Highway railway equipment division machine to get rid of the static rock to break the rock, still get rid of equipment, drilling and hydraulic fracturing pumping heart supporting the use of technology law a working environment: trenchless pipe jacking, tunneling two, trenchless pipe jacking engineering, top tube diameter of about one meter, excavation length of about 200m. Trenchless pipe jacking project, the need to dismantle the hardness of 7.8 degrees silica. Third, the construction conditions prohibit blasting, restricted by the size of the diameter of large construction equipment can not be used hydraulic fracturing machine job or expansive cracking.
