Construction method for installation and positioning of embedded rubber water-stop belt

Abstract

The invention discloses a construction method for installation and positioning of an embedded rubber water-stop belt. A rubber water-stop belt lower combination mould plate and a rubber water-stop belt upper combination mould plate are used, the rubber water-stop belt lower combination mould plate is in butt joint with the lower part of a main keel for preliminary tightening and fixing, the embedded rubber water-stop belt is placed on the rubber water-stop belt lower combination mould plate , a middle hollow circular ring of the embedded rubber water-stop belt is placed flat in a lower seat groove of the water-stop belt, and the rubber water-stop belt upper combination mould plate is in butt joint with the upper part of the main keel for preliminary tightening; and meanwhile an upper seatgroove of the water-stop belt is closed on the middle hollow circular ring of the embedded rubber water-stop belt in a covered mode, the mould plates are then overall reinforced, a pouring mould is erected outside a reinforcement cage, and concrete is poured. According to the construction method for installation and positioning of the embedded rubber water-stop belt, the position of the embedded rubber water-stop belt is fixed through combination of joint sealing materials of a deformation joint and traditional mould plates, the fact that the middle hollow circular ring of the embedded rubberwater-stop belt coincides with the center line of the deformation joint can be ensured all the time.

Description

technical field [0001] The invention relates to the field of corridor engineering construction, in particular to a construction method for installing and positioning a mid-buried rubber waterstop at an expansion joint of an underground corridor of a nuclear power plant. Background technique [0002] The mid-buried rubber waterstop is pre-buried in the construction joints and expansion joints (hereinafter collectively referred to as deformation joints) and integrated with the concrete during concrete pouring, and plays the role of water stop by extending the seepage path, which can effectively prevent Water seepage and leakage at the deformation joints of structures, and play the role of effective fastening and sealing, vibration damping and buffering, so as to ensure the waterproof and anti-leakage requirements of engineering structures. When the buried rubber waterstop stretches and pulls apart in the deformation joint, the geometric deformation first occurs, and then the s...

Problems solved by technology

When pouring concrete, the buried rubber waterstop is prone to shift, causing the hollow ring in the middle of the buried rubber waterstop to deviate from the center line of the deformation joint, that is, to shorten on one side. When the deformation joint is deformed and subjected to water pressure, The ability of the buried rubber waterstop to resist external forces is greatly reduced, and in severe cases, it will cause water leakage instead of water, which will cause great hidden dangers to the use of buildings and increase the cost of operation and maintenance.
