Embodiment 1

[0052] see Figure 1-Figure 3 , the present embodiment proposes a bridge support waterproof device, including an upper plate 1, a sealing ring 2, a waterproof cover 3, an elastic displacement device 4 and a lower plate 5, wherein: the upper plate 1 is pre-embedded in the beam body, the The upper plate 1 is connected to the upper part of the waterproof cover 3, and several sealing rings 2 are arranged between the waterproof cover 3 and the upper plate 1; the lower part of the waterproof cover 3 is connected to the elastic displacement device 4; The elastic displacement device 4 is connected with the lower plate 5 , and the lower plate 5 is pre-embedded on the side of the abutment 7 . The upper plate 1 is sealed and connected to the upper part of the waterproof cover 3, and the elastic displacement device 4 is non-sealed connected with the waterproof cover 3 and the lower plate 5, so that the beam body and the upper plate 1. A semi-enclosed space is formed between the waterproo...

Embodiment 2

[0058] The difference between this embodiment and embodiment 1 is:

[0059] see Figure 5 The sealing structure of the upper part of the waterproof device is as follows: the upper surface of the waterproof cover 3 is provided with the concave ring groove, and the sealing ring 2 is placed in the concave ring groove, so as to realize the complete waterproofing of the upper part of the waterproof device.

Embodiment 3

[0061] The difference between this embodiment and embodiment 1 is:

[0062] see Figure 6 , the sealing structure of the upper part of the waterproof device is as follows: the lower surface of the upper plate 1 and the upper surface of the waterproof cover 3 are provided with the concave ring groove, and the sealing ring 2 is placed in the concave ring groove. In order to realize that the upper part of the waterproof device is completely waterproof.

Abstract

The invention relates to the technical field of bridge support waterproofing, aims to solve the problem that the service life of a bridge support is affected due to the fact that the bridge support is soaked in water for a long time, corrosion of the support is aggravated, a sliding pair of the support is damaged, and provides a bridge support waterproofing device which comprises an upper plate, a waterproof cover, an elastic displacement device and a lower plate. The upper plate is in sealed connection with the upper portion of the waterproof cover, the lower portion of the waterproof cover is connected with the elastic displacement device, the elastic displacement device is connected with the lower plate, the lower plate is embedded in the side face of an abutment, the elastic displacement device is in non-sealed connection with the waterproof cover and the lower plate, and the beam body, the upper plate, the waterproof cover, the lower plate and the abutment jointly form a semi-closed space. Air pressure in the waterproof device is used for resisting water level rise, so that water level difference is formed inside and outside the waterproof device, the support cannot be eroded by water, the support is protected, the corrosion resistance of the support is effectively improved, and the service life of the support is prolonged.

Description

technical field [0001] The invention relates to the technical field of bridge support waterproofing, in particular to a bridge support waterproof device. Background technique [0002] As an important component of the bridge system, the bearing is located between the abutment and the beam body, and mainly bears the load of the upper structure of the bridge system and adapts to its rotation and displacement. With the development of diversification and complexity of bridge construction, nowadays, due to the influence of the surrounding environment and terrain, the location of bridge piers is relatively low when selecting sites for many bridges, resulting in long-term immersion of bearings in water during service , which will greatly aggravate the corrosion of the bearing and damage the sliding pair of the bearing, thereby affecting its service life. Contents of the invention [0003] The invention aims to provide a bridge support waterproof device to solve the problem that t...
