Hard rock bearing platform rope saw cutting device

Abstract

The invention relates to the technical field of rope saws and discloses a hard rock bearing platform rope saw cutting device which is placed on a bearing platform of a hard rock. The hard rock bearing platform rope saw cutting device comprises a fixed frame fixed to the bearing platform of the hard rock, a rope saw cutting structure longitudinally moving along the fixed frame and a driving structure for driving the fixed frame to move longitudinally. The rope saw cutting structure is provided with a saw rope which is arranged in a longitudinal circulating rotation and used for cutting the hard rock, the saw rope is provided with a cutting section which is horizontally arranged and used for cutting the hard rock, and the cutting section is located on the lower portion of the rope saw cutting structure. The hard rock bearing platform rope saw cutting device is fixed to the bearing platform of the hard rock though the fixed frame, so that the position of the rope saw cutting structure is fixed well, the cutting section of the longitudinally arranged saw rope of the rope saw cutting structure is utilized to cut the hard rock, the driving structure drives the rope saw cutting structure to move longitudinally, the cutting depth requirements are met, the rope saw cutting structure is driven to return, the cutting of the whole hard rock does not need exposed explosion or static explosion, the environment is not affected, and the hard rock bearing platform rope saw cutting device is used anytime anywhere, is low in cost, is not subjected to weather influence and is high in construction efficiency.

Description

technical field [0001] The invention relates to the technical field of wire saws, in particular to wire saw cutting equipment for hard rock caps. Background technique [0002] With the increase of the excavation depth of the deep foundation pit of the building basement, it is often encountered that the excavation of the middle pit of the building core tube at the bottom of the deep foundation pit and the foundation cap at the bottom of the foundation pit need to enter hard rock. [0003] In the prior art, the excavation of the hard rock at the bottom of the foundation pit usually adopts open explosion or static explosion technology. Open blasting requires the use of explosives, and vibration, flying stones, noise, dust, etc. have a great impact on the surrounding environment. It is strictly prohibited to use it in the city center, near the subway structure, or near buildings; and the cost of rock excavation using static blasting is high. , and its static explosive agent is ...
