The invention provides a manual multichannel TOFD (time of flight diffraction) scanning frame and belongs to the technical field of machines. The manual multichannel TOFD scanning frame can be used for solving the problems that the existing TOFD scanning frame is inconvenient in operation and scanned data is not accurate enough. The multichannel TOFD scanning frame comprises a total coder, a roller, a pushing handle and a plurality of pairs of probe assemblies as well as a vertical beam and a plurality of cross beams, wherein the probe assemblies are electrically connected with the total coder, the roller and the probe assemblies are arranged on the cross beam, the pushing handle and the total coder are connected above the vertical beam, an alarm and a steering angle instrument are also arranged on the scanning frame, the steering angle instrument is arranged on the vertical beam and is electrically connected with the total coder, and the alarm is electrically connected with the total coder. The multichannel TOFD scanning frame has the advantages that whether the direction of travel of the scanning frame shifts from a desired track or not is detected by virtue of the steering angle instrument, and an alarm is given to inform a scanning worker of adjusting a scanning direction, so that accuracy of defect data obtained by scanning is guaranteed.

The invention discloses a large-size grouting body construction method. The method includes the steps of cleaning, humidification, formwork erecting, mortar production, pouring, maintaining, secondary pouring and the like. According to the method, a galvanized corrugated pipe or a galvanized steel pipe with rib sheets is adopted as a cooling pipe, the area of contact between the cooling pipe and a pouring body is increased, meanwhile, the stress direction is changed, and the total planar stress is changed into stress along the surface arc of the corrugated pipe; part of ice blocks are used for replacing part of water and used for producing mortar in a stirring mode, ice particles absorb hydration heat and gradually melt, the molten ice particles absorb a large amount of hydration heat and are lost through evaporation, temperature is not raised in the process that ice is molten into water, and temperature in the pouring body is further lowered.
