A road level measuring instrument

technical field

The utility model belongs to the technical field of municipal engineering, in particular to a road level measuring instrument.

Background technique

Road construction is the foundation of national economic development, which can promote the progress and development of society. As the traffic volume continues to increase, the congestion phenomenon is becoming more and more serious. The development of urban express roads is the top priority, but the implementation of main road projects is also critical to the technical conditions. It is relatively strict, and one of the most important technical conditions is the overall smoothness of the road surface, but in the past, there will be many uneven points after the road surface is completed, which brings a lot of inconvenience to people's travel.

Utility model content

The utility model aims at the deficiencies of the prior art, and provides a road level measuring instrument which can quickly adjust the smoothness of the road surface and is easy to operate.

In order to solve the above-mentioned technical problems, the utility model is solved by the following technical solutions: A road level measuring instrument, comprising a level scale head, a fixed block, a slide rail, a reference platform, a connecting pin, a fixed head, and a connecting rod, the level The scale head is set on the slide rail, and the slide rail fits on the top of the fixed block. The fixed block is fixed on both sides of the connecting rod. The connecting rod and the fixed head are consolidated into one body. The platforms are mated and connected together, and the reference platform is placed on the measured plane.

As a further improvement of the utility model, the horizontal scale head is placed in the middle of the slide rail, and the horizontal scale head is provided with a vertical joint.

As a further improvement of the utility model, there are two fixing blocks.

As a further improvement of the utility model, the length of the slide rail exceeds the distance between the two fixing blocks.

As a further improvement of the utility model, there are two reference platforms.

Beneficial effects: Compared with the prior art, the utility model has the following beneficial effects: the road level measuring instrument of the utility model is placed on the road surface to be measured, and the surface flatness of the exit road can be converted through the inclination angle of the horizontal scale head, which can be measured in time. The leveling of the pavement can prevent engineering problems that are difficult to correct in the later stage. At the same time, the overall structure of the level measuring instrument is simplified, easy to operate, and can improve the progress of the project.

detailed description

Referring to Fig. 1, a road level measuring instrument comprises a horizontal scale head 1, a fixed block 2, a slide rail 3, a reference platform 4, a connecting pin 5, a fixed head 6, and a connecting rod 7, and the horizontal scale head 1 is set on the slide rail 3 Above, the slide rail 3 fits on the top of the fixed block 2, the fixed block 2 is fixed on both sides of the connecting rod 7, the connecting rod 7 is integrated with the fixed head 6, and the fixed head 6 is connected with the reference table 4 through the connecting pin 5. Together, the reference table 4 is placed on the measured plane.

The horizontal scale head 1 is placed in the middle of the slide rail 3, and the horizontal scale head 1 is provided with a vertical joint 11. The horizontal scale head 1 can correctly measure the angle of the road surface inclination, and avoids placing the horizontal scale head 1 on the edge of the slide rail 3. Errors are caused to the measurement of the inclination angle of the road surface. The angle of inclination of the road surface can be quickly converted through the opening and closing angle of the vertical joint 11 and the horizontal scale head 1, and remedial measures can be implemented in time.

There are two fixed blocks 2, which can ensure that the measured value of the horizontal scale head 1 is the actual value of the inclination of the road surface, and prevent errors in the measurement of the horizontal scale head 1.

The length of the slide rail 3 exceeds the distance between the two fixed blocks 2, so as to prevent the horizontal scale head 1 from falling during the measurement, causing errors in the measurement accuracy of the horizontal scale head 1.

There are two reference platforms 4, which can play a very good stabilizing effect, and also accurately reflect the length of the measured road section.

After the road project is implemented, the road level measuring instrument is placed on the measured road surface, and the two reference platforms 4 can limit the length of the measured road surface, and then the fixed head 6 is connected together with the reference platform 4 by using the connecting pin 5, so that The operator is convenient for loading and unloading, the fixed block 2 is fixed on both sides of the connecting rod 7, and the connecting rod 7 and the fixed head 6 are consolidated into one body, which improves the stability and prevents the shaking of the horizontal scale head 1 from measurement errors, and the slide rail 3 fits together The top of the fixed block 2 can be easily removed after measurement, and the angle of inclination of the road surface can be quickly converted through the opening and closing angle of the vertical joint 11 and the horizontal scale head 1, which provides technical support for later remedial measures.

In summary, the road level measuring instrument of the utility model is placed on the road surface to be measured, and the surface smoothness of the road can be converted through the inclination angle of the horizontal scale head, and the road surface can be leveled in time to prevent engineering problems that are difficult to correct in the later stage. At the same time, the overall structure of the level measuring instrument is simplified, easy to operate, and can improve the progress of the project.
