Building technology co. , LTD provides cross river bridge material bearing mortar

Cross river bridge material bearing mortar 1, according to the characteristics of this bridge, steel box girder hoisting need to set up a large number of temporary support, due to the heavier components and support within the river channel, demand is high, to the stability of the support and support infrastructure support set is difficult; Solution: in the steel box girder set just below the steel support, support infrastructure using bored pile or extension, steel support through top steel Liang Liancheng whole, improve the overall stability, to meet the demand of the stiffening girder construction of supporting system. 2, steel box girder with subsection installation, to meet the requirements of the whole bridge linear, requires accurate measurement of each adjustment, high linear adjusting difficulty; Solution: detailed measurement scheme, for each installation section for precise positioning, and according to the design of the linear adjustment bridge deck elevation and mortar with bearing level, to ensure that the entire bridge line. 3, the whole construction site, located within the river channel, how to effectively flood prevention and drainage should be considered; Solutions: temporary support basis except near the bridge tower adopt bearing grouting material piles, in the middle of the river 50 m within the scope of erection of the steel trestle, as a general situation of construction road and drainage channels; When meet large floods, within the scope of the north of steel trestle 50 m digging construction cofferdam drainage.
