Rapid grouting and hole sealing device for tunnel lining structure and using method

Abstract

The invention discloses a rapid grouting and hole sealing device for a tunnel lining structure and a using method, relates to the technical field of building construction, solves the problems that an existing grouting guide pipe cannot be recycled and the grouting depth is prone to change in the installation process, does not change the grouting depth and ensures the grouting effect, and adopts the specific scheme that the rapid grouting and hole sealing device comprises the grouting guide pipe; the two ends of the grouting guide pipe are provided with a grouting opening and a grouting inlet respectively, the end, close to the grouting opening, of the grouting guide pipe is sequentially sleeved with the hole sealing mechanism and the outer sleeve steel pipe, and the other end of the grouting guide pipe is provided with a rotary limiting mechanism. The rotary limiting mechanism is composed of a bearing and a spring, the bearing is fixedly arranged at the end, close to the grouting inlet, of the outer sleeve steel pipe in a sleeving mode, one end of the spring is fixedly connected with the outer wall of the bearing, and the other end of the spring is fixedly connected with the outer wall of the grouting inlet end of the grouting guide pipe.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a rapid grouting and sealing device for a tunnel lining structure and a use method thereof. Background technique [0002] The statements herein merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] Grouting refers to the method of injecting some curable grout into the cracks or pores of rock and soil foundation with appropriate methods in construction engineering, and improving its physical and mechanical properties by means of replacement, filling, extrusion, etc. In the existing grouting construction, the grouting process is usually completed by a grouting machine. The grouting machine is a kind of equipment driven by a grouting pump or a grouting piston, which is used to pass the grout through the grouting pipeline. Inject into filled area. [0004] The inventors have found that the currentl...

Problems solved by technology

[0005] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a rapid grouting sealing device for tunnel lining structure and its use method, which can realize the sealing of the gap between the grouting sealing device and the hole wall through the expansion rubber tube, and will The outer space is isolated, and the stretchable rubber hose is used to cover the gap between the grouting conduit and the outer casing steel pipe, preventing the grout from entering the gap between the grouting conduit and the outer casing steel pipe, and using the spring to limit the grouting during the twisting process The movement of the conduit solves the problem that the existing grouting conduit cannot be recycled and the grouting depth is prone to change during installation
