本発明は、１ｎ１１装道路の亀裂部分の袖イじ工法に関
する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for repairing cracks in a 1n11 road.
車軸受ｍ ｆｌＴｔの多い道路面あるいは傾斜地盤上の

輌の震動によって道路地盤沈下の進行を早めるものであ
る。On a road surface or sloping ground with a lot of car bearing mflTt! On 1lli roads, cracks occur due to excessive loads and ground subsidence. In this way, cracks in the pavement surface/- [Rainwater infiltrates through the cracks and permeates into the roadbed below, reducing the supporting capacity of the roadbed and accelerating the progress of road subsidence due to vibrations from passing vehicles. It is.

始まるものである。Moreover, a filling material mixed with asphalt (1g: 8) was used to fill the cracks that occurred on the pavement surface in the cracks (V).
Measures have been taken to restore the road by replenishing it, but since the roadbed itself has subsided, cracks will appear again and the subsidence will begin.

供するものである。The construction method of the present invention aims to fix the sinking ground by pressurizing a chemical solution that solidifies over time into the ground where the subsidence of the lower part of the cracked part of the pavement is progressing, and at the same time fixes the subsidence in the crack 1111. By doing so, the expansion of cracks and the infiltration of rainwater are prevented (υj).

CC is included. And from the top of this easy-to-use pipe (shio), it goes into the wood via a coplanar injection machine! j, (bleed 1):,
As shown in Figure 2, the molten asphalt is dispersed into the earth and sand (7) of the subsidence slab, and then pulled out.Then, the molten asphalt is applied to the cracks (2) while filling them with VC. Also, apply asphalt and apply strong asphalt sheet 1-(l/). It is also possible to prevent the sheet from becoming sticky by sprinkling sand on top of this asphalt sheet 1-(da), if necessary.

C is required to be strong enough to withstand the repeated expansion and contraction caused by vehicle traffic vibrations on the road crack surface, and K is a thick non-woven fabric made of synthetic resin fiber or glass fiber cloth as the drawing material. A suitable material is a type of lever impregnated with asphalt.

The organic material may be a completely hardened epoxy resin, a grease-resistant resin, or a flexible urethane resin.

い抜群の効果を奏ずろものである。Since the construction method of the present invention is as described above, %ll! 111, which has appeared on the straddle, by injecting a chemical solution into the underlying roadbed, the sinking ground is assimilated and reformed to increase its supporting capacity for vehicles and carts, and it also improves the crack surface. By pasting a strong asphalt sheet on the VC, it will close the cracks, prevent rainwater from entering, and also prevent the expansion of VC cracks.)
However, there is only one pond construction, and it is not seen in the repair work that has been suggested to have good durability after repair work.
It has an outstanding effect.
