Example 7, on the basis of the above example, this example discloses:
the leveling method of the airport channel construction equipment comprises the following steps of:
And A, installing guide rail mechanisms 1 on two sides of the earthwork 6 of the channel, and adjusting the guide rail mechanisms 1 to be horizontal.
Step B, enabling the leveling mechanism to move in a stepping mode along the guide rail mechanism through the control panel, wherein the moving distance of each step of the stepping type movement is the width of the first square frame or the second square frame, and the first square frame and the second square frame are identical in width, so that each step of movement is carried out, the second square frame covers the range which is just covered by the first square frame, the first square frame and the second square frame are lifted through the electric telescopic device in the stepping process, and the first square frame and the second square frame are placed on the surface of earthwork with set height after reaching a new position.
And C, when the leveling mechanism moves for one step, primarily leveling the surface of the earthwork along the horizontal and transverse directions through the first area segmentation primary leveling subunit, and along with the movement of the leveling mechanism, further leveling the top end of the earthwork primarily leveled by the first area segmentation primary leveling subunit through the second area segmentation primary leveling subunit along the horizontal and longitudinal directions, and finally scraping the primarily leveled surface of the earthwork through the scraping plate.
In the step C, as shown in FIG. 8, in the horizontal and horizontal preliminary leveling or the horizontal and vertical further leveling, the first partition plate and the second partition plate are inserted downward to a depth such that a part of the earthwork surface protrudes from the top ends of the first partition plate and the second partition plate, and a part of the earthwork surface is lower than the top ends of the first partition plate or the second partition plate, and the recesses in all of the first partition spaces in the first square frame or all of the second partition spaces in the second square frame are filled (because the first soil is deep, the top ends of the first partition plate and the second partition plate are easily leveled with the earthwork surface, but some earthwork protrudes from the upper ends of the first partition plate and the second partition plate at this time.
Therefore, the following steps are required), the first square frame or the second square frame is lifted up by the electric telescopic device to set the height, the first preliminary step blade or the second preliminary step blade is repeatedly used to fill the recess in the remaining unfilled first dividing space in the first square frame or the remaining unfilled second dividing space in the second square frame (for each first dividing space or the second dividing space, two cases exist after being filled, one of the two cases is filled, and no excessive earthwork exists above the dividing space, in which case no excessive earthwork can be continuously filled after the dividing space is lifted up.
In another case, the divided space is filled but the top is still filled with excess earth, the divided space is re-presented with a part of earth protruding out of the divided space by lifting, a part of earth is recessed in the divided space, the operation of filling the recess above is continued, the steps of lifting the first square frame or the second square frame by the electric telescopic device after the filling are repeated until all the first divided space in the first square frame or all the second divided space in the second square frame are filled and earth protruding out of the top end of the first divided plate or the top end of the second divided plate is not filled above the first divided plate or the second divided plate, and for the case that all the divided spaces in the first square frame are filled, the height of each first divided space after being filled is likely to be inconsistent due to uneven distribution of the top ends of earth, so that the top ends of earth are required to be truly balanced by performing longitudinal horizontal leveling by stepping.
The working principle of the invention is as follows:
the channel earthwork is uneven under preliminary state, if the channel earthwork is directly scraped with the scraping plate, even if the guide rail is arranged, the scraped part can be compact, and the part is fluffy, so that the quality of subsequent construction is affected. Therefore, the invention sets the preliminary leveling of the area division type, wherein, when the first area division preliminary leveling subunit works, the first square frame is pressed down at the top end of the earthwork, the top end of the earthwork is divided into a plurality of first division spaces by the first division plates, the earthwork amount in each first division space is different, the earthwork distribution in each part of each first division space is also different, and the earthwork in each first division space which is arranged along the transverse direction can be uniformly distributed through the preliminary leveling by the first preliminary scraping plates moving back and forth.
However, this does not represent a true preliminary leveling of the earth's top in the first square frame, as perhaps more earth in the front, less earth in the back, perhaps more in the middle, less at both ends, or otherwise, in the first square frame, and thus further preliminary leveling in the horizontal longitudinal direction is also required. When the leveling mechanism steps further, the second square frame is overlapped at the position of the original first square frame, and at the moment, the earthwork in the second square frame is the earthwork subjected to horizontal and horizontal preliminary leveling.
Then, with same principle, the second division board cuts apart into a plurality of second division spaces with the earthwork top, and the second preliminary step is scraped the flat board and is followed back and forth movement, makes level and distribute evenly along the fore-and-aft direction with the earthwork in the second division space, and this time, really realized the preliminary of earthwork top and made level, along with the mechanism of making level further step by step, the scraper blade is to the final of scraping of the earthwork top after the preliminary of making level. Because the earth top is divided from the angles of longitudinal and transverse horizontality and is primarily leveled before the scraping, the earth is uniformly distributed, the compactness after the scraping is balanced, and the quality of subsequent building construction is improved.
The soil is pushed into the first dividing space or the second dividing space through the vertical plane in the moving process of the scraping edge, and redundant soil passes through the scraping edge along the inclined plane where the isosceles triangle waist edge is located and passes through the strip-shaped through groove, so that the rear side of the advancing direction of the scraping edge is left, and therefore the situation that the soil is pushed to one end of the top of the earthwork where the first square frame or the second square frame is located in the preliminary leveling process is avoided, and the balance of the branches after the earthwork is primarily leveled is ensured.
The implementation mode of the step C is that parameters for lifting the heights of the first square frame and the second square frame each time and the times of repeated actions of the first primary scraping plate and the second primary scraping plate on each height are set through the control panel, and the first-time soil entering depth of the first square frame and the second square frame can be controlled manually.
