Description
?
[technical field]
The present invention relates to the tunnel construction field, be specifically related to a kind of tunnel hand hole joint bar draw-off gear and Hubbing method thereof.
[background technology]
Known, to wear yellow tunnel and adopt the wholecircle Section Design, the internal diameter of tunnel is 7.0m, the external diameter of tunnel is 8.7m; Tunnel lining is by inside and outside two-layer the composition, and is outer by 7 reinforced concrete prefabricated section of jurisdiction staggered joint erections, the thick 40cm in its section of jurisdiction; Ring width 1.6m owing to wear the hydraulic pressure that yellow tunnel will bear maximum 0.67MPa, presses the structural requirement that holds water in order to satisfy to have; After accomplishing the outer lining pipe sheet assembling, in shield structure tunnel, designed inner lining structure again, inner lining structure is a posttension daraf(reciprocal of farad) PSC; Tunnel lining adopts the C40.W12.F200 PSC, and thick 45cm, standard section length are 9.6m; In order to verify folding degree and the stressing conditions under 0.67Mpa hydraulic pressure between section of jurisdiction outer lining and the concrete lining, hand hole adopts the high-grade concrete backfill in the tunnel section of jurisdiction, arranges pre-buried joint bar in the hand hole of section of jurisdiction simultaneously, is connected with the tunnel lining steel reinforcement cage.
And in order to guarantee that tunnel can reach designing requirement; The workmen tends in work progress the pre-buried hand hole joint bar pull-out test of sampling; And then whether the backfill concrete can satisfy the joint bar anchoring effect in the checking hand, because the section of jurisdiction hand hole is many in the tunnel, and the joint bar anchorage depth is little; So joint bar pull-out test process is had strict requirement, and existing test method is:
Method one: through making a steel plate, adopt the lifting jack of artificial support fixation anchor pole drawing appearance, the direction of regulating lifting jack and anchor pole or other pre-buried rod member again, direction is carried out drawing after regulating unanimity again.This kind method is carried out drawing, and construction is difficulty comparatively, when construction, need be equipped with several personnel and carry out supporting steel plate; After anchor pole is packed lifting jack into, vertical with lifting jack then through regulating steel plate at four jiaos of increases of steel plate cushion block, treat that lifting jack begins drawing after stressed again; In the work progress; Operation easier is big, and anchor pole receives force direction wayward, and speed of application is slow;
Method two: through the anchor pole installed surface being cut or polishing; After making the anchor pole direction and the installed surface direction being vertical lifting jack is installed again and is carried out drawing, this kind method is favourable for the anchor pole or the pre-buried rod member of preliminary bracing face, but the strict control of construction surface needs that cuts or polish; And it is poor for applicability; The drawing construction more to quantity or building surface must not destroy, this method operating difficulties has destruction to facade and anchorage depth.
Adopt above-mentioned test method to have drawbacks such as inefficiency, complicated operation; Do pull-out test owing to require every standard paragraphs to choose 3 groups of joint bars at the crown position at the trial; Single joint bar design pulling capacity is 86.6KN, and necessary strict guarantee joint bar and anchor pole drawing appearance are on same straight line when pull-out test, and this test drawing amount is big; And anchor pole drawing appearance is difficult for fixing at the trial; Topmost above-mentioned test method influences the normal construction of liner, for this reason, joint bar draw-off gear and Hubbing method improved has just become those skilled in the art's technical barrier anxious to be solved.
