Bridge engineering construction: how to deal with button bowl full framing construction base
Before support build-up of foundation treatment, the scope of the erection of scaffold using mechanical field leveling roller compaction, according to the actual geological conditions of the construction site, the reasonable filling thickness, compaction, hierarchical requirements after compaction of 90% or more, on the top surface laid 15 cm thick layer of cement stone chips stability for hardening treatment. Width of foundation treatment within the scope of a certain slope, slope lateral excavation drainage, to facilitate drainage. And water stability layer before dealing with the foundation of foundation bearing capacity test, to ensure that the foundation bearing capacity satisfies the requirement of stress. Horizontal board is put above, size to 4 cm x 15 cm x 200 cm, board to close post with the ground, if you have any dangling pad application of cement mortar.
Foundation treatment steps, poling edge should not be less than 0.6 m from the steps, and the steps edge should be earmarked for flaky masonry. Close to the pier column roller compaction not easily, should adopt the method of artificial solid guarantee its compaction is achieved.
