Resin injector for civil construction repairing and reinforcing

Abstract

The invention discloses a resin injector for civil construction repairing and reinforcing. The resin injector comprises a bottom plate and a box body fixedly arranged on the bottom plate. The box bodycomprises a liquid storage bin and a tool bin. A lifting pump is arranged in the tool bin. A connecting pipe is fixedly inserted into the inner wall of the liquid storage bin. One end of the connecting pipe extends into the tool bin and is installed at the suction end of the lifting pump. A hose is arranged at the output end of the lifting pump, and the other end of the hose communicates with a glue injection cylinder. Two fixing blocks are symmetrically arranged on the glue injection cylinder. Telescopic rods are arranged on the fixing blocks. A movable rod is arranged at the tail ends of the telescopic rods. A piston block is connected with a steel ball through a spring. When the telescopic rods stretch out, negative pressure is formed in the glue injection cylinder, resin glue in the hose is sucked into the glue injection cylinder, the telescopic rods are contracted, the resin glue is sprayed into a crack from a glue spraying opening, continuous glue injection is realized, and theworking efficiency and the working quality are improved.

Description

technical field [0001] The invention relates to the technical field of construction equipment, in particular to a resin injector for repairing and reinforcing civil engineering buildings. Background technique [0002] In building construction, after a long period of use, the wall surface will be damaged or cracked due to its own material problems or damage caused by daily life. At this time, it is necessary to inject repair and reinforcement into the gap with a syringe. Generally, workers inject directly through a syringe. The shape of this syringe is similar to that of a medical syringe. An injection seat is connected to the injection port at its front end. When in use, the injection seat is bonded to the crack (other parts on the surface of the crack Partially sealed with resin), use the injector to inhale the resin and then connect with the injection seat, the cylinder of the injector and the piston rod are connected externally with elastic rubber band or spring, and use ...

Problems solved by technology

[0003] The disadvantage of this type of injector is that after the injection of the resin glue in the injector, it is necessary to remove the injector and re-inject the resin glue into the injector, and then inject it. Continuous high-pressure injection cannot be performed. The operation is laborious and the previously injected resin glue It will block the injector to inject into the crack, which will affect the repair quality. Especially when repairing some high cracks, it is extremely inconvenient to move up and down to take the resin glue, and most of the cracks have different widths. In actual use, the staff Injectors of many different sizes need to be prepared, which is cumbersome to carry and expensive to manufacture
