Embodiment 1

[0031] Such as figure 1 , figure 2 , image 3 , Figure 4 As shown in the figure, a construction technology of pre-embedded steel edge waterstop and waterstop steel plate reinforcement for comprehensive pipe gallery includes steps:

[0032] 1) At the bottom of the water-stop steel plate 1 on the side wall, set a positioning rib 3 horizontally at intervals of 1.5-2.5 meters to support the water-stop steel plate 1, and the positioning rib 3 is welded and fixed on the steel skeleton to prevent the water-stop steel plate 1 from longitudinally shifting.

[0033] 2) Install the waterproof steel plate 1.

[0034] 3) Install several pairs of U-shaped reinforcement bars 2 on the left and right sides of the water-stop steel plate 1, and squeeze the water-stop steel plate 1 tightly; The water-stop steel plate 1 and the two side parts 21 of the U-shaped reinforced steel bar 2 are welded to the steel bar skeleton to prevent the lateral deviation of the water-stop steel plate 1; the si...

Abstract

The invention discloses a construction technology for pre-embedded steel edge waterstops and waterstop steel plates in a comprehensive pipe gallery, belonging to the field of construction engineering. In the present invention, several positioning ribs are arranged horizontally at the bottom of the water-stop steel plate; several pairs of reinforcement bars are also installed on the left and right sides of the water-stop steel plate to squeeze the water-stop steel plate, preventing the vertical and lateral deviation of the water-stop steel plate, thus greatly The displacement deviation of the water-stop steel plate is greatly reduced, the accuracy and pass rate of the pre-embedded material of the water-stop steel plate are significantly improved, the construction efficiency is improved and the construction quality is guaranteed to meet the specification requirements. The present invention adopts the double-layer positioning box to reinforce the steel edge waterstop as a whole, which increases the reinforcement area of ​​the positioning box and the waterstop, and avoids the reinforcement of the steel edge waterstop in the prior art, which will cause the steel edge waterstop to be in the concrete. The deviation occurs during vibration, which significantly improves the accuracy and qualification rate of the pre-embedded materials of the steel edge waterstop, improves the construction efficiency, and ensures the construction quality to meet the specification requirements.

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...
