Construction method of cutting underground obstacle with wire saw

Abstract

The invention discloses a construction method of cutting an underground obstacle with a wire saw. The construction method comprises the following steps of a, determining a cutting point by referring to the position relationship between the underground obstacle and the construction interval according to a drawing; b, drilling on the two sides of the cutting point of the obstacle symmetrically with a drilling rig to form two drilling holes, and placing a circular tube into each drilling hole to protect the wall, wherein each circular tube is provided with a notch extending in the length direction, and the notches in the two circular tubes are arranged in opposite; c, assembling the wire saw; d, putting down a support component slowly, and starting a drive device until the obstacle is cut off. In the way, the construction method has the advantages of being safe and reliable, economical and reasonable and convenient in construction, the time limit for a project can be effectively reduced, and the impact exerted on the surrounding environment is small, so the construction method is resource-saving and environment-friendly.

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 cutting underground obstacles with a wire saw machine. 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, but this method requires a large construction space, long construction period, and high cost; Chinese ...

Problems solved by technology

[0003] The common treatment method is to carry out large excavation and remove them one by one, but this method requires a large construction space, a long construction period, and high cost; Chinese patent application 201410159429.5 discloses a construction method for removing underground obstacles, which does not require large excavations. But its disadvantage is that it is necessary to use a slotting machine to slot first, and then use a cutting machine to cut off underground obstacles, and the construction volume is still relatively large.
