Description

A kind of device of quick detection cement stabilization crushed rock base course intensity

Technical field

The utility model belongs to Road Bed Compactness detection technique field, and in particular to a kind of quickly detection cement stabilization The device of crushed rock base course intensity.

Background technique

Cement stabilized macadam is to make aggregate with graded broken stone, using a certain number of cementitious materials and enough mortar volumes The gap of filler aggregate paves compacting by embedded squeezing principle.Its compactness is close to compactness, and intensity is mainly by the embedded squeezing between rubble Lock knot principle, while the gap for thering are enough mortar volumes to carry out filler aggregate.Chance rain is not muddy after cement stabilized macadam survives, table Face is solid, is the ideal base material of high class pavement.But the performance of cement stabilized macadam must by reasonably form design and Construction control obtains, to avoid its shortcoming, if property is crisp, non-deformability is poor, in temperature and humidity variation and load action Under be also easy to produce crack, so as to cause road surface early damage, shorten the service life of road.

Cement stabilized macadam base intensity index is the important indicator of evaluation path base performance, therefore is completed in construction Afterwards, its intensity is detected.For cement stabilized macadam, its intensity detection is product to be sampled by paving site, through standard at present Its unconfined compressive strength is measured after maintenance to realize, the quality of cement stabilized macadam base mainly by the intensity of test specimen come Evaluation.Traditional strength detecting method will be sampled by construction site, and sample is fabricated in laboratory, is then tested and is divided Analysis, finally just obtains a result.The process is complicated, spends manpower and time more, and the production to sampling, indoor standard test specimen There are higher precise requirements, is easy to produce error.In view of this, a kind of measuring instrument should be provided, the prior art is solved Present in the above problem.

Its intensity detection is to sample product by paving site, measure its unconfined compressive strength after standard curing at present It realizes, the quality of cement stabilized macadam base is also mainly evaluated by the intensity of test specimen.This strength detecting method is wanted It is sampled by construction site, sample is fabricated in laboratory, is then tested and is analyzed, is finally just obtained a result.The process Complexity spends manpower and time more, and has higher precise requirements to the production of sampling, indoor standard test specimen, holds It is also easy to produce error.

Specific embodiment

In order to make those skilled in the art better understand the utility model, with reference to the accompanying drawing with implementation method to this reality It is described in further detail with novel.

In figure: 1- driving mechanism；2- bracket；3- bracket adjusts spiral；4- drill bit；5- drill；6-level meters；7- disk.

As shown in Figs. 1-5, the device of the quick detection cement stabilization crushed rock base course intensity of the utility model, including, driving Mechanism 1 (such as lifting handle 1), bracket 2, drill bit 4, drill 5, it is also preferable to include level meters 6.Wherein bracket 2 has multiple Brace and the disk 7 for being connected to support arm top, lifting handle 1 are arranged on the disk of bracket 2, setting in lifting handle 1 There is screw thread, rotate and connect with thread spindle, the thread spindle passes through the disk lower end and connect with drill bit 4, the setting of 4 lower end of drill bit There is drill 5.It is additionally provided with level meter 6 on the disk 2, for measuring the turnning circle of lifting handle 1.Preferably, the branch Brace is retractable structure comprising nested arm is provided with bracket and adjusts spiral 3, described for unclamping or fastening The adjacent arm of support arm.When work, described device is placed in ground, the drill 5 is contacted with the base to be detected, so Afterwards by rotation and lifting handle 1, thread spindle is driven to move down, so that drill bit moves down.

The preferably described driving mechanism 1 can be rotated with motor driven.

In other scheme, as shown in Figures 4 and 5, the drill 5 is made of multiple blades 8, multiple blade symmetry distributions, 8 blades are shown in figure, blade is elongate configuration, and its underpart and outer rim are provided with blade.

As shown in fig. 6, the gauge diameter of drill bit 4 is less than the diameter of drill 5 in other scheme, the drill includes more A sharp knife edges 51, and the row's of being formed with stone cistern 52 on the side wall of drill 5, the small stone for going to generation can be along row's stone cistern 52 are upwardly into the space between bar portion and drilling.Preferably, the angle of row's stone cistern 52 with respect to the horizontal plane is 30-60 Degree.In preferred scheme, the inside of the drill has space, and row's stone cistern 52 is connected to the space, the discharge Stone can enter the space in.

Illustrate the embodiments of the present invention below, before measuring, in advance in laboratory, repeatedly measures different brackets The cement stabilized macadam base of intensity can be inserted into the depth of base at hollow boring bit multi-turn rotation (such as 50 circles), reduce test Contingency, and data are handled, record is performed, intensity is established and drill pierces the corresponding relationship of base's depth, as in-site measurement Foundation.

Take ground at random at the construction field (site), the good device of frame makes its level, is parked in drill 5 just on base face.Instrument adjustment After good, start to measure, at the uniform velocity the shake pre- fixing turn of lifting handle 1 one (such as 50 circles), preferably passes through the record rotation of level meter 6 How many circle turned, drill 5 is rotated down.After 50 circles, stop shaking lifting handle 1, with vernier caliper measurement drill bit 4 on ground On height, just show that drill 5 pierces the depth on ground.No less than 3 times measurements are carried out in measurement tests and record data, It is averaged, to the resulting data in laboratory are impinged upon, that is, knows the intensity of live cement stabilized macadam base.

The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art For art personnel, without departing from the principle of this utility model, several improvements and modifications can also be made, these improve and Retouching also should be regarded as the protection scope of the utility model.In addition, although being used some specific terms in this specification, this A little terms do not constitute any restrictions to the utility model just for the sake of facilitating explanation.
