Fig. 3 is every layer an earth pressure cell arrangement sketch map among Fig. 1.
The specific embodiment
As shown in Figure 1, a specific embodiment of the embankment stake in-situ testing device of the utility model is measured assembly and is formed by being full of 2 the load box of banketing, the native relative settlement measurement mechanism of stake, soil pressure.Banketing 2 is that compaction in layers obtains, and wherein bankets with the part of cushion cap 11 same elevations and is called inter-pile soil 21.
Particularly, in the present embodiment, load box is made up of column 51, scaffold 52, template 53 and some connectors etc., has beneficial effects such as low, the easy acquisition of cost, the big or small facility of adjustment.
The soil pressure force measurement component comprises a plurality of earth pressure cells 6 and plate reading device (not shown in figure 1), and each earth pressure cell 6 is separately positioned on 2 the diverse location of banketing.
The native relative settlement measurement mechanism of stake is arranged on banketing in 2 of load box, mainly comprises first vertical rod 42 and second vertical rod 32.
As shown in Figure 2, particularly, the native relative settlement measurement mechanism of stake comprises first sedimentation mark that is arranged on the cushion cap 11 and is arranged on second sedimentation mark on the inter-pile soil 21.
First sedimentation mark comprises that the upper end that is set with first vertical rod, 42, the first vertical rods 42 on first substrate, 41, the first substrates 41 is provided with first cantilever 43 of horizontal arrangement.First substrate 41 is a square plate, is processed by the iron plate of length of side 400mm.
First vertical rod 42 is connected and composed through bolt by plurality of sections of steel pipes, optionally the free adjustment height.
Second sedimentation mark is identical with first sedimentation mark structure, comprises that the upper end that is set with second vertical rod, 32, the second vertical rods 32 on second substrate, 31, the second substrates 31 is provided with second cantilever 33 of horizontal arrangement.
Second sedimentation mark is provided with first sedimentation mark in opposite directions, and especially, second cantilever 33 and first cantilever, 43 keeping parallelisms are good.
