摘要： PROBLEM TO BE SOLVED: To manufacture a repairing material for a small-size or small-area pavement in a necessary quantity in a construction site. SOLUTION: This device comprises a box 1 for heating and heat-retaining an asphalt mix, a screw conveyor 2 provided in the inner bottom of the box, and a tilting shoot 15 provided on the side part thereof. A heating source 4 of far infrared heater is provided on the inner surface of a lid 5, so that the asphalt mix can be heated to the using temperature within the box 1. Accordingly, a necessary quantity can be easily heated in the construction site and supplied for repair. The remaining asphalt mix is molded in a block shape and stored in a bag without disposing. The stored asphalt mix is put in the heating device when required and laid in the usable state.

摘要： PROBLEM TO BE SOLVED: To remove a pavement on a manhole opening by use of a simple device without using a cutter such as hole saw or the like and not generating noise. SOLUTION: The manhole opening 13 is blocked with a temporary lid 3, and a pavement 4 is constructed including the upper part thereof in a general manner. The asphalt pavement on a manhole 1 is non-frame heated with a far infrared heater 51 and molten, and the asphalt pavement 4 is divided into a binder and aggregate and removed to expose the manhole upper part. A manhole lid receiving frame 10 is set according to the gradient of the road surface, and a pavement material is filled around the manhole receiving frame 10 and rolled.

摘要： PROBLEM TO BE SOLVED: To facilitate connection even when an installing level and the direction of both pipes are different in a manhole for relaying the pipes. SOLUTION: This manhole A relays the two directional pipes B and C, and is constituted by respectively connecting a pipe installing member 1 for blocking up a bottom part by a bottom plate 1C, forming a connecting projection 1d for connecting one end of the pipe B to a prescribed position of a side wall 1a, and forming a groove 1h in an upper part, a straight wall member 3 connected to an upper part of the pipe installing member 1, and a socket member 2 forming a through hole 2c and a non-through hole almost equal to an inner diameter of the pipe C, forming an abutting surface 2b for abutting to an outer diameter of the pipe installing member in an end part, and forming a plurality of installing pieces 2f. The pipe installing member 1, the straight wall member 3, and the socket member 2 are molded by resin. Particularly when using waste plastic as the resin, a reusing method of the waste plastic is established so that work waste can be reduced. COPYRIGHT: (C)2003,JPO

摘要： PROBLEM TO BE SOLVED: To provide a repairing device for performing both a heating and a removal of manhole cover support frame in a repairing work to remove asphalt pavement around a manhole by heating. SOLUTION: A casing 1 incorporating a far infrared radiation heater 5 is installed on a frame 2 movably in vertical direction, and an asphalt pavement is noninflammably heated to fuse the pavement by the far infrared radiation heater 5 from around and inside the manhole cover support frame. The easing 1 is rotated to bite it into a road surface, and the molten asphalt pavement is removed. A breaking claw 4 attached at the tip 24 of a center shaft 20 is laterally extended and inserted into a clearance under the manhole cover support frame, and raised to remove the frame. Then, the material of the repaired pavement around the manhole is heated by the far infrared radiation heater 5 for curing the material.
