Abstract

A scour-prevention farm road pavement method is provided to reduce construction and maintenance expenses and to prepare for the danger of accidents by developing a farm road pavement capable of blocking farmers' grievance in a small scale farm road pavement. A scour-prevention farm road pavement method comprises the steps of preparing the existing farm road before placing concrete, pit-excavating for constructing a mat, a subbase course(2), etc., installing a subbase layer after constructing a mat on the ground, and placing concrete to the top of right and left farm roads in the various shape according to the surroundings, and then arranging.

Description

Preservation down concrete pavement

1 is a process diagram briefly showing a conventional farm road concrete construction method.

  Stage 1: Existing Farm Stage 2: Dig Stage 3: Subsidiary Base Laying after Mat Construction

  Step 4: Clean up and finish after pouring concrete

Figure 2 is a view showing a shape crushed by a conventional farm road concrete construction method.

  2-1 is a drawing that farmers crushed artificially to secure land

  2-2 is a drawing that was naturally crushed in the absence of the ground due to insufficient land security.

  Figure 2-3 is a drawing without a ground without sufficient land security

3 is a view according to an embodiment of the present invention.

Concrete pavement is made of 1. digging 2. soft ground treatment using soft ground treatment method.

The present invention as a security method to the disadvantages of the existing farm road concrete pavement (2-1), the existing pavement is not artificially crushed by the greed of the land of the farmers, or the site is not secured by the soil subsidiary base is naturally settled and natural crushed concrete concrete In many cases, the concrete is separated from the subbase or soil (2-2) .If the concrete sphere and the soil or subbase are separated, the load causes a crack in the concrete sphere and risks a safety accident. Is exposed to. In addition, maintenance costs have been incurred, many problems have emerged. When the farmland and concrete spheres are the same height or slightly higher (2-3), the optimum compaction of the subbase is not possible in the soft ground, so the water may move between the subbases, which impedes farming. In many cases, civil complaints were requested to make the retaining wall between the concrete road and the concrete road. However, the retaining wall is a construction method suitable for high loads, and the construction cost is significantly higher than that of the present invention. It is feed. The present invention relates to a method for preventing the crushing of farmland concrete pavement, while constructing the concrete sphere to a sub-base or below the top of the farmland, depending on the surrounding environment to construct a concrete, inverted a, upside down c, etc. Method, by attaching a natural stone or concrete block directly to the farm concrete sphere (FIG. 5), to prevent crushing and to repair the existing farm, after drilling the concrete sphere and using the present invention in the gap between the concrete sphere and the auxiliary base layer The present invention relates to a method of inserting concrete and repairing or placing a small amount of concrete thereon. As a result, the present invention relates to a method for repairing existing farm roads, which can save costs and construction periods caused by demolition of existing farm roads.

The present invention relates to a method for preventing the crushing of farmland concrete pavement in the method of constructing a concrete sphere in the form of a, inverse a, upside down c, etc., depending on the surrounding environment to the sub-base part or the lower part while paving the farmland concrete pavement. It is about.

By attaching natural stone or concrete block directly to the farm concrete sphere (Fig. 5), to prevent crushing and to repair the existing farm, after repairing the concrete sphere after using the present invention by inserting the concrete in the gap between the concrete sphere and the auxiliary base layer repair Or to lay a small amount of concrete on top of the existing farm road repair method that can save the disposal, construction costs and construction period caused by the demolition of the existing farm road.

If all the people are expected to build public offices, they will raise their complaints if there is any inconvenience. Therefore, it is a way to reduce construction costs and maintenance costs and to prepare for safety accidents by developing farm pavement that can block civil complaints from small pavement pavement.

Claims (2)

It is about preventing the crushing and the order of concrete pavement of farm road. The agricultural road pavement construction method is characterized by consisting of a construction method that can save air or construction costs in response to. Install natural stone or concrete block directly on the farm concrete sphere to prevent crushing, or when repairing the farm, perforate the concrete sphere after using the present invention and repair the concrete by inserting the concrete into the gap between the concrete sphere and the auxiliary base layer. Or a small amount of concrete on it.
