Demand for micro pipe jacking

The Need for Micro-Pipe Jacking

In municipal engineering construction, pipe laying is divided into two methods: excavation and trenchless. Since most projects are implemented in built-up areas (such as villages within cities), the width of the laneways is relatively narrow. Continuing with traditional trenching methods would severely damage surrounding buildings and roads, disrupting traffic and failing to meet current construction requirements. Therefore, trenchless pipe laying is necessary. Fiberglass pipe manufacturers often employ pipe jacking and pipe dragging techniques (drag-and-pull construction) in trenchless construction. Drag-and-pull construction is difficult to maintain the designed elevation of drainage pipes, resulting in significant errors, and is generally not recommended for small-diameter drainage pipes. However, slurry jacking (conventional pipe jacking, or medium- and large-diameter pipe jacking) is limited by pipe diameter and generally cannot meet requirements for pipes with diameters less than DN800 (or even less than DN500). To address the problem of excavation and pipe dragging being unsuitable for small-diameter drainage pipes when encountering obstacles such as traffic and buildings, the micro-pipe jacking method is recommended.

The micro-pipe jacking method is well-suited for secondary pipe network construction in densely populated areas, offering rapid construction speed and high precision. Compared with traditional excavation and pipeline laying, this method offers significant environmental and economic advantages, including:

It does not damage existing roads and has minimal impact on traffic;

It produces low noise, produces minimal mud discharge, and has minimal environmental impact;

It ensures civilized and safe construction;

It achieves high precision, employs scientific techniques, and is fast;

It offers low overall construction costs.
