Description
Technical field:
The utility model relates to a kind of measurement mechanism, relates in particular to a kind of device for measuring disturbed soil wind erosion quantity.
Background technology
In Northwest inland arid, semi-arid wind-sand area, primary landforms wind erosion is serious, the construction activities havoc earth's surfaces such as excavation, the heap of all kinds of development construction item such as colliery, railway, highway, power plant, gas transmission line pad, roll, the generation of aggravation wind erosion, development, the accurate measurement how realizing development construction item perturbing area soil drifting amount is a difficult problem always.Measure in production practices at present soil drifting amount the most frequently used be survey pin method, wind erosion bridge method, survey pin method drill rod is inserted development construction item perturbing area Typical area, the height of exposed portion, periodic measurement drill rod ground, represent wind erosion thickness by ground gauge height difference, go out wind erosion quantity according to wind erosion THICKNESS CALCULATION; Wind erosion bridge method is the metal framework utilizing two bridge legs and a crossbeam composition, bridge leg is inserted development construction item perturbing area Typical area, periodic measurement crossbeam, to the change of ground level, represents wind erosion thickness by difference in height, goes out wind erosion quantity according to wind erosion THICKNESS CALCULATION; The subject matter that survey pin method and wind erosion bridge method exist in actual applications is: reading error cannot be avoided, and observation data is not accurate enough.In addition, iron plate method and core cutter method measure wind erosion quantity also has certain application in practice, iron plate method lays stainless steel iron plate at development construction item perturbing area Typical area, iron plate is covered constant weight soil sample, soil erosion amount is calculated by the change of the upper soil sample weight of periodic observation iron plate, the subject matter that iron plate method exists in actual applications is: after shelving a period of time, iron plate cannot embed the soil body, on iron plate, earthing is higher than surrounding ground, and the upper soil sample covered of iron plate is easy to harden, the not easily permeable and intensification of easily absorbing heat of iron plate, change earthing water cut, affect accuracy of observation, core cutter method is that disturbed sample is loaded cutting ring, in periodic measurement cutting ring, soil sample weight change calculates soil erosion amount, the subject matter that core cutter method exists in actual applications is: cutting ring self forms stuffy barrier, has obvious boundary effect, has a strong impact on accuracy of observation.
Utility model content:
The purpose of this utility model is to provide the device for measuring disturbed soil wind erosion quantity that a kind of structure is simple, measuring accuracy is high.
The utility model is implemented by following technical scheme: a kind of device for measuring disturbed soil wind erosion quantity, and it comprises the box-frame that surrounded by vertical steel plate and split slides up and down the Zai Tu mechanism being arranged on described box-frame inside; Described Zai Tu mechanism forms by carrying native framework, year native net and vertical rod; Described box-frame inside be provided with identical with described box-frame shape described in carry native framework, described year native frame end limit and the sliding contact of described box-frame inwall; Be provided with at least three vertical rods at the top avris homogeneous vertical of described year native framework, the top of described vertical rod is placed in described box-frame outside, described vertical rod and the sliding contact of described box-frame inwall; Be provided with described year native net at described year native lower portion, be provided with filter paper at described year soil net top.
Advantage of the present utility model: structure is simple, easy to carry; Box-frame and the split of Zai Tu mechanism are arranged, and year native actuator base is made up of year native net and filter paper, ensure that the soil sample above Zai Tu mechanism is consistent with periphery soil moisture content, effectively reduce error, improve measuring accuracy; When soil sampling, box-frame forms retaining wall, guarantees that sampling accurately; Principle of work is simple, easily operates, directly obtains disturbed soil wind erosion quantity by the weight difference calculating twice soil sample, and metering system is simple, directly can calculate wind erosion quantity.
Accompanying drawing illustrates:
Fig. 1 is one-piece construction schematic diagram of the present utility model.
Fig. 2 is for carrying native whole mechanism structural representation.
Box-frame 1, Zai Tu mechanism 2, year native framework 3, year native net 4, vertical rod 5, filter paper 6.
Embodiment:
As depicted in figs. 1 and 2, a kind of device for measuring disturbed soil wind erosion quantity, it comprises the box-frame 1 that surrounded by vertical steel plate and split slides up and down the Zai Tu mechanism 2 being arranged on box-frame inside; Zai Tu mechanism 2 forms by carrying native framework 3, year native net 4 and vertical rod 5; Be provided with year native framework 3 identical with box-frame 1 shape in box-frame 1 inside, carry native framework 3 end limit and the sliding contact of box-frame 1 inwall; Be provided with four vertical rods 5 at the top avris homogeneous vertical carrying native framework 3, the top of vertical rod 5 is placed in box-frame 1 outside, vertical rod 5 and the sliding contact of box-frame 1 inwall; Be provided with in year native framework 3 inside and carry a native net 4, filter paper 6 is provided with at year native net 4 top, carry native net 4 and filter paper 6 to combine, can ensure that rainwater permeates the ground through filter paper 6 and year native net 4, prevent from testing the loss of soil sample, make the water cut of soil sample above filter paper 6 consistent with the water cut of the periphery soil body, reduce experimental error.
Use step: first, box-frame 1 is inserted ground, box-frame 1 top is above the ground level 1 ~ 2cm, taken out by the soil in box-frame 1, the degree of depth that fetches earth does not exceed box-frame 1, and ensures the Land leveling of box-frame 1 inner bottom part, the soil sample of taking-up is weighed; Then, Zai Tu mechanism 2 is placed in box-frame 1 inside and promotes downwards, until carry native net 4 and the earth surface of box-frame 1 inner bottom part, year native net 4 covers filter paper 6; Again the soil sample after weighing is backfilling into that box-frame 1 is inner, above filter paper 6, backfill soil sample upper surface flushes with periphery soil body earth's surface, upwards takes out box-frame 1 along vertical rod 5; After the regular hour, box-frame 1 is enclosed within vertical rod 5 outside, makes box-frame 1 inwall along vertical rod slide downward, until the ground immediately below the insertion of box-frame 1 bottom, and box-frame 1 top flushes with peripheral ground substantially, take out above filter paper 6, the soil sample of box-frame 1 inside weighs again; Finally, namely the difference calculating twice soil sample weight obtains wind erosion quantity.
