TRENCH FORMING CONSTRUCTION METHOD
Document Type and Number:
WIPO Patent Application WO/2022/227725
Kind Code:
A1
Abstract:
A trench forming construction method, comprising the following steps: determining a trench forming position; constructing a guide wall so as to form a guide wall trench; placing a rectangular drill bit into the bottom of the wall guide trench; using plasma generated by the rectangular drill bit to crush a rock stratum, so as to form a trench section; cleaning the bottom and side walls of the trench section; and hoisting a reinforcement cage and pouring concrete. The construction method generates plasma by means of the rectangular drill bit and forms a plasma channel, the formation of the plasma channel is accompanied by high temperature and high pressure, and the pressure in the plasma channel sharply increases under the action of the high temperature, such that the plasma channel expands and breaks through rock, and the surrounding rock is thus crushed. Plasma is used for crushing various rock stratums, such that the rock breaking effect is good, no construction apparatus needs to be replaced, the construction efficiency is high, and the construction cost is reduced.
