Abstract
The invention relates to construction work and is intended for replacing buried pipelines. Technical result: increased ease, efficiency and safety of operations. The method includes destroying a pipeline to be replaced (29) and subsequently pulling in a new pipeline (24) by the continuous movement of a chain-type pulling member, first from a working shaft (13) to an auxiliary shaft (25) and then back. The pulling member is assembled from hingedly interconnected links (5), which are provided with a fixed axle (16), to form a chain (3) that bends in only one direction. The chain (3) is assembled on a work table (6), which is installed on the surface of the ground (26) outside the working shaft (13). An apparatus (1) (figure 1) comprises a modular power device (2), and a pulling member in the form of a flexible chain (3). A feed mechanism of the pulling member comprises a work table (6), having an arresting device (8) for the chain (3), and a winch (9), which are mounted on a base (7), or rotating drums (10), mounted on bases (11) and having a cable drive (12), and a lifting mechanism (14) with a protective casing (15), through which the chain is passed (3).
