Description of the Invention (/) [Technical Field of the Invention] The present invention relates to a repair method for road occupants such as manholes and the repair device used in the method. [Previous technology] Manholes installed on roads for the inspection of pipelines, gas pipes, underground burials of electricity and communications in the upper and lower sewers are damaged due to traffic loads, or due to subsidence of surrounding paving, When it becomes a traffic obstacle, it must be repaired. In the past, the repair and restoration was done by cutting or crushing the surrounding pavement of the buried road occupants with a cutter or crusher to remove it. However, due to noise problems, it was very difficult to work in residential areas at night. A construction method capable of performing the operation quickly and with safety in traffic and construction is disclosed in Japanese Patent Publication No. 63-55562. This method is to cut the pavement around the manhole into a circular shape with a sawing machine, pull the manhole cover frame and the surrounding pavement blocks together to remove it. In the repair of the pavement, epoxy resin concrete is used. Or fast-setting concrete, which can realize the opening of traffic early and improve the durability of paving. The hole sawing machine of the cylindrical cutter used in this construction method is composed of the body of the cylinder and a diamond piece installed at the front end thereof. The diamond piece is used to cut the paving surface by grinding. Therefore, when cutting, cooling water is required to cool the diamond chips and discharge the grinding chips. To ensure a considerable degree of cooling water, a water tank is required. In addition, the cooling water flows out of the pavement together with the grinding chips, which will pollute the surrounding environment, and it takes a lot of time to clean it. The cutter of the saw-hole model uses grinding to cut the pavement. The paper size of the cutter is applicable to China National Standard (CNS) A4 (210 X 297 mm). Please read the precautions on the back first (Fill in this page) '1 pack -------order --------- line ¢ 573 19 A7 * B7 V. Description of the invention (α) The object to be cut must be pressurized' for this' Cut-off vehicles need hydraulic devices for pressurization. The cut surface of the diamond pavement is smooth because the bone is cut, but because of the smooth surface, the integration with the resin concrete is not complete, resulting in the shear stress resistance of the new and old pavement materials. Poor's will also sink, fall, and crack after repair. In order to improve the adhesion of new and old paving materials, it is necessary to dry the cut surface with a burner and apply a primer to improve the integration with the resin concrete. operation. Furthermore, if the outdoor air temperature is low, in order to make the traffic of the resin concrete to be opened early with warm air curing, a warm air generator such as a jet heater must be prepared. As shown in Japanese Patent Utility Model Registration No. 3010469 of FIG. 4, there are also: a supporting claw is inserted between the manhole cover support frame and the manhole inclined wall, and the reaction force on the circular frame provided on the paving is used to Three manual jacks apply the force to support the manhole cover frame, so that the paving surface is cut along the edge of the frame, and the paving body and the manhole cover frame are removed at the same time. This method uses the force of a jack to peel the pavement, so it sometimes opens or supports the surrounding pavement. Moreover, due to the uneven cutting line, it has a considerable unevenness. Therefore, it is necessary to use a grinder to shape and cut. Extra steps in section. In addition, because the road surface has a horizontal section and a vertical section slope, sometimes the lower surface of the frame cannot fully contact the paving surface, resulting in a suspended portion, making the device unstable and preventing the operation from proceeding smoothly. In addition, in order to uniformly support the manhole cover frame, it is necessary to separately operate the jacks for adjustment, which is quite troublesome. [Problems to be Solved by the Invention] 4 (Please read the precautions on the back before filling out this page).-'Installation ------- Order · ---!

