(9), steel box-girder assembling quality inspection:
Assembling inspection, emphasis inspection are directly often carried out on jig frame special after the completion of wheel beam section integral assembly welding:Bridge is longitudinally linear, Beam section longitudinal direction accumulation length, port match situation between distortion, sections;
1., bridge totality linear dimension inspection:
Linear inspection:Bridge linear inspection detects each beam section two ends diaphragm plate on the basis of the theoretical absolute altitude at longitudinal centre line The actual elevation value at place, checks the side sway of pre-splicing beam section center line while checking linear;
Beam section distortion is checked:It is by checking the left and right absolute altitude value at the diaphragm plate of each beam section two ends, judging the horizontal of each beam section State and distorting event;
Beam length and the position detection of guy anchor solid point:Center is used as the accumulation length for checking each beam section at beam section suspension centre dividing plate, it is determined that The compensation rate of follow-up beam section;
2., between beam section port matching precision inspection:
In addition to bridge totality linear dimension is checked, it is necessary to check the match condition of connecting elements between beam section;
Port connection answers emphasis to check deck-molding at side web, median ventral plate between beam section;
Adjacent median ventral plate, side web contraposition deviation;The flat bevelled halving corner deviation of base plate, edges of boards unfitness of butt joint, top board longitudinal rib misalignment;

The gap of steel box girder segment interface must strictly control, and excessive gap can increase welding contracted quantity, and gap is too small Easily cause weld seam and melt impermeable;
Specify that reasonable groove gap is a key factor for ensureing steel box-girder quality, this bridge gauge determines sections interface gaps minimum value It is 6mm, its tolerance scope is 0~+4mm, other key elements of sections connection must all be launched with this;
Gap positioning process plate is taken in overall package, it is ensured that gap size;
Several gap anchor points are determined at top, base plate, for clearance inspection;
If gap is less than setting, should be modified;After amendment is finished, check whether the unfitness of butt joint of edges of boards is less than 1mm, most Afterwards by all data Ji Lu check tables;
4., assembling check measurement requirement:
The absolute altitude of each beam section, the measurement of length significant dimensions, should avoid sun exposure influence, and record environment temperature;
Measurement steel band or gauge should deposited with detected work before with condition, make the two temperature consistent, steel band or Steel ruler is periodically examined and determine;
Measurement spirit level, theodolite, instrument all measurers are both needed to be examined and determine through two grades of metrological services;Should be calibrated before, and pressed It is required that using;
Operating personnel should take appointment with certificate through special training, and implementation determines people and determines instrumentation;
The pulling force of steel ruler range finding tensiometer used should meet the regulation of steel ruler specification;
Measurement coordinate system system when assembled using moulding bed region carries out Site Detection.
