Abstract
The utility model discloses a static-pressure-type device for measuring the compaction degree of a layered filled embankment. The static-pressure-type device comprises a rack, a dowel bar and a control display. The rack is composed of an upper beam, a lower beam, a left beam and a right beam. The left and lower beams and the left and right beams are fixedly connected to form a framework. A support beam is arranged between the left and right beams. A gear set is arranged on the support beam. A toggle handle is disposed on the gear set. The upper beam, the lower beam and the support beam are provided with a through hole, respectively. The dowel bar penetrates through the three through holes and is engaged with the gear set. A sensor is disposed at the bottom of the dowel bar and is connected with the control display. The static-pressure-type device of the utility model measures the compaction degree of an embankment through the penetration resistance which is measured by static sounding. In addition, the static-pressure-type device is precise and rapid in measurement and is convenient to carry.

Technical field
The utility model relates to the measurement mechanism of Subgrade Compaction, especially a kind of static pressure type placement in layers embankment degree of compaction measurement mechanism.
Background technology
In highway embankment placement in layers work progress; The compaction rate of soil body placement grinding explicitly calls for; Be the requirement of degree of compaction, adopt sand replacement method, water flood, nucleon density appearance method in some engineerings, and these methods or detection efficiency is low; Cost is high, detects Subgrade Compaction quickly and accurately and will be the engineering staff and expect the problem that solves.
At present the cone penetration test result is usually used in the aspects such as differentiation and allowable bearing capacity of single pile calculating of drafting, the silt liquefaction of discriminating, the soil layer block diagram of soil classification, not have and the measurement of Subgrade Compaction connects.
The utility model content
The purpose of the utility model provides a kind of penetration resistance test Subgrade Compaction of utilizing static sounding, measures static pressure type placement in layers embankment degree of compaction measurement mechanism accurately and fast.
For realizing above-mentioned purpose, the technical scheme that the utility model adopted is: a kind of static pressure type placement in layers embankment degree of compaction measurement mechanism comprises support, dowel bar and control display; Said support is made up of upper beam, underbeam, Zuo Liang, right beam; Last underbeam, left and right beam are fixedly connected to form framework, between left and right beam, are provided with brace summer, on brace summer, are provided with gear train; On gear train, be provided with and stir handle; Last underbeam and brace summer are respectively equipped with through hole, and dowel bar passes three through holes and is meshed with gear train, are provided with in the bottom of dowel bar and control the sensor that display is connected.
Preferably, said gear train is symmetricly set on the both sides of dowel bar spire.
Preferably, said sensor is conical sensor.
The utility model is fixed in road bed to be measured with frame rack through ground nail after adopting said structure, and the level(l)ing bubble adjusting level on underbeam surface is arranged; Hand brake is stirred handle, amplifies power through gear train, forces sensor probe to be pressed in the roadbed, by the display reading, calculates Subgrade Compaction; Functional relation through pressure and degree of compaction calculates degree of compaction, and the result accurately and reliably; And it is easy to carry.The utility model utilizes the method for testing of the penetration resistance degree of compaction of obtaining roadbed accurately and fast of static sounding, and this method effectively reduces the expense of test, and is easy to operate, quick, saved the time.
The embankment degree of compaction measurement mechanism of more traditional core cutter method, sand replacement method, nuclear moisture and density meter method has following obvious effects:
(1) easy for installation: be placed in road bed to rectangle support, leveling gets final product;
(2) test is quick and precisely: operation manually, do not need the electric power support, and be fit to field work.Directly reading calculates, and test speed is fast;
(3) safety, reliable: device volume is little, in light weight, and is easy to carry, safe and reliable, the electronics collection, and data are accurate.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further explain:
Fig. 1 is the utility model structure chart.
Among the figure: 1 support, 11 put the beams in place, 12 underbeams, 13 left beams, 14 right beams, 2 dowel bars, 21 spires, 3 control displays, 4 brace summers, 5 gear trains, 6 stir handle, 7 through holes, 8 sensors, 9 ground nails.
The specific embodiment
Shown in Figure 1, the static pressure type placement in layers embankment degree of compaction measurement mechanism of the utility model comprises support 1, dowel bar 2 and control display 3; Said support 1 is made up of upper beam 11, underbeam 12, left beam 13, right beam 14; Last underbeam 11,12, left and right beam 13,14 are fixedly connected to form framework, in left and right beam 13, be provided with brace summer 4 between 14, on brace summer 4, are provided with gear train 5; On gear train 5, be provided with and stir handle 6; Last underbeam 11,12 and brace summer 4 are respectively equipped with through hole 7, and dowel bar 2 passes three through holes 7 and is meshed with gear train 5, are provided with in the bottom of dowel bar 2 and control the sensor 8 that display 3 is connected.The gear train 5 of present embodiment is symmetricly set on the both sides of dowel bar 2 spires 21.Sensor 8 is conical sensor.
The use step is following:
(1) is fixed in the road bed of being surveyed to frame rack 1 through ground nail 9;
(2) the adjustment level(l)ing bubble makes the device level, and the probe of adjustment cone-shaped sensor 8 vertically is contacted with road bed;
(3) shake and stir handle 6,, be pressed into the roadbed certain depth to cone-shaped sensor 8 probes through the amplification of gear train;
(4) survey the data of reading to control display, calculate Subgrade Compaction, design formulas can be derived the calculation expression that is suited to local conditions by induction.
The utility model utilizes the method for testing of the penetration resistance degree of compaction of obtaining roadbed accurately and fast of static sounding, and this method effectively reduces the expense of test, and is easy to operate, quick, saved the time.More traditional core cutter method, sand replacement method, the nuclear moisture and density meter method is simple in structure, easy to operate, accuracy is high, and cost is low, and is succinct fast, sturdy and durable, is fit to very much the fast detecting that height is filled out embankment placement in layers degree of compaction.
The above is the preferred implementation of the utility model; Certainly can not limit the interest field of the utility model with this; Should be understood that; For those skilled in the art, the technical scheme of the utility model is made amendment or is equal to replacement, do not break away from the protection domain of the utility model technical scheme.
