The invention provides a diamond tool bit bevel face grinding device and belongs to the field of an operation technology. The diamond tool bit bevel face grinding device solves the problem that existing diamond tool bit bevel face grinding is conducted through a general-purpose machine tool, and production efficiency is low. The diamond tool bit bevel face grinding device comprises a rack and a clamp used for clamping a diamond tool bit and arranged on the rack. The outer sides, relative to two bevel faces of the clamped diamond tool bit, of the clamp are each provided with a grinding mechanism with a grinding wheel. A feeding mechanism making the corresponding grinding wheel fed in parallel along the corresponding target bevel face is arranged between each grinding mechanism and the rack. By the adoption of the diamond tool bit bevel face grinding device, the bevel faces of the diamond tool bit are fed and ground automatically, the two bevel faces are machined at the same time, and the diamond tool bit bevel face grinding device has the beneficial effect of being high in production efficiency; and the grinding wheels of the diamond tool bit bevel face grinding device can be fed automatically after grinding is shrunk gradually, and the diamond tool bit bevel face grinding device has the beneficial effects of being high in production efficiency and capable of guaranteeing grinding accuracy.

The invention discloses a method for constructing a guide wall in a groove of an underground continuous wall. The digging position of the guide wall is determined according to the axis of the underground continuous wall; , the excavation elevation is controlled by manual trimming; the position of the guide wall is determined on the concrete pad level, and then steel bars are tied, the outer side of the guide wall is replaced by soil formwork, and the inner side is erected with steel formwork; the formwork is removed after the concrete reaches strength, and the inner wall is simultaneously The upper layer supports 80×80mm square timber; add reinforcement bars to make the guide wall a whole and achieve the purpose of impermeability. The construction joints should be staggered from the joints of the underground diaphragm wall; Seams cannot be set on the same section. The construction method has simple and compact steps, the quality of the produced guide wall is stable, meets the design requirements, less material is consumed, the construction period is short, and the production cost is reduced.
