Embodiment Construction

[0015] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0016] The anti-seepage structure applied to concrete pressure-resistant containers of the present invention comprises a concrete wall 1, steel embedded parts 2, steel plates 3 and FRP coating 4; the outermost layer of the anti-seepage structure is a concrete wall 1, made of steel The embedded part 2 is placed in the concrete wall 1, and the steel embedded part 2 is welded to the prestressed reinforcement in the concrete. The structure adjacent to the concrete wall 1 is a steel plate 3, and the steel plate 3 is processed with steel The welding hole corresponding to the part of the embedded part 2, the steel plate 3 is welded with the steel embedded part 2 through the welding hole on it, so that the steel plate 3 is closely attached to the concrete wall, and the outer layer of the steel plate 3 is evenly coated with FRP coating 4.

Abstract

The invention relates to an impermeable structure applied to a concrete pressure container, which belongs to the technical field of solid engine test, and comprises a concrete wall, steel embedded parts, a steel plate and a glass fiber reinforced plastic coating, wherein the concrete wall is arranged on the outermost layer of the impermeable structure, the steel embedded parts are arranged in the concrete wall, the steel embedded parts are connected with a prestressed steel bar in concrete, the steel plate is adjacent to the concrete wall and is closely attached to the concrete wall after being welded with the steel embedded parts, and the glass fiber reinforced plastic coating is uniformly coated on the outer layer of the steel plate. The impermeable structure is simple in construction process, easy to realize, applicable to the concrete pressure container under the pressure lower than 0.4MPa, and water in the concrete pressure container can be prevented from permeating outwards via the wall.

Description

technical field [0001] The invention relates to an anti-seepage structure, in particular to an anti-seepage structure applied to concrete pressure-resistant containers, and belongs to the technical field of pressure-resistant and anti-seepage structures. Background technique [0002] When the solid rocket motor works underwater, there are great differences in the ignition and starting characteristics and working performance of the engine and the work on land. Therefore, the underwater test is an important means to evaluate the performance of the underwater working solid rocket motor. At present, small-scale solid engine tests of technical research nature are mostly carried out in smaller-sized pressure vessels, and medium and large-scale solid engine underwater tests are often carried out in inland lakes or seas where natural conditions are more suitable. The gas pressurized underwater test pressure vessel is more suitable for the technical research of small and medium-size...
