Method for building post-pouring expansion reinforcing band of wallboard of underground structure
The invention provides a method for building a post-pouring expansion reinforcing band of a wallboard of an underground structure. The method comprises the following steps: step one, according to the size of the wallboard, determining the form and the arrangement mode of the expansion reinforcing band; determining the kind and the dosage of an expanding agent; step two, manufacturing a concave fixed plate of a box type fixed structure; step three, determining the position of the post-pouring expansion reinforcing band, and arranging the box type fixed structure; step four, arranging prestressed steel bars; step five, tying the steel bars and prestressed steel bar embedded pipes; step six, pouring concrete; step seven, tensioning the prestressed steel bars and grouting the embedded pipes. The method overcomes the defects that the prior art does not define a method for determining the kind and dosage of the expanding agent, can not effectively isolate wallboard concrete from post-pouring expansion reinforcing band concrete, is difficult and complex in construction, cannot adapt to the high waterproof requirement and is limited in the application of the post-pouring expansion reinforcing band. The method realizes the design and construction of the waterproof crack-resisting structure of the underground structure and effectively prevents concrete from water seepage and cracking.
