In an embodiment of the present invention, the transportation can be performed in the following manner: during transportation, a proper transportation mode is adopted according to the characteristics of the prefabricated arc blind hole component, and the prefabricated arc blind hole component can be transported in a leaning and standing mode or in a horizontal stacking mode.

When the temporary fixing device is installed, the temporary support system and the temporary fixing measures for fixedly supporting the prefabricated arc blind hole components have enough strength, rigidity and overall stability. In an embodiment of the present invention, the following steps can be performed: after the prefabricated arc blind hole components are in place, the connecting steel bars are moved, the dowel bars are inserted into the first through holes and the second through holes to form a steel bar framework together with the connecting steel bars, after the adjacent arc blind hole components are connected in a matched mode, the grooves form pouring holes with open top ends and closed peripheries, and the pouring holes are used for pouring concrete. And pouring concrete into the pouring holes and the through holes, and filling the through holes to form connecting joints with good performance.

When the upper and lower two parts shell ring are connected, the shell ring is hoisted, the third through hole of the upper component is aligned to the dowel bar position exposed by the lower component and then placed and supported for fixing, then concrete is poured into the third through hole, the post-cast part is compact due to sufficient vibration, and the upper and lower components are connected into a whole.

The utility model discloses a blind hole arc component of muscle has not gone out, has solved the above-mentioned problem that the muscle component exists, has higher transportation and assembly efficiency. The connecting steel bars are in two states, the connecting steel bars are hidden in the transverse holes during transportation and hoisting, and the prefabricated parts move to stretch out to cross the connecting joints after being in place so as to connect the adjacent arc-shaped parts. In terms of structure, the steel bars can be prevented from rusting and bending and twisting, and the influence caused by staggered overlapping of the steel bars is avoided; during construction, the connecting steel bars are quickly installed, and the construction time is saved; in addition, with the structure, the on-site concrete pouring amount can be reduced.

Furthermore, the utility model discloses a prefabricated arc blind hole component has standardized side structure, and prefabricated component's template is standardized, is favorable to promoting batch production level, does benefit to and adopts the founding mould production, is showing and promotes production efficiency, makes the component can become batch production, saves manufacturing cost, reduces mould's the stand and sells.
