Abstract
The utility model discloses an excavated-rock-soil-volume measuring device in the rock soil measuring engineering investigation, which comprises a hollow ring-shaped body; a movable piston is arranged in the ring-shaped body and connected with a piston rod; an upper cover is arranged at one end of the ring-shaped body; a piston rod through hole is formed in the center of the upper cover; and the piston rod is movably arranged in the piston rod through hole; an elastic membrane is connected at the other end of the ring-shaped body in a sealing manner; and a base is arranged outside the elastic membrane. The moving distance of the piston can be accurately and conveniently measured; one end of the rock-soil-volume measuring device provided with the elastic membrane is placed on the transverse plane of holes of a measured soil body, so that when the piston is downwards pushed, the elastic membrane extends, and the space of the measured hole (pit) is filled with liquid in a manner that the liquid and the inner wall of the hole (pit) is separated through the elastic membrane; and according to the moving distance of the piston and the section surface of the ring-shaped device, the value of the volume of the measured body can be conveniently and accurately obtained, and the volume of the rock soil extracted from the measured hole can be obtained. In addition, the utility model has the advantages of convenient and simple operation and accurate measurement.
Description
Technical field
This utility model relates to a kind of measuring apparatus of irregular size, particularly measures in the geotechnical engineering investigation measuring appliance to the ground volume that digs out.
Background technology
In geotechnical engineering investigation work, the unit unit weight of measuring soil is used the degree of tightness of the structure of understanding soil, the inspection and the control of compaction all be unable to do without native this index of unit unit weight during for the calculating of shelves cob wall soil pressure, artificial and design that natural slope is stable and accounting, foundation bearing capacity and settling amount and subgrade and pavement construction.Parameters needed is exactly the volume and weight of the tested soil body when measuring this index.The method of measuring soil body weight is comparatively simple and convenient, then acquires a certain degree of difficulty for the mensuration of soil body volume.Core cutter method is arranged at present, the method for sealing with wax, whiteruss method and radioisotope method etc., but all be that complexity and error are bigger, all the more so especially at the construction field (site).
Summary of the invention
The purpose of this utility model is in order to overcome the deficiencies in the prior art, for solving the problem that the intrinsic volume of soil body atypical characteristic is difficult to measure, provides a kind of easy to operate simple and easy, accurate ground device for volume measurement of measurement.
The purpose of this utility model is achieved in that a kind of ground device for volume measurement, comprises a hollow ring body, it is characterized in that being provided with moveable piston in the described annular solid, and piston is connected with piston rod; Annular solid one end is provided with loam cake, and the loam cake center is provided with the piston rod through hole, and piston rod is movably arranged in this piston rod through hole; The annular solid other end flexible sheet that is tightly connected, and base is arranged in the arranged outside of flexible sheet.
Further, described annular solid is transparent annular solid, and annular solid is provided with reading.
Further, piston rod is provided with reading.
Owing to adopted technique scheme, between transparent annular solid internal dielectric membrane sheet and piston, formed a confined space, inject liquid in this airtight space.Promote piston rod, can read the distance that piston moves by reading on the transparent annular solid or the reading on the piston rod.
An end that this ground device for volume measurement is provided with flexible sheet is placed on the transverse plane in tested soil body hole, promotes piston downwards, and flexible sheet then extends, and liquid then will take the space in tested hole (hole) across flexible sheet.The distance that moves according to piston and the sectional area of circulator, can learn used liquid volume, after the fixing dead volume of this apparatus of deduction, can make things convenient for the bulking value that obtains measured body exactly, thereby learn the volume of the ground that takes out in this tested hole.The utility model easy to operate simple and easy, measure accurately.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing and embodiment.
Accompanying drawing is a structural drawing of the present utility model.
Among the figure: 1, piston rod, 2, loam cake, 3, piston, 4, annular solid, 5, flexible sheet, 6, base.
Embodiment
Embodiment 1:
As shown in drawings among the embodiment, the ground device for volume measurement comprises a clear hollow annular solid 4, annular solid 4 is provided with reading, one flexible sheet 5 is housed in the bottom of annular solid, be connected with base 6 at flexible sheet 5, be provided with loam cake 2 in the upper end of annular solid, loam cake 2 centers are provided with the piston rod through hole; Be provided with a piston mobile 3 in annular solid, be connected with piston rod 1 on the piston 3, piston rod 1 is arranged in the piston rod through hole at loam cake 2 centers.Form a confined space at piston 3 and 5 of flexible sheets, the distance that piston moves can accurately be measured easily.Fill with common liq in this airtight space after, place it on the transverse plane in tested soil body hole (hole), promote piston downwards, liquid then will take the space in tested hole (hole).The distance that moves according to piston and the interior sectional area of annular solid can make things convenient for the bulking value that obtains measured body exactly.
Embodiment 2:
The ground device for volume measurement comprises a hollow ring body 4, and reading is not set on the annular solid 4, and piston rod is provided with reading, and other structures are identical with embodiment 1.
