During trenchless directional drilling construction, chemical mud can be added to the injector, and the addition amount can be adjusted to 0.5- 1 kg per cubic meter.
Rotary excavation construction
During rotary excavation, mud additives should be added according to field equipment. The most primitive and simple method is to directly join the building foundation pit. The advantage is simple and convenient, but the disadvantage is that the number of additions cannot be calculated, resulting in waste and so on.
Geological survey
During drilling construction in geological exploration, chemical mud can be slowly added into the mud mixing irrigation for stirring, and the dosage is 0.3-0.8, which can be adjusted according to the degree of mud lubrication.
