High strength grouting material pouring construction technology Grouting material specification

High strength grouting material high strength grouting material mixing ratio in construction of high strength grouting material manufacturer of high strength grouting material chosen to strictly control the mix proportioning of raw materials strictly when using weighing metering, the blender mixing materials to strengthen the control of high strength grouting material quality inspection, in front of the mixer discharge well slump and workability test, does not conform to specified requirement, are not allowed to enter grouting pump. Mix good grouting construction personnel are strictly prohibited again add tap water increase liquidity. High strength grouting material pump truck parking bays column should be close to the steel reinforced high strength micro expansion grouting material model, in order to better use of the pump pressure casting grouting material. Pump truck before feeding, should advance with the same strength grade of cement mortar moist and lubrication pipe plug. Pump pipe connected to the pump truck, the pillars along the horizontal stiffening plate hole into the bottom of the column, and then on to 500 mm, high strength grouting material pouring to the first layer between the horizontal stiffening plate, from the 500 mm has been pouring grouting material to casting. So, to pouring out. Grouting material for each partition casting after extubation time slowly, in order to prevent grouting material to produce holes, honeycomb. Grouting material in the process of casting, and can carry on the vibrating by vibrating vibrating rod, to ensure the compactness of grouting material. Strength to meet the specification requirements. Casting process, using theodolite observation steel reinforced column model of vertical degree at any time, if found deviation, immediately stop pouring, steel reinforced column model of verticality correct during casting. Grouting materials manufacturers selling grouting materials mixing, a set of standard curing 28 d specimen, lien to test the actual quality of grouting material conformance with specification requirements. High strength grouting material should be continuous casting, and should be on the bottom grouting material before initial setting after a layer of casting, in order to prevent the disturbance has initial setting of grouting material and quality defects. If not due to power outages of continuous casting, it is necessary to take reasonable technical measures, in order to ensure the strength of the grouting material to meet the specification requirements. After completion of grouting material pouring 12 h, covering plastic sheeting for maintenance, maintenance of specimen for 7 d. Grouting material curing after 7 d, the steel reinforced column model down the template, JingJian checker without holes, grouting material surface defects such as honeycomb, ballast-surface. After pouring 28 d of high strength grouting material, the standard curing test specimen to the laboratory, strength meets the requirements. Ultrasonic detection, steel reinforced pillar grouting material various technical indexes meet the specification requirements. Slope roof slope concrete pouring and shuttering slope slope the construction quality of grouting material is a technical problem in construction. , due to the slope gradient is large, grouting material in the process of casting, and vibrating rod vibration due to gravity, grouting material easy to flow down, so there is no guarantee that slope roof slope on the lower thickness, compactness and smoothness of the grouting is also can not meet the requirements. Shandong zibo jade wall building materials co. , LTD. , through the construction practice and exploration for a long time, summed up a set of effective methods to ensure the quality of slope room cant grouting material construction. Specific process is as follows: the erection bracket - Cant stay leveling - Install the insensitive - Adjustment plate bottom insensitive flat - Laying bottom plywood - Reinforcement and scaffold inspection template cant flat - Steel binding - Line pipe installation - Concealed engineering acceptance & amp; Mdas grouting material block a set a few h; The upper template installation fixed - Roof grouting material casting - The upper template removal - The maintenance of grouting material.
