Embodiment

[0024] Embodiment: The high polymer grouting technology and its construction method for tunnel void disease treatment of the present invention include the following contents:

[0025] Based on ground penetrating radar (GPR) or falling weight deflectometer (FWD) to detect tunnel voids; according to the condition of tunnel voids, polymer materials are injected into the voids, and the volume of the materials expands rapidly after the reaction. Cures to quickly fill voids.

[0026] The specific implementation steps are:

[0027] (1) Detection of tunnel void defects based on ground penetrating radar (GPR) or falling weight deflectometer (FWD);

[0028] (2) For figure 1 The tunnel lining that needs to be treated as shown is empty 1, and the grouting holes 2 are drilled at a certain interval, and the hole depth is determined by the thickness of the lining; for figure 2 As shown in the tunnel floor that needs to be treated, the hollow 3 is drilled with grouting holes 4 at a certai...

Abstract

The invention discloses high polymer grouting technology for treating a tunnel void and a construction method thereof. The technology comprises the following steps of: detecting the tunnel void on the basis of a ground penetrating radar (GPR) or a falling weight deflectometer (FWD); and injecting a high polymer material to a void part according to the condition of the tunnel void, wherein after the material reacts, the volume is expanded quickly and the material is cured to quickly fill the void. The technology has the characteristics of good treatment effect, quick construction, no requirement on curing, obvious target, high controllability, cost conservation and the like. Compared with the traditional tunnel void treating method, the technology is innovative obviously in the aspects of technical principle and construction method and develops a new, quick, economical and practical way for maintaining a tunnel and enabling the tunnel to be durable.

Description

technical field [0001] The invention belongs to the tunnel maintenance and repair technology, and relates to the tunnel void disease treatment technology, in particular to the high polymer grouting technology for tunnel lining void and tunnel pavement bottom void disease treatment. Background technique [0002] With the rapid development of my country's transportation industry, the number of tunnels and the scale of construction have reached an all-time high. Since the construction quality and operation management of tunnel engineering involve people's life and property safety, they are highly valued by relevant departments and widely concerned by the society. Tunnel disease is a very important aspect that affects tunnel safety. Therefore, the development of new, efficient, economical, and durable tunnel disease treatment technologies is a key issue that needs to be solved urgently in tunnel construction in my country. [0003] Among tunnel diseases, void is one of the comm...
