High-speed rail bridge with prestressed precast beam field pipeline pressure slurry have what performance

Prestressed pipe pressure prestressed pipe pressure prestressed pipe pulp price pressure slurry paste manufacturer should be the special construction design platform, prestressed pipe pressure slurry and shall meet the following requirements: 1, the string construction platform and steel tube column position deviation should be within 300 m, slope should be within 1% of 1 platform top face should level off, the joint should be fixed. The provisions of section 3: using the liners erection of the steel construction of drilling platform, in addition to outside force of the steel armor Jane to check the seaborne still should keep its position accurately, interconnected slope stability, shall not exceed the allowable deviation. 3 platform is located in a river or water scouring, necessary measures should be taken for its basic ice and debris impact protection is located in the river, the prestressed slurry pipeline pressure should be set up temporary anti-collision facilities, to ensure the stability of platform during construction. 4 raised platform in the navigable waters, besides should be temporary measures, it is obvious pass sign should be set up five water rescue facilities on the construction of the platform shall be forever. Grand XiaoXuan floating flat and ship according to the current situation, the platform scale for the load determining, all ships shall be cast in four direction positioning, and should be in the construction period of the bore log its monitoring, control the accuracy of buy every day. Protection of Jane's set shall meet the following requirements take-easy USES the steel plate. Or watershed in the place of the island to protect Jane, its diameter should be the diameter of at least 2000 liners in circular section shape and the original can - shape: under the sink in the water to machinery of the liners, its inner diameter and wall thickness of the size, should be based on the plane of the guard, 'degree of partial た ド degrees and requirements for sure: participate in seaborne force protection, Jane, the inner diameter, wall thickness, and shall comply with the design of 2 guard Jane long in setting, except as otherwise provided in the design, Jane protection center and center position deviation should be no greater than 50 m, protect Jane in straight direction tilt LiaoDu should not be greater than 1 to protect Jane, in water base plane position deviation can be, but should not be greater than 80 mm. , built in the early and island set up to protect Jane, can use pit buried to the measured location, and protect and lateral around the bottom of Jane's viscousness should be adopted and backfill and layered poor compaction, the mouth for bottom protection from loss of mud; Sink in the water when setting protect Jane, appropriate USES guide frame positioning, prestressed pipe pressure slurry and effective measures should be taken to ensure the accurate plane position, slope, and Jane extension joint welding quality, welding joints of the wall should be no protrusions, and should be resistant to pull, pressure, no leakage. Om; 0 m and shall be stable hole head measures during construction; More than 0 md. 4 to protect Jane embedment depth in the dry land or build island place appropriate for 2-4 m, in the water, or special circumstances should according to the design requirements or pile of hydrology, geology determined by way of calculation. 5 m, and the mission to prevent riverbed in excessive erosion during the construction of the protective measures. Drilling construction shall meet the following requirements 1 drill selection should be based on the aperture, hole depth, pile located in hydrological and geological conditions, construction conditions on environmental factors such as comprehensive, prestressed pipe pressure slurry drilling rig and drilling methods should be chosen to meet the requirements of construction quality and construction safety.
