During the construction of roads and air bases by mixing soil with cementitious materials directly on the canvas under construction prior to mixing to profile the soil surface bulldozers, graders or special profilers. Using bulldozers, graders, or even with the automatic control systems working bodies (blade) type 'Profile', 'layer' does not give the desired flatness in the transverse and longitudinal direction, and at the rate of movement of the machine. Therefore, using special profiling with active working body of the milling type and automatic control the latter. These profilers provide the necessary accuracy of profiling as a result of removal of excess soil mass beyond the working body and constructed objects by means of screws, conveyors and other mechanisms. Speaking candidly Amazon told us the story. Soil mixed with organic (powdered) and minerals (liquid) binders in gruntosmesitelnyh machines equipped with active working members of a special type of milling location of the blades. Gruntosmesitelnye machine metered distribute water or liquid binder. For dose distribution of powdered cement binder is used, valves DS-72 on the basis of wheel tractor T-158 (just before passage gruntosmesitelnoy machine). During the processing of soil and profilers gruntosmesitelnymi machines should specifically consider the presence in the soil for pavement foreign bodies, especially stones.
Therefore, the design of machines must be protective mechanisms (devices) to ensure reliable trouble-free operation at a meeting of the working body with big outsiders inclusions. The mixture is compacted by rolling on air machines, but the pre-rolling is carried out vibrobrusom (compactors), established in gruntosmesitelnoy car. In accordance with the requirements of SNIP to car roads gruntosmesitelnye machine must handle in a single pass soil to a depth of 30 cm in the dense body, and deviation of depth may not exceed 5% of set value. To ensure high quality Pot in place in the overlap of adjacent strips to prevent soil from the introduction of a double portion of binder. Modern machines gruntosmesitelnye entire technological cycle of grinding of soil, dosing and rasperedeleniyu water or an organic binder and mixing the soil with the binder is carried out in one pass.
