Abstract
The utility model provides a device for testing bonding between highway surface layers, which belongs to the technical field of highway traffic detection instruments and structurally comprises a base, a fixed steel plate seat and a sliding steel plate seat. The fixed steel plate seat is vertically arranged on the base, a fixed bearing sleeve is arranged on the fixed steel plate seat, grooves are respectively arranged on two edges of the fixed steel plate seat, the sliding steel plate seat is arranged in the grooves and in sliding connection with the fixed steel plate seat, and a movable bearing sleeve is arranged on the sliding steel plate seat. A fixed testing sleeve is sleeved in the fixed bearing sleeve, and a movable testing sleeve is arranged in the movable bearing sleeve. The device for testing the bonding between the highway surface layers is reasonable in design, simple in structure, strong in rigidity, safe, reliable, convenient to use and easy to process and maintain, enables a tested piece not to have stressed deflection in the straight-scissoring test process, and can effectively improve testing precision and accuracy degree of test results.
Description
Technical field
The utility model relates to highway communication and detects apparatus technical field, specifically a kind of highway pavement interlaminar bonding proving installation.
Background technology
General; The interlayer of highway pavement (between asphalt concrete layer and the asphalt concrete layer, between cement concrete pavement and the bituminous concrete finishing coat, between the bridge deck pavement) connection problem is the problem that highway circle is extremely paid attention to always; Between China's asphalt concrete layer and the cement stabilizing layer and the interface layer between the asphalt concrete layer bonding relatively weaker; Be in fully and slide and totally continuous intermediateness, between layer and the layer through contacting transmission stress.Like this; The actual working state of bituminous pavement and design theory duty are inconsistent; Thereby directly have influence on estimating of road surface usability; Should adopt rational contact model to describe the interlayer state, thereby analyze the mechanical response of road surface under actual working state, reach above purpose need reasonably calculate the actual contact situation of interlayer.At present; Being used to test ground surface material and road surface structare layer and bridge deck pavement shearing strength at intersection, to cut the test method and the instrument kind of ability a lot, but all there are some problems in many instruments, as: involve great expense; Need be equipped with special loading pressurized equipment; Bulky being not easy to carried, and complicated operation can only supply minority to have the mechanism that specializes in of economic capability to use.
Summary of the invention
The technical assignment of the utility model is the deficiency that solves prior art, and a kind of highway pavement interlaminar bonding proving installation is provided.
The technical scheme of the utility model realizes by following mode; This highway pavement interlaminar bonding proving installation, its structure comprises base, fixation steel plate seat, sliding steel plate seat, is vertically installed with the fixation steel plate seat on the base; The fixation steel plate seat is provided with decides the load sleeve; Two edges of fixation steel plate seat are respectively arranged with groove, and the sliding steel plate seat is arranged in the groove and with the fixation steel plate seat and is slidingly connected, and the sliding steel plate seat is provided with moving load sleeve.
Decide to be socketed with in the load sleeve location survey examination sleeve, be provided with moving test cartridge in the moving load sleeve.
The beneficial effect that the utility model is compared with prior art produced is:
This highway pavement interlaminar bonding proving installation is reasonable in design, simple in structure, rigidity is strong, safe and reliable, easy to use, be easy to processing and safeguard; The use of location survey examination sleeve, moving test cartridge; Test block is stuck in decides in load sleeve and the moving load sleeve; Make test block no stressed deflection in the staight scissors test process, more can effectively improve measuring accuracy, improve the accuracy of test result; This device can provide vertical pressure by real-time loading equipemtns such as hydraulic dynamometers, and with respect to domestic other shearing equipments of the same type, volume is littler, is convenient to move, and operates simple and fast more, and the cost reduction is convenient to promote the use of in construction department.
