Abstract
The utility model is related to a kind of river bottom mud measurer for thickness, including an outside loop bar and an inner side stock, the outside loop bar upper end is operation handle, lower end is disk, from top to bottom mark lengths, and 0 graduation mark aligns with operation handle lower end, the disk is fixed as one with outside loop bar, the inner side stock upper end sets operation handle, and lower end is centrum, and the length below the operation handle of the outside loop bar is equal to the overall length of inner side stock.Because pressure suffered by body surface and contact area are inversely proportional, when the disk that outside loop bar lower end is fixed is acted on bed mud with centrum tip, the pressure that bed mud is subject to has very big difference, the utility model determines the page of water body and bed mud using this principle by the disk of outside loop bar lower end, the distance of card is stretched out according to inner side stock lower end, the thickness of river bottom mud can be accurately drawn, its numerical value can directly be read by along the scale marker with outside loop bar intersection location in the stock operation handle of inner side.
Description
Technical field
The utility model is related to river water body bed mud measurer for thickness, is measured available for bed mud mud in training of channel engineering
The collection of amount and riverbed structure basic data.
Background technology
In river bottom mud dredging work, it is necessary first to river bottom mud mud amount is adjusted, the big of bed mud thickness is surveyed
The small accounting result for determining mud amount, the accuracy of measured result is directly connected to duration control and cost control in project management
System.
Need to be measured the structure in river course in sample area during the basic data acquisition in river course, wherein important
An index be exactly bed mud thickness.
At present, the straightforward procedure of measurement river bottom mud thickness is exactly to be inserted into river with a simple stock in actual applications
Bottom, observes the residual bed mud vestige of stock, thus judges riverbed bed mud thickness after extraction.This method measurement error is very big,
And extract during stock, water body easily washes away the residual bed mud on bar, it is impossible to judge bed mud actual thickness, obtain compared with
The measurement result of big error.
Utility model content
The purpose of this utility model is to provide a kind of river bottom mud measurer for thickness, to solve in bed mud thickness measure
The big technical problem of error.
In order to solve the above problems, the utility model provides a kind of river bottom mud measurer for thickness, including an outside
Loop bar and an inner side stock, the outside loop bar upper end is operation handle, and lower end is disk, from top to bottom mark lengths, 0 quarter
Degree line aligns with operation handle lower end, and the disk has larger surface area and is fixed as one with outside loop bar, described interior
Side stock upper end sets operation handle, and lower end is centrum, and the following length of operation handle of the outside loop bar is equal to inner side stock
Length.
The technical solution of the utility model is:Because body surface pressure and contact area are inversely proportional, outside loop bar lower end
When fixed disk is acted on bed mud with centrum tip, because the pressure that the different bed muds of both contacts area are subject to has very big difference
It is different.Using this principle, the pressure that the disk of outside loop bar lower end is subject on bed mud is small, and only the bed mud acted on is produced
Micro deformation, therefore can be with exact residence at the interface of water body and bed mud;And inner side stock lower end be vertebral body structure, bed mud by
The pressure arrived is huge, and inner side stock is inserted into the bottom of bed mud in the presence of own wt and external force, then long according to inner side
The distance of card is stretched out in bar lower end, can accurately draw the thickness of river bottom mud.
Further, inner side stock stretch out card length, its numerical value can by the stock operation handle of inner side along with it is outer
The scale marker of side loop bar intersection location is directly read.
The beneficial effects of the utility model are:
Measurement apparatus can directly read measurement result, facilitate data processing and record;
Measuring appliance does not need electricity consumption, safe operation;
Measurement apparatus is simple in construction, easy to operate.
Brief description of the drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the partial schematic diagram of scale marker 4 in Fig. 1.
Embodiment
River bottom mud measurer for thickness as shown in Figure 1, including outside loop bar 2, bar top attended operation handle
1, connection area larger disk 6 in lower end is mutually perpendicular and is fixed as one;The hollow fluting of outside loop bar 2, is nested inside with
Inner side stock 3, the upper end of inner side stock 3 was connected with operation handle 5, operation handle 5 along 0 quarter marked with outside loop bar 2
Spend line to overlap, the lower end of inner side stock 3 is vertebral body structure.
During operation, hand-held handle 1 and operation handle 5 are steadily put into river course to be measured, when disk 6 is by bed mud resistance
During effect, operation handle 1 is unclamped, inner side stock 3 is allowed in own wt and the work of application external force by continuing pressing operation handle 5
With lower insertion bed mud, until by resistance it is larger when stop exerting a force, now inner side stock 3 is inserted into the length as institute in bed mud
Survey the thickness of river bottom mud.Further, inner side stock 3 is inserted into the length in bed mud and can compareed by edge in operation handle 5
The scale marker 4 set on outside loop bar 2 is directly read, and both numerical value are equal.
Principle of the present utility model and embodiment are set forth above by specific implementation example, are preferably real
Mode is applied, not to limit the utility model.
Claims (4)
1. on a kind of river bottom mud measurer for thickness, including an outside loop bar and an inner side stock, the outside loop bar
