Embodiment 1
[0020] The main structure of the active drainage anti-floating segment involved in this embodiment includes the segment body 100, the drain pipe 101, the drain hole 102, the grouting hole 103, the corner block 104, the water stop strip 105, the anti-collision strip 106, the arc Shaped side end face 107, rectangular side end face 108; The arc length direction of the arc-shaped outer surface of the arc-shaped sheet-shaped segment body 100 is provided with a semicircular groove, and a drain pipe 101 is embedded in the groove, and the drain pipe 101 top is provided with Dense tiny holes, so that the excess water precipitated after grout hardening can be discharged, provide grout filling and hardening space for secondary grouting, and improve the filling rate and compactness of grout; the two ends of the drain pipe 101 are provided with drain holes 102, The grouting water is discharged from the drain hole 102; the highest part of the arc-shaped outer surface of the segment body 100 ...
Embodiment 2
[0023] Such as figure 1 and figure 2 As shown, the active drainage anti-floating segment includes a segment body 100, and the segment body includes a drain pipe 101 located outside the arc-shaped outer surface. Among them, the segment body 100 is an arc-shaped sheet with a certain thickness, and the drain pipe 101 is used to discharge the excess water precipitated after the grouting grout is hardened, so as to provide a grout filling and hardening space for the secondary grouting, so as to improve The filling rate and compactness of the slurry.
[0024] Specifically, another example figure 1 and figure 2 As shown, the drain pipe 101 is arranged along the arc length direction of the arc-shaped outer surface of the segment body 100, the drain pipe 101 is a semicircular structure, the arc-shaped outer surface of the segment body 100 is provided with a semicircular groove, and the drain pipe 101 is embedded in the groove of the arc-shaped outer surface, and cast together wit...
