Strengthening construction process for comprehensive pipe rack pre-embedded steel edge water-stop belt and water-stop steel plate

Abstract

The invention discloses a strengthening construction process for a comprehensive pipe rack pre-embedded steel edge water-stop belt and a water-stop steel plate, and belongs to the field of architectural engineering. The strengthening construction process is characterized in that a plurality of positioning ribs are horizontally arranged on the bottom of the water-stop steel plate, a plurality of pairs of strengthening steel bars are mounted at the left side and the right side of the water-stop steel plate, and the water-stop steel plate is squeezed, so that the water-stop steel plate is prevented from longitudinally shifting and transversely shifting, and therefore, displacement deviation of the water-stop steel plate is greatly reduced, an accuracy rate and a qualification rate of the water-stop steel plate pre-embedding material are remarkably increased, construction efficiency is improved, construction quality is guaranteed, and specifications are met. According to the strengtheningconstruction process disclosed by the invention, a double-layer positioning box is adopted to integrally oppositely pull and strengthen the steel edge water-stop belt, so that a strengthening area between the positioning box and the water-stop belt is increased, a condition that the steel edge water-stop belt deviates when the concrete is vibrated as a result of strengthening the steel edge water-stop belt in the prior art is avoided, the accuracy rate and the qualification rate of the steel edge water-stop belt pre-embedding material are remarkably increased, construction efficiency is improved, construction quality is guaranteed, and the specifications are met.

Description

technical field [0001] The invention relates to the field of construction engineering, in particular to a construction technology for pre-embedded steel edge waterstops and waterstop steel plates in a comprehensive pipe gallery. Background technique [0002] At present, in the construction of the comprehensive pipe gallery, the daily reinforcement of the steel edge waterstop is reinforced by separate upper and lower single-layer formwork, and the vertical position is only clamped by the upper and lower formwork. The middle hollow ring of the side waterstop does not coincide with the center line of the deformation joint, and the large displacement deviation may cause deformation of the mid-buried steel side waterstop. [0003] Moreover, in the current construction of the comprehensive pipe gallery, the water-stop steel plate on the side wall is fixed by spot welding. If the spot welding is too heavy, it will easily damage the steel plate. If the spot welding is slightly light...
