Abstract

The invention relates to the technical field of building construction, in particular to a grooving construction method. The grooving construction method comprises the following steps: determining a grooving position; constructing a guide wall to form a guide wall groove; placing a rectangular drill bit at the bottom of the guide wall groove; crushing a rock stratum by utilizing plasmas generated by the rectangular drill bit to form a groove section; cleaning the bottom and the side wall of the groove section; and hoisting a reinforcement cage, and pouring concrete. According to the grooving construction method, the plasmas are generated through the rectangular drill bit, a plasma channel is formed, the pressure in the plasma channel is rapidly increased under the action of high temperature along with the high temperature and high pressure while the plasma channel is formed, so that the plasma channel is expanded and breaks down rocks, and the surrounding rocks are crushed; and the plasmas are adopted to crush various rock stratums, so that the rock crushing effect is good, construction equipment does not need to be replaced, the construction efficiency is high, and the construction cost is reduced.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a groove-forming construction method. Background technique [0002] At present, in the field of piling diaphragm wall, the common construction equipment is double-wheel milling, grab bucket, rotary drilling rig, three-axis mixer, excavator, etc. The diameter of the groove is generally between 0.8 and 1.5m. In the way of trough formation, different equipment is used for construction according to different depths and trough diameters of different strata. According to the influence of different hardness rock formations and engineering, use different mechanical equipment or replace different drill bits. For example, for near-surface soil layers, hydraulic grab equipment is usually used to construct grooves; when entering strongly weathered rock layers or slightly weathered rock layers with low strength After that, it needs to be replaced with double-wheel milling equip...
