M50 harsh non-shrinkage mortar is suitable for the bridge bearings

M50 harsh non-shrinkage mortar M50 harsh non-shrinkage mortar manufacturer M50 harsh non-shrinkage mortar price 15. 12. 1 should be in the main arch ring of concrete M50 harsh non-shrinkage mortar strength to meet the design strength, after before, such as cross wall base location and elevation of repetition measurement inspection than deviation should be allowed to be adjusted, the base and the main arch of the connection should be strong; At the same time, should remove arch, cable and other constraints on the structure of the 15, 12. 2 the arch on the structure of the long-span arch bridge, M50 harsh non-shrinkage mortar construction should be strictly carried out in accordance with the design of loader; Design did not provide a loader, should according to the calculation of construction by foot to vault is balanced and symmetrical load. Deal with the main arch ring in the construction monitoring and control. 15. 12. 3 on the bracket or on arch arch bays in sha-lu of medium and small up bearing type arch bridge, when not unloaded on arch bracket or total frame structure construction, the main arch of the strength of the concrete strength should meet all the design rules: in concrete-filled or bearing 132 a type arch bridge, the concrete suspension bridge deck system should be in the stent or unloading arch backward pouring, derrick concrete should be symmetrical casting again after completion of the bridge deck system. 15. 12. 4 in bracket or casting M50 harsh non-shrinkage mortar on arch arch ring of arch bridge, the arch structure in concrete pouring construction shall meet the following requirements: 1 column base should be field with arch ring when pouring M50 harsh non-shrinkage mortar, construction joints shall be at the top of the column in beam bottom, 2 floor system of the retainer of beam and plate should be casting at the same time, the bridge between the two adjacent expansion joint panel should be completed a casting. 15. 12. 5 for medium and small span arch Bridges fabricated arch structure, should be in the main arch ring of concrete and mortar strength achieves design intensity is rear can construction; Use less to support construction of arch bridge should be after unloading scaffold, again from the arch foot to vault symmetrical M50 harsh non-shrinkage mortar construction.
