The present invention relates to a movable dual-component repair material injection apparatus for repairing a concrete structure and a method for repairing a concrete structure, which are to pump a main material and a hardener through the pumping motion of a piston and to effectively prevent the main material and the hardener from leaking to the outside during the pumping proces, and which are capable of freely moving to the cracks in the concrete structure to easily inject the repair material at a repair field to repair the cracks. The movable dual-component repair material injection apparatus for repairing a concrete structure comprises: a vehicle body frame which has movable wheels and a handle; first and second tanks which are loaded in the vehicle body frame and store a main material and a hardener, respectively; pumping units which pump the main material and the hardener respectively stored in the first and second tanks; a drive unit which drives the pumping units; and an injection nozzle which mixes the main material and the hardener pumped by the pumping units to form a repair material and injects the repair material into the cracks in a concrete structure.

The invention relates to a quick repair method for the bottom of the carbonization chamber of a coke oven. The repair steps are: 1. Preparation of tools and materials: 2. Setting of the furnace number: 3. Temperature control of the vertical fire path in the repair area: 4. Bricks at the bottom of the carbonization chamber Repair; 5. Insulation treatment of the carbonization chamber; so far, the maintenance work on the bottom of the carbonization chamber has been completed. In the future, when the bricks at the bottom of the carbonization chamber are found to be broken or fall off, the bottom of the carbonization chamber needs to be repaired according to the above steps.

The invention discloses an overhead ground wire repair device, which comprises a structural frame, an electric motor and a clutch which are connected. The electric motor is arranged inside the structural frame. An output end of the electric motor is connected with the clutch. A signal receiver for receiving a control command is arranged at the top of the electric motor. The clutch is provided witha first port and a second port. A traveling device is arranged above the first port. The traveling device is connected with the first port. A pressing mechanism is arranged above the second port. A repair device is arranged above the pressing mechanism. The repair device is connected with the structural frame. The pressing mechanism is used for pressing the repair device. The repair device is used for repairing an overhead ground wire. Instead of the staff, the overhead ground wire repair device can repair the overhead ground wire which is broken by using a repairing pipe, the efficiency of the repair work of the overhead ground wire can be increased, the stability of the power supply of a transmission line is ensured, the occurrence of disconnection accidents is avoided, and the repair effect is good.

An efficient integrated cleaning system and method for petroleum hydrocarbon organically polluted soil, the system sequentially includes a contaminated soil feeding unit, a pretreatment crushing unit, a microbubble entrainment cleaning unit, a discharge dehydration unit, a sewage treatment unit, and instruments and electrical control unit. The microbubble entrainment cleaning unit sequentially includes the first cleaning section and the third cleaning section; the first cleaning section includes a No. And No. ① contaminated soil turnover window located at the end of the first cleaning section; the third cleaning section includes No. ③ spiral scrubbing machine running through the third cleaning section, No. The end of the cleaning section is provided with a material discharge port, which is connected to the discharge dehydration unit. The invention improves the work efficiency of soil restoration and reduces the construction and operation costs of soil restoration. It can be widely used in the cleaning and treatment of polluted soil.

Disclosed is a fast safe solid expandable tube reinforcement device for oilfields. An expander is placed in an expandable patch tube in clearance fit in a broken well casing. The expander comprises a hydraulic tube and a fast inserting rod; the lower end of the hydraulic tube is connected to the upper port of the fast inserting rod, the lower end of the fast inserting rod is embedded in an expandable cone, and the cylindrical portion of the expandable cone tightly matches with the inner wall of an expandable chamber; a lifting rod penetrates the hydraulic tube, the fast inserting rod, the expandable cone in clearance fit from bottom to top, and the lower end of the lifting rod is tightly connected to a combined bottom plug; the combined bottom plug comprises a mandrel, and the mandrel penetrates a piston body, a two-way slip, is embedded in a guide cone holder and is fixedly connected with a pin. The device has the advantages that casing patching operation efficiency is improved greatly, the patching period is shortened, and significant economic benefits can be created. The device is characterized in that after pressing operation of the expandable tube is finished, the expandable cone moves upwardly till the upper port of the expandable tube and drives the lifting rod to move upwardly, the lifting rod drives the combined bottom plug to move upwardly, and the positioning part of the combined bottom plug can reduce automatically to relieve the limit and can be lifted out from the upper end of the expandable tube.

The invention provides a roof damage repairing bracket. The roof damage repairing bracket comprises a transfer box body, a plurality of vertically disposed first guide rails, a plurality of horizontally disposed second guide rails, a processor and a sensor. The multiple first guide rails are arranged around a house in a surrounding mode, and the multiple second guide rails are disposed above a rooftop of the house. The two ends of the second guide rails are correspondingly connected to the first guide rails, and the transfer box body is slidably disposed on the first guide rails and the secondguide rails. The transfer box body is internally provided with a material for repairing a building layer of the house. The sensor is disposed on the side wall of the transfer box body, and the sensoris connected with the processor. A user can store the repairing material in the transfer box body, the occupation of the roof space by the material is saved, the labor intensity of the user is reduced, the repairing work efficiency is improved, the repairing cost is reduced, the intelligentization of house repairing is realized, the installation and maintenance of the repairing bracket by the user are facilitated, and operation and use of the repairing bracket by the user are facilitated.
