The present application belongs to the field of building construction technology, and particularly relates to a plugging construction method for holes around a through-wall pipe, comprising the following steps: step one, pretreating a sleeve around the through-wall pipe and pre-fixing the through-wall pipe; step two, assembling a formwork around the through-wall pipe; step three, sealing between the periphery of the formwork and the wall; step four, pouring grout between the formwork and the wall; and step five, removing the formwork after the grout is cured to a suitable strength. Compared with the prior art, the present application sets a formwork around the through-wall pipe, seals between the formwork and the wall, and then pours grout between the formwork and the wall, so that the holes around the through-wall pipe are plugged after the grout is solidified, thereby preventing subsequent leakage of the drain pipe.

The application discloses a large-diameter box culvert template self-adaptive installation and dismounting adjustment method and system, and belongs to the technical field of intelligent control of civil construction. The method comprises the following steps: collecting pressure data through hydraulic preloading to solve the initial demolding load; when the load exceeds the threshold value, starting an asymmetric exciter and configuring a phase angle deviation, exciting a traveling wave mode on the template panel to destroy the adsorption stress; through the pressure adjustment execution element, the retracting oil cylinder is rapidly pressurized and depressurized, so that the template reciprocates; after the gap is formed, according to the instantaneous demolding speed fed back by the displacement sensor, a closed-loop adjustment algorithm is run to dynamically adjust the excitation force amplitude and the pulsation frequency until the template completely exits. The system comprises a perception layer, a decision layer and an execution layer. The application can actively release the strong adsorption stress between the template and the concrete, avoid demolding damage, and improve the intelligent level and safety of large-diameter box culvert construction.
