Filling grouting material base frame

3 how filling grouting filling grouting material construction. 10 perfusion grouting material the first layer should be continued perfusion, write height should be 30 ~ 40 mm below the bottom of the template appearance, along the slope flow backward, during which level of mortar stick to perfusion with metal belt. Usually in the first layer filling over the next 20 to 40 minutes, shall be promptly perfusion to the second floor. The second layer should also successive perfusion, slit overflow, or until the mortar from export and make it into the grouting material overflow sprue gate. 3. 11 cement block began to care care within 3 days of the start of the cement block, its temperature contains template temperature should be between 10 to 35 ℃. Exposed to the air in the sprue gate and the mortar on the spillway, use of thin plastic sheet or pot tin plate cut off. Cement block around the beginning of a concrete foundation maintenance period, also can be the method that use water spray to care. 3. Removal of base frame in accordance with the care to the request, the third day after grouting, loosen the backplane anchor bolt and nut, swing frame. 3. Maintenance of the hardened cement block 3. 13. 1 from the anchor bolt nut after remove the base frame, should use wet cloth to the mortar pad, then, should be in the mortar pad with the brush next to each twice maintenance mixture on the finish. 3. 13. 2 should be from the slit export overflow spillway or has solidified mortar to clear clean. 3. 13. 3 ends after the above process, cement block and concrete foundation should use water spray method make it wet, and the entire cement block protection should use wet cloth to package. Keep an eye on the mortar pad material in this time period is not promised to accept any irregular load. 3. 14 to see cement block and the space between the base frame view cement block and the space between the base frame, with the aid of the touch of red lead to end. The underside alter good red lead frame is located on the cement block, within the scope of the promise of mobile, by moving around to see the pedestal base with the touch of cement block condition. Touch the area of the request is not less than 80%, the cement block touch 0 appearance gap with the base frame. 05 mm feeler does not enter the, part into depth and width are not beyond a quarter of the length. 3. 15 to adjust the level of the base frame touch area to reach request, will base bolted together. Then, use as adjusting the level of the base frame. Promised level error is at 0 per meter. 02 mm within, and the level of error control the accumulated value 0. 13 mm or less. 4 cement block making attention to item 4. 1 before grouting material casting, it is necessary to make the appearance fully wet concrete foundation, or pouring good cement block is simple in loose posted at present and concrete foundation. 4. 2 must pay attention to irrigation maintenance in the future. Pay special attention to prevent the wind effects on cement block. End the practice proved: pouring in the future, should be promptly to wind and the cement block, or the appearance of cement block will present the scene of a segregation resulted in cement appearance presents the defects, such as bubbles, fall, disability, etc. 4. 3 grouting material mixing, pouring before it is necessary to wait for a period of time so that bubbles completely free, or generated by the cement block pores, pits probability will rise greatly. 4. 4 in water connecting tool measurement datum base frame and reference frame, the relative elevation of measurement it is necessary to investigate the connecting pipe between the two cups before accumulation has air bubbles inside, if there are air bubbles, it is necessary to eliminate to bubble talents after measurement, otherwise there is biggish error measurement results will be. 4. 5 when bearing pedestal elevation before the adjustment, it is necessary to strictly controlled, and the appropriate level should not be high, low or cement block bearing before filling up, in the subsequent steam turbine shaft system for base, may cause low with the presented under the condition of big mouth. At this time in order to eliminate the big mouth, it is necessary to all the high low pressure cylinder, A and B in A, B between the low pressure cylinder pedestal and cement block and A lot of gaskets, greatly increase the workload of device. Conclusion through a certain power plant units 3 and 4, long safe operation, sets the objectives were higher than of the inspection standard and regulations about the good specification, indicating the device technology has its outstanding safe sex, it is worth for using a new type of device technology.
