Abstract
The utility model discloses a pressure test device for a soil body. The pressure test device comprises an elastic bag body and a pipeline, wherein the pipeline comprises a transverse pipe and a vertical pipe, one end of the transverse pipe is communicated with the elastic bag body; the other end of the transverse pipe is communicated with the vertical pipe; and scale lines for measuring the height of an object in the vertical pipe are formed on the vertical pipe. According to the pressure test device for the soil body, the problems of relatively high cost and complicated test of the conventional vibration wire type soil pressure box are solved; the pressure test device has a simple structure, is easy to operate and low in cost and cannot be limited by a working environment; and a novel way is supplied to soil pressure test.
Description
Technical field
The utility model is a kind of pressure test device, specifically is meant a kind of device that is used for the testing engineering soil pressure.
Background technology
Develop rapidly along with China's economic construction; A large amount of infrastructure are constantly built; In construction process, for the design theory and the monitoring works safety of construction of checking engineering, carrying out the soil pressure test is an important job; As in engineerings such as cement mixing pile composite foundation and pattern foundation pit supporting structure, the test soil body and pile body pressure are most important.At present, the most frequently used instrument of soil pressure test is the type vibration wire earth pressure cell, and this device is a cover internal construction complicated electronic device, working environment is had relatively high expectations, and complicated operation, involve great expense.
The utility model content
The purpose of the utility model has been to provide a kind of easy and simple to handle, low soil pressure testing arrangement that does not receive the working environment restriction of expense.
For realizing above-mentioned purpose; The technical scheme of the utility model is such: a kind of soil pressure testing arrangement; Comprise elastic sack body and pipeline, above-mentioned pipeline comprises transverse tube and vertical tube, and an end and the above-mentioned elastic sack body of above-mentioned transverse tube are connected; The other end of above-mentioned transverse tube and above-mentioned vertical tube are connected, and above-mentioned vertical tube is provided with the graduation mark of the height that can measure the material in the above-mentioned vertical tube.
Above-mentioned elastic sack body is a rubbery human body, and above-mentioned rubbery human body is ellipsoid.
Above-mentioned transverse tube and above-mentioned vertical tube are lucite tube, and the caliber of the caliber of above-mentioned transverse tube and above-mentioned vertical tube is 1-3cm.
Offer the confession outer water on the above-mentioned elastic sack body and inject the water inlet in the above-mentioned elastic sack body, be covered with dismountable seal cover on the above-mentioned water inlet.
After adopting such scheme, a kind of soil pressure testing arrangement of the utility model is during test; Fill out on elastic sack body earlier the elastic sack body fills with water, and then with the soil body, along with the increase of the depth of fill; The pressure that receives on the elastic sack body is increasing, and at this moment, the water in the elastic sack body can be squeezed out to the transverse tube of pipeline by the soil body; And in transverse tube flows into vertical tube, when the depth of fill reaches the depth of fill to be tested, stop to banket; Suffered soil pressure equals the pressure of water generates in the vertical tube on this moment elastic sack body; According to the calculation of pressure formula, can converse the pressure of water generates through the height of water level that reads water in the vertical tube, and then draw soil pressure suffered on the elastic sack body.The soil pressure testing arrangement of the utility model; Avoided that type vibration wire earth pressure cell expense is higher, the problem of testing complex; Have simple in structure, easy and simple to handle, expense is low, does not receive the effect of working environment restriction, for the soil pressure test provides a kind of new approach.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure:
Rubbery human body 1 pipeline 2
Transverse tube 21 vertical tubes 22
Graduation mark 3
The specific embodiment
A kind of soil pressure testing arrangement of the utility model, as shown in Figure 1, comprise rubbery human body 1 and pipeline 2; Wherein,
Rubbery human body 1 is ellipsoid; Offer a water inlet (not shown) on the rubbery human body 1; This water inlet is provided with a dismountable seal cover (not shown), and pipeline 2 comprises transverse tube 21 and vertical tube 22, and an end and the rubbery human body 1 of transverse tube 21 are connected; The other end of transverse tube 21 and vertical tube 22 are connected; This transverse tube 21 is lucite tube with vertical tube 22, and this transverse tube 21 is 1-3cm with the caliber of vertical tube 22, and the lateral wall of this vertical tube 22 is provided with the graduation mark 3 of the height that can measure the material in this vertical tube 22.
A kind of soil pressure testing arrangement of the utility model is during test, earlier rubbery human body 1 fills with water; Be placed on the bottom or the side of wanting the soil body to be tested to rubbery human body 1 then, and vertical tube is elevated above the soil, and then the soil body is filled out on rubbery human body 1; Along with the increase of the depth of fill, the pressure that receives on the rubbery human body 1 is increasing, at this moment; Water in the rubbery human body 1 can be squeezed out to transverse tube 21 by the soil body, and in transverse tube 21 flows into vertical tube 22, when the depth of fill reaches the height of the soil body to be tested; Stop to banket; May be read into the height of water level of water in the vertical tube 22 at this moment according to the graduation mark on the vertical tube 22 3,, can converse the force of labor of water generates in the vertical tube 22 through the height of water level of water in the vertical tube 22 according to the calculation of pressure formula; Utilize soil pressure suffered on the rubbery human body 1 to equal the principle of the pressure of water generates in the vertical tube 22 simultaneously, can obtain soil pressure suffered on the rubbery human body 1.The soil pressure testing arrangement of the utility model; Avoided that type vibration wire earth pressure cell expense is higher, the problem of testing complex; Have simple in structure, easy and simple to handle, expense is low, does not receive the effect of working environment restriction, for the soil pressure test provides a kind of new approach.
Product form of the foregoing description and graphic and non-limiting the utility model and style, the those of ordinary skill of any affiliated technical field all should be regarded as not breaking away from the patent category of the utility model to its suitable variation or modification of doing.
