Abstract

As shown in Figure 1, this instrument and equipment is used to detect asphalt concrete pavement and cement concrete pavement structure depth, and the instrument and equipment mainly includes the critical pieces such as storage sand bottle, rotating frame, fastening funnel, undertaking, switch, amount sand cylinder, base, groove profile chi, rubber scraping article and fixed cover；This instrument and equipment is reasonable in design, easy to operate, portable mobile, shortens detection time, so as to be advantageous to the normal road in less influence detection section pass through and when reducing detection traffic accident probability of happening.

Description

One kind rotates quick sanding instrument

Technical field

This instrument and equipment is used for the construction depth for determining bituminous paving and cement concrete pavement, and the macroscopic view for evaluating road surface is thick Rugosity, the drainage performance of road surface and antiskid performance.

Background technology

It is existing《Highway subgrade road surface on-the-spot test code》Construction depth described in T096-1995 detects in JTG E60-2008 Problems be present in method.

Measuring sand cylinder needs manual sand loading, needs tapping three times during sand loading and stop-off strikes off, due to the difference of operator, The amount of knocking dynamics and first sand loading is also not quite similar, and artificially causes test error.

It is bulldozed with hand-held during plate spreads sand out, because the dynamics and qualification of different operating person are different, spreads out sand The not in place or sand face opened can not form more regular circle, so as to increase test error, reduce accuracy in detection..

The detection is not only inevitably carried out on the green road surface of open to traffic, and test position must position In on the wheel path of runway, detect for a long time, have impact on the personal safety of testing staff, increase the general of traffic accident generation Rate.

Each parallel test all needs again sand loading in vectorial sand cylinder, takes longer.

The content of the invention

The purpose of this instrument and equipment is to eliminate and reduce above-mentioned test error, improves accuracy in detection, shortens detection Operating time, so as to reduce vehicle to the security threat of testing staff and reduce the probability of happening of traffic accident.

The technical scheme for solving manual sand loading is：As shown in figure 1, loading enough sand in transparent storage sand bottle 1, it is first turned on out Close 6, make sand flows into naturally bottom the amount sand cylinder 7 with fixed volume it is interior to storing up untill sand face is motionless in sand bottle 1, closing switch 6, aforesaid operations can ensure that the sand in each charge weight sand cylinder 7 is almost consistent.

Solve it is hand-held be bulldozed plate stand sand and can not form the technical scheme in more regular sand face be：Driven by rotating frame 3 Four rubber strips 11, sand can be rotated into fairly regular disc, and the straight of circle is directly read by the scale 13 on base 9 Footpath.

As above described in two schemes, this instrument and equipment substantially reduces the testing inspection time simultaneously.

Brief description of the drawings

Fig. 1 is the structural representation of this instrument and equipment.

Fig. 2 ~ Fig. 7 is the critical piece enlarged diagram of this instrument and equipment.

Fig. 8, Fig. 9 are respectively rotating frame and fixed cover structural representation.

Embodiment

This instrument and equipment is described below with reference to Fig. 1 ~ Fig. 7.

As shown in Fig. 1 ~ Fig. 9, this instrument and equipment includes transparent storage sand bottle 1；For being moved easily the handle 2 of the equipment, institute Handle 2 is stated to be fixed on rotating frame 3；The rotating frame 3 by upper retainer ring 15, lower retainer ring 17,6 root posts 16 and Rotary handle 18 for rotating rotating frame is formed；As shown in Fig. 2 storage sand bottle 1 be threadably secured in fastening funnel 4 it On；Undertaking 5 immediately as shown in Figure 5 below funnel 4 is fastened, described accept is provided with three springs 10 around 5, for by screwing Three nuts on fastening funnel 4 make undertaking 5 (such as Fig. 3), upper switches 6 (such as Fig. 5), amount sand cylinder 7 (such as Fig. 7), lower switches 8 (such as Fig. 5) and base 9 (such as Fig. 6) closely connect, and prevent sand leakage；Described (such as Fig. 4) volume of amount sand cylinder 7 is 25 ± 0.15ml； As shown in fig. 6, base 9 is provided with three root posts 14, for gripping fastening funnel 4, accepting 5 and amount sand cylinder 7, and to switch 6th, switch 8 is carried out spacing；Four rubber scraping articles 11（Such as Fig. 7）It is separately fixed at four graduated groove profile chis 13 of mark（Such as Fig. 6） Below, the center of rubber scraping article 11 and the center alignment of base 9, can make to be uniformly dispersed from the sand that amount sand cylinder 7 flows out；The groove profile Chi 13 is fixed on below the lower retainer ring 17 of base 9 and rotating frame 3；Fixed cover 12（Such as Fig. 9）Inverted "L" shaped is designed as, is covered Lift in the outside of rotating frame 3, during so as to portable rotating frame 3 together with fixed cover 12, the outside of retainer ring 12 Provided with 6 stitch 19（Such as Fig. 9）, whole equipment can be fixed on road surface to be tested.

During using this instrument and equipment, load enough qualified detection sand in transparent storage sand bottle 1, by whole instrument and equipment It is placed in by approach described above on the selected test point on road surface to be measured, opens upper switches 6, is closed lower switches 8, enter sand flow Measure in sand cylinder 7, until untill the sand face in storage sand bottle 1 is motionless, close upper switches 6, opening lower switches 8, in the amount for the treatment of sand cylinder 7 Sand all flow on road surface, rotating frame 3 is rotated clockwise to untill sand face diameter no longer expands by rotary handle 18, Two sand face diameters of vertical direction are read by groove profile chi 13.
