Embodiment 1

[0053] Such as figure 1As shown, it is a kind of grouting equipment disclosed by the present invention, which includes a grout storage tank 1 with openings at both ends and a grouting mechanism 2 arranged in the grout storage tank 1. One of the openings of the grout barrel 1 is the grouting port 4, the other opening is the operating port 5, and one end of the grouting port 4 is provided with a sealing assembly 6 (refer to image 3 ).

[0054] Such as figure 1 As shown, the mobile frame 3 includes a rectangular bottom frame 7 and a pulley 8 rotatably connected to each of the four corners of the lower end surface of the bottom frame 7 . The mobile frame 3 also includes a rectangular sliding plate 9 fixed to the middle upper end surface of the longer two sides of the bottom frame 7, the sliding plate 9 is perpendicular to the bottom frame 7, and the middle part of the sliding plate 9 is provided with a sliding groove 10, The sliding groove 10 extends from the lower end surface...

Embodiment 2

[0067] A bridge crack repair method, comprising the following construction steps:

[0068] Step 1: measurement and recording of cracks, so as to screen and record cracks that can be surrounded by the sealing component 6;

[0069] Step 2: Target crack surface cleaning treatment:

[0070] 1) Use a wire brush to remove foreign matter around the crack;

[0071] 2) Use a hair dryer or organic solvent to remove the dust from the cracks and make them fully dry;

[0072] Step 3: Use grouting equipment to inject grout into the crack:

[0073] 1) Push the slurry storage tank 1 to the target crack, so that the sealing assembly 6 corresponds to the target crack;

[0074] 2) Open the closure assembly 23;

[0075] 3) Personnel stand on the bearing plate 11 at the same time, thereby applying a load to the two bearing plates 11, so that the sealing assembly 6 is in close contact with the bridge deck, and then through the deformation of the sealing assembly 6, a seal is formed between the ...

Abstract

The invention relates to a bridge crack repairing method. The bridge crack repairing method comprises the following construction steps that 1, crack measuring and recording are conducted; 2, target crack surface cleaning treatment is conducted; 3, grout is poured into cracks through grouting equipment; 4, maintaining is conducted; and 5, structure surface treatment is conducted. The bridge crack repairing method has the effect that fine cracks can be repaired more quickly.

Description

technical field [0001] The invention relates to the technical field of bridge repairs, in particular to a method for repairing bridge cracks. Background technique [0002] After the bridge is used for a long time, cracks will appear on its surface. In order to improve the service life of the bridge, it is necessary to repair the cracks in time. [0003] At present, all long cracks and short cracks are repaired in the same way, and the repair process is as follows: a grouting head is inserted into the crack, and then the crack is sealed with glue, and the grouting head is connected to the grouting equipment after the glue is solidified Filler is thus injected into the fracture. [0004] However, the glue used to seal the cracks takes a long time to set, generally at least 1 hour, which makes the construction efficiency not fast. Contents of the invention [0005] Aiming at the deficiencies in the prior art, the present invention provides a method for repairing bridge crac...
