring discrepancy in elevation.The adjacent ring section of jurisdiction discrepancy in elevation≤4mm;
vertical, hoop bolt connects: become endless tube sheet all to have vertical, hoop bolt connection, its tight ness rating connected will directly have influence on overall performance and the quality in tunnel.Therefore should tightening vertical, hoop bolt in time after every assembled end of ring, when advancing next ring, under the effect of jack top power, longitudinal bolt should be tightened up.After releasing vehicle frame as endless tube sheet, again must tighten up vertical, hoop bolt;
the control in footpath anyhow, tunnel: when every ring is assembled, should measure the footpath anyhow in tunnel, underproof timely correction, enables section of jurisdiction stabilizing mechanism, ensures into ring tunnel cross sectional shape, and footpath variable quantity should be less than 0.2%D (D is the footpath anyhow in tunnel) anyhow.
2, fissure of displacement pipe sheet assembling quality control index:
1. footpath anyhow: footpath is an important indicator of shaped tunnel stability anyhow, often there is the situation of horizontal duck's egg or perpendicular duck's egg in circular tunnel, during class rectangle pipe sheet assembling, footpath changes more complicated anyhow, and local location may occur that footpath diminishes anyhow, and local location may occur that footpath becomes large anyhow.
2. the ring discrepancy in elevation and seam joint open: the section of jurisdiction ring discrepancy in elevation and seam joint open are another important indicators of reflection tunnel total quality and stability.The ring discrepancy in elevation is crossed conference and is made longitudinal bolt for a long time by the effect of shearing force, easily produces distortion, affects the stability of tunnel entirety.Segment joint joint open is excessive easily causes the cracked and seepage in section of jurisdiction, and may cause binding block and middle standing pillar insert difficulty simultaneously, have a strong impact on formed pipe tablet quality.
3. section of jurisdiction rotates: section of jurisdiction once there is larger rotation perpendicular to axis direction, will be caused section of jurisdiction gap of the shield tail uneven, has a strong impact on the assembled of follow-up section of jurisdiction and become ring tunnel quality.
4. section of jurisdiction waterproof: section of jurisdiction waterproof is mainly through self waterproof and seam waterproof composition.Once produce destruction to section of jurisdiction waterproof in pipe sheet assembling process, section of jurisdiction percolating water may be caused.
3, the measuring method of fissure of displacement pipe sheet assembling quality control index:
1. section of jurisdiction rotates: measured by the left and right discrepancy in elevation of survey crew to a upper endless tube sheet before pipe sheet assembling, and the centre in bottomed piece put by use levelling rod; If it is high to measure the left side, so bottomed piece of next ring rotates to the right side accordingly when assembled, and almost height is the same finally to make bottomed piece of placed in the middle and two ends; An often assembled ring, survey crew all must be measured the ring discrepancy in elevation of bottomed piece.
2. footpath anyhow, section of jurisdiction: to be shifted Lining Ring deformation in process to monitor section of jurisdiction, section of jurisdiction is set up the tunnel observation monument of some, understands convergence situation of change.Lateral arrangement 4 point, vertical layout 4 points, in order to monitor section of jurisdiction level, vertical direction caliber deformation.
