Elastic support structure comprise be fixedly connected on installing plate 21 orienting sleeve 31, be slidably socketed in orienting sleeve 31 and contact at adjustable plate 22 fore-set 32, be located at spring 33 between fore-set 32 and orienting sleeve 31.
Side-play amount adjusting mechanism comprises substrate 41, be fixedly connected on installing plate 21 and be rotationally connected with substrate 41 adjustable column 42, be fixedly connected on substrate 41 and there is activity space 431 regulating block 43, be fixedly connected on adjustable column 42 and stretch into activity space 431 motion bar 44, be threadedly connected to regulating block 43 and one end drives motion bar 44 to be active in the second screw rod 45 of activity space 431; Second screw rod 45 has two, lays respectively at the both sides of regulating block 43, and contacts at the respective side of motion bar 44 respectively.
Substrate 41 is provided with fixed sturcture; Fixed sturcture comprises the two clamping plates 51 be oppositely arranged; The opposite side of two clamping plate 51 all has groove 511; Two clamping plate 51 realize being fastenedly connected by screw.
Generating laser 1 also should be connected with cable and ballast resistor.
This enforcement laser orientation instrument can be applicable to laser controlling tunneling direction and section, as follows:
1, straight tunnel or tunnel
Laser orientation instrument is after debugging, and face laser facula meets and overlaps or parallel condition with tunnel axis, and consistent with the gradient; Face hot spot point overlaps with tunnel axis, then the hot spot point in arbitrary section is all the center line in tunnel, and the vertical distance of hot spot point and arch camber is definite value.
When constructing setting-out in driving, Laser Power Devices need be opened, laser position is measured and the distance in the center of circle of arching upward from laser light spot messenger wire, obtain the center of circle and draw tunnel facade center line, use setting-out bar can draw the tunnel line of apsides by the center of circle and design radial, measure the vertical distance of the center of circle to excavation base plate, the flat distance of center line to abutment wall can be drawn by center line, thus digging control can be carried out to tunnel.
2, circular curve tunnel or tunnel
In curved tunnel driving, along with the change of tunnel mileage, the flat distance between axis, tunnel and laser beam constantly changes, and will edit offset distance table to instruct tunnel piercing for this reason.
Obtain the method for offset distance: utilize CAD software in a computer, according to drawing curve element, by floor plan design, put laser beam position exhibition figure, every drilling depth d in fact, measure offset distance e value; When laser beam intersects with tunnel axis, for avoiding the generation of mistake, other character representations can be changed into; Because the gradient of laser beam is consistent with road gradient in highway tunnel, therefore high process control is identical with straight tunnel method.
3, vertical curve tunnel or tunnel
In vertical curve tunnel piercing, along with the change of tunnel mileage, the vertical distance between the center of circle, tunnel and laser beam constantly changes, and will edit perpendicular apart from showing to instruct tunnel piercing for this reason; Can keystone be obtained by perpendicular distance, can home position be obtained according to sectional drawing size, thus setting-out is carried out to face; In reality driving, because explosion drilling depth predicted value and actual value have difference, so every drilling depth tier, measure the average departure distance values of vertical curve starting point to face, editor is dynamically perpendicular makes the cumulative errors of drilling depth reduce apart from table, reduces the error of offset distance.
Obtain the method for perpendicular distance: utilize CAD software in a computer, according to drawing vertical curve key element, by design vertical curve figure, design longitudinal diagram, put laser beam position exhibition figure, every drilling depth in fact, measure offset distance value.
