Problems solved by technology

This treatment method cannot effectively solve the problem of water leakage at special construction joints. After the construction is completed, this position is prone to cracks due to the construction of concrete in the later stage, and there is no effective water-stopping measure at the cracks, resulting in serious water leakage and is not suitable for rich water.

Embodiment 1

[0033] Such as Figure 1-Figure 4 As shown, this embodiment provides a waterproof structure using a combined steel-edged rubber waterstop, including a pre-concrete structure 1, a post-concrete structure 4 and a combined steel-edged rubber waterstop 3; the pre-concrete structure 1 and the post-concrete structure Make the positioning connection of the concrete structure 4, and the steel plate groove 2 with the opening facing the rear concrete structure 4 is pre-embedded on the concrete structure 1 in advance; the combined steel edge rubber waterstop 3 includes a rubber strip 31 and a steel strip 32, and the rubber strip 31 is installed In the steel plate groove 2, the steel plate groove 2 and the rubber strip 31 are arranged along the construction joint between the pre-concrete structure 1 and the post-concrete structure 4; one end of the steel plate strip 32 is embedded in the rubber strip 31, and the other end is placed in the post-concrete structure 4 Inside. In this embodim...

Embodiment 2

[0040] Such as Figure 1-Figure 4 As shown, this embodiment provides the construction method of the waterproof structure using the combined steel edge rubber waterstop in the above embodiment, including the following steps:

[0041] 1) Determine the thickness of the post-concrete structure 4 and the reinforcement requirements for the steel skeleton 41 of the post-concrete structure 4 according to the structural calculation;

[0042] 2) Construct the pre-concrete structure 1, and during the construction of the pre-concrete structure 1, pre-embed the steel plate groove 2 in the pre-concrete structure 1, and at the same time fill the steel plate groove 2 with filler 21 temporarily to prevent concrete from blocking the steel plate groove 2;

[0043] 3) After completing the construction of the pre-concrete structure 1, according to the needs of the post-concrete structure 4, break the enclosure structure or remove the formwork to provide construction space; then according to the wa...

Abstract

The invention belongs to the field of constructional engineering, and particularly relates to a waterproof structure adopting combined steel-edged rubber water stop. The waterproof structure comprisesan early concrete structure, a later concrete structure and the combined steel-edged rubber water stop. A steel plate groove is pre-buried in the early concrete structure. The combined steel-edged rubber water stop comprises a rubber strip and a steel plate strip. The rubber strip is installed in the steel plate groove. The steel plate groove and the rubber strip are arranged along a constructionjoint. One end of the steel plate strip is embedded in the rubber strip, and the other end of the steel plate strip is arranged in the later concrete structure. A construction method of the waterproof structure comprises the steps that the early concrete structure is constructed firstly, and meanwhile the steel plate groove is pre-buried and filled with filler; after the early concrete structureis constructed, the filler is removed; then the rubber strip is plugged into the steel plate groove; and finally, the later concrete structure is constructed, and the steel plate strip is poured intothe later concrete structure. According to the waterproof structure and the construction method thereof, the waterproof performance of a special construction joint of the early concrete structure andthe later concrete structure can be effectively improved.

Description

technical field [0001] The invention belongs to the technical field of construction engineering, and in particular relates to a waterproof structure using a combined steel edge rubber waterstop and a construction method thereof, which is applicable to the design and construction scheme of the waterproof structure of structures such as underground stations and basements in rail transit projects. Background technique [0002] The special construction joints of concrete structures refer to the construction joints formed at the joints between the post-construction structure and the previous structure due to the inability to reserve conventional construction joint waterstops during the early construction of the structure. The conventional waterstop with steel edges on both sides needs to pre-embed one of the steel edges in the preliminary structure, and then pour the other steel edge in the later construction structure, so it cannot be used for this special construction joint. At...