Description of the invention (multiple) In recent years, it has been used in sewage The manhole cover frame for communication lines such as assembled manholes or telephones is bolted to the upper part of the manhole. 'If the paving is only cut or cut along the manhole, the cover frame cannot be removed.' Therefore, it is necessary to crush the paving surface by the crusher and expose the bolts to release the fixing. Although the cutting of the paving surface can be reduced in noise, the noise of the crusher will halve the effect of the low-noise construction method. In order to prevent noise from the crusher, although it is proposed that the paving part of the bolt be pulled out by a coring drilling device as shown in FIG. 3 to expose the bolt, the nut is removed to release the fixing of the manhole cover frame, but Assembled manholes are different due to the arrangement of bolts by different manufacturers. Also, the number of bolts in the manholes in the sewer and the manholes for communication lines are not the same. It is necessary to explore the bolt location according to the manufacturer or type. It is difficult to specify the location of the paving cover. Furthermore, it is necessary to pull out the same number of pavements as the bolts with the core drilling device, which is time consuming. Therefore, the object of the present invention is to provide a method and device for repairing road occupants such as manhole cover frames, etc., without the need for a large-scale cutting device such as a sawing machine, and without the need to explore the position of the bolts or expose each bolt to release people. The hole cover is fixed and can be removed in a single step and the bolts are exposed. [Means to solve the problem] After the surrounding asphalt pavement is heated by non flame from the periphery and above the manhole cover frame, or from the inside, it can be easily carried out. The bolting of the asphalt pavement exposes the bolts to remove the manhole cover frame. 5 This paper size applies to Chinese national standards (CNS> A4 size (210 X 297 mm) (谙 Please read the unintentional matter on the back before filling in this page))

Description of the Invention (Jiang) The manhole repair method of the present invention can simultaneously cut and remove the surrounding pavement and fix the exposed manhole cover frame. Bolts can be constructed without having to explore the position of the bolts, so the construction efficiency can be improved. At the same time, the device can be simplified, and it can be completed with fewer operators. The enemy can construct at low cost. In addition, when melting asphalt pavement, if a direct flame such as a gas spray gun (§as bufnei ·) is used, the asphalt will be carbonized by the flame, or it is difficult to limit the heating range, and the asphalt pavement outside the removal range is also heated, causing the pavement Because of the adverse effects such as deterioration, it is easy to control the heating range. It is easy to control the heating range. Therefore, the surrounding asphalt pavement will not be heated and deteriorated, and the pavement material that is separated into the binder and the aggregate can be reused. The heating for melting the asphalt pavement is performed not only from the surface of the pavement, but also from the inside of the manhole cover frame. Therefore, the melting of the asphalt pavement also occurs from the inside of the pavement, enabling uniform and efficient heating. In addition, since only heating is performed without using a device such as a cutting device, the manhole cover frame can be removed without generating noise. In addition, because the combination of the releasing agent and the bone material is different from the cutting pavement of the cutter, the bone material can be maintained as it is without being cut, and the bone-like concave portion will remain on the removal section of the pavement for repair. At the same time, the new floor covering material will be applied to the recess, and it will be in a state of meshing with the existing floor covering. Therefore, the combination of the old and new floor coverings is strong, which can prevent the subsidence or cracks in the interface. In addition, the heating device of the repairing device used when removing the repairing material of the pavement can be used to heat the hardened pavement mixture. It is not necessary to prepare a warm air heating device such as a jet heater, and the repairing device of the present invention is used for heating. ί ί read the notes on the back before filling out this page.) --- Printed by the Consumers' Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs This paper is printed in accordance with China National Standard (CNS) A4 (210 X 297 mm) 4573 1 9 A7 B7 Printed by the Intellectual Property Bureau of the Ministry of Economic Affairs X Consumer Cooperative V. Invention Description u), the traffic can be opened early. [Embodiment of the Invention] The present invention will be described with reference to an embodiment of the drawings. Figure 1 is a cross-sectional view of the manhole cover frame when it is removed, showing the far-infrared heating device of the flameless heating device and the manhole cover frame repair device combined with the manhole cover frame removal device. The repairing device is arranged along the outer periphery of the manhole-shaped casing 1 along the outer periphery of the housing 1 to provide a cover 12 that can move up and down through the bracket 10, and a far-infrared heater 11 is provided inside the cover 12 »The cover 12 In order to effectively radiate the thermal energy of the far-infrared heater 11 on the road surface and prevent the heat from escaping, it is composed of a material with a small thermal conductivity coefficient, and the inner surface is lined with a material that reflects far-infrared