Summary of the invention
The purpose of this utility model is to provide a kind of good sealing property, simple in structure that has, handling ease, and the single steel strand tie-rod rope of easy construction is at the water-tight device of entrance, anchorage zone, to solve the above-mentioned technical problem that existing water-tight device exists.
The technical scheme that addresses the above problem is: a kind of single steel strand tie-rod rope is at the water-tight device of entrance, anchorage zone, comprises gland, baffle plate, steel cylinder, is positioned at the pre-embedded steel slab of entrance, anchorage zone and is embedded in the service sleeve of abut;
Described gland is the tubular lid that has interior stepped hole and internal thread;
Be useful on the through hole that passes steel strand on described baffle plate, the pre-embedded steel slab respectively;
Described service sleeve is to be enclosed within the outer tubing of single steel strand, and tubing mouth of pipe endoporus is tubaeform;
There is external screw thread one end end of steel cylinder, interior step is arranged in it, the other end of steel cylinder is welded on the pre-embedded steel slab, baffle plate is positioned on the step of steel cylinder end, gland and steel cylinder screw and tighten steel cylinder, are perfused with encapsulant in the cavity of being made up of baffle plate, steel cylinder, pre-embedded steel slab, service sleeve and steel strand rope.
Its further technical scheme is: the described outer tubing of single steel strand that is enclosed within comprises PE pipe, pvc pipe or steel pipe.
Described encapsulant is Polyurethane blowing agent or the encapsulant that can combine closely with the steel strand rope.
The water-tight device of single steel strand tie-rod rope in the entrance, anchorage zone of the utility model changed the form of structure that original whole bundle single steel strand tie-rod drag-line shares pre-pipe laying, the integral built-in pipe that whole bundle single steel strand tie-rod rope is shared changes single service sleeve into, entrance at single service sleeve arranges water-tight device again, is perfused with encapsulant 5 in the cavity being made up of baffle plate 2, steel cylinder 3, pre-embedded steel slab 6, service sleeve 7 and steel strand rope 4; Therefore, the utility model single steel strand tie-rod rope is compared in the water-tight device structure of entrance, anchorage zone with existing single steel strand tie-rod rope at the water-tight device of entrance, anchorage zone, and the beneficial effect that has is:
1. have good sealing property, good springiness, compliance is strong, also can seal even vibration takes place cable body, and very big practicality is arranged.
2. simple in structure, handling ease, easy construction is conducive to the construction of steel strand tie-rod drag-line engineering.
3. because the water-tight device good water-proof effect of the utility model reduces the corrosion of steel strand tie-rod drag-line, will improve tie-rod application life greatly, produce good economic and social benefits.
Be described further at the technical characterictic of the water-tight device of entrance, anchorage zone below in conjunction with the single steel strand tie-rod rope of drawings and Examples to the utility model.
