Example Embodiment

[0032] The present invention will be further described below with reference to the drawings and embodiments.

[0033] See figure 1 , The elastic grouting back pressure sealing structure of this expansion joint includes deformation joints located between two concrete interfaces in urban underground pipe corridors, high-speed rail tunnels, ordinary railway tunnels, highway tunnels and other structures and containing groundwater 2 or containing groundwater 2 in the rainy season 1. The deformation joint 1 is provided with a grouting material layer 4, an elastic material layer 5, an elastic tube 6, and an epoxy cement stagger 7 for sealing groundwater 2 in sequence.

[0034] Further, the concrete surface is provided with a grouting hole 3 connected to the inside of the deformation joint 1, and an aluminum pipe is embedded in the grouting hole 3. After the grouting material layer 4 is grouted by the aluminum pipe, the entrance of the aluminum pipe is sealed The plug is provided with epox...

Abstract

The invention discloses an elastic grouting counter-pressure sealing structure of an expansion joint. The elastic grouting counter-pressure sealing structure of the expansion joint comprises a deforming joint which contains underground water or has underground water during a rainy season and is located between two concrete interfaces in structures such as an urban underground pipe galley, a high-speed railway tunnel, a normal railway tunnel and a highway tunnel; and a grouting material layer, an elastic material layer, an elastic pipe and an epoxy grout staggered platform are sequentially arranged in the deforming joint from inside to outside and are used for blocking underground water. The invention further discloses a constructing method for the elastic grouting counter-pressure sealing structure of the expansion joint. According to the elastic grouting counter-pressure sealing structure of the expansion joint, sealing for the deforming joint can be conducted effectively, and the problems of repeated seepage and falling of sealing materials in the prior sealing art are solved.

Description

technical field [0001] The invention relates to the field of water leakage control at expansion joints, settlement joints, deformation joints and other parts reserved in high-speed railways and urban rail transit tunnels, and specifically refers to an elastic grouting backpressure sealing structure for expansion joints and a construction method thereof. Background technique [0002] According to the national medium and long-term railway network plan and urban rail transit development plan, China's high-speed railway and urban rail transit have entered a period of blowout development. With the rapid development of high-speed railway and urban rail transit, the corresponding construction and maintenance technologies have also developed rapidly. progress, but also encountered a series of technical difficulties and challenges. Especially in the plateau and hilly areas, the continuous mountains are like obstacles on the way for China's high-speed rail technology to take off and g...
