[detailed description of the invention]
Below in conjunction with the accompanying drawings the utility model is described in further details.
As it is shown in figure 1, the utility model includes floorings 1, floorings 1 are divided into some regions, in one of region
It is provided with sandy soil 3, in another block region, water-proof tack coat 4 is set, is provided with and bridge in the upside of sandy soil 3 and water-proof tack coat 4
The equivalently-sized pave-load layer of panel 12；Gap 5 is left between floorings 1 and pave-load layer 2.The utility model considers large-span steel
The engineering of bridge is actual, the limitation of the existing experiment material in Binding experiment room, uses steel plate simulation Steel Bridge plate 1, pitch coagulation
Soil is as pave-load layer 2, and emulsified asphalt, as water-proof tack coat 4, makes the sample of correlation type, and wherein each material can also root
Choose according to actual conditions.
Being divided into three pieces of regions arranged side by side in the utility model on floorings 1, sandy soil 3 and tack coat 4 are arranged on adjacent
In region, and water-proof tack coat 4 is positioned at the region of centre；Also can be further added by region as required, thus form more boundary
Face.
The floorings 1 of the utility model bottom surface are taken off, i.e. forms the interface that pave-load layer 2 contacts with air 6, such as Fig. 2 institute
Show.
Water in the coated on bottom side removing floorings 1, can form the interface that pave-load layer 2 contacts with water layer 7, as shown in Figure 3.
The main course of work of the utility model and principle: the pave-load layer 2 of bridge floor and floorings 1 bonding defect mainly have with
Lower four kinds: the material of (1) water-proof tack coat 4 does not spray uniformly, some places be not sprayed onto directly formed bituminous concrete-
Steel interface；(2) bonding interface of water-proof tack coat 4 does not clean out formation bituminous concrete-sandy soil interface；(3) work to tight deadlines
Interface has water or rainy day construction to form bituminous concrete-water termination；(4) adhesion strength is inadequate, viscous under external force or temperature action
Junction interface separates and forms bituminous concrete-Air Interface.
In order to simulate the relativity of various defect and bonding good interface, first surface of steel plate is cleaned up and dry, will
Steel plate is put in rolling forming machine grinding tool, and surface of steel plate is divided into trisection, coats sandy soil 3 on the area of the left side 1/3, in
Between 1/3 area be uniformly coated with emulsified asphalt formed water-proof tack coat 4, then spread on sandy soil 3 and water-proof tack coat 4 with entirely
The identical bituminous concrete of plate size forms pave-load layer 2, uses rolling forming machine by bituminous concrete roller-compaction.So steel
The left side 1/3 area of plate can simulate bituminous concrete-sandy soil interface that bonding interface does not clean out formation, middle 1/3 face
Amassing and can simulating bonding good interface, the right 1/3 area is hole 5, and formation is used for simulating water-proof tack coat 4 material and is not sprayed onto
Interface.After supersonic reflectoscope detection signal, steel plate is removed, bituminous concrete-Air Interface can be formed, if going
Fall water in the bituminous concrete coated on bottom side of steel plate, bituminous concrete-water termination can be formed.I.e. one sample can carry out five kinds of boundaries
The test in face, both cost-effective, save the time again.
The utility model can realize that a kind of sample simulates 5 kinds of bridge deck pavement bonding experiment for non-destructive testing experiment interfaces, design
Rationally, reliability is higher, and cost is relatively low, it is simple to promote the use of.
