Sectioned grouting pipe and construction method thereof for soft soil stratum reinforcement
The invention provides a sectioned routing pipe and a construction method thereof for soft soil stratum reinforcement. The sectioned routing pipe comprises an outer grouting pipe body, an inner grouting pipe body and grouting-blocking ring plugs, wherein the outer grouting pipe body is a floral pipe, grouting holes are evenly distributed in the surface of a pipe body of the outer pipe body, the inner grouting pipe body is arranged in the outer grouting pipe body, the top end of the inner grouting pipe body is sealed, the bottom end of the inner grouting pipe body is connected with a mortar feeding pipe body, four inner grouting holes are evenly formed in the upper portion of the inner grouting pipe body, the grouting-blocking ring plugs are firmly fixed on the inner grouting pipe body and located on the upper portion and the lower portion of the position where the inner grouting holes are formed, the grouting-blocking ring plugs are closely attached to the inner wall of the outer grouting pipe body, and the grouting-blocking ring plugs and the outer grouting pipe can slide freely along the inner wall of the outer grouting pipe body. According to the sectioned routing pipe and the construction method thereof for the soft soil stratum reinforcement, the accurate soft soil stratum reinforcement can be achieved through the control over the grouting pressure according to the soft soil stratum conditions in a repeating, sectioned and divided mode, and the purposes that the soil stratum reinforcement is achieved quickly and uniformly and the stability is improved are achieved. The sectioned routing pipe and the construction method thereof for the soft soil stratum reinforcement have the advantages that the operation is simple, the cost is low, the economic benefit is high, and the application range is wide.