rays. The lower end portion of the casing 1 is provided with a sharp blade portion 13 for ingestion of the noodles. If necessary, a driving device or a vibrating machine can be provided in the casing 1 to additionally shake, rotate or vibrate the casing 1. As shown in Fig. 2, the blade portion 13 has a built-in heater, so it is possible to heat the pavement from the blade portion 13 to promote the melting of the asphalt pavement. In addition, a beam portion 21 is provided on the upper part of the housing 1 at intervals, a jack 20 is provided on a fixed frame 22 provided on the beam portion 21, and a claw portion for supporting a manhole cover frame is provided at the front end of the jack 20. twenty three. The jack 20 is operated to insert the claw portion 23 under the manhole cover frame or the adjusting material. A spherical reflecting plate 30 facing downward is provided inside the housing 1, and a far-infrared heater 31 is arranged along the surface of the reflecting plate 30. On the upper part of the supporting claws 23 of the manhole cover support frame, a spherical shape 7 smaller than the inner diameter of the manhole is set. ≪ Please read the unintentional matter on the back before filling this page.) Applicable to China National Standard (CNS) A4 specification (210 X 297 mm) ^ 73 19 Λ7 _ 87 V. Description of the invention (Reflective plate) 32, above the reflective plate 32, can be configured to heat the manhole cover bearing from the inside Framing the far-infrared heater 33. The repairing device is set on the upper part of the manhole, and the asphalt pavement is heated by the far-infrared heater from the surface and the inside of the manhole cover support frame. After the heated asphalt pavement is melted to a state where it can be easily extracted from its surface, the repair device is removed from the manhole, and the molten asphalt pavement is extracted with a shovel, etc., so that the bolts fixing the manhole cover frame are exposed and loose Open the bolt to release the fixing. If the asphalt pavement cannot be melted to a depth that exposes the bolts with a single heating, a repair device is installed and heated again to expose the bolts. After removing the nut from the bolt, install a repair device to extend the support claw 23 on both sides of the meat, insert it between the manhole cover support frame and the inclined wall, and use the reaction force on the housing 1 to operate the jack 20 to support the manhole cover. At the same time, the blade portion 13 of the casing 1 is eaten into the melted and loosened pavement by about 2 to 5 cm with a reaction force, and cut off from the surrounding pavement to remove the manhole cover frame. Recover the heated and melted and separated aggregates and store them. Since the blade portion 13 of the casing 1 is eaten into the noodles, the upper portion of the cut surface has a regular round shape or a rectangular shape consistent with the shape of the casing. The front cutting edge portion 13 of the housing does not cut the bone like the previous cutter, so the trace after the bone is taken out becomes a concave portion and remains on the cut surface. Sweep the cut part, add a new binder, etc. to the recycled paving material that is adjusted and adjusted to make the manhole cover frame consistent with the paving surface, and lay it around the manhole cover frame and apply it. To roll. Or, do not recycle the recycled paving material, laying new asphalt mixture material or fast-setting concrete. 8 This paper size is applicable to China National Standard (CNS) A4 (210 X 297 mm) (Please read the precautions on the back first) (Fill in this page again) Install -------- * ~ tr '---- 11-line.

Description of the invention (7) 0 The repairing device is installed at the position of the manhole, and the heating device of the device is used to harden the paving surface. In addition, a temperature sensor (not shown) is installed in the heating device, and the heating device is controlled to a certain temperature to perform high-efficiency heating. In addition, if the shell 1 is loaded with bone and cannot be eaten into the noodles, vibration, shaking, or rotation may be applied to promote its subsidence. [Effects of the Invention] As described above, according to the manhole repair method of the present invention, since the asphalt pavement is melted by ore-free heating, it is not necessary to cut the periphery of the manhole cover support frame, so repair can be performed at low noise. If the manhole cover frame is fixed with bolts, it is not necessary to explore the position of the bolts, and the construction is easy, so it can be constructed at low cost. As the heating of the asphalt pavement is flameless heating, it is not necessary to heat beyond the necessary range. 5 It can be limited to heating the removed range only, and the asphalt pavement that does not need to be removed will not be deteriorated by heating. Because the asphalt pavement is flamelessly heated, the aggregate can be simply removed after the binder is melted, and because the shell is pressed into the pavement and then the surface layer is cut (fused) with the blade, the cut line is quite neat without bumps It is not necessary to perform the shaping of the cut surface, and the effect is very good. Because the bonding agent is separated from the bone material by heating, the bone material can be reused, and the concave portion after the bone material is removed is formed on the cut surface, and the combination with the repair material becomes strong. In addition, the heating device of the repairing device can be used for the heating and hardening of the repairing material, so it is not necessary to prepare a heating device for the hardening of the repairing paving. %) • --------! 1 (^ ------- line '· ((锖 Please read the notes on the back before filling in this page) A7 B7_ 5.
