Abstract

The invention discloses a clearing construction method for an underground obstacle. The method comprises the following steps of a, looking up the position relation between an underground obstacle anchoring section and a construction interval according to a blueprint; b, grooving to the obstacle position at the upper part of the underground obstacle anchoring section by a grooving machine, grooving at least two grooves and forming at least two groove areas; c, cutting off the underground obstacle in part of the groove areas by a cutting machine, and separating the part, positioned in the construction interval, of the underground obstacle from the underground obstacle body; d, pulling the underground obstacle from the other groove areas by a mechanical device; e, backfilling the groove areas. By the mode, the clearing construction method has the advantages of safety, reliability, economy, reasonability and convenience in construction, the duration can be effectively saved, the influence to peripheral environment is small, and the clearing construction method belongs to a resource-saving and environment-friendly construction method.

Description

technical field [0001] The invention relates to all construction engineering fields such as construction, municipal administration, transportation, water conservancy, electric power, industry, etc., and in particular relates to a construction method for removing underground obstacles. Background technique [0002] In recent years, with the rapid development of economic construction, underground engineering projects such as urban subway tunnels and underground space development have entered a stage of rapid development. During the construction process, anchor cables, anchor rods, soil The problem that obstacles such as nails need to be removed, and dealing with these underground obstacles has become a thorny problem in underground engineering construction. [0003] The common treatment method is to carry out large excavation and remove them one by one. However, this method requires a large construction space, a long construction period, and high cost, and cannot fully meet th...
