Why doesn't the pipe fill the water when drilling?
First use the impact drill, press the location of the drill empty machine, play expansion bolts, in fixed drilling machine, power on, turn on the water pump, and so on, there is water outflow, then slowly push the drilling machine.
Why doesn't the pipe fill the water when drilling? When drilling, the position of the bucket must be higher than the drill bit, so that the water can flow into the drill bit.
Construction sequence of full casing construction method. Its general construction process is: flat site, laying work platform, installation of drilling rigs, pressure casing, drilling hole, placing steel cage, drain pipe, pouring concrete, drawing casing, check the quality of pile.The main construction steps of the whole casing construction method are similar to those of the mud protection method, except for the need of mud and cleaning holes. The verticality of the pressed casing depends on the vertical depth of the 5~6m at the beginning of the excavation. Therefore, the verticality should be checked by level and plumb at any time.
