Abstract
The utility model provides a kind of determinator of soil permeability, comprises cylindrical shell, and the lower end of cylindrical shell is cutting ring shape otch, and the inside and outside both sides of cylindrical shell are vertically respectively arranged with scale label.Comparatively complicated with the infiltration cartridge solving existing mensuration soil permeability, parts are more, operate comparatively inconvenience and the problem higher to the requirement of placing place, it is very inconvenient especially to use at Special section as environment of karst.The utility model is used for soil property sensing equipment field.
Description
Technical field
The utility model relates to a kind of measurement mechanism, belongs to soil property determinator field.
Background technology
Carrying out, in method for measuring, mainly using core cutter method to soil permeability at present, is secondly infiltration cylinder method.For core cutter method, soil sample needs through multiple working procedure, and soil texture is easily damaged, very large to the change of soil physical properties, and operation comparatively bothers, and the accuracy of data is relatively low.It two is infiltration cylinder methods, the infiltration cartridge occurred at present is comparatively complicated, parts are many, inconvenient operation, higher to the requirement of placing place, the area bad at topographic condition not easily completes mensuration work, and under the environment that especially image-stone mountain, karst are such, existing method is very inconvenient.
Summary of the invention
The purpose of this utility model is: the determinator providing a kind of soil permeability, comparatively complicated with the infiltration cartridge solving existing mensuration soil permeability, parts are more, operate comparatively inconvenience and the problem higher to the requirement of placing place, especially in Special section use as environment of karst.
Scheme of the present utility model is as follows: a kind of determinator of soil permeability, comprises cylindrical shell, and the lower end of cylindrical shell is cutting ring shape otch, and the inside and outside both sides of cylindrical shell are vertically respectively arranged with scale label.
The scale label being arranged on cylindrical shell inner side and outer side is respectively interior scale and EXT scale, interior scale with the upper end of cylindrical shell for starting point, EXT scale with the lower end of cylindrical shell for starting point.
The upper end of cylindrical shell is fixedly installed the cylinder eaves of loop configuration, and the upper surface of cylinder eaves is planar structure.
The lower end of cylindrical shell is arranged with protective sleeve.
Compared with prior art, major advantage is that assay device structures described in the utility model is very simple to the utility model, and convenient making, saves material; Use more convenient, connect closely between device each several part, the more existing determinator structure of this device very simplifies, floor area is less, be not vulnerable to the restriction of topographic condition, such as under karst topography, be difficult to find large-area soil or silt ground, generally can only find very little face, soil, existing determinator is due to complex structure, and general volume cannot measure more greatly, and this device due to structure and principle simple, can be made into the device that volume is very little, be convenient to measure this particular surroundings, measure effect comparatively stable; Simple to operate, there is no complex control, easy to carry; Reduce the impact of external condition, there is no too much corner, hole, space between this device combiner, not easily clogged by soil in the wild, decrease the impact on mensuration process and precision.

Fig. 1 is structural representation of the present utility model;
Fig. 2 is the sectional structure schematic diagram of Fig. 1;
Fig. 3 is the structural representation after Fig. 1 middle cylinder body lower end puts protective sleeve.
Embodiment
For making the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with Fig. 1, Fig. 2 and Fig. 3, the utility model is described in further detail,
Embodiment 1:
The utility model embodiment provides a kind of determinator of soil permeability, comprising:
Cylindrical shell 1, the edge structure of annular that to be the lower end of cutting ring shape otch 11(and cylindrical shell 1 be the lower end of cylindrical shell 1), be convenient to break ground during the press-in soil of cylindrical shell 1 lower end, reduce resistance, and the inside and outside both sides of cylindrical shell 1 be vertically respectively arranged with scale label.
Preferably, the scale label being arranged on cylindrical shell 1 inner side and outer side is respectively interior scale 3 and EXT scale 4, interior scale 3 with the upper end of cylindrical shell 1 for starting point, EXT scale 4 with the lower end of cylindrical shell 1 for starting point.
Cylindrical shell 1 is preferably columnar structured, and the upper end of cylindrical shell 1 is fixedly installed the cylinder eaves 2 of loop configuration, and the upper surface of cylinder eaves 2 is planar structure, and the internal diameter size that the diameter dimension of cylinder 1 is greater than an eaves 2 is less than the outside dimension of an eaves 2.Cylinder eaves 2 is mainly used in the area increasing cylindrical shell 1 upper end; when cylindrical shell 1 is pressed in soil; more large-arealy can knock by one's hands or hammer etc. the power that instrument transmits; protect cylindrical shell 1 not knock instrument direct effect with hammer etc. simultaneously; prevent cylindrical shell 1 from deforming, affect cylindrical shell 1 volume, ensure estimating precision.
Preferably, the lower end of cylindrical shell 1 is arranged with protective sleeve 5, entangles the cutting ring shape otch of cylindrical shell 1 lower end, when not using, prevents from scratching people or other objects.
In practical measurement operation, first select the place needing to carry out measuring, in soil, select suitable soil face, determine the different mensuration degree of depth.After having determined place, cylinder 1 is pressed in soil, during press-in with cutting ring otch one end towards soil, compression distance is (compression distance is measured by EXT scale 4) between 2-3cm, keeps cylinder 1 vertical in process of press in.After completing cylinder 1 process of press in, measure the clear water of appropriate amount with graduated cylinder, prepare writing time simultaneously, after being ready to complete, when writing time, the water measured is added in cylinder 1 simultaneously.After the water was added, the change of moment observing water quantity, the water yield is all penetrated in writing time in moment of moment in soil or regulation and cylinder (if water does not penetrate in soil completely at water, then measure water level decreasing height in cylinder 1 by interior scale 3, thus calculate the water yield penetrated in soil), after having recorded, take out cylinder 1.Afterwards, excavate soil in identical place, check the length of penetration (can with tape measure etc. measure) of water in underground, and record in addition.Above step is repeated more than 3 times.Finally by the water yield of permeating, time and the length of penetration of water in underground, multiplicity, calculate the permeability of soil.
