Brief description of the drawings
Below in conjunction with drawings and Examples, the utility model is described in further detail,
Fig. 1 is the structural representation of the soil layer compactness testing arrangement that provides of the utility model;
Wherein 1-soil layer; 2-strain transducer; 3-bearing plate; 4-guide peg; 5-load sensor; 6-hammer; 7-operating handle; 8-strain transducer cable; 9-load sensor cable; 10-data processor.
Detailed description of the invention
As shown in Figure 1, this device comprises bearing plate 3, guide peg 4, hammer 6.Bearing plate 3 is fixed on guide peg 4.Four groups of equally distributed strain transducers 2 are installed, for testing the normal strain of bearing plate 3 on bearing plate 3.Hammer 6, through guide peg 4, is provided with load sensor 5 in hammer 6 bottoms.Guide peg 4 is hollow, and strain transducer 8 cables pass from centre.Two operating handles 7 are arranged at hammer 6 tops.Described strain transducer 2 is connected to data processor by strain transducer cable 8, and described load sensor 5 is connected to data processor by load sensor cable 9.
Described data processor adopts single-chip microcomputer, and is connected with display unit.
The utility model method of operating is as described below: after soil layer 1 has rolled, first determine the position that will detect degree of compaction, then bearing plate 3 is placed on this position.By operating handle 7, hammer 6 is mentioned to certain altitude, then unclamp, hammer 6 is freely fallen along guide peg 4, give bearing plate 3 certain impact force.The load sensor 5 that is fixed on hammer bottom is measured impact load, and the strain transducer 2 that is arranged on bearing plate 3 is measured bearing plate 3 normal strains.Data processor 10, by analyzing bearing plate 3 bears when hammering load and the strain of loaded plate 3, is drawn the modulus of deformation of bottom soil layer 1, and in display unit, shows result, thereby derive the degree of compaction of soil layer 1 by computation model.
