A sliding type cavity pressing and injecting method for forming a plug pin film on the surface of a reinforced concrete beam, based on the sliding type cavity pressing and injecting device for forming the plug pin film on the surface of the reinforced concrete beam as claimed in any one of the claims 1-9, characterized in that: the method comprises the following steps:
s1, removing dust on the surfaces of a concrete beam and an upper floor slab to be pressed and injected, then moving a first pressing and injecting cavity and a second pressing and injecting cavity to the upper floor position and the lower floor position of the upper floor slab, and simultaneously moving two groups of hydraulic lifting and lowering moving frames to the tops of the upper floor slab and the lower floor slab respectively through universal wheels;
s2, scribing the top of the upper floor slab along the front side and the rear side of the concrete beam, measuring the distance between the through holes on the left side and the right side of the second injection cavity, marking the positions needing to be perforated on the line according to the hole distance of the through holes of the second injection cavity, and drilling the marked positions by using an electric drill;
s3, hanging the first injection cavity and the second cavity on the hanging hook by using hanging lugs, then starting the hydraulic cylinder, driving the moving block by a piston rod of the hydraulic cylinder, driving the moving block to move upwards at the same time, driving the first injection cavity and the second injection cavity to move upwards by the movable frame through the hanging hook and the hanging lugs, driving the hydraulic lifting moving frame to move upwards by using the universal wheels, moving the first injection cavity and the second injection cavity to the upper and lower positions of the through holes, connecting the first injection cavity and the second injection cavity in series by using the tightening bolt rod, simultaneously connecting nuts at the two ends of the tightening screw rod in a threaded manner, and then tightening the nuts to enable the first injection cavity and the second injection cavity to be attached to the upper and lower positions of the upper floor slab by using the rubber cushion blocks, and installing the first injection cavity and the second injection cavity after completion;
s4, injecting base liquid which can form a plug pin film from the base liquid injection port to the inner cavities of the first injection cavity and the second injection cavity, flowing the base liquid into the injection cavity through the base liquid injection port, flowing the base liquid into the hard sponge through the diversion trench, uniformly applying pressure to the surface of the concrete beam through the hard sponge, and then penetrating the base liquid into the concrete beam through the gap, and maintaining the preset pressure for a certain time to finish the injection of the base liquid;
s5, closing the injection pump, loosening the tension screw, rotating the hydraulic rod by 90 degrees, enabling the movable wheel to be attached to the upper floor slab and the concrete beam, utilizing the hydraulic up-down lifting movable frame to move the first injection cavity and the second injection cavity, then utilizing the tension screw to fix the first injection cavity and the second injection cavity again, and performing injection treatment on the concrete beam block by block to form the plug nail film.
