Abstract

The invention discloses a multipurpose tool pipe for manual pipe jacking. The multipurpose tool pipe comprises a tool pipe body, a sliding supporting assembly, a plugging assembly and a blade foot. The sliding supporting assembly is arranged at the top of the inner side of the tool pipe body, the sliding supporting assembly comprises an arc-shaped sliding plate with the horizontally-arranged L-shaped cross section, the sliding supporting assembly comprises a horizontally-arranged arc-shaped sliding plate and a vertical base plate at the left end, a plurality of horizontal threaded circular grooves are formed in the vertical base plate, and supporting circular rod sets arranged in the length direction of the arc-shaped sliding plate are arranged in the horizontal threaded circular grooves. The plugging assembly comprises a circular sealing plate, and the sealing plate is divided into an upper plate and a lower plate. According to the multipurpose tool pipe for manual pipe jacking, the safety risk of operation outside the pipe can be greatly reduced, a subsequent operation space is provided, more complex underground conditions can be dealt with, temporary plugging is effective, rapid and convenient, and additional measures of pipe jacking construction are reduced; and the construction progress can be effectively accelerated, the construction efficiency is improved, the construction period is shortened, and the management and construction cost is saved.

Description

technical field [0001] The invention relates to the field of trenchless construction of underground pipelines, in particular to a multipurpose tool pipe for artificial pipe jacking. Background technique [0002] Pipe jacking construction is an underground pipeline construction method developed after shield tunneling construction. It does not need to excavate the surface layer, and can cross roads, railways, rivers, ground buildings, underground structures and various underground pipelines. The pipe jacking construction relies on the thrust of the main jacking cylinder and the relay room between the pipelines to push the tool pipe or roadheader from the working well through the soil layer to the receiving well for hoisting. At the same time, the pipeline following the tool pipe or the boring machine is buried between the two wells, in order to realize the construction method of laying the underground pipeline without excavation. [0003] After years of development, pipe jack...
