1. under the condition that the geological conditions are distributed unevenly, the double-wheel groove milling machine can incline to a softer stratum, and particularly, when a sandy soil layer is treated, the phenomenon of groove section collapse can occur in the excavation process.

2. When the double-wheel slot milling machine for milling cutter frame body perpendicularity is manufactured, the perpendicularity of the milling cutter frame is monitored according to the perpendicularity requirement of an underground diaphragm wall. And the deviation rectification while drilling is realized by grooving and deviation rectification of the milling cutter frame, and the vertical precision of the underground diaphragm wall is strictly detected and controlled in the construction process.

3. The cutter frame of the guide constraint double-wheel slot milling machine adopts a long guide structure form, for example, the length of a base body of the cutter frame of a creep XTC series double-wheel slot milling machine is 10-15m, the width is 2-3.5m, the thickness is 0.6-2.2m, and the thickness of a formed slot is 0.8-2.5 m. When the initial stage is under construction, when the operation of shallower stratum promptly, the direction of double round slot milling machine equipment because of lacking the deep groove section, the construction initial stage double round slot milling machine tool milling cutter frame can take place violent shake and slope, and the tool milling cutter frame that lacks guide structure can only rely on self to suspend in midair and maintain the balance, and this can lead to construction operation process double round in earlier stage to mill into the groove speed slow, the construction precision is low, if meet local soil body outstanding or collapse can lead to groove section initial stage excavation straightness can not obtain effective control.
