Rear side grouting device for pile
The invention discloses a rear side grouting device for a pile, which comprises a grouting pipe, a grouting head and a spring, the outlet end of the grouting pipe is a truncated cone, the side wall of an inner cavity of the grouting pipe is provided with an annular clamping slot and a baffle ring, the head portion of the grouting head is a cone, the tail portion of the grouting head stretches into the grouting pipe from the outlet of the grouting pipe, the outer side wall of the grouting pipe is provided with a grouting hole and an edge clamping ring, the clamping ring is embedded into the annular clamping slot, one end of the spring abuts against the baffle ring, the other end of the spring abuts against the tail portion of the grouting head, the head portion of the grouting head is sealed, a hollow cavity is formed inside the grouting head, the hollow cavity is communicated with the grouting hole, and penetrates the tail portion of the grouting head; during grouting, a high polymer grouting material enters the cavity of the grouting head via the inner cavity of the grouting pipe under the action of high pressure, and is erupted via the grouting hole to form high-pressure jet flow. The rear side grouting device has stronger operability, wider applicability, more remarkable grouting effect, and higher reliability, does not need be pre-buried in a pile body, and does not generate any damage and influence on the original pile body.
