Get the best understanding. BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is a block diagram showing the construction process in a portion of the depth maintenance method of the rigid pavement of the present invention. The construction process basically includes: (1) Defining the scope of maintenance: The ideal concrete removal area is 5~15 cm (2~6 吋) outside the defect area, and the preferred minimum maintenance length is 25cm (10吋). 10cm (4吋). Use a diamond blade to cut the sawholes and use a chisel to remove the concrete from the pits. In order to facilitate the removal of mixed concrete within the scope of repair, the cutting depth is at least 5 cm (2 ft) deep, and the cutting path should be straight and perpendicular to each other to form a vertical corner and a service interface perpendicular to the surface of the plate. Helps prevent the damage from expanding. Removal of unscreed concrete in the service area should be removed from the center to the edge and care should be taken to avoid damage to the sawing boundary and the stabilizing concrete below the broken bottom. Then, by hand hammer or sand blasting, a rough bonding surface is produced, and the maintenance area is surely cleaned. Use a sand blasting machine to remove particles, oil, garbage, tar stains and other contaminants in the patch to increase the roughening of the repaired surface and increase the adhesion of the 200825250. Water jets or high-pressure jets can also be used. (2) Implanting the reinforcing material: The reinforcing material is implanted in the maintenance pit, and a) is drilled at a fixed point in the maintenance pit and the hole diameter is required to be drilled. b) Use a hole brush to remove the larger pieces, and then let the high-pressure air nozzle blow out the powder. At least repeating the ## wall will affect the gripping force of the planting rubber. Therefore, it is often confirmed after drilling. Implantation effect. c) Perform pre-treatment of the reinforcing material, cut the appropriate length such as hard steel or soft steel rope, etc., and make the convex processing at both ends and exposed parts of the suitable material. Before the formal implantation operation, the test sleeve can be made into the previously drilled hole. If the size d) the implant rubber is placed in the syringe, the reinforced rubber is mixed and extruded, initially 2~ 3 times the version of the hand to abandon, inject a proper amount of planting glue into the clean hole e) Insert the reinforcing material, need to slowly insert and properly vibrate the cloth to adhere the reinforcing material, and avoid the planting glue and mixing bubbles. (3) Lining treatment: In order to avoid the failure of the maintenance material to contact with the adjacent plates, it is necessary to use the lining to clean the surface of the filling surface before the maintenance of the material. The following steps are included: Prepare and confirm the application in depth. Secondly, because the cleaning work of the hole after drilling must be a non-reinforcing material (for example, when bending, and the reinforcing material can be added to increase the anchoring and gripping effect, the adjustment can be adjusted. The glue that is squeezed out by the plant should be thrown away. [Moving and rotating to create voids or bond between the soil and the joints, causing the joint material to be separated from the adjacent plate area 200825250. Another purpose of using the seaming material is to make the repair material. Form a complete seam pattern with adjacent sections to facilitate subsequent quilting operations. The lining plate should extend at least 25mm below the service section and extend at least 7 5mm at each end to prevent inflow of service materials. (4) Mixing and pouring maintenance materials: The maintenance materials can be selected from general concrete, non-shrinkage cement, hard epoxy resin, soft epoxy resin, composite cement, early strong coagulation. Soil, or suitable repair material, preferably general concrete, non-shrinkage cement, hard epoxy resin or composite cement, etc. Partial deep repairs are usually small in maintenance, so small mixing drums, mortar mixers or Other hand-held mixing tools and other tools for mixing, the ratio of various materials, order of addition, mixing procedure, mixing time should be based on the manufacturer's recommendations, the amount of one-time mixing depends on the size of the repair volume, the amount of manpower and the plan The repair time is determined. Before the repair material is placed in the maintenance section, it should be checked again whether there are loose concrete blocks and the repair surface is clean enough, and depending on the characteristics of the materials used, the repair section is recommended according to the manufacturer's recommendations. Surface treatment (for example, some materials require additional ® use of adhesives, etc.) (5) Compaction and leveling: After the cement maintenance materials are placed, they must be vibrated to remove air and make the repair materials fully fill the entire repair. Area. After the repairing material is finished, use a trowel to smooth the same surface with the screed. The trowel should be wiped from the center to the repairing edge. (6) Sweeping and curing: After smoothing the repair surface, the appropriate texture should be swept out on the repair shop, and the anti-sliding force of the pavement should be increased by -10- 200825250. After the action, appropriate maintenance measures should be used according to the manufacturer's recommendations. (7) Quilting: After proper curing time, after the repair material has developed the appropriate strength, remove the previously placed seaming material and The seam is cleaned and then quilted with quilting material to prevent moisture and debris from penetrating into the seam.

Fig. (E) shows the damage pattern of the rupture of the slab, wherein the double reinforcing materials 〗 〖i, 1 丨 are arranged diagonally diagonally along the service pit 10 and intersect each other. Fig. (F) shows the damage pattern of the edge crack of the plate, wherein the double reinforcing materials i i, n are arranged diagonally diagonally along the service pit 10 and intersect each other. -12- 200825250 According to the present invention, the foregoing embodiments are directed to the deep repair of the side edges and corner ruptures of the rigid pavement such as the airport pavement or the highway toll station, and the maintenance materials are selected from general concrete, non-shrinkage cement, and hard epoxy. Six different repair materials, such as resin, soft epoxy resin, composite cement and early strength concrete, are combined with the material properties and pavement damage, and the two methods of reinforcing the reinforcing material and the traditional unreinforcing strength. The inventor and other parts of the 87 group of deep maintenance application samples, after the completion of the maintenance project, the material strength reached the requirements of the setting of the tenth tenth, before the opening of the aircraft or the passage of the vehicle to tap the echo and super-sound The first test is carried out. The test items include the bottom bonding condition of the repair material and the wave speed of the repair material and the edge of the original block, and the test data is recorded. After the open flight or vehicle passes for six months, the same is also the first time. Detecting the same position at the same position, performing the second tapping echo and ultrasonic measurement 'other with visual and smashing sputum detection, and at the same time detecting the recorded data' using regression model statistical analysis to compare the maintenance results, and summarizing Good work method. Among them, the repair material is preferably general concrete, non-shrinkage cement, hard epoxy resin or composite cement. Although the performance of the soft epoxy resin repair is poor, it is not suitable for runway maintenance, but the material has the characteristics that the elasticity will not break or crack. It can be used for repairing the crack at the bottom of the repair. If it can strengthen the bonding effect, it can be a quick and effective repairing material. If the method of implanting the reinforcing material of the present invention is combined, the soft epoxy resin is not easy to get out of the repairing pit. Moreover, according to the average trend of statistical data, the repair effect of implanted reinforcing materials is better than that of traditional unreinforced materials. The aspect ratio of the better repair pit is 'length> visibility '1.5.
