Description
Technical field
The utility model relates to a kind of luoyang spade, particularly a kind of luoyang spade measuring lateral earth pressure.
Technical background
In the design of geotechnical engineering, lateral pressure coefficient is a very important parameter, and in foundation ditch, tunnel and subway engineering, lateral pressure coefficient is all the parameter that must provide.General in geotechnical investigations, lateral pressure coefficient is measured in multiplex flat chisel test etc.But this process is consuming time, and cumbersome.In rock mass mechanics, lateral pressure coefficient is horizontal compressive stress and the ratio of vertical compressive stress, and generally, vertical compressive stress ratio is easier to obtain, and be average severe and be multiplied by the corresponding degree of depth, the direct measurement of lateral earth pressure is then more difficult.If when technician samples, just can obtain lateral earth pressure quickly and easily, then can offer convenience to whole design process.
Luoyang spade is the instrument that fetches earth that geologist commonly uses, but its function is comparatively single, is mainly used to extract soil sample.
Utility model content
For solving the problems of the technologies described above, the utility model provides a kind of luoyang spade directly can measuring lateral earth pressure.The utility model adopts following technical scheme:
Comprise shovel head and spade, described shovel head and spade are threaded; Described shovel head position arranges a cavity, and cavity is built-in with pressure sensitive sheet; The top of described shovel head is provided with the spacing partition of the soil body, and the spacing partition of the soil body is fixed with pressure sensor; Be provided with the duct connecting cavity and the spacing partition top of the soil body in the interior of described shovel head, in duct, lay the wire of Bonding pressure sensing chip and pressure sensor; Described pressure sensor is equipped with antenna, controls receiver wireless connections by antenna and ground; Ground is utilized to control the receiver measurement of controlled pressure sensor to soil pressure and the transmission of data.
The outer wall of described cavity is flexible metal, and inwall is consistent with the material of shovel head.
The outer wall surface of described cavity is in same plane with shovel head wall outer surface.
Described pressure sensitive sheet is attached to inwall side, and just touches with outer wall, ensures that at the numerical value of the state downforce sensing chip not having external pressure be zero.
Described ground controls receiver and is provided with display screen, directly can show measured lateral earth pressure value.
Described spade comprises to be measured spade and is connected spade; The outer wall of described measurement spade longitudinally indicates scale value; Described connection spade is threaded by the short connection spade that many length is known and forms.
One end of described connection spade is connected with shovel head thread; The other end of described connection spade is threaded with measurement spade; Described connection spade all locates below ground level.
The length of described shovel head is 20-50 centimetre, and diameter is 2-20 centimetre.
The beneficial effects of the utility model are:
Cavity is set at the sidewall of shovel head, and at the built-in power of the bleeding off pressure sensing chip of cavity, the inwall of cavity is consistent with the material of shovel head, and this structure can ensure the normal digging function of luoyang spade; Cavity outer wall is flexible metal, and outer wall surface is in same plane with shovel head wall outer surface; Described pressure sensitive sheet is attached to inwall side; and just touch with outer wall; ensure that at the numerical value of the state downforce sensing chip not having external pressure be zero, this feature both can protect pressure sensitive sheet from damage, can ensure again the Measurement accuracy to lateral earth pressure.
The spacing partition of the soil body is set on the top of shovel head and can limits the length of getting soil sample, and the pressure sensor on its top is played a protective role.Wire is placed in the duct of shovel head interior, even if under the mal-condition that moisture content is higher, still can guardwire from infringement.Utilize wireless device to control to receive data, surveying work can be realized, and convenient.
Connect spade to be threaded by the short connection spade that many length is known and to form, can regulate easily and fathom, the outer wall measuring spade longitudinally indicates scale value, makes measurement numerical value more accurate.
Luoyang spade is instrument conventional in geologic prospect, only carry the lateral earth pressure value that luoyang spade just can measure the soil body and can omit the correlation test carrying heavy instrument, and just can measure lateral earth pressure value in passing in the process of reconnoitring in drill hole sampling, greatly facilitate explorer, save a large amount of work, improve operating efficiency.
Accompanying drawing explanation
Fig. 1 is the structural representation of luoyang spade.
Wherein, Reference numeral is respectively: 1 shovel head, 2 spades, 3 cavitys, 4 pressure sensitive sheets, the spacing partition of 5 soil body, 6 pressure sensors, 7 ducts, 8 wires, 9 antennas, and 10 ground control receiver, 11 display screens, and 12 measure spade, and 13 connect spade, 14 scales.
Detailed description of the invention
Comprise shovel 1 and spade 2, described shovel head and spade are threaded; Described shovel head position arranges a cavity 3, and cavity is built-in with pressure sensitive sheet 4; The top of described shovel head is provided with the spacing partition 5 of the soil body, and the spacing partition 5 of the soil body is fixed with pressure sensor 6; Be provided with the duct 7 connecting cavity and the spacing partition top of the soil body in the interior of described shovel head, in duct, lay the wire 8 of Bonding pressure sensing chip 4 and pressure sensor 6; Described pressure sensor is equipped with antenna 9, controls receiver 10 wireless connections by antenna 9 and ground;
Described ground controls receiver and is provided with display screen 11, directly can show measured lateral earth pressure value.
Described spade comprises to be measured spade 12 and is connected spade 13; The outer wall of described measurement spade longitudinally indicates scale 14; Described connection spade is threaded by the short connection spade that many length is known and forms.
During use, determine the degree of depth needing to measure lateral earth pressure, according to pressure sensitive sheet to shovel head be connected spade junction distance, connect the radical of spade and measure the reading of spade, determine when required measuring position, measure spade and horizontal plane to maintain an equal level the scale at place, this scale is Measurement scales; Fetching earth for the last time before owing to dig 5 centimeters and completing measurement.Measurement spade of holding with a firm grip will shovel head vertical depression, avoid the disturbance to the soil body as far as possible.When the scale that measurement spade and horizontal plane maintain an equal level is Measurement scales, stop pressing down.Open and regulate floor-treating device 6, making pressure sensitive sheet in running order, now, the lateral earth pressure value that display pressure sensitive sheet is measured by display screen 11, when numerical stability, record numerical value, this is final lateral earth pressure value.
