[0030] Example 1:
[0031] A repair method for the lining cavity of highway tunnels with poor surrounding rock, such as figure 1 , figure 2 Shown: includes the following steps:
[0032] a. Use the geological radar to cooperate with the corresponding frequency antenna to detect the cavity or void. The model of the geological radar is TSP203 or TSP203A; to detect the cavity or the uncompacted range and position of the secondary lining 3 of the tunnel and the initial support 1, and cooperate with The geological hammer taps the echo, and marks the contour lines of the cavity or the uncompacted part on the surface of the secondary lining 3 in detail;
[0033] b. Determine the grouting area of the small conduit in the proposed cavity or the uncompacted part, and excavate the secondary lining concrete 4 of 40×40cm.
[0034] c. Excavate 40×40cm secondary lining concrete 4 in the cavity or in the area of uncompact grouting Φ50mm steel flower tube;
[0035] d. First use clean ...
