Description
Technical Field
The invention relates to the technical field of pavement intensity detection, in particular to a device for detecting the intensity of a regenerated pavement of construction waste.
Background
The construction waste refers to dregs, waste soil, waste materials, sludge and other wastes generated in the process of constructing, laying or dismantling various buildings, structures, pipe networks and the like by construction units or individuals. The main components are as follows: engineering dregs, decoration garbage, demolition garbage, engineering slurry, dregs, concrete blocks, crushed stone blocks, brick and tile fragments, waste mortar, slurry, asphalt blocks, waste plastics, waste metals, waste bamboo and wood and the like. The refractory high polymer material, harmful heavy metal elements and the like not only cause harm to surrounding residents, but also pollute underground water, destroy soil structure, cause subsurface subsidence, prevent vegetation from regenerating and the like.
To solve the above problems, the prior art has developed the following construction waste recycling pavements:
CN202221022994.3 discloses a highway structure based on construction waste recycled material, which comprises a roadbed, a subbase layer and a surface layer which are piled up sequentially from bottom to top; the subbase layer is a cement stabilized building rubbish recycling material layer; the base layer is a cement stabilized building rubbish recycling material layer.
The primary technical index of the design, construction and quality assessment of the pavement as a structure bearing dynamic load actions such as impact, vibration, abrasion and fatigue is the flexural strength, and the maximum load which can be born by the unit area of the trabecula of the concrete under the action of bending force is the flexural strength of the concrete. The flexural strength is the trip guarantee of the cement concrete pavement under the heavy traffic condition, so the magnitude of the flexural strength of the cement concrete can not meet the design requirement, the overall quality and the service life of the pavement are directly influenced, and the flexural strength plays a key role in improving the overall quality of pavement design and engineering projects.
In summary, it is known that the pavement strength needs to be detected, and the existing pavement strength detection method includes a core drilling sampling method and a nondestructive detection method, wherein the core drilling method has the advantages of intuitiveness, accuracy and reliability, but has the defects of high cost, long time consumption, local damage to concrete and the like in detecting the concrete, so that a large amount of core drilling sampling is often limited. The nondestructive testing generally uses more testing methods of deflection values (deflection generally refers to total vertical deformation values (total deflection) or vertical rebound deformation values (rebound deflection) generated by the wheel gap positions of roadbed or pavement surface under the load action of a specified standard vehicle, the unit is 0.01 mm), the most currently used are a Beckmann beam method, an automatic deflection meter, a drop hammer deflection meter (FWD) and the like, wherein the rebound deflection measured by the Beckmann beam method is static deflection, the running speed of the automatic deflection meter is very slow, the measured rebound deflection is close to the static deflection, the drop hammer deflection meter generates corresponding equivalent load by freely falling down of a drop hammer with a certain weight, deflection generated by the loading mode is very similar to the action of a running vehicle on the ground, dynamic deflection basin data can be obtained, and the actual situation of fast running of the vehicle is simulated, so that the nondestructive testing is preferred.
Drop deflectometers are classified into hand-held, vehicle-mounted and trailer-mounted, wherein the vehicle-mounted and trailer-mounted are more fitted to the actual scene, so that the drop deflectometers are more popular, but the existing vehicle-mounted or trailer-mounted drop deflectometers have the following defects in the test:
1. The test is stopped when the test is needed, and the test efficiency is reduced by stopping for at least 40 seconds each time, so that the test is not suitable for continuous test of long road sections;
2. the test pavement needs no pit and garbage, so that the test area is limited;
3. The temperature and humidity on the road surface are too high to influence the test result, so that the accuracy of the test result is reduced.
